Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Republic of Korea Patent Application 10-2024-0193381, filed 20 Dec. 2024, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

1. Field of the Invention

The present invention relates to a hair cap for wigs and a method of manufacturing the same, and more particularly, to a hair cap for wigs that can be manufactured in a seamless manner and a method of manufacturing the same.

2. Discussion of Related Art

In the past, wigs were used as tools for covering a hair loss spot or supplementing an insufficient amount of hair. However, the number of cases in which wigs are used as cosmetic tools for trying a new hairstyle, beyond just supplementing an insufficient amount of hair, is increasing.

Treatments such as hair dyeing, perms, cuts, etc., are inevitable for trying various hairstyles, and such treatments have a problem that they are accompanied by hair damage. In addition, there are problems that such treatments require money and time, and after receiving one treatment, a certain amount of period has to pass before receiving an additional treatment in order to minimize hair damage. However, since wearing wigs makes various hairstyles possible without causing damage to hair or spending time, demand for various wigs is also increasing.

Accordingly, various products have been developed to meet increased demand for wigs that make natural hairstyles possible while not being noticeable when worn.

Generally, a wig that covers the entire scalp consists of hair and a hair cap. Here, the hair cap is divided into a plurality of areas for user's convenience in wearing the hair cap, and areas adjacent to each other are connected by sewing. However, when the areas adjacent to each other are connected by sewing, the user's wearing comfort may decrease due to sewn areas.

In addition, the hair may be fixed to the hair cap by sewing using a weft in the form of a hair bundle. However, when the weft is fixed to the hair cap by sewing, the user's wearing comfort may decrease due to sewn parts.

Further, when connecting different areas of the hair cap to one another or connecting the hair cap and the hair weft, sewing may be performed multiple times or an additional additive may be used to ensure firm connection.

However, the user's wearing comfort may decrease with additional sewing for connection. In addition, a chemical additive is used as the additive used for firm connection in most cases, and the chemical additive may affect the user's skin and cause skin irritation. Further, use of the chemical additive leads to a decrease in production speed.

FIG. 1 is a view for describing a wig according to one embodiment of the present invention. FIGS. 2A and 2B are views for describing one example of a hair cap. FIGS. 3A and 3B are views for describing another example of a hair cap. FIG. 4 is a view for describing a hair weft illustrated in FIG. 1. FIG. 5 is a view for describing a process of attaching the hair weft to the hair cap.

As illustrated in FIGS. 1 to 5, a wig 1000 according to one embodiment of the present invention may include a hair cap 100 and a hair weft 200. At this time, it should be noted that, in FIGS. 1 to 5, the final product is shown in an inside-out state to describe structures of the hair cap and the hair weft in more detail.

The hair cap 100 according to one embodiment may come into contact with the scalp of a person wearing the wig and may serve as a base to which hair is fixed.

More specifically, referring to FIGS. 2A to 3B, the hair cap 100 may be divided into at least two areas to enhance user's convenience in wearing the hair cap 100, and areas adjacent to each other may be firmly connected through a seamless type connecting member HMT. Therefore, the hair cap 100 may have a shape that corresponds to the user's head shape. For example, the hair cap 100 may include a first area 110 that corresponds to at least a portion of the user's head and a second area 120 that corresponds to the rest of user's head.

The first area 110 and the second area 120 may be made of a first fabric and a second fabric, respectively, and the first fabric and the second fabric may each be made of a mesh material that has a plurality of openings and is able to be attached to hair. That is, the first fabric and the second fabric that constitute the hair cap 100 may each include first fibers extending in one direction and second fibers extending in a direction intersecting the first fibers. In addition, sizes of the openings of the first fabric and sizes of the openings of the second fabric may be different.

