Meeting of the West Riding Region, held at the University of Bradford on 8 October 1970, Mr J. Furniss in the chair The continuous dyeing of wool, polyester and acrylic tops by pad–steam methods is discussed. For wool, evidence is given to indicate the specific action of pad‐liquor additives and to show that successful results can be obtained by both one‐phase and two‐phase methods. In the pad–steam dyeing of polyester top, the problems encountered in the selection of compatible dyes can be solved by a study of the effect of time and temperature on exhaustion. The problems associated with the production of heavy depths on acrylic fibre tow are considered in detail. Under practical conditions, the saturation obtained in pad–steam dyeing is lower than that in conventional dyeing methods.
