Should the seat belt use high-strength polyester webbing or high-strength nylon webbing?
High-strength webbing is divided into high-strength nylon webbing and high-strength polyester webbing according to the material. For customized high-altitude work safety belts, I have been hesitant to choose polyester material or nylon material. If you also have this doubt, you may wish to read below.
Price factor:
Polyester yarn is cheaper than nylon yarn. Customers who are concerned about price factors will choose polyester.
Performance factor:
1. Polyester fabric is not easy to wrinkle, and is quite wide, with good dimensional stability and good shape retention. Polyester is resistant to sunlight, acid but not alkali
2. Nylon has high strength, good elastic recovery ability, excellent wear resistance, and better hygroscopicity and dyeing than polyester. However, the light resistance is not good, and the fiber strength will decrease after long-term exposure to sunlight, and the color will turn yellow.
