Non-woven is directed or random fiber and composition, is a new generation of environmentally friendly materials, with moisture, breathable, flexible, lightweight, non-combustion, easily biodegradable, non-toxic irritating, colorful, inexpensive, recyclable and so on. Such as the use of polypropylene (pp material) pellets as raw materials, high temperature melting, spinning, shop classes, hot take-up from a continuous one-step production.
Non-woven fabric is formed which does not require spinning and weaving, but the short fibers or filaments of textile or random orientation support column structure formed web, and mechanical, thermal or chemical methods such as reinforcement made . Simply say is this: it is not a one interleaved by the yarn, knitting together, but the fibers are bonded together by direct physical methods. Non-wovens breaking the traditional textile principle, and has a short process, production speed, high output, low cost, versatile, sources of raw materials and more features.
The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless identified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.
