What is the cause of static electricity in non-woven fabrics?

According to different production processes, non-woven fabrics can be divided into spunlace non-woven fabrics, needle-punched non-woven fabrics, heat-bonded non-woven fabrics, pulp air-laid non-woven fabrics, wet non-woven fabrics, spunbonded non-woven fabrics, and meltblown Non-woven fabrics, etc.
Non-woven fabric, also known as non-woven fabric or non-woven fabric. Unlike common warp-knitted and weft-knitted fabrics, non-woven fabrics are composed of oriented or random fibers. Non-woven fabrics are formed by bonding fibers together by physical or chemical methods, and have the appearance and certain properties of cloth. Polypropylene (PP material) pellets are mostly used as raw materials, which are produced by a continuous one-step method of high temperature melting, spinning, laying, and hot-pressing.

With the continuous development of non-woven production technology, it has gradually become a new generation of environmentally friendly materials, which are moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable And other characteristics, are used in medical, home textiles, clothing, industry, military and other fields.

Compared with woven fabrics, the moisture regain of non-woven fabrics is generally lower, and it is easy to generate static electricity during production and use.
The spark point generated by static electricity may cause some flammable materials to explode. Sparks and static electricity will occur when wearing nylon or woolen clothes in dry weather, which is basically harmless to the human body. However, on the operating table, the electric sparks can cause anesthetic explosions and harm doctors and patients.

In order to solve this problem and make non-woven fabrics more widely used in the market, a certain proportion of antistatic masterbatch can be added in the production process of non-woven fabrics, so that non-woven fabrics can obtain excellent antistatic effects and reduce static electricity. At the same time, it will increase the price of non-woven fabrics, but for special purposes, it is necessary to increase the cost in this regard.
