Method for processing medium-size mixed rope for fishing with warning function

Abstract

The invention discloses a method for processing a medium-size mixed rope for fishing with a warning function, which relates to processing of ropes for fishing. The invention aims to provide a method for processing a medium-size mixed rope for fishing with a warning function. The mixed rope is made from PP (polypropylene) resins, high-density polyethylene (HDPE) resins, luminescent powder and assistants. The invention is characterized by comprising the following steps: 36 blended modified polypropylene filaments with a warning function and 36 blended modified polypropylene monofilaments are doubled to form a Z-twist blended modified polypropylene single yarn with a warning function and a Z-twist blended modified polypropylene single yarn; the strand core is composed of 5 Z-twist blended modified polypropylene single yarns, the surface layer of the strand is composed of 7 Z-twist blended modified polypropylene single yarns with a warning function and 7 Z-twist blended modified polypropylene single yarns, and the 19 yarns are made into an S-twist strand of which the length of lay is 45.0-47.0mm; and 3 S-twist strands are twisted in a Z-twist mode to obtain the medium-size mixed rope for fishing with a warning function, the length of lay of which is 52.0-55.0mm.

Description

Technical field [0001] The invention relates to a method for processing fishing ropes in the technical field of agricultural science and aquatic products. Background technique [0002] Rope is an indispensable and important material for fishing gear or cage facilities in the field of aquatic technology, and its performance is directly related to the safety of fishing gear or cage facilities at night and the adaptability of fishing. There are many rope classification methods. According to their scope of use, they can be divided into fishing ropes, agricultural ropes, marine ropes and military ropes; according to their specifications, they can be divided into small-sized ropes with a diameter of 4.0 to 12.0mm (excluding ropes with a diameter of 12.0mm) , Medium-sized ropes with a diameter of 12.0~20.0mm (including ropes with a diameter of 12.0mm and a diameter of 20.0mm) and large-sized ropes with a diameter of 20.0mm or more (excluding ropes with a diameter of 20.0m), etc.; The c...

AI Technical Summary

Problems solved by technology

Medium-sized fishing ropes with a diameter of 12.0 to 20.0mm are widely used in fishery production. They can be used for binding ropes for stretch net fishing gear, mesh ropes for net cages and bags, pull ropes for net cages and bags, and Gillnet buoys are used for binding ropes, etc.; the existing fishing ropes are generally pure spinning ropes or non-modified mixed ropes of the same fiber and different shapes. Without warning signs, it may be damaged by passing ships, which will lead to the occurrence of fish escape accidents, which will bring economic losses to fishermen

The use performance of existing fishing ropes has defects, and its safety, warning function, and nighttime operation adaptability are poor, and it is difficult to meet the special needs of fishing gear or net cage facilities laid in water at night. Medium-sized hybrid ropes for fishing is an urgent technical problem to be solved in the field of aquatic technology
