Description

Das Schlichten von Fasermaterial mit Polyvinylalkohol (PVAI) ist in der Technik gut bekannt. Besonders Polyvinylalkohole mit unterschiedlichem Verseifungsgrad, d. h. unterschiedlichem Restacetylgehalt haben sich in der Praxis als Schlichtemittel bewährt.Sizing fiber material with polyvinyl alcohol (PVAI) is well known in the art. Especially polyvinyl alcohols with different degrees of saponification, i. H. Different levels of residual acetyl have proven themselves in practice as sizing agents.

Der Einsatz von Polyvinylalkohol beim Schlichten von Filamenten ist aber in der Praxis nicht unumstritten, da speziell hydrophobe Filamente in Abhängigkeit vom Polymerisationsgrad des Polyvinylalkohols stark unterschiedliche Schlichteergebnisse zeigen. Finch beschreibt in »Polyvinylalkohole S. 261 ff.« die Schwierigkeiten für Polyvinylalkohole als Schlichtemittel bei hydrophoben Filamenten, z. B. Polyester. Der PVAI-Schlichtefilm ist auf diesen Fäden sehr spröde und kann deshalb beim Weben durch Absplittern Webfehler verursachen. Verbesserungen bringen laut Finch (loc. cit.), Zusätze von plastifizierenden Additiven und Acrylatschlichten, die in Mischung mit dem Polyvinylalkohol eingesetzt werden. Jedoch können diese Additive den Polyvinylalkoholfilm klebrig und zäh machen. Die zugemischte Acrylatschlichte haftet zwar sehr gut am Polyester, jedoch ist die Acrylatschlichte hygroskopisch und in der Haftlänge und Festigkeit dem Polyvinylalkohol deutlich unterlegen. Das Problem der Empfindlichkeit von Acrylatschlichten bei Filamenten gegenüber Spulölen und Spinnpräparation soll hier nur ergänzend erwähnt werden.The use of polyvinyl alcohol in the sizing of filaments is not without controversy in practice, since hydrophobic filaments in particular show very different sizing results depending on the degree of polymerization of the polyvinyl alcohol. Finch describes in "Polyvinyl alcohols p. 261 ff." The difficulties for polyvinyl alcohols as sizing agents in hydrophobic filaments, e.g. B. polyester. The PVAI size film is very brittle on these threads and can therefore cause weaving errors due to chipping. According to Finch (loc. Cit.), Improvements result in additions of plasticizing additives and acrylate sizes, which are used in a mixture with the polyvinyl alcohol. However, these additives can make the polyvinyl alcohol film sticky and tough. The admixed acrylate size adheres very well to the polyester, but the acrylate size is hygroscopic and clearly inferior in length and strength to the polyvinyl alcohol. The problem of the sensitivity of acrylic sizes in filaments to winding oils and spin preparation should only be mentioned here in addition.

Es wurde nun gefunden, daß man Schlichten aus Polyvinylalkohol sehr flexibel und weich machen kann, so daß sie mit sehr gutem Erfolg für das Schlichten hydrophober Fasern eingesetzt werden können, wenn man den üblichen Polyvinylalkoholschlichten ein Aminoxid zusetzt.It has now been found that sizes made from polyvinyl alcohol can be made very flexible and soft, so that they can be used with very good results for the size of hydrophobic fibers if an amine oxide is added to the usual polyvinyl alcohol sizes.

Gegenstand der Erfindung ist somit ein Schlichtemittel bestehend aus einem Polyvinylalkohol und 1 bis 30, vorzugsweise 5 bis 15 Gew.-%, bezogen auf den Polyvinylalkohol eines Aminoxids der Formel

