What are the characteristics of pure silk fabric? It's actually cool. The following is nothing but to turn, said more academic. In a word, silk fabrics through, other fabrics are basically BS, especially in summer.
Features of silk fabrics:
Pure silk fabric features one, comfortable. Is silk protein fiber, has good biocompatibility with human body, combined with a smooth surface, to the human body is all types of fibre in terms of its friction coefficient is the lowest, only 7.4%. Therefore, when our delicate skin and silks want to meet, there will be unique softness, according to the curve of the human body, so safe and considerate of our every inch of skin.
Silk fabric features two, moisture absorption and release. Enrichment of silk amino (- CHNH) number of fibrous protein, the amino group (NH2) and hydrophilic group, also due to its porosity, easy to water distribution, so it can absorb the moisture in the air or water supplies, and keep a little bit of water. Under normal temperature, it can help the skin maintain a certain amount of moisture, do not make the skin too dry, summer clothes, again sweat and inhibit the body heat to send out quickly, let a person feel very cool. It is this property that is more suitable for direct contact with human skin, so that we can use it as clothing, not only beautiful but also comfortable.
Silk is not only a better heat dissipation and insulation. It is insulated in its porous structural fiber. In silk fibers, there are many very fine fibers. Therefore, the appearance of solid 38% silk is actually hollow, among which there is a large gap to prevent the heat distribution of air, so that silk has a good thermal insulation.
Silk fabric features three, heat - resistant sound - absorbing, dust - proof. Silk fabrics have larger porosity, have good sound-absorbing, and this is why, in addition to clothing production, as well as indoor decoration like silk carpet, tapestry, curtain, wallpaper and other decorative silk room set up, can not only reduce the dust in the house, also can maintain its quiet room. Because silk has hygroscopic, dehumidifying and moisture-proof properties, suction resistance and porosity, it can adjust temperature, and also can absorb harmful gases, dust and microorganisms.
In addition, it is a relatively heat - resistant fiber. It is heated to 100 ℃, only 5-8% of the vulnerable, 4 to 5 times that of rayon thermal changes of high level. Silk combustion temperature is 300 ~ 400 ℃, is a kind of flame retardant fiber, combustion synthesis temperature at 200 ~ 200 c, which is flammable, easy to melt. Therefore, as the raw material of interior decoration, silk fiber can not only play the role of sound insulation, dust prevention, thermal effect and characteristics of flame retardant.
Pure silk fabric features four, anti - ultraviolet. Tryptophan in silk protein, tyrosine can absorb ultraviolet ray, with silk has good anti - ultraviolet ray. Ultraviolet radiation is very harmful to human skin. Silk, of course, is chemically altered to absorb ultraviolet light, so it tends to turn yellow in the sun.
