Yarn Oiling and Lubrication at Winding
topic
Yarn lubrication application at winding uses rotary oil roller, wick applicator, or metered spray systems to apply mineral oil, synthetic lubricant, or wax emulsion at 0.2 to 1.5 percent on yarn weight for filament yarns requiring lubrication for warp sheet cohesion and heddle friction reduction, with oil add-on uniformity across all winding positions being essential for consistent warp yarn friction characteristics that determine heddle wear rate and warp break rate during weaving.
Role
Reduces yarn-to-heddle and yarn-to-reed friction during weaving by applying lubricant at the winding stage that distributes uniformly along the yarn surface through subsequent handling, with lubrication being particularly important for textured filament warps where inter-filament friction without lubrication causes fibre separation at heddle contact that generates warp breaks and increases loom stop rate progressively as the lubricant is consumed during weaving.
