Development status of anti-static fabrics

Development status of anti-static fabrics As our country has not yet established the corresponding standards for the detection of ultra-clean fabrics or clean clothes, the selection of anti-static and ultra-clean fabrics can only be selected by each application unit according to the requirements of the operating environment or through testing or experience. The following is a brief analysis of the development status and development trend of antistatic fabrics at home and abroad.

Since the 1960s, people have continuously explored the development of conductive fibers to eliminate the static electricity of fibers and fabrics. The earliest conductive fibers developed in the United States were stainless steel fibers, but such fibers were difficult to blend with ordinary fibers and the use of products was not effective. DuPont successfully developed a kind of concentric core-shell type composite conductive fiber in the United States. In the textile processing, only 1%-2% can achieve satisfactory results; In 1978, Toray's island-type conductive acrylic fiber not only has good conductive effect. , And the fiber physical properties are excellent. To prevent static electricity from accumulating in the clothes, the fabric of the conductive fibers is roughly spaced or evenly mixed during spinning. In the 1960s and 1970s, the United States, Japan, and other countries developed a test method for static electricity in textile fabrics.

Due to the lag in the development and production of conductive fibers in China, until the end of the last century, China's anti-static fabrics, a small part of the use of imported conductive fiber production of anti-static fabrics, most of the anti-static chemical finishing of ordinary fabrics, or to better hygroscopicity The cotton fabric replaces anti-static fabrics. There is no test standard for anti-static fabrics. The anti-static clothing test refers to Japan's anti-static safety guidelines. By the end of the eighties, the testing standard for anti-static clothing GB12014-89 was established.

In the 1980s, China started research on conductive fibers. From the end of the last century to the beginning of this century, China has developed stainless steel metal fibers, nylon-based, polyester-based conductive carbon-containing fibers, and nylon-based, polyester-based conductive fibers containing oxides. Greatly promoted the production of anti-static fabrics in China, and cultivated many professional companies to develop and produce anti-static fabrics. In particular, with reference to the anti-static fabric standards of Europe, the United States, and Japan, the GB12014-2009 anti-static fabric and clothing standards have been formulated to achieve the performance of anti-static fabrics in China, even exceeding the performance requirements of anti-static fabrics in Europe, America and Japan.

With the development of technology, people's safety awareness has been strengthened, and the requirements for safety protective clothing have become higher and higher. Anti-static fabrics not only meet the anti-static function, but also the difference between anti-static ultra-clean fabrics and ordinary anti-static fabrics lies in the “cleanliness”. The concept of "relative humidity" is ≤ 30%, and the charge of pure cotton clothing is the same as that of chemical fiber clothing in the relative situation. The antistatic clothing produced by the subconductor material should be worn in high-voltage electrification sites. It is also required to be comfortable and versatile. In order to prevent static electricity from accumulating in the clothes, uniforms made of antistatic fabrics are used for the fabrics. For example, in the summer, anti-static fabrics are required to have moisture absorption and perspiration function, petroleum, chemical and other flammable and explosive sites require anti-static and fireproof fabrics, and electric field operations require anti-static and tear-proof fabrics. In short, anti-static fabrics are being applied to other industries. Functional fabric combination, the formation of anti-static multi-functional fabric direction.

Derived from the relentless pursuit of quality, and relentless focus on the details, social friends from all walks of life in the long process of development, trust and support. Integrity and pragmatic business style is more appreciated by businessmen around the country, and establish a good reputation in the industry.
