    Abstract: The invention comprises compounds having the general formula wherein A represents a radical having one of the following formulae:- p represents one of the whole numbers 1 to 4, q represents one of the whole numbers 2 to 4, r represents one of the whole numbers 2 to 4, s represents one of the whole numbers 0, 1 or 2 and M\s3 represents an alkali metal or ammonium ion. They may be obtained by reacting a dichloride of the formula Cl-A-Cl with twice the molar amount of b -hydroxyethylmercaptan with elimination of HCl to give HO-CH2-CH2-S-A-S-CH2-CH2-OH, reacting this compound with twice the molar amount of b -chloroethanol, and esterifying the compound of the formula with H2SO4, ClSO3H or oleum and subsequently neutralizing the product with an alkali. An example is given for the preparation of the compound of the formula The products are suitable for crease-proofing textile materials containing reactive hydrogen atoms (see Division D1).ALSO:Textile materials of fibre forming substances containing reactive hydrogen atoms are finished by treating the material in any sequence with a solution of a sulphur-containing organic compound of the general formula:- wherein A represents a radical having one of the following formulae:- p represents one of the whole numbers 1 to 4, q represents one of the whole numbers 2 to 4, r represents one of the whole numbers 2 to 4, s represents one of the whole numbers 0, 1 or 2 and M\sJ represents an alkali metal or ammonium ion (see Division C2 for preparation); and with an alkaline reacting substance. Conventional crosslinking resin finishing agents and also acid or potentially acid catalysts may be used in the process-Polymer dispersions or solutions may be added to aqueous solutions of compounds of the above formula which may also contain conventional cross-linking finishing agents. Specified polymer dispersions being homopolymers and copolymers of acrylic esters or polyethylene. Specified polymer solutions are polyacrylamide solutions. Softening agents may also be added. Examples are given for the treatment of textiles with compounds of the above formula.

    Abstract: A process for desizing a fabric web comprising the steps of: first wetting the dry size-loaded fabric with the desizing liquor separated from a previous batch of fabric after desizing, so that the fabric, and the size adhering thereto, take up water from the desizing liquor by swelling and/or solvation, thereby increasing the concentration of the desizing liquor; separating the concentrated desizing liquor from the fabric; recycling the concentrated desizing liquor to a sizing operation; desizing the wetted fabric by a continuous fresh water wash; separating the desized fabric from the resulting desizing liquor; and recycling the desizing liquor to the first wetting step.

    Abstract: O.Z.0050/034040 of the disclosure: Though the recycling of sizing agents is increasingly practised, the concentration of sizing agent in the desizing liquor is insufficient for direct re-use in sizing, and hence the liquor must be strengthened. According to the invention this is achieved if the dry size-laden fabric (which may or may not have been singed) is first wetted, where relevant with simultaneous quenching, in countercurrent with the desizing liquor,i.e., size solution obtained after washing, so that the fabric and the size adhering thereto take up water from the size solution by swelling and/or solvation, thereby increasing the concentration of the size solution. This strengthened solution is subsequently separated from the fabric and recycled, whilst the fabric is only then subjected to the actual washing process to remove the sizing agent.

[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.
