Description
Verfahren zum Färben von Holz. Die Erfindung bezieht sich auf ein Verfahren zum Färben von Holz oder anderem faserigen Material durch die ganze Masse hindurch.Method of staining wood. The invention relates to a Method of coloring wood or other fibrous material through the whole mass through.
Bisher sind Verfahren bekanntgeworden, die dem Holz nach möglichst vollkommener Trocknung durch seine ganze Masse hindurch die gewünschte Farbe mitteilen, indem diese Farbe unter Druck in das Holz gepreßt wird. Es hat sich aber herausgestellt, daß das nach diesem bekannten Verfahren gefärbte Holz versagt, wenn man es nach dem Färben einem allseitig wirkenden Druck unterwirft.So far, processes have become known that are as close as possible to the wood communicate the desired color through its entire mass when it is completely dry, by pressing this paint into the wood under pressure. But it turned out that the wood stained by this known process fails if you look at it subjected to dyeing to an all-round pressure.
Ferner ist ein Verfahren bekanntgeworden, das die durchgehende Färbung des Holzes durch aufeinanderfolgende Behandlung mit basischen und sauren Farbstoffen erzielt. Demgegenüber ist das neue Verfahren dadurch gekennzeichnet, daß das Holz nach der Trocknung in eine Farbstofflösung, bestehend aus einem Lösungsmittel wie Wasser, Spiritus o. dgl., unter Druck eingetaucht wird, worin ein saurer und ein basischer Farbstoff in einem solchen Verhältnis gelöst worden sind, daß der saure Farbstoff in Überschuß zugegen ist.Furthermore, a method has become known that the continuous coloring of the wood by successive treatment with basic and acidic dyes achieved. In contrast, the new method is characterized in that the wood after drying in a dye solution consisting of a solvent such as Water, alcohol or the like, is immersed under pressure, in which an acidic and a basic dye have been dissolved in such a ratio that the acidic Dye is present in excess.
Das Verfahren gemäß der Erfindung ermöglicht es, den Farbstoff derartig einzubringen, daß das Holz und anderes faseriges Material durch seine ganze Masse hindurch genau die gleiche Farbe beibehält, auch nachdem es dem sogenannten »Veredelungsverfahren« unterwor fen worden ist.The method according to the invention enables the dye to be so bring in that the wood and other fibrous material through its whole mass retains exactly the same color throughout, even after the so-called "finishing process" has been subjected.
Die Erfindung besteht darin, daß das Holz oder anderes faseriges Material, nachdem es getrocknet worden ist, in eine Farbstofflösung, welche aus einer Mischung eines sauren Farbstoffes und eines basischen Farbstoffes, gelöst in einem Mittel wie Wasser, Spiritus oder einem anderen Lösungsmittel zusammengesetzt ist, und zwar in einem derartigen Verhältnis, daß ein Überschuß des sauren Farbstoffes zugegen ist, getaucht wird Die Menge des Überschusses ist abhängig von der Art des Holzes oder des anderen faserigen Materials, welches gefärbt werden muß. Nach der Erfindung erhält man regelmäßig die besten Resultate mit einer Mischung, worin die Menge des sauren Farbstoffes zu der Menge des basischen Farbstoffes sich verhält wie 3 : z. Die Farbstoffe werden z. B. in eine Menge Wasser im Verhältnis von z Teil Farbstoff zu q.o Teilen Wasser gelöst. Nach Eintauchen in diese Mischung wird das Holz oder das faserige Material, vorzugsweise bei normaler Temperatur, einem Druck von roo bis 15o Atm. ausgesetzt. Bei dem nachfolgenden Pressen nach dem Holzveredelungsverfahren stellt sich heraus, daß der Farbstoff sich innig in den Zellen festgesetzt hat, so daß das Holz durch die ganze Masse hindurch eine vollständig gleiche Farbe, in Übereinstimmung mit den verwendeten Farbstoffen, bleibend behält.The invention consists in that the wood or other fibrous material, after it has been dried, in a dye solution which is a mixture an acidic dye and a basic dye dissolved in an agent like water, alcohol or another solvent is composed, namely in such a ratio that an excess of the acidic dye is present is, is dipped The amount of excess depends on the type of wood or the other fibrous material which must be colored. According to the invention the best results are regularly obtained with a mixture in which the amount of acidic dye to the amount of basic dye is related to 3: z. The dyes are z. B. in an amount of water in the ratio of z part of dye dissolved to q.o parts of water. After immersion in this mixture, the wood or the fibrous material, preferably at normal temperature, a pressure of roo up to 15o atm. exposed. In the subsequent pressing according to the wood finishing process it turns out that the dye has firmly established itself in the cells, so that the wood is completely one through the whole mass same Retains color in accordance with the dyes used.
