Research And Performance Test Of Antistatic Coated Fabrics

Electrostatic exits in all places at all time. It made people’s life available for convenience, but the harm caused by static electricity in many aspects was more memorable. In textile industry, because of static electricity, textiles adsorbed dust and adhered to body. This brought discomfort feeling when it was worn. Electrostatic in synthetic fiber affected the normal spinning process, thus reduced product quality. And in electronic industry, due to the existence of static electricity, it badly disturbed normal work of precise electronic instrument, even worse punctured the integrated circuit and led to scrap. In petrochemical industry, combustion and explosion affected by static electricity caused a significant damage of property and members. Antistatic can be prepared protective clothing for oil and chemical industry,so improving the antistatic performance of fabrics has an extremely vital significance.In the paper, antistatic finishing agent with antistatic filler as conductive phase and resin as adhesive was used to coat polyester fabrics in order to conform to durable antistatic fabrics standard GB12014-2009. Through the analysis of antistatic and physical and mechanical properties of finished fabrics, a kind of method for preparing antistatic fabrics was exploded.First, ATO antistatic fabric was prepared by coating in the paper. The influences of ATO solution concentration, baking time and baking temperature on fabrics were studied. By orthogonal experimental method, the optimal preparation process of ATO antistatic coating fabrics was determined as follows:ATO solution concentration55%, baking time120s and baking temperature100℃. Under this condition, fabric surface resistance was3.11×1010Ω, which met B level of standard GB12014-2009.Second, also the same method was used on carbon black antistatic fabrics. The influences of coupling agent type, use method of coupling agent, the amount of coupling agent, the amount of carbon black, the amount of curing agent and curing time on fabrics were studied. Through orthogonal experiment, the optimum preparation process of carbon black coating fabrics was determined as follows:the amount of coupling agent1.3%, curing time9h, the amount of carbon black23%and the amount of curing agent6%. According to the parameters above, fabric surface resistance was2.96×105Q, which met A level of standard GB12014-2009.In order to analyze the influence of coating finish on fabrics physical and mechanical properties, thickness, gas permeability, moisture penetrability and breaking strength were tested. Compared to raw fabrics, there was a little change in thickness, gas permeability, moisture penetrability and breaking strength in ATO antistatic coating fabrics. For carbon black antistatic coating fabrics, there was also a little change in thickness, gas permeability and moisture penetrability, but a significant change in breaking strength.
