Embodiment 1

[0081] Using silkworm raw silk, after cooking silk, silk melting, dialysis, concentration, etc., to prepare fresh silk protein solution, the specific steps are as follows:

[0082] Weigh 250 grams of domestic silkworm silk raw silk, cut the silk fibers, and each section has a length of about 15 centimeters. Heat 100 liters of pure water with an electric heating tank, slowly add 212 grams of anhydrous sodium carbonate when it is close to boiling, stir evenly, continue heating until boiling, then put in raw silk, start timing when all raw silk is submerged in water, and stir every 7 minutes Once, take it out after 30 minutes. Put the degummed silk into the washing machine, set the rinsing program, wash it twice with pure water, put the dehydrated degummed silk into the blast drying box, and dry it for 12 hours to 18 hours.

[0083] Prepare 9.3M lithium bromide solution, according to the bath ratio of degummed silk and lithium bromide solution 1 / 4, add degummed silk, dissolve in...

Embodiment 2

[0085] A kind of silk protein coating solution, is made up of 0.9g of silk protein, 100g of phenylethyl alcohol, cross-linking agent Vimtex EL-28g, surfactant (Tween-80) 1g, hygroscopic skin care ingredient (glycerin) 100g and water 800g, specifically The preparation method is as follows:

[0086] (1) Mix the surfactant (Tween-80) with the hygroscopic skin care ingredient (glycerin) and phenylethyl alcohol in a volume ratio of 1:1:1, and stir at 5000r / min for 5min to obtain the mixed solution A, which is white .

[0087] (2) Mix the mixed solution A prepared above with the freshly prepared silk protein solution B (concentration: 5wt%) in Example 1 according to the volume ratio of 1:5, mix and stir evenly to obtain the silk protein coating stock solution.

[0088] (3) Dilute 1L of the silk protein coating solution prepared above by 50 times, add 10g of Vimtex EL-2 crosslinking agent (name: Vimtex EL-2, SDS: S-50003, manufacturer: Suzhou Weiming Chemical Industry Co., Ltd.) . ...

Embodiment 3

[0090] A kind of fibroin coating solution suitable for polyester chemical fiber fabrics consists of 0.6g of fibroin, 100g of phenoxyethanol, 5g of crosslinking agent Vimtex EL-2, 0.5g of surfactant (Tween-80), hygroscopic skin care ingredients ( Sunflower oil) 100g and water 850g form, and concrete preparation method is identical with embodiment 2.

Abstract

The invention relates to a silk protein coating solution and application thereof in surface modification of fibers or fabrics. A silk protein surface modified fabric with the similar natural real silk effect, which is prepared by the invention, is obtained by finishing the silk protein textile coating solution in a setting and finishing link, wherein the silk protein textile coating solution mainly comprises silk protein, a structure inducer and water. The chemical fiber fabric or the non-natural real silk type natural fabric subjected to surface modification by using the silk protein in the silk protein-containing textile coating solution not only has the similar natural real silk effect and the functions of protecting the skin, resisting aging and the like, but also meets the daily wearing and washing stability requirements.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a silk protein coating solution and its application in fiber or fabric surface modification. Background technique [0002] In recent years, with the continuous improvement of people's living standards, silk has gradually attracted the attention of consumers due to its good biocompatibility, wearing comfort and gorgeous appearance, and the average annual sales of similar products have shown a linear increase. However, on the one hand, due to limited production capacity and cumbersome subsequent processing techniques, it is far from meeting the supply and demand of the consumer market, and its price has remained high; on the other hand, due to the poorer mechanical properties of silk itself than synthetic fibers, Textiles made from silk are often damaged, broken and have holes, and the maintenance cost of silk products is high. Therefore, whether it is the production capacity lim...
