It is very non-woven, it is a pvc.
Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is made of oriented or random fibers. It is a new generation of environmentally friendly materials, which are moisture-proof, breathable, flexible, light, non-combustible and easy to decompose. It is non-toxic, non-irritating, rich in color, low in price and recyclable. For example, polypropylene (pp material) pellets are used as raw materials, which are produced by high-temperature melting, spinning, paving, and hot-rolling and continuous one-step process. It is called a cloth because it has the appearance and some properties of the cloth.
PVC is polyvinyl chloride, English abbreviation PVC (Polyvinyl chloride), is a vinyl chloride monomer (VCM) in the initiator of peroxides, azo compounds, etc.; or free radical polymerization under the action of light and heat A polymer obtained by polymerization of a reaction mechanism. The vinyl chloride homopolymer and the vinyl chloride copolymer are collectively referred to as vinyl chloride resins. Its material is a non-crystalline material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, weather resistance and excellent geometric stability. PVC is highly resistant to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, and is also not suitable for contact with aromatic hydrocarbons or chlorinated hydrocarbons.
