Novel sisal/synthetic fiber composite structure oil-containing steel wire rope core and preparation method thereof

Abstract

The invention discloses a novel sisal / synthetic fiber composite structure oil-containing steel wire rope core and a preparation method thereof. The method includes the steps of 1, formation of sisal / polyester sirofil yarn; 2, formation of high-strength, high-modulus and low-elongation polyester filament yarn; 3, formation of ultrahigh-molecular-weight polyethylene filament yarn; 4, formation of sisal / polyester sirofil yarn and polyester yarn plied yarn; 5, formation of sisal / polyester sirofil yarn and ultrahigh-molecular-weight polyethylene filament yarn plied yarn; 6, formation of the novel sisal / synthetic fiber composite structure steel wire rope core. According to the method, sirofil spinning is adopted in the spinning process, the high-strength, high-modulus and low-elongation polyester filament yarn and the ultrahigh-molecular-weight polyethylene filament yarn are added in the plied yarn and rope making process, and an online oiling device is additionally arranged in sisal spinning and yarn making equipment. Ultrahigh-molecular-weight polyethylene filaments in the yarn are pretreated, and polyester filaments and the ultrahigh-molecular-weight polyethylene filaments with special sections are adopted.

Description

technical field [0001] The invention belongs to the field of preparation of sisal rope cores, and in particular relates to a novel sisal / synthetic fiber composite structure oil-containing steel wire rope core and a preparation method thereof. Background technique [0002] The traction wire rope is generally a circular strand structure, mainly composed of steel wire, rope strands and rope core. Steel wire is the basic component of steel wire rope, which requires high strength and toughness (including flexibility). The steel wire rope strands are twisted by several steel wires, and the steel wire is the basic strength unit of the steel wire rope; the steel wire rope with the same diameter of each strand twisted by steel wires, the more strands, the higher the fatigue strength. The rope core is a flexible mandrel around which the strands are wound, usually made of sisal or synthetic fibers, which supports and holds the rope and stores lubricant. [0003] The traction wire rop...

AI Technical Summary

Problems solved by technology

However, the surface of the rope core processed by natural fiber has many burrs and many production processes, which affect the production efficiency and increase the production cost. However, the steel wire rope core produced by synthetic fiber has problems such as insufficient oil content.
