Sliver (textiles)

A sliver (/ˈslaɪvər/) is a long bundle of fibre that is generally used to spin yarn. A sliver is created by carding or combing the fibre, which is then drawn into long strips where the fibre is parallel.[1] When sliver is drawn further and given a slight twist, it becomes roving.[2][3]

Worsted textiles differ from woolen textiles in that, after carding, they are subjected to gilling, a process to make sure the sliver has a more uniform linear weight, and add lubricants.[4][5][6]

The latter is achieved by passing the wool at least once through a special gilling machine which has an auto-levelling device, which continuously detects the linear weight of the slivers being fed into the machine, and speeds up or slows down the machine accordingly.
