Production method of regenerated fibroin fiber

Abstract

The invention discloses production method and device of regenerated fibroin fiber, belonging to the technical field of textiles. The production method comprises the following steps of: washing silks and then drying, putting the silks into an alkaline solution, hydrolyzing to obtain a regenerated fibroin basic solution, and preparing regenerated fibroin powder after being dried; adding water and stirring the prepared regenerated fibroin powder to obtain regenerated fibroin saturated liquid; mixing the regenerated fibroin saturated liquid, regenerated rubber stock solution and auxiliary agent according to the proportion of 10-50 percent: 85-45 percent: 5 percent, and spinning after being evenly mixed to obtain the regenerated fibroin fiber. In the invention, non-spinning protein materials, such as waste silks, silk leftovers, waste-spinning silks, silk-spinning waste silks, and the like, are adopted as raw materials, and the novel fibroin fiber with excellent performance, health and comfort is then generated by adopting a wet spinning method and matching with viscose glue and the auxiliary agent after the generated fibroin powder is prepared; and the invention solves the secondary utilization problem of waste protein materials.

Description

technical field [0001] The present invention relates to a kind of production method of fiber, more specifically relates to a kind of production method of regenerated silk protein fiber. Background technique [0002] China is the hometown of silk, and silk is China's treasure. my country's cocoon and silk production has a history of more than 5,000 years. Planting mulberry, raising silkworms, reeling silk, and weaving silk are great inventions of the ancient Chinese people, a major contribution to mankind, and a glorious page in the history of world civilization. As a natural fiber with excellent properties, silk has always been used as a high-grade clothing fabric. However, due to the limitation of production, natural silk fibers are limited. Therefore, regenerated silk protein fibers have emerged at the historic moment. At present, the main production process of regenerated silk protein fibers is as follows: using biochemical engineering technology, such as lithium bromide...

Problems solved by technology

[0003] The disadvantages of this process are: firstly, it uses lithium bromide aqueous solution to dissolve silk to obtain silk protein aqueous solution, which is used as spinning stock solution, and then electrospinning, which has high requirements for process steps and equipment, and is easy to be restricted. Large-scale industrial mass production cannot be carried out; the second is that the regenerated silk protein fiber structure obtained by the above-mentioned process is unstable, resulting in poor performance of the product
