Cotton canvas structure is spun by warp and weft cotton fibers, with lower elongation, good mechanical clamping fastening and good adhesive property to rubber. It is slightly deformed at high temperature, and is suitable for places with shorter distance and less transmission capacity. The polyester cotton conveyor belt is the upgrading of the all-cotton conveyor belt, has superior physical and mechanical properties to the all-cotton conveyor belt because its tensile body is interwoven by warp polyester cotton fibers and warp cotton fibers, has excellent use performance as the belt is much thinner and lighter, and the impact resistance is greatly improved, can save energy and reduce wastes, can create favorable economic benefits for users, and is suitable for material conveyance in medium and short distance and moderate load.
