In
carding m/c, different parts (ie. Licker-in, Cylinder. Doffer & flats) are
covered with different typ of wire which are known as card clothing.
To
cover the surface of Licker-in Cylinder doffer & flat carding m/c with the
help of a number of unlimited fine, closely spaced & specially bented wire
is call card clothing.
The
wire points are inserted on the m/c surface by means of a base material or

Types of carding clothing:
Card
clothing is divided into three group
1. Flexible clothing
2. Semi-rigid clothing.
3. Metallic clothing
Flexible carding clothing
These
have hooks of round or oval wire set into elastic, multiply cloth backing. Each
hook is U-shape & is formed with a knee that flexes under bending load
& returns to its original posit the load is removed. Flexible clothing is
used in cylinder flats & doffer. In short staple spinning r clothing is now
found only in the stripping roller
Advantages:
1. Higher point density,
so better carding action.
2. Fibre damage is less due
to flexible wire point
3. Only the damaged part of
the clothing is needed to be prepared
4. Exerts desirable force
on cotton causing good carding
5. Less expensive
6. Finer varn count can be
prepared. Of good
Disadvantages:
1. Requires textile fabric
or rubber as foundation material.
2. The wires can be
loosened
3. Production less due to
stripping
4. Neps regular grinding
5. Wire& foundation
material may get damage because of they are both flexible
6. Fibre becomes lose for
grinding action
7. Any carding angle cannot
be chosen.
