Why does static electricity occur during the production of non-woven fabrics? The problem of static electricity during the production of non-woven fabrics is mainly caused by the low moisture content in the air when the fiber and the card clothing are in contact. It 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 rate of polyester cotton is 0.3%, the lack of antistatic agent results in static electricity during production.
(3) The fiber oil content is low, and the relatively low content of electrostatic agent will also generate static electricity.
(4) SILICONE polyester cotton because of the special molecular structure of the oil agent, there is almost no moisture on the oil agent, and it is relatively easy to generate static electricity during production. Usually, the smoothness of the hand feel and the static electricity are in a positive ratio. The smoother the SILICONE cotton, the more static Big.
(5) In addition to humidification in the production workshop, the method to prevent static electricity can effectively eliminate oil-free cotton during the feeding stage is also an important task.
