A roving is a long and narrow bundle of fiber. Rovings are produced during the process of making spun yarn from wool 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.
The machine-carded roving is produced in disc-shaped rolls. This is the original unspun lopi first used for knitting c.1920s. More recently, lightly spun lopi yarn in different thicknesses has become available. Most wool produced in Iceland is processed by Ístex, the Icelandic Textile Company. [1]
