Description
Dem erfindungsgeaäBen Verfahren liegt die Erkenntnis zugrunde, da8 Cellulosebestandteile allgemein und ins- besondere auch aus Geweben durch saure Behandlung abge- baut und dadurch entfernt werden können. Es ist beispiels- weise bekannt, Gewebe, die aellulosebestandteile enthal- ten, mit wässriger Schwefelsäure oder Lösungen saurer Salze, Wie Aluainiwachloridlösung, zu behandeln, zu trock- nen und anschließend in sogenannten Brennkammern auf et- wa 1000 C zu erwäraaa. Durch die eintretende saure Hydro- lyse wird die Gellulose abgebaut und kann dusch eine mechanische Nachbehandlung aus den Gewebe entfernt werden. Bei diesem Verfahren, das in der Technik unter dem Namen "Karbonisation* bekennt ist, wird das Gewebe, z. B. Wolle, das in der Hauptsache aus reitgehend säurebeständigen Fasern (%ratin) besteht, örtlich nicht vollständig zerstört, sondern bleibt auch nach Entfernung der abgebauten Cellulosebatandteile in seiner Gesamtheit-erhalten.ErfindungsgeaäBen the method is based on the recognition DA8 cellulose components in general and in particular also builds off from tissues by acid treatment and can be thereby removed. It is known, for example, to treat fabrics which contain aellulose constituents with aqueous sulfuric acid or solutions of acidic salts, such as aluminum wax chloride solution, to dry them and then to heat them in so-called combustion chambers to about 1000 ° C. By entering acidic hydro lysis, the Gellulose is degraded and can shower, a mechanical post-treatment of the tissue to be removed. In this method, which is committed in the art under the name "carbonization *, is the tissue, eg. Wool, which consists in the main of riding continuous acid-resistant fibers (% ratin), spatially not completely destroyed, but remains even after Removal of the degraded cellulose components in their entirety - preserved.
Es wurde nun gefunden, da8 'feile beliebiger Fora, wie z. B. Zuschnitteile, aus einer Textilbahn, die aus Gellu- lose besteht oder deren Zusammenhalt auf einem Gelluloseanteil beruht, leicht abgetrennt werden können, wenn die Rückseite der Textilbahn an den zu trennenden Stellen mit einer nicht fließenden Paste bedruckt wird, die die cellulose oder Gellulosebestandteile zerstört, derart, daß der Stoff an dieser Stelle auseinanderfällt oder brüchig wird. Die verhältnismäßig dicke Paste, die aus einem Gemisch aus einer sauren Verbindung, beispielswei- se konzentrierte Schwefelsäure oder Aluminiumchlorid, de- ren Anteil von 5 - 30 96 beträgt, einem Verdickungsmittel und ggf. einem Netzmittel besteht, wird vorzugsweise un- ter Verwendung einer die Konturen der abzutrennenden Teile aufweisenden Filmdruckschablone oder Gravurwalze aufgetragen bzw. aufgedruckt und bei etwa 20 - 800 C ge- trocknet, Nach dem Trocknen wird das Gewebe entweder bei Zimmertemperatur verhängt oder 1 - 10 Minuten lang auf 80 - 2000 0 erwärmt. Nach dieser Behandlung ist die Tex- tilbahn an den bedruckten Stellen zerstört oder zumindest so brüchig, daß die einzelnen Teile leicht und mühelos abgetrennt werden können. Im Gegensatz zu der mechanischen Abtrennung, die insbesondere bei einseitigen Fassrteztilien, wie Mohairplüsch, sehr zeitraubend ist, lassen sich nach dem erfindungsgemäßen Verfahren glatte Textilien sowie besonders auch die genannten Plüsche sehr schnell und sauber in viele Einzelteile trennen, wodurch die Vorarbeitung großer Materialmengen in kurzer Zeit möglich ist. Die Form der aus der Textilbahn abgetrennten Teile ist beliebig, so daß mit den entsprechenden Schablonen oder Walzen jeder gewünschte Schnitt hergestellt werden kann. It has now been found that file any fora, such as As blank parts, can be easily separated from a textile web consisting of Gellu- loose or the cohesion of which is based on a Gelluloseanteil when the back of the textile web is printed on the to be separated points with a non-flowing paste, the cellulose or Gellulosebestandteile destroyed in such a way that the fabric falls apart or becomes brittle at this point. The relatively thick paste, which de- ren proportion of 5 of a mixture of an acidic compound, beispielswei- se concentrated sulfuric acid or aluminum chloride - 96 is 30, a thickening agent and possibly a wetting agent is, preferably un- ter use of the contours of the separated parts having screen printing stencil or gravure roll coated or printed and at about 20 - dried before 800 C, After drying, the tissue is either imposed at room temperature or 1 - 10 minutes at 80-2000 0 heated. After this treatment , the textile web is destroyed at the printed areas or at least so brittle that the individual parts can be separated easily and effortlessly. Unlike mechanical separation, which is very time consuming especially in unilateral Fassrteztilien as mohair, can be prepared by the novel process smooth textiles, and especially the plushes called very quickly and cleanly separate into many pieces, so that the presowing large amounts of material in a short Time is possible. The shape of the parts separated from the textile web is arbitrary, so that any desired cut can be made with the appropriate templates or rollers.
Wesentlich ist, daß eine verhältnismäßig dicke Paste verwendet wird, die ein Fließen der sauren Verbindung verhindert, damit die Textilbahnen tatsächlich nur an den gewünschten Trennlinien durch die Hydrolyse angegrif-fen und nur die hier befindliche Gellulose zerstört wird. Als Verdickungsmittel eignet sich beispielsweise das Pflanzengummi Traganth und als Netzmittel kann Natriuadioctylsulfosuccinat verwendet werden. It is essential that a relatively thick paste is used which prevents the acidic compound from flowing, so that the textile webs are actually only attacked by the hydrolysis at the desired dividing lines and only the gelulose located here is destroyed. The vegetable gum tragacanth, for example, is suitable as a thickening agent and sodium dioctyl sulfosuccinate can be used as a wetting agent.
Die Erfindung wird im folgenden anhand einiger Ausführungsbeispiele näher erläutert. The invention is explained in more detail below with the aid of a few exemplary embodiments.

Die Teactilbahnteile weisen an den Trennlinien chemisch - also nicht mechanisch - zerstörte Fasern auf, was auch durch das bloße Auge festzustellen ist,, wie das als Muster beigefügte Stoffteil zeigt. The fabric parts have chemically - not mechanically - destroyed fibers at the dividing lines, which can also be seen with the naked eye , as the piece of fabric attached as a sample shows.
