State of the art

Conventional slings (synthetic fiber slings) are generally made of high strength polyester filaments, which have numerous advantages such as high strength, wear resistance, oxidation resistance, UV resistance, etc. At the same time, they are soft in texture, non-conductive and non-corrosive (without harm to the human body) and are used in various fields. Types of Sling: Many conventional sling (depending on the appearance of the sling) are divided into four categories: toroidal tapering, toroidal flat, binocular tapering, and binocular flat.

The existing sling has a complex structure. The sling resistance and wear resistance are poor, which reduces the acidic corrosion of the sling, causes the lifting items to fall, and endangers human life and health. The strength of the general sling is not high, and the sling is easy to wear out when it comes into contact with the lifting articles. The tensile strength and fatigue strength of conventional slings are poor, which leads to slight wear of the slings. Therefore, in order to solve the above-mentioned problems, an acid-resistant sling having high strength and good tensile effect is proposed.
