Embodiment 1

[0006] Embodiment 1: A kind of breeding cage or passive fishing gear with a diameter of φ5.0mm uses a small-sized high-performance mesh. The processing method consists of a luminescent yarn processing method, a marking yarn processing method, a nylon yarn processing method, a strand-making method and a mesh-making method. Composition, the specific implementation method is as follows:

[0007]Processing method of luminescent yarn: clean the mixer, mix luminescent pigment (such as PLO-7C luminescent pigment or RR-7 luminescent pigment), dry HDPE 5000S resin produced by Yangzi Petrochemical (melt index is 0.9g / 10min, if HDPE If the 5000S resin is damp, it should be dried in an oven or under sunlight before use), T30S PP resin produced by Daqing Petrochemical (melt index is 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, so as to ensure the normal drawing and reduc...

Embodiment 2

[0048] Embodiment 2: A kind of breeding net cage or passive fishing gear with a diameter D of 10.0mm is used. The processing method includes the processing method of luminous yarn, the processing method of marking yarn, the processing method of nylon yarn, the method of making strands and the method of making the mesh. Method steps.

[0049] Luminous yarn processing method: According to the luminous yarn processing method in Example 1, a PP / PE alloy luminous filament with good comprehensive performance (diameter 0.20mm, linear density 360dtex, breaking strength greater than 6.00cN / dtex, and elongation at break 11~ 22%, its softness and operability are better, and it can emit yellow-green or bright red fluorescence in the dark after being illuminated); the twisting machine twists 12 PP / PE alloy luminescent wires according to the twist of 98T / m Use the same twisting tension to form a luminous yarn (diameter 1.30mm) with a twist direction of "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 is more 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 14.7 and 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 processing method for a small-sized high-performance mesh used in breeding cages or passive fishing gear in the field of agricultural science and aquatic products. 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 assembled net cages or passive fishing gear. The so-called passive fishing gear refers to fishing gear that requires the movement of fish to catch fish, such as gillnets and fixed nets. The net outline is divided into cage net outline and fishing gear net outline according to the scope of use (according to whether fishing gear fishing requires fish movement can be subdivided into passive fishing gear net outline and active fishing gear net outline); according to the net outline diameter D specification, Divided into small size (4.0mm≤D<12.0mm) mes...
