Various applications of spunbond nonwoven fabrics in the grain industry

Crop Coverage and Seedling Protection

Spunbond non-woven fabric can accelerate soil warming and reduce water evaporation by covering seedbeds and seedlings, while also resisting frost (as low as -3 ° C to -7 ° C) and pest infestation. This lightweight material (such as 17gsm) can also form a microclimate, promote rapid crop growth, and is particularly suitable for the early seedling stage of grain crops such as wheat and rice.

Grass and insect control management

Spunbond non-woven fabrics with a density of 30gsm or higher can effectively inhibit weed growth, reduce herbicide use, and prevent birds and insects from damaging food crops. Its breathability allows for the infiltration of irrigation water and fertilizers, while avoiding the risk of contamination from direct contact with pesticides.

Thermal insulation and extreme weather protection

In the scenario of grain storage or open planting,42gsm non-woven fabrics or more can resist short-term frost, hail and rainstorm, and protect grain piles or mature crops from extreme weather damage. For example, covering the top of a grain silo or open-air grain stack can maintain a stable temperature and humidity of 34.

Environmentally friendly packaging and composting applications

PLA（ Biodegradable spunbond non-woven fabric can be used for grain packaging (such as grain bags, seed bags), and its durability combined with biodegradable properties reduces plastic pollution. After disposal, it can be directly composted and decomposed, suitable for organic agriculture and green food industry chain.

Special scenario for rice seedling cultivation

Lightweight non-woven fabric (25gsm) is widely used in rice seedling cultivation. Covering the seedling field can reduce the temperature difference between day and night, lower watering frequency, and improve seedling survival rate through dust-proof function. Its acid and alkali resistance is also suitable for long-term exposure to paddy field environments.

Dust prevention and antibacterial properties of grain silos

High density non-woven fabric (60-80gsm) can be used as a lining or covering layer inside grain warehouses to suppress dust flying and reduce mold growth, ensuring the hygiene and safety of the storage environment.

Application scenarios

In the main rice producing areas of the middle and lower reaches of the Yangtze River, 25gsm spunbond non-woven fabric is widely used for rice seedling cultivation and covering. By replacing traditional plastic films, this technology solves the problems of large temperature differences between day and night and low seedling survival rates.

Technical Details

Material characteristics: 25gsm lightweight non-woven fabric has breathability, water resistance, and acid and alkali resistance, and can directly cover the surface of rice fields, forming a microclimate environment.

Operation process: After sowing, lay non-woven fabric, press the edges with soil, and use drip irrigation system to achieve precise moisture control. After the seedlings grow to the 3-leaf stage, remove the cloth and there is no need for secondary transplanting.

Implementation effect

Increasing production and reducing costs: Experiments have shown that non-woven fabric coverage increases rice germination rate by 15%, seedling survival rate by 20%, and reduces manual watering frequency by 50%.

Environmental advantages: Compared to plastic film, biodegradable non-woven fabric avoids soil pollution and reduces the use of herbicides by 30% during seedling cultivation.

Industry Promotion

This technology has been included in the “Guidelines for Green and Efficient Cultivation Techniques of Rice” issued by the Ministry of Agriculture and Rural Affairs. By 2024, it will be promoted in more than 5 million acres in Hubei, Hunan and other areas, helping to increase the average yield of rice by 8% -12% per acre.

Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
