Spunbond non-woven fabric has been widely used in the agricultural field, because of its good shading, permeability, degradation has been more and more favored by the majority of farmers, as a product to assist crop growth. But now, because of the strong selection of agricultural products market, the heat of market competition is also relatively large, non-woven agricultural products market will have a great prospect of development. Let’s see. The introduction of non-woven fabric technology in China is not long. In the development of off-season vegetable planting, non-woven fabric will be widely used.
Non-woven fabrics have been widely used in Japan, the United States, the Netherlands, Canada and other developed countries. Expect to achieve convenient management, mechanization or semi – mechanization.
The results show that the heat insulation effect of non-woven covering is more significant than that of covering curtain and heavier than that of covering curtain. From greenhouse and greenhouse with agricultural membrane together with multi-layer cover. This kind of non-woven greenhouse is also suitable for summer and autumn shade seedling and cultivation. Thick non-woven fabric (100? 200 g/m2) instead of straw curtains and MATS.
Generally used in greenhouse, greenhouse heat preservation curtain can also replace the straw curtain in the shed, enhance the heat preservation effect. Greenhouse 40-50g/m2 non-woven fabric with low air permeability, high shading, heavy quality. Can also be used as a small arch greenhouse, greenhouse and open greenhouse heat preservation curtain. It keeps you warm at night, raising the temperature by 0.7 degrees? Under normal circumstances, 20-30g/m2 thin non-woven fabric has high air permeability and light weight, which can be used for outdoor ground, greenhouse and greenhouse floating cover. The thickness of spunbond non-woven fabric is different, water permeability, shading and air permeability are different, covering methods and uses are also different.
Such as 20 grams of non-woven fabric per square meter, 30 grams of non-woven fabric per square meter, 40 grams of non-woven fabric per square meter. Non-woven fabrics are classified as thin, thick and thickened, usually measured in grams per square meter. Agricultural non-woven fabric is a new type of covering material with good air permeability, moisture absorption and light transmission.
Agricultural non-woven cloth includes crop protection cloth, seedling cloth, irrigation cloth, insulation curtain, its long service life is only 90 days. Decompose and store indoors for 8 years. Combustion non-toxic tasteless, no residual substances, less pollution to the environment, friendly to the environment. Waterproof, breathable, soft, non – combustible, non – toxic, non – stimulating, rich color and other characteristics.
If left outdoors, the material will decompose naturally. It is a new generation of environmental protection materials, with strong, breathable, waterproof, environmental protection, good flexibility, non-toxic tasteless, cheap and so on. Although it is cloth, it is called spunbond non-woven fabric. It is made by using water or air as suspension medium and using wet or dry paper machines (including chemical and plant fibers).
