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.
