Wool fabrics undergo setting during dyeing. The degree of set can be controlled by careful selection of dyebath conditions and also by the addition to the dyebath of chemicals termed anti‐setting agents. The anti‐setting effect of sodium thiocyanate has been evaluated according to its concentration in the dyebath and the dyebath pH. The fabric crease‐angle method was adopted to estimate the degree of anti‐setting. In the case of wool fabric boiled in the presence of sodium thiocyanate, good anti‐setting effects resulted from the pH 3 and pH 5 treatment baths. Chemical changes in the wool were detected using FTIR analysis.
