A study has been made of the effect of abrasion of wool on the characteristic properties of individual acid dyes on wool fibres. When abrasion takes place before dyeing, the abraded areas dye initially more heavily than the unabraded areas. When abrasion occurs after dyeing, the abraded areas appear to be less heavily dyed, owing to an optical effect caused by fibrillation of the fibres. Rubbing of wool against wool produces an effect identical with that obtained on abrasion by glass‐paper or other abrasives. The time required to produce level dyeings on abraded wool varies widely from dye to dye, and the degree of sul‐phonation of the dye has an important effect. Certain cationic auxiliary agents reduce the time required to produce level dyeings. Apparently, abrasion increases the hydrophilic nature of the fibre surface.
