High-strength fiber double-layer interweaved composite hose and production method thereof

Abstract

The invention discloses a high-strength fiber double-layer interweaved composite hose and a production method of the composite hose. The high-strength fiber double-layer interweaved composite hose comprises a hose blank, wherein in an inner surface and an outer surface of the hose blank, a rubber material layer is composited on at least the inner surface of the hose blank; the hose blank is a double-layer fabric with a double-layer section, and six paths of warps form a circulative weaving tissue; the double-layer fabric comprises an inner layer and an outer layer, the outer layer comprises an outer-layer warp and an outer-layer weft, the inner layer comprises an inner-layer warp and an inner-layer weft, and the inner-layer weft is interweaved with the inner-layer warp and is also interweaved with the outer-layer warp, so that the inner layer and the outer layer are interweaved into a whole body. According to the high-strength fiber double-layer interweaved composite hose disclosed by the invention, the woven hose blank has good flexibility, high pressure resistance, a few interweaving points, small yarn strength loss and small torsion degree; superlarge-aperture and high-pressure-resistance hoses meeting the market demand can be produced without special modification on the original device; the production process is simple; the practical value is high, and the production generalization performance is excellent.

Description

technical field [0001] The invention relates to a high-strength fiber double-layer interwoven composite hose and a production method thereof. Background technique [0002] The general weaving method of hose tube blanks on the market uses warp and weft fibers to weave plain or twill hoses with single layers of warp and weft to form tubular fabrics; the fabrics are all single-layer woven, and the tube blanks produced meet the requirements of The pressure bearing capacity of the large-diameter hose cannot be lost. At present, in order to meet the high-strength hose in China, we can only choose fiber varieties, or thicken the warp and weft threads to increase the density of the warp and weft threads. However, this kind of tube blank is hard, easy to degumming, rough surface, large water flow resistance, poor wear resistance, and does not meet market demand. . [0003] For production companies, it is generally based on market demand to develop samples and organize production. ...
