Abstract:
Fibrous materials of synthetic polyamides or cellulose esters are capable of optical brightening according to the so-called thermosol process (padding at ambient temperature with subsequent fixation by a heat treatment) when fixing in the presence of an auxiliary consisting of a polyalkylene glycol and a fatty alcohol oxethylate. Optionally foam-depressing phosphoric acid alkyl esters and branched carboxylic acid esters are used additionally.
Abstract:
A process for the simultaneous dyeing and crease-proof finishing of textile material consisting of cellulose fibers or blends of cellulose fibers and polyester fibers by impregnating the textile material with an aqueous bath containing a reactive or vat dyestuff or a disperse dyestuff and a reactive or vat dyestuff, N-methylol-acrylamide or N,N-dimethylol-methyl-bis-acrylamide or an ether thereof with an alkanol containing 1 to 3 carbon atoms as well as an acid catalyst, dry heating the material to condense the N-methylol group of the synthetic resin and optionally fixing the disperse dyestuff at the same time, and in a second fixation step simultaneously fixing the reactive or vat dyestuff and the ambivalent cross-linking agent in an alkaline medium, and then after-treating the material by washing operations.
Abstract:
NAPHTHALENE-BIS-2-BENZIMIDAZOLES, ESPECIALLY 1,4-NAPHTHALENE-BIS-2''-BENZIMIDAZOLES, ARE EXCELLENT OPTICAL BRIGHTENERS, PARTICULARLY FOR FIBROUS MATERIALS, ESPECIALLY FOR THOSE MADE OF POLYACRYLONITRILE. THE NEW COMPOUNDS ARE USEFUL FOR BRIGHTENING IN COMBINATION WITH OXIDATIVE BLEACHING AGENTS IN ACID BATHS.
Abstract:
FIBROUS MATERIALS MADE OF POLYMERS CONTAINING AT LEAST 85% OF POLYACRYLATONITRILE CAN BE OPTICALLY BRIGHTENED IN A SAID MATERIAL WITH A LIQUOR CONTAINING A 1-(4''-B-ALKOXYETHYL SULFONYL)-PHENYL-3-B-CHLOROPHENYL-$2-PYRAZOLINE, ADJUSTING THE IMPREGNATED MATERIAL TO A LIQUOR CONTENT OF ABOUT 5 TO 120% BY WEIGHT REFERRED TO THE DRY-WEIGHT OF THE GOODS, AND HEATING IT FOR ABOUT 2 SECONDS TO 30 MINUTES TO A TEMPERATURE OF ABOUT 100 TO 150*C.

Abstract:
A MIXTURE OF 1,4-NAPHTHALENE-BIS-(2''-BENZOXAZOLES) AND OF P-SUBSTITUTED 2-STYRYL BENZOXAZOLES IN THE FORM OF AN AQUEOUS DISPERSION SHOWS A HIGHER BRIGHTENING EFFECT ON FIBROUS MATERIALS WHICH ARE, AT LEAST PARTIALLY, OF SYNTHETIC ORIGIN, THAN THE TWO COMPONENTS. THE TWO COMPONENTS ARE USED IN A RATIO OF 0.1 TO 10 PARTS BY WEIGHT OF STYRYL BENZOXAZOLE PER EACH PART BY WEIGHT OF NAPHTHALENE DERIVATIVE.
