1. Exhaust Process :
Sarawhite-PC is suitable from neutral and slightly alkaline baths without or particulary for regenerated cellulosing fibres with addition of electrolyte, preferably in combination with the reduction or alkaline peroxide bleach. It is not suitale in pack systems without forced liquor flow.
2. Continuous Process :
Sarawhite-PC is suitable for Peroxide continuous bleach and wash-whitening process.
STABILITY & FASTNESS PROPERTIES :
|Reduction bleach (hydro sulphite based)
||Change in degree of whiteness
|Wash fastness, 60 deg.C
||ISO 105-C06 C1
|Dry heat fixation, 180 deg.C
