[0030] Among them, outer layer is durable and wrinkle-resistant, so that the fabric is easier to maintain. Middle layer is air layer, its inside can store a large amount of air, utilizes the heat insulation performance of air, can provide good warmth retention effect. And polyester fiber is light and has good elasticity, so that middle layer has certain support and elasticity, again will not increase excessive weight, is beneficial to maintaining the lightness of the fabric. Inner layer has the skin touch of cotton and certain moisture absorption and perspiration performance, can provide comfortable wearing experience. Innermost layer is spandex layer, the elasticity of the spandex fiber is excellent, so that the fabric has excellent stretchability and recovery, can closely fit the body when worn, provides good wrapping and comfort, and enhances the warmth retention effect.

[0031] More specifically, the outer layer is formed by interweaving cotton yarn and profiled cross-section polyester filament, the light reflected by the profiled cross-section polyester filament is softer, and a unique texture effect can be formed, which is beneficial to improving the appearance of the fabric and making the fabric appearance have more texture and recognition.

[0032] The intermediate layer is knitted by using profiled cross-section polyester filaments, and the unique shape of the profiled cross-section polyester filaments can make the structure of the intermediate layer more loose, more gaps can be formed between the fibers, the warmth-keeping effect of the fabric is effectively enhanced, and the intermediate layer is more lightweight, the overall weight of the fabric and the wearing burden of the wearer are reduced.

[0033] The secondary inner layer is knitted by using round cross-section cotton-like polyester filaments, compared with the profiled cross-section polyester filaments, the fiber structure of the round cross-section is more stable and regular, and the texture is softer, the secondary inner layer can form smaller and more uniform gaps inside than the intermediate layer, the air storage capacity is enhanced, and the problem of uneven heat loss caused by the local thinness or thickness of the intermediate layer is avoided, and the warmth-keeping property of the fabric is further improved.

[0045] The cotton yarn is 40S / 1 combed cotton compact yarn, which has good strength, luster and fineness, and the surface is smoother and has less hairiness. The shaped cross-section polyester filament is DTY 83Dtex / 24F semi-dull polyester filament, which has moderate luster and is not too dazzling or completely without luster. The round cross-section cotton-like polyester filament is DTY 178Dtex / 108F full-dull polyester filament, which has good drape and can make the next inner layer more conform to the human body curve and more comfortable to wear. The spandex padding yarn is 33Dtex high-temperature-resistant semi-dull spandex filament.

[0046] The length of the fabric is controlled as follows: the length of the first path is controlled to be 20.2-20.7cm / 100 needles, and the lengths of the second, third, fourth, fifth, sixth, seventh and eighth paths are controlled to be 19.3-19.7cm / 100 needles.
