Abstract

The invention discloses a finishing method capable of preventing Modal fibers from pilling and belongs to the technical field of textile materials. The finishing method includes: mixing man-made spider fibers and silk fibers, adding protease and water, stirring and mixing, and performing rotary evaporation and concentration to obtain mixed fiber concentrate; mixing a eucommia ulmoides gum emulsionwith an oxidizing agent, and performing stirring reaction to obtain an oxidized eucommia ulmoides gum emulsion; mixing the Modal fibers with liquid ammonia, performing reaction under normal temperature and high pressure to obtain activated Modal fibers; mixing the mixed fiber concentrate and the oxidized eucommia ulmoides gum emulsion, adding a dewatering agent, performing stirring reaction, standing, and filtering to obtain a modified eucommia ulmoides gum emulsion; mixing the activated Modal fibers with the modified eucommia ulmoides gum emulsion, adding a catalyst, performing stirring reaction, and filtering, pre-baking, baking and discharging to obtain the Modal fibers resistant to pilling. The finishing method has the advantages that the Modal fibers finished by the method can keep original strength, the pilling resistance of the Modal fibers is increased, and the dry modulus of the Modal fibers is also increased.

Description

technical field [0001] The invention discloses a finishing method for modal fibers against pilling and belongs to the technical field of textile materials. Background technique [0002] Modal fiber is a new type of cellulose fiber with high wet modulus. It has very good performance. It combines the softness of cotton, the moisture absorption capacity of viscose, and the luster of real silk. It is a biodegradable fiber that is favored by consumers. Modal has the characteristics of uniform high-strength fibers, good spinnability and textile performance, and can be processed and dyed by traditional methods. Modal fabric has the characteristics of good water absorption and breathability, soft and smooth, comfortable and smooth. Modal is mainly used in the manufacture of people's underwear and home textiles. Its soft and smooth properties will make people wear very healthy and comfortable. It can also be blended with other materials to form fabrics with different feelings. Howe...
