A kind of preparation method of high-performance flame-retardant blended fiber

Abstract

The invention discloses a preparation method of a high-performance flame-retardant blended fiber. Nano-ATO and carbon nanotubes are compounded, and the mass ratio of nano-ATO and carbon nanotubes is 1:1-100 to make a two-component nano-conductive agent. , Standby: by weight, 4-11 parts of soybean protein dimethyl sulfoxide solution, 1-5 parts of magnesium hydroxide solution, 1-5 parts of aluminum hydroxide solution, 50-100 parts of polyacrylonitrile dimethyl sulfoxide The solution is mixed with 4-11 parts of polyurethane dimethyl sulfoxide solution to obtain spinning slurry; the present invention first dehumidifies and removes dust through the sponge, and through the setting of the second spring, the sponge has good cushioning properties, which can protect the fibers and simultaneously It is convenient to apply to fibers of different thicknesses. The hot air generated by the heating element is blown into the drying box by the fan to speed up the air flow and improve the drying efficiency. The heating is more uniform and the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of preparation of blended fibers, in particular to a preparation method of high-performance flame-retardant blended fibers. Background technique [0002] Since the advent of chemical fiber, it has developed rapidly and the market has been expanding continuously due to its excellent properties that many natural fibers cannot match. But at the same time, an important common feature of their existence is also exposed in the process of production and use, that is, poor hygroscopicity, easy to generate static electricity in the process of use, and thus bring harm to industrial production and people's lives, which makes it harmful to synthetic materials. The research on the antistatic properties of fibers has attracted more and more attention. [0003] Acrylic fiber is a widely used chemical fiber with fluffy texture, soft hand feeling, low density, good warmth retention, high resilience, excellent light resistan...

AI Technical Summary

Problems solved by technology

However, due to its hydrophobicity and insulating properties, its electrostatic phenomenon is serious

Acrylic fiber is difficult to bundle during processing, and it will be entangled with the workpiece, and the finished product is easy to pollute and vacuum; when wearing it, it will cause discomfort due to discharge

[0004] In the patent No. CN03115288.0, the vegetable protein-acrylic fiber composite fiber and its manufacture method are announced, and the acrylic fiber is modified by the vegetable protein, so that it has good antistatic properties, but in this method, the following defects still exist, 1. The high elasticity of polyurethane fibers cannot be used to improve the resilience of soybean protein and polyacrylonitrile fiber blended composite fibers; at the same time, it does not have a reasonable ratio between nano-ATO and carbon nanotubes with different shapes and properties to greatly improve The electrical conductivity of polyacrylonitrile fibers; 2. In the process of drying the fibers, the time of the heat in the drying box cannot be prolonged through the two cross-set baffles, so that the fibers are heated more evenly and the drying effect is good; and it cannot Make the fabric more compact and not loose
