Abstract

The invention relates to a method for processing high-performance polyethylene twisting threads for waving netting or binding a steel rope, which belongs to the processing of polyethylene twisting threads and aims at improving the performance of the polyethylene twisting threads. The processing method adopts a stirrer, HDPE resin, paint, auxiliary agent, an extruder, a hot drawing machine, a thread collecting device, a thread dividing device and a thread twisting device. The method is characterized in that the HDPE resin is screened and then evenly stirred together with the paint and the auxiliary agent; the materials after being evenly stirred are extruded by the extruder, the extruded primary threads are cooled and pre-drawn, the pre-drawn threads are thermally drawn for two times at thehigh temperature, wherein water is taken as a heating medium in the first thermal drawing, edible oil is taken as a heating medium in the second thermal drawing, the threads are cooled by an airflowmethod after the total multiple of the twice thermal drawing is multiplied by 10.6-15.9 times, and a monofilament beam is divided into polyethylene monofilaments with the diameter of 0.15-0.28mm; 3-8polyethylene monofilaments are twisted into polyethylene single yarn on the S direction; 1-10 polyethylene single yarns are twisted into a polyethylene strand on the Z direction; and three polyethylene strands are twisted into a high-performance polyethylene twisting thread on the S direction.

Description

Technical field: [0001] The invention relates to a method for processing high-performance polyethylene twisted yarns for woven nets or stitched cables in the field of agricultural science and aquatic products. Background technique [0002] The production equipment for processing ethylene fiber twisted yarn includes bell and wing spindle twister, double-layer twister, ring twister and two-for-one twister. In the field of agricultural science and aquatic products technology, the woven mesh or the polyethylene twisted yarn of the cable is directly related to the performance of the mesh, cable and netting used in fishery engineering. The mesh is a mesh structure of a certain size woven by the wire The netting is also called mesh; the cable is the general name for the rope on the fishing gear. In order to meet the various needs in the field of aquatic technology, the properties of the polyethylene twisted yarn, the form of the package, and the color of the matrix material used can be...
