Comparative Economics of Air-Jet Versus Ring Spinning
topic
Air-jet spinning economic comparison with ring spinning at equivalent yarn count shows 5 to 8 times higher production speed per position offset by higher machine investment cost, higher compressed air energy cost, and raw material requirement for longer staple fibre, with total cost per kilogram advantage of air-jet versus ring spinning dependent on labour cost level, energy cost, and yarn count with crossover typically at Ne 30 to 40.
Role
Guides investment decisions between air-jet and ring spinning technology by quantifying the economic conditions under which each system provides lower cost per kilogram yarn production, enabling mills to identify the yarn count range and production volume where air-jet spinning capital investment is justified by operating cost savings relative to equivalent ring spinning capacity.
