Causes of static electricity during PP nonwoven production

Causes of static electricity during PP nonwoven production


The problem of static electricity during the production of PP non-woven fabrics is mainly due to the low moisture content in the air when the fibers and the clothing touch, 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) The fiber oil content is low, and the relative static agent content will also generate static electricity.


(4) Because of the special molecular structure of SILICONE polyester cotton, the oil contains almost no water, and it is relatively easy to produce static electricity during production. Generally, the slip of the feel is positively proportional to the static electricity. Big.


(5) Methods of preventing static electricity In addition to moisturizing the production room, it is also an important task to effectively eliminate oil-free cotton during the cotton feeding stage.
