Aroving is a long and narrow bundle of fiber. Rovings are produced during the process of makingspun yarn fromwool fleece, raw cotton, 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.
Aftercarding, the fibres lie roughly parallel in smooth bundles. These are drawn out, by hand or machine, and slightly twisted to form lengths suitable for threadspinning. These unspun strands of fibre are the rovings. Roving can also mean a roll of these strands, the strands in general (as amass noun), or the process of creating them.
Because it is carded, the fibres are less parallel thanwool top (which is combed) and are not of uniform length. Carded rovings look fluffier than combed top, which looks smooth and has a high lustre. The fibres in combed top tend to be of a fairly uniform length due to the method of preparation. Though drawing it into strips may line the fibres up a bit.[1][2] Roving is not to be confused withsliver as there is twist in roving.
Pencil roving is a type of roving that has been drawn until it is the size of a fat pencil. It can be used by spinners with minimal drafting (withdrawing fibers from a clump). Knitters also use pencil roving, similar toLopi style yarns, or when making athrummed item. Regular roving can also be used in thrummed knitting.
