Description

TECHNICAL FIELD

[0002] Polyester, the chemical name is polyethylene terephthalate (PET), is a synthetic fiber with excellent comprehensive performance and extremely wide application. It has high strength, high elastic recovery rate, excellent wrinkle resistance, chemical resistance and dimensional stability. Since industrialization, it has rapidly become a basic material in the fields of textiles, clothing, industry, etc. However, as a typical hydrophobic polymer material, polyester has extremely high insulation (volume resistivity is usually 10 14 -10 16 Ω·cm). This characteristic leads to the generation and accumulation of static electricity during production and processing (such as spinning, weaving) and use due to friction, contact, separation, etc. This defect not only causes fabrics to easily absorb dust, be uncomfortable to wear, and entangle the skin, but also constitutes a serious safety hazard in specific industrial fields such as petrochemical industry, electronics manufacturing, aerospace, medical surgery, and operation of flammable and explosive products.
