We all know that silk has a long history, but we don't know much about the specific advantages of silk. This blog will detail the benefits of silk products.

Firstly: comfortable to wear. Real silk is composed of protein fibers, which has good biocompatibility with the human body. In addition, the surface is smooth, and its frictional stimulation coefficient to the human body is the lowest among all kinds of fibers, only 7.4%.

Secondly: good absorption and moisture release. Silk protein fibers are enriched with many hydrophilic groups such as amine groups (-CONH) and amino groups (-NH2), and because of their porosity, it is easy for water molecules to diffuse, so it can absorb or emit water in the air, and Stay hydrated. Under normal temperature, it can help the skin retain a certain amount of moisture and not make the skin too dry; in summer, it can quickly dissipate the sweat and heat discharged from the human body, making people feel extremely cool. Silk not only has good heat dissipation performance, but also has good thermal insulation. Its thermal insulation benefits from the porous fiber structure. There are many tiny fibers in silk fibers, and these tiny fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a lot of air in these gaps, which prevents the heat from dissipating and makes the silk very warm.

Thirdly: sound absorption, vacuuming, flame retardant. Silk fabric has a high void ratio, so it has good sound absorption and air absorption, so it can be used for interior decoration in addition to clothing. Because silk has hygroscopic, dehumidifying properties, moisture retention, inhalation and porosity, it can also adjust indoor temperature and humidity, and can absorb harmful gases, dust and microorganisms. In addition, the thermal denaturation of silk fibers is small and relatively heat-resistant. When heated to 100 ° C, only about 5-8% will become brittle, while the thermal denaturation of most synthetic fibers is 4-5 times greater than that of real silk. The combustion temperature of silk is 300-400 ℃, which is a flame-retardant fiber, while the combustion temperature of synthetic fiber is 200-260 ℃, that is, it is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play a flame retardant function.

Fourthly: anti-ultraviolet. Tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has better anti-ultraviolet function. Ultraviolet rays are very harmful to human skin. Of course, after silk absorbs ultraviolet rays, it will undergo chemical changes, so that silk fabrics are prone to yellowing under sunlight.

Lastly, health care. The health care function of silk fiber is irreplaceable. It contains 18 kinds of amino acids necessary for the human body, which is almost the same as the amino acid contained in human skin, so it is also known as the "second skin" of human beings. Wearing silk clothes can not only prevent ultraviolet radiation, prevent harmful gases from invading, resist harmful bacteria, but also enhance the vitality of skin cells on the surface of the body, promote the metabolism of skin cells, and have a good auxiliary treatment effect on certain skin diseases.

So, in order to enjoy a higher quality of life, we should choose silk products.
