Embodiment Construction

[0016] The present invention will be further described below with specific embodiment, see figure 1 —3:

[0017] The warp and weft thread positive and negative twist conveyor belt is interwoven with dipped core cloth, and the white fabric 6 is interwoven and woven by warp 1 and weft 2. The warp 1 is a positive twist yarn formed by twisting more than two strands of raw material silk and The anti-twisted yarn formed by twisting two or more raw material yarns, the weft 2 is a normal twisted yarn formed by twisting two or more raw material yarns and an anti-twisted yarn formed by twisting two or more raw material yarns , the warp 1 and the weft 2 are arranged according to the interval of positive twist and reverse twist or are arranged according to the interval of reverse twist and normal twist. Twist 360°, anti-twist 360° to form positive kink points 3 and anti-kink points 4 arranged at intervals, and the wefts 2 are closely arranged on the positive kink points 3, anti-kink poin...

Abstract

The invention belongs to the technical field of textiles and particularly relates to warp and weft forwards and backwards entwisted interwoven impregnated core fabric for a conveyor belt. The white body fabric is formed by interweaving warp and weft. The weft and the warp are respectively composed of forwards entwisted yarn formed by twisting at least two strands of raw material yarn and backwards entwisted yarn formed by twisting at least two strands of the raw material yarn. The two strands of the warp form a group and the two strands of the warp of each group are used for forming forwards entwisted knots and backwards entwisted knots in the warp direction, wherein the forwards entwisted knots and the backwards entwisted knots are arranged at intervals. The weft is compactly arranged at the corresponding forwards entwisted knots and the corresponding backwards entwisted knots or in closed loops which are formed by the backwards entwisted knots, the forwards entwisted knots and the two strands of the warp. The outer surface of the white body fabric is provided with at least one glue layer which is formed through impregnation. The raw material yarn is chinlon filament yarn or polyester filament yarn. The warp is interwoven to fix the weft, the woven core fabric is not prone to deformation, the service life is long, off tracking is avoided in long-distance conveying with the manufactured conveyor belt, the glue layer and the rubber are stuck and off tracking is avoided. The service life of the conveyor belt is prolonged.

Description

Technical field: [0001] The invention belongs to the technical field of textiles, in particular to an interwoven rubber-impregnated core cloth for forward and reverse twist conveyor belts of warp and latitude threads. Background technique: [0002] Conveyor belt is a composite body, generally composed of three parts: skeleton material, covering layer and bonding layer material, and bottoming material. decisive factor. In the process of long-distance conveying, the conveyor belt is prone to deviation problems, resulting in the failure of the normal operation of the conveyor belt and the phenomenon of broken chains, which will affect the project. Conveyor belt core cloth plays a very critical role as the skeleton material of the conveyor belt. Invention content: [0003] The object of the present invention is to provide an interwoven dipped core cloth for forward and reverse twisted conveyor belts with a long service life and a conveyor belt that is not easy to deviate whe...
