Non woven fabrics are widely used in agriculture and horticulture, such as heat preservation, frost prevention, insect prevention, soil and water conservation, soilless cultivation, artificial vegetation, lawn protection, plant root protection, seedling cloth and so on.
The cloth like covering with good air permeability, moisture absorption and light transmittance has the functions of cold resistance, moisture retention, frost resistance, antifreeze, light transmission and air conditioning, and has the characteristics of light weight, convenient use and corrosion resistance. The thickened non-woven fabric can also be used for multi-layer covering due to its good heat preservation effect.
The width of super wide splicing non-woven fabric is 6.7 m, 8 m, 10 m, 16 m, 20 m, 30 m, 46 m, etc. it is spliced according to different requirements of customers.
The product weight is generally 17-18-20g, or according to the requirements of customers.
According to the research, the heat preservation effect of non-woven fabric for covering greenhouse is better than that of straw curtain, and it is lighter than straw curtain in weight, convenient in management, and it is expected to realize mechanized or semi mechanized uncovering by splicing non-woven fabric.
Non woven fabrics have been widely used in Japan, the United States, the Netherlands, Canada and other developed countries.
The introduction of non-woven technology in China is not long. At present, the types and specifications of products are less, the price is higher, and the quality is lower than that of foreign similar products. At the same time, the research and promotion of covering technology are not enough, so the promotion area is not large.
However, with the improvement of non-woven production technology and the further improvement of covering technology, agricultural splicing non-woven fabric will be widely used in the development of vegetable Off-season Cultivation.
