The acetamide is thoroughly mixed and wetted with the water and "Cellosolve" which acts as emulsifier and solvent. The mixture is quickly brought to a boil, then cooled to about 90F., and dispersed in a paint mill or similar device. The zirconium salts are dissolved and/or dispersed in water, along with any mineral wax which may be added.
Dispersion is facilitated by running the mixture through a colloid mill.
The so-prepared two mixtures are now blended and further dispersed by running them together through a colloid mill.
If desired, 10 to 15% by weight of a high-melting mineral wax, such as cerise wax, may be included, preferably by emulsification, with a corresponding reduction in the amount of water.
For the treatment of moderate-weight fabrics, for example, it has been found suitable to dilute the dispersion to 10 to 15% by weight of its original strength with warm or cold water before application. The dispersion mixture, diluted as required and preferably at about 100F., may be ap |
