Resum


Study is made of the influence o£ steaming and of shrinking treatments in an aqueous medium on the half dyeing time of high bulk Dralon and Courtelle yarns.
Study is further made of the influence of duration and temperature of the steaming treatment according to a pattern devised for the central rotational plans of two variables in an equation adaptable to experimental results.
The effect of the pretreatment on the absorption of cationic dyes was found to be greater on Dralon than on Courtelle.
