For the fabric body 1 in which a thermal fuse is not used, the high-temperature treatment is to allow the fabric body 1 to fully shrink under heat to obtain a suitable fabric body 1; and for the fabric body 1 in which the thermal fuse is used, the high-temperature treatment is required to melt and bond the thermal fuse inside the fabric body 1 to obtain a suitable fabric body 1.

In the present embodiment, the polyester high stretch yarns are used to knit the first face layer 31 and the first bottom layer 32 of the fabric, so that the fabric has a certain support and extensibility, positions where the monofilaments are knit are transparent, and gaps of the monofilament yarns greatly improve air permeability, causing the fabric to have an overall fine and compact structure, a small thickness, and high stability. In the present embodiment, the fabric is formed by integral knitting, causing the fabric to have good air permeability, high structural stability, fine and compact overall knitting effect, and a simple manufacturing method.

After the knitting is completed, it is necessary to perform finish-ironing at a temperature of 80° C. to 200° C., which is called “activation” treatment. A specific temperature is 160° C., so that a surface layer of the TPU material is slightly melted, and the TPU materials will adhere to each other with a certain supporting force after cooling. The resultant fabric body 1 is fine, clean and neat, and comparable to a warp-knitted jacquard sandwich fabric.

In the present embodiment, the TPU material is used to knit the second face layer 41 of the fabric, the polyester high stretch yarns and the TPU materials are used to knit the second bottom layer 42 of the fabric, and the transparent monofilaments are used to knit the intermediate support layer 43 of the fabric, so that the fabric presents a sandwich effect; the fabric knit from the second face layer 41, the second bottom layer 42 and the intermediate support layer 43 has a similar style to the warp-knit jacquard fabric, and has very fine and delicate visual effect and texture. In the present embodiment, the high-temperature treatment of the fabric improves physical properties of the fabric, resulting in good abrasion resistance and good support; and the fabric manufactured by the manufacturing method according to the present embodiment improves comfortability of the fabric, resulting in clean and tidy overall appearance. In the present embodiment, the fabric is formed by integral knitting, causing the fabric to have good air permeability, high structural stability, fine and compact overall knitting effect, and a simple manufacturing method.
