Problems solved by technology

The raw materials of traditional silk non-woven fabrics are all degummed and then non-biologically active non-woven fabrics are produced through the spunlace production process, and the removal of sericin not only produces waste, but also produces wastewater that seriously pollutes the environment
If there is no degumming treatment process, the silk is easy to dissolve and stick when it meets water, and harden and harden after drying, which is not conducive to processing
Since the degummed silk non-woven fabric has no biological activity and high cost, it has no health care and nutritional effects when used as women's sanitary napkins, beauty and skin care masks, and medical cloths.

Embodiment 1

[0021] Weigh 10 kg silkworm cocoon silk, remove impurities, put it into the refining pool and soak it fully with clean water, pick it up and dry it in the drying room, set the temperature at 80°C, and dry it; then soak it again, and then dry it. Repeat 2 times. Then put it into 0.5% Turkish red oil solution and soak until soft, take it out, put it into a normal temperature alkaline solution with PH=8.5 and hydrogen peroxide content of 1% and soak for 10 hours, turn it once an hour, wash after soaking, dehydrate, and dry. Dry at 70°C; then, comb the dried cocoon silk with a carding machine, and shorten it into short fiber filaments with an average length of 3 cm; use the obtained short fiber cocoon silk as the raw material of the spunlace production line, Adjust the baking temperature in the spunlace process to 70°C for carding, web laying, and spunlace production to obtain silk denatured non-woven fabrics rich in sericin. The obtained silk denatured non-woven fabric is used a...

Embodiment 2

[0023] Weigh 15 kg of castor silk, remove impurities, put it into the refining pool and soak it fully with clean water, pick it up and dry it in the drying room, set the temperature at 100 ° C, and dry it; then soak it again, dry it again, repeat Do this 4 times. Then put in 2% softener KC or softener SCM or softener NDS or softener SD or softener DMD solution to soak until soft, take it out, put it into a normal temperature alkaline solution with PH=8.5 and hydrogen peroxide content of 2%. 12 hours, turning once an hour, washing after soaking, dehydration, and drying at 80°C; then, combing the dried cocoon silk with a carding machine, and shortening it into short fibers with an average length of 3 cm; The obtained short fibrous cocoon silk is used as the raw material of the spunlace production line, and the baking temperature in the spunlace process is adjusted to 80°C for carding, web laying, and spunlace production to obtain silk denatured non-woven fabrics rich in sericin ...

Embodiment 3

[0025] Weigh 8 kg of cocoon silk, remove impurities, put it into the refining pool and soak for 2 hours, the sulfuric acid solution in the pool is PH=2, 98 kg, dehydrate after soaking; put the dehydrated cocoon silk into the glutaraldehyde solution for soaking After 10 hours, this solution can also be formaldehyde or monoaldehyde solution, the concentration is 2%, the sulfuric acid is adjusted to PH=2, and dehydration is carried out after soaking; the cocoon silk after dehydration is put into PH=10 again, the hydrogen peroxide content is 1% Soak in alkaline solution for 10 hours, wash after soaking (bleaching), dehydrate, and dry at a temperature of 40°C to 80°C; comb and shorten the dried cocoon silk with a carding machine to an average length of 4 cm In the form of short fibers, adjust the baking temperature in the spunlace process to 50°C for carding, laying, and spunlace production to obtain silk denatured non-woven fabrics rich in sericin. The obtained silk denatured non-...

Abstract

The invention relates to silk property-variable non-woven cotton with sericin and relative application. Said silk property-variable non-woven cotton via selection-modifying-blanching, and washing-carding-needling processes can be made into the silk property-variable non-woven cotton which will not lose silk. Said non-woven cotton can recover water-solubility and biological activity via protein recover treatment to supply the health function of silk protein, and apply the medical, hairdressing and daily consumption areas. Since said invention can keep a lot of sericin protein, therefore, it has lower cost, better fiber flexibility and thermal insulation than traditional silk non-woven cotton, and it can avoid de-gumming process to reduce environment pollution with better economic, social and zoology benefits

Description

technical field [0001] The invention belongs to the field of silk spinning, and in particular relates to a silk denatured nonwoven fabric containing sericin and its application. Background technique [0002] Under the influence of some external factors, the physical and chemical properties of proteins change, and the phenomenon of loss of biological activity is called protein denaturation. When the environmental conditions are restored, some of the biological activity of the protein is also restored, which is the renaturation of the protein. Silk is a natural protein fiber, mainly composed of silk fibroin and sericin, of which sericin can account for 10% to 40%. Silk fibroin is insoluble in water, while sericin is soluble in water, and its protein molecules have a large number of hydrophilic side groups. Sericin is composed of 18 kinds of amino acids, which have health care and nutrition effects on the human body. Spunlaced non-woven fabric is a kind of non-woven fabric, ...
