Aramid has excellent heat resistance, flame resistance, high temperature dimensional stability. Particularly conspicuous is its excellent mechanical properties, strength and polyester similar to, wear resistance, good resistance to bending and has excellent characteristics of textile processing, can acupuncture into spun lace non-woven fabric. Aramid fiber 1313 at different temperatures, strong retention rates at different times, including in the dry heat temperature of 250 for 1000 hours under the conditions of its strength retention up to 60%. Aramid fiber 1313 as a functional fiber in high temperature dust filtration industry has an irreplaceable status, but because of the characteristics of molecular structure determines it has some defects. Such as poor resistance to strong acid, high temperature hydrolysis is poor, not in the coal-fired boilers, waste incineration and other industry applications.

The technical data of Aramid needled felt
