摘要：
A method for producing staple fibre yarn comprises positively drafting sliver to produce a staple fibre sliverlet, then twisting the staple fibre sliverlet by means of a twisting part to produce yarn which is then supplied to a bobbin and wound on the bobbin. The sliverlet is subjected to negative drafting after the positive drafting and is simultaneously twisted in the negative drafting zone in a certain direction.
