Abstract
Improvements in conventional ring spinning processes of the type wherein a strand of staple fibers if drafted, twisted and collected on a ring spinning frame are obtained by the added step of subjecting the strand to the twisting action of a pneumatic false twister between the drafting and collecting steps. The added step improves performance and/or permits the process to be operated at higher front roll delivery speeds for any given spindle speed without sacrificing performance. The higher delivery speeds results in improvements in the productivity of the process and the apparent value of staple yarn produced thereby.
