Silk not only plays its high-quality fiber function in the field of clothing, but also develops various new functional materials through various chemical or physical treatment methods, which broadens the new uses of silk.

1, medical field?

Silk fibroin and sericin are components of spun silk, which can be treated with concentrated sulfuric acid to obtain the same substance as heparin. They have anticoagulant activity and delay coagulation time, and can be used to develop blood testing equipment or antithrombotic materials. By changing some processing conditions in the same way, spun silk rich in water absorption and water retention can be processed into advanced water-based materials or other physiological health care products. In addition, the spun silk is chemically synthesized by polymer, so that calcium or phosphorus can be condensed with the spun silk, and an "orthopedic material" for orthopedic treatment can be developed. Similarly, after chemical treatment, artificial muscles or artificial ligaments can also be developed. Silk fibroin films made of spun silk can also be made into wound protection films for treating burns or other skin injuries.

2. Industrial field

The silk powder processed into particles can be used as an additive for cosmetics or health food, and can also be made into silk paper or food fresh-keeping packaging materials and antibacterial silk materials containing silk powder. Silk fibroin film can be used not only to process contact lenses, but also to mix silk powder as fine as 0.3μm with resin to develop a new product called silk skin. High-grade coatings made by adding silk powder into some coatings can be used to spray furniture supplies, increase the elegant appearance and good touch of utensils, and are widely used in various indoor decorations.

3, natural silk fabric mask, leading the new beauty trend.

The structure of natural silk is very similar to human skin, so it has the reputation of "second skin" of human body. Modern medical experiments further prove that the protein content of silk is much higher than that of pearl, in which the nitrogen content is 37 times that of pearl, and the main amino acid content is as high as 10 times. These amino acids can be directly absorbed and adsorbed by human hair and skin. That is, it is easier to penetrate into the outer layer of human epidermis and accelerate the metabolism of skin. Silk amino acids can also effectively inhibit the production of skin melanin.

Since 2000, with the advocacy of returning to nature and green revolution, silk has attracted more and more attention and pursuit. From expensive silk quilts to silk pillows and underwear, to silk medical sutures and silk artificial skin in the medical field, silk plays an increasingly important role. Nowadays, the beauty industry has set off a wave of silk beauty. Silk cosmetics made of silk have become the first choice for countless women who love beauty.
