Abstract:
A cross linked graft polyester comprising the reaction product of a mixture of a polyunsaturated vinyl monomer with an acidic monovinyl monomer having at least one carboxyl group with an unsaturated polyester.
Abstract:
A hot-melt warp yarn size composition and a method for applying, desizing, and disposing of it which essentially eliminates atmospheric and water pollution at all stages of the process. The size is a melt blend of ethylene/vinyl acetate copolymer with microcrystalline, paraffin, or hydrogenated tallow wax. It is applied as a melt to warp yarn, desized with hot petroleum solvent, and the extracted size and unrecovered solvent burned to non-polluting carbon dioxide and water.
Abstract:
Process for anti-redeposition of staining substances on textiles of natural, synthetic or artificial fibers or mixtures thereof in the course of operations of dry cleaning or de-oiling by means of suitably stabilized perchloroethylene in which a sufficient amount of an additive represented by at least one monoketone compound having a boiling point below or equal to 160.degree. C. and, preferably lower than 140.degree. C., is added as an anti-redeposition additive.
Abstract:
A process for the bleaching and/or desizing of textile materials which comprises treating a textile material with hydrogen peroxide in the presence of a base, the hydrogen peroxide being applied as an emulsion of aqueous hydrogen peroxide in a hydrocarbon or halogenated hydrocarbon solvent.
Abstract:
THIS INVENTION PROVIDES A COMBINATION DESIZING, SCOURING AND BLEACHING PROCESS FOR GREIGE TEXTILES EMPLOYING AN AQUEOUS ALKALINE HYDROGEN PEROXIDE CONTAINING A DIPERSULFATE, A PERTROLEUM DISTILLATE FRACTION SOLVENT, A STABILIZER AND A SURFACANT.
Abstract:
THERE IS PROVIDED AN IMPROVEMENT IN THE PROCESS WHEREBY TEXTILE MATERIALS ARE SOLVENT SCOURED. THE SOLVENT IS FLASHED OFF AND THEREAFTER THE TEXTILE MATERIAL IS FINISHED OR DYED. THE IMPROVEMENT RESIDES IN APPLYING THE FINISH OF DYESTUFF IN THE FLASH-OFF STAGE OF THE KNOWN PROCESS.
