Objects of Carding Machine || Carding is The Heart of Spinning

OBJECT:

1.    Opening to individual fibres.

2.    Elimination of impurities.

3.    Elimination of dust.

4.    Removal of short fibre.

5.    Fibre blending.

6.    Fibre orientation.

7.     Sliver formation.

1.     Opening to individual fibre: Card opens the tufts into the stage of individual fibres, whereas the blow room only opens the raw materials into flocks. This is essential to enable the elimination of impurities and performance of the other operation to be achieved.

2.     Elimination of impurities: Elimination of the impurities of the fibre is mainly done in taker in zone. The degree of cleaning achieved by the modern card is very high, in the range of 80-95%. The overall degree of cleaning efficiency by the blow room & carding together is 95-99%., but carded sliver still contain 0.005-0.3% foreign matters.

3.     Elimination of Dust: The card also removes a large quantity of micro particles that are bound to the fibres produced in the blow room. Card is considered as the best dust removing zone.

4.     Removal of short fibre: Very small or fewer than 10% short fibres are removed from the card. Those short fibres can only be removed if those are pressed into the clothing.

5.     Blending of fibres: Intimate fibres with fibres mixing is achieved here for the formation of web and repeated rotation of the fibres in the main cylinder. It should be noticed here that, carding is the only machine for processing the individual fibres.

6.     Fibbers orientation: It is often attribute the effect of parallelizing. The card can be given the task of creating partial longitudinal orientation of the fibres.

7.     Formation of sliver: The main output of carding is sliver. Here sliver is formed to deposit the fibres material for further operation. It also done to transport from blow room to draw frame process.

Carding is The Heart of Spinning

• It’s one of most important process in the spinning mill. It is directly determines the final features of the yarn. In carding process, fibres are opened individually; more dust & impurities are removed here. Parallelizing & stretching of fibres are also done here. Fibre orientation & transformation of fibre into sliver are also done here. Since, all the major qualities of yarn are gained here, that’s why carding is called the “heart of spinning.”
