Advantage

First: comfortable to wear. Silk is composed of protein fiber, which has good biocompatibility with human body, its surface is smooth. Its friction stimulation coefficient to human body is low among all kinds of fibers, only 7.4%.

Second: good absorption dehumidification. Silk protein fiber is rich in many hydrophilic groups such as amino group (- CONH) amino group (- NH2). Because of its porous nature, it is easy to diffuse water molecules, so it can absorb distribute water in the air, maintain a certain amount of water. Under normal temperature, it can help the skin to keep a certain amount of water, to make the skin too dry; in summer, it can also quickly release sweat heat the human body, making people feel cool.

Silk only has good heat dissipation performance, but also has good heat preservation. The thermal insulation is attributed to the porous fiber structure. There are many tiny fibers in the silk fiber, which are composed of even smaller fibers. Therefore, more than 38% of the silk that looks solid is hollow in fact. There is a large amount of air in these gaps, which prevents the heat being dissipated makes the silk have a good warmth preservation.

Third: sound absorption, dust absorption, flame retardant. Silk fabric has a high void ratio, so it has good sound absorption air absorption, so it can be used for interior decoration in addition to making clothing. As silk has hygroscopic dehumidification properties as well as moisture retention, inspiratory porous properties, it can also adjust indoor temperature humidity, absorb harmful gases, dust microorganisms. In addition, the thermal denaturation of silk fiber is small heat-resistant. When heated to 100 ℃, only about 5-8% embrittlement occurs, while the thermal denaturation of most synthetic fibers is 4-5 times larger than that of silk. The combustion temperature of silk is 300-400 ℃, which is a kind of refractory fiber, while that of synthetic fiber is 200-260 ℃, which is flammable fusible. Therefore, using silk fiber as the raw material of interior decoration can only play the role of sound absorption, dust collection heat preservation, but also play the role of flame retardant.

Fourth: UV resistance. Tryptophan tyrosine in silk protein can absorb ultraviolet rays, so silk has better anti ultraviolet function. UV is very harmful to human skin. Of course, when silk absorbs ultraviolet light, it will undergo chemical changes, which makes silk fabrics prone to yellowing under the sun.

Fifth: health care. The health care function of silk fiber can be replaced. It contains 18 kinds of amino acids necessary for human body, which are almost the same as the amino acids contained in human skin, so it is also known as "the second skin". Wearing silk clothes can only prevent ultraviolet radiation, prevent harmful gas invasion, resist harmful bacteria, but also enhance the vitality of skin cells on the body surface, promote the metabolism of skin cells, have a good auxiliary therapeutic effect on some skin diseases.
