    Abstract: A uniform condition of swelling in fibrous materials during a thermal treatment is achieved by carrying out the thermal treatment in a gas which does not attack the fibrous material and which contains a definite and constant amount of water vapour which is between 1 and 500 g/cu.m but does not contain any liquid water. The gas containing a definite water vapour content may be obtained by bringing a gas which does not attack the fibres, e.g. nitrogen, carbon dioxide, combustion gases or air, into intimate contact with water or aqueous solutions whose temperature is kept constant and providing a large surface of contact between the gas and liquid phases by spraying the water of aqueous solution in fine dispersion into the flowing gas or by bubble tray columns in which the gas is forced through one or more relatively small openings into the water or aqueous solution and during ascent through the liquid, the gas bubbles absorb water vapour. The saturation of the gas with the water vapour may be carried out at a constant temperature of between -20 DEG and +95 DEG C. Purified water, river water or industrial waste waters or mixtures of water with high boiling point substances, e.g. phosphoric or sulphuric acid, sodium sulphate, sodium chloride, sodium phosphate, sodium borate, calcium chloride, sodium acetate, glycols and polyglycols may be used. After the thermal treatment of the fibrous material it may be cooled in a gas having a temperature of 10-50 DEG C. and a constant water vapour content equivalent to a relative humidity of 65-95%. The treatment may be applied to the crease proofing of cotton and regenerated cellulose fabrics with heat curable aminoplasts, formaldehyde, dihydroxy ethyl sulphone, methylol compounds of glycols, triazinones, ethylene urea and its hydroxyl or alkoxyl derivatives, propylene urea and its derivatives or acetone in the presence of alkaline, acid or potentially acid condensation catalysts, to the thermo fixation of reactive dyes on fibres, e.g. cotton, and to the dimensional stabilization of synthetic fibres, e.g. cellulose triacetate, polyamide and polyester fibres.

    Abstract: Textile fabrics which contain at least 25% by weight of cellulosic fibres, e.g. cotton and viscose rayon, are treated with an aqueous liquor which contains (a) a reaction product of an aminoplast-forming substance with formaldehyde which contains in the molecule at least two nitrogen atoms and, connected to nitrogen, at least two methylol groups or etherified methylol group and (b) a copolymer from 1-25% by weight of a compound of the general formula in which R1 stands for -H or -CH3, and 99-75% by weight of an ester formed from an acid in which R2 stands for -H or -CH3 and a monohydric saturated aliphatic alcohol with 1-5 carbon atoms, and are then subjected, conveniently after drying, to a mechanical treatment, e.g. embossing, pleating or schreinering, at a temperature of 140 DEG -210 DEG C. and heated to above 100 DEG C. up to 200 DEG C. The fabrics may be dried before the mechanical treatment at 70 DEG -150 DEG C. until they have a residual moisture content of 6-14% by weight. In addition to the acrylic and methacrylic acid esters, other copolymerisable compounds, e.g. vinyl chloride, vinyl esters and ethers made from acids and alcohols having 1-5 carbon atoms, butadiene, vinyl lactams, such as pyrrolidone or caprolactam, styrene and substituted styrene, may be used for the preparation of the copolymer. Specified aminoplast precondensates are tetramethylol glyoxal diureine, dimethylol urea dimethyl ether, dimethylol ethylene urea, dimethylol N-alkyl triazinones, dimethylol urea, dimethylol glyoxal mono ureine, dimethylol butane-diol diurethane and di-, tri- and hexamethylol melamines. The composition may also contain a dispersing agent, e.g. a reaction product of iso-octylphenol or a fatty acid monoethanol amide with ethylene oxide, and as hardening catalyst ammonium nitrate, chloride or sulphate, mono- or di-ammonium phosphate, zinc nitrate or magnesium chloride. The mechanical treatment may be carried out immediately following drying or impregnation or the impregnated fabric may be allowed to lie for hours or days and then subjected to the mechanical treatment.

    Abstract: The fastness to rubbing of vat, azoic, reactive or pigment dyeings or prints on cellulose-containing textile materials is improved by aftertreating with an aqueous dispersion of a copolymer obtained from a mixture of 1%-25% by weight of an etherified or unetherified N-methylol amide of acrylic or methacrylic acid with 99%-75% by weight of one or more other components capable of copolymerising therewith, and then heating to at least 120 DEG C. The process is applicable to textiles containing, in addition to cellulose fibres, fibres of polyamides, polyacrylonitrile, polyesters, cellulose esters, regenerated protein, wool or silk. Specified compounds capable of copolymerizing with the acrylic or methacrylic N-methylolamide, or ether thereof, are the following: esters of acrylic, methacrylic, maleic or fumaric acid, nitriles of unsaturated carboxylic acids, N-disubstituted amides of unsaturated carboxylic acids, vinyl esters such as vinyl acetate and vinyl propionate, vinyl and vinylidene halides, vinyl or vinylidene cyanide, vinyl ketones such as vinyl methyl ketone, styrene, C-vinyl pyridine, N-vinylimidazole, N-vinylpyrrolidone, N-vinylcaprolactam, N-vinyl pyridine, unsaturated aldehydes such as acrolein and methacrolein, and esters of unsaturated alcohols, such as those of allyl and methallyl alcohol. Examples are given.
