Problems solved by technology

[0004] However, aramid fiber has the following problems: 1. Aramid fiber is very fluffy and has poor cohesion, so that the sliver is easy to block the bell mouth
2. Aramid fiber is very easy to generate static electricity, and it is easy to produce the phenomenon of sticking rolls, winding rollers, and wrapping rollers, which affects the spinnability of aramid fibers

Embodiment Construction

[0056] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0057] The invention uses aramid fibers to produce high-strength tube-packed twisted yarns.

[0058] The selection of raw materials and production line equipment is as follows:

[0059] Aramid fiber: breaking strength 190CN / tex, breaking stress 2.76GPa, elastic modulus 44N / tex, breaking elongation 4%, linear density 2.2dtex, length 51mm, moisture regain 7.0%.

[0060] The aramid fiber production line adopts A002C automatic plucking machine → A035C mixed opener → A036B porcupine opener → A092A double cotton box feeder → A076C lapping machine → A186 carding machine → FA317 drawing frame → FA411 Roving frame→DTM169 spinning frame→21C~S winding machine→1381 doubling frame→A631 twisting frame→1332M winding machine.

[0061] The specific steps of production are as ...

Abstract

The invention belongs to the technical field of textiles, and specifically relates to a process for producing high-strength twisted yarn from aramid fibers and its products, which are: aramid fibers are cleaned, carded, drawn, roving, spun, wound, and combined , Twisting, and winding processes produce high-strength packaged twisted yarn. The twisted yarn produced by the present invention has the advantages of high strength, high wear resistance, high temperature resistance, flame retardancy, good softness resistance, low shrinkage, stable chemical structure, no molten droplets when burned, no poisonous gas, etc., and has a wide range of applications.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a process for producing high-strength twisted yarn from aramid fiber and its products. Background technique [0002] Aramid fiber is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, insulation, anti-aging, and long life cycle. It is widely used in composite materials, bulletproof Products, building materials, special protective clothing, electronic equipment and other fields. [0003] As a new type of high-tech synthetic fiber, aramid fiber has some excellent characteristics: First, aramid fiber has good mechanical properties. Its breaking strength is higher than that of ordinary polyester, cotton, nylon, etc., with large elongation, soft hand feeling and good spinnability. It can be produced into short fibers and filaments of different ...