In one embodiment of the present invention, the first area 110 and the second area 120 may be connected using the seamless type connecting member HMT. Here, the seamless type connecting member HMT may include a material that exhibits an adhesive property as it is cooled and solidified after being placed on an object to which the seamless type connecting member HMT is to be adhered and then being pressed to the seamless type connecting member HMT by applying heat and pressure. That is, the seamless type connecting member HMT may include a heat-sealable material. For example, the seamless type connecting member HMT may include at least one of a heat sealing type adhesive and a heat sealing type adhesive tape. For instance, the seamless type connecting member HMT may include a heat sealing type adhesive layer HM and a textile layer T (see FIG. 9) formed on the heat sealing type adhesive layer HM. At this time, the heat sealing type adhesive layer HM may be any one of a heat sealing type adhesive and a heat sealing type adhesive tape.

Meanwhile, a boundary line between the first area 110 and the second area 120 may be a heterogeneous boundary and may be formed by a predetermined cutting process CP after different fabrics, that is, the first fabric and the second fabric, are placed to overlap each other.

According to one embodiment, the predetermined cutting process CP may be ultrasonic cutting, hot knife cutting, laser cutting, laser-ultrasonic composite cutting, and the like. The predetermined cutting process provides a possibility that two fabrics that overlap each other may be bonded to each other provisionally or preliminarily when being cut, and in this way, since the two fabrics are not separated from each other in a subsequent cap manufacturing process that is performed after unfolding the two fabrics that were folded, the task can be more smoothly performed by a worker.

The above-described seamless type connecting member HMT is disposed to cover the boundary line between the first area 110 and the second area 120, and the first area 110 and the second area 120 may be connected to each other by applying heat and pressure to the seamless type connecting member HMT.

The first area 110 may be disposed to correspond to the front of the user's head. The direction toward the front of the user's head is indicated as “Front” in the drawings (see FIGS. 2B and 3B).

The first area 110 may have a lighter color than the second area 120 to reduce a color difference between the wig and the scalp. For example, the openings formed by the first fibers and the second fibers of the first area 110 intersecting with each other may be larger than the openings formed by the first fibers and the second fibers of the second area 120 intersecting with each other.

The second area 120 may be disposed to correspond to the rest, excluding the front, of the user's head, for example, the sides, top, and back of the user's head. That is, the second area 120 may cover the occipital region, the temporal region, and the parietal region of the user.

The openings formed by the first fibers and the second fibers of the second area 120 intersecting with each other may be smaller than the openings formed by the first fibers and the second fibers of the first area 110 intersecting with each other.

The second area 120 may include a plurality of sub areas to have a shape that corresponds to the head shape of the user.

For example, as illustrated in FIGS. 2A and 2B, the second area 120 may include a first sub area 121 and a second sub area 122. Here, the first sub area 121 and the second sub area 122 may each have a shape that extends from one temporal region to another temporal region of the user. In addition, the first sub area 121 may be an area that is more adjacent to the first area 110 than the second sub area 122.

In one embodiment of the present invention, the first sub area 121 and the second sub area 122 may be connected using the seamless type connecting member HMT. At this time, a boundary line B (see FIG. 9) between the first sub area 121 and the second sub area 122 may be a homogeneous boundary and may be formed by the predetermined cutting process CP after the same fabric, that is, the first fabric, is folded and portions of the first fabric are caused to overlap each other at least two times. Meanwhile, of course, even the above-described heterogeneous boundary may be illustrated as indicated by reference symbol B shown in FIG. 9 that relates to the homogeneous boundary.

As described above, the predetermined cutting process CP may be ultrasonic cutting, hot knife cutting, laser cutting, laser-ultrasonic composite cutting, and the like. Hereinafter, for convenience of description, an embodiment in which the predetermined cutting process CP is ultrasonic cutting may be described, but the present invention is not limited thereto.

Here, the seamless type connecting member HMT may include at least one of a heat sealing type adhesive and a heat sealing type adhesive tape. For example, the seamless type connecting member HMT may be disposed on a portion where the first sub area 121 and the second sub area 122 overlap, and heat and pressure may be applied to firmly connect the first sub area 121 and the second sub area 122 to each other.

