Dyeing involves a chemical interaction between colourants and fibres that is influenced by fibre composition, dye class, temperature, pH, and time. Research across textile engineering journals consistently highlights these variables as the primary drivers of colour depth and fastness, establishing a baseline for any technique evaluation.
Beyond the chemistry, external signals such as batch consistency, equipment calibration, and post‑treatment processes shape the final appearance. Peer‑reviewed studies report that even minor deviations in agitation speed or rinse duration can produce measurable colour shift, underscoring the need to consider operational details alongside raw material data.
