FIELD OF THE INVENTION

The present invention relates to a garment.

BACKGROUND

Conventionally, as a technique for joining a tape-shaped opening part that constitutes a garment to an opening of the garment, the following techniques are generally known: a method of stitching a tape-shaped opening part folded in two with an overlock sewing machine, and a method of stitching a tape-shaped opening part folded in three or four with a flat sewing machine or the like. In addition, a method of processing a collar part using a hot-melt sheet or adhesive dots is employed in recent years. For example, Patent Literature 1 proposes a technique in which an opening of an undergarment such as shorts is subjected to end processing using a tape made of a laminate of a hot-melt sheet and a stretchable fabric. In addition, Patent Literature 2 proposes a technique in which a tape-shaped patch cloth is pressure-bonded to an opening of an undergarment such as shorts using adhesive dots, and Patent Literature 3 proposes a technique in which, at an opening such as a collar of a T-shirt, a fabric of the opening is folded in two and pressure-bonded using adhesive dots and processed.

PATENT LITERATURE

  • Patent Literature 2: JP 2003-253510 A
  • Patent Literature 3: JP 2021-85103 A

SUMMARY OF THE INVENTION

Unfortunately, for example, the conventional general technique in which a tape-shaped opening part is folded in two, three, or four and stitched to an opening of a garment using an overlock sewing machine or a flat sewing machine has the following defect. Specifically, since a linear opening part is stitched to a curved opening, the inside of the opening part becomes excessive and undulated due to a difference between the inner and outer circumferences of the opening part. When a method of stitching the opening part while stretching the opening part is employed in order to solve the undulation of the opening part, the undulation of the opening part is alleviated. However, the method has a defect that a force by which the stretched opening part returns acts at the joint portion of the opening part, and a puckering defect occurs, that is, wrinkles appear on the garment main body side.

In addition, in the case of employing the technique of subjecting an opening of an undergarment such as shorts to end processing using a tape made of a laminate of a hot-melt sheet and a stretchable fabric as in Patent Literature 1, in the curved opening, a difference between the inner and outer circumferences occurs in the stretchable fabric made of the laminate of the hot-melt sheet and the stretchable fabric as in the conventional general technique, so that undulation occurs at the inside of the stretchable fabric.

Meanwhile, in the technique of Patent Literature 2, the joint of the opening part is not visible in appearance, and in the technique of Patent Literature 3, no opening part is used. Therefore, these techniques suffer from design restriction.

The present invention has been made in view of the above, and an object of the present invention is to provide a garment in which undulation of an opening part as well as a puckering defect of the opening part and a main body portion are reduced even in a case of a configuration in which the opening part is joined to a concave curved opening.

To solve the problem described above and to achieve the object, a garment according to the present invention is a garment having an opening through which a wearer's body passes. The garment includes: a garment main body provided with an opening part formed by folding a fabric, the opening part being joined along an edge of the opening of the garment main body. The opening part is fixed with adhesive dots provided in a plurality of rows along a mountain fold line and a fabric end of the fabric, and an average value LA of intervals between adjacent adhesive dots provided within a 3-cm section in a row of adhesive dots that are provided closest to a fabric end side of the opening part is smaller than an average value LB of intervals between adjacent adhesive dots provided within a 3-cm section in a row of adhesive dots that are provided closest to a mountain fold line side of the opening part.

In the garment according to the present invention, the LA and the LB have a relation of LA/LB≤0.75.

In the garment according to the present invention, the opening part is formed in a pattern having a concave curve with the opening being directed upward.

In the garment according to the present invention, the opening part has a curved shape having an inner periphery on the mountain fold line side and an outer periphery on the fabric end side when the opening part is not joined to the opening, and an angle formed by a tangent line at an end of the opening part on the fabric end side in a longitudinal direction of the opening part and a tangent line at an opposite end of the opening part on the fabric end side in the longitudinal direction is 10° or more and less than 180°.

In the garment according to the present invention, the LA and the LB have a relation of LA/LB≤0.7, and the opening part has a curved shape having an inner periphery on the mountain fold line side and an outer periphery on the fabric end side when the opening part is not joined to the opening, and an angle formed by a tangent line at an end of the opening part on the fabric end side in a longitudinal direction of the opening part and a tangent line at an opposite end of the opening part on the fabric end side in the longitudinal direction is 10° or more and less than 180°.

