Abstract: The invention relates to dispersing agents based on a mixture of at least one compound of the formula 1 in which Ar is benzene or naphthalene, X is -CH2-CH2- and/or -CH2-CH(CH3)-, 0 to (m-1) of the radicals A are hydrogen, 1 to m of the radicals A are benzoyl and/or naphthoyl, 1 to m of the radicals A are -CO-CM=CH-COOM and/or -CO-CH2-CH(SO3M)-COOM, M being a cation, R , R and R are hydrogen and/or alkyl having 1 to 14 carbon atoms, R is hydrogen and/or alkyl having 1 to 9 carbon atoms, n is a number from 1 to 150 and m is a number from 2 to 12, with compounds of the formula 2 in which R and R independently of one another are an alkyl group from methyl to butyl and are in the m-position relative to the hydroxyl group, R is hydrogen or methyl and Me is a cation, especially a proton or an alkali metal cation, alkaline earth metal cation or ammonium cation, and x and y are the numbers 0, 1 and 2, the total of these numbers being at least 1. The dispersing agents according to the invention are suitable for preparing dispersions of dyes, pigments, plant protection agents and pesticides and for preparing dyeing baths, padding baths and pastes for paper printing and textile printing.

Abstract: The very economical padding methods for applying liquid treatment agents and which have largely become established for flat-lying material are also interesting for dyeing and finishing tubular textile material. In the latter case, the use of this technique is however opposed by the finding that on impregnating circular-knitted goods on a pad mangle the squeeze edges are marked on both sides of the tube, which gives rise, for example, to undesirable color differences. According to the invention, this adverse phenomenon and the problems arising therefrom can be avoided if, through maintaining a relatively high liquor pick-up by the textile material and through mechanical shifting of the edges, the liquor is enabled to level out any unevenness produced on squeezing.

Abstract: Process and apparatus for applying in a continuous and level manner aqueous impregnating liquors to water-wet textile goods to prevent unlevelness of the liquor applied to the goods. This is accomplished by partly or completely exchanging the moisture on the goods by sucking or pressing liquor through the goods and by circulating the liquor to be applied while maintaining its volume and concentration at a constant value. The new technique makes it possible to dispense with the customary intermediate drying stage after the pretreatment.
