Processing method of non-woven fishing net

Abstract

The invention discloses a processing method of a non-woven fishing net. The processing method is characterized by comprising the following steps: (1) initial fusion: grinding silicon dioxide, then baking, carrying out constant-pressure fusion on polyvinyl chloride resin, adding rosin, then adding modified silicon dioxide powder, and after standing at a constant temperature and a constant pressure,preparing resin mixture; (2) bamboo-fiber modification: placing bamboo fiber into a closed heating tank, introducing oxygen and nitrogen, heating and standing, and after cooling, preparing the modified bamboo fiber; (3) dipping: adding lobeline into water, stirring and dissolving, and then placing modified bamboo fiber for dipping; (4) fusion: fusing the resin mixture, then adding the dipped modified bamboo fiber and titanium dioxide, placing in a constant-temperature room for high-temperature standing, and then preparing a modified resin material; (5) net manufacture: firstly heating a net manufacturing mold, then after fusing the modified resin material, adding into the net manufacturing mold through a feeding port, and adopting a net manufacturing process to prepare the non-woven fishing net.

Description

technical field [0001] The invention belongs to the technical field of fishing net processing, and in particular relates to a processing method of a non-woven fishing net. Background technique [0002] Fishing nets are an important production tool for fishing. As early as ancient times, ancestors had already started to use coarse cloth and hemp as raw materials, and made fishing nets by simple rolling methods for fishing and hunting activities. The use of fishing nets has greatly improved production. Efficiency has also made important contributions to the reproduction and development of human beings and the evolution of civilization. With the development of science and technology, the types and materials of fishing nets are constantly updated, and their mesh density and firmness have been greatly improved, which greatly improves the operating efficiency of human fishing; however, the mesh density of fishing nets is increasing. Shrinking, overfishing operations are becoming ...

Problems solved by technology

With the development of science and technology, the types and materials of fishing nets are constantly updated, and their mesh density and firmness have been greatly improved, which greatly improves the operating efficiency of human fishing; however, the mesh density of fishing nets is increasing. Shrinking, overfishing operations are becoming more and more serious, seriously affecting the reproduction of fish in rivers, lakes and seas, a large number of fish species have disappeared from the world, and the requirements for fishing operations have entered the judicial scope to limit overfishing; and at present, the processing of fishing nets mainly Depending on the weaving method, the specifications of the produced meshes are not uniform, the fluctuation is large, and the weaving process is costly.
