Because polylactic acid fiber is blended or interwoven with cellulose fiber such as cotton, viscose, modal and the like, alkali is used in dyeing and finishing, and the pH value of polylactic acid is weak acid, acid resistance and alkali resistance, so that the polylactic acid fiber is difficult to spin in matching; when the polyester is blended or interwoven with polyester, the polyester has dark color, especially black color, the dyeing temperature of the polyester can be only reached when the polyester is higher than 125 ℃ and reaches 130 ℃, and the polyester has safe processing temperature higher than 125 ℃ of polylactic acid, so that the hand feeling is obviously hardened and embrittled; when the acid dye is blended or interwoven with chinlon, the dyeing temperature of the acid dye is 95-100 ℃, alkali is rarely used in the dyeing and finishing process, the dyeing and finishing process is relatively proper, and the acid dye and the dyeing and finishing process are relatively proper in matching; therefore, the invention selects the collocation mode of the polylactic acid fiber yarn and the chinlon.
The chinlon has skin-friendly, cool, light and wear-resistant effects, although the chinlon contains more hydrophilic group amide-CONH and more polar group amino-NH2The absorbent can absorb more water to form direct and indirect water absorption, has better hygroscopicity, but has compact fiber structure and less gaps among fibers, only less indirect water absorption becomes capillary water, most water exists on the surface of the fibers to influence air permeability, so that the effects of dampness and tightness are brought, the absorbed water is not easy to volatilize and has poor quick-drying property, the daily wearing experience is damp and stuffy, and the wearer sweats and sticks to the skin when doing sports.
The polylactic acid fiber yarn is environment-friendly, skin-friendly, antibacterial and flame-retardant, can be compared with terylene due to the moisture regain of 0.5%, does not absorb water or regain moisture, but has a circular cross section, specks on the surface, irregular spots and discontinuous stripes longitudinally, a large number of non-crystalline parts, a large number of gaps among fibers and in the fibers, strong wicking effect, moisture permeability and air permeability far superior to those of the terylene, and is comfortable to wear in daily life and sports;
