- About Us
Non-woven fabricsare mostly made of polypropylene (pp material) pellets, which are produced by a one-step method of high-temperature melting, spinning, laying, and hot-pressing.
The three major fibers used in the production ofnon-woven fabricsare polypropylene (62% of the total), polyester (24% of the total) and viscose (8% of the total). From 1970 to 1985, the use of viscose fiber in the production of non-woven fabrics accounted for more. However, in recent years, the use of polypropylene fiber and polyester fiber has become dominant in the fields of hygienic absorbent materials and medical textiles.
Needle-punched non-woven fabricsare made of fiber materials, which can be mixed with a variety of fibers. Commonly used raw materials are polyester fiber, viscose fiber, polypropylene fiber, etc.;spunlace non-woven fabricsare generally mixed with polyester fiber and viscose fiber;spunbond Non-woven fabricsmostly use polypropylene (pp material) pellets as materials; meltblown fabrics mainly use polypropylene as the primary material.
