Abstract

Schlichtemittel bestehend aus Polyvinylalkohol und Polyglycerin.Sizing agents consisting of polyvinyl alcohol and polyglycerin.

Description

Das Schlichten von hydrophilen Fasern, wie z.B. Cellulose, mit Polyvinylalkohol (PVA) ist in der Technik gut bekannt. Besonders Polyvinylalkohole mit.unterschiedlichem Verseifungsgrad, d.h: unterschiedlichem Restacetylgehalt, haben sich in der Praxis als Schlichtemittel bewährt. Schwierigkeiten ergeben sich aber beim Schlichten von Hydrophoben.Fasern, wie etwa Polyester, mit Polyvinylalkohol, da der Schlichtefilm auf diesen Fasern sehr spröde ist und deshalb beim Weben durch Absplittern Webfehler verursachen kann. In "C.A.Finch, Polyvinylalkohol, 1973 S. 260 ff" wird deshalb für Polyester ein kombiniertes Schlichtemittel beschrieben, das aus Polyvinylalkohol und Polyacrylat besteht. Die zugemischte Acrylatschlichte haftet zwar sehr gut an Polyester, bewirkt jedoch einen unerwünschten Anstieg der Hygroskopizität des Schlichtefilms auf der Faser. Es stellte sich daher die Aufgabe, bessere Additive zu finden, die ein optimales Schlichten von Synthesefasern mit Polyvinylalkohol gewährleisten.Sizing hydrophilic fibers, e.g. Cellulose with polyvinyl alcohol (PVA) is well known in the art. In particular, polyvinyl alcohols with different degrees of saponification, i.e. different levels of residual acetyl, have proven themselves in practice as sizing agents. Difficulties arise when sizing hydrophobic fibers, such as polyester, with polyvinyl alcohol, since the sizing film on these fibers is very brittle and can therefore cause weaving errors due to splinters during weaving. "C.A. Finch, Polyvinylalkohol, 1973 p. 260 ff" therefore describes a combined sizing agent for polyester, which consists of polyvinyl alcohol and polyacrylate. The admixed acrylate size adheres very well to polyester, but causes an undesirable increase in the hygroscopicity of the size film on the fiber. It was therefore the task to find better additives that ensure optimal sizing of synthetic fibers with polyvinyl alcohol.

Es wurde nun gefunden, daß man Schlichten aus Polyvinylalkohol flexibel und weich machen kann, so daß sie gut für das Schlichten von Synthesefasern, insbesondere von Polyester, eingesetzt werden können, wenn man der Polyvinylalkohol-Schlichte ein Polyglycerin zugibt.It has now been found that sizes from polyvinyl alcohol can be made flexible and soft, so that they can be used well for the size of synthetic fibers, in particular polyester, if a polyglycerol is added to the polyvinyl alcohol size.

Gegenstand der Erfindung ist ein Schlichtemittel, bestehend aus einem Polyvinylalkohol und 5 bis 30, vorzugsweise 8 bis 15 Gew.-%, bezogen auf das Gewicht des Polyvinylalkohols, eines Polyglycerins der Formeln

 where n are numbers from 2 to 13 and m are numbers from 1 to 7.

Für das erfindungsgemäße Schlichtemittel wird Polyvinylalkohol mit einer möglichst niedrigen Viskosität eingesetzt, so z.B. Typen mit einem Rest-Acetylgehalt von 1 bis 15.% und einer Viskosität von 4 - 18 m Pas, gemessen bei 20°C an einer 4 %igen wässrigen Lösung. Die Polyglycerine sind bekannt aus Fieser und Fieser, Organische Chemie 1968, S. 1230. Diese Polyglycerine werden bevorzugt in die heiße, wäßrige Flotte des Polyvinylalkohols gegeben. Die Konzentration des Schlichtemittels, also der Mischung von Polyvinylalkohol und Polyglycerin, in der Schlichteflotte beträgt üblicherweise 2 bis 20 Gew.%.For the sizing agent according to the invention, polyvinyl alcohol with the lowest possible viscosity is used, e.g. Types with a residual acetyl content of 1 to 15% and a viscosity of 4 - 18 m Pas, measured at 20 ° C on a 4% aqueous solution. The polyglycerols are known from Fieser and Fieser, Organic Chemistry 1968, p. 1230. These polyglycerols are preferably added to the hot, aqueous liquor of polyvinyl alcohol. The concentration of the sizing agent, that is to say the mixture of polyvinyl alcohol and polyglycerol, in the sizing liquor is usually 2 to 20% by weight.

Neben dem Polyvinylalkohol und dem Polyglycerin können der Schlichteflotte auch andere Additive wie emulgierte Fette, Mineralöle, Antioxidantien, Stärke, Stärkeäther u.a. zugesetzt werden. Das erfindungsgemäße Schlichtemittel eignet sich hervorragend zum Schlichten von hydrophoben Synthesefasern, wie Polyacrylnitril, Polypropylen und insbesondere Polyester sowie Mischungen dieser Fasern mit nativen Fasern oder Cellulose-2 1/2-Acetat- oder Cellulose-triäcetat-Fasern. Die Auflage an Schlichtemittel auf dem Garn liegt innerhalb der in der Praxis üblichen Grenzen, beispielsweise 6 bis 8 Gew.% für eine Kette aus texturierten Polyesterfasern.In addition to polyvinyl alcohol and polyglycerol, the sizing liquor can also contain other additives such as emulsified fats, mineral oils, antioxidants, starch, starch ether, etc. be added. The sizing agent according to the invention is outstandingly suitable for sizing hydrophobic synthetic fibers, such as polyacrylonitrile, polypropylene and in particular polyester, and also mixtures of these fibers with native fibers or cellulose-2 1/2 acetate or cellulose triacetate fibers. The amount of sizing agent on the yarn is within the usual limits in practice, for example 6 to 8% by weight for a chain made of textured polyester fibers.

Nach dem Trocknen erhält man durch den Zusatz der Polyglycerine klare Schlichtefilme hoher Flexibilität. Die Polyclycerine 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 polyglycerols gives clear size films of high flexibility. The poly clycerins do not exude from the dried films and do not increase their hygroscopicity, but they do increase the adhesive strength of the PVAL coatings.
