What is Nonwoven Fabric ?
Nonwoven fabrics are broadly defined as sheet or web structures bonded 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. Nonwoven 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 fibres together with an adhesive, chemical binder, heat, ultrasonic pattern bonding. The popularity of Nonwoven fabrics is increasing day by day because of low cost & they are hygienic & they are easily disposal . But the can’t easily be washed or reused properly.
