Nylon is the best in the composite fibers used in the rubber industry, is of a structure braided by nylon fibers in warp and weft, and has the widest application, with outstanding advantages of excellent wear resistance, high strength and good fatigue resistance. The conveyor belt made from nylon canvas is featured by thin belt body, high strength, impact resistance, good trough formation property, large bonding force among layers, excellent flexibility and long service life, is suitable for conveying materials in medium and long distance and high transmission capacity at a high speed, and is widely applicable to such departments as mines, metallurgy, construction, ports and the like.
