What is Siro Spun?
The yarn has a structure similar to the plied yarn, with less hairiness, which makes the fabric look smooth, feel smooth, soft, elastic, resistant to friction, and breathable. It has become the yarn used for weaving high-grade fabrics.
Sirospun is a spinning method of spinning yarns similar to the yarn structure on the traditional ring spinning machine. Two roving yarns with a certain distance are fed on the spinning machine, and after drafting, the two single yarn spinners are output from the front roller with a small amount of twist on the single yarn spinners due to the transfer of twist. It is then further twisted into a similar yarn, which is wound on the bobbin.
Siro spinning and twisting spinning, known as A, B yarn.
The advantages of Siro spinning
- Yarn breaking strength is high;
- Large elongation at break;；
- Hairness greatly reduced;
- Good wear resistance and pilling resistance;
- Thick and thin yarns are significantly reduced;；
- Reduced flyings in the workshop;；
- Save energy and labor;；
- Less investment in equipment.。
Yarn structure and properties of Siro spinning
Siro spinning yarn structure
- The fibers on the surface of the yarn are arranged neatly and the yarn structure is compact;
- The appearance is smooth, the section shape is close to the circle, has the obvious double helix structure;
- The overall structure is more similar to single yarn, but has the style and advantages close to plied yarns.
Yarn forming properties of Siro spinning
- Yarn breaking strength is high;
- High elongation at break;
- Hair reduction;
- Good resistance and pilling resistance;
- Compared with ordinary ring spinning: sliver, thick knot and nep are slightly improved.
