Gum dipping canvas for horizontally strengthening toughness and production process thereof

Abstract

The invention discloses gum dipping canvas for horizontally strengthening toughness and a production process thereof. Fabrics adopted in the gum dipping canvas for horizontally strengthening toughness comprise low-shrinkage type polyester industry silks with 550dtex of warps, which are twisted into 100-120 twists / m, or 420-840D chinlon 66 industry silk which are twisted into 100-120 twists / m, with warp density of 150-250 pieces / 10 cm; and HMLS (High-Modulus Low-Shrinkage) industry silks with 3300dtex of wefts after plying, which are twisted into 70-120 twists / m, with weft density being 70-120pieces / 10 cm. The fabric is of weft rib structure. The gum dipping canvas for horizontally strengthening toughness has the performance indexes as follows: warp direction strength of more than 30 N / mm, weft direction strength of more than 200 N / mm, warp direction elongation at break of more than 25%, weft direction elongation at break of less than 25%, warp crimpness of less than 1%, and weft crimpness of less than 1%. According to the gum dipping canvas for horizontally strengthening toughness, the weft crimpness is greatly reduced and the toughness of the gum dipping canvas is enhanced.

Description

technical field [0001] The invention relates to a dipped canvas for rubber products and a production process thereof, belonging to the technical field of industrial fabrics. Background technique [0002] Mechanical rubber products: tubular conveyor belts, elevator handrails, etc., are long-distance belt-shaped rubber products that form a certain curved surface in the horizontal direction, and the longitudinal mechanical strength of the rubber products and the geometric shape of the horizontal curved surface must be maintained , the skeleton material must be used: dipped canvas. [0003] At present, my country's elevator handrails are widely used, and have been widely used in various indoor and outdoor buildings such as shopping malls, subways, theaters, etc. With the further acceleration of my country's national economy, the improvement of living standards. Its application will be more extensive. [0004] Tubular conveyor belt is a new type of conveyor belt. During the tra...
