摘要:
In dyeing nylon textiles with acid dyes, barre is reduced by using a synergistic mixture of a dye-leveling alkyl sulfonate and a dye-leveling alkyl aryl sulfonate.
摘要:
New condensation products of the formula ##STR1## wherein R represents alkyl, cycloalkyl, aralkyl, aryl, or halogen, M represents hydrogen, an alkali metal or alkaline earth metal or an ammonium group, and n is a number from 1 to 3; these products are particularly useful as dyeing assistants for dyeing synthetic polyamide fibres with anionic dyes.

Water-soluble fiber-reactive dyes, preparation thereof and use thereofDye mixtures which include the dyes of the general formula (1) and dyes of the general formula (2): their preparation and their use for dyeing or printing hydroxyl- and/or carboxamido-containing material, preferably fiber material.
摘要:
THE INVENTION RELATES TO THE DYEING AND PRINTING OF TEXTILE MATERIALS WITH CHLORINATED HYDROCARBON/WATER DYESTUFF EMULSIONS, THE AQUEOUS PHASE OF WHICH CONTAINS A SOLUTION OF WATER-SOLUBLE DYESTUFFS AND THE CHLORINATED HYDROCARBON PHASE OF WHICH MAY BE A SOLUTION OF DYESTUFFS SOLUBLE IN CHLORINATED HYDROCARBONS, AND TO AN AFTER-TREATMENT IN CHLORINATED HYDROCARON SOLUTIONS CONTAINING COMPOUNDS WHICH ARE INTERFACE-ACTIVE IN CHLORINATED HYDROCARBONS.
摘要:
The wet fastness of polyamides dyed with cationic dyes is improved by treatment with an aqueous solution containing soluble salts of the condensation product of formaldehyde and an aromatic sulfonic acid.
摘要:
An anhydrous dyeing process comprising (a) achieving a fabric padding in a dyeing bath having a small capacity and containing at least one polar organic solvent chosen so that it dissolves the coloring agents used sufficiently at room temperature (solvent A); (b) defiling fabric in a closed enclosure filled with vapors of another solvent C, non-miscible with A, having a boiling point lower than solvent A and in which the coloring agents used are insoluble; (c) then sending the textile material into another closed enclosure, brought to the boiling temperature, of solvent C, in which solvent C is evaporated and recovered; (d) then, after cooling and quick rinsing in a convenient solvent to remove the non-fixed particles of coloring agents and residual quantities of solvent A, circulating the fabric in a last heated enclosure in order to remove and recover the rinsing solvent and finally winding the dyed fabric, ready for use.
