Dyeing Recipe Calculator

Dye is weighed as a percentage of fabric weight: 10 kg at a 2 % shade needs 200 g of dye in a 100 L bath at 1:10.

Material weight (kg):

Shade (% on weight of fabric):

Liquor ratio 1 :

Salt (g/L):

Soda ash (g/L):

Dye stock solution (g/L), optional:

To give the volume of stock to pipette; 0 to skip.

Dye required =

200 g

Precision

Bath volume = weight × liquor ratio: 100 L
Salt: 6 kg
Soda ash: 2 kg
Dye concentration in the bath: 2 g/L
Stock solution to add: 20000 mL

Step-by-step solution

Dye = weight × shade % = 10000 g × 2 % = 200 g
Bath = 10 kg × 10 = 100 L
Chemicals = g/L × bath volume

Dyeing Recipe Formula

Dye (g) = weight (g) × shade %

bath (L) = weight (kg) × liquor ratio; chemical = g/L × bath

Worked Example

10 kg of cotton dyed at 2 % shade, 1:10 liquor, 60 g/L salt and 20 g/L soda ash:

Dye = weight × shade % = 10000 g × 2 % = 200 g
Bath = 10 kg × 10 = 100 L
Chemicals = g/L × bath volume

Salt: 6 kg · Soda ash: 2 kg · Dye concentration in the bath: 2 g/L · Stock solution to add: 20000 mL

Frequently asked questions

What does 1:10 liquor ratio mean?

10 litres of dye bath for each kilogram of material.

Why are salt and soda given in g/L and dye in % owf?

Dye uptake depends on the amount of fibre, while salt and alkali act through their concentration in the bath.
