How Much Thiourea Dioxide Would I Need per Tonne of Fabric?

A simple calculation is: Thiourea Dioxide kg/tonne = dosage g/L × liquor ratio L/kg ÷ 1,000.

For example: dosage 1.5 g/L and liquor ratio 10:1 → 1.5 × 10 ÷ 1,000 = 0.015 kg/kg fabric, or 15 kg Thiourea Dioxide per tonne of fabric.

At a 5:1 liquor ratio: 1.5 × 5 = 7.5 kg/tonne.

This demonstrates why liquor ratio has a major effect on chemical consumption.
