Composite textile yarns, and method of and apparatus for their production.

摘要

A method of producing the equivalent of a two-fold twisted textile yarn with a saving in machinery involves the step, whist a roving (7) of untwisted or slightly-twisted staple fibres is being drafted in a drafting zone, of introducing a previously prepared yarn, (10) of the same or different fibre content, alongside the roving (7) towards the end of the drafting zone, and twisting the primary and secondary yarns together as they emerge from the drafting zone.
