Problems solved by technology

[0004] In the prior art, when grafting silk protein, it often needs to be pretreated with concentrated sulfuric acid to proceed smoothly. However, concentrated sulfuric acid will damage the fabric and is not conducive to environmental protection.
And these methods of prior art have solved the pilling problem of rabbit fur knitted fabric to a certain extent, but can damage fiber, change the style of fabric, limit fabric color

Abstract

The invention discloses a new process for modifying rabbit hair fiber grafted silk protein. The process does not use protease, is harmless to fiber, is natural and environment-friendly, and does not use a chemical raw material. The rabbit hair cloth produced through the process is relatively soft and delicate in hand feeling, and low in possibility of pilling, and also has particular glossiness. The anti-pilling grade of the produced rabbit hair cloth can reach 4-5, and the possibility of pilling is low.

Description

Technical field [0001] The invention relates to a process for grafting rabbit hair fiber with silk protein to modify, and belongs to the textile field. Background technique [0002] Rabbit hair feels soft, light and fluffy, unique in style, good in warmth retention and moisture absorption, but because of the unidirectional scales on the surface of rabbit hair fiber, the fiber strength is low, the surface friction performance is poor, the degree of curl is small, and the cohesive performance is poor. It is easy to shed, shrink, and pilling when used in medium. [0003] The resin-type crosslinking agent sucrose fatty acid ester glycidyl ether (SFEGE) is generally carried out under neutral conditions for the grafting of protein. The crosslinking agent is formed by the reaction of sucrose fatty acid ester and epichlorohydrin. The epoxy group can open the ring and combine with amino, hydroxyl, sulfhydryl bond, carboxyl, and tyrosine phenolic hydroxyl. Under certain temperature conditi...
