The woolen and
worsted process both require that the wool (and other similar animal fibres,
cashmere,
camel, etc.) be 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 fiber processing and yarn formation, not in the cloth or finished garment. A woven woolen fabric is one which is subjected to fabric
finishing 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 fibers 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 fibres and the use of a focused 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 more expensive and is seldom used for knitwear. ==Handspinning woolen yarn==
