Feda-SH (MOD) is a a highly effective alkali buffer for the replacement of soda ash and sodium silicate in Reactive dyeing. It requires 1/4th dosage of the soda ash during dyeing. It posses good solubility in water therefore does not give powdery deposition in machines or on roller. Due to its lower dosage in dyeing, it reduces TDS, COD, BOD load in the effluent.Feda-SH (MOD) Substitutes Sodium Silicate hence it is highly recommend for the process house which has RO treatment plant. By using Feda-SH (MOD), no white deposit are observed on machine or on mangle or glass parts on washing machine like the Silicate. With use of Feda-SH (MOD) less frequent grinding of roll is required. It can be applied by dosing system at 20% concentration.
Feda-SH (MOD) can be used to get best dyeing result especially when dyeing yarns; fabric by pad batch or exhaust method.
