Aramid fiber blended yarn and preparation technology thereof

Abstract

The invention relates to the field of textile production, in particular to aramid fiber blended yarn and a preparation technology thereof. The aramid fiber blended yarn is characterized in that 1414.Kevlar aramid fiber, 1313.T450 aramid fiber, flame retardant glue, modacrylic, combed cotton, conducting fiber, chinlon and tencel are adopted as raw materials, fineness degrees of the materials are respectively 1.7, 2.2 and 3 deniers, any four materials in the raw materials are selected as main raw materials, the length of the four materials selected as the main materials at will is 48-51 millimeters, the lengths of the remaining auxiliary raw materials are respectively 28 millimeters and 38 millimeters. Compared with the prior art, the processing technology is simple in process, produced products have good performance such as high strength, high modulus, high-temperature resistance, acid resistance, alkali resistance and light weight, are high in strength, and can solve the problem that a machine part is damaged easily. The development of the aramid fiber blended yarn and the success of matched military supplies can bring markets for enterprises and innovation conceptions. Meanwhile, firmness, flame-retarding performance and anti-static electricity capacity of the military supplies are changed in nature compared with prior fiber blended yarn.

Description

technical field [0001] The invention relates to the field of textile production, in particular to an aramid fiber blended yarn and a preparation process thereof. Background technique [0002] Aramid fiber is by far the most promising fiber among high-performance fibers in the world. Due to the high technical difficulty, only companies such as DuPont of the United States and Teijin of Japan carried out industrial production in the past. The product is widely used in the aerospace and defense industries, and its manufacturing techniques are kept secret. my country is completely dependent on imports of this product. After four consecutive five-year plans were included in the national "863" plan, it was finally successfully tackled and put into industrial production in recent years. [0003] Aramid fiber is a new type of high-tech synthetic material, mainly divided into 1414 Kevlar aramid and 1313.T450 aramid. It has excellent properties such as ultra-high strength, high mod...

Problems solved by technology

However, there are large differences between the materials used for blending cotton, such as: fiber thickness, length, color, and ratio are very different, it is difficult to mix evenly, and the spinnability of aramid fiber itself is poor, easy to entangle; high strength, vulnerable parts, etc. problem, therefore, we must creatively complete the matching production preparation process
