White nylon board, imported black nylon board, gray-black nylon board

Polyamide fiber is a general term for fibers with groups on the macromolecular chain. Commonly used are aliphatic polyester amines. The main varieties are polyamide and polyamide. Our country’s trade names are nylon and nylon. Nylon fiber is mainly filament, and a small amount of short fiber is mainly used for blending with cotton, wool or other chemical fibers. Nylon filaments are widely used in deformation processing to make elastic yarns as raw materials for weaving or knitting. Nylon fiber is generally spun by melt method. The strength of nylon and nylon fiber is ~, high-strength polyester can reach above, the elongation rate is ~, and the elastic recovery rate when stretched is above. It has been measured that the wear resistance of nylon fiber is twice that of cotton fiber and times that of wool. Its fatigue resistance ranks first among all fibers. It is widely used in the processing of socks and other blended products for civilian use to improve the abrasion fastness of the fabric. However, the modulus of nylon fiber is low and the anti-wrinkle performance is not as good as that of polyester, which limits the application of nylon in the field of clothing. The service life of nylon cord is twice that of viscose, and the impact absorption energy is large, so the tire can drive on bad roads. However, due to the elongation of the nylon cord, when the car stops, the tire deforms and produces flat spots, and the car jumps violently at the beginning of the start. . Therefore, it can only be used for truck tires and is not suitable for passenger car tire cords.
The surface of nylon fiber is smooth, and the friction coefficient of the fiber without oil agent is very high. The nylon oil agent is prone to failure after being stored for a long time, and the oil agent needs to be re-added during textile processing.
The moisture absorption of nylon fiber is higher than that of polyester. The moisture regain rate of nylon and nylon under standard conditions is second only to vinylon among synthetic fibers. It has good dyeing performance and can be dyed with acid dyes, disperse dyes and other dyes.
Concept and classification of modified nylon
Modified nylon is a type of engineering plastics. It is a granular product formed by using nylon raw materials as the base material and changing its physical properties. The output of such products is modified and produced according to the different needs of some manufacturers.
Properties Glass transition temperature and melting point, high thermal distortion temperature, high long-term use temperature, wide use temperature range, small thermal expansion coefficient.
Mechanical properties: high strength, high mechanical modulus, low latent degeneration, strong wear resistance and fatigue resistance.
It has chemical resistance, electricity resistance, flame resistance, weather resistance, and good dimensional stability. The output of such products is modified according to the different needs of some manufacturers. Modified nylon generally includes reinforced nylon, toughened nylon, wear-resistant nylon, halogen-free flame-retardant nylon, conductive nylon, flame-retardant nylon, etc. wait. Modified nylon has many properties, so it is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textile and papermaking machinery, etc.
