经纬线正反捻输送带用交织浸胶芯布

Abstract

本发明属于纺织技术领域,特指一种经纬线正反捻输送带用交织浸胶芯布,由经线及纬线交织编织而成的白坯布,所述的经线、纬线为由两股以上的原料丝加捻形成的正捻纱和由两股以上的原料丝加捻形成的反捻纱,经线两根为一组,每组的两根经线经向形成有间隔排列的正扭结点及反扭结点,纬线紧密设置在相应的正扭结点、反扭结点或反扭结点、正扭结点与两根经线形成的闭环内,白坯布的外表现设置有一层以上浸胶形成的胶层,原料丝为锦纶长丝或涤纶长丝,本发明通过经线交织编织将纬线固定,编织形成的芯布不易变形,使用寿命长;制作形成的输送带,远距离输送不跑偏;胶层与橡胶粘合,不跑偏,延长输送带使用寿命。
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.
