The article presents a formula for producing deviation rate filter (DRF) spinning techniques using polywool (P/W) yarns. DRF yarns are reportedly produced by drafting two adjacent or the same drafting systems together and twisting these strands on the same spindle. It is said that strand spacing is important because this can affect yarn quality and spinning performance. The mechanism of twist propagation and distribution is described. Focus is also given on inter-stand spacing at the front roller nip.
