This document provides an overview of nonwoven fabrics. It defines nonwoven fabrics as sheet or web structures bonded together without weaving or knitting, using mechanical, thermal or chemical processes. Some key points covered include: - Common uses of nonwoven fabrics in household, industrial, and medical applications. - Raw materials used like cotton, rayon, polyester and different fiber properties they provide. - General production steps for nonwoven manufacturing including bonding techniques like needle punching, hydroentanglement, adhesive bonding and thermal bonding. - Desired properties in bonding agents and different types of binders used.

4. 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.
