Abstract
A method for continuously producing a twisted yarn with minimal curling tendency includes the steps of spinning a yarn and directly thereafter, within a time period of less than one second, twisting the yarn. The yarn tension at the end of the spinning step can be adjusted to be essentially the same as the yarn tension at the end of the twisting step, or, in the alternative, the yarn tension at the end of the twisting step is greater than 70% of the yarn tension at the end of the spinning step.
