Abstract: 6876. Farbwerke vorm. Meister, Lucius, & Br³ning. March 27, 1908, [Convention date]. Printing fabrics; printing-surfaces; transferring designs and the like; transfers.-Textile fabrics of any kind are given marbled, or variegated, or veined colour effects, in two or more colours, or relief - like colour - effects resembling natural patterns, or regularly-arranged figures with a colouring having a relief-like effect, by transference from a paper-web suitably treated with the necessary agents, such as dyes, resists, discharges, dye-components, mordants, &c., the application of all such substances being understood to be covered by the expressions "coloration," &c., below. The fabrics to be treated, which may be uncoloured or previously coloured, mordanted, naphtholized, &c., comprise fabrics of cotton, jute, linen, ramie, silk, artificial silk, wool, half-silk, half-wool, or woolsilk, and astrachans, felts, plushes, velvets, &c. The fabric to be dyed is passed with the paperweb, immediately after the latter has been coloured, through one or more pairs of squeezerollers, for example through the couch roll or the presses of the paper-making machine. Or the paper is finished and then brought into contact, preferably wet, with the fabric, the coloration &c. being transferred by pressure rollers or by superposing the fabric and the paper in layers in presses, such as the " Spahn " press. Or the paper-web and the fabric may be wound up together on solid or perforated cylinders to effect the transference. The transference may be facilitated, or modified, by moistening or applying heat and steam. Suitable finishing is effected, such as drying or steaming, fixing, coupling, &c. The coloration &c. of the paper-web may be produced in several ways, as follows : (1) By throwing paper-pulp, of a different colour from that of the main supply, on to the web, while it is being formed, by means of revolving ladle-shaped arms ; in this way flaky marbling in two or more colours is produced. (2) By running the second pulp down an inclined plane on to the web, giving similar but more uniform marblings. (3) By bringing differently coloured paper-fibres together in the pulping- machine and then charging on to the wire-cloth. (4) By running the dye-solutions, mordants, discharges, resists, &c., directly, or with the aid of absorbent felts &c., into that part of the paperweb being formed in front of the sluices. (5) By introducing differently-coloured fibres in place of the solutions, as in (4), different veinings being obtained. (6) By causing felts &c., soaked with dye-solutions &c., to trail on the web during formation, giving a uniform marbling. (7) By spraying the colouring-matter from nozzles at a very acute angle to the web, giving relief-like colorations. (8) By spraying, in a sweep from above, on to somewhat dry paper-web, giving peculiar dotted colorations. (9) By spraying, as in (7), after slightly impressing the wet web with fabrics, metallic tissues, relief-like embossed cylinders, engraved plates, &c. ; this gives patterns of a "peculiar plastic effect" on the subsequently-treated fabric.
