A zip selected before a dyeing stage must be considered in relation to that stage. A convenient colour description cannot replace the component's actual process suitability.
Coats discusses zip selection and processing for ready-for-dyeing applications. Coats — Properly Dying Zips (RFD).
Identify the supplied construction
For a post-dyed textile item, obtain the actual component specification and relevant supplier guidance. Do not assume that every part of a zip responds identically to the proposed process.
Evaluate the finished item
Review colour, condition and the applicable operation requirements after the relevant process. Preserve the evaluated combination and any restrictions. A material selected for one dyeing route should not become an unrestricted substitute across other processes or products.
