Abstract
Description
Die vorliegende Erfindung betrifft neue Mittel zur gleichzeitigen Nachgerbung und Fettung von vorgegerbtem Leder oder Pelzen, Verfahren zur Herstellung dieser Mittel sowie die Verwendung dieser Mittel zur Herstellung von Leder oder Pelzen.The present invention relates to new agents for simultaneous retanning and oiling of pre-tanned leather or furs, processes for making these agents and the Use of these agents for the production of leather or furs.
Bei der Herstellung von Leder werden üblicherweise die vorgegerbten Häute neutralisiert, dann nachgegerbt, gefettet und gegebenenfalls anschliessend gefärbt und noch weiter ausgerüstet. Die mit der Neutralisation beginnenden Arbeitsgänge werden häufig in getrennten Bädem oder nacheinander in einem Bad durchgeführt, können aber auch in einem Bad gleichzeitig stattfinden. Die dabei eingesetzten Produkte werden meist einzeln in fester oder flüssiger Form verwendet, da es schwierig ist, homogene Mischungen herzustellen. Die Fettungsmittel sind nämlich fast ausschliesslich flüssig oder zumindest wachsartig und lassen sich mit den festen Komponenten, z.B. den Neutralisationsmitteln und Nachgerbstoffen, nach bisher bekannten Methoden nicht zu Mischungen verarbeiten, bei denen während ausreichend langer Zeit und auch bei unterschiedlichen Temperaturen eine homogene Verteilung der Komponenten und eine genügende Lagerstabilität gewährleistet sind.In the production of leather, the pre-tanned skins are usually neutralized, then retanned, greased and, if necessary, subsequently colored and even further equipped. The operations beginning with the neutralization are often in separate baths or carried out in succession in a bath, but can also in take a bath at the same time. The products used are usually individually in solid or liquid form used because it is difficult to mix homogeneous to manufacture. The fatliquors are almost exclusively liquid or at least wax-like and can be mixed with the solid components, e.g. the neutralizing agents and retanning agents, do not process into mixtures according to previously known methods, in which for a sufficiently long time and also at different temperatures a homogeneous distribution of the components and sufficient storage stability are guaranteed.
Es wurden nun neue Präparate gefunden, die eine bedeutende Vereinfachung der Nasszurichtung von Leder ermöglichen, da mit nur einem Mittel gleichzeitig das Nachgerben und das Fetten sowie eventuell noch weitere Behandlungen durchgeführt werden können. Dies ist dadurch bedingt, dass in diesen Mitteln Nachgerbmittel und Fettungsmittel in solcher Form vorliegen, dass sie bei der Zugabe zu der mindestens 8fachen Menge Wasser bei 10 bis 60 °C homogene Mischungen ergeben.New preparations have now been found which significantly simplify the process Allow wet dressing of leather, because with only one agent at the same time Retanning and greasing as well as possibly other treatments carried out can be. This is due to the fact that retanning agents and Fatting agents are present in such a form that they are added to the minimum 8 times the amount of water at 10 to 60 ° C give homogeneous mixtures.
Überraschenderweise tritt bei Verwendung der erfindungsgemässen Mittel,ein synergistischer Effekt auf. Man kann nämlich die Einsatzmenge an Nachgerb- und Fettungsmittel deutlich vermindern, gegenüber einer Arbeitsweise, bei der diese Chemikalien einzeln eingesetzt werden, obwohl die üblichen Nachgerb- und Fettungsmittel verwendet werden. Insbesondere ist die Fettemulgierung bei Verwendung der erfindungsgemässen Mittel verbessert und man kommt mit geringeren Mengen an Fettungsmitteln aus. Die erfindungsgemässen Mittel weisen eine hervorragende Lagerstabilität auf und sind frostfest, falls es sich um feste Mittel handelt.Surprisingly, occurs when the agents according to the invention are used synergistic effect. You can namely the amount of retanning and Significantly reduce fatliquoring, compared to a method in which this Chemicals are used individually, although the usual retanning and greasing agents be used. In particular, the fat emulsification when using the Improved agents according to the invention and one arrives with smaller amounts Fatty substances. The agents according to the invention are excellent Storage stability and are frost-resistant, if it is solid agents.
Bei Verwendung der erfindungsgemässen Mittel kann ausserdem der Transport- und Lageraufwand gegenüber der Verwendung spezieller Mittel für jeden einzelnen Behandlungsschritt deutlich reduziert werden und die Handhabung wird erheblich vereinfacht. Zudem bringen sie eine Wasser- und Zeitersparnis von bis zu 60 % und erleichtern die Reproduzierbarkeit der Qualität des erhaltenen Leders. Darüberhinaus wird durch die Verwendung der erfindungsgemässen Mittel die Penetration und Verteilung der Chemikalien in das Leder beschleunigt und/oder verbessert. Dies führt z.B. zu einer besseren Durchfärbung des Leders. Ausserdem werden weitere wichtige Eigenschaften des Leders, wie das Verhalten gegenüber Wassereinwirkung, Foggingverhalten, Haftfestigkeit von Zurichtfilmen, Dehnungs- und Festigkeitseigenschaften sowie die Flächenmasse vorteilhaft beeinflusst.When using the means according to the invention, the transport and Storage effort compared to the use of special funds for each individual Treatment step can be significantly reduced and handling becomes significant simplified. They also save up to 60% water and time facilitate the reproducibility of the quality of the leather obtained. Furthermore, through the use of the agents according to the invention the penetration and distribution of the Chemicals in the leather are accelerated and / or improved. This leads e.g. to a better coloring of the leather. In addition, other important properties of the leather, such as the behavior towards water, fogging behavior, Adhesion strength of dressing films, stretch and strength properties as well as the Basis mass advantageously influenced.
