superiority

First: comfortable to wear. Silk is made of protein fiber, which has excellent biocompatibility with human body and smooth surface, and its friction stimulation coefficient to human body is the lowest among all fibers, only 7.4%.

Second: good moisture absorption and moisture release performance. Silk protein fiber is rich in amino (-CONH), amino (-NH2) and other hydrophilic groups, and because of its porosity, water molecules are easy to diffuse, so it can absorb or release water in the air and keep a certain amount of water. At normal temperature, it can help the skin retain a certain amount of moisture and will not make the skin too dry; When worn in summer, it can quickly release sweat and heat discharged by the human body, making people feel extremely cool.

Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation benefits from the porous fiber structure. There are many tiny fibers in silk fibers, and these tiny fibers are made up of smaller fibers. So the seemingly solid silk is actually more than 38% hollow, and there is a lot of air in these gaps, which prevents the heat from emitting and makes the silk have good warmth retention.

Third: sound absorption, dust absorption and flame retardant. Silk fabric has high porosity, so it has good sound absorption and air absorption performance. Besides making clothes, it can also be used for interior decoration. Because silk has the properties of moisture absorption, moisture release, moisture retention, air inhalation and porosity, it can also adjust indoor temperature and humidity and absorb harmful gases, dust and microorganisms. In addition, silk fiber has little thermal denaturation and is relatively heat-resistant. When heated to 100℃, only about 5-8% is brittle, and the thermal denaturation of most synthetic fibers is 4-5 times greater than that of 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 the raw material of interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant.

Fourth: anti-ultraviolet. Tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has good anti-ultraviolet function. Moreover, ultraviolet rays do great harm to human skin. Of course, after absorbing ultraviolet rays, silk itself will undergo chemical changes, which will make silk fabrics easily yellow under the irradiation of sunlight.

Fifth: medical care. The health care function of silk fiber is irreplaceable. It contains 18 kinds of essential amino acids, which are almost the same as those contained in human skin, so it is also called the "second skin" of human beings. Wearing silk clothes can not only prevent ultraviolet radiation, harmful gas invasion and harmful bacteria, but also enhance the vitality of skin cells on the body surface and promote the metabolism of skin cells. At the same time, it has a good adjuvant treatment effect on some skin diseases.
