Synthetic fiber belongs to a large category of lifting belt raw materials, synthetic fiber is a general name, and divided into polyester, polypropylene, nylon and other small categories, so the types of lifting belt is divided into many kinds, so in the face of different kinds of lifting belt what should we choose?
Let's take three of the most common synthetic fibers, polyester, polypropylene and polyamide. Although the three materials are synthetic fibers, there are still some differences in their properties, and the purchase of lifting belts should be based on different operating environments. First of all, let's take a look at polyester. Polyester has high strength, and the strength of staple fiber is 2. Good elasticity, elasticity close to wool, when elongation 5% ~ 6%, almost full recovery. The heat-resistant polyester is made by melt spinning, and the formed fiber can be melted by heating again. It belongs to thermoplastic fiber. Good thermoplastic, poor fusible resistance. Then is polypropylene, the shape of polypropylene longitudinal plane flat smooth, circular section, strong elongation, polypropylene high strength, elongation, high initial modulus, excellent elasticity. Pp dyeing is poor, chromatography is not complete, but you can use the method of liquid coloring to make up for the deficiency, and then pp has a good acid and alkali resistance. Finally, nylon, nylon wear resistance is excellent, this is a lot of materials can not be comparable, nylon elasticity and elastic recovery is excellent. And has a good moisture absorption.
These are the characteristics of the three most common lifting belt materials, each material has certain advantages, and we can choose according to the different operating environment.
