Abstract: The present invention relates to a fabric treatment composition comprising surfactant, fabric substantive dye and dye auxiliary agent. The fabric treatment composition of the invention can be used to change, refresh or maintain the color of fabric.

Abstract: A process for introducing additives into a polymer melt comprising dispersing at least one additive in an at least partially volatile liquid vehicle with a dispersant and a stabilizer for the dispersion; feeding the resulting dispersion to a vented extruder which is extruding a polymer; and removing the fed volatiles through the extruder vent to achieve a substantially homogeneous system containing the polymer and at least one additive is disclosed.

Abstract: A method for locally enhancing the contrast of a yellow image, which method comprises providing a yellow image on a white background, said image comprised of yellow areas and white areas, said yellow areas and white areas exhibiting pH levels which differ by at least 0.5 in an aqueous environment, applying to at least a portion of said yellow image a solution of a pH color changing dye which will change color to a color other than yellow when coated on one of said yellow areas or white areas and not change color when coated on the other of said yellow areas or white areas, thereby forming a colored image duplicating the yellow image in areas where the solution has been applied, said colored image having a visually better contrast than said yellow image.

Abstract: A process for preparing a thermosensitive fibrous structure which includes adding a fibrous substrate mainly composed of cellulosic fiber, microcapsules including a thermochromic material, a cationic surfactant and a nonionic surfactant to a dye bath maintained at a temperature of not higher than 90.degree. C. and then adding an agent for imparting exhaustion property in the bath at a pH not more than 7, thereby causing the fibrous substrate to exhaust the microcapsules from the bath. According to this process, there can be obtained a thermosensitive fibrous structure wherein microcapsules are almost completely exhausted and uniformly provided.

Abstract: The invention relates to novel pasty or solid dye melts which contain, per 1 part of a sparingly water-soluble or water-insoluble dye whose melting point is higher than 150.degree. C., 2 to less than 5 parts of a nonionic surfactant with a melting point of 25.degree.-100.degree. C. and having an HLB value of 13 to 19 or of a cationic surfactant with a melting point of 25.degree.-100.degree. C., or a mixture of said surfactants, to a process for their preparation and to the use of said melts, preferably for dyeing and printing polyester materials, to give level dyeings having a high degree of exhaustion.

Abstract: An aqueous cleaning composition comprising a surfactant; up to about 50% of a higher boiling solvent, typically an alkyl ether of an alkylene glycol, said solvent introducing impurities into the composition in an amount and of a nature normally chemically incompatible with oxidizable dye chromophores; a dye in an amount to provide a desired tinctorial value, and a stabilizer selected from the group consisting of salts suitable to provide iodide and thiosulfate anions in an amount effective to retard fading of the dye, said compositions having a basic pH when the stabilizer is the thiousulfate salt. In another aspect of the invention, the stabilizer incorporated into compositions containing a solvent, a surfactant, and water, and optionally a dye provides a beneficial cleaning result. In yet another aspect of the invention, the stabilizer beneficially retards the development of malodors when the compositions of the present invention are contained in a PVC container.

Abstract: A process is described for dyeing hydrophobic fibre material with unfinished disperse dyes from an aqueous liquor, which comprises dissolving one or more such dyes in water at a temperature of 50.degree. to 150.degree. C. by means of a surfactant or surfactant mixture with a hydrotroping or solubilizing action on disperse dyes, bringing the dye solution together with the substrate in a dyeing apparatus, then heating the dyeing liquor to the dyeing temperature and completing the dyeing at that temperature and then removing the substrate and restoring the exhausted dyeing liquor to the original composition by adding water, surfactant and dye and using it again for dyeing.

Abstract: This invention relates to a unique, efficient, concentrated synthetic thickener composition comprising a high molecular weight carboxyvinyl polymer, hydrocarbon solvent and cationic surfactant, a thickened concentrate formed by alkaline neutralization of said composition, an aqueous paste (cut clear) formed by dilution of said concentrate, textile print pastes containing said concentrate, and a method of thickening an aqueous system.
