Embodiment 1

[0006] Example 1: A small-size high-performance mesh processing method for a breeding net cage or passive fishing gear with a diameter of φ5.0mm consists of a luminous yarn processing method, a marking yarn processing method, a nylon yarn processing method, a strand-making method and a method Composition, the specific implementation is as follows:

[0007] Luminous yarn processing method: clean the mixer, before mixing the luminous pigment (such as PLO-7C type luminous pigment or RR-7 type luminous pigment), dry HDPE 5000S resin produced by Yangzi Petrochemical (melt index 0.9g / 10min, if HDPE If 5000S resin is damp, it should be dried in an oven or in the sun before use), T30S PP resin produced by Daqing Petrochemical (melt index of 2.1~3.9g / 10min), additives (such as turpentine or white oil) Screening treatment is carried out to remove the main impurities that may be mixed in the raw materials, to ensure the normal drawing process, and reduce the breakage rate of the finished ya...

Embodiment 2

[0048] Embodiment 2: A small-size high-performance mesh processing method for a breeding cage or passive fishing gear with a diameter D of 10.0mm includes a luminous yarn processing method, a marking yarn processing method, a nylon yarn processing method, a strand-making method, and a processing method Method steps.

[0049] Luminous yarn processing method: According to the luminous yarn processing method in Example 1, a PP / PE alloy luminous yarn with good comprehensive performance (diameter 0.20mm, linear density 360dtex, breaking strength greater than 6.00cN / dtex, breaking elongation 11~ 22%, its flexibility and maneuverability are good, and it can emit yellow-green or bright red fluorescence in the dark after exposure to light); the twisting machine will twist 12 PP / PE alloy luminous wires with a twist of 98T / m The twisting tension of the same size is used to twist the yarn into a luminous yarn (diameter 1.30mm) whose twist direction is "Z".

Abstract

The invention relates to a method for processing a cultivation net cage or a passive small-sized high-performance head rope for a fishing gear, in particular to a method for processing a head rope. The invention provides a method for processing a small-sized high-performance head rope for the fishing gear. The method adopts a stirring mill, HDPE resin, luminous pigment, an addition agent, PP resin, a coloring agent, a single-screw extruder, an electrical heating drawing machine capable of drawing twice, a filament take-up machine, a filament dividing machine, a wire twisting machine and a rope manufacturing machine. The method is characterized in that luminous yarn and marking yarn are manufactured; nylon yarn is manufactured by using nylon multifilaments of which the breaking strength ismore than 5.30 cN / dtex; the luminous yarn, the marking yarn, the nylon yarn and a strand core are manufactured to form 'S'-direction head rope strands of which the strand lay lengths are between 14.7and 28.7mm by using the rope machine in an 'S' direction; the three 'S'-direction head rope strands are twiddled into the cultivation net cage or the passive small-sized high-performance head rope for the fishing gear which is capable of emitting fluorescence in the dark in a 'Z' direction, wherein the lay length of the head rope is between 19.0 and 37.0mm, and the diameter of the head rope is between 4.0 and 12.0mm.

Description

Technical field [0001] The invention relates to a method for processing small-size high-performance nets for breeding net cages or passive fishing gear in the field of agricultural science and aquatic products technology. Background technique [0002] Nets are widely used in breeding cages or passive fishing gear in the field of agricultural science and aquatic technology, and their performance is directly related to the performance of the net cage or passive fishing gear after assembly. The so-called passive fishing gear refers to the fishing gear that requires the movement of the fish to catch the fish, such as drift nets and fixed nets. Nets are classified into cage nets and fishing gear nets according to the scope of use (the fishing gear can be divided into passive fishing gear nets and active fishing gear nets according to whether the fishing gear requires fish movement); according to the net diameter D specification classification, Divided into small size (4.0mm≤D<12.0...
