Compositions of water insoluble U.V. absorbers can be improved by the addition of a non-ionic surfactant which is an addition product of ethylene oxide or propylene oxide or both ethylene oxide and propylene oxide, and a mixture of fatty alcohols, fatty acids or fatty esters having 7-20 carbon atoms, preferably 14-18 carbon atoms or either tristyrylphenol or distyrylphenol. Such compositions have a good storage stability and excellent shear stability when the substrate to be dyed is a yarn which is in packed form.

Aqueous dispersions (D) of a wax (W) dispersed in the aqueous phase by means of a dispersant (B), wherein in (D) the wax (W) is

Wet-slippage of textile material and wet lubricant therefor

A process for dyeing a mixed fibre substrate with at least one disperse dye and at least one metal complex dye selected from direct dyes and reactive dyes characterized in that dyeing is carried out in the presence of a compound of formula I ##STR1## in which X is --S--, --O--, or --NH--;

Dyeing process

A process for applying a reactive dye to a cellulosic substrate comprising:

Process for reactive dyeing a cellulose-containing textile material with

The invention provides a process for the exhaust dyeing with a reactive dyestuff of a textile material comprising cellulosic fibres, which process comprises the step of adding to the dyebath containing the reactive dyestuff, simultaneously the salt and the alkali in specified quantities metered per unit time so as to give a substantially linear exhaustion of the dyebath.

Exhaust dyeing of cellulosic substrates with reactive dyes controlled

The invention relates to a process for exhaust dyeing a textile fibre substrate to obtain level dyeings, which process comprises the step of adding to the dyebath the effective amount of dyestuff or electrolyte or dyestuff and electrolyte either simultaneously or one after the other in specified quantities per cycle of the dyeing machine, metered according to a mathematical function.

Process for exhaust dyeing a textile fiber material: controlled addition

Dyeings on cellulose with direct or reactive dyestuffs are given improved wet fastness properties by aftertreatment with a reaction product or mixture of a polybasic amino compound (A) with an N-methylol compound (B) or with formaldehyde or a formaldehyde donor and optionally a crosslinking catalyst (C). Particular direct or reactive dyestuffs and polybasic amino compounds are determined to be suitable in the dyeing and aftertreatment when the dyestuff and the polybasic amino compound (A) are such that when mixed together in aqueous solution they give a precipitate which, after washing and drying does not redissolve in aqueous alkali at pH.gtoreq.12 at room temperature.

Method for determining the compatibility of a direct or reactive

The invention relates to a process for continuous dyeing a cellulosic fibrous substrate with a direct or reactive dye comprising the steps of

Continuous dyeing process which provides improved wetfastness:

The present invention relates to an after-dyeing treatment process for synthetic/cellulosic fibre mixed substrates which have been dyed with at least one disperse and at least one reactive dye in which after fixation, the dyed or printed substrate is reductively treated at a neutral to alkaline pH with an aqueous solution containing reducing agent, whereby non-bound disperse dyestuff is decomposed such that it does not re-build up on the substrate whilst the fixed reactive dyestuff remains substantially unaffected.

Reduction clearing of disperse dyes

A process for dyeing or printing with a fibre-reactive dyestuff a substrate consisting of or comprising cellulosic fibres, which process comprises treating the dyed or printed substrate, at a temperature from 20.degree. to 105.degree. C. with an aqueous solution of a polymer containing carboxylic acid groups at least partially neutralized in salt form.
