What this course is
A free, self-paced course on garment wet processing and finishing: wash foundations and garment dyeing, effluent and chemical safety, denim wet processing, enzyme, stone and bleach effects, dry-process finishing, shade control and reproducibility, recipe and process control, and post-wash defects with corrective action. Three modules, each ending with a five-question quiz.
Who it is for
- • Wash-plant operators, supervisors and recipe developers
- • Denim product developers and technicians
- • Quality staff inspecting washed and finished garments
- • Merchandisers approving wash standards and shade bands
What you will be able to do
- • Read a wash recipe and say which variable changes the effect and which changes the shade
- • Judge an enzyme, stone or bleach effect for strength loss as well as appearance
- • Explain why a shade drifts between loads and what to hold constant to stop it
- • Trace a post-wash defect to the process step that made it
- • State the chemical, effluent and worker-safety controls a wash plant must hold
Modules
Module 1 — Garment Wet Processing
Run garment wet processing with the variables understood: load, liquor ratio, time, temperature, chemistry and mechanical action, plus the safety and effluent duties that come with them.
3 subjects · five-question quiz
Module 2 — Effect Development
Develop a denim or casual effect that matches the standard and survives wear: wet effects, enzyme, stone and bleach work, and dry processes in the right order.
3 subjects · five-question quiz
Module 3 — Finishing Process Control
Hold the process: reproduce shade load after load, control the recipe in production, and close post-wash defects at their source.
