Abstract
Abstract Described herein is a process for preparing a foam composition having a coloring agent therein which is suitable for printing on a fabric. According to the invention, a foam growth inhibitor is added to a previously foamed composition having the coloring agent therein so as to restrict further foaming and substantially maintain the foamed composition at a desired blow ratio.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A process for preparing a foam composition suitable for printing on a fabric comprising the steps of: forming a foamable fabric printing composition comprised of a fabric coloring agent and a foaming agent in a liquid medium; foaming the composition to a blow ratio in the range of from about 2:1 to about 10:1 by incorporating an inert gas therein to provide a foamed fabric printing composition having a foam density in the range of from about 0.1 gm/cc to about 0.5 gm/cc; and introducing into the foamed fabric printing composition a foam growth inhibiting agent when said foamed composition is at a predetermined blow ratio, said inhibiting agent being introduced in an amount to substantially maintain the volume of the foamed composition and substantially restrict further foaming thereof thereby maintaining said foamed composition at a substantially constant blow ratio after introduction of said foam growth inhibiting agent therein.
Claim 2
Dependent Claim
149 words
A process for preparing a foam composition suitable for printing on a fabric comprising the steps of: forming a foamable fabric printing composition comprised of a fabric coloring agent and a foaming agent in a liquid medium; foaming the composition to a blow ratio in the range of from about 2:1 to about 10:1 by incorporating an inert gas therein to provide a foamed fabric printing composition having a foam density in the range of from about 0.1 gm/cc to about 0.5 gm/cc; and introducing into the foamed fabric printing composition a foam growth inhibiting agent when said foamed composition is at a predetermined blow ratio, said inhibiting agent being introduced in an amount to substantially maintain the volume of the foamed composition and substantially restrict further foaming thereof thereby maintaining said foamed composition at a substantially constant blow ratio after introduction of said foam growth inhibiting agent therein.
Claim 3
Dependent Claim
77 words
The method of claim 1 wherein said foam growth inhibiting agent is selected from the group consisting of aliphatic, alicylic, and mixed aliphatic and alicylic alcohols and hydrocarbons having C 6 -C 50 carbon atoms; amides and bis amides derived from C 1 to C 20 carboxylic acids; alkyl aryl, and other organo substituted poly-siloxane fluids and emulsions; organic esters of phosphoric and phosphonic acids fluids, powders and dispersions of polytetrafluoroethylene), and other organo substituted polyfluoroethylene compounds.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein said foam growth inhibiting agent is added in an amount of about 0.001 to 50 percent.
Claim 5
Dependent Claim
19 words
The method of claim 1 wherein said foam growth inhibitor is a C 9 to C 18 aliphatic alcohol.