As illustrated in FIGS. 3A and 3B, the second area 120 may include a first sub area 121, a second sub area 122, and a third sub area 123. Here, the first sub area 121, the second sub area 122, and the third sub area 123 may each have a shape that extends from an occipital region toward the front of the head of the user. For example, one end of each of the first sub area 121, the second sub area 122, and the third sub area 123 may be disposed toward the front of the head of the user, and the other end of each of the first sub area 121, the second sub area 122, and the third sub area 123 may be disposed toward the back of the head of the user. In addition, the second sub area 122 may be disposed between the first sub area 121 and the third sub area 123.

In one embodiment of the present invention, the first sub area 121 and the second sub area 122 may be connected using the seamless type connecting member HMT, and the second sub area 122 and the third sub area 123 may be connected using the seamless type connecting member HMT. A boundary line between the first sub area 121 and the second sub area 122 and a boundary line between the second sub area 122 and the third sub area 123 may each be a homogeneous boundary and may each be formed by the predetermined cutting process after the same fabric, that is, the first fabric, is folded and portions of the first fabric are caused to overlap each other at least three times.

In one embodiment of the present invention, the first sub area 121, the second sub area 122, and the third sub area 123 may be connected using the seamless type connecting member HMT. Here, the seamless type connecting member HMT may include at least one of a heat sealing type adhesive and a heat sealing type adhesive tape. For example, the seamless type connecting member HMT may be disposed on a portion where the first sub area 121 and the second sub area 122 meet, and heat and pressure may be applied to connect the first sub area 121 and the second sub area 122 to each other, and likewise, the seamless type connecting member HMT may be disposed on a portion where the second sub area 122 and the third sub area 123 meet, and heat and pressure may be applied to connect the second sub area 122 and the third sub area 123 to each other.

Meanwhile, the seamless type connecting member HMT disposed along a boundary line between sub areas, which is a homogeneous boundary, may be referred to as “first seamless type connecting member.” In addition, the seamless type connecting member HMT disposed along a boundary line between the first area 110 and the second area 120, which is a heterogeneous boundary, may be referred to as “second seamless type connecting member.”

Referring back to FIGS. 2A and 2B, the first seamless type connecting member and the second seamless type connecting member may cross each other, and a crossing section CR may be defined. The crossing section CR may be positioned on both ends of one of the first seamless type connecting member and the second seamless type connecting member. Accordingly, the crossing section CR may be positioned to be adjacent to a lower end of the hair cap 100 between an upper end and the lower end of the hair cap 100.

In addition, referring to FIGS. 3A and 3B, the first seamless type connecting member and the second seamless type connecting member may cross each other, a crossing section CR may be defined, and the crossing section CR may be positioned between both ends of the second seamless type connecting member. Accordingly, the crossing section CR may be positioned to be adjacent to an upper end of the hair cap 100 between the upper end and a lower end of the hair cap 100. This is in contrast with the case in which the crossing section CR is positioned to be adjacent to the lower end as in FIGS. 2A and 2B described above.

As described above, the wig according to one embodiment of the present invention may include the hair cap 100 divided into a plurality of areas. Here, areas adjacent to each other may be connected using the seamless type connecting member HMT, and therefore, compared to a wig having a hair cap in which areas adjacent to each other are connected by sewing, the wig according to one embodiment of the present invention may improve wearing comfort because seamless connection is possible.

Next, referring to FIGS. 2A to 3B, the hair cap 100 for wigs according to one embodiment of the present invention may further include a seamless type fixing member WB. The seamless type fixing member WB may be attached along a lower end of the second area 120.

The seamless type fixing member WB according to one embodiment is broadly similar to the above-described seamless type connecting member HMT but may include a relatively thick elastic material, which allows a lower end structure of the hair cap 100 to be formed. For example, as illustrated in FIGS. 2A and 2B, the seamless type fixing member WB may be attached along a lower end of the second sub area 122 to form the lower end structure of the hair cap 100. In addition, as illustrated in FIGS. 3A and 3B, the seamless type fixing member WB may be attached along the lower end of the second area 120 to form the lower end structure of the hair cap 100. Here, the lower end structure is a type of handle structure and may help the user of the wig 1000 easily wear the wig 1000.