In the garment according to the present invention, the opening part has a stretch rate in a longitudinal direction of 20% or more and 200% or less, and the adhesive dots are fixed with the opening part being stretched.

According to the present invention, in the case of joining an opening part to an opening, the undulation of the folded opening part as well as a puckering defect of the opening part and a main body portion can be reduced.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Hereinafter, modes for carrying out the present invention (hereinafter referred to as “embodiments”) will be described with reference to the accompanying drawings. Note that the drawings are merely schematic.

First Embodiment

FIG. 1 is a drawing schematically illustrating a configuration of a garment according to a first embodiment. A garment 1 illustrated in the drawing is an example of an upper garment that is a short sleeve undergarment, and has a collar opening 2, sleeve openings 3, and a hem opening 4 through which a head, arms, and a torso pass, respectively. The collar opening 2, the sleeve openings 3, and the hem opening 4 are each formed in a pattern having a curve, that is, a pattern having a curvature larger than 0, and have a structure in which opening parts 5a, 5b, and 5c are joined thereto, respectively.

As a garment main body 1a, a woven or knitted fabric material provided as a general garment material, for example, a fiber structure such as a woven fabric or a knitted fabric can be used, but the garment main body 1a is not limited thereto. In addition, as for the application of the garment 1, the garment 1 can be applied to a material of outerwear such as a T-shirt and a jersey shirt in addition to a general undergarment and padded innerwear, and the application is not limited thereto.

The opening parts 5a, 5b, and 5c of the garment 1 are made of a stretchable fabric. For example, knitted fabric materials provided as general garment materials, such as stretchable weft-knitted and warp-knitted materials can be used. Examples of the weft knitting include plain knitting (plain stitch), ribbing (rib stitch), purl stitch (garter stitch), interlock stitch (smooth stitch), variations of plain knitting (such as plain stitch with different stitch density, moss stitch, herringbone stitch, float stitch, single jacquard, accordion stitch, lace stitch, plating stitch, pile stitch, cable stitch, and intarsia knitting), variations of ribbing (such as broad rib stitch, half cardigan stitch, full cardigan stitch, racked stitch, double jacquard stitch, half tubular stitch, Milano rib, double pique, and blister), and variations of interlock stitch (such as eight-lock, single pique, mock Milano, and ponte rome). Examples of the warp knitting include tricot (such as denbigh stitch, cord stitch, and atlas stitch) and Raschel knitting. In addition, a woven fabric material having stretchability for application to a garment is also suitable for the present invention.

The elongation of the opening parts 5a, 5b, and 5c of the garment 1 is preferably 20% or more and 200% or less, and more preferably 100% or more and 200% or less as measured by the elongation test method B of the Testing methods for woven and knitted fabrics described in “JIS L 1096 (2020)”.

The method for joining the opening parts 5a, 5b, and 5c to the garment main body 1a is not limited to stitching with an overlock sewing machine, stitching with a flat sewing machine, stitching with a flat seamer sewing machine, and stitching with a lockstitch sewing machine. In addition, apart from the joining method by sewing, it is also possible to join the parts by a pressure-bonding method using polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyether sulfone, polyether ether ketone, polyimide, polyamideimide, an adhesive containing a polymer compound, or a thermoplastic sheet.

As for the shapes of the collar opening 2, the sleeve openings 3, and the hem opening 4 of the garment main body 1a, it is preferable that each of the opening parts 5 (5a, 5b, and 5c) is formed in a pattern having a concave curve, that is, a pattern having a curvature larger than 0 with the opening being directed upward. FIG. 2 illustrates the opening part 5 (5a, 5b, or 5c) in a state of not being joined to the main body of the garment 1, and the angle formed by a tangent line 6ta at an end of the opening part 5 on a fabric end side in a longitudinal direction of the opening part 5 and a tangent line 6tb at an opposite end of the opening part 5 on the fabric end side in the longitudinal direction is preferably 10° or more.

The curvature in the present invention is determined by the following formula.

