Preparation method of sericulture fiber material

Abstract

The invention discloses a preparation method of a sericulture fiber material. The method comprises the following steps: (1) drying and crushing mulberry branches to obtain mulberry branch powder; mixing the mulberry branch powder and ion liquid to obtain a mixed solution, preserving the heat, adding additives, and stirring and heating; (2) uniformly mixing degummed silk fibers and ion liquid mixed solution, and heating; (3) mixing products of the step (1) and the step (2), heating and uniformly stirring, and facilitating the reaction; (4) washing an acquired sample by utilizing a renewable reagent, and drying solids to obtain the sericulture fiber. The sericulture fiber has characteristics of good water retention property, high heat stability, antibacterial property and environmental protection, has rigidness of the mulberry fiber and the flexibility of the silk fiber on the aspect of the physical performance; on the aspect of the biological performance, the sericulture fiber has characteristics such as smoothness, flexibility of the silk fiber and the permeability and moisturizing property of the mulberry fiber and has no allergen and immunity reaction, and the performance of the sericulture fiber is better than the mulberry fiber and the silk fiber.

Description

technical field [0001] The invention belongs to the field of biochemical industry, and in particular relates to a preparation method of silkworm and mulberry fiber materials. Background technique [0002] Silk fiber is a kind of protein fiber, which is called four natural fibers together with cotton, linen and wool. Its products are soft and elegant in texture, elegant in luster, soft to the touch, gorgeous in appearance, good in air permeability, hygienic and comfortable to wear, and are deeply loved by consumers and known as the "Queen of Fibers". Cocoon silk is mainly composed of silk fibroin and sericin, among which silk fibroin is the main part of cocoon silk, located in the inner layer of cocoon silk, accounting for about 75wt% of cocoon silk; As a protector and adhesive, it is coated on the outside of the silk fiber, accounting for about 25w% of the silk. Silk fibroin is a fibrous protein, insoluble in water, a nitrogen-containing polymer with a molecular weight of ...

AI Technical Summary

Problems solved by technology

The report of using ionic liquid to dissolve and treat silk fibers, but without using NMMO as a composite solvent, the active groups in silk fibers cannot be released

And did not study the reaction of cellulose fiber and silk fiber, did not form composite fiber
