Title: New and improved compositions adapted for water-repellency treatment of textile fibre
IPC: D06M13/402
Filed: 1945-11-14
Abstract: A composition for the water-repelling treatment of textile fibre, comprises an intimate mixture of a methylene-bis-amide of an aliphatic carboxylic acid containing not less than ten carbon atoms which is free from water-solubilising groups and a dispersing agent, said agent being present in from 10 to 40 per cent by weight of the bis-amide and being a compound capable of decomposing when heated between 100 DEG  and 185 DEG  C. with formation of water-soluble, water-repellent reaction products, the whole composition being dispersible in water to yield an aqueous suspension of the bis-amide. The dispersing agent may have the formula A-CH2-Z, where A represents an organic radical free from water-solubilising groups, containing an alkyl radical saturated or unsaturated, having a straight chain of at least 7 carbon atoms, and being attached to the CH2 group through the agency of an oxygen sulphur or nitrogen atom while Z is a water-solubilising radical, that is an organic or inorganic radical containing water-solubilising groups and is attached to the CH2 group through a non-carbonic atom.  The bis-amide may be methylene-distearamide and the dispersing agent stearamido-methyl pyridinium chloride, stearamidomethyl-gamma- or octadecyloxy, methyl - pyridinium chloride.  The composition may be prepared as a paste by the aid of water-soluble organic liquids such as pyridine, methyl ethyl ketone, or lower alcohols especially isopropyl alcohol. Additional substances such as ammonium sulphocyanate, disphosphate, linseed oil, chinawood oil, polydivinylnatylene, alkyd resins, urea-formaldehyde resin, urea-formaldehyde isobutyl ether resin, shellac, butyl methacrylate-isoprene copolymer phenol-formaldehyde resin, melamine resin and a combination of urea-formaldehyde and soya bean protein formaldehyde condensation product, may be present. Specifications 466,817, 475,170 and 501,480 are referred to.ALSO:A composition for the water-repellency treatment of textile fibre, comprises an intimate mixture of a methylene-bis-amide of an aliphatic carboxylic acid containing not less than ten carbon atoms which is free from water-solubilizing groups and a dispersing agent, said agent being present in from 10 to 40 per cent by weight of the bis-amide and being a compound capable of decomposing when heated between 100 DEG  and 185 DEG  C. with formation of water-insoluble, water-repellent reaction products, the whole composition being dispersible in water to yield an aqueous suspension of the bis-amide.
