The fabrics which are produced directly from
bonding or entangling the fibres or filaments are called non-woven fabrics. The
bonding is done by mechanical, ther-mal or chemical means. Non-woven can be
divided into durable, non durable or disposable and semi durable types. The
properties of non-woven fabrics vary because they are made with different type
of fibres in different methods, depending upon the end product.
Non-woven are grouped based on the method of
production and life of the fabric. Based upon the production non-woven are
grouped as felts and bonded fabrics.
Based on non-woven fabrics quality they are
classified as durable, non durable, dis-posable and semi durable types. There
are two main types of non-woven namely felts and bonded fabrics.
Felt fabrics are made by interlock-ing of fibres
by any suitable mechanical or chemical method, with action of moisture and
heat. The basic techniques of fabric construction like weaving, spinning and
knitting are not used. Bonded fabric can be described as fibres compressed by
pres-sure and heat.
The properties of non-woven fab-rics vary because
they are made with dif-ferent types of fibres in different methods, depending
upon the end product.
Felts are used in home furnishing and bonded
fabrics are used in sanitary pads and diapers. Durable non-woven are used for
cap, interlining and interfacing for home furnishing, upholstery, carpets and
filters. Disposable non-woven are fabric which can be used only once like
napkins, surgical and industrial masks, ban-dages
and towels. Semi durable non-woven are used for shirts, curtains, bags, lining
material, wicks backing fabrics for picture frames, ribbons, hospital bed
linens and operation theatre clothes. (Figure 5.16)
