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 to Lopi style yarns, or when making a thrummed item. Regular roving can also be used in thrummed knitting.
Doubling of yarn where two or more stands or ends of yarn are twisted together. There are many purposes where doubled yarn is used. Sometimes thread is doubled to make warp, and it is invariably used for the manufacture of knitting yarn, crochet yarn and sewing yarn. All these yarns must be smooth and free from knots.
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 lubricants are added.
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.
There is no roving stage or re-packaging on an auto-coner. This system is much less labour-intensive and faster than ring spinning with rotor speeds up to 140,000 rpm. The Rotor design is the key to the operation of the open-ended spinners. Each type of fibre may require a different rotor design for optimal product quality and processing speed.
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 ...
Most handspinners make a blend of a woolen and worsted yarn, using techniques from both categories, and thus ending up with a mix. The first step to spin a true woolen yarn, however, is to card the fiber into a rolag using handcarders. The rolag is spun without much stretching of the fibers from the cylindrical configuration.
