Roving Yarn
A roving is a long and narrow bundle of fiber. Rovings are produced during the process of making spun yarn from wool fleece, or other fibres. Their main use is as fibre prepared for spinning, but they may also be used for specialised kinds of knitting or other textile arts.
After carding and combing, the fibres lie roughly parallel in smooth bundles. These are drawn out, by hand or machine, and slightly twisted to form lengths suitable for spinning. These unspun strands of fibre are the rovings. Roving can also mean a roll of these strands, the strands in general or the process of creating them.
