What is the process of carding machine?
A carding machine is a textile manufacturing machine used to create carded fiber or carded yarn, which is the process of separating, cleaning, and aligning fibers into a thin web or sliver. The carding process involves the following steps:
1)Feeding: The raw material, such as cotton, wool, or synthetic fibers, is fed into the carding machine using a feed roller.
2)Opening: The fibers are opened up and loosened by a series of rotating drums with wire teeth called the opener rollers.
3)Cleaning: The fibers are then cleaned of any impurities, such as dirt, seeds, or other debris, by a series of cleaning rollers.
4)Carding: The carding process involves a set of main rollers that have fine wire teeth, which comb and align the fibers into a thin web or sliver. The sliver is then wound onto a large spool or canister.
5)Drawing: The sliver is then passed through a series of drawing rollers, which further straighten and refine the fiber alignment.
6)Roving: The drawn sliver is then stretched and twisted by a roving machine, which creates a continuous strand of yarn that can be used for spinning or weaving.
