How the textile production process effectively removes the effects of static electricity
2017-08-01
 
Every winter, the appearance of static electricity will become more frequent. People are very confused about this. Why does static electricity appear in winter? This is why the winter is very dry, the electrical conductivity of the article will be reduced, so it is more prone to static electricity. Now that we know this reason, it is very simple to remove static electricity. We only need to use a humidifier to increase the humidity. And its use in the textile industry can also reduce the phenomenon of flying flowers and static electricity,
1. Relative humidity and the relationship between the wire and the friction between the mechanical surface and the fiber and the friction between the fibers, inevitably cause the fiber to be charged. When the fiber and the body have different charges, it will hinder the stretching and combing of the fiber. The interweaving and winding process proceeded smoothly. When there are different charges between the fibers, the fibers will not coincide with each other, and the hairiness will be thick, causing the light yarn to become hairy, so that the weaving breaks and the flower picking will increase, the fabric surface will be rough and form a scattered shape, and the relative humidity of the air will be improved. The specific resistance of the fiber can be lowered to increase the rate at which the charge is dissipated, thereby eliminating static electricity.
2, the relationship between relative humidity and moisture regain, the relative humidity of the air is different, the moisture regain rate of the fiber is also different. As the relative humidity of the air increases, the moisture regain of the fiber also increases, but decreases.
3, the relationship between relative humidity and strength Relative humidity has a strong influence on the fiber, can improve and improve the degree of long-chain molecules and increase the strength, in the case of cotton fiber, when the relative humidity is 60-70%, he The strength is about 50% higher than the dry state. 3. Relationship between relative humidity and elongation The fibers after moisture absorption are prone to relative displacement under the action of external force due to the increase in the distance between molecules, so the elongation of the fibers increases as the relative humidity increases. Among them, wool, silk and viscose fiber are more easily elongated than natural fibers such as cotton and hemp. As for synthetic fiber (such as polyester), the relative humidity has little effect on the elongation due to poor hygroscopicity.
4. Relationship between relative humidity and softness When the relative humidity increases, the distance between the molecules after the fiber absorbs moisture increases, so the hardness and brittleness of the fiber decrease, and the softness of the fiber is greatly improved.
