Problems solved by technology

There are mainly two methods currently used, one is to use plastic greenhouses for cultivation, and the other is to cover the crops with agricultural nets with a certain aperture, but the disadvantages of these two methods are: the use of plastic greenhouses is harmful to crops. The air permeability of the greenhouse has a certain influence, and because the plastic greenhouse fully covers the crops, it is often necessary to cover the crops that are sensitive to temperature and light when cultivating some crops that are sensitive to temperature and light. Agricultural nets have not been popularized across the country. The commonly used agricultural nets now only use ordinary weaving methods. The intersections of warp and weft are not fixed. , birds, etc., will easily cause the warp and weft silk to slip, and the mesh will deform, making it easy for insects to penetrate through the enlarged gap, affecting the growth of crops, and the deformed mesh will affect the uniformity of sunlight and the air permeability of crops. produce adverse effects

Embodiment 1

[0025] The skin layer is a ternary polymer composed of PE, PP, and 1-butene, with a melting point of 134°C, the core layer is made of PP, with a melting point of 164°C, and the skin layer content is 50%. No color masterbatch is added, and the conventional two-component The skin-core composite filament is obtained by the wire drawing process, and its fineness is 360 denier. It is woven into a rectangular mesh structure by plain weaving. The mesh size is 2mm in the length direction and 4mm in the width direction. The mesh is heat treated. , the heat treatment temperature is 150°C, and the time is 90s, so that the cortex of the warp and weft yarns is partially melted and the core layer remains unchanged, so that the warp and weft yarns contact and bond firmly at the intersection points. At this time, the strength of the net is 320N / 50mm, the elongation at break reaches 28%, the opening ratio of the mesh reaches 85%, and the light transmittance reaches 93%.

Embodiment 2

[0027] The cortex is made of high-density PE with a melting point of 132°C, the core layer is made of PP with a melting point of 165°C, and the cortex content is 50%, and transparent color masterbatch is added to the cortex, and the skin-core composite fiber is obtained through a conventional two-component wire drawing process. Silk with a fineness of 450 denier is woven into a square mesh structure with a leno weaving method. The side length of the mesh is 3mm. The mesh is heat treated at a temperature of 144°C for 75s. When tested, the strength of the net is 350N / 50mm, the elongation at break is 26%, the opening ratio of the net is 84%, and the light transmittance is 95%.

Embodiment 3

[0029] The cortex is a binary polymer composed of PE and PP, with a melting point of 132°C. The core layer is made of PP, with a melting point of 163°C, and the cortex content is 40%. Green color masterbatch is added to the cortex, and it is drawn by conventional two-component wire drawing. The skin-core composite filament obtained by the process has a fineness of 360 deniers, which is woven into a square hole-like mesh structure by the weaving method of the leno structure, and the side length of the mesh is 1 mm. 150°C for 80s. At this time, the strength of the net is 430N / 50mm, the elongation at break is 25%, the opening ratio of the net is 65%, and the light transmittance is 72%.

Abstract

The invention relates to a bonding-type agricultural net mainly formed by weaving sheath-core composite filament through a plain or leno weaving manner, subjecting the agricultural net after weaving to thermal treatment at a given temperature for a given time to melt the sheath layer and keep the core layer unchanged so as to realize contact at the position of the intersection point of warp and weft and firmed bonding, and further adding color master batch, anti-aging agent, uvioresistant stabilizer, flame retardant, antibacterial agent and other functional additives to the sheath layer. The agricultural net has the advantages of high strength, durability and weather resistance and firm structure, prevents the weft and the warp from easily sliding under the action of external force and prevents meshes from deforming. Therefore, the invention is applicable to aspects of insect prevention, bird prevention and hail suppression and the like in agriculture and has positive significance in guaranteeing the output and quality of crops.

Description

technical field [0001] The invention relates to a sticky agricultural net, in particular to an agricultural net which is woven by sheath-core composite yarns and is firmly bonded at the intersection of the warp and weft. The net can be used for insect control, Anti-bird, anti-hail, etc. Background technique [0002] In agricultural cultivation, effective prevention of pests, birds, and some natural disasters has always been an important part of research, which not only determines the yield and quality of crops, but also affects the appearance of crops. There are mainly two methods currently used, one is to use plastic greenhouses for cultivation, and the other is to cover the crops with agricultural nets with a certain aperture, but the disadvantages of these two methods are: the use of plastic greenhouses is harmful to crops. The air permeability of the greenhouse has a certain influence, and because the plastic greenhouse fully covers the crops, it is often necessary to c...
