[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...

[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
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...
