Embodiment 1

[0013] The production method of the high-strength super heavy denier nylon 66 fiber of the present embodiment comprises the following steps:

[0014] 1) Using nylon 66 salt solution as raw material, carry out continuous polycondensation in the concentrator;

[0015] 2) Spinning on the spinning box;

[0016] 3) Drafting and winding are carried out on the drafting machine and winding machine.

[0017] The winding method in the winding process is the active winding of the clamp shaft. The winding angle during winding is 15-17 degrees. The tension during winding is 500-550cN.

[0018] After testing, the high-strength super-heavy denier nylon 66 fiber produced in this example has a breaking strength greater than 300N, an elastic deformation of less than 7%, and a product with good dimensional stability.

Abstract

The invention provides a production method for a high-strength super-heavy denier nylon-66 fiber. The production method for the high-strength super-heavy denier nylon-66 fiber comprises the following steps of: (1) performing continuous polycondensation in a concentrator by taking nylon-66 saline solution as a raw material; (2) spinning on a spinning manifold; and (3) drafting and winding on a drafting machine and a winding machine, wherein a winding way during a winding process is a clamp shaft active winding way, a winding angle during the winding process is 15-17 degrees, and the tension during the winding process is 500-550cN. The production method for the high-strength super-heavy denier nylon-66 fiber has the following technical effects that the produced high-strength super-heavy denier nylon-66 fiber is high in strength, high in elasticity and good in impact resistance, abrasive resistance, fatigue resistance and alkali resistance.

Description

technical field [0001] The invention relates to a production method of high-strength super-heavy denier nylon 66 fiber, which belongs to the technical field of chemical fibers. Background technique [0002] High-strength super-heavy denier nylon 66 fiber can be used for high-performance compression rubber fenders, which can play the role of high-strength restraint. However, due to the high density of high-strength super-heavy denier nylon 66 fibers, the large number of single filaments, and the high tension during stretching and winding, production is relatively difficult, and there is no suitable production method at present. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a production method of high-strength super-duty nylon 66 fiber. [0004] The production method of high-strength super heavy denier nylon 66 fiber of the present invention comprises the following steps: [0005] 1...
