Abstract

543,125. Artificial filaments, films &c. resinous condensation &c. products ; treating textiles with liquids. DU PONT DE NEMOURS & CO., E. I. Aug. 5, 1940, No. 12582. Convention date, Aug. 4, 1939. [Classes 2 (ii), 2 (iii) and 15 (ii)] A. synthetic linear polyamide article in the form of a filament, pellicle, or the like is subjected to treatment with an acidic material until the tenacity is reduced by at least 2 per cent. but not more than 40 per cent. in order to obtain a reduction in lustre and to increase the surface friction. In the case of fibres the abilitv to recover from elastic stretch and the elongation properties are increased. Knitted fabrics are given a greater resistance to slipping or laddering. The polyamides used may be obtained from monoaminocarboxylic acids or their amide-forming derivatives or from diamines and dibasic carboxylic acids or their amide-forming derivatives. The acidic substance may be titanium tetrachloride, phosphorus tribromide, sulphur monochloride, thionyl chloride, sulphuric acid, hydrochloric acid, pyrosulphuryl chloride, sulphuryl chloride, chloracetyl chloride, phosphorus trichloride, or sulphamic acid. The polyamide article may be in the form of a yarn, fabric, film, bristle, sheet, or massive moulded form. In an example, yarn spun from molten polyhexamethylene adipamide is cold drawn and then passed through a solution of sulphuryl chloride in petroleum ether and then through a solution of aqueous ammonia and methanol. In other examples, yarns, fabrics, or films are treated with chloracetyl chloride in carbon tetrachloride, phosphorus trichloride in carbon tetrachloride. sulphamic acid in water, or sulphuryl chloride in petroleum ether. Yarns already delustred with titanium oxide may be subjected to the treatment. Dyed fabrics may be treated. The polyamide articles may contain plasticizers, pigments, dyes, de-lusterants, anti-oxidants, oils. and resins. The treatment may be effected at low or high temperature or pressure, and the materials may be under tension. The treatment improves the adhesion of sizes, finishes, sub-coats, or adhesives to the materials particularly films and sheets. The process may be applied to wire coated with polyamide. Instead of using simple polyamides, the articles may be made of interpolyamides or of polyamides containing ester groups, e.g. a polyamide from adipic acid, hexamethylenediamine and ethylene- or hexamethylene-glycol. Specification 461,236 is referred to. Reference has been directed by the Comptroller to Specifications 530,833, 532,674, 534,698 and 535,379.
