    Abstract: 1,141,515. Mixed aminoplast textile treating compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 25 Nov., 1966 [27 Nov., 1965; 8 June, 1966], No. 52871/66. Heading C3R. [Also in Division D1] A composition suitable for use in the treatment of cellulosic fabrics comprises (a) at least one poly-N-methylol compound which condenses at a temperature less than 140‹ C., (b) at least one poly-N-methylol compound which condenses at a temperature of at least 140‹ C. and (c) at least one acid curing catalyst which forms an acid under the conditions of condensation. The poly-N-methylol compounds contain two or more hydroxymethyl or alkoxymethyl groups having 1-5 carbon atoms in the alkoxy group which are attached to nitrogen. The compounds (a) may have the formula in which each R 1 is a hydrogen atom or when taken together the two substituents R 1 denote and the substituents R 2 which may be the same or different are hydrogen atoms or alkyl groups having 1-4 carbon atoms and the compounds (b) may have the formula or in which R 3 is a hydrogen atom or alkyl group having 1-4 carbon atoms, R 4 is R 5 is a hydrogen atom, an alkyl group having 1-4 carbon atoms or a group of the formula R 3 O-CH 2 -, R 6 is an alkylene group having 2-4 carbon atoms, R 7 is methyl or ethyl and n is 0 or 1, the compounds containing at least two R 3 O-CH 2 - groups. The acid curing catalyst may be aluminium sulphate, zinc chloride, zinc nitrate, ammonium chloride, ammonium nitrate, ammonium phosphate and salts of ethanolamine, diethanolamine, 2- hydroxy - 2 - methylpropylamine with hydrochloric acid, magnesium chloride and magnesium sulphate. The compounds (a), (b) and (c) may be applied to the fabrics from an aqueous bath which may also contain wetting agents, e.g. salts of alkylnaphthalene sulphonic acids, alkali metal salts of sulphonated dioctyl succinate and adducts of alkylene oxides with fatty alcohols, alkyl phenols or fatty amines, water repelling agents, e.g. paraffin wax emulsions containing aluminium or zirconium, silicon containing formulations and perfluorinated aliphatic compounds, softeners, e.g. ethenoxylation products of high molecular weight fatty acids, fatty alcohols or fatty amides, high molecular weight polyglycol ethers and esters thereof, high molecular weight fatty acids, fatty alcohol sulphonates, stearyl-N,N-ethyleneurea and stearylamidomethyl pyridimium chloride, finishes, e.g. cellulose ethers and esters, alginates, polyamides, ether-oxylated polyamides, polyvinyl ethers, polyvinyl alcohol, polyacrylic or methacrylic acid or esters or amides thereof, polyvinyl propionate, polyvinyl pyrrolidone, copolymers of vinyl chloride and acrylic esters, butadiene and styrene or acrylonitrile, α-dichloroethylene, #-chloroalkyl acrylic esters or vinyl-#-chloroethyl ether and acrylamide or amides of crotonic or maleic acid, or N-methylolmethacrylamide and other polymerizable compounds, or polyethylene, and optical brighteners. In examples the aminoplast mixtures are: dimethylol ethyleneurea plus (1) dimethylol glyoxal monoureine or (2) dimethylol ethyl - urethane or (4) dimethylol urea and dimethylol glyoxal monoureine; or (3) dimethylol propyleneurea plus dimethylol 4-methoxy-5: 5- dimethylpropyleneurea; or (5) dimethylol glyoxal monoureine plus dimethylol 5-isobutyl hexahydro - 1: 3: 5 - triazinone - 2. These are used in aqueous solution containing MgCl 2 or Mg(SO 4 ) 2 and optionally polyethylene emulsion and/or a copolymer of butyl acrylate/butylene diacrylate / methylol methacrylamide / acrylamide and optionally ethoxylated iso-octylphenol.

    Abstract: 1,221,849. Fire-proofing. BADISCHE ANILIN-& SODA-FABRIK A.G. 1 July, 1968 [5 July, 1967], No. 31242/68. Heading D1P [Also in Division C2] Cellulosic fibrous materials are given a washresistant fireproof finish by applying thereto a composition consisting of a mixture of phosphoric amides having the general formula: wherein a is from 0.1 to 2.6, b is from 0.3 to 2.0 and c is from 0.1 to 1.0, the total of a b and c being 3.0. The flameproofing agent is generally used in a 5 to 50% by weight aqueous solution, the amount being such that the fibrous material absorbs from 5 to 50% by weight (with reference to the dry weight of the fibrous material) of the mixture of phosphoric amides. Application of the fireproofing agent to the fibrous material may be by dipping, spraying or padding. After the impregnated fibrous material has been dried, the agent is fixed thereon by. heating for two to twenty minutes at 100 to 200‹C. Following this, any un-fixed agent is removed e.g. by washing with hot dilute aqueous alkali-metal hydroxide solution or alkali metal carbonate solution. Cellulosic fibrous materials mentioned are cotton, linen, sisal, hemp, regenerated cellulose and wood-wool in the form of filaments, threads, fibres, wadding, non-woven fabrics or sheet materials such as textiles and papers. These materials may be mixed with others e.g. wool, silk, polyester, polyamide or polyacrylonitrile. The fireproofing agent may be used in admixture with other textile finishing agents e.g. aminoplast-forming monomeric, oligomeric and polymeric compounds.

    Abstract: Dirt-repellent textiles. Copolymers of (a) 12-63% of at least one polymerisable mono- or dicarboxylic acid, (b) 0.1-5% of at least one opt. etherified and/or esterified N-methylolamide of a polymerisable mono- or dicarboxylic acid, (c) 35-80% of at least one monomer CH2=CR-COO (CH2CH2O)n-R1 (where R is H, methyl or Cl; R1 is H or 1-4C alkyl and n is integer 2-40) and opt. (d) bal. up to 100% one or more co-monomers, are used for dirt-repellent finishing of natural and synthetic textiles, by impregnation; reaction by heating, pref. in presence of cross-linking catalysts, and pref. together with crease-proofing agents.
