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. It is the most important factor for spinning, for this reason, carding is called the heart of the spinning mill, and “well carding is half spun”- demonstrates the immense significance of carding for the final result of the spinning operation.
We know that; Fiber is the raw material for making a complete saleable 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 step of processing is spinning.
The spinning of natural fiber may be carded, combed, or rotor types. Generally cotton is the most common product all over the world. The cotton spinning process is completely different from synthetic fiber spinning methods.
This operation is done after the 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.
Functions of Carding Machine In Spinning Process
Carding is done for both carded and combed yarn. For every type of yarn production carding is a must. The following are the functions of the carding machine. They are-
- Firstly, carding is done for the individualization of the fiber.
- Secondly, parallelization of fiber also done by carding action.
- Thirdly, remaining impurities and dust are eliminated by carding action.
- After that, neps of fiber also disentangled by carding action.
- Short fibers are also eliminated by carding action.
- Therefore, fiber blending is done by carding action.
- Then, fibers are oriented by carding action.
- Sliver formation also done by carding action.
- Lastly, to facilities the next drawing frame action is another functions of carding.
The main functions of carding machines are mostly similar for all types of fiber. But the shape of carding machine is different from one another. If we consider cotton carding machines and jute carding machines then we will find that both are different from one another. In cotton spinning carding is done in one machine but jute spinning fiber needs to pass two carding machines one is the breaker card another is a finisher card.
Carding machine manufacturers are trying to improve the present features of the carding machine. If carding is not perfect then it will affect the next process. Spinning efficiency also depends on well carding. For this reason, one should give most concern to carding of fiber.
So, the carding machine is essential for making carded, combed or rotor cotton yarn and other fiber.

I am a student of standard 12 . I want to Copy the notes for my exam .
But I can’t.
Plz help me out..

It is very critical to understand how carding machines work and their importance in spinning mills. The way you have written about the features and importance of carding machine will help a lot of people who wants to understand the textile industry or are new to the industry. I came upon a company called Jumac Manufacturing that has the most modern equipment and facilities when it comes to spinning cans, and other spinning tools or machines. They are one of the leading spinning can manufacturers in India, so I would advise you to check them out.
