What does carding do to fibres?

Carding is a mechanical process that is used to prepare fibers for spinning into yarn. The process involves passing fibers through a series of carding machines that use a series of metal teeth or wires to separate and align the fibers.
The carding process has several effects on the fibers, including:

Cleaning: The carding machines remove any foreign matter, such as dirt, dust, or vegetable matter, from the fibers.

Opening: The carding machines separate the fibers and open them up, making them easier to spin into yarn.

Straightening: The carding machines align the fibers in a parallel orientation, which helps to produce a smooth and even yarn.

Blending: The carding machines can be used to blend different types of fibers or different colors of fibers, which can create interesting visual effects in the final yarn.

The end result of the carding process is a web or sliver of loosely aligned fibers that is ready to be spun into yarn. Carding is an essential step in the textile manufacturing process, as it helps to produce yarns that are strong, uniform, and consistent in quality.
