Improvements in or relating to the treatment of textile materials

Abstract

Abstract A dihydroxy-alkyl benzene is added to textile lubricants to inhibit development of acidity and mould during storage of the lubricant or fabric. 0,8--0,575 per cent of hexyl-, propyl- or butyl-resorcinol, hexyl-hydroquinone or hexyl-pyrocatechol is suitable. The composition may comprise glycerine, an oil such as olive oil, castor oil or tea-seed oil; starch, solubilized dextrine, and/or gelatine; other agents such as waxes or resins may be present. The composition may be applied direct or in solution.ALSO:Threads, yarns, fabrics, and other textile materials are sized with a composition containing a dihydroxy-alkylbenzene. The composition preferably has a starch and/or gelatine base and contains up to 1 per cent of hexyl-resorcinol. The dihydroxy-alkylbenzene preserves the size and prevents bacterial or mould action. Other suitable compounds are propyl and butyl-resorcinol, hexyl-hydroquinone and hexyl-pyrocatechol. The size may comprise starch, solubilized dextrine, and/or gelatine; also glycerine, an oil, e.g. olive oil, castor oil or tea-seed oil; other agents such as waxes or resins may be present. The size may be applied direct or in solution, by drawing yarns over rollers, wicks, discs or other means, e.g. as described in British Specifications 337,433, [Class 120 (ii)], 355,794, [Group IX], 359,477, 366,585, 390,861, 391,443. 392,904, 398,191, [all in Group IV], and 404,171, [Group IX], and in U.S.A. Specifications 1,929,192, and 1,972,924. Yarn in package form may be treated with a solution of the size; or the size may be applied to fabrics by padding mangles. In an example, cellulose acetate yarn is passed through a bath containing 4 parts of gelatine, 5 of dextrine rendered soluble in water, 2 of glycerine, 1/2 -1 of olive oil, sufficient water to make a milky solution, and ,25 per cent of hexyl-resorcinol, so that the yarn takes up 5 per cent of its weight of solid ingredients.
