Non-woven fabrics have been produced in the early stages of the development of the petrochemical industry. At that time, they only used their softness and bulkiness for packaging, covering, filling, and other materials. Due to the rapid development of materials science, the application scope of non-woven fabrics has expanded to various fields of industry and commerce, civil engineering, medical treatment, agriculture and environmental engineering, and its existence can be seen everywhere.
Non-woven industry development
Non-woven fabric is a product of the petrochemical industry after the development of plastic cloth (membrane). Compared with plastic cloth (membrane), its characteristics are lightness and good ventilation. Its materials are mostly used in medical and sanitary materials and environmental protection, such as sanitary napkins, facial towels, and Filters, etc., which were later developed and applied in engineering such as process tubes. Agricultural origin non-woven fabrics are used in vegetable production to prevent cold damage.
The Medical Non Woven Fabric is different from the general plastic film or cloth in its production process. The basic materials are almost the same raw materials, such as PVC (polyvinyl chloride), PE (polyethylene), EVA (Ethylene Vinyl Acetate copolymer), PVA (polyvinyl alcohol), and so on.
The traditional plastic film is formed into a thin film after the plastic is melted and inflated. Basically, the film is continuous. The material extends indefinitely. The surface of the film does not have any pores. It is a completely impermeable film. Block the movement and exchange of any molecules on both sides.
After the expansion of the textile industry, chemical fibers, that is, artificial fibers made from the above-mentioned raw materials replaced most natural plant fibers and became the darling of the textile industry. But basically, these chemical fibers are still formed into cloth through the traditional warp and weft weaving.
The so-called Spunbond Non Woven Fabric is formed by intersecting the fibers on the same plane from various angles in all directions, instead of using traditional warp and weft methods. Compared with traditional woven fabrics, it has better material properties. At the same time, its production process can be done from raw materials to finished products in one go. The process of traditional weaving, drawing into fibers, and then weaving is saved, and the production cost is lower. In fact, non-woven fabrics have also been widely used in the apparel industry in recent years.
In recent years, due to the improvement of material science and the development of production technology, non-woven fabrics have become more diverse and used more and more widely. According to the characteristics of different materials, the Nonwoven Tablecloth produced can be seen everywhere in our life. The development of non-woven fabrics in agriculture is mainly due to their lightness, simple operation, low cost, diversity, and wide range of applications.
Application of non-woven fabrics in the agricultural industry
Non-woven fabrics were applied to agriculture, and were first used in Europe in 1978 as carrots to keep warm for early harvesting and to prevent TYLCV and whitefly).
The United States has also promoted the application of non-woven fabrics in agriculture, such as cantaloupe, sweet peppers, tomatoes, root vegetables, carrots, radishes, cabbage, lettuce, and other mulching cultivation. Agriculture Non Woven Fabric is mainly used for heat preservation, early harvest of cultivation, and insect control effect. Later, the difference in the properties of non-woven materials was used to cover the border surface, as a grass-proof mat, and to increase soil temperature and water retention. In addition, the water absorption of short fiber is also used to produce absorbent blankets, which are applied to the laying of nursery beds, so that the roots can fully absorb water. Or it can be used as the bottom medium for turf production, or even directly used as garden grassland for moisturizing, draining, and dividing the garden. There are also large woody plants such as garden trees and fruit trees in planting bags and container cultivation techniques. Or large trees such as fruit trees, the rhizosphere prevents weeds and moisturizes.
