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