Abstract
An account is given of an investigation in which thirteen batches of wool tops treated by the chlorine–Hercosett shrinkproofing method were obtained from plant running under industrial conditions. Six lots were completely shrinkproofed. Fabrics made from the others did shrink under certain conditions; the shrinkage rates were then highly dependent on several factors: the yarn linear density, the cover factor, the severity of the wash, and the presence of processing oils. Photographs show that a small proportion of the fibres are still able to migrate through the structure.
