Description

Verfahren zur Verbesserung der Eigenschaften textiler Gebilde aus anorganischen Stapelfäsern Textile Gebilde, insbesondere Garne und Gewebe, aus Stapelfasern anorganischen Ursprungs, wie Glas oder Asbest, die in der Technik für verschiedenste Verwendungszwecke eingesetzt werden können, besitzen den Nachteil, daß sie bei mechanischer Beanspruchung mehr oder weniger verschleißen, was im wesentlichen auf eine zu hohe Empfindlichkeit derartiger Gebilde gegen Scheuern, Reiben und Knicken zurückzuführen ist. Außerdem besitzen diese Gebilde, insbesondere diejenigen aus Glasstapelfasern, den Nachteil, daß sie bei der Verarbeitung, z. B. beim Konfektionieren bzw. Zuschneiden, splittern, wobei ein sehr feiner Staub entsteht, der sich z. B. für die damit beschäftigten Personen gesundheitlich nachteilig auswirken kann. Bekanntlich werden z. B. Glasstapelfasern nicht, wie dies z. B. bei Glasseidefäden der Fall ist, geschlichtet, sondern lediglich -mit einer Art Schmälze behandelt, die das Verspinnen erleichtern soll. Die daraus hergestellten Garne und textilen Gebilde sind daher im Griff verhältnismäßig weich, was in vielen Fällen ebenfalls von Nachteil ist; auch aus Asbestfasern hergestellte Gebilde weisen diesen Nachteil auf.Process for improving the properties of textile structures Inorganic staple fibers Textile structures, in particular yarns and fabrics, made from staple fibers of inorganic origin, such as glass or asbestos, which are used in technology for the most diverse Uses can be used, have the disadvantage that they are mechanical Stress more or less wear out, which is essentially too high Due to the sensitivity of such structures to chafing, rubbing and kinking is. In addition, these structures, especially those made of staple glass fibers, the disadvantage that they are used in processing, e.g. B. when assembling or cutting, splinter, creating a very fine dust that z. B. for those involved Can be detrimental to health. It is well known that z. B. Glass staple fibers not like this e.g. B. is the case with fiberglass threads, sized, but only -treated with a kind of sludge that is supposed to make spinning easier. The one from it manufactured yarns and textile structures are therefore relatively soft to the touch, which is also a disadvantage in many cases; also made from asbestos fibers Structures have this disadvantage.

Es wurde nun gefunden, daß textile Gebilde aus anorganischen Stapelfasern weitgehend in ihren Eigenschaften verbessert werden können, wenn man sie mit wäßrigen Dispersionen wasserunlöslicher Polymerisate von Acrylsäureestern, Methacrylsäureestern oder Vinylestern behandelt. Für die Behandlung eignen sich auch die wäßrigen Dispersionen von Mischpolymerisaten der genannten Ester untereinander oder miteinander sowie auch von Mischpolymerisaten von Styrol. Zur Durchführung des Verfahrens werden die Gebilde aus den anorganischen Stapelfasern, z. B. Gewebe; in eine etwa 21/2 bis 5°/öge wäßrige Dispersion der genannten Polymerisate eingetaucht, abgequetscht und anschließend bei hierfür üblichen Temperaturen, z. B. 5o bis 8o°, getrocknet. Sofern dabei Polymerisate verwendet werden, die in Wasser nicht oder nur geringfügig quellbar sind, ist die durch die Behandlung erzielte Wirkung auch gegen die Einwirkung von Wässer beständig, was im Hinblick auf die technische Verwendung derartiger Gebilde vielfach von Vorteil sein kann. Mischpolymerisate aus Vinylchlörid und Vinylacetat sind neben anderen hierfür besonders geeignet.It has now been found that textile structures made of inorganic staple fibers Their properties can be improved to a large extent if they are treated with aqueous Dispersions of water-insoluble polymers of acrylic acid esters, methacrylic acid esters or vinyl esters treated. The aqueous dispersions are also suitable for the treatment of copolymers of the esters mentioned with one another or with one another as well as copolymers of styrene. To carry out the procedure will be the structures made from the inorganic staple fibers, e.g. B. Fabric; into a roughly 21/2 up to 5 ° / öge aqueous dispersion of the polymers mentioned immersed, squeezed off and then at temperatures customary for this purpose, e.g. B. 5o to 8o °, dried. Provided that polymers are used that are not or only slightly in water are swellable, the effect achieved by the treatment is also against the action Resistant to water, what with regard to the technical use of such structures can be beneficial in many ways. Copolymers of vinyl chloride and vinyl acetate are particularly suitable for this purpose, among others.

Durch die erfindungsgemäße Behandlung wird außerdem der Griff der Gebilde verbessert, wobei jedoch keine direkte Versteifung der Gebilde, sondern im wesentlichen eine Verfestigung des Fadenverbandes eintritt, so z. B. im Falle von Geweben eine wesentlich verbesserte Schiebefestigkeit. Dies macht sich besonders beim Schneiden der Gebilde, vor allem der Gewebe, vorteilhaft bemerkbar, da hierbei ohne die erfindungsgemäße Behandlung leicht Verletzungen des Gefüges (Ausfransen usw.) und starkes Stauben auftreten können. Schließlich ist die Widerstandsfähigkeit der nach dem Verfahren behandelten Gewebe aus anorganischen Stapelfasern gegenüber mechanischer Scheuerung zum Teil bis zu ioo °1o im Vergleich zu den unbehandelten Geweben gesteigert. .Auch die Reibfestigkeit und Knickfestigkeit werden wesentlich erhöht.The treatment according to the invention also makes the handle of the Improved structure, but no direct stiffening of the structure, but essentially a solidification of the thread association occurs, so z. B. in the case of fabrics a significantly improved slip resistance. This makes it special when cutting the structure, especially the tissue, advantageously noticeable, since this is the case Without the treatment according to the invention, the structure is easily damaged (fraying etc.) and heavy dusting can occur. Finally, there is resilience compared to the fabric made of inorganic staple fibers treated according to the method mechanical abrasion sometimes up to 100 ° 1o compared to the untreated Tissues increased. The friction resistance and buckling resistance are also essential elevated.

Es kann mitunter vorteilhaft sein, den wäßrigen Dispersionen, die die Polymerisate enthalten, noch wasserunlösliche Plastifizierungsmittel zuzusetzen, da hierdurch die Geschmeidigkeit und Elastizität der behandelten Gebilde noch verbessert werden können. Derartige Plastifizierungsmittel sind z. B. Phthalsäureester und andere in der Lackindustrie verwendete Mittel.It can sometimes be advantageous to use the aqueous dispersions the polymers contain the addition of water-insoluble plasticizers, as this improves the suppleness and elasticity of the treated structures can be. Such plasticizers are z. B. phthalic acid ester and other agents used in the paint industry.

Es ist bereits bekannt, Textilien organischen Ursprungs in der beanspruchten Weise mit Polymerisaten zu appretieren.It is already known that textiles of organic origin in the claimed Way to finish with polymers.
