Sample Calculation for Color matching

Example : Apple Green

Use : Stock solution 1.0% each dyes

Weight of sample 10 grams

Liquor ratio 1:100

Recipe : Astrazon Blue A-BG 0.10%

Astrazon Yellow A-8GL 0.50%


19/24

Computations : Blue 0.10%/100% x wt. Sample x stock solutiontherefore 0.001 x 10 gms x 100 ml water/1 gm

blue dye

= 1 ml

Yellow 0.50%/100% x 10 gms x 100 ml water/

1 gm yellow dye

= 5 ml

Total Dyestuffs : 6 ml

Volume : 100 ml 6 ml

= 94 ml (actual volume of water)

NATURAL DYEING(3 Steps)

How to Do the Extraction?

1. Chopped or grind the dye source (ex. Dulaw).

2. Weigh.

3. Compute and measure the volume of water usingliquor ratio 1:30.

1. Boil the chopped/grind dye source in the water.

2. Filter and set aside.
