[0002] Non-woven fabrics are made of directional or random fibers and are a new generation of environmentally friendly materials. They are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. Non-woven hot pressing process technology is a common method for manufacturing non-woven products.
