Abstract
A description is given of the use for dye fixation of high‐temperature steam, i.e. superheated steam at atmospheric pressure but at temperatures above 100°C. Quantitative details are given for two important outlets in textile printing, viz. Procion (ICI) reactive dyes on cellulosic materials and disperse dyes on man‐made fibres, e.g. triacetate and Terylene. The mechanism of high‐temperature steaming is outlined and the economics of different steaming processes are discussed to show the potential advantage of the new process.
