Woolen sweaters are molded products, and it is difficult to use singeing or shearing methods to prevent pilling. Recently, the commonly used anti-pilling finishing processes mainly include mild napping and resin finishing. The effect of resin finishing method is better.

Shrinkage-proof finishing

Scale is one of the main characteristics of wool fiber, it makes the wool fiber has a felting, so the essence of shrink-proof finishing is to deal with the scale, so that it weakens or loses the directional friction effect. Mainly the use of chemicals and scales, damage and softening scales; or the use of resin uniform diffusion on the surface of the fiber, the formation of a film. So as to effectively limit the role of scales, so that the wool fiber loses the fleece, to achieve the purpose of anti-shrink.

Mothproof finishing

Moth-eaten wool sweaters often occur during storage. So that the moth can not survive on the fabric, can achieve the purpose of mothproof, this is the task of mothproof finishing. The auxiliaries used for moth-proof finishing should be high efficiency and low toxicity, have no side effects on the human body, do not affect the color and color fastness of the fabric, do not damage the wool feel and strength of the wool fiber, and have the characteristics of washing, sun resistance and lasting resistance. Commonly used moth-proof finishing methods are chemical modification of wool and moth-proof agent finishing method.
