preparation example Construction
[0025] The invention provides a kind of preparation method of silkworm and mulberry fiber material, and preparation process is as follows figure 1 shown, including the following steps:
[0026] (1) Take mulberry branches, wash, dry, and crush to obtain mulberry branch powder, mix and dissolve the obtained mulberry branch powder with the ionic liquid mixture, keep it warm at 40°C to 95°C, then add additives, stir and heat treatment, and obtain product A ;
[0027] (2) Mix the degummed silk fiber and the ionic liquid mixture evenly, heat treatment to obtain the product B,
[0028] (3) Mix the product A and product B obtained in steps (1) and (2), heat and stir at 40°C to 95°C to react evenly, and obtain a sample;
[0029] (4) adding the sample obtained in step (3) to a fiber regeneration reagent to wash and remove the liquid reagent in the sample, recovering the ionic liquid in the liquid reagent, and obtaining the silkworm fiber after the solid is freeze-dried.
Embodiment 1
[0032] Example 1 Preparation of ionic liquid mixture ([EMIM][DEP] mixture).
[0033] Mix 5g of ionic liquid [EMIM][DEP] and 5g of NMMO uniformly, and heat with magnetic stirring at 90°C to obtain an ionic liquid mixture.
Embodiment 2
[0034] Example 2 Preparation of ionic liquid mixture ([EMIM][DEP] mixture).
[0035] Mix 5g of ionic liquid [EMIM][DEP] and 4g of NMMO evenly, add 1g of water, and heat with magnetic stirring at 90°C to obtain an ionic liquid mixture.

Abstract
The invention discloses a preparation method of sericulture fiber material, which comprises the following steps: (1) taking mulberry branches, drying and crushing to obtain mulberry branch powder; taking the mixed solution of mulberry branch powder and ionic liquid, keeping it warm, adding additives, stirring and heating (2) take degummed silk fiber and ionic liquid mixed solution, mix uniformly, and heat treatment; (3) mix the product obtained in steps (1) and (2), heat and stir to react evenly; (4) obtain The sample is washed by adding regeneration reagent, and the solid is dried to obtain silkworm mulberry fiber. The silkworm fiber obtained by the present invention has the characteristics of good water retention, high thermal stability, antibacterial, and environmental protection. In terms of physical properties, the fiber has the rigidity of mulberry fiber and the flexibility of silk fiber; in terms of biological performance, it has the silkiness of silk fiber. It has the characteristics of smoothness and flexibility, and the breathability and moisturizing characteristics of mulberry fiber. It has no allergens and no immune reaction, and its performance is better than that of mulberry fiber and 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 ...
