Principle of anti-static fabric

1. The generation of static electricity: The static electricity on the human body is mainly caused by the friction between clothes or between clothes and the human body. Because the atomic structure of different materials is different, the "charged amount" is different when wearing clothes of different materials, such as wearing clothes made of chemical fibers. It is easy to generate static electricity, while cotton clothes produce less static electricity. Moreover, a dry environment is more conducive to the transfer and accumulation of electric charges, so in winter people will feel that the static electricity on the body is relatively large, and it is easier to generate static electricity, so increasing the humidity of the environment can effectively reduce static electricity. When the human body is moving, the friction between the skin and clothes and between clothes and clothes will generate static electricity. As household appliances increase and people wear more chemical fiber clothes in winter, the static charge generated by household appliances will be absorbed by the human body and accumulated. In addition, the walls and floors in the house are mostly insulators and the air is dry, so they are more susceptible to static electricity. 2. The harm of static electricity: When the electrostatic charge on the surface of an object accumulates to a certain extent, electrostatic sparks will appear when two objects with different charges are separated or in contact, which is the phenomenon of electrostatic discharge. The main causes of static electricity are friction, piezoelectric effect, induction electrification, and adsorption electrification. In industrial and agricultural production, static electricity has a great effect, such as electrostatic flocking, electrostatic spray paint, electrostatic insect removal, etc. However, due to the existence of static electricity, some dangers and accidents may also occur, such as fire and explosion accidents caused by static discharge, which often cause huge personal and property losses. Static electricity is also dangerous to the human body. According to medical experts, static electricity can bring certain harm to the human body. The electrostatic interference generated by the human body can change the normal potential difference of the human body surface, affecting the normal electrophysiological process of the myocardium and the normal conduction of the electrocardiogram without interference. This kind of static electricity can aggravate the patient’s condition or induce premature beats, etc. The long-lasting static electricity can also increase the alkalinity of the blood, resulting in a decrease in the calcium content in the serum and an increase in calcium excretion, which can cause skin itching, pigmentation, and affect human health. The body's physiological balance interferes with human emotions. Many computer workers have facial diseases such as erythema and hyperpigmentation on the face. The static electricity generated by the computer screen attracts a large amount of suspended dust, which causes facial irritation. In addition, because the skin of the elderly is relatively drier than the young, coupled with factors such as the aging of the cardiovascular system and the weakened anti-interference ability, they are more susceptible to static electricity and cause cardiovascular diseases. 3. The processing methods of anti-static fabrics usually include: The mechanism of the first two methods is to increase the moisture regain of the fabric, reduce the insulation, and accelerate the leakage of static electricity. Therefore, if the processing effect is not durable or significant in a dry environment or after multiple washings, it is usually applied to ordinary clothing fabrics. Only the third method can permanently and efficiently solve the static electricity problem of textiles, so it is widely used in the production of anti-static work clothes. Stainless steel fiber, sub-conducting fiber, anti-static synthetic fiber and polyester-cotton blended or blended into an anti-static cloth, this anti-static fabric can automatically corona discharge or leakage discharge, can eliminate clothes and human body charge, prevent clothing The accumulation of static electricity effectively eliminates the conditions that cause static discharge. Anti-static clothing, anti-static hats, anti-static socks, anti-static shoes made of anti-static fabrics are widely used in industrial and agricultural production and daily life.
