Embodiment

[0028] A new type of steel wire rope core and its production method, comprising the following steps: picking hemp→combing hemp (adding water)→drawing→spinning→twisting strands (soaked in oil)→twisting rope→storage; The system adopts the drafting system of TGS0950 sisal spinning machine, and its twisting system adopts a rubbing-roll type self-twisting spinning, twisting and winding system. The sliver is fed and drawn by the drafting system, and another chemical fiber filament is directly fed from the front roller, and its rubbing-roll type self-twisting spinning is twisted and then directly wound into a bobbin.

[0029] The self-twist spinning specifications of sisal and high-strength low-stretch polyester filaments are: 0.80m / g, of which: one is high-strength, high-modulus and low-stretch polyester filaments with a size of 3×900D / 24F, and the other is sisal strands;

[0030] Sisal and ultra-high molecular weight polyethylene filament self-twisting spinning specifications: 0.80...

Abstract

The invention discloses a novel steel wire rope core and a production method thereof. The production method comprises the following steps: picking up hemp, carding the hemp (adding oily water), drawing, spinning, twisting into strands (soaking with oil), twisting into a rope and warehousing. According to a spinning machine disclosed by the invention, a sisal spinning machine modified by a technology is adopted, a drafting part adopts a drafting system of the TGS0950 type sisal spinning machine, and the twisting part is modified into a twisting roller type self-twist spinning twisting and winding device; one of feeding raw materials adopts sisal fibers while the other one of the feeding raw materials adopts chemical fiber filaments, self-twist spinning of the chemical fiber filaments and the sisal fibers is implemented, and then thread twisting, oiling and rope making are carried out. High-strength high-modulus low-elongation polyester filament yarns and ultra-high molecular weight polyethylene filament yarns are respectively added in a spinning process, wherein the ultra-high molecular weight polyethylene filament yarns are pretreated, and the polyester filament yarns and the ultra-high molecular weight polyethylene filament yarns are trilobal structural sections. The invention provides a novel method for producing the steel wire rope core, the process flow is shortened, and surface burrs of yarns are reduced.

Description

technical field [0001] The invention belongs to the field of preparation of sisal rope cores, and in particular relates to a novel steel wire rope core and a production method. Background technique [0002] Self-twisting spinning is to hold two ends of two strands and twist them in the middle to form two false-twisted single yarns with alternating positive and reverse twists, and then put the two yarns close together in parallel, relying on the two yarns The torsional moment is self-twisted into a double-ply structure self-twisting yarn with self-twisting twist. The self-twisting spinning machine is mainly composed of four parts: feeding and drawing, twisting and winding. [0003] The process of self-twisting spinning machine feeds two yarns (roving or sliver) into the drafting mechanism, and the drafting mechanism drafts the two yarns to the required degree and outputs them from the front roller; a One sliver is drawn out from the front roller, and the other yarn is fed f...
