Non woven fabric really is a fabric like stuff made with
long fibers, attached with each other by mechanical, chemical, heat or solvent
treatment. Non woven Fabric is neither woven nor knitted. Non woven fabric is normally made by putting
small fibers together in the mould of a sheet or web & then binding them
either mechanically or chemically with an adhesive.
Non woven fabric is typically less strong due to not knit.
In recent years, non woven have become an alternative to polyurethane foam. Nonwoven fabric is broadly defined as sheet or web structures bonded collectively
by entangling fiber or filaments (and by perforating films) mechanically,
thermally or chemically. It is flat, porous sheets that are manufactured
directly from separate fibers or from molten plastic or plastic film. It is not
manufactured by weaving or knitting and do not require converting the fibers to
yarn. Typically, a certain percentage of recycled fabrics and oil-based
materials are used in non woven fabric. The percentage of recycled fabrics
varies based upon the strength of material needed for the specific use.
Nonwoven fabric is engineered fabrics that may be a limited life, single-use
fabric or a very durable fabric. Non woven fabric provides specific functions
such as absorbent, liquid repellent, resilience, stretch, softness, strength,
flame retardant, washable, cushioning, filtering, bacterial barrier and
sterility. These features are often combined to create cloth suitable for
specific work, while achieving a good balance between product use-life and
cost. It can mimic the appearance, texture and strength of a woven fabric and
can be as bulky as the thickest padding. In blend with other materials it
provides a spectrum of products with diverse properties, and is used alone or
as components of apparel, home furnishings, health care, engineering,
industrial and consumer goods. Non-woven fabric has its characteristics, which
are as follows:
Characteristics of Non-Woven Fabrics
Non-woven fabric can perform the following specific
functions:
It can be
used as blotting paper.
It can be
used asliquid repellent.
It can be
used asresilient.
It can be
used asstretchable.
It can be
used asdelicate.
It can be
used as flame retardant.
It can be
used as cleanable.
Non woven fabric as very good strength which enhances its
usability in various functions.
