In short staple spinning, the blow room is the first step in the process of converting raw cotton fibers into yarn. It is a machine room where the cotton bales are opened, cleaned, and blended to create a uniform blend of fibers. The process involves a series of machines that work together to remove impurities like dirt, dust, and other foreign materials, and then break the cotton into smaller tufts or flocks. The final product of the blow room is a homogeneous mass of fibers, ready to be processed into yarn.

Carding
Carding is a process in yarn manufacturing that follows the blow room process. It involves the use of carding machines to further clean and align the fibers, creating a thin web of fibers called a “carded sliver.” The carded sliver is then passed through a series of processes to further refine it and create a more uniform yarn.
There are two main types of carding in yarn manufacturing:
- Flat carding: In this type of carding, the fibers are aligned in a flat manner, with the help of carding machines that use a series of rollers and combs to separate and align the fibers. The fibers are then compressed into a thin web or sliver, which is then used to create yarn.
- Roller carding: In this type of carding, the fibers are aligned in a cylindrical shape, with the help of carding machines that use a series of rollers to separate and align the fibers. The fibers are then compressed into a thin web or sliver, which is then used to create yarn.
Both types of carding help to create a more uniform blend of fibers, remove any remaining impurities, and align the fibers in the same direction to create a more consistent yarn. The choice of which type of carding to use depends on the specific requirements of the yarn being produced.
