preparation example Construction

[0038] Such as figure 1 Shown, the preparation method of antibacterial warm silk cotton sheet of the present invention comprises the steps:

[0039] S1. Providing silkworm cocoons, degumming and dissolving them, performing dialysis treatment, and concentrating after filtration to make silk fibroin solution;

[0040] S2. Weigh the silk fibroin solution in part of step S1, add glycerin therein, mix evenly, and freeze-dry under low temperature conditions to obtain a silk fibroin porous sponge;

[0041] S3. Provide medical stone powder, prepare an aqueous suspension of nanoparticles, and perform cationization treatment on the nano medical stone to obtain a cationized nano medical stone aqueous suspension;

[0042] S4. Weighing the silk fibroin solution in part of step S1, adding the same proportion of glycerin and cationized nano medical stones with different gradient mass ratios to obtain medical stone-silk fibroin-glycerol suspension;

[0043] S5. The medical stone-silk fibroi...

Embodiment 1

[0046] Bombyx mori cocoon shells were put into 0.25% sodium carbonate aqueous solution at a bath ratio of 1:50 (g / mL) and boiled three times for 30 minutes, 30 minutes and 45 minutes. Fully cleaned, finally loosened, and dried in an oven at 60°C to obtain degummed silkworm silk fiber.

[0047] Weigh the degummed silkworm silk fibroin and dissolve it in a 45% ethanol solution containing 30% to 40% anhydrous calcium chloride by mass at a bath ratio of 1:10 (g / mL), and dissolve it at 70°C for 2 hours to obtain silkworm silk prime solution.

[0048] Fill the silkworm silk fibroin solution into a dialysis bag with a molecular weight cut-off of 12.0-16.0kDa, place the dialysis bag filled with the silkworm silk fibroin solution in a container filled with deionized water, and replace it with new deionized water every 2 hours. The water in the container was replaced with water, and the dialysis was continued for 3 days to obtain the purified silkworm silk fibroin aqueous solution. Ad...

Abstract

The invention discloses an antibacterial warm-keeping silk floss sheet and a preparation method thereof. The preparation method comprises the following steps: S1, preparing a silk fibroin solution; S2, preparing fibroin porous sponge; S3, preparing a cationized nanometer medical-stone water suspension; S4, preparing a medical stone-fibroin-glycerin suspension; and S5, enabling the medical stone-fibroin-glycerin suspension prepared in S4 to uniformly permeate the interior of the fibroin porous sponge prepared in S2 in one time or multiple times, and performing freeze-drying processing, so as to obtain the antibacterial warm-keeping silk floss sheet. The antibacterial warm-keeping silk floss sheet contains multiple trace elements, has strong antibacterial function and rapid heating characteristic, is good in warm-keeping property, is capable of efficiently persistently giving play to functions, and can be used to prepared comfortable warm-keeping household textile products with rehabilitation health-care functions.

Description

technical field [0001] The invention relates to an antibacterial and warm silk floss, in particular to an antibacterial and warm silk floss loaded with nanometer medical stone, and a preparation method thereof. Background technique [0002] With the rapid development of the social economy and the acceleration of the pace of work, the proportion of sub-healthy people is getting higher and higher. People's requirements for textiles have developed from the simple covering of the body in the past to the comfort and functionality closely related to health today. . At present, the research on the functionalization of textiles mainly focuses on the far-infrared function and antibacterial function. [0003] For the development of textiles with far-infrared functions, the idea originated from Japan. After that, Russia, Germany, etc. also started the research and development of this technology in the 1980s, especially Japanese products are relatively abundant. The research on far-i...
