Non-woven fabrics have been widely used in the agricultural field. Due to their good shading, air permeability, and degradability, farmers have become more and more favored by farmers as an auxiliary crop growth product. But now that the agricultural product market can have greater selectivity and the heat of market competition is also relatively large, the agricultural product non-woven market will have great development prospects, so let's take a look. The introduction of non-woven technology in my country has not been long. In the development of vegetable cultivation in the off-season, non-woven fabrics will be widely used.
Non-woven fabrics have been widely used in developed countries such as Japan, the United States, the Netherlands, and Canada. Expect to achieve convenient management, mechanization or semi-mechanization.
According to research, covering the greenhouse with non-woven fabric is more effective than covering curtains, and it is heavier than curtains. Multi-layer covering in greenhouses and greenhouses together with agricultural films. This kind of non-woven greenhouse is also suitable for shade seedling cultivation and cultivation in summer and autumn. Thick non-woven fabric (100~200 g/m2) replaces straw curtains and straw mats.
Agricultural non-woven fabrics are generally used in large sheds, and the thermal insulation curtains of large sheds can also replace the straw curtains in small sheds to enhance the thermal insulation effect. The 40-50g/m² non-woven fabric for greenhouses has low permeability, high shading rate and heavier quality. It can also be used for thermal insulation screens in small arch sheds, greenhouses and open-air ground greenhouses. It has a heat preservation effect at night and can increase the temperature by 0.7~3.0°C. Generally, the thin non-woven fabric of 20-30 g/m2 has greater air permeability and ventilation, and is lighter in weight. It can be used for outdoor ground, greenhouse, and greenhouse floating surface coverage. The thickness of the non-woven fabric is different, the water permeability, the shading rate, the air permeability are different, and the covering method and use 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 and so on. Non-woven fabrics are divided into thin, thick and thickened types, usually in grams per square meter. Agricultural non-woven fabric is a new type of covering material with good air permeability, moisture absorption and light permeability.
Agricultural non-woven fabrics include crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc. It has a longest life span of only 90 days. It is decomposed and placed indoors for 8 years. It is non-toxic, odorless, and has no residual substances when burned, so it will not pollute the environment, so it is environmentally friendly. It has the characteristics of water repellent, breathable, soft, non-combustible, non-toxic, non-irritating, and rich in color.
If placed outdoors, the material will decompose naturally. It is a new generation of environmentally friendly materials, which is strong, breathable, waterproof, environmentally friendly, flexible, non-toxic, tasteless, and inexpensive. Although it is a cloth, it is called a non-woven fabric. It is made by wet or dry paper machine (including chemical fiber and plant fiber) under the condition of water or air as the suspension medium.
