Polyamide (PA, commonly called nylon) is developed and produced into injection molding products in the 50 th century so as to replace metal to meet the requirements of light weight and cost reduction of downstream industrial products. The strength of the polyamide fiber is 1-2 times higher than that of cotton, 4-5 times higher than that of wool, and 3 times higher than that of viscose fiber. The polyamide has many repeated amide groups on the main chain, is called nylon when used as plastic, is called nylon when used as synthetic fiber, can be prepared from diamine and dibasic acid, and can also be synthesized by omega-amino acid or cyclic lactam. Polyamide fibers have poor heat resistance and light resistance, poor retention properties, and the resulting garments are not as stiff as polyester. In addition, both of nylon-66 and nylon-6 used for clothing have a disadvantage of poor moisture absorption and dyeing properties, and therefore, new polyamide fibers of nylon-3 and nylon-4, which are new varieties of polyamide fibers, have been developed, and are characterized by light weight, excellent crease resistance, good air permeability, good durability, dyeing properties, heat setting, and the like, and thus are considered to have a promising future.
The nylon is generally prepared by melting raw materials by heating at a temperature higher than the melting point of the raw materials, extruding, cooling, and cutting into fine particles. However, in the prior art, when the nylon is extruded from the mold, the liquid nylon close to the inner wall of the mold tends to adhere to the inner wall of the mold, and the liquid nylon has a certain viscosity, so that the flow rate of the liquid nylon close to the inner wall is slow and the liquid nylon comes out from the middle part of the mold. The liquid nylon that speed differs can lead to the problem that the flow of the liquid nylon of position difference is different when the ejection of compact, finally leads to the ejection of compact inhomogeneous.
