Embodiment

[0041] The production process of a new sisal / synthetic fiber composite structure oil-containing steel wire rope rope core in the present invention is as follows: picking hemp→combing hemp (adding water)→drawing→spinning (adding oil)→winding warp→twisting strands (adding oil) → Twist the rope → Storage. Among them: the equipment models of each process: four lines of hemp, the models are L1 / 2, L3 / 4 respectively; five lines of drawing, respectively B1 / 2, B3, B4, B4; the spinning machine model is TGS0950; thread making The machine model is T1175, and the rope making machine model is M400. The specific operation is as follows:

[0042] The preparation method of described novel sisal / synthetic fiber composite rope core comprises the steps:

[0043] Step 1. Formation of sisal / polyester filament sirofield yarn: firstly pick up the sisal fiber, then go through four combing and five drawing frames, and then spin;

[0044] In the described spinning, the model of the spinning machine is ...

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...
