Abstract

The invention relates to a method for compounding natural protein fiber powder on surfaces of polymer filaments, belonging to the technical field of new textile materials. The method comprises the steps of preparation of a blended solution, formation of polymer filaments with surfaces compounded with the blended solution and control of thickness, phase inversion primary formation of the polymer filaments with surfaces compounded with the blended solution and thermosetting formation of the polymer filaments with surfaces compounded with the blended solution, thus obtaining the polymer filaments with surfaces compounded with natural protein fiber powder. The polymer filaments with surfaces compounded with natural protein fiber powder have the characteristics of good strength, elasticity, hand feeling, surfaces rich in natural protein fibre powder, uniform distribution and the like, so that the polymer filaments have the characteristics of natural protein fibers and wide use values. The preparation method is simple to operate, dispenses with special equipment and achieves industrial production easily.

Description

technical field [0001] The invention relates to a method for compounding natural protein fiber powder on the surface of polymer filaments, belonging to the technical field of new textile materials. Background technique [0002] Natural protein fibers include silk, wool, cashmere, down, hair, rabbit fur, mohair, etc., which are renewable natural materials with excellent performance. At present, natural protein fibers are widely used in people's daily life. Except for clothing and bedding, most of them are simply processed and used as feed or degraded by fermentation. At the same time, the leftovers and waste fibers of natural protein fibers cannot Realize reasonable reuse, resulting in huge waste of resources. Therefore, it is of great significance to study new methods and new ways to realize the regeneration and efficient utilization of natural protein fiber resources. [0003] At present, there are two main methods to regenerate and spin natural protein fibers into protei...
