Description

Fettungsmittel für Materialien faseriger Struktur Gegenstand des Patents 942 889 ist die Verwendung von Chlorierungserzeugnissen geradkettiger oder nur wenig verzweigter aliphatischer Kohlenwasserstoffe mit wenigstens 8 Kohlenstoffatomen zum Fetten von Materialien faseriger Struktur.Fatliquor for materials of fibrous structure is the subject of the patent 942 889, the use of chlorination products is more straight-chain or only slightly branched aliphatic hydrocarbons having at least 8 carbon atoms for greasing materials with a fibrous structure.

Bei der Anwendung dieser Stoffe hat es sich gezeigt, daß sie zum Teil mehr oder weniger starke Hautreizungen hervorrufen. Es wurde nun gefunden, daß dieser Nachteil mit Sicherheit vermieden werden kann, ohne daß die vorzüglichen fettenden Eigenschaften der genannten Stoffe beeinträchtigt werden, wenn man sie vor ihrer Verwendung von beigemengten flüchtigen Bestandteilen befreit, zum Beispiel durch Behandlung mit Wasserdampf oder Gasen bei erhöhter Temperatur, z. B. zwischen etwa 8o und 130 ° C. Es handelt sich dabei im allgemeinen nur um geringe Mengen von Begleitstoffen, etwa in der Größenordnung um i %.When using these substances it has been shown that they are partly cause more or less severe skin irritation. It has now been found that this Disadvantage can be avoided with certainty, without the excellent greasy Properties of the substances mentioned are impaired if you look at them before their Use of added volatile components exempted, for example by Treatment with steam or gases at elevated temperature, e.g. B. between about 8o and 130 ° C. These are generally only small amounts of accompanying substances, around i%.

Beispielsweise leitet man durch das im ersten Absatz von Beispiel i des Hauptpatents angegebene Chlorierungserzeugnis eine Zeitlang Wasserdampf bei roo bis 105 ° C. Das so behandelte Erzeugnis kann unmittelbar auf die in dem genannten Beispiel beschriebene Weise weiterverarbeitet werden. In ähnlicher Art verfährt man bei anderen, den erwähnten Nachteil zeigenden Chlorierungserzeugnissen.For example, through the chlorination product specified in the first paragraph of example i of the main patent, steam is passed for a time at roo to 105 ° C. The product treated in this way can be further processed immediately in the manner described in the example mentioned. A similar procedure is followed for other chlorination products showing the disadvantage mentioned.

PATENTANSPRUCH: Verwendung von Chlorierungsprodukten von synthetischen, durch Hydrierung von Kohle oder der Oxyde des Kohlenstoffs gewonnenen aliphatischen geradkettigen bzw. wenig verzweigten Kohlenwasserstoffen mit wenigstens 8 Kohlenstoffatomen als Fettungsmittel für Materialien faseriger Struktur allein oder zusammen mit anderen Fettungsmitteln, gegebenenfalls unter Zusatz von Emulgatoren gemäß Patent 9422 889, dadurch gekennzeichnet, daß man die Chlorierungsprodukte nach der Entfernung flüchtiger Beimengungen anwendet. PATENT CLAIM: Use of chlorination products of synthetic aliphatic straight-chain or slightly branched hydrocarbons with at least 8 carbon atoms obtained by hydrogenation of coal or the oxides of carbon as fatliquoring agents for materials with a fibrous structure alone or together with other fatliquoring agents, optionally with the addition of emulsifiers according to patent 9422 889, characterized in that the chlorination products are used after volatile additions have been removed.
