Problems solved by technology

[0003] At present, with the development of farming methods and scales, fiber nets have been used as the main material for breeding nets. The commonly used fiber nets in China mainly include chemical fiber nets such as nylon, polyester, and polyethylene. Nylon and polyester fiber nets are not only The strength is not high, it is easy to break, and the anti-microbial adhesion function is poor, resulting in the need for frequent maintenance and replacement

Abstract

The invention relates to an anti-biological adhesion fiber net with the stable size. A net body is made by braiding a net rope prepared from two fiber materials, an inner layer of the net rope is polyarylester filament, and an outer layer of the net rope is polyethylene filament. The net body is good in the comprehensive performance and is made by braiding a net rope prepared from two different fiber materials, the size of a fiber net body is stable, and the fiber net body further has good wear-resistance, strength, and anti-ultraviolet performance. At the same time, polymethylphenyl siloxane,glass beads, and nano-silica are added to prepare the polyethylene filament, the strength of the net body is further improved, meanwhile the surface of the net rope forms microscopic surface morphology after the treatment, and the effects of water and oil repellent and anti-biological adhesion are achieved.

Description

technical field [0001] The invention relates to the technical field of fiber nets for aquaculture or underwater protection, in particular to a size-stable anti-biological adhesion fiber net. Background technique [0002] my country is a big aquaculture country. The country actively encourages and supports the "blue granary" and vigorously develops aquaculture. my country is already one of the top ten largest mariculture countries in the world. The trend of sea farming will develop to the deep sea, and the scale of farming will be expanded, which will put forward higher requirements for the performance of the cages used for farming. [0003] At present, with the development of farming methods and scales, fiber nets have been used as the main material for breeding nets. The commonly used fiber nets in China mainly include chemical fiber nets such as nylon, polyester, and polyethylene. Nylon and polyester fiber nets are not only The strength is not high, it is easy to break, a...
