Abstract: Red monoazo dyestuffs from diazotized 1-aminobenzonitrile or 1-amino-4-, 5- or 6-halo-benzonitrile and 2-amino-8-hydroxynaphthalene-6-sulfonic acid. These dyes are particularly distinguished by their good migration and leveling properties and excellent fastness to light. Said dyestuffs are moreover suitable for obtaining very even combination dyeings together with known blue, yellow and orange acid dyestuffs. These dyestuffs are particularly suited for the dyeing of carpeting, upholstery fabrics and drapery materials.

Abstract: A process for printing synthetic thermoplastic fibers, particularly polyester textiles, by applying to the fibers an aqueous dispersion of a non-ionic organic colorant, particularly a disperse dyestuff, and a thickener, subsequently drying the printed fibers, and finally heating the fibers to fix the colorant, wherein the aqueous dispersion contains less than 1%, preferably 0.2 to 0.5%, of a thickener of the formula ##STR1## WHERE R is hydrogen or lower alkyl,R.sup.1 and R.sup.2 are hydrogen, sodium, potassium, ammonium, mono-lower alkyl ammonium, di-lower alkyl ammonium, tri-lower alkyl ammonium, or tetra-lower alkyl ammonium,M is 0 or 1,N is 2 - m, andY is 5000 to 50,000.Textiles printed by this process do not require any soaping or afterwash to remove the thickener and any unfixed dyestuff in order to have full shade printings with excellent fastness properties.

Abstract: This invention relates to a dye carrier and to dyeing and printing processes which utilize said dye carrier. The dye carrier and the processes are particularly suitable for use in the dyeing and printing of synthetic organic fibers, notably the hydrophobic synthetic organic fibers. The carrier comprises phenyl cyclohexane or a derivative thereof having the general formula: ##SPC1##WhereR.sub.1 is hydrogen or lower alkyl andR.sub.2 is hydrogen, hydroxyl, lower alkyl, halogen or lower alkoxy.

Abstract: This invention relates to an improvement in the process for dyeing polyester or polyamide textile fibers with the dyestuff using a carrier, the carrier comprising a diphenylcarbinol of the formula ##SPC1##Where X.sub.1 and X.sub.2 independently are hydrogen, halogen or lower alkyl.

Abstract: An apparatus for the electrolytic generation of alkali on both sides of a substrate of hydrophilic material having applied thereto an alkali metal salt includes a pair of rollers positioned to rotate in contact with opposite sides of a substrate. Each roller has spaced around the periphery thereof a plurality of electrodes. Current of opposite polarities is applied to alternate electrodes on each roller, thereby to electrolytically generate alkali or acid on both sides of the substrate. The current may be DC, or alternatively may be AC at a low frequency. In an alternative arrangement the two rollers are replaced by a pair of endless belts of electrically conductive material positioned to move in contact with opposite sides of the substrate. An AC current at a low frequency is applied to the two belts, thereby to electrolytically generate alkali or acid on both sides of the substrate.
