Problems solved by technology

Polyamide fiber is one of the common raw materials for preparing clothing due to its good wear resistance, long service life, and low price. However, compared with pure natural texture fabrics, its moisture absorption and moisture permeability are poor, and wearing stuffy
According to literature review, the collagen molecular chain contains a large number of hydrophilic groups such as amino groups and carboxyl groups, and the modification of collagen on the substrate can effectively improve the hygroscopicity of the substrate. Linear stacking blocks the original pores on the substrate, making its moisture permeability not ideal

Abstract

The invention discloses a preparation method of a vinyl collagen microsphere / polyamide fiber composite material. The method is specifically implemented according to the following steps of 1, modifying collagen by methacrylic anhydride to obtain vinyl collagen, and emulsifying and crosslinking the vinyl collagen to obtain vinyl collagen microspheres; 2, treating a polyamide fiber base material with formaldehyde to obtain hydroxylated polyamide fiber, and treating the hydroxylated polyamide fiber with MPS to obtain sulfhydrylated polyamide fiber; and 3, modifying the sulfhydrylated polyamide fiber base material with the vinyl collagen microspheres through thiol-ene click, thereby obtaining the vinyl collagen microsphere / polyamide fiber composite material. According to the composite material prepared by the method, on the basis of ensuring certain hygroscopicity, the moisture permeability of the fiber is further improved, the additional value of the fiber material is increased, the resource utilization of leather waste collagen is realized, and the application field of the collagen microspheres is enriched.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and in particular relates to a preparation method of a vinyl collagen microsphere / polyamide fiber composite material. Background technique [0002] People's life is inseparable from leather products, but some leather wastes are also produced during the leather production process. Directly discarding these wastes will pollute the environment and cause a certain waste of resources. These solid leather wastes can be extracted through a series of treatments. Get lots of collagen. Extracting collagen from tanning waste can not only reduce environmental pollution, but also provide new raw materials for other industries to achieve the purpose of recycling waste and turning waste into treasure. Polymer microspheres are widely used in many fields because of their special shape (spherical), good embedding performance, small size, large specific surface area, and enrichment of function...
