Synthetic fibers have a wide range of raw materials and rich and colorful resources. They are not limited by natural green plant resources, and have been extended to very simple and colorful vapors, liquids and minerals. Such as coal, crude oil, gas, etc. are all starting and ending raw materials for synthetic fibers. Take this chemical substance and refine some basic chemical raw materials through organic chemistry solution.

The advantages of nylon are high hardness and good wear resistance. Its hardness and wear resistance rank first among all chemical fibers.

The defect of nylon is the same as that of polyester fabric, and its hygroscopicity and permeability are weak. In a dry natural environment, nylon is easy to cause static induction, and polyester staple fiber textiles are also prone to pilling and fluffing. The high temperature resistance, light resistance and heat resistance of nylon are not good enough, and the ironing temperature should be adjusted below 140℃. In addition, nylon has poor shape-retaining ability, and the clothes and trousers made of it are not as straight as polyester cloth, and are easy to deform. But it can be carried around and attached, and it is a good raw material for making all kinds of body shirts.

1. Acrylic fiber: Acrylic fiber is the product name in China, and its alias is polythiophene chemical fiber.

The appearance of acrylic fiber is milky white, rolled, bulky, soft to the touch, and looks like wool. It is mostly used for blending with wool or as a substitute for wool, so it is also called "generated wool".

The hygroscopicity of acrylic fiber is not good enough, but its lubricity is better than that of wool and silk chemical fiber. Its wear resistance is weaker among synthetic fibers, and the ironing temperature of acrylic chemical fibers is below 130 °C.

Vinylon is as white as snow and soft like cotton, so it is often used as a substitute for pure natural cotton wool, which is called "generated cotton wool". The hygroscopicity of vinylon is better than that of synthetic fibers. In addition, vinylon has good wear resistance, light resistance and corrosion resistance.

2. Chlorine: The alias of Chlorine is polyethylene chemical fiber.

Chlorine has many characteristics, strong solvent corrosion resistance; heat transfer is worse than wool, so it has strong thermal insulation; high electrical insulation performance and flame retardant. In addition, it has the distinct advantage that underwear woven from it can heal rheumatoid arthritis or other pains without irritating or damaging the skin. The disadvantages of vinyl chloride are also very obvious, that is, the deviation of temperature resistance.
