Application of non-woven fabric in the shed

As a new type of covering and thermal insulation material, non-woven fabric is used in the production of shed vegetables and has achieved good economic benefits.　　 keep warm. Non-woven fabrics have lower transmittance to long-wave light than plastic films. Because the heat dissipation in the radiation area at night mainly relies on long-wave radiation, the coverage and heat preservation effect is outstanding.　　 Breathable and humidity control. The non-woven fabric is made of filaments stacked on each other into a net shape, has a high porosity, is breathable, permeable, and automatically adjusts humidity.　　 shading to cool down. Covered with colored non-woven fabric, it has the effect of shading and cooling. Non-woven fabrics of different colors have different shading and cooling effects. Black is better than yellow, and yellow is better than blue. Anti-aging. The agricultural non-woven fabric has undergone anti-aging treatment, the thicker the fabric, the lower the strength loss rate.　　After the practice of vegetable farmers, non-woven fabrics are mainly used in the production of shed vegetables in the following areas: 　　 is used on the bottom of the grass that is used as a 'two-layer' insulation material. Many shanty houses not only cover the surface of the shed, but also add a layer of non-woven fabric to the bottom of the grass thatch. According to vegetable growers, by adding'erdao' thermal insulation material (non-woven fabric), the thermal insulation performance of the shed can be significantly improved, which is 2 ℃-3 ℃ higher than that of the simple 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 grass thatch and extend its service life.　　 is used on the back wall of the greenhouse as a'slope protection' rainproof material. Use multiple non-woven fabrics to stitch together to wrap the entire back wall and fix it with steel wires to reduce heat loss from the back wall; it can prevent rain and snow, protect the wall; it can be covered and weeded to reduce pests and diseases entering the shed.　　Other applications. Used in the production of multi-membrane covered watermelon in the early spring arch shed, the non-woven fabric can be directly covered on the small arch shed in the arch shed, and the effect of heat preservation and cold protection is outstanding