At this time, the seamless type fixing member WB may have an overlapping section OR that overlaps at least one of the first seamless type connecting member and the second seamless type connecting member. This is because, as will be described below, the seamless type fixing member WB may also be attached to the hair cap 100 using a heat sealing method.

The seamless type fixing member WB may be attached to the hair cap 100 using a heat sealing method. For example, the seamless type fixing member WB may include a heat sealing type adhesive layer implemented by any one of a heat sealing type adhesive tape and a heat sealing type adhesive. For instance, the seamless type fixing member WB may include a heat sealing type adhesive layer and a textile layer formed on the heat sealing type adhesive layer. At this time, the heat sealing type adhesive layer of the seamless type fixing member WB may be the same as the heat sealing type adhesive layer HM of the above-described seamless type connecting member HMT, but as described above, the textile layer of the seamless type fixing member WB may be different from the textile layer of the above-described seamless type connecting member HMT in that it is made of a relatively thick elastic material.

Meanwhile, when the seamless type fixing member WB is attached to the hair cap 100, a comb COM1 may be attached together. The seamless type fixing member WB may be attached to the hair cap 100 using a heat sealing method as described above, and at this time, the seamless type fixing member WB may be attached to the hair cap 100 while the comb COM1 is disposed therebetween. In this way, a separate attaching process for the comb COM1 can be omitted, and the overall manufacturing process can be further simplified.

In addition, as illustrated in the drawings, a comb COM2 may be attached to another portion of the hair cap 100, and the combs COM1 and COM2 ensure that the hair cap is firmly fixed to the user's hair when worn.

Next, referring to FIGS. 4 and 5, the wig 1000 may have a structure in which a plurality of hair wefts 200 are fixed to the hair cap 100. Here, the hair wefts 200 may each have a form in which a plurality of strands of hair 210 are fixed while forming a band shape together.

The above-described hair wefts 200 may each include the plurality of strands of hair 210, a first seam 220, a second seam 230, and a seamless type adhesive layer HML.

At least one first seam 220 may be provided. The first seam 220 may be disposed across the plurality of strands of hair 210. The first seam 220 may define a folding reference area for a process of folding the strands of hair 210. The folding process may be a process of folding the strands of hair 210 along the first seam. The folding reference area may be disposed on one portion of the strands of hair 210 after the folding process.

The second seam 230 may define the folding reference area together with the first seam 220. The second seam 230 may fix the strands of hair folded along the first seam 220. At least one second seam 230 may be provided.

That is, the strands of hair 210 may be folded along the first seam 220, and the strands of hair may remain folded due to the second seam 230. In addition, the folding reference area may be defined by the first seam 220 and the second seam 230.

The seamless type adhesive layer HML applied to the hair weft 200 may be one modification of the above-described seamless type connecting member. In this sense, the seamless type adhesive layer may be referred to as “third seamless type connecting member.”

The seamless type adhesive layer HML may be formed in the above-described folding reference area along the first seam 220 and the second seam 230. For example, the seamless type adhesive layer HML may cover at least the folding reference area.

Heat and pressure applied to the seamless type adhesive layer HML may allow the plurality of strands of hair 210 to be fixed to the folding reference area defined by the first seam 220 and the second seam 230. Preferably, the plurality of strands of hair 210 may be firmly fixed, and in this way, an initial number of strands of the hair may be maintained without decreasing.

Here, the seamless type adhesive layer HML may include at least one of a heat sealing type adhesive and a heat sealing type adhesive tape. For instance, the seamless type adhesive layer HML may include the heat sealing type adhesive layer HM. It may be viewed that the seamless type adhesive layer HML does not have a textile layer, compared to the above-described seamless type connecting member HMT. At this time, the heat sealing type adhesive layer HM may be any one of a heat sealing type adhesive and a heat sealing type adhesive tape.

