polymers are transformed into endless filaments by melting and stretching, and then deposited on a wire mesh belt. The conversion of granulated into non woven takes place in a single production step.
Non-woven Fabrics are broadly defined as sheet or web structures boned together by entangling fiber or filaments(and by perforating films) mechanically, thermally or chemically. They are not made by weaving or knitting and do not require converting the fibers to yarn. Non-woven fabric is a fabric-like material made from long fibers,bonded together by chemical, mechanical, heat or solvent treatment. The binding process usually occurs through the pressing of fibers together with an adhesive, chemical binder,heat, ultrasonic pattern bonding. The popularity of non-woven fabrics is increasing day by day because of low cost, hygienic and biodegradable. But they can not be washed or reused properly.
