  • Patent number: 4153561
    Abstract: Compositions in the form of aqueous emulsions containing salts of N-alkyl-.alpha.-sulfosuccinic acid amides, fatty acid amide sulfates or glycerin ether derivatives, polyethylene glycols and non-ionic dispersing agents. These emulsions are very stable to storage. They are used for the treatment of textile materials. Preferably they are added to the padding liquor in continous pad-dyeing or printing processes for textiles including carpets of synthetic fibers. They can also be used in space-dyeing processes. They give a soft feel to the textiles treated therewith and also provide a good wetting of the textile goods. On synthetic fibers also an anti-soiling effect has been observed.
