What are the advantages of silk?

Silk is a natural protein fiber that has been prepared by silkworm silkworm silkworms and has been carefully compiled.

As we all know, wearing silk in summer is more comfortable. So what are the advantages of silk?

1. Comfort. Silk is composed of protein fibers, has excellent biocompatibility with the human body, and has a smooth surface, and its friction coefficient to the human body is the lowest in all kinds of fibers.

2. Good suction and moisture release. Silk fibroin fibers are rich in many hydrophilic groups such as amine groups (-CHNH), amino groups (-NH2), and because of their porosity, they easily diffuse water molecules, so they can absorb moisture or emit moisture in the air. Keep a certain amount of moisture. Under normal temperature, it can help the skin to retain a certain amount of moisture without making the skin too dry. In summer, it can quickly dissipate the sweat and heat discharged by the body, making people feel very cool.

3. Sound absorption, vacuum, heat resistance. Silk fabrics have a high porosity, and therefore have good sound absorption and inhalation properties, so besides making clothes, they can also be used for interior decoration such as silk carpets. Arranging rooms with silk decorations not only keeps the house dusty, but also keeps the room quiet. Because the silk has hygroscopicity, dehumidification performance and moisture retention, inhalation and porosity, it can also adjust the indoor temperature and humidity, and can absorb harmful gases, dust, and microorganisms. In addition, the thermal deformation of silk fibers is small and relatively heat-resistant. When it is heated to 100°C, it is only about 5 to 8% brittle, and most synthetic fibers have a thermal change of 4 to 5 times larger than silk. The burning temperature of silk is 300~400°C, which is a kind of flame-retardant fiber, and the burning temperature of synthetic fiber is 200~2600C, which is flammable and easy to melt. Therefore, the use of silk fiber as a raw material for interior decoration not only plays a role in sound absorption, vacuum cleaning, heat preservation, but also plays a flame-retardant function.

4. UV resistance. The tryptophan and tyrosine in silk protein can absorb ultraviolet light, so silk has better anti-ultraviolet function.
