MODERN DEVELOPMENTS
IN CARDING

2. The History:
In 1748 Lewis Paulof Birmingham, England developed the hand driven
carding machine . The name card hasits origin from the Latin "Carduus". Itkeeps an eye on
thorn, the spiked product of which was utilized for culling fibred separated in before time.
DEFINITION:
Carding is characterized as the decrease of entangled mass of
strands to cloudy web by working them between two firmly dispersed generally moving surfaces
dressed with sharp focuses. Itis a preparatory procedure in spunyarn technology soon after
blow room process.
STEPS IN CARDING:
Opening to individual fibers: The blow room just opens the RAW
material to groups where as the card opens it to the phase of individual strands. Thisenables
the eliminations of impurities andgood performance of the other operation.
Elimination of impurities:Impurities are mostly eliminated in taker
in and a small portion of it is elim inated by flat stripping. Modern card removes 80 – 90%
impurities from lap and sliver contains only 0.05 – 0.3% foreign matter.

3. Elimination of dust:Carding process removes dust aswell as micro
particles by significant friction.
Disentangling of neps: Blow room increment neps from machine to
machine, however card decrease it to a little erosion. The card does not expel neps but rather
unravels it by opening them. Unraveling procedure of neps can be done by Closer spacing
between the clothing, sharper clothing, optional speed of taker in, low doffer speed etc.
Fiber blending: The card barely enhances long term mixing as the
habitation time of the material in the machine is too short. The card enhances navigate mixing
and fiber with fiber blending.
ACTIONS OF CARDING MACHINE:
The following 4 actions take place in a carding machine:
1. Combing action;
2. Carding action;
3. Stripping action;
4. Doffing action.
COMBING ACTION:

4. Combing action takes place between feed roller and taker in. Here the direction of the
two surfaces is the same. Combing is the process of straightening and parallelization of fiber
and the removal of short fibers and impurities by using a comb or combs which is assisted by
roller and brushed.
CARDING ACTION:
Carding action takes place between flat and cylinder. In carding, the direction of wire in
two surfaces is opposite. The moving direction of roller are also opposite. One roller is slower
and the other is fast. So carding action is known as point against point action.
STRIPPING ACTION:
Stripping action takes place between Taken-in and Cylinder or else in between Doffer
and Stripper. In stripping action wire direction will be same. One roller will be faster than
another. So stripping action is also known as “Point back point” action.
DOFFING ACTION:
This action takes place between cylinder and doffer. In this place fiber is transferred
from cylinder to doffer. Low speed doffer is called fiber from high speed cylinder and makes a
condensed web for formation of sliver.
