Process for coloring wood, horn, bone, ivory and similar fabrics.

Patented in the German Empire on June 22, 1880.

The dyeing process which forms the subject of the present patent has the Purpose, on wood, horn, ivory, bone and the like. To apply such dyes respectively. to fix, which is usually used in the dyeing of wool, cotton, silk, etc., also to apply animal, vegetable and mineral mordants. this happens with the aid of an entirely new process, the essence of which consists in the fact that many colors are used and nuances of the most varied kinds can be fixed in a single bath without doing so the individual colors flow together. The procedure is mainly about this intended to imitate the grain of precious woods on wood of inferior quality.

Very beautiful effects can be achieved on ivory, horn, bone, and the like that can be increased by varnishing and dusting.

The procedure itself is as follows:

One stirs with any kind of flour, grain flour, wheat flour, corn flour, potato flour, Chestnut flour etc. make a thin dough and spread it on a sheet of paper or Cardboard lid, on a thin sheet or the like. In a thickness of one or several millimeters the end. On this layer the paint in the form of powder or in liquid, is appropriate thickened condition, as it is used for the production of colored paper and for printing Woven fabrics used, applied and then the whole thing with the colored side on the one to be dyed Object placed. In order to achieve a complete contact of all parts, one lays it is best to put a perforated sheet behind the paper and cardboard sheets and connect them All through belts or with the help of a suitable press.

The whole thing is then immersed in boiling water or placed in a steam chamber. There the dyes dissolve and lie on the surface of the object, but at the same time the dough is cooked, it hardens or solidifies and then holds the Colors, on which it serves as a base, in their place, so that colors lying next to one another cannot run into each other.

This isolation of the coloring matter with the aid of a dough or some other, playing the same role Mass forms the essence of the present invention.

The coloring is completed in a shorter or longer time, depending on the hardness of the wood.

With harder wood, it is advisable to keep the colors more apart than with softer, because since the latter requires a longer time for the impregnation, so the colors could run into each other through the dough.

It can take several hours to achieve the desired color; where it is however, as in most cases, only a superficial coloring is sufficient half an hour.

When the coloring is complete, the dough is washed off with plenty of water and the colored one is drained Dry the surface in the shade, whereupon it can be dusted and varnished.

After dusting, you have to wipe the surface well, because if paint dust remains, the alcohol in the paint would dissolve the color of this dust, creating stains.

Do you want. Produce grains, the colors are turned in sufficiently thickened ones Solutions of rubber, dextrin, etc. These colors are then used in certain Place the dough in more or less thick drops in the direction of the one to be produced Grain applied and spread out with the help of bellows. Then proceed, ■ as described above.

• The color which forms the grain can also be applied directly with the aid of a brush, in which case only the base color is applied to the dough.

The paint to be applied with the brush must be carried out with the help of some material, e.g. B. rubber, be quite thickly thickened.

In certain cases, like ζ. B. when applied bouquets of flowers or other ornaments you can first apply the insulating compound in a thin layer. Should z. B. Flowers are painted on wood, so you cover the wooden surface first an albumin layer and then paints the flowers on this with the help of a brush or applies them with the help of the colored pencils to be described below and then sets them the action of hot water or steam. The colors penetrate the wood while the albumin coagulates under the action of heat and the colors increase holds their place.

To achieve the most varied of effects, you can also use the colors to be applied Soak up sawdust or another indifferent powder and mix it with the Sprinkle strongly impregnated powder on the dough in the manner described above, which one then applies to the surface to be colored. Under the influence of moisture and The sawdust gives off some of the dye, which then spreads to the the area to be colored. This process is less costly than doing the paint in powder form for itself and directly.

To fix certain colors, stain is applied beforehand, e.g. B. alum, acetic clay, Chrome alum, tin salts and other substances used in dyeing on the to be painted Area.

As for the colors, in the present process one can do all of them in the dye factory use used.

You can also use metal salts in the present process, which by double decomposition results in insoluble, colored precipitates. These salts are applied to the Dough applied and then brought with this on the surface to be colored. Under action of a suitable reactant then forms colored precipitates, which enter the wood penetration. In this way the wood is colored and preserved at the same time.

As the dough isolates the salts, it is understandable that several salts can be applied at the same time and in this way receives several colors at the same time, whereby the Reactiv is common to all is and forms the color bath.

One can proceed in such a way that, with the aid of the dough, one can begin with the way described applies the salts as if one were dealing with definitive colors; after the dough and the excess salts have been removed, one immerses the wooden surface in the reactive, whereupon the different colors appear in their place, according to the difference in the salts used and the nature of the Metal bases.

In order to promote the penetration of the colors, one can also use a vacuum or use steam which, after opening the pores of the wood, condenses.

One can also specialize in making fine fibers, flowers and foliage use prepared colored pencils.

To make these pencils, the colors are mixed in powder form with talc, kaolin or another indifferent substance depending on the color shade to be achieved. That The mixture is then mixed with some kind of binding agent (rubber solution, etc.) to a pulp, shaped into sticks and left to dry.

You can also add stain to the mass from which the pencils are made, if the wood to be colored has not already been impregnated with such stains. Finally, the pens can also contain some hygroscopic substance, so if so the surface to be colored is exposed to the action of steam, this substance is the condensation water absorbed and causes a solution of the admixed soluble substances.

The colored drawings that were applied to the object with these pens, are treated with hot water or steam with the aid of the starchy flour-containing, dough containing albumin, etc., is fixed.

The process is mainly used to imitate foreign woods, but it can be explained how noted, can also be used with advantage for other purposes.

Applied to wood it offers the great advantage that the texture of the wood does not is hidden, as is the case with ordinary dyeing. There is also the color if a layer does not form on the wood, it can be polished without disadvantage, as other woods.

Claims (1)

Patent claim: One process, wood, ivory, bone and similar substances simultaneously with different To color colors, consisting in one of the different colors with the help of one soft dough that hardens or solidifies under the action of heat, which they are brought onto the surface to be colored and kept isolated from one another.
