100—THE USE OF REACTIVE DYES FOR DYEING WOOL AND WOOL UNIONS

Abstract

The effect of dyebath pH on the hydrolysis, rate of reaction and rate of exhaustion of Procion dyes on wool is discussed, and information is presented on the effect of fixation on fastness properties. The relation of these properties to the practical dyeing behaviour of Procion dyes on wool is discussed and optimum dyebath conditions are suggested. The application of Procion dyes to wool from dyebaths containing solvents both by batchwise and continuous dyeing methods is outlined. The use of Procion dyes for the production of fast shades on the cellulosic portions of wool/cellulosic unions are described.