Curvature=1+average curvature radius(cm) of opening after fabric of opening part 5 is folded

Since the curvature is larger than 0, the opening part 5 can follow the curve of the opening of the garment main body, and the appearance quality with little wrinkles can be obtained. The curvature is more suitably 0.03 or more.

Hereinafter, the present invention will be described with the opening part 5a joined to the collar opening 2 being taken as an example. The opening parts 5b and 5c respectively joined to the sleeve opening 3 and the hem opening 4 have the same configuration as that of the opening part 5a, and can be manufactured in the same manner. FIG. 3A is a drawing illustrating manufacture of the opening part 5a of the garment 1 illustrated in FIG. 1, and is a drawing schematically illustrating a state before an opening part fabric 5a′ is folded. FIG. 3B is a drawing schematically illustrating a state after the opening part fabric 5a′ illustrated in FIG. 3A is folded and bonded. The opening part 5a is formed by folding the opening part fabric 5a′. Adhesive dots 10 are provided on one side of the opening part fabric 5a′. The adhesive dots 10 are provided in two rows along a mountain fold line 8 and a fabric end 6 of the opening part fabric 5a′. The adhesive dots 10 include a row of adhesive dots 107 that are provided on the fabric end 6 side and a row of adhesive dots 109 that are provided on the mountain fold line 8 side. In FIGS. 1 and 3B, the adhesive dots 10 are indicated by a solid line in order to facilitate understanding of the position where the adhesive dots 10 are provided.

For the manufacture of the opening part 5a, first, as illustrated in FIG. 3A, two rows of the adhesive dots 10 are provided on one side of one surface of the opening part fabric 5a′, and then the part fabric 5a′ is folded in two at the mountain fold line 8. Thereafter, the opening part fabric 5a′ is fixed with the adhesive dots 10 in a state where the opening part fabric 5a′ is longitudinally stretched by 110% to 190%, preferably by 120% to 180%. After the fixing with the adhesive dots 10, when the stretching of the part fabric 5a′ is released, the part fabric 5a′ contracts more largely at the mountain fold line 8 side than at the fabric end 6 side. Thus, it is possible to provide the opening part 5a having a concave curved shape having the inner periphery on the mountain fold line 8 side and the outer periphery on the fabric end 6 side.

Alternatively, two rows of the adhesive dots 10 are provided on one side of one surface of the opening part fabric 5a′ as illustrated in FIG. 3A in a state where the opening part fabric 5a′ is stretched by 110% to 190%, preferably by 120% to 180% in advance, then the part fabric 5a′ is folded in two at the mountain fold line 8 and fixed with the adhesive dots 10, and then the stretching of the part fabric 5a′ is released. This method is also preferable because the concave curved shape can be obtained.

The opening part 5a is folded in two in FIGS. 3A and 3B, but the folded shape is not limited thereto, and the opening part 5a may be folded in three or four.

FIG. 4 is a drawing illustrating an interval between the adhesive dots 10 provided on the opening part 5a of the garment illustrated in FIG. 1. As illustrated in FIG. 4, an average value LA of intervals between adjacent adhesive dots 107 provided within a 3-cm section in a row of adhesive dots 107 that are provided on the fabric end 6 side of the opening part 5a of the garment 1 is smaller than an average value LB of intervals between adjacent adhesive dots 109 provided within a 3-cm section in a row of adhesive dots 109 that are provided on the mountain fold line 8 side of the opening part 5a of the garment 1. In the garment 1 of the present invention, the average value LA of intervals between adjacent adhesive dots 107 provided within a 3-cm section in a row of adhesive dots 107 that are provided on the fabric end 6 side of the opening part 5a and the average value LB of intervals between adjacent adhesive dots 109 provided within a 3-cm section in a row of adhesive dots 109 that are provided on the mountain fold line 8 side of the opening part 5a preferably have a relation of LA/LB≤0.75, and more preferably have a relation of LA/LB≤0.7. Since LA and LB satisfy the above-mentioned relation, when the opening part 5a is formed into a curved shape and joined to the collar opening 2, undulation and puckering can be avoided. The average value LA of intervals between adjacent adhesive dots 107 provided within a 3-cm section in a row of adhesive dots 107 that are provided on the fabric end 6 side and the average value LB of intervals between adjacent adhesive dots 109 provided within a 3-cm section in a row of adhesive dots 109 that are provided on the mountain fold line 8 side can be calculated from the following formulae.

