Productivity and Fabric Output Comparison
topic
Fabric output comparison between shuttleless technologies uses specific insertion rate in metres of weft per minute as the primary productivity metric, calculated as picks per minute multiplied by fabric width, with air-jet leading at 2000 to 4000 metres per minute for fine smooth yarn fabrics, rapier achieving 600 to 1500 metres per minute across a wide fabric and yarn range, water-jet at 800 to 1500 metres per minute for synthetic filament, and projectile at 400 to 800 metres per minute for heavy fabrics, enabling direct output comparison on a common metric.
Role
Quantifies the production throughput differences between technologies in a format that enables direct comparison of the fabric output per machine investment, with specific insertion rate being the most meaningful productivity metric for comparing different width and speed combinations that picks per minute alone does not capture, and with the significant speed advantage of air-jet for its applicable yarn range being the primary justification for its dominant position in high-volume commodity fine fabric production.
