Patentiert im Deutschen Reich vom 22. Oktober 1941 an Patenterteilung bekanntgemacht am 1. Februar 1945Patented in the German Reich on October 22, 1941 Patent granted February 1, 1945
Es ist bereits bekannt, Textilgut aus pflanzlichen Fasern mit Cellulosehydrat unter Verwendung von Viskoselösungen oder Kupferoxydammoniakcelluloselösungen zu appretieren.It is already known to use textiles made from vegetable fibers with cellulose hydrate of viscose solutions or copper oxide ammonia cellulose solutions.
Diese so erhaltenen Appreturen sind jedoch mit dem Nachteil behaftet, daß ihre Festigkeit zu wünschen übrigläßt und sie der Ware eine gewisse Härte verleihen.These finishes thus obtained, however, have the disadvantage that their strength leaves a lot to be desired and gives the goods a certain hardness.
Man hat versucht, den Nachteil hinsichtlich des Griffes der Ware durch Anwendung verdünnterer Celluloselösungen oder verschäumter Celluloselösungen zu beheben, womit jedoch die Festigkeits- und Haftverhältnisse der Appretur verschlechtert wurden. Weiterhin hat man versucht, die hart machende Wirkung der Appretur bzw. deren Haftfestigkeit durch eine Behandlung des Textilgutes vor oder nach dem Aufbringen des Cellulosehydrats mit schrumpfenden Mitteln, wie Säuren oder Laugen, zu beheben. Die Behandlung der Gewebe mit Säuren kann jedoch nur bei Verwendung von kostspieligen säurefesten Apparaturen erfolgen. Aber auch in diesem Fall läßt es sich schwer vermeiden, daß Eisen- oder andere Metallflecke im Gewebe entstehen. Auch beeinträchtigt die Säure bei einer zur Schrumpfung genügenden Konzentration die Zerreißfestigkeit des Fasergutes. Die Verwendung von alkalischen Flüssigkeiten bei dem bekannten Verfahren bewirkt hingegen den Nachteil, daß das Gut in der Breite wesentlichAttempts have been made to overcome the disadvantage with regard to the handle of the goods by using more dilute To fix cellulose solutions or foamed cellulose solutions, with which, however, the Strength and adhesion ratios of the finish were worsened. Furthermore, attempts have been made the hardening effect of the finish or its adhesive strength through a treatment of the textile material before or after the application of the cellulose hydrate with shrinking agents, such as acids or alkalis. However, the treatment of the tissue with acids can only be costly when using acid-proof equipment. But even in this case it is difficult to avoid that Iron or other metal stains appear in the fabric. Also the acid affects at a concentration sufficient to shrink the tensile strength of the fiber material. the Use of alkaline liquids in the known method, however, causes the Disadvantage that the width of the goods is substantial
eingeht. Ferner führt die nachträgliche Schrumpfung bedruckter oder mehrfarbig gewebter Waren leicht zu Verzerrungen im Muster. Alle bekannten Appretierverfahren mittels Cellulosexanthogenatlösungen sind aber überdies mit dem Nachteil behaftet, daß bei Rückbildung der Cellulose einerseits Schwefelwasserstoff entweicht, der aus den Arbeitsräumen durch kostspielige Ventilationsanlagen entfernt werdencomes in. Furthermore, the subsequent shrinkage of printed or multi-colored woven fabrics leads to Were easy to distort the pattern. All known finishing processes using Cellulose xanthate solutions, however, also have the disadvantage that when they regress the cellulose on the one hand escapes hydrogen sulfide, which escapes from the work rooms expensive ventilation systems are removed
ίο muß, und andererseits am Textilgut eine Schwefelausscheidung erfolgt, welche die Farbe der zu appretierenden Ware beeinträchtigen kann und deshalb durch Nachbehandlung entfernt werden muß. Die obenerwähnte Herabsetzung der Viskosität der Celluloselösungen ist zwar zweckdienlich, soweit es sich um die Verminderung der Steilheit und des störenden Glanzes der Appretur handelt, doch schafft sie keine Abhilfe für die mangelhafte Haftfestigkeit der Appretur. Es wurde nun gefunden, daß alle vorstehend angegebenen Nachteile nicht auftreten, wenn man zum Appretieren von Cellulosetextilgut mit Cellulosehydrat Viskoselösungen und ferner hierbei solche Fällbäder verwendet, die mit einem Oxydationsmittel wie z. B. Alkalinitrit versetzt sind.ίο must, and on the other hand a sulfur excretion on the textile material takes place, which can affect the color of the goods to be finished and are therefore removed by post-treatment got to. The above-mentioned reduction in the viscosity of the cellulose solutions is useful, as far as the reduction of the steepness and the disturbing gloss of the finish is concerned acts, but it does not remedy the poor adhesive strength of the finish. It it has now been found that none of the disadvantages indicated above do not occur when one for finishing cellulose textiles with cellulose hydrate viscose solutions and further in this case, such precipitation baths are used, which are treated with an oxidizing agent such. B. Alkaline Nitrite are offset.
