1.Description of nomex aramid  thread:

Para-armaid thread is fire retardant sewing thread made from 100% Kevlar® or para-aramid continuous filament. This thread offers thermal resistance and protective seam durability in applications exposed to high external heat.

para aramid thread

a. High tensile, high strength ,It is twice as much as filament filament polyester /nylon thread.

b. Flame resistance ,it is one of the best fireproofing material in the world.

c. High temperature resistance , Retains adequate strength even after heat ageing up to 400°C for 30 minutes

d. High chemical resistance, high stability

e. Low thermal expansion rate

f. Low specific gravity

g. Nonconductor of electric,It is one of the best nonconductor material.

h, Low elongation rate, high modulus ,high breaking strength

Weakness:

anti-dissolve anti-combustion just carbonization
