Abstract
Foams containing a functional textile treating compound for application to a substrate such as a fabric or textile. The use of foams enables the application in uniform manner of many functional compositions that can be used in the treatment of a textile fabric to improve its properties. The foam compositions of this invention generally leave the textile material essentially dry to the touch and thus require less energy consumption in drying and further treatment of the textile. The foams have a foam density of 0.005 to 0.3 gram per cc, and average bubble size of from 0.05 to 0.5 millimeters in diameter and a foam half-life of from one to sixty minutes.
Claims5
A froth composition for continuously and directly surface treating a fabric or paper substrate, said composition being a froth having a foam density of from 0.005 to 0.3 gram per cc, an average foam bubble size of from 0.05 to 0.5 millimeters in diameter and a foam half-life of from 1 to 60 minutes, said foam composition comprising from 5 to 75 weight percent of functional textile treating compound, from 0.2 to 5 weight percent of frothing agent, from 0 to 5 weight percent of wetting agent, with the balance of said composition being water, said percentages based on the weight of said foam composition;
- said foam further characterized in that it immediately breaks on contact with said substrate and is rapidly absorbed thereby to leave the surface thereof essentially dry to the touch.
