Woolen or woollen is a type of yarn
Yarn
Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery and ropemaking. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or...

Carding
Carding is a mechanical process that breaks up locks and unorganised clumps of fibre and then aligns the individual fibres so that they are more or less parallel with each other. The word is derived from the Latin carduus meaning teasel, as dried vegetable teasels were first used to comb the raw wool...

Wool is the textile fiber obtained from sheep and certain other animals, including cashmere from goats, mohair from goats, qiviut from muskoxen, vicuña, alpaca, camel from animals in the camel family, and angora from rabbits....

Knitting
Knitting is a method by which thread or yarn may be turned into cloth or other fine crafts. Knitted fabric consists of consecutive rows of loops, called stitches. As each row progresses, a new loop is pulled through an existing loop. The active stitches are held on a needle until another loop can...

Commercial manufacture

The woolen and worsted process both require that the wool (and other similar animal fibres, cashmere, camel, etc.) are cleaned before mechanical processing. Woolen and worsted nomenclatures apply only to the textile processing of animal fibres, but it has become common to include fibre blends under these terms.

The resultant fabrics will be classified as being either woolen or worsted, but this designation is assigned during fibre processing and yarn formation, not in the cloth or finished garment.

 techniques designed to add a directional pile - in that the end consumer can 'stroke' the garment in a single direction (shoulder to cuff etc), such as a casual jacket. This feels like the fibres are directionally arranged.

Woolen yarn formation is also very common for knitwear, where the resultant garment has some bulk and the requirement for visual aesthetics (of fibre alignment) is minimal.

The worsted processing route is more complex and requires the removal of short fibers and the use of a focussed mechanical process to make the individual fibres parallel to each other. The yarn formation process is significantly more comprehensive and results in a very sleek yarn which will offer a clean looking woven fabric, such as for suitings. The worsted process is significantly more expensive and is seldom used for knitwear.

.

The rolag is spun without much stretching of the fibers from the cylindrical configuration. This is done by allowing twist into a short section of the rolag, and then pulling back, without letting the rolag change position in your hands, until the yarn is the desired thickness. The twist will concentrate in the thinnest part of the roving, thus when the yarn is pulled, the thicker sections with less twist will tend to thin out. Once the yarn is the desired thickness, enough twist is added to make the yarn strong. Then the yarn is wound onto the bobbin, and the process starts again.
