Peroxide Killers

The residual peroxide present in the fiber will oxidize the reactive dyes, a chromophore that contains the metal ions and leads to tonal variation and sometimes uneven dyeing. In some cases, the chromophore itself is getting destroyed into a colorless product and lead to pale or white patchy dyeing. Hence the removal of residual peroxide is very much essential before starting a good dyeing operation. A chemical that kills the residual peroxide in the fibre is termed as a peroxide killer.
