    Abstract: A material which is readily soluble in water and suitable for textile finishing is a solid mixture which contains not >0.3% by wt. free HCHO and contains at least two of the components urea, monomethylol urea and dimethylolurea in such proportions that the molar ratio of free and combined urea to combined HCHO ranges from 1:1.4 to 1:1.85. The mixture may be obtained by reacting urea and HCHO in the molar ratio 1:1.4 to 1:1.85 in aqueous solution at pH 6.5 to 8.5 at 30 DEG to 40 DEG C for 1/2 to 5 hours. The reaction mixture is then cooled to 15 DEG to 28 DEG C. and stirred at this temperature for at least 24 hours; the crystal mash obtained is spray dried. The crystal mash may contain at least 30% by wt. of dry residue. The pH of the reaction may be controlled by use of an organic base of medium strength, e.g. triethanolamine.ALSO:Textile materials are rendered crease resistant by treating with an aqueous soln. of a solid mixture which contains not >0.3% by wt. free HCHO and contains at least two of the components urea, monomethylolurea and dimethylolurea in such proportions that the molar ratio of free and combined urea to combined HCHO ranges from 1:1.4 to 1:1.85. The mixture may be obtained by reacting urea and HCHO in the molar ratio 1:1.4 to 1:1.85 in aqueous soln. at pH 6.5 to 8.5, at 30 to 40 DEG C for 1/2 to 5 hours. The reaction mixture is then cooled to 15 to 28 DEG C and stirred at this temp. for at least 24 hours; the crystal mash obtained is spray dried.

    Abstract: Coloured copolymers used in the sizing of textile materials comprise (a) 72 parts of ethyl acrylate, 10 parts of acrylamide, 7 parts of acrylic acid, 5 parts of methyl methacrylate and 6 parts of a dye having the formula which has been neutralized with caustic soda solution or (b) 70 parts of ethyl acrylate, 7 parts of methyl acrylate, 10 parts of acrylamide, 7 parts of acrylic acid and 6 parts of a dye having the formula which has been neutralized with caustic soda solution, the parts being by weight.ALSO:Yarns, filaments and threads of all types, e.g. of viscose rayon, cellulose acetate, polyesters, cotton, wool, polypropylene or polyacrylonitrile, are sized with a water-soluble film forming addition polymer which is combined with a dye by a covalent bond. Solubility in water is defined as the ability to form true or colloidal solutions with water. The coloured polymers which may subsequently be removed by washing may be water-soluble copolymers of olefinically unsaturated polymerisable colourless compounds and dyes bearing vinyl groups or water-soluble homopolymers or copolymers of olefinically unsaturated polymerisable colourless compounds which by virtue of reactive groups are combined with dyes which bear reactive groups. Water soluble copolymers prepared from (a) azo dyes or anthraquinone dyes which bear a vinyl group, of which numerous examples are given, as the coloured monomers, (b) water soluble monomers, e.g. acrylic, methacrylic, maleic or fumaric acids or their alkali metal or ammonium salts or amides, N-vinyl pyrrolidone, vinyl ethers, and 2-vinyl pyridine, N-vinyl-imidazole and 2-aminoethyl acrylate and salts and quaternisation products thereof, and optionally (c) monomers which form water-insoluble homopolymers, e.g. esters of acrylic, methacrylic, maleic or fumaric acid, acrylonitrile, vinyl esters, p vinyl or vinylidene chloride, styrene, butadiene, ethylene and propylene, may be used, the proportion of coloured monomer preferably being 1-8% by weight. Alternatively the coloured polymer may be prepared from a polymer formed from monomers which bear reactive groups which do not react under the conditions of the polymerisation, e.g. monomers having methylolamide groups and lower ethers thereof such as N-methylol acrylamide, and dyes bearing complementary reactive groups, e.g. carbamoyl groups or chlorine atoms, examples of which are given. The term "dye" is intended to include compounds which are exclusively or mainly absorbent and fluorescent in ultra-violet light.

    Abstract: An aqueous polymer dispersion suitable for use in the treatment of textiles is prepared by mixing while stirring a solution of methylolmethacrylamide dissolved in butylacrylate with a solution of potassium persulphate and the sodium salt of a paraffinsulphonic acid (C12-C18) in water at 80 DEG C. and holding the mixture at 80-90 DEG C. for about an hour, after the addition of further quantities of monomers, persulphate and sulphonate.ALSO:Cellulosic fibrous materials are crease-proofed, by impregnating them with an aqueous solution or dispersion of a substance having a molecular weight of up to 350 containing at least one N-methylol group and/or N-methylol ether group and with an aqueous solution or dispersion of an acid or potentially acid catalyst and reacting the N-methylol groups and N-methylol ether groups with each other, with other groups of the substances bearing them and/or with the cellulosic material in the presence of trioxane in an amount of 0.1-4 times the total molar amount present of the N-methylol groups and N-methylol ether groups. Suitable compounds containing N-methylol groups or N-methylol ether groups are those derived from compounds having the formulae:- in which X is a sulphur or oxygen atom, R1 and R2 are alkyl radicals having 1-5 carbon atoms, hydrogen atoms or radicals having the formulae, which are connected together directly or via radicals having the formula or is an alkyl radical having 1-5 carbon atoms, an aryl radical or a hydrogen atom, R4 is an alkyl group having 1-5 carbon atoms, a hydrogen atom, a hydroxy group or an alkoxy group having 1-5 carbon atoms or if the two groups are connected together direct, both R4 groups together may form the radical , R5 is an alkyl radical having 1-5 carbon atoms or a hydrogen atom, R6 is an alkoxy group having 1-5 carbon atoms, a hydrogen atom or a hydroxy group, R7 is a hydrogen atom or an alkyl or hydroxyalkyl radical having 1-5 carbon atoms, R8 is a hydrogen atoms an alkyl group having 1-5 carbon atoms or a radical of the formula -NHR11 and R9, R10 and R11 are alkyl groups having 1-5 carbon atoms or hydrogen atoms, or of the formula:- in which R12 and R13 are hydrogen atoms or alkyl radicals having 1-5 carbon atoms, A is a divalent hydrocarbon radical having 2 - 8 carbon atoms, x = 0 or 1, y = 0 or 1, z = 0 or 1 and (x + y) = 1 or 2.
