[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

Embodiment 1
[0045] An agricultural anti-bird net with random colors, the anti-bird net is prepared by spinning segment-colored slub fiber, the preparation steps of the bird-proof net include: preparing segment-color slub fiber, thread weaving, and post-finishing; the segment-color bamboo The preparation method of section fiber filament may further comprise the steps:
[0046] (1) Drying of polyester slices, hot air drying of polyester slices and color masterbatch respectively; the drying process can also include a pre-crystallization process;
[0047] (2) The polymer slices and masterbatches are mixed in proportion and sent to the screw extruder. The screw extruder is divided into six zones. The first two zones are the feeding section, the middle two zones are the compression section, and the last two zones are the metering section. Mixing section: concave-convex anti-adhesion mechanisms are provided on the surface in contact with the polymer melt inside the screw extruder, and the concav...
Embodiment 2
[0062]Using semi-dull polyester chips as spinning raw material to prepare yarn and bird-proof net, its specific implementation process is the same as in Example 1, and the specific parameters are:
[0063] The temperature during spinning is 250 degrees Celsius, the initial pressure during spinning is 16mpa, and the density of spinneret holes is 3 holes / cm 2 , the diameter of the spinneret hole is 0.35mm, the wind speed of side blowing is 0.6m / s, and the range of wind speed fluctuation is ±0.6m / s.
[0064] According to actual needs, the specification of the single-ply yarn is 20s, and the specification of the double-ply yarn is 20 / 2s.
[0065] The finishing liquid includes 10 wt% of modified nitrile emulsion, 10 wt% of phosphates, and the balance is water.
[0066] In order to improve the appearance of the anti-bird net, the drying temperature is 90°C, the speed is 5m / min, the speed of shaping is 15m / min, and the temperature is 100°C.

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...
