What are the applications of nonwovens in the agricultural field?
Non-woven fabric (Non-woven Fabric), also known as non-woven fabric, is a new type of environmental protection material, which has been more and more widely used in the agricultural field because it is breathable, non-toxic, non-irritating, wear-resistant and corrosion-resistant, etc. This paper will focus on the application of non-woven fabric in the agricultural field.
Agricultural mulching materials
As a kind of covering material, nonwoven fabric is widely used in agriculture, mainly for windproof, heat preservation, shading, moisturizing, rainproof, frostproof and insectproof.
Windproof: When nonwoven fabric is set up in the field as windproof net, it can effectively block the wind and sand, reduce soil loss, protect crops and improve crops' resistance to disasters.
Thermal insulation: In winter, the thermal insulation performance of nonwoven fabric is very good, which can effectively reduce the drop of soil temperature and thus protect crops.
Shading: In summer, the shading performance of nonwoven fabrics can effectively reduce the intensity of light and mitigate the photosynthesis of crops so that they are less likely to be harmed.
Moisturizing: In the dry season, nonwoven fabric can moisturize water, making the water in the soil less likely to evaporate and increasing the water content of the soil, thus protecting crops.
Rainproof: In the rainy season, nonwoven fabrics can effectively prevent rain from washing away, reducing soil erosion and protecting crops.
Frost protection: Nonwoven fabrics can effectively reduce frost damage in winter, thus protecting crops.
Insect protection: The "microporous" structure of nonwovens protects crops by allowing sunlight and rainwater to pass through, while effectively preventing insect-borne viruses.
Alternatives to film mulching
Agricultural film mulching is a common method in agricultural production, and its main function is to retain moisture and heat, increase soil temperature, prevent soil material loss, control pests, and promote crop growth. However, there are some problems with agricultural film mulching, such as pollution to the environment, harm to the soil and impact on human health. Therefore, nonwoven fabric, as an environmentally friendly and easily recyclable material, is widely used as a substitute for agricultural film mulching.
Geo-environmental restoration materials
As an environmentally friendly material, the application area of nonwoven fabric is not only limited to agriculture, but also widely used in environmental remediation, engineering construction, land reclamation and other fields. In rural areas, since there are often problems such as abandoned arable land and land degradation, nonwovens can be a good solution to these problems. Its application scenarios include.
1. Land remediation: For the land destroyed due to engineering construction and other reasons, nonwoven fabric can well restore the land, help soil consolidation, promote vegetation growth, accelerate the development of plant roots, and maintain the balance of water and nutrients.
2. Land reclamation: Nonwoven fabric can be a good substitute for traditional mulching materials to achieve soil insulation, water retention and consolidation, improve soil fertility and wind erosion resistance, so as to realize land reclamation.
Animal and plant feed packaging materials
Nonwoven fabric can also be used as packaging materials for feed materials, such as pharmaceutical extract packaging bags, dog food packaging bags, chicken, duck and goose feed bags, etc. Nonwoven materials have good tear resistance and environmental protection, which can effectively protect feed from pollution, moisturize and prevent moisture, and play an important role in the process of feed storage and transportation.
Greenhouse covering materials
As an agricultural production tool, the main role of greenhouse is to provide a stable temperature and humidity environment to protect plant growth. Therefore, the greenhouse covering material requires the highest quality for greenhouse. As a new, environmentally friendly material with good breathability and UV protection, nonwoven fabric can play a good role in greenhouse covering materials.
The above is the application of non-woven fabric in agriculture. Non-woven fabric is more and more widely used in agriculture, which greatly promotes the development and progress of agriculture and has a broad development space.
