SIRO SPUN YARN

The twist in the component strands induces additional fiber trappings.

The process

With the “SIRO SPUN” process, a special spin-twisted yarn can be produced directly on the ring-spinning machine. In this process, two roving are led in parallel through the drafting system, separated by two specially developed condensers, and drafted separately.

The twist is introduced as for a normal single yarn by means of ring and traveller. The roving strands, which are drafted parallel, are combined after passing the front rollers at the exit from the drafting system, with some twist being produced in the individual strands right up to the nip point. Once past the front roller of the drafting system, the two strands are combined producing a twofold-like yarn.  The yarn has uni-directional twist like a singles yarn but the fibers are bound sufficiently for the yarn to survive weaving/Knitting.

The process Technology of SIRO spun yarn imparts better surface abrasion resistance and pilling resistance in comparison to Normal & compact  yarn.
