Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed March 24, 1908, Serial No. 485,511.

To all whomit may concern:

Be it known that I, MAX Bnoxn, a citizen of the Empire of Germany, residing g'ated, marbled or veined in two or more dif- I ferent colors, or which show relief-like colorefiects resembling natural patterns or regularly arranged figures with a coloring having a relief-like effect, and the like. At first it seemed impossible to apply these eculiar color effects also to textile goods, because the latter do not at all possess the property by which alone the manufacture of such colored papers is practicable, namely that the particles of the material are capable of being shifted. I have now found that the production of the said peculiar colorefiects on textile fabrics of every kind is nevertheless practicable, if the paper-web while being formed is utilized as a preliminary means for producing the coloration and the coloration thus produced on the paper-web is transmitted to the textile fabrics by bringing the colored paper-web into temporary contact with the textile fabric to be colored. In this manner it is possible to produce all the peculiar color-effects which can be produced on paper while it is being made also on textile fabrics of all kinds, such as cotton-, wool-, silk-, linen-, jute-, ramie-, artificial silkhalf-woolen-, half-silk-, wool-silk-fabrics, as well as on velvets, peluches, astrakhans, felts and the like.

For producing the color-effects, almost all the methods which are practiced in the textile industry may be used, namely in such a manner that the color-changing substances which are to be used for producing the desired color-effects are applied to the paper-web to be utilized for the preliminary producing of the color-effect. The colorat1on may be made on the paper-web by the appllcatlon of dyestuffs, resists, discharges, dye-components, mordants or by any other color-changing agents or means for changmg the absorbability of the fibers for dyestuffs, whereas the textile fabrics, which are to receive the coloration from the paperweb, are usedin an uncolored, colored, mordanted, naphtholized, etc., state. If the prelimmary production of the coloration is effected by mordants, resists, discharges or similar colorless or slightly colored solutlons, suitable coloring matters are added to them in the usual manner, in order to be able to observe and arrange the coloration.

For the preliminary production of the coloration any method by which the paperweb while being formed can be partly stained may be used. For instance the following methodsmay be mentioned:

(1) Paper-pulps of different color are thrown on the paper-web while being formed by means of ladle-shaped arms fitted to a revolving shaft. Thereby a flaky marbling in two or more colors is produced, which by bringing the paper-web into contact with any textile fabric is transferred to the latter. Similar marblings, but of a more uniform appearance, are produced by running paper-pulps of a different color on the paper-web while being formed, by means of an inclined plane.

(2) Diiferently-colored paper-fibers are brought together in the pulping-machine or in the color-trough and then put together on the endless wire. If the coloring is effected by means of suitable, transmissible dyestuifs, and if the paper-web which is forming and which shows a uniformly mixed coloration is brought into contact with a textile fabric, there will be produced on the latter the exact picture of the mixed coloration.

(3) Dye-solutions (or mordants, discharges, resists, etc., for colorings of various kinds) are caused to run, either directly or by means of absorbent felts or the like, into that part of the paper-web being formed which is in front of the skimmingboards. By natural or mechanical movements of the paper-web or of the dyestufftransmitter, veins of different color are formed in the paper-pulp, which by being brought into contact with a textile fabric are transmitted to the latter. Instead 'of the dye-solutions, fibers of different color may be introduced into the web part of the paper-web in front of the skimming-boards, whereby veinings of a different kind are produced.

(4) Felts or similar fabrics which are soaked with dye-solutions (or mordants, discharges, resists, etc.) are caused to trail on a paper-web while being formed. These trailing pieces only dye those parts of the surface which are up ermost and which'are opposite to the direction of the movement of the paper-web, whereby a uniform marbling is produced. The application of the color may be effected not only by means of trailing fabrics but also by means of nozzles by which the coloring-matter is sprayed on the paper-web at a very acute angle. Thereby colorations of relieflike effect are produced.

(5) If the dye-solutions are thrown in a curve from above, by means of spraying nozzles, onto the paper-web where it contains less water, dotted colorations and areolas of peculiar effect resemblincg syenite, granite and porphyry are produce If the paper-webs colored in any of the above described manners are brought into contact with colored or uncolored textile fabrics, the coloration-effect produced on the paper is exactly transmitted to the fabric.

(6) The still wet paper-web while being formed is slightly im ressed with fabrics, metallic tissues, relie ike embossed cylinders, suitably engraved plates, etc, and then dye-solutions (or solutions of mordants, resists, discharges, dye-stuff compositions and the like) are sprayed at an acute angle on the paper web provided with the engraved atterns. By transmitting the coloration-e ect of the paperweb to textile fabrics, patterns are obtained of a peculiar plastic effect such as cannot be produced-even not similarly by the means hitherto used in cottonwool-, etc., printing.

The transmission of the preliminary coloration, produced on the aper-web, to the textile fabrics can be e ected in various ways. In many cases it will suffice to pass the fabric to be dyed together with the paper-web, immediately after the latter has been colored, through one or several pressing-rollers (for instance through the couchroll or the presses of the engine). The procedure may also be as follows: The paper is first finished and only then it is brought into contact (preferably in a Wet condition) with the fabric to be colored. The transfer of the coloration from the paper-roll to the fabricroll may be effected by means of pressing-rollers or circular presses, or by placing the fabric and the paper in layers one upon the other in presses (like the Spahn press) and pressing for a shorter or longer time. Further the paper-web and the fabric may be wound up together on solid or perforated cylinders and thus the transmission of the coloration effected. The transmission of the coloration may be facilitated, that is to say, modified, by moistening or damping, application of heat and steam.

The finishing of the colorations on the textile fabrics is carried out in an appropriate manner according to the nature of the dyestuffs used, 2'. e. by simply drying, or by steaming, fixing, coupling, etc.

One apparatus for carrying out the process is shown in the accompanying drawin in which the figure is a side elevation, partly in section.

In this apparatus paper-pulp flows from a tank 1 beneath s imming-boards onto a wire-cloth belt 2, thereby forming'a paperweb 3. A liquid coloring a cut contained in a vessel 5 is delivered in rops or regu lated amounts, through one or more cocks 5, onto the pulp or incipient paper-web behind the last skimming-board 4:. The wirecloth carrying the paper-web thence passes over the suct1on-boxes 6, for removing water, and beneath the engraved or embossed roller 7, which impresses its pattern upon the soft web. Additional color may then be s rayed u on the web from a transverse per orated pipe 8. The textile fabric to which the color-effects are to be transferred is unwound from a-roll 9 and carried beneath the wet-press roller 10, whereby it is brought into intimate contact with the colored web. Emerging from beneath this roller, the colored fabric is again separated from the web and is rewound upon a roll 11. The colored web 3 thence passes onto a felt belt 12. Other fabric to be colored is unwound from a roll 13 and is pressed into contact with the colored web by the couchroller 14, being then rewound upon the roll 15. The paper-web is delivered to the usual driers. If color is sprayed from the pipe 8 at a very acute angle to the paper-web, relief-color effects are obtained on the finished fabric. Most varied effects are obtained by employing the roller 7 and making figured impressions in the web before spraying on the color.

While the machine illustrated is a suitable and effective one, it will be understood that the process may be carried out by a variet of mechanisms, provided that the color e fects be first produced on a paper-web and my invention and in what manner the same is to be performed,
