Problems solved by technology

At the same time, because the elasticity of polyester fiber and nylon fiber is still limited, under the effect of larger roller tension, the tension is the largest when entering the front end of the tensioning wheel, and the tension is the smallest when leaving the rear end of the tensioning wheel. Finally, it is very easy to cause uneven force on the conveyor belt, so the conveyor belt will deviate to the left or right, that is, the phenomenon of snaking
In addition, after the conveyor belt is under tension, due to the poor elastic recovery of polyester, the length of the conveyor belt will be stretched and cannot be recovered. Therefore, the distance between the tensioning pulleys must be continuously increased during use, or the conveyor belt must be reduced. The length size, which will undoubtedly cause unnecessary waste of time and cost

Abstract

The invention relates to a high-elastic industrial fabric for conveyor belts and a preparation method thereof. The industrial fabric is a three-dimensional textile industrial fabric woven from mixed warp yarns and weft yarns with high elasticity. The mixed warp yarns are composed of a thermoplastic elastic The thermoplastic elastomer monofilament and at least one high-strength industrial filament are spun side by side at intervals; during preparation, a thermoplastic elastomer monofilament and at least one high-strength industrial filament are spaced side by side, and are arranged repeatedly, and then the warp yarn and the corresponding The weft yarn can be woven into a three-dimensional textile industrial cloth by a textile machine. Compared with the prior art, the industrial fabric prepared by the present invention can prevent the conveyor belt from snaking, and can effectively avoid the elongation of the conveyor belt, has excellent elastic recovery, is economical and practical, and has high tensile strength. The field of conveyor belt has a very good application prospect.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt manufacture, and relates to a high-elastic industrial cloth for conveyor belts and a preparation method thereof. Background technique [0002] In the field of conveyor belt manufacturing, lightweight conveyor belts are mainly composed of fiber fabric cores and elastomer coatings. Conveyor belts have certain cladding adhesion firmness and necessary tensile strength, bendability and lateral stability, etc., but under special working conditions, conveyor belts are also required to have considerable extensibility and tensile recovery sex etc. [0003] At present, the existing industrial fabrics for conveyor belts on the market mostly use polyester monofilament in the weft direction, polyester long fiber and polyester staple fiber in the warp direction, and use PVC, TPU, PE, etc. as covering coatings. The subsequent properties such as extensibility and stretch recovery are greatly restricted. ...
