Is it easy to generate static electricity when wearing clothes made of polyester yarn?

Clothing made of polyester yarn fabric is indeed prone to static electricity. This is due to the chemical properties of polyester (polyester fiber) itself - its moisture absorption is extremely low (with a moisture regain of only about 0.4%), and it hardly absorbs moisture from the air, which is a key factor in helping the fiber conduct electricity and dissipate static electricity. In dry environments (such as indoor heating in winter), when polyester fibers rub against other materials or skin, electrons tend to accumulate on the surface and are difficult to conduct away, resulting in significant static electricity. In addition, the smooth surface and tight structure of polyester fibers further hinder the dissipation of charges. Although some polyester fabrics may improve this problem by adding conductive fibers or anti-static coatings, conventional polyester yarn products without special treatment are still prone to static electricity, which may cause clothing to adsorb onto the body, generate electric sparks, or absorb dust.
