Abstract
The invention relates to a warp-knitted aramid mesh fabric used for high-temperature-resistant hose reinforcing materials of automobiles, which consists of a plurality of fabric tissue units. Each fabric tissue unit comprises six transverse loop rows and two longitudinal loop rows, two adjacent fabric tissue units are connected through the third transverse loop row and the longitudinal loop row adjacent to the sixth transverse loop row by yarns, the third transverse row, the fourth transverse row, the fifth transverse row and the six transverse loop row surround to form meshes between the first longitudinal loop row and the second longitudinal loop row of each fabric tissue unit, and the first transverse loop row, the second transverse loop row and the third transverse loop row surround to form meshes between the second longitudinal loop row of each fabric tissue unit and the first longitudinal loop row of the adjacent fabric tissue unit. The warp-knitted aramid mesh fabric is processed by high-strength uniform-evenness aramid yarns spun by a compact spinning device, and the advantages of the aramid yarns of high strength and fine high-temperature resistance are developed.
Description
technical field [0001] The invention relates to a warp-knitted aramid fiber mesh fabric used as a reinforcing material for high-temperature-resistant hoses of automobiles, and belongs to the technical field of textiles. Background technique [0002] Rubber elbow is an indispensable non-metal fitting on the car, mainly used to transport coolant, hot air and oil medium. The general requirements for automotive hoses are: smooth appearance, natural assembly, good bending performance, high bearing pressure, small compression deformation, and superior pulse performance. The rubber hose with knitted (warp-knitted or weft-knitted) fabric as a reinforcing material not only improves the burst strength and toughness of ordinary rubber hoses, but also makes the ports easy to expand in diameter and has good resilience, which is conducive to the assembly of rubber hoses. A certain bending radius is allowed. Since the knitted fabric is relatively sparse, the inner layer glue and the oute...
