The invention provides a fabric post-finishing agent based on a modified silk fibroin solution and a preparation method of the fabric post-finishing agent. The preparation method comprises the following specific operational steps: (1) removing impurities from waste silk, putting the impurity-free waste silk in a sodium bicarbonate solution for boiling and degumming, taking out and wringing out the degummed waste silk, washing with clean water till the greasy feel is eliminated, putting the primarily treated waste silk in the sodium bicarbonate solution again for boiling and degumming, taking out and wringing out the degummed waste silk again, washing again with clean water till the greasy feel is eliminated, putting the secondarily treated waste silk in an oven for drying, so as to obtain degummed silk; (2) putting the degummed silk in a lithium bromide solution for standing and dissolution, taking out the treated silk, and performing cooling, dialysis and concentration to obtain a silk fibroin solution; and (3) adding glycerin and gelatin into the silk fibroin solution, uniformly stirring to form a membrane solution, adjusting the pH value of the membrane solution and then adding glutaraldehyde and chitosan, uniformly stirring, and finally mixing the treated membrane solution with a solvent containing additives, so as to obtain the fabric post-finishing agent. The fabric post-finishing agent obtained according to the preparation method covers the fabric surface in the form of a composite membrane; and the preparation method is beneficial to improvements in the membrane forming property, the ductility and the like of a silk fibroin finishing agent.

The invention relates to a medical composition for a health-care pillow and a silk traditional Chinese medicine cervical vertebra health-care pillow. Silk, silkworm excrement, wild chrysanthemum flower, notopterygium root, calcined magnet, borneol, albizia flower, tuber fleeceflower stem, rhizoma acori graminei, flos caryophylli, sandalwood, keel, oyster, tetrapanax papyriferus, radix angelicae, safflower, radix crotonis crassifolii, ligusticum wallichii, cassia twig, magnolia obavata, rhizoma atractylodis and kudzu root powder are added into a health-care pillow; and when the health-care pillow is used, due to head temperature and pressure of a head, effective components of medicines in the pillow are slowly released to be sucked into a lung and enter blood circulation, so as to be conveyed to a whole body. Medical research and analysis show that mulberry silks have skin-friendly property, heat retention property and air permeability; the content of organic matters in the silkworm excrement is 83.77-90.44% and the silkworm excrement mainly contains leaf essence, pohytol, sitosterol, free amino acid and the like; and therefore, the health-care pillow has the effects of improving eyesight, nourishing eyes, nourishing brain, calming the nerves and the like, and has the effect of removing heat to cool blood when people with strong lung fire use the health-care pillow. Meanwhile, silkworm fibroins are warm in winter and cool in summer, are also comfortable and have the effects of enabling heart and blood vessels to have no load, accelerating sleep, preventing skin diseases and the like.

The invention discloses a phototherapy carpet with skin-friendly performance. The phototherapy carpet comprises a phototherapy carpet body, an optical fiber woven fabric which is arranged on the phototherapy carpet body and is woven by weaving yarns and optical fiber yarns, and a light source box which is connected with one ends of the optical fiber yarns through light transmission optical fibers;the surfaces of the weaving yarns are covered with a skin-friendly layer; the skin-friendly layer is formed by spraying skin-friendly coating on the surfaces of the weaving yarns and then drying. According to the phototherapy carpet with the skin-friendly performance, disclosed by the invention, the optical fiber woven fabric for emitting light is formed by weaving the weaving yarns and the optical fiber yarns; the optical fiber yarns are inserted and woven in the weaving yarns, so that the mechanical property of the optical fiber woven fabric can be enhanced and the cost also can be saved; the skin-friendly layer is formed by spraying the skin-friendly coating on the surfaces of the weaving yarns so that the optical fiber woven fabric has very strong bacterium-inhibition performance andhealth of patients is ensured; the surfaces of the weaving yarns also can be smooth and cool and have a good touch feeling and an aromatic flavor, so that the comfort of the patients in a phototherapyprocess is improved.

The invention belongs to the technical field of artificial leather, and particularly relates to soft wear-resistant silica gel leather and a preparation method thereof. The soft wear-resistant silica gel leather comprises a base material, a middle silica gel layer and a silica gel surface layer. The middle silica gel layer is arranged on the surface of the base material and comprises the following raw materials in percentage by mass of 50%-70% of methyl vinyl siloxane, 0.5%-1% of polymethylhydrosiloxane, 0.1%-0.5% of a platinum catalyst, 3%-10% of phenyl silicone rubber and 20%-45% of fumed silica. The silica gel surface layer is arranged on the surface of the middle silica gel layer and comprises the following raw materials in percentage by mass of 20-30% of methyl vinyl silicone resin, 30-50% of polymethylvinyl siloxane, 20-30% of fumed silica, 0.5-1% of polymethylhydrosiloxane, 0.1-0.5% of a platinum catalyst, 5-15% of matte reinforcing micro powder and 0.1-0.8% of fluorine-containing particles. According to the soft wear-resistant silica gel leather, the phenyl silicone rubber is added into the middle silica gel layer, and the phenyl and the fumed silica are introduced for reinforcement, so that the wear resistance is enhanced.
