Description

Wool mixed spun yarn with excellent wear resistance and laundering resistance and manufacturing method thereof

The present invention relates to a wool blend spun yarn for socks that is excellent in washing resistance and abrasion resistance and excellent in heat retention, and a method for manufacturing the same.

Wool fiber is an animal-derived natural fiber manufactured from wool, has low thermal conductivity, and has a lot of air between the fibers, so it is light and warm. In addition, it has antibacterial and deodorant functions, so it reduces foot odor. It has good elasticity, so it is comfortable to wear, and the feeling of tightness in the foot is reduced, which improves blood circulation and helps skin beauty by absorbing oil from the skin.

However, compared to chemical staple fibers or cotton fibers, wool fibers are severely contracted by hot water, friction, and alkaline detergents due to their unique fiber structure. It cannot be completely prevented, and there is a disadvantage that care must be taken even when drying. In general, in order to prevent the shrinkage of wool fibers in water washing, the scales on the surface of the wool fibers are dissolved in hydrochloric acid and coated with resin to enable water washing. However, this method promotes environmental load and entails deterioration of the original performance of wool fibers, and when socks are made with modified wool fibers, sweat easily permeates, causing severe hair loss of wool fibers, increasing costs due to chemical treatment, and environmental protection. There was also the problem of not being environmentally friendly. In addition, hygroscopicity is twice as strong as that of cotton, so sweat generated from the body during active activity can be absorbed as it is, but there is a disadvantage that it cannot be effectively discharged and thus comfort cannot be maintained.

According to the Republic of Korea Patent Publication No. 10-0546035, clothes were manufactured by blending wool fibers and polyester staple fibers to solve the above problems. However, clothes manufactured by simple blending with conventional polyester fibers shrink Not only did it not effectively relieve the sweat, but only the hygroscopicity was still strong.
