"Class A anti-static fabrics and garments" passed the provincial appraisal

The “Grade A anti-static fabrics and apparel” researched and developed by Baoding Sanyuan Textile Technology Co., Ltd. in Hebei Province recently passed the new product appraisal organized by the Hebei Science and Technology Achievement Transformation Service Center and the Baoding Science and Technology Bureau.

Class A anti-static fabrics and apparel items are new products developed in accordance with the requirements of GB12014-2009 "anti-static clothing" standard A-class products, its anti-static properties greatly improved, can reduce production failure, reduce the fire caused by electrostatic shock , Explosion accidents and injuries to the human body are widely used in high flammable, explosive, high-risk, and highly sensitive areas such as aerospace, military, and integrated circuits. Many current fires are caused by static electricity.

By increasing the cross-section of the electrostatic wire (increasing the diameter of the electrostatic wire) and optimizing the quality and content of the carbon powder, the project reduced the particle size of the carbon powder to meet the requirements of the A-rated resistance of less than 107Ω/30cm as specified in the “Antistatic Clothing” standard. In the spinning process, Sanyuan Textile broke through the traditional line-jointing process. By adjusting the twist of different yarns, the winding structure of the yarn was changed, and the surface resistivity of anti-static fabrics and garments was greatly reduced to meet the requirements of the new standard. . The structure of the electrostatic filament used in the product was changed to “embedded” as “back-embedded”, and the way and spacing of the yarn arrangement were calculated and designed to improve the antistatic performance. The charge density was less than 0.2μC/piece. According to the company's introduction, this product has been used by users well and is now in mass production.