Meanwhile, an embodiment in which the seamless type adhesive layer HML applied to the hair weft 200 does not have a textile layer is mainly described in the present invention for convenience of description, but the present invention is not limited thereto. An embodiment having a textile layer is possible, and for example, the seamless type adhesive layer HML may be replaced with the above-described seamless type connecting member HMT.

Since the hair weft 200 formed as described above includes the seamless type adhesive layer HML, the strands of hair 210 may be prevented from being separated from the hair weft 200. For example, while the first seam 220 and the second seam 230 fix specific points of the strands of hair 210, the seamless type adhesive layer HML may fix the strands of hair 210 in a predetermined area of the strands of hair 210, for example, in the entire folding reference area. Therefore, compared to a case in which the strands of hair 210 are fixed using the first seam 220 and the second seam 230, separation of the strands of hair 210 from the hair weft 200 can be effectively prevented when the seamless type adhesive layer HML is used.

In one embodiment of the present invention, the hair weft 200 may be fixed to the hair cap 100 using the seamless type adhesive layer HML of itself.

In more detail, first, for example, the hair weft 200 to which the strands of hair are fixed may be disposed on the hair cap 100 using the seamless type adhesive layer HML. Then, when heat and pressure are applied to the hair weft 200, the seamless type adhesive layer HML may melt again. A portion of the melted seamless type adhesive layer HML may infiltrate the mesh material of the hair cap 100. Then, when the melted seamless type adhesive layer HML is cooled and solidified again, the hair weft 200 may be firmly fixed to the hair cap 100.

As described above, in the wig 1000 according to one embodiment of the present invention, the strands of hair 210 may be fixed through the seamless type adhesive layer HML, and heat and pressure may be applied to the seamless type adhesive layer HML again to fix the hair weft 200 to the hair cap 100. Therefore, compared to a wig in which the hair weft 200 is fixed to the hair cap by sewing, the wig 1000 according to one embodiment of the present invention is more convenient to manufacture. In addition, since it is possible to apply a material harmless to the human body to the adhesive layer, a weft that is eco-friendly and is safe even when in contact with the wearer's skin can be manufactured. In addition, the weft can be firmly attached to the cap, and a seamless natural exterior can be provided.

A method of manufacturing a wig according to one embodiment of the present invention will be described with reference to FIGS. 6 to 9 below.

FIG. 6 is a view for describing a method of manufacturing a wig according to one embodiment of the present invention. FIG. 7 is a view for describing a hair cap manufacturing step illustrated in FIG. 6. FIG. 8 is a view for describing a hair weft manufacturing step illustrated in FIG. 6. FIG. 9 is a view for describing a device used in the method of manufacturing a wig that is illustrated in FIGS. 6 to 8. FIGS. 10 and 11 are views for describing a sub area forming step illustrated in FIG. 7. FIGS. 12 and 13 are views for describing hair weft manufacturing illustrated in FIG. 8.

Referring to FIGS. 6 to 13, a method of manufacturing a wig according to one embodiment of the present invention may include manufacturing a hair cap (S100), manufacturing a hair weft (S200), and adhering the hair weft to the hair cap (S300).

In the manufacturing of the hair cap (S100), a hair cap 100 to which strands of hair 210 are fixed may be manufactured.

The hair cap 100 may be divided into at least two areas to enhance user's convenience in wearing the hair cap 100, and areas adjacent to each other may be connected for the hair cap 100 to have a shape that corresponds to the user's head shape. For example, as illustrated in FIGS. 1 to 5, the hair cap 100 may include a first area 110 that corresponds to at least a portion of the user's head and a second area 120 that corresponds to the rest of user's head.

