Embodiment 1
[0025] The polypropylene staple fiber yarn with a surface contact angle of 73° and a moisture regain of 0.2% is used for spinning, with a specification of warp density 360x weft density 290x warp 9.8x weft x, warp tightness > weft tightness, and five pieces of two-flying warp Satin woven fabric composition, such as figure 1 and figure 2 . Its polypropylene fabric meets the conditions of ①+②+③+④+⑤, see Table 1.
[0026] Because the warp floating length on the front side is larger than the weft floating length on the back side, that is, the warp yarns on the front side are covered more, and the weft yarns on the back side are covered more, and it is the warp support surface, so the warp yarns on the front side are directly and easily wetted; Contact, so the touch is comfortable, and as long as more weft yarns become larger, the sweat can be directly absorbed and spread out. When sweating and absorbing a lot, it can still absorb water in the fabric, and the dotted warp support...
Embodiment 2
[0029] Polyester staple fibers with a surface contact angle of 63° and a moisture regain of 0.2% are used, with specifications of warp density 320x weft density 280x warp 28x weft 21, warp yarn density > weft yarn density, and is composed of plain weave fabric with 1 upper and 1 lower . The polyester fabric satisfies the condition ①, see Table 1.
[0030] Because the warp yarn density is greater than the weft yarn density, that is, the front warp yarns cover more and the back weft yarns cover more, so the front warp yarns disperse moisture quickly; the back warp yarns have less contact with the skin, providing a comfortable and dry feeling.
[0031] Experiment: After loosening the sweat surface of the fabric, that is, friction and sand washing, the contact angle of the surface layer of the polyester staple fiber fabric in contact with the sweat surface is almost 0°. Under normal conditions, the original moisture regain of polyester fabrics is 0.2%. When the polyester fabric ...
Embodiment 3
[0033]The surface contact angle is 83°, the moisture regain is 0.2% ultra-fine polypropylene spinning, the specification is 320x weft density 320x warp 28x weft 14, the warp twist of the fabric is 100, and the weft twist is 80. Warp yarn density > weft yarn density, warp twist number > weft twist number, consisting of 2 upper and 2 lower twill woven fabrics. Its polypropylene fabric meets the conditions ①+②, see Table 1.
[0034] Because the warp yarn density is greater than the weft yarn density, and the number of warp yarn twists is greater than the weft yarn twist number, that is, the warp yarn on the front side is covered more, which is the warp support surface, and it is easy to disperse moisture directly; the warp yarn on the back side has a lower probability of contact with the skin, so it feels comfortable to the touch .
[0035] Experiment: After loosening the sweat surface of the fabric, that is, friction and sand washing, the contact angle of the surface layer of t...
