Abstract

The invention relates to an anti-static acrylic fiber and a preparation method thereof. The fiber is prepared from, by mass, 16% of carbon nano tubes, 5% of carbon black and 79% of polyacrylonitrile in a mixed mode. The acrylic fiber is sequentially subjected to the procedures that the mixture passes a pre-drawing machine, acrylic fiber is pre-drawn, roving is carried out, spinning is carried out, dipping is conducted, drying is carried out and spooling is conducted after mixing. The acrylic fiber produced through the preparation method has high anti-static performance, low in cost, mildewproof, mothproof, easy to store and easy to restore after being washed and does not peel off after plate connection.

Description

A kind of antistatic acrylic fiber fiber and preparation method thereof

[technical field]

The present invention relates to a kind of antistatic acrylic fiber fiber and preparation method thereof, belong to textile yarn technical field.

[background technology]

Yarn fibers in existing spinning unit mainly comprises acrylic fiber and cashmere fiber, acrylic fiber gets consumer reception due to cheap times, but because labour is nervous, labour cost constantly increases, energy-consuming is too high, causes spinning cost also to strengthen gradually, simultaneously because existing acrylic fiber does not have electrically anti-, cause resistance to voltage in the process used poor, comfort level is also very poor; Existing technology processes fiber or fabric face, and at its surface sprinkling or dipping antistatic additive, but after washing, antistatic additive comes off from fiber or fabric face, affects the persistence of its anti-electric effect.

[summary of the invention]

The object of the invention is to: for defect and the deficiency of prior art, a kind of antistatic acrylic fiber fiber that good, the antistatic persistence of a kind of antistatic effect is high and preparation method thereof is provided, acrylic fiber after this kind of method makes antistatic property greatly improve, and antistatic acrylic fiber volume resistivity is generally 10 ⁹below Ω .cm.

For achieving the above object, the technical solution used in the present invention is:

A kind of antistatic acrylic fiber fiber of the present invention, described acrylic fiber comprises CNT, carbon black and polyacrylonitrile, and its mass ratio is CNT 16%, carbon black 5%, polyacrylonitrile 79%.

In the present invention: the preparation method of described antistatic acrylic fiber fiber, comprises the following steps:

(1), adopt blended or load spinning that hydrophilic surfactant active or polymer are mixed fiber inner edge;

(2), acrylic fiber carries out pre-drawing by pre-drawing machine;

(3), enter Speed frames, twist slivering by the product after drawing-off by Speed frames;

(4), enter fine spining machine, become yarn by the drawing-off of fine spining machine product;

(5), flood, after drawing-off being become spun yarn, dipping absorbs water;

(6), the spun yarn dryer after dipping is dried;

(7), by the yarn after drawing-off import automatic winder, bobbin winder checks and filters yarn;

(8), enter two-for-one twister, evenly twisted by two-for-one twister;

(9), reeled yarn, and control grammes per square metre by reeling frame.

After adopting said method, beneficial effect of the present invention is:

(1), compared with traditional acrylic fiber: soft, bulkiness is good, prevented from caking; There is antistatic property, and dyeability is better, painted comparatively bright-coloured;

(2) acrylic fiber, after this kind of method makes antistatic property greatly improve, conventional acrylic fiber volume resistivity 10 ¹⁸Ω .cm-10 ¹⁹Ω .cm, antistatic acrylic fiber volume resistivity is after treatment generally 10 ⁹below Ω .cm.

[detailed description of the invention]

Describe specific embodiment in detail the present invention below, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.

Embodiment 1

(1), by CNT 32kg, carbon black 10kg and polyacrylonitrile 158kg carry out blending by gilling machine, and adopt blended or load spinning that hydrophilic surfactant active or polymer are mixed fiber inner edge;

(2), acrylic fiber carries out pre-drawing by pre-drawing machine;

(3), enter Speed frames, twist slivering by the product after drawing-off by Speed frames;

(4), enter fine spining machine, become yarn by the drawing-off of fine spining machine product;

(5), flood, after drawing-off being become spun yarn, dipping absorbs water;

(6), the spun yarn dryer after dipping is dried;

(7), by the yarn after drawing-off import automatic winder, bobbin winder checks and filters yarn;

(8), enter two-for-one twister, evenly twisted by two-for-one twister;

(9), reeled yarn, and control grammes per square metre by reeling frame.

Select and with blended or load spinning, hydrophilic surfactant active or polymer are mixed fiber inner edge in acrylic spinning process, thus the antistatic fibre of the durability of excellent, thus make in fiber system containing spongy component, improve hygroscopicity, thus acquisition antistatic behaviour, and the fabric wash resistant be spun into, the impact do not rubbed; Select the surfactant of the good antistatic property of stability, the nonionic macromolecule with crosslinkable groups mostly, this crosslinked group participates in cross-linking and curing reaction easily, and 3 D cross-linked Stability Analysis of Structures, hydrolysis and have higher mechanical strength, then adopts the method for dipping to carry out surface treatment to fiber, post-drying winder, this technics comparing is simple, and equipment requirement is not high.

Acrylic fiber regularity is good, impurity is few, performance of loosening is good, in concrete spinning process, to raw material shredding, mixing, just goes first to relax acutely rear, few broken few broken technological principle, the spacing and reduce cylinder speed of suitable increasing cotton roller part, improve the speed of fan to a certain extent, ensure the output of Yarn homogeneous, coarse sand adopts larger twist factor, spinning process adopts larger back zone roller gauge, less nip gauge and less back zone drafting multiple, choose twist factor on the low side, will select suitable Yarn tension during winding procedure.

The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
