The problem of static electricity during the production of PP non-woven fabrics is mainly caused by the low moisture content in the air when the fibers are in contact with the card clothing. 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 of polyester cotton is 0.3%, the lack of antistatic agent results in the generation of static electricity during the production of PP non-woven fabrics.
3. The oil content of the fiber is low, and the relative content of the static agent will also generate static electricity.
4. Because of the special molecular structure of the oil, the silicone polyester cotton contains almost no water, and it is relatively easy to generate static electricity during production. Usually, the smoothness of the hand feel is proportional to the static electricity. The smoother the silicone cotton, PP non-woven fabrics have higher static electricity.
5. The method of preventing static electricity In addition to humidifying the production workshop, it is also an important task to effectively remove oil-free cotton in the cotton feeding stage.
Compared with PP non-woven fabric (PET) polyester nonwoven fabric, it has the following excellent properties:
1. The stability of polyester nonwoven fabric is better than that of pp non-woven fabric
Mainly in: strength, wear resistance and other properties. Because polyester nonwoven fabrics are made of special raw materials, they are made by advanced imported equipment and complex and scientific processing technology, which has far exceeded the technical content and requirements of polypropylene non-woven fabrics.
2. The heat resistance of polyester nonwoven fabrics is better than that of pp non-woven fabric
Polypropylene non-woven fabric has obvious heat shrinkage. According to the survey, when the temperature reaches 140 ℃, polypropylene non-woven fabric has obvious shrinkage, while the temperature of polyester non-woven fabric can reach about 230 ℃, compared with polypropylene non-woven fabric. Polyester non-woven fabrics have obvious characteristics.
3. The anti-aging cycle of polyester non-woven fabric is higher than that of pp non-woven fabric
Polyester non-woven fabrics are made of polyester, which is resistant to insects, abrasion, and ultraviolet rays. The above properties of polyester non-woven fabrics are higher than those of polypropylene non-woven fabrics.
4. Polyester non-woven fabric has good air permeability
Compared with PP non-woven fabrics, polyester non-woven fabrics have excellent properties such as non-absorbent, water-insoluble, and strong air permeability.
