Textile Dyeing Water Consumption Calculator

Each bath uses fabric weight × liquor ratio litres of water. Add the dye bath to every pre-treatment, rinse, soaping and finishing bath to get water per batch and per kilogram.

How to use this calculator

  1. Enter or choose fabric per batch.
  2. Enter or choose dye-bath liquor ratio (1 : L).
  3. Enter or choose other baths per batch.
  4. Enter or choose liquor ratio of other baths (1 : L).
  5. Enter or choose batches per day.
  6. The water per batch updates as you type. Use Copy result or Share to keep it.

Method

Water per batch = Fabric kg × (Dye LR + Other baths × Other LR); Per day (m³) = Water per batch × Batches ÷ 1,000

LR
liquor ratio: litres of water per kg of fabric
Other baths
every bath apart from the dye bath

Worked example

  1. Dye bath = 500 × 8 = 4,000 L.
  2. Other baths = 500 × 6 × 10 = 30,000 L.
  3. Per batch = 34,000 L, or 68 L per kg.
  4. Four batches = 136 m³, costing 136 × 0.50 = 68 a day.

A 500 kg batch with a 1:8 dye bath and six 1:10 baths uses 34,000 litres, 68 litres per kilogram.

What the result means

Rinse and wash baths usually use more water than the dye bath itself, so lower-liquor-ratio machines and fewer or counter-current rinses save the most water.

Assumptions and limits

  • Each bath is filled once to the stated liquor ratio.
  • The liquor ratio is based on dry fabric weight.
  • Overflow rinsing, machine cleaning, steam and cooling water are not included.

Questions

What does a liquor ratio of 1:8 mean?

8 litres of water for every 1 kg of dry fabric in the bath.

Why do overflow rinses use more water?

Water runs continuously through the machine, so the volume depends on flow rate and time rather than the bath ratio.
