What Is Carding | Functions of Carding In Spinning

<

We know that; Fiber is the raw materials for make a completely sale able product in the market. In this regards fibers need to pass a sequence of processing. Final products may be yarn, fabric or cloth, to get this the first steps of processing is spinning.

Spinning of natural fiber may be carded, combed or rotor types. Generally cotton is the most common products all over the world. Cotton spinning process is completely different from synthetic fiber spinning methods.

Carding operation is done after blow room process. Blow room product is lap or chute, after carding we will get carded sliver. Carded sliver feeds to draw frame for making drawn sliver.

Carding may be defined as the reduction of an entangled mass of fiber to a filmy web by working between two closely spaced, relatively moving surfaces clothed with sharp wire points. The carding is the most important factor for spinning, for this reason carding is called the heart of spinning mill and “well carding is half spun”- demonstrate the immense significance of carding for the final result of the spinning operation.

Carding is done for both carded and combed yarn. For every types of yarn production carding is must. Followings are the functions of Carding:

  • Carding is done for the individualization of the fiber.
  • Parallelization of fiber also done by carding action.
  • Remaining impurities and dust are eliminated by carding action.
  • Neps of fiber also disentangled by carding action.
  • Short fibers are eliminated by carding action.
  • Fiber blending is done by carding action.
  • Fibers are oriented by carding action.
  • Sliver formation also done by carding action.
  • To facilities the next drawing frame action is another functions of carding.

The main functions of carding machine are mostly similar for all types of fiber. But shape of carding machine is different from one another. If we consider cotton carding machine and jute carding machine than we will find that both are different from one another. In cotton spinning carding is done in one machine but for jute spinning fiber needs to pass two carding machine one is breaker card another is finisher card.

Carding machine manufacturers are trying to improve the present features of carding machine. If carding is not perfect than it will affects the next process. Spinning efficiency also depends on well carding. For this reason one should gives most concern on carding of fiber.

So, Carding is essential for making carded, combed or rotor cotton yarn and others fiber.
