Abstract
A textile composite is formed utilizing a latex composition formulated with granular starch dispersed uniformly throughout. The composite is subjected to suitable heating or drying conditions to gelatinize substantially all the starch particles thereby imparting to the composite improved cohesiveness.

A method of forming a textile composite comprising (A) forming an aqueous latex composition consisting essentially of (1) from about 30 to about 90 phrs latex and (2) from about 70 to about 10 phrs granular starch, (B) applying said aqueous latex composition to a fabric substrate to form a textile composite and then (C) treating said textile composite to increase bonding strength by producing uniform and substantially complete gelatinization of the starch at the interface with the substrate as well as throughout the latex composition by increasing the temperature of the textile composite to above the gelatinization temperature of the starch while retaining sufficient moisture in the composition to gelatinize the starch by maintaining said gelatinization temperature until substantially complete gelatinization is produced and finally (D) completely drying the textile composite having improved bonding strength.
A method of forming a textile composite comprising (A) forming an aqueous latex composite consisting essentially of (1) from about 40 to about 90 phrs latex, (2) from about 60 to about 10 phrs granular starch (3) from about 1 phs to about 20 phs of at least one starch gelation sensitizer and (4) from about 150 phrs to about 800 phrs filler, (B) applying said aqueous latex composition to a fabric substrate to form a textile composite and then (C) treating said textile composite to increase bonding strength by producing uniform and substantially complete gelatinization of the starch at the interface with the substrate as well as throughout the latex composition by increasing the temperature of the textile composite to above the gelatinization temperature of the starch while retaining sufficient moisture in the composition to gelatinize the starch until substantially complete gelatinization is produced and finally (D) completely drying said textile composite having improved bonding strength.
