Embodiment 1

[0033] A preparation method of expanded silk floss, comprising the steps of:

[0034] (1) Take tussah silk as raw material, after removing impurities and rinsing, add water to soak for at least 30 minutes, the liquor ratio is 15:1; then dehydrate and complete the cleaning; degumming the cleaned silk under high temperature and pressure to obtain a degummed silk fibroin fiber solution ; The pressure of high temperature and high pressure degumming is 0.2MPa, the temperature is 125 ℃, and the degumming time is 15 minutes; the mass concentration of degumming silk fibroin fiber solution is 75%;

[0035] (2) Add the mixed solution of turmeric extract, acetic acid and carboxymethyl cellulose into the degummed silk fiber solution, ultrasonically treat for 2 hours, then add polyurea formaldehyde and selenocystamine hydrochloride, and ultrasonically treat for 1 hour; Then dehydrate and dry to obtain processed silk; the mass ratio of degummed silk fiber, turmeric extract, acetic acid, car...

Abstract

The invention discloses an expanded silk floss sheet and a preparation method therefor. The method comprises the following steps: (1), performing high-temperature and high-pressure degumming of cleaned silk to obtain degummed fibroin fiber solution; (2), adding the mixed solution of a turmeric extractive, acetic acid and carboxymethylcellulose to degummed fibroin fiber solution, performing the supersonic processing for 2-3 hours, adding polyurea formaldehyde and selenocystamine dihydrochloride, performing supersonic processing for 1-1.5 hours, performing dehydration and drying to obtain processed silk; (3), heating the processed silk under the temperature of 180 DEG C for 30 seconds, and heating the processed silk under the temperature of 210 DEG C for 20 seconds to obtain perforated silk,preparing a silk floss sheet through the perforated silk and then performing the dipping of amino polyethylene glycol aqueous solution to obtain a processed silk floss sheet; (4), putting the processed silk floss sheet into a rotatable sealed container with a blasting membrane for puffing, and performing glue spraying and drying to obtain an expanded silk floss sheet. According to the invention,the porous varicosity oak silk sheet with the good wearability is successfully prepared, and the antibacterial property is good, so the method is of positive realistic significance.

Description

technical field [0001] The invention relates to a preparation method of silk floss, in particular to an expanded silk floss sheet and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people are more and more advocating returning to nature. The consumption of pure natural silk quilts has increased sharply, and the consumer market has expanded year by year. The raw materials of silk cotton quilts are all kinds of real silk, among which, silk cotton quilts made of porous expanded silk have better elasticity, warmth retention, softness and other wearing properties than ordinary silk cotton quilts. [0003] Porous bulked silk refers to the silk with a porous structure inside the silk fiber. Because the porous structure can form many small spaces for storing air, it can store a large amount of still air, so it has good warmth retention, and good air permeability and moisture permeability. , has received extensive atten...
