In der deutschen Auslegeschrift 1 201 296 ist ein Verfahren zur Herstellung von gefärbten Fasern aus Poly-a-olefinen vorgeschlagen worden, wobei eine basische Substanz oder eine anionische Austauschsubstanz, die ein Metall der Gruppe II a, II b oder IV a fies Periodensystems enthält, dem Polyolefin beigemischt wird, und zwar vor dem Färben mit einem Farbstoff, der eine oder mehrere saure Gruppen mit einem niedrigen Ionisationsgrad enthält, wodurch ein Salz oder eine Gleitverbindung des Metalls mit dem !Farbstoff hergestellt wird.The German Auslegeschrift 1 201 296 describes a method for producing colored fibers from Poly-α-olefins have been proposed, with a basic substance or an anionic exchange substance which is a metal from group II a, II b or IV a contains nasty periodic table, mixed with the polyolefin before dyeing with a dye containing one or more acidic groups contains a low degree of ionization, whereby a salt or a sliding compound of the metal with the ! Dye is produced.
Gemäß der französischen Patentschrift 1235 806 werden die Eigenschaften von Polyolefin durch die Einarbeitung gewisser Metallseifen verbessert. Insbesondere ergibt sich hierdurch eine Verbesserung der Färbeeigenschaften. Die in dieser französischen Patentschrift beschriebenen Massen enthalten jedoch keine Stoffe zur Stabilisierung des Polyolefins gegen Abbau. Die der vorliegenden Erfindung zugrunde liegende Aufgabe wird deshalb von dieser Patentschrift nicht berührt.According to French patent 1235 806 the properties of polyolefin are improved by the incorporation of certain metal soaps. In particular This results in an improvement in the coloring properties. The one in this French However, the compositions described in the patent contain no substances to stabilize the polyolefin against Dismantling. The object on which the present invention is based is therefore addressed by this patent specification not touched.
Es wurde nun festgestellt, daß die Metallseifen die schützende Wirkung der Substanzen, die zur Verminderung der Zersetzungsneigung zu der Poly-a-olefinjnasse zugegeben werden, in nachteiliger Weise beeinflussen.It has now been found that the metallic soaps reduce the protective effect of the substances used the tendency to decompose to the wet poly-α-olefin are added, adversely affect.
Es wurde auch festgestellt, daß diese durch Metallreifen hervorgerufene nachteilige Beeinflussung der Wirkung der stabilisierenden Substanzen in hohem Maße durch die Verwendung von Metallseifen organische Säuren mit verzweigten Kohlenstoffketten herabgesetzt werden kann.It was also found that this was caused by metal hoops caused adverse influence on the effect of the stabilizing substances to a high degree Reduced levels of organic acids with branched carbon chains through the use of metallic soaps can be.
Gegenstand der vorliegenden Erfindung ist daher till Verfahren zum Herstellen von Fasern oder Fäden durch Schmelzspinnen von Poly-a-olefinen, die eine Beimischung von Metallsalzen und wenigstens einen üblichen, die Zersetzung verhindernden Stabilisator enthalten, welches dadurch gekennzeichnet ist, daß man als Metallseifen 1 bis 10 Gewichtsprozent des Salzes einer organischen Monocarbonsäure oder einer Mischung von Monocarbonsäuren mit einem Metall der Gruppella, Hb oder IVa des Periodensystems verwendet, wobei die Carboxylgruppe an ein Atom einer verzweigten Kohlenstoffkette gebunden ist sowie 0,1 bis 5 Gewichtsprozent des Stabilisators oder Stabilisatorgemisches beimischt.The present invention therefore relates to a method for producing fibers or threads by melt spinning of poly-a-olefins, which is an admixture of metal salts and at least one conventional, the decomposition preventing stabilizer, which is characterized in that as metal soaps 1 to 10 percent by weight of the salt of an organic monocarboxylic acid or a Mixture of monocarboxylic acids with a metal from Gruppella, Hb or IVa of the periodic table used, wherein the carboxyl group is bonded to an atom of a branched carbon chain and 0.1 to 5 percent by weight of the stabilizer or stabilizer mixture admixed.

leicht gefärbt durch die Farbstoffe des britischen Patents 935 125, die eine oder mehrere saure Gruppen mit einem niedrigen Dissoziationsgrad, wie anschließend erläutert, aufweisen, durch die ein Salz oder eine Chelatverbindung des Metalls mit dem Farbstoff hergestellt wird.lightly colored by the dyes of British Patent 935 125 containing one or more acidic groups with a low degree of dissociation, as explained below, have a salt or chelating the metal with the dye.
Eine einen niedrigen Dissoziationsgrad aufweisende saure Gruppe ist z. B. eine phenolische Hydroxyl- oder eine Carboxylgruppe, die in Wasser bei 20° C eine Dissoziationskonstante von weniger als 10~2 besitzt. Farbstoffe dieser Art sind in Form ihrer freien Säure in normaler wäßriger Lösung bei 2O0C zu weniger als 10% ionisiert. Erfindungsgemäß verwendete Metallseifen, die Metalle der Gruppella, Hb und IVa des Periodensystems enthalten, sind z. B. die aliphatischen carbonsauren Salze von Mg, Ca, Sr, Ba, Cd, Zn, Sn und Pb.An acidic group having a low degree of dissociation is e.g. B. having a phenolic hydroxyl group or a carboxyl group which in water at 20 ° C a dissociation constant of less than 10 ~. 2 Dyes of this type are ionized their free acid in normal aqueous solution at 2O 0 C to less than 10% in the form. Metal soaps used according to the invention which contain metals from Gruppella, Hb and IVa of the periodic table are, for. B. the aliphatic carboxylic acid salts of Mg, Ca, Sr, Ba, Cd, Zn, Sn and Pb.
