One, Material and Composition: Greening non-woven fabric is formed directly from high molecular fragments, short fibers, or long filaments through air flow or mechanical means, then reinforced by hydroentanglement, needlepunching, or hot rolling, and finally processed into a nonwoven fabric. According to composition, green non-woven fabrics can be categorized into various types such as polyester, polypropylene, nylon, spandex, acrylic, etc. Polypropylene is one of the commonly used raw materials for producing green non-woven fabrics, due to its light weight, non-toxic and non-irritating properties, and chemical resistance.
