Frequently asked questions
Which spinning system is best for my yarn?
Ring for premium quality, rotor for cost-efficient coarse counts, air-jet for high-volume production, compact for premium feel. Match the system to the fiber, count, and end-use.
What is the difference between ring and rotor spinning?
Ring uses a traveler on a ring to insert twist - slower but produces finer, stronger yarn. Rotor uses a rotating cup - faster but coarser, more hair, lower strength. The choice depends on end-use and cost.
What is the twist multiplier (TM) and why does it matter?
TM = TPM / sqrt(Ne). It normalizes twist to yarn count. TM 3.5-4.0 is soft knitting, 4.0-4.5 is general weaving, 4.5-5.5 is hard-twist crepe, 5-6 is sewing thread, 7-9 is crepe yarn.
What is compact spinning?
A modification of ring spinning that adds a suction zone before twist insertion, condensing the fiber strand. Reduces hairiness 30-50%, increases strength 5-15%, costs 5-10% more than conventional ring.
How fast does a modern spinning frame produce?
Ring: 1,000-3,000 rpm, 25-35 g/spindle-hour for cotton. Rotor: 5,000+ rpm, 200-400 kg/frame-hour. Air-jet: 800-1500 ppm. A typical 50,000-spindle mill produces 30-50 tons/day.
