Worsted, Semi-Worsted and Woollen Yarn – Processes at a Glance

During carding, the fibre material is opened, separated and evenly distributed. At the outlet of the card, a uniform fibre web is formed. The subsequent processing of this fibre web depends on the spinning process.

In worsted yarn production, the fibre web is condensed into a fibre sliver and subsequently fed into the drawing process, where the sliver is further evened and drafted.

In semi-worsted yarn production, mainly longer fibres are processed. The fibre web is also condensed into a fibre sliver and fed into the subsequent drawing processes. During drawing, the fibres are further parallelized and the sliver is evened. In the semi-worsted process, the combing process is omitted.

In woollen yarn production, the fibre web passes through a web divider with a Nitschel unit. The web is divided into narrow fibre strips, which are condensed into rovings. These rovings are then only slightly drafted and spun into the final woollen yarn.
