Abstract

Scale-up of a textile spin finish is successful only when laboratory performance is reproduced across raw-material batches and operating conditions while the final textile remains conforming. A hierarchical acceptance framework is proposed that separates raw-material batch, independent formulation preparation, finish add-on, and relative-humidity effects. The first contribution is a robustness criterion based on independent preparations and measurement uncertainty rather than on the number of yarn segments. The second contribution is a cost-of-conformance boundary that combines actual finish consumption with non-finish operating costs and is applied only after the required quality limits are met. This changes the economic comparison from nominal formulation price to the cost of producing one tonne of conforming textile.
