Abstract
Solvent-resistant textile coatings are prepared by applying to a textile a solution of a copolymer in an organic solvent, which copolymer contains 90 to 99% by weight of an ester of acrylic acid with a monohydric alcohol having 2 to 4 carbon atoms, 0.5 to 5% by weight of 2-hydroxy-n-propyl methacrylate and 0.5 to 5% by weight of acrylic acid and/or methacrylic acid in polymerized form and which solution contains a cross-linking agent which is able to react with the hydroxyl and/or carboxylic acid groups of the polymer to form a cross-linked product, and then reacting the polymer and cross-linking agent with each other. The copolymers used are preferably prepared by copolymerizing the appropriate monomers in solution in an organic solvent below 85 DEG C. using as initiator azodiisobutyronitrile, benzoyl peroxide, lauroyl peroxide, dichlorobenzoyl peroxide, t-butyl perisobutyrate, dicyclohexyl peroxy-dicarbonate or mixtures thereof, e.g. azodiisobutyronitrile plus benzoyl peroxide. Suitable cross-linking agents include condensation products of formaldehyde with urea, thiourea, ethylene or propylene urea, aminotriazines, e.g. melamine, guanamines and ethers thereof; di- and poly-isocyanates; masked isocyanates; polymers or copolymers containing optionally etherified N - methylol - acrylamide groupings; and phenol-formaldehyde condensation products. Cross-linking is preferably completed, during or after evaporation of the solvent, at 30 DEG to 150 DEG C. When formaldehyde condensation products are used for cross-linking, a free acid such as oxalic or maleic acid may be included in the coating compositions. The compositions may be pigmented with organic pigments or inorganic pigments, e.g. kaolin, titanium dioxide, iron oxide, chromium oxide and silica.ALSO:Solvent-resistant textile coatings are prepared by applying to a textile a solution of a copolymer in an organic solvent, which copolymer contains 90 to 99% by weight of an ester of acrylic acid with a monohydric alcohol having 2 to 4 carbon atoms, 0.5 to 5% by weight of 2-hydroxy-n-propyl methacrylate and 0.5 to 5% by weight of acrylic acid and/or methacrylic acid in polymerized form and which solution contains a cross-linking agent which is able to react with the hydroxyl and/or carboxylic acid groups of the polymer to form a cross-linked product, and then reacting the polymer and cross-linking agent with each other.

Cross-linking is preferably completed, during or after evaporation of the solvent, at 30 to 150 DEG C., for example by passing the coated fabric through an optionally heated drying panel. When formaldehyde condensation products are used for cross-linking, a free acid such as oxalic acid or maleic acid may be included in the coating compositions. The compositions may be pigmented with organic pigments or inorganic pigments, e.g. kaolin, titanium dioxide, iron oxide, chromium oxide and silica. Textiles which may be treated include cotton, polyamide, polyester and polyester-cotton fabrics, which may be coated with the polymer solutions by means of a floating knife or rubber blanket coater. More than one coating may be applied, and cotton or blended cotton fabrics may be calendered before or after the first coat is applied. The treated textiles may subsequently be coated with hydrophobic agents, e.g. silicone-based impregnating agents, and those based on paraffin or perfluorocarboxylic acid/chromium complexes, or hydrophobic agents modified by masked isocyanates.
