The worsted spinning process is the most elaborate of the processes included here. It requires a relatively fine material, which must be done precisely in order to obtain a particularly smooth, round yarn that is very finely spun. For this purpose: the finer the desired yarn count, the finer the fibre material used needs to be.
The processing is similar to that of woolen yarn. In the combing, the fibre material is separated into single fibres on the worsted carding machine and at the same time the largest impurities like bur, pieces of straw or wood are removed. The fibres are also already oriented lengthwise and combined into a sliver. This is combed out on the combing machine, i.e. short fibre material as well as other impurities of plant origin are removed and the fibres are parallelised.
In the spinning preparation different tops are combined into a spinning batch. Different slivers pass through a drawing unit together, in which optimal blending of the fibres takes place. According to the desired yarn count, this process is repeated several times until the rove is finished. On the ring spinning frame, this is turned into worsted thread.
