Nonwoven fabric is one of dry non-woven fabrics, also known as needle felt. Made of polyester and polypropylene raw materials, it is processed by appropriate hot rolling after repeated acupuncture. The short fibers are opened, combed, and laid into a fiber web, and then the fiber web is reinforced by a needle to form a cloth, and the needle has a hook. The fiber web is repeatedly pierced, and the hook tape is reinforced to form a needle-punched nonwoven fabric. The non-woven fabric has no warp and weft, and the fibers are disordered, and the warp and weft performance is not much different.


Typical products: non-woven fabrics for greenhouse insulation, road maintenance felts, synthetic leather base fabrics, needle-punched geotextiles, etc.
