How is carding done ?

arding is a process in textile production that involves separating, cleaning, and aligning fibers in preparation for spinning. The process is performed using a machine called a carding machine, which has a series of metal drums and rollers covered with wire teeth.
Here’s how carding works:
The fibers, which may be in the form of loose fleece, sliver, or roving, are fed into the carding machine.
The first drum or roller separates any tangles or clumps of fibers.
The next roller or drum brushes the fibers to remove dirt and other impurities.
The fibers then pass through a series of carding drums or rollers, each of which has a series of wire teeth that further separate and align the fibers.
The final product of carding is a web of aligned fibers, which is then further processed into a roving or sliver that can be used for spinning into yarn.
Carding is a critical step in textile production because it determines the quality and consistency of the final product. Poor carding can result in weak or inconsistent yarn, while good carding produces strong and uniform yarn that is suitable for a variety of uses.
