[0002] Yarn is a long strip of material made from fibers (such as cotton, wool, silk, chemical fibers, etc.) through spinning technology. Yarn is the basic raw material for textiles such as fabrics and knitwear, and is widely used in the production of various products such as clothing, home furnishings, and industry.

[0003] Antistatic yarn is a kind of yarn that has the function of inhibiting the accumulation of static electricity. It is usually achieved by special fiber materials or adding antistatic agents. Static electricity is an electrical phenomenon caused by the uneven distribution of charges on the surface of an object. Static electricity accumulation may cause textiles to absorb dust, damage electronic equipment, or cause fires. Therefore, antistatic yarn has been widely used in many industries.
