What is Carding Machine in Textile? Explained!

Wondering what is carding machine and don’t know its functions? This guide is here to help you figure it out.

By using a mechanical process called carding, locks and other clumps of fiber are broken up, and the individual fibers are then arranged so that they are roughly parallel to one another. Given that the cylinders are covered in clothing and are angled at various angles, the carding machine used in woolen spinning is more traditional.

Three cardinal actions—carding, stripping, and raising—are managed and influenced by these cylinders as they rotate at various speeds. The clumps are broken up and the fibers are separated from the clothing when the mixture is done properly.

So what does a textile carding machine do? We’ll go into great detail about it in this article for you.

What is Carding Machine?

Fibers that require a series of processing steps in order to produce yarn are used in carding machines. The spinning process begins at this point. The spinning process for textile fibers can be carded, and cotton is the most popular product worldwide because it differs greatly from other methods of spinning.

Generally speaking, all types of fiber are subject to the same carding machine’s primary function. Wool and cotton carding are available on the market, but they differ from one another.

Feature of Carding Machine

• working on flats in the cylinder’s reverse direction to increase action and improve web quality
• Cleaning rollers typically take the place of combs for flat stripping.
• Wool Carding machines reduce noise
• The carding machine has both continuous and multiple suction points that are located on the card.
• The carding machine’s front and back stationary flats as well as its carding section are installed underneath the licker.
• For the process of carding wool lapping, a carding machine is used.
• The parameters of electronic control and digital display are similar.
• Feed roller and doffer drive are used, along with an inverter-controlled system, to enable step-less speeds.
• best quality clothing with metallic card equipment.
• The web take-off device with a double apron system allows visual inspection for a stunning appearance.
• There are automatic stop-motion devices.

Objects of Carding Process in Spinning

Some important purposes of the spinning process have been pointed out below:

1. Opening into independent fibers,
2. Extracting of neps,
3. Removal of short fiber,
4. The blending of fibre,
5. Fibre orientation,
6. Formation of sliver.

All the above purposes have explained in the following:

1. Opening into independent fibres: Carding is a crucial step in the spinning process. In this instance, card allows flocks to enter the stage of individual fibers. Because the blow room only pens the raw materials into flocks. The other processes will be flawless if this one is flawless. This method aids in the purging of various impurities.
2. Extracting of neps: Card does this by removing fewer neps from the blow room. It should be noted that cards do not completely get rid of neps; rather, they are mostly opened out.
3. Removal of short fibre: The card has very few short fibers—less than 10%—removed from it. Only if they are pressed into the clothing can those short fibers be eliminated.
4. Blending of fibre: The formation of the web and repeated rotation of the fibers in the main cylinder are achieved here by intimate mixing of the fibers. It should be noted that the only machine capable of handling individual fibers is the carding machine.
5. Fibre orientation: The task of partially orienting the fibers longitudinally can be delegated to carding.
6. Formation of sliver: The primary result of carding is sliver. Here, a sliver is created to deposit the fiber material for subsequent use. Transport from the blow room to the draw frame process is also done.

Carding Wool-Making Tools

Carding wool-making tools are described below-

• Cylinder and Licke-in: A flat belt driving cylinder and licker-in have a very straightforward and straightforward structure. The motor’s driving cylinder is stable and smooth.
• Doffer: An inverter and synchronous belt both power the offer. Stepless speed variations are managed by the synchronous belt.
• Cross Apron: Cross apron is used for easy operation and sliver guiding.
• Feed Roller: An electronic frequency converter drives the feed roller. The electronic converter allows for step-less speed variation and is managed by the computer so that it synchronizes with the buffer.
• Pressure Mechanism: The machine’s pressure mechanism delivers measurements and pressure that are consistent in both amount and quality.
• Multi-suction point: Multi-suction of the device is pointed on card
• Flats: To boost web quality, the flats increase carding activities. Brushing and cleaning rollers take the place of the flat stripping comb for this task.
• Electric control system: The electronic control cabinet of card control the doffer’s and feed motor’s speed for making a step-less variable speed and runs it at the rate, with a smooth speed up and down, that is why carding machine runs steadily and reliably for making carding wool

Functions of Carding

Carding fulfills a series of precise objectives, serving:

• to open the blend fibers fully and definitively
• to arrange (as far as their length allows) the fibers parallel with one another
• to remove impurities
• to blend the raw material further
• to reduce the blend to a web of fibers and to divide it up into rovings of the required count, suitable for feeding to the spinning machines.

All spinning cycles depend on cards, but the woolen spinning cycle is where it shines the brightest. Carding serves a variety of functions in this cycle that are all crucial to achieving the level of product quality demanded.

In essence, untangling fiber tangles and sweeping the material over the card allows for the removal of all types of impurities. The cylinders’ surfaces, which are covered in spikes and rotate around parallel axes, are responsible for achieving this.

The apparatus also performs a delicate yet essential additional task: it must ensure the precision and uniformity of the web count, which will then translate into the roving count. In fact, the woolen spinning cycle’s final spinning machines can only produce a very low draft, so there is currently little chance of intervening to change the yarn count.

The carding room equipment thus completes the same tasks that were already completed in the preparation stage, this time more thoroughly, and supplies the divider with rovings of the appropriate count.
