Introduction to the advantages of agricultural non-woven fabrics
The transmittance of non-woven fabrics for long-wavelength light is lower than that of plastic films. Because the heat dissipation in the radiation area at night mainly relies on long-wave radiation, the covering effect is outstanding.
Breathable and humidity control:
The non-woven fabric is made of filaments laid on each other into a mesh, with a high porosity, breathable, water-permeable, and automatically adjusts humidity.
Shading and cooling:
It is covered with colored non-woven fabric, which has the function of shading and cooling. Different colors of non-woven fabrics have different shading and cooling effects. The shading effect of black is better than yellow, and yellow is better than blue.
Agricultural non-woven fabrics have undergone anti-aging treatment, the thicker the fabric, the lower the strength loss rate.
Through the application practice of vegetable farmers, non-woven fabrics are mainly used in the following aspects in greenhouse vegetable production:
Used at the bottom of thatch as a 'secondary' thermal insulation material. The shed surface of many shacks is not only covered with grass thatch, but also adds a layer of non-woven fabric to the bottom of the grass thatch.
According to Wenzhou Xinyu Non-woven Fabric Co., LTD., by adding 'two layers' of thermal insulation material (non-woven fabric), the thermal insulation performance of the greenhouse can be significantly improved, which is 2℃ higher than that of simply covering grass- 3 ℃, which is conducive to the growth of vegetables. In addition, the application of non-woven fabrics on the shed where the roller shutter machine is used can also protect the thatch and prolong its service life.
This is an internationally recognized standard which acts as a form of guarantee that everything Wenzhou Xinyu Non-woven Fabric Co., LTD. does is managed to the highest quality standards.
