    Abstract: Hexahydro-triazines having the formula in which X represents chlorine or bromine are prepared by reacting a -chloro- or a -bromoacrylonitrile with formaldehyde. Other compounds containing a plurality of CH2=CXCO-groups (X being halogen) are prepared by reacting two moles of an acid halide CH2=CXCO.X with one mole of ethylene diamine, propylene diamine, butylene diamine, hexamethylene diamine or 1,4-diamine benzene-3-sulphonic acid, or three moles of the acid halide with one mole of diethylene triamine, triethylene tetramine or dipropylene triamine. All these compounds may be used in dyeing compositions (see Division D1). The polyamines may be reacted alternatively with an acid halide Y-CH2-CH.XCOX wherein X is halogen and Y is halogen or a quaternized nitrogen atom yielding products which in admixture with alkali may also be used in the dyeing compositions; reference is made in this connection to the tris-quaternary compound obtained by reacting hexahydro-1,3,5 - tris - (a ,b - dichloropropionyl) - S - triazine with a tertiary amine whereby each b -chloro-atom is quaternated.ALSO:The invention comprises compositions and a process for dyeing and/or fluorescent brightening of textile materials in which the material is treated in the presence of an alkaline-reacting agent with a dye or fluorescent brightener having one or more reactive hydrogen atoms preferably attached by nitrogen, oxygen or sulphur, or which is capable of forming one or more reactive hydrogen atoms during the process and with at least one uncoloured polyfunctional compound containing two or more groups of the general formula I:- H2C=CX-CO-in which X denote a halogen atom preferably chlorine or bromine attached to nitrogen or capable of forming two or more such groups during the process. Many types of dyes are specified and may be water soluble or insoluble but preferably contain primary or secondary amino groups, sulphonic amide groups, sulphonic alkylamide groups, hydroxyl groups or sulphydryl groups. Hydroxy-alkylene and amino-alkylene groups are referred to as are heterocyclic ring systems such as indole and triazole as sources of reactive hydrogen atoms. Reactive hydrogen atoms may be obtained by conversion of methylene ether or ester groups to methylol groups. Reactive dyes are specifically referred to. The uncoloured polyfunctional compounds include derivatives of 1, 3, 5-S-triazine and of various diamines and triamines. Compounds which may form the required groups of Formula I are those which have the groups of formula:- -CO - CHX -CH2 - Y in which X is halogen preferably chlorine or bromine and Y is halogen or a quatermixed nitrogen atom. Fixation of the dyes on the fabric is at room temperature or by steaming or dry heating at temperature of up to 200 DEG C. Conventional methods of application are used and dispersing agents, dyeing or printing auxiliaries may be used. Alkaline reagents used are alkali metal hydroxides or salts of weak acids, also organic reagents include pyridine and benzyltrmethylammonium hydroxide. Fabric treated include, cellulose acetate, polyacrylonitrile and its copolymers, polyesters, wool, silk and linear polyamides.

    Abstract: Textile materials are dyed and/or printed by treating the materials, if necessary at elevated temperatures, in the presence of an alkaline-reacting agent with at least one dye which contains one or more reactive hydrogen atoms, preferably attached by way of N, O or S atoms, or which is capable of making such H atoms available during the process, and with at least one uncoloured polyfunctional compound having the general formula: in which at least two substituents A are an X-CH2-CH2-CO- group where X is the radical of a 2 DEG amine attached by way of nitrogen and the other A may be a H2C=CH-CO- or Z+ -O3S-CH2-CH2-CO- group where Z is a cation. The radicals X may be the same or different and may be radicals of dimethylamine, diethylamine, diethanolamine, piperidine, pyrrolidine, morpholine, pyrrole or imidazole and Z may be H, NH4, Na or K. The alkaline-reacting agent, the dye and the polyfunctional compound may be applied successively in any sequence but are preferably applied simultaneously. The dyebath or printing paste may further contain dispersing agents, protective colloids and/or printing auxiliaries. The dyeings may be fixed by steaming or dry-heating at 100-130 DEG C. or 140-160 DEG C. respectively and finished off normally. Examples of dyeing and printing cotton, spun rayon and acrylonitrile fabrics are given.
