What raw materials are needed to process non-woven fabrics? The quality of non-woven fabrics has an important impact on the quality of non-woven fabrics. Therefore, the quality of raw materials must be strictly controlled during the production and processing of non-woven fabrics to avoid the process of non-woven fabric processing. Use inferior raw materials.
Non-woven fabrics mostly use polypropylene (pp material) pellets as raw materials, and 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 fiber (8% of the total). From 1970 to 1985, viscose fiber was used the 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.
Needle-punched non-woven fabric is a fiber material, which can be produced by mixing a variety of fibers. Commonly used raw materials are polyester fiber, viscose fiber, polypropylene fiber, etc.; spunlace fabric is generally a mixture of polyester fiber and viscose fiber; spunbond non-woven The cloth mostly uses polypropylene (pp material) pellets as the raw material; the melt blown cloth mainly uses polypropylene as the main raw material.
There are many materials of non-woven fabrics, which are mainly distinguished by what they are used for. 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.
