    Abstract: Process for the single-bath dyeing or printing of unmodified polyolefin fibers with water-insoluble pigment dyestuffs by reacting under high-temperature dyeing conditions on these textile materials aqueous liquors or printing pastes containing solutions of pigment dyestuffs reversibly solubilized by cationactive compounds and, optionally, strong alkalis, and substances splitting off acid under heat, or dispersions of the salt-like addition products of dyestuffs having anionic character with cationic compounds, in the presence of a dispersion system on the basis of polyglycol ethers.

    Abstract: Process for the continuous dyeing of cotton piece goods containing portions of abnormal fibers, by impregnating the textile material for the purpose of covering these irregularities with a padding liquor which contains - in addition to suitable dyestuffs or components of developing dyestuffs - a cellulose ether, and then fixing the dyestuffs evenly on the fiber surface while precipitating (coagulating) said cellulose ether optionally with the action of the completing component for the development of the dyestuffs, by treating the goods with a solution of a salt or acid salt of a polyvalent metal or cation-active adjuvant.

    Abstract: A process for the dyeing of textiles consisting of wool without anti-felt finish or wool having an anti-felt finish in the form of a coating of a polyimine resin or a polyacrylic resin, or textiles containing such wool, with reactive dyes according to the exhaust method, which comprises dyeing said textiles in aqueous dyeing baths containing at least one commercial reactive dyestuff the starting pH of which is in the weakly acidic to neutral range, by heating rapidly to the dyeing temperature of 110 DEG to 125 DEG C. immediately after addition of the dissolved dyestuff, and by dyeing at this temperature for 10 to 20 minutes, while omitting the addition of pH-regulating substances during the whole dyeing operation.

    Abstract: Waste waters containing water glass, for example resulting from the dyeing of fabrics are purified by adding small amounts of basic nitrogen compounds, e.g. amines to the waste water and then carrying out the known flocculation process.

    Abstract: Process for the continuous dyeing and printing of piece goods made of synthetic polyamide fibers, preferably blended with cellulosic fibers, using reactive dyestuffs according to a thermofixing method, by applying onto the textile material an aqueous padding liquor or a printing paste, which has been weakly acidified by means of a buffer system of acetic acid and an alkali metal acetate and which contains a fiber-reactive dyestuff whose reactive groups have reversibly been masked by reaction with an alkali metal salt of an N-alkyl-aminoalkyl-sulfonic acid, and after drying of the material fixing the dyestuff on the two fiber components by means of dry heat.
