Abstract: In the washing-out of unfixed reactive dyes from cellulose fibres or their blends with other fibres, by aq. baths of 15-100 degrees C, an alkoxylated polyamine and with cloud point of a 1% aq. soln. of 18 degrees C min. is used. This is made by reaction of 100 parts amine with at least 2N atoms and at least one alkoxylatable gp. in an N atom, with 50-10000 parts of (a) ethylene oxide, and (b) propylene oxide or butylene oxide, or mixts. of (a) and (b) in molar ratio 0.2-5:1. Washing efficiency is improved over that of known nontoxic surfactants, resulting in better wash-fastness of the dyed prod.

Abstract: Dispersion dye prepns. contain (a) 5-40 wt. % one or more finely-divided dispersion dyes or optical brighteners, (b) 5-40 wt. % water-soluble surfactant from reaction of (i) ethylene oxide adducts of polyether diols made by polymerisation of butylene oxide T.H.F. or hexamethylene oxide in presence of acid or alkali, or (ii) adducts of ethylene oxide and propylene oxide on 2-10C diols, polyols and/or bis-(hydroxy cyclohexyl)methane or derivs., with 0.2-1 mol. chlorosulphonic acid, SO3 or sulpho-propionic anhydride per mol OH and subsequent neutralisation, (c) 5-30% usual anionic dispersant, and (d) 40-85% water opt. mixed with a water retention agent, or 10-90% (c) with no (d), and (e) opt. other usual additives. Used for dyeing or brightening of textiles contg. synthetic fibres, esp. wound yarns, e.g. cheeses, of cellulose ester or linear polyester fibres. The dispersions are stable and unchanged after prolonged storage at room temp. or many days at 60 degrees C. They are easily dispersed in water by stirring, and after long heating of dye baths at 110-140 degrees C, no dye flocculation or filtering of dye in outer yarn layers occurs.

Abstract: Pigment dyeing and flameproofing with organic phosphorus cpds. of textiles, is carried out in a single bath using one or more surfactants and pigment binders contng. polymerised units from monomers with hydrophilic gps. Use of non-ionic surfactants allows both processes to be combined in a single treatment. High concns. of flameproofing agent may be used without breaking of the emulsion under high shear forces.
