According to the JIS L 1094 standard, when the environment condition is 20 DEG C*40%RH, the voltage of the friction belt of the fabric is less than 3000V; according to the JIS L 1092 standard, the water-repellency level of the fabric is more than 4-5 level, the moisture rate error of the water-repellency anti-static fabric is more than 2.5%; and the fabric disclosed by the invention is good in water-repellency static resistance and durability.
Description
Technical field
The present invention relates to a kind of water anti-static fabric and production method thereof of refusing.
Background technology
Nowadays the effect of clothes is not warming resisting cold, the raising of Along with people's demand, and the textiles of various functions arises at the historic moment, and is antibiotic as antistatic, fire-retardant, refuses water, preserves moisture multiple function textile such as fragrance.Wherein having the clothes of refusing water anti-static function field such as move out of doors receives an acclaim.
In general, hygroscopicity and antistatic behaviour are to be mutually related, and hygroscopicity and WATER REPELLENCY are again opposed.And want that anlistatig to have water repellency simultaneously just difficult in moisture absorption, moreover has WATER REPELLENCY simultaneously and antistatic behaviour wants again to guarantee that the durability of these two kinds of performances is just more difficult.
Have at present and use water repellent and antistatic agent treatment fabric simultaneously,, require or the not good problem of durability but still exist wherein a kind of performance not reach though such method for sorting makes fabric have WATER REPELLENCY and antistatic behaviour simultaneously.
Therefore in order to address the above problem,, be employed in damascene conductive fiber in the fabric at Chinese patent CN200710019576.2 and CN200910174303.4; Refuse water treatment then; Thereby reach the antistatic preferably water effect of refusing, also can keep durability, but the requirements of weaving process of conductive fiber is high; Most of conductive fibers are dark, and also there is certain problem in dyeability.
Summary of the invention
The object of the present invention is to provide a kind of antistatic property that has excellent durability simultaneously, refuse water effect and water antistatic behaviour fabric and the production method thereof of refusing with low cost.
Technical solution of the present invention is:
The water anti-static fabric of refusing of the present invention is made up of pure polyamide fabric layer and the resin bed that is coated on the surface of filament in the tissue layer, and according to JISL 1094 standards, when environmental condition was 20 ℃ * 40%RH, the frictional electrification of this fabric was pressed in below the 3000V; This moisture absorption rate variance of refusing the water anti-static fabric is more than 2.5%.
Fabric of the present invention uses pure polyamide fabric to be base cloth, and the pure polyamide fabric here comprises the woven fabric or the knitted fabric of pure polyamide fiber.
According to JIS L 1094 standards, when environmental condition was 20 ℃ * 40%RH, the frictional electrification of this fabric was pressed in below the 3000V after the home washings 10 times.
According to JIS L 1092 standards, 10 times front and back of this fabric home washings are refused the water degree and are 4～5 grades.
The resin bed on filament surface is for refusing the water-resin layer in the pure polyamide fabric layer of the present invention, and refusing the water-resin layer is to form by refusing water-resin and bridging agent reaction back.
At first be to select pure polyamide fabric for use; Use formic acid or phenmethylol treatment fluid (concentration is 10～150 grams per liters) to handle, treatment temperature is 40～100 degree, and the processing time is 5～30 minutes; Clean; Carry out ordinary stain then, obtain pure polyamide fabric, the moisture absorption rate variance of this pure polyamide fabric is more than 2.5%; Use the dressing liquid of refusing water-resin and bridging agent composition to carry out water repellent finish then, obtain refusing the water anti-static fabric.
Above-mentioned formic acid or phenmethylol treatment fluid, preferred phenmethylol treatment fluid, treatment fluid concentration is 10～150 grams per liters, preferred 50 grams per liters～120 grams per liters.
Above-mentioned water-repellent finishing method is following:
At first preparation contains the dressing liquid of refusing water-resin and bridging agent, and dressing liquid component used herein and weight portion are following:
Wherein, refusing water-resin is that fluorochemical is refused water-resin, polyurethane dendrimer and refused water-resin or aliphatic paraffin and refuse in the water-resin one or more; Bridging agent is one or more in melamine class, isocyanates, the imines class; Catalyst is the organic amine salt series catalysts.
Pure polyamide fabric layer immerses in the above-mentioned dressing liquid that makes, and two soak two rolls, and liquid carrying rate is 30～90%; Polyamide fabric after will padding carries out drying, typing, and baking temperature is 100～150 ℃, and be 1～4min drying time, and setting temperature is 160～180 ℃, and shaping time is 0.5～3min.
The invention has the advantages that processing method is simple, cost is low, this fabric has antistatic behaviour when having WATER REPELLENCY, and refuses the water antistatic behaviour and have better washing resistance.
