244,979. British Celanese, Ltd., Ryley, C. F., and Awcock, G. R. June 27, 1924. Sizes.-Sizing preparations for yarns or threads, particularly those of silk, spun silk, or artificial silk, comprise one or more lubricating agents, namely, non-drying oils, fats, waxes, or liquid or solid fatty acids, together with one or more resins, as dammar resin or gum mastic. One or more soaps of fatty acids, including those of sodium, potassium, ammonium, but preferably those of calcium, magnesium, zinc or aluminium, may be added. The resin may be dissolved in benzol, toluol, xylol, oil of turpentine, &c., with admixture of the lubricating agent; or emulsifying agents may be used; or the materials may be melted together. The following is given as an example : Gum mastic or dammar resin 20 parts by weight, lard 7 parts, xylene 25 parts, with or without magnesium oleate 1¢ parts. The preparation may be applied by dipping the yarn in hanks, or during winding of the yarn; or it may be applied to artificial threads of cellulose esters or ethers continuously with their production by the dry or evaporative spinning method, as described in Specification 210,266, [Class 120 (iii), Yarns &c.]. The size may be removed by scouring with a soap solution, with or without previous treatment with acid.
