The application of the Hercossett-Anionic-Surfactant process to impart Shrink-Resitance to wool

The possibility of a new pre-treatment-resin shrink-resist process, based on the application of a dispersion of Hercosett resin and an anionic surfactant to methylamine-pre-treated wool samples, was proposed at the Fifth International Wool Textile Research Conference1. Further studies on this topic, as well as some attempts to develop new alternative pretreatments, such as oxidation with hydrogen peroxide or reduction with thioglycolic acid, have opened up new possibilities for the process and are described in this lette
