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 fibers contact the card clothing, 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 polyester cotton has a moisture regain of 0.3%, the absence of antistatic agents results in static electricity during production.
(3) The fiber oil content is relatively low, and the relative content of static electricity agent will also generate static electricity.
(IV) SILICONE polyester cotton has a special molecular structure, and the oil contains almost no water. It is relatively easy to generate static electricity during production. Generally, the smoothness of the feel is proportional to static electricity. Big
(5) In addition to humidifying the production room, it is also an important task to effectively eliminate oil-free cotton during the feeding stage.
