COMBED COTTON Combed cotton is made by treating the cotton fibres before they are spun into yarn. The harvested cotton is passed over fine brushes (the 'combs') to remove impurities and short fibres. About 15% of the volume is removed in this process, leaving only long, straight fibres. The slivers of combed cotton are then spun into thread. Generally, combed cotton is more expensive than conventional carded cotton. RING-SPUN COTTON The yarn created for ring-spun cotton is spun in a way that produces stronger and longer threads, as it is continuously twisted and thinned to create an extrafine string of fibres. During this process, the threads are compacted to produce a very strong and durable material. The more times the fibre has been spun and twisted, the softer it feels. Open-end yarn that is not ring-spun often results in fabric with a rough texture. 317
