This paper was presented to the West Riding Region on 9 October 1980, and to the Huddersfieid Region on 3 February 1981. Foam application of dyes by printing or continuous methods offers potential savings in materials and energy, faster production and the possibility of ‘no wash–off processes. Factors affecting the composition and mechanical conditions required to produce stable foams have been examined in the laboratory and these foams have been applied to nylon carpets by rotary screen, horizontal pad, doctor roller and slots. Rates of fixation in steam of some acid dyes on nylon appear to be significantly faster using the foam application (ca. 50% pick–up) method compared with conventional methods (300–400% pick–up).