The first area 110 and the second area 120 may be made of a first fabric and a second fabric, respectively, and the first fabric and the second fabric may each be made of a mesh material that is able to be attached to hair. That is, the first fabric and the second fabric that constitute the hair cap 100 may each include first fibers extending in one direction and second fibers extending in a direction intersecting the first fibers, and air permeability may be improved by openings formed due to the first fibers and the second fibers intersecting with each other.

The openings formed by the first fibers and the second fibers of the first area 110 intersecting with each other may be larger than the openings formed by the first fibers and the second fibers of the second area 120 intersecting with each other. That is, the number of the first fibers and the second fibers of the first area 110 per unit area may be smaller than the number of the first fibers and the second fibers of the second area 120 per unit area. Therefore, the first area 110 may have a lighter color than the second area 120. Since the first area 110 is disposed to correspond to a front portion of the user's head and has a lighter color than the second area 120, a color tone difference between the skin and the hair cap 100 may be reduced when the wig is worn.

The manufacturing of the hair cap (S100) may include a first fabric preparing step (S110), a sub area forming step (S120), a first seamless type connecting member attaching step (S130), a second fabric preparing step (S140), a first area forming step (S150), and a second seamless type connecting member attaching step (S160).

In the first fabric preparing step (S110), the first fabric is prepared. The first fabric may be made of a mesh material having a plurality of openings.

After the first fabric is prepared, the sub area forming step (S120) may be performed.

In the sub area forming step (S120), the first fabric may be cut, and sub areas of the second area 120 may be formed. The first fabric may be cut using an ultrasonic cutting process while at least two layers of the first fabric overlap each other. Meanwhile, a boundary between the sub areas formed by ultrasonic cutting may be heated at the time of ultrasonic cutting, and the sub areas may remain in contact with each other.

In one embodiment of the present invention, as illustrated in FIG. 10, when the first fabric is cut using an ultrasonic cutting process while two layers of the first fabric overlap each other, a first sub area 121 and a second sub area 122 may be formed. In addition, as illustrated in FIG. 11, when one side of the first fabric is cut using an ultrasonic cutting process while three layers of the first fabric overlap one another, and only two layers are present at both sides, a first sub area 121 and a second sub area 122 may be formed, and when the other side is cut using an ultrasonic cutting process, the second sub area 122 and a third sub area 123 may be formed.

After the sub areas are formed, the first seamless type connecting member attaching step (S130) may be performed.

In the first seamless type connecting member attaching step (S130), a first seamless type connecting member HMT may be attached along a boundary line between sub areas adjacent to each other to firmly connect the sub areas adjacent to each other.

To this end, the first seamless type connecting member HMT is disposed to cover the boundary line between the sub areas adjacent to each other. Then, when heat and pressure are applied to the first seamless type connecting member HMT, bonding portions of the sub areas adjacent to each other are firmly connected, and the second area 120 may be formed.

In addition, as illustrated in FIG. 9, placing the first seamless type connecting member HMT and applying heat and pressure may be simultaneously performed.

After the first seamless type connecting member HMT is placed along a boundary line between sub areas, for example, the first sub area 121 and the second sub area 122, through a second roller R2, the first seamless type connecting member HMT is supplied to pass between a base BS and a first roller R1.

The first seamless type connecting member HMT disposed along the boundary line between the first sub area 121 and the second sub area 122 may receive heat and pressure while passing between the base BS and the first roller R1. The first seamless type connecting member HMT may melt due to heat and pressure and may infiltrate the mesh material of the first fabric. Then, when the melted first seamless type connecting member HMT is cooled and solidified, a portion adjacent to the boundary line between the first sub area 121 and the second sub area 122 may be fixed by the first seamless type connecting member HMT. Therefore, the second area 120 may be formed.

Meanwhile, although FIG. 9 illustrates an example in which the base BS has a roller shape like the first roller R1 and the second roller R2, the present invention is not limited thereto. For example, the base BS may have a plate shape or a stage shape.

After the second area 120 is formed, the second fabric preparing step (S140) may be performed.

