[0002] Non-woven fabrics, also known as non-woven fabrics, are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. For example, polypropylene pellets are often used as raw materials, and are produced in a continuous one-step process of high-temperature melting, spinning, laying, hot pressing and winding.
