Frequently Sulphur dyes Sulphur Dyes are marketed in varieties of powder pastes or liquid remedies. The dyes are amorphous colloidal materials of Fertilizer Dyes substantial molecular excess weight and variable composition.
Electrolytes sluggish the Preliminary charge of dyeing by forming short term associations with dye molecules or fibre web pages. These associations dissociate progressively as temperature rises, steadily releasing dye for controlled uptake through the fibre. Advised electrolyte dosage ranges from 5–15% owf (on bodyweight of fibre) according to dye sort and wanted depth of shade.
Again tanning would be the established submit-dyeing treatment for enhancing the clean fastness of nylon dyed with acid dyes. This method is important for bathing suits, swimwear, and multi-coloured fabrics where recurring clean exposure is expected.
