Problems solved by technology

[0002] Since the operating temperature of the existing ultra-high molecular weight polyethylene (UHMWPE) fiber ropes generally cannot exceed 100 degrees, the existing UHMWPE fiber twisted ropes are obtained by the following methods in order to improve the wear resistance and high temperature resistance: the surface of the rope is used during manufacture. Metal material cladding, the defect of this method is that when it is used for a long time under high temperature conditions, the metal will transfer heat to the inner rope and cannot achieve the effect of wear resistance and high temperature resistance; and the cladding material has great rigidity feature, it can only be used in places with large bending radii, which limits the projects that require soft use

Embodiment Construction

[0007] The present invention (see accompanying drawing) adopts polytetrafluoroethylene and single linear density 1dtex-10dtex fiber, multifilament linear density 200dtex-6000dtex ultra-high molecular weight polyethylene fiber; Merge or twist on the machine to form a rope yarn with a linear density of 200dtex-50000dtex; then use a rope yarn with a linear density of 200dtex-50000dtex to merge or twist into a rope strand 1 on the rope stranding machine (see attached picture); use the rope strands to weave in eight or twelve strands Twisted or braided rope machine, braided into a diameter of 1mm-102mm, linear density (meter weight) 0.5Ktex-7500Ktex (g / m) eight or twelve strands braided twisted or braided rope; twist coefficient (lay length) is the diameter of the rope 3.5-10 times; and then use a plastic extruder to coat the rope surface with a thickness of 1mm-2mm and low melting point (below 100°C) polyethylene, and then coat it with PTFE 2 with a thickness of 1mm-5mm (see attach...

Abstract

The invention discloses an ultrahigh molecular weight polyethylene abrasion and temperature resistant composite braided rope, relates to a textile rope, and provides an abrasion and high temperature resistant braided rope. Fibers with single density of 1 to 10dtex and ultrahigh molecular weight polyethylene fibers with composite fiber density of 200 to 6,000dtex are merged or twisted into rope yarns with density of 200 to 50,000dtex; the fiber rope yarns with density of 200 to 50,000dtex are merged or twisted into rope strands; the rope strands are braided into an eight-strand or twelve-strand twisted rope or braided rope with a diameter of 1 to 102 millimeters and a linear density of 0.5 to 7,500Ktex; and the twisting coefficient is 3.5 to 10 times diameter of the rope. The composite braided rope is characterized in that: a layer of polytetrafluoroethylene is coated on the outer surface of the rope twisted or braided according to the mode. The composite braided rope is used for engineering with high requirements for abrasion resistance, high temperature resistance and impact fatigue resistance in shipping, spaceflight, military affairs, agriculture, industry and mine sports.

Description

technical field [0001] The invention belongs to textile ropes. Background technique [0002] Since the operating temperature of the existing ultra-high molecular weight polyethylene (UHMWPE) fiber ropes generally cannot exceed 100 degrees, the existing UHMWPE fiber twisted ropes are obtained by the following methods in order to improve the wear resistance and high temperature resistance: the surface of the rope is used during manufacture. Metal material coating, the defect of this method is that when it is used for a long time under high temperature conditions, the metal will transfer heat to the inner rope and cannot achieve the effect of wear resistance and high temperature resistance; and the coating material has great rigidity It can only be used in places with large bending radius, which limits the projects that require soft use. Contents of the invention [0003] The problem to be solved by the present invention is to provide a flexible wear-resistant and high-tempe...
