Abstract
CHEMISTS are well aware that wool is readily attacked by alkaline reagents. These disrupt the disulphide groups of the cystine contained in the polypeptide chains, thus weakening the fibre structure. The woollen manufacturer also recognizes that wool is susceptible to attack by alkali, as the term ‘alkali damage’ indicates. This damage frequently results from inefficient scouring which afterwards causes the wool to dye unevenly.
