The value of the urea‐bisulphite solubility test as a guide in determining the optimum conditions for dyeing loose wool has been demonstrated. Using this test as a criterion, it was concluded that dyeing should be carried out at a temperature not exceeding 93C for not more than 60 min, the final dyebath pH not to exceed 55. When these conditions were employed, e.g. in a solvent‐assisted dyeing process, marked improvements were observed in the carding and spinning properties of the dyed wool and there was an increase of 25% or more in the abrasion resistance of carpets made from the loose wool.
