Ring Spun Yarn Properties and Quality

Ring yarn characteristics: three-dimensional helical fibre arrangement with fibres twisted around yarn core (outer fibres more twisted than inner creating strength gradient), parallel fibre orientation in core providing tensile strength, surface fibres providing cohesion and handle. Quality parameters: tenacity 12-20 cN/tex (cotton 18 Ne: 16-18 cN/tex, polyester 30 Ne: 18-20 cN/tex, combed better than carded by 10-15%), elongation 4-8%, Uster evenness CV% 8-12% (combed 6-10%), imperfections (thin places -50%: <15/km, thick places +50%: <30/km, neps +200%: <50/km for quality yarn), and hairiness index 4-8 (compact 3-5).
