DYEING LAB CALCULATION

DYEING LAB CALCULATION

·         0.5 % Stock Solution – Required dye =

Example- For 0.1% Shade-

      Required dye (ml) from 0.5% stock solution =  

                                                                               = 0.5 ml from 0.5% dye solution.

Fabric weight = 2.5 grams (M: L = 1:20)

Necessary ml pipette = 

40 gpl salt for Bulk – 50 (M : L) = 50 Total Liquor Solution of Lab 100 = 10 % Salt solution 1cc ≅ 100 mg

                                   Example, 40 gpl for bulk salt dozing the calculation would be –

                                  =

                                  = 20 ml.

SOLOPHENYLE DIRECT DYE

Sl. No.	Shade Percentage -SP%	Water (ml)	Dye (ml)	Salt (ml)	Salt- gpl
1	0.1 ml	45 ml	0.5 ml	5 ml	10 gpl
2	0.5 ml	37.5 ml	2.5 ml	10 ml	20 gpl
3	1.0 ml	30 ml	5 ml	15 ml	30 gpl