Average ⁢ value ⁢ LA = ∑ k = 1 n a ⁢ Δ ⁢ LA k n a ( 1 ) Average ⁢ value ⁢ LB = ∑ k = 1 n b ⁢ Δ ⁢ LB k n b ( 2 )

• • n_a: (number of adhesive dots 107 provided within 3-cm section)−1
  • nb: (number of adhesive dots 109 provided within 3-cm section)−1
  • ΔLA: interval between adjacent adhesive dots 107 provided within 3-cm section in row of adhesive dots 107 provided on fabric end side
  • ΔLB: interval between adjacent adhesive dots 109 provided within 3-cm section in row of adhesive dots 109 provided on mountain fold line side

In addition, when a distance d1 from the row of adhesive dots 107 that are provided on the fabric end 6 side to the fabric end 6 is long, the opening part 5a has a long free end on the fabric end 6 side, so that defects such as undulation of the end are likely to occur. Therefore, the distance d1 from the row of adhesive dots 107 to the fabric end 6 is preferably within 2 mm, and more preferably within 1 mm. The lower limit of the distance d1 is not particularly limited and can be appropriately set according to the size of the dot and the like, but the distance d1 is usually preferably 0.2 mm or more. Furthermore, when a distance d2 from the mountain fold line 8 to the row of adhesive dots 109 that are provided on the mountain fold line 8 side is short, the adhesive dots 109 are scattered in the vicinity of the mountain fold line 8 of the opening part 5a, so that defects such as pressure-bonding deformation of the mountain fold line 8 are likely to occur. Therefore, the distance d2 from the mountain fold line 8 of the fabric to the row of adhesive dots 109 is preferably 0.5 mm or more. The upper limit of the distance d2 is not particularly limited, but the distance d2 is usually preferably 10 mm or less.

The adhesive dots 10 provided on the opening part 5a are preferably made from a synthetic resin rather than a natural resin. Among synthetic resins, a thermoplastic resin is more preferable. The adhesive dots 10 are not particularly limited as long as they are made from, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyether sulfone, polyether ether ketone, polyimide, polyamideimide, or a polymer compound, and various materials can be used.

The adhesive dots 10 provided on the opening part 5a are preferably made from a reactive hot-melt resin. When the resin is a reactive hot-melt resin, the resin softens or melts and penetrates between the structures of the bonding site, and reacts with surrounding moisture after cooling and solidification. As a result, crosslinking proceeds, and an adhesive structure excellent in heat resistance, solvent resistance, and the like can be formed.

A preferable size of the adhesive dots 10 varies depending on the structure and thickness of the fabric that constitutes the garment 1. When the dots have a diameter of about 1.0 to 2.0 mm, relatively high adhesion strength can be easily obtained. However, the dots may bleed out to the front side of a thin fabric to be conspicuous, and may impair the appearance. Therefore, the dots are preferably small within a range in which the required adhesion strength is obtained. Adhesive dots having a diameter of 1.0 mm or less are preferable because such adhesive dots hardly bleed out even in the case of a fabric for innerwear having a fabric thickness of about 0.5 to 0.8 mm. Furthermore, adhesive dots having a diameter of 0.6 mm or less are preferable because the bleeding is hardly conspicuous even in the case of a thinner fabric having a fabric thickness of about 0.3 to 0.5 mm. In a case where the adhesive dots have a small diameter and have a low adhesion strength, it is possible to reinforce the adhesion by reducing the interval between the adhesive dots. In the present specification, the diameter of the adhesive dots is intended to mean the length of the adhesive dots in the planar direction. The adhesive dots when being provided on the fabric end have a height almost the same as the diameter thereof, but the adhesive dots penetrate into the fabric when the fabric is fixed with the adhesive dots. Therefore, the adhesive dots have no influence on the thickness of the garment 1.

