As we know, the Chlorophyllin is responsible for the green colour of plant leaves. The extract green is produced from the leaves of green plant & grass as raw material and acidified, saponified with Copper-based salt for the green colour(Sodium Copper Chlorophyllin). The extract gives olive shade to dark green shade by adjusting the pH and dye concentration. It can provide products with good acid resistance and light resistance. Widely used in fields of frozen drinks, Processed seeds and nuts, confectionery and Dyeing of fibres etc.
(A) Wet the fabric with wetting agent/soapnut(Reetha) or normal wash with water at 50 degree for 20 mins.
(B) Pre Mordant :- Pre-treat the material with alum 12% of fabric weight at 85°C for 60 mins.
(C) Dyeing :- Add the required amount of dye to the dye bath. PH of dye bath needs to be maintained at pH 7. If it is higher than pH, 7 add vinegar, if below pH 7, use lime or soda ash. Stir well to dissolve the dye. Add fabric to the dye bath and maintain at 95°C for 60-80 mins. We check all our natural dyes at 5% of fabric weight; you can amend the percentage as per lighter or darker shade required.
(D) Post Treatment :- Conduct soaping of the dyed material with non-ionic detergent (0.5gpl) or ezee soap at 50°C for 35 mins.
(E) Then conduct cold wash of the material at 50°C for 20 min or more time.
