Characteristics Of Non-woven Fabrics in Agricultural Applications

The application of non-woven fabrics in greenhouses has the following advantages:
Insulation:
The transmittance of non-woven fabrics to long-wave light is lower than that of plastic films. Because the heat dissipation in the radiation area at night mainly depends on long-wave radiation, the effect of covering and heat preservation is outstanding.
Ventilation and humidity control:
The non-woven fabric is made of filaments stacked on top of each other to form a net, which has a high porosity, is breathable, water-permeable, and can automatically adjust the humidity.
Shading and cooling:
It is covered with colored non-woven fabric, which has the function of shading and cooling. Non-woven fabrics of different colors have different shading and cooling effects. The shading effect of black is better than yellow, and yellow is better than blue.
Anti-aging:
Agricultural non-woven fabrics have undergone anti-aging treatment, and the thicker the fabric, the lower the loss rate of strength.
Through the application practice of vegetable farmers, non-woven fabrics are mainly used in the following aspects in the production of greenhouse Vegetables:
Used at the bottom of thatch as a "secondary" insulation material. The surface of the greenhouses of many shantytowns is not only covered with grass thatch, but also added a layer of non-woven fabric at the bottom of the grass thatch. According to vegetable growers, by adding "secondary" insulation materials (non-woven fabrics), the insulation performance of the greenhouse can be significantly improved, which is 2°C-3°C higher than that of simply covering grass thatch, which is conducive to the growth of vegetables. In addition, the application of non-woven fabrics on the shed using the roller shutter machine can also protect the thatch and prolong its service life.
