Definitions

• the reaction is then finalized at a temperature from 30 to 100 C, preferably from 45 to 70 C and, if desired, water is distilled out of the mixture formed.
• the heterocyclic compound used as starting material in the present process must be practically colourless and contain at least one, preferably only one, heterocycle which may be altogether the only ring of the compound or, for example, may also contain a fused-on aromatic six-membered' ring.
• Specially useful are compound with six-membered hetero rings, especially those whose ring contains 2 or 3 nitrogen atoms and 4 or 3 carbon atoms, such as pyridazine, pyrimidine, quinazoline and especially 1,3,5-triazine compounds. These compounds contain at least 2 halogen atoms linked with carbon atoms of the hetero ring, for example bromine or preferably chlorine atoms.
• thiourea compound containing at least one hydrogen atom linked with nitrogen or preferably thiourea itself or an alkali metal or ammonium hydrogensulphide, as well as a monoalkanolamine or dialkanolamine containing l to 4 carbon atoms, preferably monoor diethanolamine.
• the reaction is performed in an aqueous medium that may contain apart from water organic solvents, especially those which are water-miscible. There may be mentioned lower alcohols and acetone.
• the reactions are performed within the temperature range from --l0 to +30 C; in the presence of an organic solvent the reaction temperature may be below 0 C, whereas when purely aqueous reaction media are used it is advantageous to react at 0 C or slightly higher.
• reaction medium reveals a pH value of about 7.
• the reaction is then finalized at a temperature from 30 to 100 C, preferably from 40 to 70 C, and may be terminated after 2 to 3 hours.
• the pH value of the reaction mixture during this time should be within the neutral or slightly alkaline region. A dropin pH value impairs the solubility of the reaction product substantially and can be prevented by adding more alkali.
• the condensates are also obtained, when in an aqueous medium at a temperature from 10 to +25?
• a colourless heterocyclic compound that contains at least 2 nitrogen atoms in the hetero ring and at least 2 halogen atoms linked with carbon atoms of the hetero ring is reacted with a thiourea compound and on completion of this first reaction stage, without intermediate separation, for every mol of heterocyclic halogen compound used 0.5 to 1.5 mols ofa monoalkanolamine'are added, while maintaining a pH value from 6 to 10 and keeping the temperature of the reaction medium first for at least 8 hours at 30 to C and then for at least 5 hours at to C and, if desired, the water is distilled out of the mixture formed.
• each of this halogen compound a total of about 4 mols of monoacidic base, thus for instance 3 mols of alkali metal hydroxide and lmol of alkanolamine, is consumed.
• the amount of water used as reaction medium may be freely chosen within a wide range, advantageously so that, on one hand, the reaction mixtureis easy to stir from the start and the risk of heating beyond the prescribed temperature range is obviated and that, on the other hand, excessive dilution does not make the practical performance problematic.
• the heterocyclic halogen compounds are sparingly soluble in the water serving as reaction medium, it is advantageous first to convert them into a finely distributed state, which can be done in known manner by dissolution in an organic watermiscible solvent such as acetone and pouring the solution out over ice,
• the molecular ratio heterocyclic halogen compound sulphurcontaining compound should range from 1 2 to l 0.5, preferably from 1 11.5 to l 0.5
• the molecular ratio of heterocyclic halogen compound alkanolamine should likewise be within the range from 1 2 to 1 0.5, preferably from 1 l.5 to l 0.5.
• cyanuric chloride particularly good results are obtained by using equimolecular proportions or amounts of the three reactants differing only little therefrom.
• the resulting product can be used as it is for thepurpose indicated above.
• concentration of the mixture which is not very high at the end of the reaction, it is, however, advisable to remove the water completely or partially by distillation under vacuum. In this manner generally stable products are obtained which are at most only slightly tinted and are readily and completely soluble in water.
• the products obtained by the process described above are suitable, as has already been said, for use in combination with aminoplasts in textile finishing, especially for improving the shape retention.
• Particularly suitable for such a treatment is textile material of cellulose, if desired in combination with other fibres, for example polyester fibres. Therefore, according to a preferred use of the products of this invention textile materials are impregnated with an aqueous preparation containing a curable aminoplast precondensate, a curing catalyst and a condensate of the composition defined above, whereupon the textile material is dried and hardened by treatment at an elevated temperature.
• Aminoplast precondensates are adducts of formaldehyde with methylolable nitrogen compounds.

• symmetric alkyltriazones biuret, thiourea, alkylcarbamates, guanidine, alkylor aryl-ureas and -thioureas, alkylene ureas or diureas, for example ethyelne urea, propylene urea or acetylene diurea; 4,5-dihydroxy-imidazolidone-2 and its derivatives, for example the 4,5-dihydroxyimidazolidone-Z substituted in 4-position on the hydroxyl group by the residue CH CH CON- H-CH -OH.
• methylol compounds of urea and of melamine are preferred and in the case of melamine compounds those ofa low or high degree of methylolation may be used. It is also possible to use compounds whose methylol groups are more or less completely etherified, for example, with methyl groups.
• the conventional acid or potentially acid compounds may be used, such as ammonium chloride, magnesium chloride or zinc fluoroborate.
• the preparation used for finishing the textile materials contains in addition to the aminoplast precondensate, the curing agent and the condensate of this invention also an emulsion polymer prepared from an N- methylolamide of an a,B-ethylenically unsaturated carboxylic acid or an ether of such a methylolamide and an alkaline earth metal salt of an a,,B-ethylenically unsaturated monocarboxylic acid, especially the copolymers, obtained in an aqueous emulsion, from a. 0.25 to percent by weight of an alkaline earth metal salt of an a,,B-ethylenically unsaturated monocarboxylic acid (for example calcium acrylate),

• the proportions of the ingredients of the aqueous preparations may vary within wide limits and may be adapted to the purpose in hand. In general it is indicated to use for 10 parts of aminoplast precondensate 1 to 4 parts of condensate from heterocyclic halogen compound, thiourea and alkanolamine. Otherwise, the textile material may be treated in the usual manner.
• undyed or dyed fabric or tricot may be impregnated on a padder with the preparation and, advantageously after an intermediate drying operation at a temperature of up to 100 C, subjected to a treatment with dry heat of l-l80 C for 2 to 20 minutes, the temperature and the duration of the treatment being adapted to the purpose of the treatment which may be, for example, an improvement of the wet fastness properties for direct dyeing dyestuffs, an anti-crease finish or permanent shaping (permanent press).
• the finishing operation may also be combined with a dyeing operation, for example so that the impregnating solution further contains a dyestuff which, by virtue of special substituents, is reactive towards the fibre or more especially towards the aminoplast precondensate and, by virtue of this property, is fixed on the substrate during the heat treatment or even before it.
• a dyestuff which, by virtue of special substituents, is reactive towards the fibre or more especially towards the aminoplast precondensate and, by virtue of this property, is fixed on the substrate during the heat treatment or even before it.
• an aminoplast resin finish impairs the mechanical properties of cellulosic fibrous materials, especially their tensile strength and abrasion resistance; in general the loss in strength is the greater the higher the content of aminoplast and the more energetic the hardening is.
• these serious drawbacks can be substantially prevented with the aid of the new condensates or at least they can be reduced to an acceptable degree.
• these condensates improve the soil release from the fibre.

The paste is introduced into a solution which has been prepared at C from 76 g (1 mol) of thiourea and one-half litre of water and has then been cooled by adding one-half kg of ice.
