Description
Verfahren zum Wasserabstoßendmachen von Wollfasergut Textilfasern, auch Wollfasern, können nach einem Imprägnieren mit Aluminiumacetat bzw. -formiat durch heißes Trocknen oder durch Dämpfen infolge Abscheidung gallertiger Aluminiumhydroxydniederschläge auf den Fasern wasserabstoßend gemacht werden. Werden an Stelle der genannten Salze mineralsaure Aluminiumsalze, also heispielswe.ise Aluminiumsulfat, zur Imprägnierung von Wollfasern verwendet, so ist es nicht möglich, durch heißes Trocknen, selbst bei Temperaturen bis ioo°,oder durch Dämpfen den vorstehendgeschilderten Vorgang zu bewirken, denn das mineralsaure Alnm@niumsalz, z. B. Aluminiumsulfat, verbleibt als, solches auf bzw. in den Fasern, -die ihre ursprüngliche Wasseraufsaugfähigkeit behalten.Process for making woolen fiber fabric textile fibers water-repellent, wool fibers can also be used after impregnation with aluminum acetate or aluminum formate by hot drying or by steaming as a result of the separation of gelatinous aluminum hydroxide precipitates made water-repellent on the fibers. Are in place of the mentioned salts Mineral acid aluminum salts, for example aluminum sulfate, for impregnation Used by wool fibers, so it is not possible, by hot drying, by yourself at temperatures up to 100 °, or by steaming the process described above to cause, because the mineral acid Alnm @ nium salt, z. B. aluminum sulfate remains as, on or in the fibers, -that their original water absorbency keep.
Gegenstand der Erfindung ist nun das Wasserfestmachen von Wollfasergut in der Weise, daß man, es bei gewöhnlicher oder wenig erhöhter Temperatur mit einer Lösung mineralsaurer Aluminiumsalze, insbesondere etwa 5 bis 2o%igel, wässerigen Alnminiumsulfatlösungen, kurze Zeit tränkt und unmittelbar danach ohne eine Zwischentrocknung in, ein Bad großer Mengen siedenden Wassers einführt, das das auf bzw. in die Wollfaser gebrachte Aluminiumsulfat zersetzt unter Abscheidung des gallertigen Aluminiumhydroxydnjederschlages; aus der Tatsache, daß das zweite, das Fixierbad, hierbei: vollkommen klar bleibt, ist erkennbar, daß die Hydrolyse des Aluminiumsulfates nicht im Bad selbst, sondern nur auf bzw. in den Wollfasern stattfindet. . Von den bekannten Wollbeizverfahren mit Aluminiumsulfat unterscheidet sich das neue Verfahren dadurch, daß die Wollfaser zuerst in -einem Aluminiumsulfatbad von viel höherer Konzentration, als beim Wollbeizen üblich, behandelt wird, und zwar in der Kälte, also auch bei wesentlich niederer Temperatur sowie in kürzerer Zeit als beim Wollebeizen; die Wollfasern werden dabei mit Aluminiumsulfat nur getränkt, ohne daß das Aluminiumsalz .auf .die Wollfasern !einwirkt.The subject of the invention is the waterproofing of wool fiber material in such a way that you can do it at ordinary or slightly elevated temperature with a Aqueous solution of mineral acid aluminum salts, in particular about 5 to 20% gel Aluminum sulfate solutions, soak for a short time and immediately afterwards without intermediate drying in, a bath of large amounts of boiling water introduces that on or into the wool fiber The aluminum sulphate that has been applied decomposes with the separation of the gelatinous aluminum hydroxide impact; from the fact that the second, the fixer, remains perfectly clear, it can be seen that the hydrolysis of the aluminum sulfate is not in the bath itself, but only takes place on or in the wool fibers. . From the well-known wool pickling process With aluminum sulfate, the new process differs in that the wool fiber first in an aluminum sulphate bath of a much higher concentration than when pickling wool usual, is treated, namely in the cold, so also in much lower Temperature as well as in a shorter time than for wool staining; the wool fibers are there just impregnated with aluminum sulfate without the aluminum salt on the wool fibers ! acts.
Die Möglichkeit, ohne weiteres .das billige Aluminiumsulfat verwenden zu können, bedeutet bei der Wasserfes.tmachung die Ersparnis der sonst meist nötigen umständlichen vorherigen Umwandlung des Aluminiumsulfates in Aluminiumacetat oder in Aluminiumformiat. Zudem kann das neue Verfahren in jedem beliebigen Fabrikationsstadium der Verarbeitung der Fasern vorgenommen werden. Beispiel Man bringt i oo kg Wollfasern, Wollkammzug, Wollgarne, Wollgewebe, Wollgestricke oder Wollfilze in ein kaltes bis lauwarmes Bad von i ooo 1 Wasser, in dem zuvor i oo kg Aluminiumsulfat gelöst werden, und läßt die Ware darin 1/2 Stunde, wobei nur eine giteringe Bewegung der Ware oder der Flüssigkeit notwendig ist. Hierauf wird die Ware abgepreßt oder ,abgeschleudert und alsdann, ohne zu trocknen, in frischem Bade von ioool siedenden Wassers etwa 1/2 Stunde lang behandelt. Zweckmäßigerweise gibt man bei Wollfasern diesem Bade i kg 6oooiger Essigsäure: zu. - Die beiden gebrauchten Bäder können nach Wiederzurichtung ohne weite-' res wiederholt benutzt. werden.The possibility of using the cheap aluminum sulphate without further ado Being able to do so means saving what is usually necessary when it comes to making water cumbersome previous conversion of aluminum sulfate into aluminum acetate or in aluminum formate. In addition, the new process can be used at any manufacturing stage the processing of the fibers. Example One brings i oo kg of wool fibers, Combed wool, wool yarns, woolen fabrics, knitted woolen fabrics or wool felts in a cold to lukewarm bath of 10000 water, in which 100 kg of aluminum sulphate are dissolved beforehand, and leaves the goods in it for 1/2 hour, with only a slight movement of the goods or the liquid is necessary. The goods are then squeezed off or thrown off and then, without drying, in a fresh bath of cool boiling water Treated for 1/2 hour. Appropriately, one gives with wool fibers this bath i kg 600 acetic acid: to. - The two used bathrooms can used repeatedly after being re-arranged without further ado. will.
