China Wholesale Rollo De Tela Factories - Agriculture use PP Spunbond Nonwoven – Henghua Detail:
Application
1.Agricultural non-woven fabrics are generally made of polypropylene filament fibers by hot pressing. It has good air permeability, heat preservation, moisture retention and certain light transmittance.
2.It is a new generation of environmentally friendly materials, which has the characteristics of water repellency, breathability, flexibility, non-combustibility, non-irritating, and rich colors. If the material is placed outdoors and decomposed naturally, the non-woven fabric has a lower transmittance of long-wave light than plastic film, and the heat dissipation in the night radiation area mainly depends on long-wave radiation; so when used as a second or third curtain, it can improve the greenhouse , Greenhouse temperature and soil temperature have the effect of increasing production and income.
3.Non-woven fabric is a new covering material, usually expressed in grams per square meter, such as 20 grams per square meter non-woven fabric, 30 grams per square meter non-woven fabric, etc. The light transmittance decreases as the thickness increases. The air permeability of agricultural non-woven fabrics decreases with the increase in thickness, and increases with the increase of the external wind speed and the increase of the temperature difference between inside and outside. In addition to the influence of thickness and mesh size, the thermal insulation degree of agricultural non-woven fabrics is also related to external factors such as weather and covering form. The lower the outside temperature, the better the heat preservation effect; the better the heat preservation effect of covering in the greenhouse.
Application
Depending on its thickness, mesh size, color and other specifications, it can be used as heat preservation and moisturizing covering material, sunshade material, isolation bottom material, packaging material, etc.,
Different colors of non-woven fabrics have different shading and cooling effects.Generally, the thin non-woven fabric of 20-30 g/m² has high water permeability and air permeability, and is light in weight. It can be used for covering the floating surface in the open field and the greenhouse, and can also be used for the open field small arch shed, the large shed, and the thermal insulation screen in the greenhouse at night. It has the function of heat preservation and can increase the temperature by 0.7~3.0℃. 40-50g/m2 non-woven fabrics for greenhouses have low water permeability, high shading rate and heavier quality. They are generally used as thermal insulation screens in large sheds and greenhouses. They can also be used instead of straw curtain covers to cover the small sheds to enhance heat preservation. . Such non-woven fabrics for greenhouses are also suitable for shade seedling cultivation and cultivation in summer and autumn. Thickened non-woven fabric (100~300g/m²) replaces straw curtains and straw thatch, and together with agricultural film, can be used for multi-layer coverage in greenhouses and greenhouses.
