Metallic carding cloth
These
are continuous. Self supporting flat wire structure in which teeth is cut at
the smallest spacing by process resembling a punching operation. They do not
need any base material or foundation. The wire as no knee. Metal surface of m/c
acts as metallic foundation If the teeth are relatively largely used or example
as in the Licker-in. Then the clothing is referred to as saw tooth clothing
Now-a-days the Licker-in, main Cylinder & doffer are without exception
clothed with metallic clothing. The application f metallic card clothing onto
spinning carding m/c has no limits & is used in the production of low medium
& high quality yans
Advantages
and Disadvantages of metallic carding cloth
Advantages
and Disadvantages of carding cloth are given bellow
Metallic Clothing Advantages:
1. Does not require
separate foundation material. The metal surface of the m/c works as foundation
2. Material As teeth &
foundation material are both metallic, there is no possibility of "teeth
loose".
3. Can choose any carding
angle
4. Does not require regular
grinding
5. No change of tooth angle
due to carding action and so no need of grinding. Again fibre does not -embed
to teeth & so need of stripping As a result, save much time.
6. Saved 3% good fibre
& increase production 18-20 % due to no need of stripping & grinding
Disadvantages:
1. Carding action is not
better due to less point density
2. Fibre damage is mere as the wire points are
metallic.
3. Difficult to repair in
the mill when a portion of it is worn out.
4. If any part of the wire
is damaged, then the total clothing is rewind.
5. Expensive
6. Not suitable to prepare
finer count
7. Liberates more fly
pollutes air
8. Requires higher starting
torque
