Abstract: 1,225,275. Treating textiles. DEERING MILLIKEN RESEARCH CORP. 8 March, 1968 [10 March, 1967], No. 11430/68. Heading DIP. [Also in Division C3] Textile material is given oil and water repellency and soil release characteristics by applying thereto a soil release polymer which is a copolymer having at least 10% by weight of acidic groups calculated as acrylic acid and a fluorocarbon which is an oil and water repellent material. Suitable soil release polymers are those of acrylic, methacrylic, maleic, fumaric, itaconic, crotonic, cinnamic or a polymerizable sulhoponic or phosphoric acid which may be copolymerised with an ester of one of these acids, a vinyl halide, styrene, acrylonitrile, methyl styrene, chlorostyrene, acrylamide N- methylol acrylamide, divinyl benzene or butadiene, and the sodium, potassium, lithium and ammonium salts thereof. The textile material may also be treated with a textile resin, e.g. a methylol derivative of urea, propylene urea, ethylene urea, melamine, a carbamate, an alkylol amide, an acrylamide or methacrylamide, a diurea, a triazone, a halotriazone, a haloacetamide or a wax or a formaldehyde-acrolein condensation product, a formaldehyde-acetone condensation product, or an acetal or epoxy resin, a textile resin catalyst, e.g. magnesium chloride, zinc nitrate or fluoroborate, monoethanolamine hydrochloride, 2-amino-2-methylpropanol nitrate, an alkali metal sulphite which is converted into an alkali metal hydroxide by formaldehyde included in the steam for curing, sodium carbonate, silicate or phosphate, potassium bicarbonate, carbonate or phosphate, barium carbonate and lauryl trimethyl ammonium hydroxide or carbonate, a wetting agent, an emulsifying agent or softener. The reagents may be applied separately or simultaneously to the textile material from solution by padding or spraying. Fabric may be treated (1) by applying thereto a textile resin having one type of functional group, a textile resin catalyst, a soil release polymer and a water repellent drying it at a temperature insufficient to initiate catalysis of the textile resin, making it into a garment, e.g. trousers, pressing the garment to produce creases where desired, e.g. on a Hoffman press, and heating it to effect curing, (2) by applying thereto a textile resin having more than one type of functional group, textile resin catalysts for each type functional group, a soil release polymer and a water repellent, subjecting it to conditions such that one type of functional group reacts and the remaining functional groups remain dormant, making it into a garment, pressing creases in the garment and subjecting it to conditions such that the remaining functional groups react or (3) applying thereto a textile resin having more than one type of functional group, one type being sites of ethylenic unsaturation, a textile resin catalyst, a soil release polymer and a water repellent, drying it at a temperature such that the textile resin catalyst remains dormant, subjecting it to irradiation, making it into a garment, producing desired creases in the garment and subjecting it to textile resin curing conditions. Alternatively the final curing may be effected prior to garment manufacture. Fibres, yarns, threads or fabrics comprising cotton, viscose rayon, polyester, polyamide, acrylic, cellulose actate or polypropylene fibres may be treated.
