The non-woven fabric has no warps and wefts, is very convenient to cut and sew, is light in weight and is easy to shape, and is formed by only carrying out directional or random arrangement on textile short fibers or filaments to form a fiber web structure and then reinforcing by adopting mechanical, thermal bonding or chemical methods. Rather than being interwoven and knitted together from one yarn to another.

The non-woven fabrics have wide application range and are classified into spunlaced non-woven fabrics, heat-seal non-woven fabrics, pulp air-laid non-woven fabrics, wet non-woven fabrics, spun-bonded non-woven fabrics, melt-blown non-woven fabrics, needle-punched non-woven fabrics, stitch-bonded non-woven fabrics and the like.
