A random color agricultural bird prevention net

Abstract

An agricultural anti-bird net with random colors, the anti-bird net is prepared by spinning segment-colored slub fiber yarn, the preparation steps of the segment-color slub-proof net include: preparing segment-color slub fiber yarn, yarn spinning, weaving, post-processing tidy. Several air-permeable hollows are provided on the cylindrical wall of the spinning cooling shell for preparing segmented colored slub fiber filaments, and the side blowing cooling air flows through the several air-permeable hollows and enters the spinning cooling shell through the spinning cooling shell. The interior of the casing cools the as-spun yarn; the several air-permeable hollows are arranged in a spiral shape around the cylindrical spinning cooling casing, and the widths of the beginning ends of the several air-permeable hollows are larger than the widths of the tail ends , and the width from the beginning of the air-permeable hollow part to the width of the tail end changes linearly along the direction of the helix of the air-permeable hollow part; the primary filaments after this cooling become semi-solidified; The as-spun filaments located in other positions cannot be sufficiently cooled by the cooling airflow of the side blowing, and are still in a viscoelastic state.

Description

technical field [0001] The invention relates to the field of agricultural anti-bird technology, in particular to an agricultural anti-bird net with random colors. Background technique [0002] my country has a vast territory, rich species, and spans a variety of climate zones. The unique natural conditions make China one of the countries with the richest bird resources in the world. At present, there are more than 9,000 species of birds in the world, and China has more than 1,200 species, accounting for more than 14% of the world's birds. With the enhancement of people's awareness of environmental protection and the restoration of ecology, the types and numbers of birds are on the rise. The harm of birds such as sparrows, which feed on rice, beans, fruits and vegetables, to crops is gradually revealed. The dangers are becoming more and more obvious. They peck the freshly filled rice and immature fruits and vegetables in the breeding fields, and at the same time bring disea...

Problems solved by technology

[0008] However, ordinary anti-bird nets cannot provide a good visual protection effect, and it is not appropriate to simply set a visual model on the traditional net. Therefore, it is necessary to develop a new type of protective material to prepare the protective net, so that the protective net itself It has random and changeable visual effects, and also has the characteristics of net protection, which has the protective effect of synergy between visual protection and net protection
