Raw silk is the product obtained after silkworm reeling silk, commonly known as real silk. Chinese silk has a long history, and its modern production ranks first in the world. Then, what is the function of real silk

Good Hygroscopicity and Dehumidifying

Silk protein fiber is enriched with many hydrophilic groups such as amine-CHNH and amino-NH2, and because of its porosity, it is easy to diffuse water molecules, so it can absorb or emit water in the air and maintain a certain amount of water. Under normal temperature, it can help the skin to maintain a certain amount of moisture, not to make the skin too dry. In summer, it can also quickly dissipate the sweat and heat from the body, making people feel cool. It is because of this feature that silk fabrics are more suitable for direct contact with human skin. Therefore, silk clothing is one of the must-have summer clothes.

Silk not only has good heat dissipation performance, but also has good thermal insulation. Its thermal insulation is derived from its porous fibrous structure. There are many fine fibers in silk, and these fine fibers are composed of finer fibers. Therefore, more than 38% of the seemingly solid silks are hollow, and there is a large amount of air in these gaps, which prevents the heat from being emitted and makes the silk very warm.

Sound Absorption and Vacuuming

Silk fabric has a high void ratio, thus it has good sound absorption and air absorption. Therefore, in addition to making garments, they can also be used for interior decoration, such as silk pillowcase, silk carpets, tapestries, curtains, wall coverings, etc,. Decorating rooms with silk not only makes the house clean, but also keeps the room quiet.

Heat Resistance

Silk fibers have low thermal denaturation and are relatively heat resistant. It is only about 5 to 8% embrittled when heated to 100 ° C, and most synthetic fibers are 4 to 5 times more thermally variable than silk. The burning temperature of silk is 300~400°C, which is a kind of flame retardant fiber, while the burning temperature of synthetic fiber is 200~260°C, which is flammable and fusible. Therefore, silk fiber can be used as a raw material for interior decoration with strong heat resistance.

UV Rays Resistance

The tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has a good anti-ultraviolet function. Ultraviolet rays are very harmful to human skin. Of course, after absorbing ultraviolet rays, the silk itself undergoes chemical changes, so that the silk fabric is easily yellowed under the illumination of sunlight.

Health Effects

Real silk is composed of protein fiber, which has excellent biocompatibility with the human body. In addition, the silk surface is smooth, and its friction coefficient to the human body is the lowest among all types of fibers, only 7.4%. Therefore, when our delicate skin contacts with smooth and delicate silk, the silk can safely care for every inch of our skin, which makes us feel comfort.
