What raw materials are needed to produce and process non-woven fabrics?

Non-woven fabric is a kind of textile products commonly used in medical and sanitary materials. Non-woven fabrics are needed to produce masks. Because of the impact of this epidemic, people have also begun to pay attention to the raw materials for the production and processing of non-woven fabrics. The raw material for spinning fabrics is only polypropylene, which is not the case. In fact, there are three main types of raw materials for the production and processing of non-woven fabrics. According to the advantages and disadvantages of each raw material, the processing cost and sales price of non-woven fabrics are often different.　　 non-woven fabrics are mostly made of polypropylene (pp material) pellets as raw materials, which are produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing.　　The three major fibers used in the production of non-woven fabrics are polypropylene (62% of the total), polyester (24% of the total) and viscose (8% of the total). From 1970 to 1985, viscose fiber was used most in the production of non-woven fabrics. However, in the past five years, polypropylene fibers and polyester fibers have become dominant in the fields of hygienic absorbent materials and medical textiles.　　 There are many materials of non-woven fabrics, which are mainly distinguished by the purpose. Here I will briefly explain, the materials are polyester, polypropylene, aramid, acrylic, nylon, composite, ES, 6080, vinylon, spandex, etc., I said they are all fibers. The sales price of non-woven fabrics produced by different materials and processes varies greatly. For the upstream of the non-woven fabric industry, polypropylene, polyester, viscose fiber, polyester and other raw materials are highly dependent on foreign sources. Affected by the epidemic, there are problems in the supply of non-woven fabrics. Various production and processing non-woven fabrics The transportation of cloth raw materials is blocked, and the supply of non-woven raw materials is tight, which has led to the continuous increase in the price of non-woven fabrics!
