Regenerated silk fiber with alcohols as coagulating bath and method for preparing same

Abstract

This invention is a rebirth silk fibre and preparation method. Silk is broad use because of excellent mechanics capability. But the produce is work force denseness and high cost. This invention take the raw material used high chroma rebirth silk protein water liquor (10-40%) with filature former liquor from industry scrap silk to process wet way filature. And adopt pure compound or multi-pure polymer water liquor to process concreting. This invention have some trait: abroad raw material source, high capability rebirth silk fibre, low cost, blare of nature silk and simple filature process, green environment protecting. In this method, rebirth silk fibre's rupture intention can get 0.1~1.0Gpa and its rupture elongate rate can be 10%-60%.

Description

technical field

[0001] The invention belongs to the technical fields of textile fiber, material science, bionics, and protein chemistry, and specifically relates to a high-concentration regenerated silk protein aqueous solution as a spinning stock solution, and an alcohol compound or polyol polymer and its aqueous solution as a coagulation bath. A high-performance regenerated silk fiber obtained by wet spinning and a preparation method thereof. Background technique

[0002] As an excellent fiber material, natural silk has attracted much attention and has been widely used because of its softness, good air permeability, and comfortable wearing. In recent decades, the application of silk protein in other fields has become increasingly broad, and its scope has involved food, medicine, biotechnology and daily chemical industry. However, the raw material cost of natural silk is relatively high and strictly limited by seasons. At the same time, another natural silk fiber—spider s...