In the second fabric preparing step (S140), the second fabric for forming the first area may be prepared. Here, the second fabric may be made of a mesh material having a plurality of openings of which sizes are different from sizes of the openings of the first fabric.

When the second fabric is prepared, the first area forming step (S150) may be performed.

In the first area forming step (S150), after the second fabric is placed to overlap at least one of the sub areas of the second area 120, an ultrasonic cutting process may be performed to form the first area 110. As described above, a boundary between the formed first area 110 and second area 120 may be heated at the time of ultrasonic cutting, and the first area 110 and the second area 120 may remain in contact with each other.

When the first area 110 is formed, the second seamless type connecting member attaching step (S160) may be performed.

In the second seamless type connecting member attaching step (S160), a second seamless type connecting member HMT may be attached along a boundary line between the first area 110 and the second area 120 to firmly connect the first area 110 and the second area 120. To this end, the second seamless type connecting member HMT is disposed to cover the boundary line between the first area 110 and the second area 120. Then, when heat and pressure are applied to the second seamless type connecting member HMT, bonding portions of the first area 110 and the second area 120 are firmly connected, and the second area 120 may be formed. Therefore, it is possible to manufacture the hair cap 100 in which the first area 110 and the second area 120 are bonded.

In addition, as illustrated in FIG. 9, placing the second seamless type connecting member HMT and applying heat and pressure may be simultaneously performed.

After the second seamless type connecting member HMT is attached, a seamless type fixing member WB may be attached along a lower end of the second area 120 to form a lower end structure.

When the hair cap 100 is manufactured, the manufacturing of the hair weft (S200) may be performed.

In the manufacturing of the hair weft (S200), a hair weft 200 that is attached to the hair cap 100 to manufacture a wig may be manufactured.

The manufacturing of the hair weft (S200) may include a hair providing step (S210), a first seam forming step (S220), a folding process step (S230), a second seam forming step (S240), and a seamless type adhesive layer forming step (S250).

In the hair providing step (S210), a plurality of strands of hair 210 may be prepared and provided.

In the first seam forming step (S220), at least one first seam 220 that is disposed across the strands of hair 210 to define a folding reference area for a process of folding the strands of hair 210 may be formed. The first seam 220 may be formed through sewing.

When the first seam 220 is formed, the folding process step (S230) may be performed.

In the folding process step (S230), a folding process for preventing falling of the strands of hair 210 may be performed along the first seam 220. Due to the folding process, the folding reference area may be disposed on one end of the strands of hair 210.

In the second seam forming step (S240), at least one second seam 230 that defines the folding reference area together with the first seam 210 may be formed. Here, the folding reference area may be an area of the first seam 220 and the second seam 230. The second seam 230 may be formed through sewing.

When the second seam 230 is formed, the seamless type adhesive layer forming step (S250) may be performed.

In the seamless type adhesive layer forming step (S250), a seamless type adhesive layer HML may be attached to the folding reference area. Here, the seamless type adhesive layer HML may cover at least the folding reference area. The seamless type adhesive layer HML applied to the hair weft 200 may also be referred to as “third seamless type connecting member.”

The strands of hair 210 may be fixed using the seamless type adhesive layer HML covering the folding reference area. Therefore, the hair weft 200 may be manufactured. Here, the seamless type adhesive layer HML may cover the first seam 220 and the second seam 230.

The seamless type adhesive layer forming step (S250) may be performed using a device illustrated in FIG. 9.

First, after the seamless type adhesive layer HML is disposed on an area where the first seam 220 and the second seam 230 of the plurality of strands of hair 210 are formed, that is, the folding reference area, through the second roller R2, the seamless type adhesive layer HML is supplied to pass between the base BS and the first roller R1.

The seamless type adhesive layer HML may receive heat and pressure while passing between the base BS and the first roller R1. The seamless type adhesive layer HML may melt due to heat and pressure and may infiltrate that strands of hair 210, the first seam 220, and the second seam 230 of the folding reference area. Then, when the melted seamless type adhesive layer HML is solidified, the seamless type adhesive layer HML may strongly fix the strands of hair 210, the first seam 220, and the second seam 230 of the folding reference area. Therefore, the hair weft 200 may be manufactured.

