The biggest problem with slings is that it is difficult to ensure their own metal properties in harsh environments. The most common problem is that metal slings will corrode and rust when used in harsh environments for a long time, and water and humid air are the main reasons for this problem. However, there is one kind of slings that does not need to worry about the occurrence of this problem. It is a colored lifting belt.
The reason why the colored sling will not rust is that it is made of non-metallic material and will not be affected with damp and mildew. It also has an important relationship with its unique material. The color sling is made of polyester fiber, which is commonly known as polyester.
The biggest feature of polyester is that it can hardly absorb water, which is inseparable from its special structural properties. Polyester is also a very safe fiber, which can hardly decompose and release toxic substances. In addition, the reason why polyester is used as the main raw material of color sling is inseparable from its several important characteristics.
1. It has high strength and elastic recovery capacity. Therefore, it is firm and durable, wrinkle resistant and iron free.
2. The light resistance of polyester fiber is better than that of acrylic fiber, and its light resistance is better than that of natural fiber fabric. Especially, the sun resistance behind the glass is very good, almost equal to that of acrylic fiber.
3. Polyester has good resistance to various chemicals. Acids and alkalis do not damage them to a great extent, and they are not afraid of mold and moth damage. Polyester fabric is a kind of chemical fiber clothing fabric used in daily life.
4. It is easy to wash and fast dry. The moisture absorption of polyester is very poor. The official moisture regain is 0.4%, and it hardly absorbs water. Pure polyester clothes are washable and wearable. After washing, they can be worn as long as they are dewatered. This performance makes it widely used in outdoor products.
This is the unique advantage of polyester, and also the important reason why it is widely used in color belt lifting belts.