Offenbar beruht die vorteilhafte Wirkung dieser Verfahrensweise auf einer Hintanhaltung einer Gasentwicklung beim Abscheiden des Cellulosehydrats auf der zu appretierenden Ware.Apparently, the advantageous effect of this procedure is based on restraint gas development when the cellulose hydrate is deposited on the surface to be finished Were.
Als Oxydationsmittel können Alkalimetallchromate oder Chlorate verwendet werden. Die besten Ergebnisse werden jedoch mit Nitriten,Alkali metal chromates or chlorates can be used as oxidizing agents. the however, best results are achieved with nitrites,
z. B. Natriumnitrit, erzielt.z. B. sodium nitrite achieved.
Es genügt, wenn das Fällbad je Liter 1 g Natriumnitrit enthält; doch muß darauf geachtet werden, daß der Nitritgehalt des Bades bei der Fällung nicht unter 0,6 g/l sinkt.It is sufficient if the precipitation bath contains 1 g of sodium nitrite per liter; but care must be taken ensure that the nitrite content of the bath does not fall below 0.6 g / l during precipitation.
Das Fällbad selbst kann beispielsweise sich aus 60 Gewichtsteilen Wasser, 20 Gewichtsteilen Glaubersalz und 20 Gewichtsteilen Schwefelsäure von 66 Be° zusammensetzen.The precipitation bath itself can consist, for example, of 60 parts by weight of water, 20 parts by weight of Glauber's salt and 20 parts by weight Compose sulfuric acid of 66 Be °.
Diesem Bad wird erfindungsgemäß noch je Liter 1 g Natriumnitrit zugesetzt.According to the invention, 1 g of sodium nitrite per liter is added to this bath.
Der bei dem Fällprozeß frei werdende Schwefelwasserstoff und Schwefel wird durch das Natriumnitrit zu leicht löslichen Verbindungen oxydiert; auch wird dabei frei werdendes Schwefeldioxyd zu Schwefeltrioxyd weiteroxydiert. Die bei dem Fällprozeß gebildete Menge Kohlendioxyd ist so gering, daß sie in Lösung geht und nicht stört. Es kommt somit praktisch gar keine Gasentwicklung mehr zustande. The hydrogen sulfide and sulfur released during the precipitation process are replaced by the Sodium nitrite oxidizes to easily soluble compounds; also what becomes free Sulfur dioxide further oxidized to sulfur trioxide. The one formed in the precipitation process The amount of carbon dioxide is so small that it goes into solution and does not interfere. So it comes practically no gas evolution occurs.
Erflndungsgemäß können sowohl lose als auch zu Garn oder Gewebe verarbeitete Fasern appretiert werden.According to the invention, both loose fibers and fibers processed into yarn or woven fabric can be used be finished.
