How to Use This Calculator
  1. Enter Fabric weight (kg), Liquor ratio (X:1), and Dye concentration (% OWF).
  2. Set Stock solution strength (g/L) and Auxiliary dosage (% OWF).
  3. Review the Total bath volume (L) result.
  4. Use Water to add (L) and Dye needed (g) to inform your decision.

How the result changes with Fabric weight (kg)

3503,500
6506,500
9009,000

What each input means

Fabric weight (kg)
Dry weight of the fabric or yarn to be dyed, in kilograms.
Liquor ratio (X:1)
Ratio of bath volume to fabric weight. E.g., 10 means 10 liters per kg of fabric.
Dye concentration (% OWF)
Dye amount as percentage on weight of fiber. Light shades: 0.5-1%, medium: 1-3%, dark: 3-6%.
Stock solution strength (g/L)
Concentration of your dye stock solution in grams per liter.
Auxiliary dosage (% OWF)
Salt, soda ash, or acid dosage as percentage on weight of fiber.

What each result means

Total bath volume (L)
Total dye bath volume needed in liters.
Water to add (L)
Water needed (bath volume minus fabric displacement).
Dye needed (g)
Weight of dye powder or paste required.
Stock solution to add (mL)
Volume of dye stock solution to measure out.
Auxiliary chemical (g)
Weight of auxiliary chemicals (salt, soda ash, acid).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Fabric weight (kg) = 1, Liquor ratio (X:1) = 10, Dye concentration (% OWF) = 2, Stock solution strength (g/L) = 10 = 5 input(s) provided
  2. Calculate Total bath volume
    Total bath volume = fabricWeightKg * liquorRatio
    10 = 10
  3. Calculate Water to add
    Water to add
    9 = 9
  4. Calculate Dye needed
    Dye needed = fabricWeightG * (dyeConcentrationOwf / 100)
    20 = 20
