Description

Verfahren zum Waschen pflanzlicher Fasern Es wurde gefunden, daß man beim Waschen pflanzlicher Fasern mit härtebeständigen Waschmitteln inAlkalicarbonate enthaltenden Flotten, die mit hartem Wasser angesetzt sind, Abscheidungen wasserunlöslicher anor.-anischer Calcium- und Ma--liesiumsalze auf den Fasern verringern kann, wenn man den Waschflotten wasserlösliche Altiminate zusetzt.Process for washing vegetable fibers It has been found that when washing vegetable fibers with hardness-resistant detergents in alkali carbonates containing liquors which are made up with hard water, deposits of water-insoluble inorganic calcium and malesium salts on the fibers can be reduced, if water-soluble altiminates are added to the wash liquors.

Als härtebeständige Waschmittel seien beispielsweise genannt Waschmittel von der Zusainmensetzunz R-X-RI-So.-l#le oder R-O-SO.-Me, worin H R., X für -CH.,0-,-COO-,-CON-,-CO-N, R für einen aliphatischen Rest mit mindestens 7 Kohlenstoffatomen stehen kann und R, und R, einen aliphatischen oder aromatischen Rest und Me Alkalimetall oder Ammonium bedeuten. Ferner kommen solche Waschmittel in Detracht, die durch Anlagerung von Äthylenoxydgruppen an Verbindungen von der Zu-Sammensetzung worin R einen aliphatischen Rest mit mindestens 7 Kohlenstoffatomen, R, und R. einen aliphatischen oder aromatischen Rest bedeuteil, wasserlöslich gernacht worden sind.Hardness-resistant detergents may be mentioned, for example, detergents from the Zusainmensetzunz RX-RI-So.-l # le or RO-SO.-Me, wherein H R., X for -CH., 0 -, - COO -, - CON -, - CO-N, R can stand for an aliphatic radical having at least 7 carbon atoms and R, and R, an aliphatic or aromatic radical and Me mean alkali metal or ammonium. Furthermore, such detergents come into consideration, which are caused by the addition of ethylene oxide groups to compounds from the composition where R is an aliphatic radical having at least 7 carbon atoms, R, and R. is an aliphatic or aromatic radical, have been made water-soluble.

Es ist zwar bereits bekannt, seifenhaltigen Waschflotten Natriumaluminat hinzuzusetzen und Mischungen aus Barium- und Natriumalutninat zur Wasserreinigung zu verwenden. Z Xus diesen bekannten Verfahren konnte nicht geschlossen werden, daß durch die Zugabe von wasserlöslichen Alurninaten zu Härtebildner des Wassers und Alkalicarbonate enthaltenden Waschflotten, in denen als Waschmittel härtebeständige Waschmittel verwendet werden, die Menge der Abscheidungen von fa#serschädigenden anorganischen Metallz# salzen auf dem Waschgut verringert wird. Beispiele i. Bei Verwendung von 2g des Natriumsalzes des Palml<ernölfetts-,turetaurids je Liter in Wasser von 2o' D.H. unter Zusatz von 3 Soda im Liter Flotte reichern sich nach wiederholter Wasche auf dem Baumwollinaterial starke Abscheidungen von anorganischen Calcium- und Magnesiumsa17,en an. Bei Zugabe von o,4 g Natriumaluminat je Liter Waschflotte werden die Abscheidungen verringert. It is already known to add sodium aluminate to soap-containing washing liquors and to use mixtures of barium and sodium aluminate for water purification. It could not be concluded from these known processes that the addition of water-soluble aluminates to hardness builders in the washing liquors containing water and alkali carbonates in which hardness-resistant detergents are used, the amount of deposits of fiber-damaging inorganic metal salts on the laundry is decreased. Examples i. When using 2g of the sodium salt of palm oil fat, turetauride per liter in water of 2o 'DH with the addition of 3 soda per liter of liquor, strong deposits of inorganic calcium and magnesium salts accumulate on the cotton material after repeated washing. With the addition of 0.4 g of sodium aluminate per liter of wash liquor, the deposits are reduced.

2. Beim Kochen einer sodaalkalischen Flotte mit 4 -# des Natriumsalzes des Schwefelsaureesters vom Oleylalkohol, je Liter erhält das Waschgut in hartem Wasser infolge der Abscheiclungen von Caleiumcarbonat auf der Ware einen rauhen Griff, der durch Zugabe von etwa o,61- Natriumaluminat jeLiter Waschflotte verbessert werden kann.2. When boiling a soda-alkaline liquor with 4 - # of the sodium salt of the sulfuric acid ester of oleyl alcohol, per liter the items to be washed in hard water get a rough handle as a result of the deposits of calcium carbonate on the goods, which can be achieved by adding about 0.61 sodium aluminate per liter of washing liquor can be improved.

3. Bei wiederholter Wäsche in einer kochenden sodaalkalischen, mit hartem Wasser angesetzten Waschflotte, die 4 des Einwirkungsproduktes von Äthvlenoxvd auf Kokosölsätireäthanolamid im Liter enthält, entstehen auf dein Waschgut Ablagerungen von anorganischen Calcitun- und '#lagiiesiuiii-salzeii, die verringert werden, wenn flen Waschflotten 0,3 g Kaliunialtiminat je Liter zugegleben werden. 3. With repeated washing in a boiling, soda-alkaline wash liquor, which is prepared with hard water and which contains 4 liters of the product of the action of Äthvlenoxvd on coconut oil sätireäthanolamid, deposits of inorganic calcitunum and '# lagiiesiuiii-salzeii occur on your laundry, which are reduced when flowing Wash liquors 0.3 g Kaliunialtiminat per liter are added.
