Description
Technical field
The application is related to a kind of light industry textile field, and in particular to a kind of acrylic fiber and preparation method thereof.This Shen
Please it is related to a kind of fabric simultaneously.
Background technology
The manufactured goods of acrylic fiber are soft because bulkiness is good, warmth retention property is good, have good against weather and it is mould proof,
Mothproof performance, it is referred to as " artificial wool ", the warmth retention property of acrylic fibers is higher than wool by 15% or so, is widely used in clothes, decoration, production
The fields such as industry.
The warmth retention property of acrylic fiber is realized by far-infrared material under normal circumstances, i.e.,：Far-infrared textiles can be inhaled
Receive the far infrared by the change of electron energy level to the certain wavelength of human body radiation, human body after the heat of human body radiation and feel there is temperature
The effect risen, so as to have thermal effect；In addition this far infrared can human activin cell, improve blood of human body microcirculation,
Promote the metabolism of human body, improve body immunity.At present, far-infrared textiles can be by the way that ceramic powder be directly attached to
The surface of fiber, shortcoming are poor durabilities；Ceramic powder can also be added to fibrous inside in spinning process.
The antistatic behaviour of acrylic fiber is by being added to graphene by appropriate mode inside acrylic fiber, being obtained
Acrylic fiber there is antistatic, far infrared, warming, antibacterial, ultraviolet resistance.
In the prior art, to ensure the antistatic property of acrylic fiber and durability, it is necessary to add more antistatic
Agent, this kind of way can increase the spinning difficulty of acrylic fiber and acquire the mechanical strongly poor of acrylic fiber；In order to obtain
Far infrared performance, it is necessary to antistatic additive adds with ceramic powder simultaneously, the addition of ceramic powder can further increase spinning difficulty and
Deteriorate the machinery strength of fiber.Graphene is added in fiber in spinning process can obtain with antistatic, far infrared
The acrylic fiber of warming, antibacterial, UV resistance, but because graphene is dark additive, be added in fiber, fiber has
Certain color, it is unfavorable for dying light color, the graphene acrylic fiber prepared by above method, technological process is simple, but
It is to exist to have the disadvantage that：
1. color is limited to
Graphene slightly black, due to graphene fiber top layer be distributed, graphene fiber is grey, uses the fiber
Fabric can not dye light color, especially bright color, and then cause fiber color to be limited；
2. cost is too high
Graphene is distributed in whole fiber in fiber, and usage amount is high, because the price of graphene is very high, and then causes fiber
Price increase therewith；
Above-mentioned two shortcoming limits the application of graphene fiber, especially in textile garment field.
In order to expand application of the graphene in textile garment field, how by being distributed in fiber simultaneously with other additives
Inside, by the synergy of two class additives, to provide a kind of cheap, good endurance and be adapted to dye having for light color
Antistatic, far-infrared warm, antibacterial, UV resistance turn into those skilled in the art's technical issues that need to address.
