Advantage
1. Comfortable to wear. Silk is composed of protein fibers and has good biocompatibility with the human body. In addition, its surface is smooth, and its frictional stimulation coefficient to the human body is the lowest among all types of fibers, only 7.4%.
2. Good moisture absorption and release properties. Silk protein fiber is enriched with many hydrophilic groups such as amine groups (-CONH) and amino groups (-NH2). Because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit moisture in the air, and Stay hydrated. Under normal temperatures, it can help the skin retain a certain amount of moisture and prevent the skin from being too dry; when worn in summer, it can quickly dissipate sweat and heat discharged from the human body, making people feel extremely cool.
Silk not only has good heat dissipation properties, but also has good warmth retention properties. Its thermal insulation properties are due to its porous fiber structure. There are many very fine fibers in silk fiber, and these fine fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow. There is a large amount of air in these gaps, which prevents the dissipation of heat and makes the silk have good warmth retention properties.
3. Sound-absorbing, dust-absorbing, flame-retardant. Silk fabric has a high porosity, so it has good sound absorption and air absorption. Therefore, in addition to making clothing, it can also be used for interior decoration. Because silk has moisture absorption and release properties, as well as moisture retention, breathability and porosity, it can also adjust indoor temperature and humidity, and absorb harmful gases, dust and microorganisms. In addition, silk fiber has small thermal degeneration and is relatively heat-resistant. When heated to 100°C, it only embrittles by about 5-8%, while the thermal deformation of most synthetic fibers is 4-5 times greater than that of real silk. The burning temperature of silk is 300-400℃, which is a flame-retardant fiber, while the burning temperature of synthetic fiber is 200-260℃, which is flammable and fusible. Therefore, using silk fiber as a raw material for interior decoration can not only play the role of sound absorption, dust collection, heat preservation, but also have flame retardant function.
4. Anti-UV. The tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has good anti-ultraviolet function. Ultraviolet rays are very harmful to human skin. Of course, after silk absorbs ultraviolet rays, it will undergo chemical changes, making silk fabrics prone to yellowing under sunlight.
5. Health care. The health-care function of silk fiber is irreplaceable. It contains 18 kinds of amino acids necessary for the human body, which are almost the same as those contained in human skin. Therefore, it is also known as the "second skin" of human beings. Wearing silk clothes not only prevents ultraviolet radiation, prevents the intrusion of harmful gases, and resists harmful bacteria, but also enhances the vitality of skin cells on the body surface, promotes the metabolism of skin cells, and has a good auxiliary treatment effect on certain skin diseases.
Disadvantages
It wrinkles easily, absorbs easily, is not strong enough, and fades quickly.
