Agricultural non-woven fabrics help green vegetables thrive

Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers and is a new generation of environmentally friendly materials. 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, and recyclable. It has a wide range of applications in many fields. In recent years, non-woven fabrics, as a new type of covering and thermal insulation material, have been used in the production of shed vegetables and have achieved good economic benefits. The application of non-woven fabrics in the shed has the following advantages: Thermal insulation: 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 moisture-regulating: The non-woven fabric is made of filaments that are laid on each other to form a net, with high porosity, breathable, water-permeable, and automatic humidity control. Shading and cooling: Covered with colored non-woven fabric, which 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: 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 aspects: used on the bottom of the grass thatch as a'secondary' insulation material. Many shanty houses not only covered the grass thatch, but also added a layer of non-woven fabric to the bottom of the grass thatch. According to the vegetable grower, by adding'erdao' thermal insulation material (non-woven fabric), the thermal insulation performance of the shed can be significantly improved, which is 2°C-3°C higher than that of the simple covering grass thatch, which is beneficial 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. Used on the back wall of the greenhouse as a'slope protection' rainproof material. Wrap the entire back wall with multiple sheets of non-woven fabric stitched together, and fix it with steel wires to reduce the heat loss of the back wall; it can prevent rain and snow and protect the wall; it can be covered and weeded to reduce pests and diseases entering the shed. Other applications. Used in the production of early spring arched watermelon covered by multiple membranes, the non-woven fabric can be directly covered on the small arched shed in the arched shed, which has outstanding thermal insulation and cold-proof effect.
