Silk sound-absorbing, dust-absorbing, flame-retardant

Silk fabric has a high porosity, so it has good sound absorption and air absorption, so in addition to making clothing, it can also be used for interior decoration. Because silk has moisture absorption, moisture release properties, moisture retention, air absorption 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 fiber is small, and it is relatively heat-resistant. When heated to 100°C, only about 5-8% embrittlement, while the thermal deflection of most synthetic fibers is 4-5 times larger than that of silk. The burning temperature of silk is 300-400℃, which is a flame-retardant fiber, while the burning temperature of synthetic fiber is 200-260℃, which is flammable and easy to melt. Therefore, the use of silk fiber as a raw material for interior decoration can not only play a role in sound absorption, dust absorption, and heat preservation, but also play a flame retardant function.
