Aramid fibers are a class of heat resistant and strong synthetic fibers. They are used in aerospace and military applications and are suitable for ballistic-type bullet-proof clothing and bulletproof composites, bicycle tires and asbestos substitutes. The name is - aromatic polyamide. They are chain-like molecular fibers oriented along the fiber axis, so it can be developed and used.
Aramid flame retardant fabric characteristics:
Aramid fibers can be well combined with other fibers. Such as: aramid + viscose fiber, aramid + cotton and so on. This main feature also created its good use. Can be made into a variety of functional fabrics.
Conventional aramid features include good abrasion resistance, good resistance to organic solvents, non-conductive, no melting point, low flammability, good fabric integrity at high temperatures, sensitive to acids and salts, sensitive to ultraviolet radiation, etc. The Aramid flame retardant fabric in a short time within the high temperature of 300 degrees will not shrink, brittle or melt. About 400 degrees will begin to carbonize, only the release of trace gases, toxicity is almost zero. Because of its outstanding flame retardant, it is widely used in the production of fire clothes.
The properties of para-aramid: para-aramid fibers such as Kevlar and Twaron provide excellent strength properties, high Young's modulus, high toughness, low creep, low elongation of 3.5% Dyeing - usually dyed with stock solution.
