TI
FELT is a fabric produced
without spinning or weaving
by using
mechanical action to interlock fibres
to produce a homogeneous mass of
|
interlaced fibres. Wool fibres if subjected to heat, moisture and mechanical action,
will migrate along their axes, curl
and interlace with adjacent fibre to
form a
traditional Woollen felt. Other fibres
can be blended
with the wool fibres when
characteristics are required which are not obtainable
by wool alone, it is the wool
in the blend which must
supply the felting ability.
Needle
- Loomed felt can be produced from fibres without any natural felting ability
by using the penetrating and compressive action of barbed needles to
interlock
the fibres into a homogeneous mass. Such
felts can be made partly or wholly from
fibres such as Wool, Rayon, Polyester, Acrylic,
Polypropylene etc.
There
are a number of materials which are erroneously called "felt" because
they
have felt like appearance. Cotton
batting, roofing
felt, crimped paper are few
examples.
