Woolen Yarn


Woolen or woollen is a type of yarn made from carded wool. Woolen yarn is soft, light, stretchy, and full of air. It is thus a good insulator, and makes a good knitting yarn. Woolen yarn is in contrast to worsted yarn, in which the fibres are combed to lie parallel rather than carded, producing a hard, strong yarn.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.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 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. We are one of the biggest supplier of the woolen yarn.
