Abstract: Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.
Abstract: Light-polarizing films or foils, preferably based on a vinyl alcohol homopolymer or copolymer, contain dyes corresponding to the following formula ##STR1## in which R, R.sup.1, T.sup.1, T.sup.2, n, X and Z are as defined in the specification.

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: A process is described for fibre- and surface-level dyeing of wool and blends thereof with other fibers using a compound of formula (1) ##STR1## in which n is 0 or 1, and if n is 1, A is a radical of the formula ##STR2## and B is an alkylene or alkenylene group or a direct bond, or if n is zero, A is a compound of the formula ##STR3## Fibre- and surface-level dyeings, in particular in light to medium color shades are obtained by the dyeing process according to the invention. The dyeing aid according to this invention can be used to substitute formaldehyde containing wool dyeing aids.

Abstract: A method for dyeing fibrous material is provided. The method includes contacting a fibrous material with a carrier and a dye soluble or dispersed with the carrier in a dyebath. The carrier comprises an N-substituted aromatic carbonamide or an N,N-disubstituted aromatic carbonamide or mixture thereof. The carrier system of the present can be advantageously utilized for improving dye and flame resistant properties of difficult to dye fibers such as aromatic polyamide fibers, polybenzimidazole fibers and aromatic polyimide fibers.
Abstract: Low toxicity, biodegradable salt substitutes for use in dyeing of cotton and cotton blended fabrics. The salt substitutes are solubilized alkaline earth metal-organic complex compositions suitable to promote satisfactory dyeing. Preferably the composition is a mixture of magnesium acetate, magnesium citrate, and magnesium polyacrylate. After dyeing, a shift to alkaline pH in the wastewater treatment process allows for precipitation of the metal and the production of a biodegradable organic anion. The use of the salt compounds of the present invention in place of conventional sodium chloride or sulfate salts prevents the discharge of untreatable toxic wastewater into natural waterways.
Abstract: Compounds and mixtures of compounds obtainable by condensation of sulphonation products of defined alkyl-substituted naphthalenes and sulphonation products of optionally alkyl-substituted diphenylethers with formaldehye and optionally treated with further components, are valuable interface-active compounds suitable as assistants in various application fields, in particular as dispersing or levelling agents in the dyeing with disperse dyes or as tanning-assistants or dyeing-assistants for leather.

Abstract: Coupling products of diazotized o- or p-toluidines to 3-hydroxy-2-naphthoic acid p-anisidide do not produce optimum dyeing properties in HT exhaustion dyeing of wound packages of synthetic fiber materials. Filtration occurs time after time under critical conditions, since these single dyestuffs and also mixtures of these with one another build up too slowly in the heating-up phase.A bright red multi-component system of the same color shade, which exhibits a significantly improved exhaustion capacity by synergism during HT dyeing of wound packages and no longer presents difficulties in respect of filtration, can be obtained by mixing monoazo dyestuffs which are obtained by coupling diazotized aniline and p-toluidine in each case to 3-hydroxy-2-naphthoic acid p-anisidide.
