Abstract
A durable antistatic textile is disclosed. The textile is formed by synthetic fiber and cellulosic fiber, wherein monofilament of the synthetic fiber is covered with a nanometer leather film layer having a thickness of 10-1000 nm, and the leather film layer is obtained from azo compounds through initiation reactions. After the textile is washed for 50 times according to JISL1096F1, F2, and F3 standards, the electrification voltage by friction of the textile is below 1500 V.
Description
Technical field
The present invention relates to a kind of antistatic textile, be specifically related to a kind of antistatic textile of resistance to industrial washing.
Background technology
Anti-static precautions, from principle, is all reduce static content and lead the such mode of electrostatic to achieve the goal.For antistatic finish, one is carry out antistatic Final finishing to fabric, comprises and washes most one-bath dyeing method or Final finishing pad method.Two is by conducting fibre or the high fiber of hydroscopicity, with the fabric of blending, intertexture or the mixing of other method, or be add antistatic additive when spinning in spinning solution, to reach anti-static purpose.
Wherein, carrying out antistatic Final finishing to fabric is the surface utilizing antistatic additive to be attached to fabric, realizes anlistatig object.Generally these antistatic additive are under washing, the condition such as rub or be heated, and easily come off from the surface of fiber, thus antistatic effect can not be lasting.In order to improve above-mentioned situation, improve the adhesion effect of antistatic additive, disclose the cavitation effect that utilizes ultrasonic wave to produce in the dispersion liquid of the antistatic particle of nanoscale and other physical mechanical effects in China granted patent ZL 200510028479.0 to promote antistatic particle and be promptly embedded in the fine gap of fabric and fiber, groove and hole, then adopt adhesive to carry out shutoff process; But because the shutoff of adhesive is just in the fine gap of fabric and fiber, groove and hole, is moved between filament during washing and easily causes resin bed easily coming off after the industrial washing that washing intensity is very large, thus cause washing resistance low; Need to improve feel by adding the functional finish such as softener, along with the increase of washing times, its feel also can constantly change simultaneously.
Although and for example patent document CN101929073A, CN101492885A, CN101205651A etc. are also by nano involucra technology, improve washing resistance, but owing to using peroxidating class initator, be easy to out the problems such as the change color of ready-made article (dyeing), color spot.To dyestuff with the use of there being certain requirement, for widely application have certain restriction.
Summary of the invention
The object of the present invention is to provide a kind of antistatic textile with excellent industrial washing durability.
Technical solution of the present invention is:
A kind of durable antistatic textile, this textiles is made up of synthetic fiber and cellulose fiber blended fabric.The fiber surface forming this textiles wraps up the nano involucra layer that a layer thickness is 10 ~ 1000nm, and nano involucra layer is obtained by initiation reaction by azo compound.The Main Ingredients and Appearance of nano involucra layer is one or more in polyurethanes, aziridines, esters of acrylic acid, isocyanates or melamine compounds.According to the antistatic textile that said method obtains, after JIS L 1096 F1, F2, F3 standard wash 50 times, frictional electrification is pressed in below 1500V.
Above-mentioned nano involucra thickness is 10 ~ 1000nm, and preferably 10 ~ 500nm is as thickness < 10nm, epithelium facile hydrolysis, washing resistance is poor, and during thickness G reatT.GreaT.GT 1000nm, the feel of fabric is partially hard, lose the original flexibility of fabric and elasticity
Cellulose fibre generally adopts activity or direct dyes to dye, if meet oxidant, the easy oxidized reduction of these dyestuffs thus destroy the chromophoric group of dyestuff, such that DYED FABRICS generation look becomes, COLOR FASTNESS is deteriorated.Therefore the present invention uses non-oxidative, azo-initiator that initiation rate is high.
The Main Ingredients and Appearance of above-mentioned nano involucra is one or more in polyurethanes, aziridines, esters of acrylic acid, isocyanates or melamine compounds, preferably two or more above-claimed cpd.Consider two or more compound and, can space network be formed, not facile hydrolysis, more easily improve washing resistance.Consider the moisture pick-up properties of processing fabric feeling and epithelium, preferred acrylate class or isocyanate ester compound.
Textiles of the present invention can be woven fabric also can be knitted fabric.The kind of synthetic fiber and cellulose fibre is not particularly limited, and synthetic fiber can be one or more in terylene, nylon, acrylic fibers, polyvinyl; Cellulose fibre can be one or more in following fiber, as the cotton in native cellulose fibre or fiber crops, and the viscose glue in regenerated celulose fibre, model, sky silk or bamboo fibre.Above-mentioned synthetic fiber and cellulose fibre can purely spin also can blending.
Be deployed into working solution according to a certain percentage by film forming agent, initator and water, treat machining textile and carry out again padding processing, then carry out decatize, finally carry out hot air shaping oven dry, form nano involucra on filament surface.Film forming agent is one or more in polyurethanes, aziridines, esters of acrylic acid, isocyanates or melamine class; Initator is azo-initiator.
The present invention, by adopting azo-initiator, solves the problems such as the easy look change of textiles antistatic processing poststaining of containing cellulose fiber, having excellent antistatic properties simultaneously after initial stage of gained textiles and industrial washing.
Detailed description of the invention
Each parameter test method in the present invention is as follows.
(1) frictional electrification is at all according to JIS L 1094 standard.
(2) industrial cleaning applications (being called for short KL) is according to JIS L 1096 F1, F2, F3 standard.
