Other objects of our invention will appear from
the following detailed description.‘
In the coloration of textile materials it is very
desirable that the colors produced on the mate
rials be as fast as possible to light, washing, and
to other agencies such as acid fumes. Many dye

periods without any observed effect on the color.
Fabric or other textile materials treated in ac

increased ‘commercial value.

present in the solutions from 0.5 to 10% by weight
is frequently observed inthe case of many anthra

that in such solutions a 2% concentration of the

Advantageously, certain cation-active agents
may be applied to the textile materials prior to
or simultaneously with the application of the
acid-fading inhibitors. These agents not only
serve to improve the adherence .of the inhibitors
to the textile materials but also render the
treated textile .materials quite resistant to the
deleterious effects of washing. As a result, fab
rics which have been so treated may be washed

A cellulose acetate fabric, dyed as in Example

0.2% by weight of “Aero Catamine” which is at
a temperature of 50° C. and is maintained there

fabric is entered into an aqueous bath containing
