Operating Cost Comparison Across Technologies
topic
Shuttleless loom operating cost comparison across technologies accounts for energy consumption including electricity for mechanical drive and compressed air for air-jet, maintenance parts and labour, consumable components including rapier bands and gripper heads, reed replacement, operator labour for multi-loom attendance, and yarn waste from selvedge trimming, with air-jet having the highest energy cost from air compression but lowest mechanical maintenance, rapier having moderate energy cost but higher component cost from gripper head replacement, and projectile having high maintenance cost from wear component intensity.
Role
Enables total cost of ownership comparison that goes beyond capital investment to the ongoing operating costs that determine the fabric production cost over the loom's service life, with operating cost differences between technologies being as significant as capital cost differences in the long-term economics, and with energy cost being particularly important at current electricity prices where the compressed air energy of air-jet weaving can be the dominant operating cost exceeding the loom capital depreciation on an annual basis.
