Grey and white wool roving. 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 combed fiber can then be drafted to form a sliver or roving (if the fibers are twisted slightly after drafting, it is called a roving—if not, it is a sliver), or spun directly. The short draw technique can be done from carded rolags, as well, but this does not produce a strictly worsted yarn. Yarns spun from a rolag will not have all the ...
A sliver (/ ˈ s l aɪ v ər /) 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]
A pencil roving is a roving thinned to the width of a pencil. It can be used for knitting without any spinning, or for apprentices. Combing is another method to align the fibres parallel to the yarn, and thus is good for spinning a worsted yarn, whereas the rolag from handcards produces a woolen yarn.
Spinning is a twisting technique to form yarn from fibers.The fiber intended is drawn out, twisted, and wound onto a bobbin.A few popular fibers that are spun into yarn other than cotton, which is the most popular, are viscose (the most common form of rayon), animal fibers such as wool, and synthetic polyester.

A tightly spun wool yarn made from fibre with a long staple length in it is called worsted. It is hand spun from combed top, and the fibres all lie in the same direction as the yarn. A woollen yarn, in contrast, is hand spun from a rolag or other carded fibre (roving, batts), where the fibres are not as strictly aligned to the yarn created. The ...
A ring spinning machine in the 1920s. Ring spinning is a spindle-based method of spinning fibres, such as cotton, flax or wool, to make a yarn.The ring frame developed from the throstle frame, which in its turn was a descendant of Arkwright's water frame.
Unlike the Navajo spindle, however, the spun yarn is wrapped around the lower end of the spindle. The roving is prepped first by drafting it before the wool is spun into yarn. The separation between the drafting and spinning creates a softer yarn. Since it is a supported spindle, the yarn is less strained, which also makes the yarn soft. [19]
