Cashmere sweater static
It turned out that the cashmere sweater also generates static electricity during the wear process, but only slightly lower than the chemical fiber. Therefore, it is considered that a pure cashmere sweater should not generate static electricity. This is actually a misunderstanding. This should be based on the characteristics of textile materials. Textile material is an insulating material with high electrical resistance. The friction between fibers and fibers, fibers, and other objects during the textile processing or during wear may cause charge transfer on the surface of the object to generate static electricity. Wool fibers (such as wool, cashmere, etc.) such as cellulosic fibers (cotton, hemp, viscose, etc.) also have higher electrical resistance. The amount of charge they have when rubbing with other materials is 2-40 times higher than that of cotton and other fibers. This can cause static electricity. In addition, the static electricity generated by the change of climatic conditions is also different. Dry wool fibers have higher resistance than electric resistance, and it is difficult to eliminate electrification. The moisture regain rate is high and static electricity easily disappears. The moisture regain of chemical fibers is much lower than that of wool fibers, so chemical fiber fabrics are produced. The electrostatic phenomenon is much more serious than wool fabrics. At the same time, if the fibers are arranged neatly and in close contact, static electricity within the fiber is relatively easy to conduct and disappear in the contact area; conversely, if the fiber arrangement is loose and the contact area is small, the charged charge of the fiber is not easily transmitted, and the static electricity Not easy to disappear. It can be seen that the generation of static electricity is related to factors such as moisture regain, air humidity, raw material properties, and fiber structure. It is not surprising that the static electricity generated by the friction between the clothes under the dry conditions of the cashmere sweater is particularly serious, especially when it is worn together with the purified fiber clothes to generate static electricity. After being charged with static electricity, clothes are prone to attract dust and are easily contaminated, but they have no effect on human health.
UHMWPE fabric, also known as ultra-high molecular weight polyethylene fabric, is a type of synthetic fabric made from ultra-high molecular weight polyethylene fibers. This type of fabric is known for its exceptional strength, durability, and abrasion resistance, making it ideal for a variety of applications.
