Problems solved by technology

[0004] However, when the polyester fiber is heated, the polyester fiber is easy to soften, resulting in lower strength and a greater impact on the tensile properties. When the heat is severe, it may even melt, decompose, and burn. Due to the limitations of the material, it has a certain The phenomenon of molten dripping is likely to cause secondary harm, which greatly limits its use

Embodiment 1

[0047] see figure 1 , a preparation process of tensile-resistant polyester fiber industrial yarn, comprising the following steps:

[0048] S1, crush the polyester material to form a master batch, and heat it at a high temperature to obtain a molten master batch for use;

[0049] S2. Spin the molten masterbatch through the spinning assembly to obtain fiber filaments. First, the fiber filaments are pretreated. The pretreatment of the fiber filaments is as follows: uniformly pass the fiber filaments through the magnetorheological fluid, so that part of the magnetorheological fluid is in the The liquid is hung on the fiber to make the fiber magnetic;

[0050] S3, see figure 2 , the arrow in the figure indicates the moving direction of the fiber, and then the pretreated fiber is evenly moved to the right, and a hot air coating treatment is performed at the same time. Move, and make the attached ball fiber attach to the fiber filament, so as to form a layer of droplet wrapping l...

Embodiment 2

[0057] The coated magnetic ball 2 is wrapped with magnetized water, and the coated magnetic ball 2 is made of a hot-melt material. In the subsequent heat setting operation, the coated magnetic ball 2 is heated and melted and dripped to make its inner magnetization. Water is lost, thereby realizing demagnetization. The end of the anti-droplet staple fiber 1 extends into the coated magnetic ball 2 and contacts with the magnetized water. Due to the water absorption of natural fibers, the anti-droplet short fiber 1 gradually absorbs the coated magnetic ball 2. The inner magnetized water makes the anti-droplet staple fibers 1 gradually have magnetic properties, so that there is a certain adsorption force between multiple anti-droplet short fibers 1, and at the same time, the entire anti-droplet short fibers 1 can be adsorbed with the surface of the fiber filaments, and then A plurality of anti-droplet staple fibers 1 are brought close to each other to change their loose state, so th...

Abstract

The invention discloses a preparation process of tensile-resistant polyester fiber industrial yarn, belonging to the field of polyester fibers. The ball fiber moves toward the fiber filament, and forms a layer of droplet wrapping layer on the surface of the fiber filament. Compared with the prior art fiber industrial yarn, when heated, due to the wrapping of the droplet wrapping layer, its strength is significantly improved, The tensile strength is improved when heated. When the heating is serious and causes combustion, the attached droplet wrapping layer will be burned first, and ash will be produced. It can effectively reduce the fluidity of molten droplets and effectively inhibit the molten droplet phenomenon of the polyester fiber industrial yarn, thereby effectively reducing the potential safety hazards caused by secondary hazards and expanding the scope of use.

Description

technical field [0001] The invention relates to the field of polyester fibers, and more particularly, to a preparation process of a tensile-resistant polyester fiber industrial yarn. Background technique [0002] Polyester fiber, commonly known as "polyester". It is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dihydric alcohol, referred to as PET fiber, which belongs to polymer compound. Invented in 1941, it is currently the largest variety of synthetic fibers. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery. It is durable, wrinkle-resistant, iron-free, and non-sticky. [0003] Polyester fiber has the advantages of high modulus, high strength, high elasticity, good shape retention and heat resistance, and has become the most widely used and consumed fiber variety. [0004] However, when the polyester fiber is heated,...
