Non-woven fabrics, also known as non-woven fabrics, are a new generation of environmentally friendly materials. They are composed of oriented or random fibers. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, recyclable and so on. It is widely used in many fields.


In recent years, non-woven fabric as a new type of covering insulation material has been used in the production of greenhouse vegetables, and has achieved good economic benefits. The application of non-woven fabric in the shed has the following advantages:


Keep warm:


Non-woven fabrics have lower transmittance for long-wave light than plastic films. Because the heat dissipation in the radiation zone at night mainly depends on long-wave radiation, the covering insulation effect is outstanding.


Breathable humidity control:


Non-woven fabric is made of filaments laid on top of each other in a net shape, which has a high porosity, is breathable, water-permeable, and automatically adjusts humidity.


Shading and cooling:


Covered with colored non-woven fabric, it has the function of shading and cooling. Different non-woven fabrics have different shading and cooling effects. Black shading effect is better than yellow, yellow is better than blue.


 Anti-aging:


Agricultural non-woven fabrics have undergone anti-aging treatment, the thicker the fabric, the lower the strength loss rate.


After the application of vegetable farmers, non-woven fabrics are mainly used in the production of greenhouse vegetables in the following areas:


Used at the bottom of the grass as a "two-way" insulation material. Many shacks have not only covered the grass with the surface of the shed, but also added a layer of non-woven fabric to the bottom of the grass. According to vegetable farmers, by adding "two-way" insulation materials (non-woven fabrics), the insulation performance of the shed can be significantly improved, which is 2 ° C-3 ° C higher than simply covering the grass, which is beneficial to the growth of vegetables. In addition, the use of non-woven fabrics in the shed using the roller shutter machine can also protect the grass and extend its service life.


Used as a "slope protection" rainproof material on the back wall of the greenhouse. Using multiple non-woven fabrics stitched together to wrap the entire back wall and fix it with steel wire, it can reduce the heat loss of the back wall; it can prevent rain and snow, protect the wall; it can be covered with weeds to reduce the damage of diseases and insect pests into the shed.