By repeatedly performing the hair providing step (S210), the first seam forming step (S220), the folding process step (S230), the second seam forming step (S240), and the seamless type adhesive layer forming step (S250) as described above, a plurality of hair wefts 200 may be provided.

Meanwhile, although an example in which the manufacturing of the hair weft (S200) is performed after the manufacturing of the hair cap (S100) has been described in one embodiment of the present invention, the present invention is not limited thereto. For example, the manufacturing of the hair cap (S100) may be performed after the manufacturing of the hair weft (S200). In addition, the manufacturing of the hair cap (S100) and the manufacturing of the hair weft (S200) may be simultaneously performed at separate places.

When the hair weft 200 is manufactured, the adhering of the hair weft to the hair cap (S300) may be performed.

In the adhering of the hair weft to the hair cap (S300), the hair weft 200 may be attached to the hair cap 100 to manufacture the wig 1000.

The adhering of the hair weft 200 to the hair cap 100 may be performed using the device illustrated in FIG. 9. However, when adhering the hair weft 200 to the hair cap 100, a separate seamless type adhesive layer HML may not be supplied.

First, the hair weft 200 is disposed on the hair cap 100, and the hair cap 100 and the hair weft 200 are supplied to pass between the base BS and the first roller R1.

The hair cap 100 and the hair weft 200 may receive heat and pressure while passing between the base BS and the first roller R1.

The seamless type adhesive layer HML that was used to fix the strands of hair to the hair weft 200 may melt due to heat and pressure and may infiltrate the mesh material of the first fabric or the second fabric. Then, when the melted seamless type adhesive layer HML is cooled and solidified, the hair weft 200 and the hair cap 100 may be firmly connected, and the wig 1000 may be manufactured.

In this way, the cap and the weft are firmly attached using a heat sealing adhesive, and in this way, a seamless natural exterior is provided. As a result, when the wig is worn, there is no discomfort due to a thick sewing line, and the exterior of the wig looks even more natural.

As described above, in the wig 1000 manufactured through the method of manufacturing a wig according to one embodiment of the present invention, sewing is not used, different areas of the hair cap 100 may be connected using the seamless type connecting member HMT, and the hair weft 200 and the hair cap 100 may be connected using the seamless type adhesive layer HML of the hair weft 200 or a seamless type connecting member which is one modification thereof. Therefore, compared to a wig in which different areas of the hair cap are connected by sewing or the hair weft 200 is fixed to the hair cap by sewing, the wig 1000 manufactured by the method of manufacturing a wig according to one embodiment of the present invention may have improved wearing comfort.

In addition, compared to the existing wigs using chemical adhesives, the wig 1000 manufactured by the method of manufacturing a wig according to one embodiment of the present invention is eco-friendly and can minimize irritation to the user's skin.

According to the present invention, the user's wearing comfort can be improved because there is no thick sewing line inside a cap.

In addition, according to the present invention, since a separate toxic chemical adhesive (such as an adhesive made of volatile organic compounds (VOCs)) is not used, it is eco-friendly, and irritation to the user's skin can be minimized.

In addition, according to the present invention, process efficiency can be increased by reducing the number of manufacturing processes, and a firm seamless cap can be manufactured without sewing.

Further, according to the present invention, a cap that is lightweight and has high durability can be manufactured.

The present invention is not limited to the embodiments described above, and of course, a combination of at least two or more of the above embodiments or a combination of at least one of the above embodiments and a known art may be included as a new embodiment.

Although the present invention has been described in detail above using specific embodiments, the embodiments are only for describing the present invention in detail, the present invention is not limited thereto, and it is apparent that modifications or improvements to the embodiments can be made by those of ordinary skill in the art within the technical idea of the present invention.