The adhesive dots 10 have a circular shape in the first embodiment, but the shape of the adhesive dots 10 is not limited thereto. The adhesive dots 10 may have any shape as long as the adhesive dots 10 can be successively provided in a separated state so that the interval between the adhesive dots can be changed, and the adhesive dots 10 may have a linear shape, a geometric shape, or a shape obtained by combining these shapes.

The resin that constitutes the adhesive dots 10 preferably has a hardness of 10 to 90 in terms of the durometer D hardness measured according to the plastic durometer hardness test method described in “JIS K 7215 1986”, and the hardness is more preferably 10 to 60.

The resin that constitutes the adhesive dots 10 preferably has a specific gravity of 1.00 to 1.30 measured according to the method for measuring specific gravity of plastics described in “JIS K 7112 1999”, and the specific gravity is more preferably 1.10 to 1.20.

As described above, in the garment 1 according to the first embodiment, the average value LA of intervals between adjacent adhesive dots 107 in a row of adhesive dots 107 that are provided on the fabric end 6 side of the opening part 5a is smaller than the average value LB of intervals between adjacent adhesive dots 109 in a row of adhesive dots 109 that are provided on the mountain fold line 8 side of the opening part 5a. Therefore, the opening part 5a can be formed into a curved shape, so that undulation that occurs when the opening part 5a is joined to the collar opening 2 as well as puckering can be avoided.

In the first embodiment, the adhesive dots 10 are provided in two rows, but the number of rows is not limited thereto, and the adhesive dots 10 may be provided in three or more rows. FIG. 5A is a drawing illustrating manufacture of an opening part 5a of a garment according to a modification of the first embodiment, and is a drawing schematically illustrating a state before a fabric is folded. FIG. 5B is a drawing illustrating manufacture of the opening part 5a of the garment according to the modification of the first embodiment, and is a drawing schematically illustrating a state after the fabric illustrated in FIG. 5A is folded and bonded. In FIGS. 5A and 5B, four rows of adhesive dots 107, 107A, 109, and 109A are provided. When three or more rows of the adhesive dots 10 are provided, the adhesive dots 10 should be provided so that the average value LA of intervals between adjacent adhesive dots 107 provided within a 3-cm section in a row of adhesive dots 107 that are provided closest to the fabric end 6 side of the opening part 5a is smaller than the average value LB of intervals between adjacent adhesive dots 109 provided within a 3-cm section in a row of adhesive dots 109 that are provided closest to the mountain fold line 8 side of the opening part 5a.

In FIGS. 5A and 5B, as for the adhesive dots 107 and the adhesive dots 107A, the average value of intervals between adjacent adhesive dots provided within a 3-cm section is the same, and as for the adhesive dots 109 and the adhesive dots 109A, the average value of intervals between adjacent adhesive dots provided within a 3-cm section is the same. As for the rows of adhesive dots 10, it is more preferable that the average value of intervals between adjacent adhesive dots provided within a 3-cm section in one row increases from the fabric end 6 side toward the mountain fold line 8 side.

Second Embodiment

FIG. 6 is a drawing illustrating a configuration of a garment 20 according to a second embodiment. The garment 20 illustrated in the drawing is an example of a lower garment as an undergarment, and has a waist opening 21 and leg openings 22 through which legs and a torso pass, respectively. The waist opening 21 and the leg openings 22 are each formed in a pattern having a curve, that is, a pattern having a curvature larger than 0, and are each concave curved with the opening being directed upward. Opening parts 5d and 5e are joined to the waist opening 21 and the leg openings 22, respectively. As for the opening parts 5d and 5e, an average value LA of intervals between adjacent adhesive dots 107 provided within a 3-cm section in a row of adhesive dots 107 that are provided on the fabric end 6 side of the opening parts 5d and 5e is smaller than an average value LB of intervals between adjacent adhesive dots 109 provided within a 3-cm section in a row of adhesive dots 109 that are provided on the mountain fold line 8 side of the opening parts 5d and 5e, and the opening parts 5d and 5e are curved and deformed. It goes without saying that the effect of the present invention can be obtained also in the second embodiment in the same way as in the first embodiment.

Modes for carrying out the present invention have been described above, but the present invention should not be limited by the above-mentioned embodiments. For example, the present invention is also applicable to openings of garments such as hats and arm covers.
