1 – 4g/l Polycol-RCA
1 – 2g/l Caustic Soda Flakes.
at 70°C 80°C for 15 – 20 minutes.
Hot wash, rinse cold & neutralise with dilute acetic acid.
In the case of dyeing where exhausion is almost complete i.e. no residual dyestuff in the bath, reduction clearing can be carried out in the same bath by addition of POLYCOL-RCA and caustic soda flakes.
Reduction clearing of disperse prints.
On a continuous washing machine.
1st bath1g/l POLYCOL-RCA
2 – 4g/l Hydrosulphite (to enhance reducing action at low temperatures)
2nd bath2 – 3g/l Caustic Soda Flakes at 25°C 30°C
