After dyeing the lessened water soluble method of the dyes need to be converted in to the initial drinking water insoluble variety by oxidation. The frequently employed oxidizing agents are-
Dye transfer does not come about at temperatures down below 39°C simply because fibre pores continue being insufficiently open up and dye molecules lack the kinetic energy for successful diffusion in the fibre inside.
Material need to not to expose to air in the course of dyeing to forestall precipitation & oxidation. This may lead to uneven dyeing.
The anionic dye part (R–SO₃⁻) is the only real coloured species; the sodium cation plays no role in the coloration process.
The fixation mechanism includes ionic bonds concerning sulphonic acid groups and protonated amino groups, supplemented by hydrogen bonding and van der Waals forces.
Group A contains acid dyes that demonstrate good affinity in weakly acidic to neutral liquor (pH five–six.5), combined with exceptional migration and levelling Attributes. These dyes are chosen for pale to medium depth shades on nylon wherever maximum levelness is the key necessity.
The dyeing of sulphur dyes needs certain conditions to be certain optimum color growth, fastness properties, and uniform dye uptake. Under is an in depth information to the dyeing technique for sulphur dyes, covering the dyeing system, key parameters, and aftertreatment methods.
Even though acid dyes dominate high-stop textile dyeing due to their fastness and flexibility, essential dyes find applications in industrial domains the place brightness and value-effectiveness are priorities. Knowledge these variations guarantees ideal results for various dyeing assignments.

Silk incorporates a measurable affinity for acid dyes but typically Acid Dyes provides colors which might be less clean-rapidly than equal shades on wool. Silk is dyed at reduced Acid Dyes temperatures than wool: initial dyeing starts at 40°C and the maximum temperature is limited to eighty five°C to circumvent fibre degradation.
If this method is observed to generally be in efficient then the uneven dyed content may very well be handled with a solution of the NaOCl or bleaching powder (two-three gm/Litre of available chlorine).
Group B dyes are selected when deep shades are required and levelness is often attained via controlled dyeing parameters rather then extended migration time.
