Basic knowledge of nylon 66 production

Nylon production process

It belongs to the direction of organic chemical intermediates or chemical fibers.

Nylon 66 belongs to chemical fibers, polyamides, nylons, man-made fibers, etc., I don't know what you are asking.

SHEMAR Group, formerly known as Pingdingshan Nylon Cord Fabric Factory, is the first modern enterprise in China to produce high-quality skeleton materials for rubber tires - nylon 66 impregnated cord fabric, which was completed and put into operation in 1981 with complete sets of equipment and technology from Japan. The company has 17,000 employees and 17 wholly-owned subsidiaries, holding subsidiaries and joint-stock companies, among which the holding subsidiary Shenma Industrial Co., Ltd. is the first listed company in Henan Province to be listed on the Shanghai Stock Exchange. From 1981 to the end of 2005, when the cord fabric production line was put into operation, SHEMAR Group has achieved a total sales revenue of 30.6 billion yuan, realized profits and taxes of 4 billion yuan, earned foreign exchange from exports of 500 million US dollars, and developed its asset scale from the initial 100 million yuan to the current 8.8 billion yuan.

At present, the annual production capacity of nylon 66 cord fabric and industrial yarn is 100,000 tons, 200,000 tons of nylon 66 salt, 10,000 tons of engineering plastics, 200,000 tons of caustic soda and 200,000 tons of resin, 1 million sets of rubber tires, spinning, printing and dyeing fabrics, carpet silk, thermoelectric and other products also have a certain production scale, and has formed an industrial cluster with nylon 66 salt, cord fabric (industrial yarn), chlor-alkali chemical industry and engineering plastics as the four pillars and related diversification. Among them, the production scale of nylon 66 cord fabric (industrial yarn) ranks first in the world, and the scale of nylon 66 salt ranks first in Asia.

1. The fourth in the world, the scale of nylon 66 engineering plastics ranks first in the country and fourth in the world.

The strength of industrial yarn is generally higher than that of civil wire, which is mainly used for cord fabric, water cloth, industrial cable, etc., and can also be used for industrial purposes such as automobile airbag wire, focusing on safety, wear resistance, and tensile resistance. The main use of civil silk in the civil textile industry, the main concern is the dyeing macro spike debate, the comfort of blending, and the pursuit of more silk structure.

Taking Cixi China Golden Wheel Group as an example, they have a one-stop production line of polymerization and dipping. That is, the crystalline nylon 66 salt or 50% nylon 66 salt water solution is used as raw material to produce nylon 66 impregnated cord fabric.

The production process is described at:

However, they are generally purchased (or imported) directly from nylon manufacturers, and it is quite difficult for you to sell a small amount of caprolactam, unless you represent a large company.

Large manufacturers buy raw materials directly and process them step by step from the raw materials.

If you want to sell, you still have to find a cord fabric factory.

These cord fabrics factories have a large number of machines for spinning yarn.

The company provides modified engineering plastics, mainly nylon PA66, PA6, PP, PC, PBT, PE, ABS, PC ABS, etc.

Chinese trade name for polyamide 6 (polycaprolactam) fiber. Also known as nylon 6. The main varieties of polyamide fibers are aliphatic polyamide fibers, which are divided into two categories:

One is polymers made from polymerization of - amino acids or lactams, such as nylon; The other type is a polymer obtained by the polycondensation of dibasic amines and diacids, such as polyamide 66 (also known as nylon 66).

Nylon 66 melting point 255 260, softening point about 220; The melting point of nylon is 215 220, and the softening point is about 180. The density of the two is the same (g cm 3), and other properties are also similar, such as high strength, good resilience, abrasion resistance is the highest among textile fibers, multiple deformation resistance and fatigue resistance are close to polyester and higher than other chemical fibers, have good moisture absorption, and can be directly dyed with acid dyes and other dyes. Their main disadvantages are poor light and heat resistance and a low initial modulus.

The addition of lightfastness and heat stabilizers to polymers can improve their lightfastness and heat resistance. Nylon has a wide range of uses, filament can be used to make socks, underwear, shirts, sweatshirts, ski shirts, raincoats, etc.; Staple fibers can be blended with cotton, wool and viscose fibers to make the blended fabric have good abrasion resistance and strength. It can also be used as velcro, carpet, decorative cloth, etc.; In industry, it is mainly used to manufacture cord fabrics, conveyor belts, fishing nets, cables, canopy sails, etc.
