One, Material and Composition: Greening nonwoven 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 nonwoven 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 making green nonwoven fabrics, due to its lightweight, non-toxic and non-irritating, and chemical-resistant properties.
