This document provides an overview of non-woven fabrics. It defines non-woven fabrics as sheet or web structures bonded together by entangling fibers or filaments mechanically, thermally, chemically or through solvent treatment. The document discusses the history of non-woven fabrics and mentions some early precursors. It also outlines different types of non-woven fabrics based on materials used and manufacturing processes. Common applications of non-woven fabrics in various industries are also summarized.

4. Nonwoven is one type of fabric that is not made by weaving or knitting or
interlacing of yarn. Nonwoven fabrics are broadly defined as sheet or web
structures bonded together by entangling fibre or filaments (and by perforating
films) mechanically, thermally, solvent treatment or chemically. They are flat,
porous sheets that are made directly from separate fibres or from molten plastic
or plastic film.
"Non-woven fabrics are fibrous sheet or web structures
produced by bonding or interlocking fibers by
mechanical, thermal or chemical means."
5. In the 19th century, (when England was the leading textile
producing country), realizing that large amounts of fiber were
wasted as trim, a textile engineer named Garnett developed a
special carding device to shred this waste material back to fibrous
form. This fiber was used as filling material for pillows. The Garnett
Machine, though greatly modified, today still retains his name and
is a major component in the non-woven industry.
Later on, manufacturers in Northern England began binding
these fibers mechanically (using needles) and chemically (using
glue) into butts. These were the precursors of today's non-wovens.
