Nonconventional Carded Woolen Spinning

Web divider and rubber draw frames run at relatively low speeds and limit the card in its production capacity. This is of particular importance with fine yarns, as the roving accordingly has to be fine as well. To achieve a low web weight, the throughput of the card has to be reduced. 

With the nonconventional woolen spinning method, which was developed at the Institut fiir Textiltechnik at the RWTH Aachen, Germany, within a research project of the European Union, the slivers are produced on a novel compact card with only one tambour. They have a titer of about 4 ktex. Without additional roving formation, they can be spun directly into a yarn on a nonconventional woolen ring spinning frame or a modified OE-rotor spinning machine. 

Recycled libers can be processed very well with the woolen spinning method. Therefore, research work in woolen spinning is of particular importance.
