Sports goods field Aramid Polyester DTY Yarns is used to make golf clubs, tennis rackets, bows and arrows, sleds and other sports goods.5 times that of glass fiber and 5 to 6 times that of steel; the tensile modulus is 2 to 3 times that of steel wire and glass fiber; the toughness is 2 Times. In the aerospace field, aramid is not only used in fairings, wings, emergency exit system components, bulkheads, bulkheads, etc. It is a high-strength, high-modulus, low-density, and wear-resistant organic synthetic high-tech fiber. Excellent flame retardancy Aramid has a limiting oxygen index (LOI) greater than 28, so it will not continue to burn when it leaves the flame. It is the world's top three high-tech fibers. Civil industrial fields tires, brake pads, clutches, automobile bodies, high-strength ropes, etc. 1, has good mechanical properties has high specific strength and specific modulus.
After 100 times of washing, the tear strength of the aramid fabric can still reach more than 85% of the original strength. During the friction process, the aramid fiber plays a role in improving the stability of the friction coefficient, reducing wear, and also reducing the wear of the material on the opposite side of the friction. Among them, the tensile strength of para-aramid is equivalent to that of carbon fiber, which is about 1.
The polymerized chain segment is relatively regular, with good high temperature resistance, strength and high modulus. Construction field aramid fiber can replace asbestos for reinforced cement, used in light structure, high strength components, and prevent the cracking of cement products, improve the seismic resistance of buildings. The functional group on the monomer is meta-position. 4. 2. 5.. After finishing,
it can meet the requirements of protective clothing in different fields. It has large elongation, soft hand feeling and good spinnability. It can be made into different yarns and woven into fabrics and non-woven fabrics. Good thermal stability can be used continuously under the condition of 205 ℃, can maintain high strength under high temperature conditions above 205 ℃, have a higher decomposition temperature, and will not melt or melt drops under high temperature conditionsAlso See: High Strength, Polymerized Chain, High Temperature, Chain Segment, Strength, High, Aramid
