Why is there static electricity in the production process of non-woven fabrics

Nonwovens provide specific functions such as absorption, liquid wet wipes material exclusion, elasticity, extensibility, softness, strength, flame retardancy, redundancy, washability, buffering, filtration, bacterial barrier and sterility. In combination with other materials, they provide products with different characteristics of spectrum and used alone or as clothing components, furniture, health care, engineering, industry and consumer goods.

It is because of its wide application, many people will have a question: why is static electricity generated during the production of non-woven fabrics? The problem of electrostatic generation during the production of non-woven fabrics is mainly caused by the low moisture content in the air when the fiber and card clothing contact, which can be divided into the following points:

（1） The weather is too dry and the humidity is not enough.

（2） When there is no oil on the fiber, there is no antistatic agent on the fiber. Because the moisture regain of polyester cotton is 0.3%, the lack of antistatic agent results in static electricity during production.

（3） If the oil content of fiber is low and the content of electrostatic agent is low, static electricity will be generated.

（4） Due to the special molecular structure of silicone polyester cotton, there is almost no moisture on the finish, so it is relatively easy to generate static electricity during production. Generally, the sliding degree of handle is positively proportional to the static electricity, and the smoother the silicon cotton, the greater the static electricity.

（5） In addition to humidifying the workshop, it is also an important work to eliminate the oil-free cotton effectively in the feeding stage.
