    • Etched or burned out patterns are produced on fabrics consisting of nylon yarns and either rayon yarns or yarns of vegetable or animal origin by removing one kind of yarn by solvents or degrading agents, the other yarn being unattacked. The yarn woven with the nylon may be cotton, wool, silk, regenerated cellulose or a cellulose derivative. For the selective removal of portions of natural or regenerated cellulose yarns reagents such as calcium thiocyanate, cuprammonium hydroxide, certain quaternary ammonium compounds such as dibenzyl dimethyl ammonium hydroxide, zinc chloride, zinc-hydrochloric acid mixtures, sulphuric acid, hydrochloric acid, phosphoric acid, aluminium chloride, aluminium sulphate, magnesium chloride and other hydrochloric acid-liberating salts may be employed. Cellulose derivative yarns are removed by suitable solvents such as acetone for cellulose acetate. Silk or wool may be removed with strong alkalis (NaOH, KOH). Prolonged contact of the nylon with strong mineral acids and caustic alkalis should be avoided. Nylon may be removed by the action of phenol or concentrated formic or acetic acid. The fibre-removing agent may be printed directly on to the fabric, or the fabric may be printed with a suitable resist and then impregnated with the reagent. In examples: (a) a fabric of nylon yarns and cellulose yarns is printed with a paste of aluminium sulphate and dextrine, heated to 248 DEG F. for 10-20 minutes and the carbonized portions removed by rubbing, brushing and/or soaping; (b) a fabric of nylon and cellulosic yarns is printed with a paste comprising thickened sulphuric acid, heated to 210 DEG F. for 15-20 minutes and treated as in (a); (c) a fabric of nylon yarns and cellulosic yarns is printed with a phenol-dextrine paste, heated to 100 DEG F. for 10-20 minutes to swell and dissolve the nylon in the printed areas, the solubilized yarn portions removed by suction and the fabric washed.

    • 182,756. Sayles Finishing Plants, Inc., (Assignees of Huey, H. I.). July 7, 1921, [Convention date]. Resist printing.-Woven, knitted, felted, or paper webs for use, for example, as linings for cuffs, collars, &c., are so treated as to be made permanently stiff, by metamorphosis of the component fibres, except in predetermined bands or lines 2, where the web remains in its original flexible state so as to facilitate folding. The web may be stiffened in the desired places 1 by means of a parchmentizing-agent, such as sulphuric, hydrochloric, nitric, or phosphoric acid, or a mixture of these acids, or by means of cuprous oxide or zinc chloride. The acid &c. may be printed on the web, leaving the portions 2 untouched; or these portions may be previously printed with a resist. The flexible portions 2 of the web &c. may be coloured so as to contrast with the stiffened portions and thus be rendered easily discernible. The narrow bands &c. 2 also constitute guides, which may be used in cutting- out the web. The web may be mercerized. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of " converted starch " as a resist. This subject-matter does not appear in the Specification as accepted.