wobei R1 C5-C22-Alkyl oder -Alkenyl, R2 C1-C22-Alkyl oder -Alkenyl oder eine Gruppe der Formel -(CH2CH20)nH, n eine Zahl von 1 bis 5 und R3 C1―C5-Alkyl ist oder R3 ist eine Gruppe der Formel - (CH2CH20)mH, wenn R2 für eine Alkylgruppe mit mehr als 5 C-Atomen steht und m ist eine Zahl von 1 bis 10, wobei die Summe von n + m nicht größer als 10 ist.The invention thus relates to a sizing agent consisting of a polyvinyl alcohol and 1 to 30, preferably 5 to 15% by weight, based on the polyvinyl alcohol of an amine oxide of the formula
Figure imgb0001
 wherein R 1 C 5 -C 22 alkyl or alkenyl, R 2 C 1 -C 22 alkyl or alkenyl or a group of the formula - (CH 2 CH 2 0) n H, n is a number from 1 to 5 and R 3 is C 1 ―C 5 alkyl or R 3 is a group of the formula - (CH 2 CH 2 0) m H if R 2 is an alkyl group with more than 5 C atoms and m is a number of 1 to 10, where the sum of n + m is not greater than 10.

Diese Aminoxide sind aus der DE-C-2 326 966 bekannt. Sie leiten sich ab von natürlich vorkommenden Fettsäuren, die in vielen Fällen Gemische darstellen von Produkten mit unterschiedlicher Länge der Alkylkette. Daneben können diese natürlichen Fettsäuren bekanntlich auch unterschiedliche Mengen an ungesättigten Fettsäuren enthalten. Dementsprechend kommen erfindungsgemäß auch Mischungen von Aminoxiden mit unterschiedlicher Länge der Alkylgruppe in Frage, wobei diese Gruppen außerdem ungesättigt sein können. Die Aminoxide sind mit den Polyvinylalkohol-typen voll verträglich und werden dem Schlichtebad in der angegebenen Konzentration zugegeben. Die Konzentration des beanspruchten Schlichtemittels in der Schlichteflotte beträgt üblicherweise 2-20 Gew.-%. Neben dem Polyvinylalkohol und dem Aminoxid können der Schlichteflotte auch andere Additive wie emulgierte Fette, Mineralöle, Stärke, Stärkeäther u. a. zugesetzt werden. Das erfindungsgemäße Schlichtemittel eignet sich hervorragend zum Schlichten von hydrophoben Synthesefasern, insbesondere von Polyester.These amine oxides are known from DE-C-2 326 966. They are derived from naturally occurring fatty acids, which in many cases are mixtures of products with different lengths of the alkyl chain. As is known, these natural fatty acids can also contain different amounts of unsaturated fatty acids. Accordingly, mixtures of amine oxides with different lengths of the alkyl group are also possible according to the invention, it also being possible for these groups to be unsaturated. The amine oxides are fully compatible with the types of polyvinyl alcohol and are added to the size bath in the specified concentration. The concentration of the claimed sizing agent in the sizing liquor is usually 2-20% by weight. In addition to polyvinyl alcohol and amine oxide, the sizing liquor can also contain other additives such as emulsified fats, mineral oils, starch, starch ether and the like. a. be added. The sizing agent according to the invention is outstandingly suitable for sizing hydrophobic synthetic fibers, in particular polyester.

Nach dem Trocknen erhält man durch den Zusatz der Aminoxide klare Schlichtefilme hoher Flexibilität. Die Aminoxide schwitzen nicht aus den getrockneten Filmen aus und erhöhen auch nicht deren Hygroskopizität, verstärken aber die Klebkraft der PVAL-Schlichten.After drying, the addition of the amine oxides gives clear size films of high flexibility. The amine oxides do not exude from the dried films and do not increase their hygroscopicity, but increase the adhesive strength of the PVAL sizes.

Der Fadenschluß wurde bestimmt nach Melliand-Textilberichte 58 (1977), S. 187-194. Die Pendelhärte wurde mit einem Härteprüfgerät gemessen, wobei die obigen Zahlen die Anzahl der Schwingungen angibt, die das Pendel bis zum Stillstand ausführt. Der erfindungsgemäße Zusatz eines Aminoxids bewirkt eine Erhöhung der Flexibilität der Schlichtefilme, wobei deren Wasseraufnahme kaum steigt. Die Pendelhärte als Maß für die Sprödigkeit geht ebenfalls zurück, während der Fadenschluß als entscheidendes Kriterium für die Klebkraft ansteigt.The thread closure was determined according to Melliand Textile Reports 58 (1977), pp. 187-194. The pendulum hardness was measured with a hardness tester, the numbers above showing the number of vibrations that the pendulum executes until it stops.
