Ammonium Sulphate



Ammonium sulphate is a slow release acid that gradually acidifies the dyebath with the application of heat.

We recommend this product for use in acid dyeing on protein (animal) fibres where an even result is required. It is particularly useful with superwash yarns where a slower strike is required to achieve even colours.

Combine with Glauber’s salts for level (even) colours.
