Non-woven fabrics are manufactured through various processes and can be classified based on their production methods. One common type is spunlaced non-woven fabric, which uses high-pressure micro-water jets to entangle fibers in one or more layers of a fiber web, resulting in a strong and durable material.
Another method is heat sealing, where hot-melt adhesives are added to the fiber web and then melted and cooled to form a cohesive fabric. Pulp air-laid non-wovens, also known as dry paper or clean paper, use air-laid technology to separate wood pulp fibers and then bond them using airflow, creating a soft and absorbent material.
The wet method involves suspending fibers in water, mixing different types of fibers, and forming a wet web that is then pressed and dried into a fabric. Spunbond non-wovens are made by extruding polymers into continuous filaments, laying them into a web, and then reinforcing them through thermal, chemical, or mechanical bonding. Melt-blown non-wovens involve extruding molten polymer into fine fibers, cooling them, and then forming a network that is bonded into a fabric.
Acupuncture non-wovens are produced using a dry process where needles puncture the fiber web to interlock the fibers and create strength. Stitched non-wovens use a similar dry method, where yarns or fibers are stitched together with other materials like plastic sheets or metal foils to reinforce the structure.
Non-woven fabrics have a wide range of applications. In the medical field, they are used for surgical gowns, masks, diapers, sanitary products, and wipes. For home use, they serve as wall coverings, tablecloths, and bedding. In fashion, they are used as linings, batting, and synthetic leather bases. Industrially, they are used for filters, insulation, geotextiles, and packaging. In agriculture, they help protect crops, regulate temperature, and support irrigation systems. They are also used in everyday items like tea bags, oil-absorbing pads, and soundproofing materials.
What makes non-woven fabrics unique is their short production process, high efficiency, low cost, and versatility. They can be made from a variety of raw materials, including natural and synthetic fibers, making them suitable for countless applications. Their flexibility and adaptability continue to drive innovation across multiple industries.
