Quick Summary

In yarn manufacturing, a sliver is a loose, soft strand of textile fibers with a roughly uniform thickness. It is created during the carding process, which separates raw fibers to prepare them for spinning. Carding uses pinned rollers or paddles to align the fibers and remove impurities. After carding, slivers can be combed to remove short fibers and ensure parallel alignment. Multiple slivers can then be combined and drawn to further straighten the fibers and reduce thickness, sometimes with a slight twist added in a process called roving.12
