development trend analysis of antistatic fabric at home and abroad

With the development of technology and the enhancement of people’s safety awareness, people have higher and higher requirements for safety protective clothing. Anti static fabric not only meets the anti-static function, but also differs from ordinary anti-static fabric mainly in the concept of “super clean”. Relative humidity is less than 30%, and the charge of pure cotton clothing is the same as that of chemical fiber clothing, Anti static clothing made of subconductor materials should be worn in high voltage live working places. According to different needs, the needs of anti-static are also different. The selection of anti-static super clean fabric can only be made by the application units according to the requirements of the working environment or after testing or based on experience. This paper makes a simple analysis on the development status and trend of antistatic fabric at home and abroad

since the 1960s, people have been exploring the development of conductive fiber to eliminate the static electricity of fiber and its fabric. The earliest conductive fiber is stainless steel fiber developed in the United States, but it is difficult to blend with ordinary fiber, and the product use effect is not good; 1n 1974, DuPont successfully developed a kind of concentric round skin core composite conductive fiber. 1n textile processing, as long as 1% – 2% is mixed, satisfactory results can be obtained; 1n 1978, Toray’s island type conductive acrylic fiber not only has good conductive effect, but also has excellent physical properties. To prevent the accumulation of static electricity in clothing, conductive fibers are mixed into the fabric approximately at intervals or evenly during weaving. 1n the sixties and seventies of the last century, the United States, Japan and other countries developed the test method of textile fabric static electricity

due to the lag of development and production of conductive fiber in China, up to the end of last century, few of our national defense electrostatic fabrics used imported conductive fiber to produce Antistatic Fabrics, most of them were anti-static chemical finishing for ordinary fabrics, or replacing Antistatic Fabrics with pure cotton fabrics with good moisture absorption. There is no test standard for anti-static fabrics. The test of anti-static clothing refers to the anti-static safety guide of Japan. 1t was not until the end of 1980s that the test standard of anti-static clothing, GB12014-89, was formulated< From the end of last century to the beginning of this century, China has successively developed stainless steel metal fiber, nylon based and polyester based carbon containing conductive fiber, nylon based and polyester based oxide containing conductive fiber, which has greatly promoted the production of our national defense electrostatic fabric, and cultivated many professional development talents Production of antistatic fabric enterprises. Especially referring to the anti-static fabric standards of Europe, America and Japan, the anti-static fabric and clothing standards of gb12014-2009 have made the performance of China's anti-static fabric meet or even exceed the performance requirements of Europe, America and Japan people have higher and higher requirements for anti-static clothing, which is comfortable and multifunctional. 1n order to prevent the accumulation of static electricity in clothing, anti-static fabric is used for sewing work clothes. For example, anti-static fabric is required to have moisture absorption and perspiration function in summer, anti-static and fireproof fabric is required in flammable and explosive places such as petroleum and chemical industry, and anti-static and anti tearing fabric is required in electric field operation. 1n short, anti-static fabric is developing in the direction of combining with other functional fabrics to form anti-static multi-functional fabric
