Polypropylene resin.

Non woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth due to its appearance and certain characteristics.

Non woven fabrics have the characteristics of moisture resistance, breathability, flexibility, lightweight, non flammable, easy decomposition, non-toxic and non irritating, rich colors, low price, and recyclability. For example, polypropylene (PP) pellets are often used as raw materials and produced using a continuous one-step method of high-temperature melting, spinning, layering, and hot pressing and coiling.
