PRODUCTION OF DYED AND SHRINKKPROOF TREATED WOOL

摘要

The aftertreatment of dyed feltproofed keratin-containing fibre material with a reaction product of urea, thiourea, guanidine, dicyandiamide or melamine with formaldehyde and ammonium chloride results in fastness properties, in particular wash and perspiration fastness properties, which exceed those of the non-aftertreated material, in particular in the case of dyeings with metal complex dyes.
