Non-woven fabric is a kind of non-woven material. It is not interwoven and braided together by yarns one by one, but the fibers are directly bonded together through physical methods. Non-woven fabrics break through the traditional textile principles and have the characteristics of short process flow, fast production speed, high output, low cost, wide use and multiple sources of raw materials. It is moisture-proof, breathable, flexible, light, flame-retardant, non-toxic and odorless, low-priced, and recyclable, so it is widely used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, and medical , filling materials, etc.
The manufacturing process of non-woven fabrics involves forming fibers into a fiber network through spunbonding, melt-blown film or wet methods. This network is then cured through pressure, heat treatment, or chemicals to form the final nonwoven. Compared with traditional textiles, non-woven fabrics have many advantages, such as high strength, breathability, waterproofness, corrosion resistance, and relatively low cost. These properties make non-woven fabrics widely used in various fields. In the , it is often more breathable and lightweight while providing adequate barrier properties. Since the manufacturing process of non-woven fabrics does not require traditional textile processes, it is relatively more environmentally friendly in terms of energy and resource use. In addition, many non-woven fabrics can be recycled, reducing the impact on the environment. In agriculture, non-woven fabrics are used to cover plants to maintain heat, moisturize, and suppress weeds. This helps improve crop yield and quality.
