Agricultural anti-bird net with random colors

Abstract

The invention relates to an agricultural anti-bird net with random colors. The anti-bird net is prepared in the mode that segment color bamboo joint cellosilk is adopted and spun. Preparation of the segment color anti-bird net comprises the steps of preparation of the segment color bamboo joint cellosilk, yarn spinning, weaving and after treatment. A plurality of air permeable hollowed-out parts are formed in the cylinder wall of a spinning cooling cover shell which is used for preparing the segment color bamboo joint cellosilk, and cooling air flow of lateral blowing air runs through the spinning cooling cover shell through the air permeable hollowed-out parts, enters the spinning cooling cover shell and conducts cooling on spun filament; the air permeable hollowed-out parts surround thecylindrical spinning cooling cover shell and are arranged in a spiral line-shaped mode, the widths of the initial ends of the air permeable hollowed-out parts are larger than the widths of the tail ends of the air permeable hollowed-out parts, and the widths from the initial ends to the tail ends of the air permeable hollowed-out parts are changed in a linear mode in the directions of spiral linesof the air permeable hollowed-out parts; cooled spun filament strips are changed into a semi-solidified state; the spun filament which is located in the spinning cooling shell cover and is located atthe other positions cannot be sufficiently cooled by the cooling air flow of the lateral blowing air, and is still in a sticking and elastic 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
