This is the W page of the Production and Sourcing category index, which files the category's role descriptions alphabetically by job title.

Washroom Operator — Runs garment wet processing on industrial washers, extractors and tumble dryers: stonewash and enzyme washes, garment dyeing support, softening and final washes, all to written recipes of time, temperature, water and chemicals, with every batch checked for shade, hand-feel and shrinkage against the approved standard.
It is the only W in the category, and one of its most tactile trades: a finishing skill learned at the machine, where a few minutes or a few degrees decide whether five hundred garments match the standard or miss it.
Production and Sourcing covers the making side of fashion: developing and engineering styles, pattern cutting by hand and computer, colour work in laboratories and dye houses, factory management, quality control and sourcing. Its seventy-eight descriptions sit across sixteen letters — A, C, D, E, F, G, I, L, M, O, P, Q, S, T, V and W in the bar above — fullest at P, with fifteen roles in the production-office family.
One: Washroom Operator, the garment washing and wet-processing role in clothing finishing. It is linked above with a full description of duties, skills, training and career path.
The industrial laundry inside garment finishing where clothing is washed to its final state — stonewashed denim, garment-dyed pieces, softened and pre-shrunk garments — following recipes rather than simply being cleaned.
