Siro Spinning and Plying During Spinning
topic
Sirospun technology feeds two roving strands through the ring frame drafting system with defined separation between strands, allowing each strand to develop twist before the two strands combine and ply twist is inserted simultaneously with the spinning twist, producing a two-ply equivalent yarn in a single spinning operation that eliminates the separate twisting or folding stage required in conventional two-ply yarn production.
Role
Enables production of two-ply equivalent yarns with improved evenness, reduced hairiness, and higher abrasion resistance compared to single ring yarn in a single-stage process that eliminates the capital investment, floor space, and operating cost of a separate twisting stage, making two-ply quality yarn production economically attractive for medium-count weaving applications where single-stage production cost is critical.
