It is heated to 100 ° C, only 5-8% fragile, is a high level of 4 to 5 times the thermal change of rayon. Silk burning The temperature is 300~400 °C, which is a kind of flame retardant fiber. It needs to be burned at a synthetic temperature of 200~2600C, which is flammable and easy to melt. Therefore, as a raw material for interior decoration, the fiber can not only soundproof, dustproof, thermal effect and characteristics. It is flame retardant.
5, anti-UV. Tryptophan in silk protein, tyrosine can absorb ultraviolet light, silk has good anti-ultraviolet radiation. Ultraviolet radiation is very harmful to human skin. Of course, silk absorbs ultraviolet light, its chemical Change, so, under the sun, the silk is easy to turn yellow.