Die organische Säure, von der sich die Metallseife ableitet, hat vorzugsweise wenigstens 8 Kohlenstoffatome in der Kette, damit die Metallseife im PoIya-olefin löslich und mit ihm verträglich ist. Es wurde festgestellt, daß die organischen Monocarbonsäuren sehr geeignet sind, die die Carboxylgruppe an verzweigten Kohlenstoffketten mit 8 bis 20 Kohlenstoff-The organic acid from which the metallic soap is derived preferably has at least 8 carbon atoms in the chain so that the metal soap in the poly-olefin is soluble and compatible with it. It was found that the organic monocarboxylic acids are very suitable that the carboxyl group on branched carbon chains with 8 to 20 carbon

atomen gebunden enthalten und die vorzugsweise wenigstens einen Alkylsubstituenten enthalten, der an das der Carboxylgruppe benachbarte Kohlenstoffatom gebunden ist. Derartige Säuren sind im Handel leicht erhältlich, und zwar sowohl als einzelne Verbindungen als auch als Mischungen verwandter Säuren, wie z.B. als Mischung verzweigter Fettsäuren, die 9 bis 11 Kohlenstoff atome enthalten.Atoms contain bonded and which preferably contain at least one alkyl substituent on the carbon atom adjacent to the carboxyl group is bonded. Such acids are commercially available readily available both as individual compounds and as mixtures of related ones Acids, such as a mixture of branched fatty acids containing 9 to 11 carbon atoms.
Das erfindungsgemäße Verfahren ist auf die Herstellung von Fasern und Fäden aus stereoregulären Polyolefinen, z.B. aus stereoregulärem PoIy-(4-methylpenten-l) oder isotaktischem Polypropylen geeignet.The inventive method is based on the production of fibers and threads from stereoregular Polyolefins, e.g. from stereoregular poly (4-methylpentene-1) or isotactic polypropylene.
Von den vielen Arten chemischer Verbindungen, die für die Stabilisierung von Poly-a-olefinen gegen Licht oder oxydativen Abbau vorgeschlagen wurden, haben vergleichsweise nur wenige eine weite Anwendung gefunden, z. B. Thiobisphenole, Dialkylester der Thiodialkansäuren, substituierte Phenylendiamine, Benzophenonderivate, Organophosphorverbindungen und die Kondensationsprodukte von Aldehyden und Phenolen oder deren Mischungen (s. »Atmospheric Oxydation and Antioxidants«, G. Scott, Elsevier, 1965).Of the many types of chemical compounds used for the stabilization of poly-a-olefins against Light or oxidative degradation have been suggested, comparatively few have wide application found, e.g. B. Thiobisphenols, dialkyl esters of thiodialkanoic acids, substituted phenylenediamines, Benzophenone derivatives, organophosphorus compounds and the condensation products of Aldehydes and phenols or their mixtures (see »Atmospheric Oxydation and Antioxidants«, G. Scott, Elsevier, 1965).
Es wurde festgestellt, daß Metallseifen von Fettsäuren mit linearen Kohlenstoffketten, wie Zinkstearat, die Wirkung einiger Stabilisatoren derart stören, daß die Stabilisatoren beinahe vollständig unwirksam werden.It has been found that metal soaps of fatty acids with linear carbon chains, such as zinc stearate, interfere with the action of some stabilizers in such a way that the stabilizers are almost completely become ineffective.
Damit die verbesserte Affinität gegen Farbstoffe vom obenerwähnten Typ einen angemessenen Wert aufweist, muß eine ausreichende Menge der erfindungsgemäß verwendeten Metallseifen dem Polyolefin beigemischt werden. Es wurde festgestellt, daß 1 bis 10%, vorzugsweise 2 bis 6%, bezogen auf das Polyolefingewicht, geeignete Mengen darstellen. Die Stabilisatorenmenge muß gleichfalls für eine angemessene Stabilisierung ausreichen. Es wurde festgestellt, daß 0,1 bis 5% Stabilisator oder Stabilisatorengemisch genügt. Die Zugabe der Metallseife und der geeigneten Stabilisierungssubstanzen zu dem Polyolefin kann unmittelbar vor dem Verformungsprozeß erfolgen oder bei jeder Verfahrensstufe während der Herstellung des Polyolefins beigegeben werden.So that the improved affinity for dyes of the above-mentioned type is an adequate value has, a sufficient amount of the metal soaps used in the invention must be the polyolefin be added. It has been found that 1 to 10%, preferably 2 to 6%, based on the Polyolefin weight, represent suitable amounts. The amount of stabilizer must also be adequate Stabilization is sufficient. It was found that 0.1 to 5% stabilizer or stabilizer mixture enough. The addition of the metal soap and the appropriate stabilizing substances to the Polyolefin can take place immediately before the deformation process or during each process step be added to the manufacture of the polyolefin.
In den folgenden Beispielen wird die Stabilität gegen oxydative Zerstörung (angegeben als Lebensdauer) durch Ermittlung der Zeit gemessen, die schmelzgesponnene Fäden brauchen bis sie spröde werden, wenn sie in einem Luftofen einer Temperatür von 140° C ausgesetzt werden. In diesen Beispielen sind Teile und Prozente jeweils als Gewichtsteile und Gewichtsprozente zu verstehen.In the following examples, the stability against oxidative destruction (given as service life) measured by determining the time it takes for melt-spun filaments to become brittle when exposed to 140 ° C in an air oven. In these examples parts and percentages are to be understood as parts and percentages by weight.
