Description

Die Erfindung betrifft ein trilobales, feinfibrilliges Filamentgarn mit einer Fadenviskosität RV von 40-55 und einer Festigkeit von 30-45 cN/tex, insbesondere als Vorlagegarn zum Texturieren, sowie ein Verfahren zur Herstellung desselben.The invention relates to a trilobal, fine-fibrillated filament yarn with a yarn viscosity RV of 40-55 and a strength of 30-45 cN / tex, in particular as a master yarn for texturing, and a method for producing the same.

Profilierte Polyhexamethylenadipamidgarne sind bekannt (US-A-4801503). Bei dem bekannten Garn handelt es sich um ein glattes Filament mit bandförmigem Fibrillenquerschnitt mit einem Einzeltiter von 2.8 dtex, welches wegen seiner hohen Biegefestigkeit als Spandexersatz zur Herstellung von Strümpfen geeignet ist. Der tiefe Biegemodul wird vor allem auf die besondere Profilierung zurückgeführt. Das bekannte Garn wird als sogenanntes Polyamid LOY-Garn zweistufig hergestellt.Profiled polyhexamethylene adipamide yarns are known (US-A-4801503). The known yarn is a smooth filament with a band-shaped fibril cross-section with a single titer of 2.8 dtex, which is suitable as a spandex substitute for the production of stockings due to its high flexural strength. The deep bending module is mainly attributed to the special profile. The well-known yarn is produced in two stages as a so-called polyamide LOY yarn.

Unter einem Polyamid LOY ist ein Filament zu verstehen, welches bei Spinn-Abzugsgeschwindigkeiten bis etwa 1800 m/min aufgewickelt wird; Polyamid POY ist durch Spinn-Abzugsgeschwindigkeiten zwischen 3700 und 5000 m/min erzeugt.A polyamide LOY is to be understood as a filament which is wound up at spinning take-off speeds of up to approximately 1800 m / min; Polyamide POY is produced by spinning take-off speeds between 3700 and 5000 m / min.

Aus der JP-A-58081609 sind trilobale ultrafeine Garne aus Polyester mit einem Einzeltiter < 1.5 dpf bekannt. Die bekannten Garne weisen extrem hohe Schmelzeviskositäten auf, dienen zur Herstellung von beispielsweise künstlichem Leder. Die Herstellung erfolgt bei Spinngeschwindigkeiten grösser gleich 2500 m/min. Sie sind für den textilen Einsatz in der Weberei ungeeignet.JP-A-58081609 discloses trilobal ultra-fine yarns made of polyester with a single titer <1.5 dpf. The known yarns have extremely high melt viscosities and are used to produce artificial leather, for example. Production takes place at spinning speeds greater than or equal to 2500 m / min. They are unsuitable for textile use in weaving.

Ein Nachteil von Polyamid LOY für den geplanten Einsatz des vorliegenden Garns ist vor allem in den niedrigen Spinngeschwindigkeiten zu sehen, welche eine wirtschaftliche Herstellung nicht gewährleistet. Ein weiterer Nachteil ist die schlechtere Weiterverarbeitung (Fadenbrüche) von Polyamid LOY bei hohen Geschwindigkeiten.A disadvantage of polyamide LOY for the planned use of the present yarn can be seen above all in the low spinning speeds, which do not guarantee economical production. Another disadvantage is the poorer processing (thread breaks) of polyamide LOY at high speeds.

Es ist auch bekannt, dass es bisher nicht gelungen ist, feinere, profilierte Filamente, mit ausreichender Anfärbehomogenität im textilen Flächengebilde mit annehmbarer Titerregelmässigkeit ( U%) herzustellen. Die Herstellung von profilierten Filamenten im Titerbereich von glatten Strumpfgarnen mit Feinheiten von dtex 22 f 8, d. h. einem Einzeltiter von etwa dtex 2.8 bereitet keine Schwierigkeiten .It is also known that so far it has not been possible to produce finer, profiled filaments with sufficient dye homogeneity in the textile fabric with an acceptable titer regularity (U%). The production of profiled filaments in the titer range of smooth hosiery yarns with finenesses of dtex 22 f 8, d. H. a single titer of around dtex 2.8 is no problem.

Hingegen bietet die Herstellung eines feinfibrilligen profilierten Vorlagegarnes aus Polyhexamethylenadipamid (Nylon 66) POY erhebliche Schwierigkeiten. Das mag daran liegen, dass ein runder Fibrillenquerschnitt energetisch einen Idealzustand darstellt, von welchem man sich beim Profilspinnen erheblich entfernt. Mit steigender Feinfibrilligkeit wird beim Schmelzspinnen der Fadenbildungsprozess instabiler. Dies äussert sich vor allem darin, dass die Titerregelmässigkeit stark abnimmt und am fertigen Flächengebilde eine ungleichmässige Anfärbbarkeit resultiert. Diese Nachteile treten verstärkt beim Schmelzspinnen von Polyamid-POY auf.On the other hand, the production of a fine-fibrillated profiled yarn from polyhexamethylene adipamide (nylon 66) POY presents considerable difficulties. This may be due to the fact that a round cross section of the fibril represents an ideal energy condition, from which one considerably moves away during profile spinning. With increasing fine fibrillation, the thread formation process becomes more unstable during melt spinning. This manifests itself above all in the fact that the titer regularity decreases sharply and that the finished fabric results in an uneven dyeability. These disadvantages are more common in melt spinning polyamide POY.

Die Fadenviskosität wird in bekannter Weise als relative Viskosität (RV) in Ameisensäure gemessen.The thread viscosity is measured in a known manner as relative viscosity (RV) in formic acid.

Zur Bestimmung der Farbgleichmässigkeit wird aus mehreren beliebigen Spinnwickeln eines Lots ein Strumpfabschnitt gestrickt. Der Strumpfabschnitt wird in einem Bad mit dem Farbstoff Alizarinlichtblau 4GL der Firma Sandoz AG, Basel in bekannter Weise angefärbt und nach dem Trocknen kolorimetrisch auf die unterschiedlichen Remissionen (Helligkeiten) der von den verschiedenen Spinnwickeln stammenden Abschnitte gemessen. Von den Remissionen wird in bekannter Weise der Variationskoeffizient berechnet.To determine the color uniformity, a stocking section is knitted from any number of spinning reels of a solder. The stocking section is in a bath with the dye Alizarin light blue 4GL from Sandoz AG, Basel stained in a known manner and, after drying, measured colorimetrically for the different remissions (brightnesses) of the sections originating from the different spinning reels. The coefficient of variation of the remissions is calculated in a known manner.

Aufgabe der Erfindung ist es, ein feines profiliertes Vorlagegarn zum Texturieren oder Nachverstrecken zur Verfügung zu stellen, welches vor allem in der Weberei für Kettfäden geeignet ist und die färberischen Nachteile der bekannten Profilfäden nicht aufweist.The object of the invention is to provide a fine profiled original yarn for texturing or post-stretching, which is particularly suitable for warp threads in the weaving mill and does not have the dyeing disadvantages of the known profile threads.

Eine weitere Aufgabe ist es, ein Filamentgarn zur Verfügung zu stellen, das im fertigen textilen Flächengebilde keinen als "speckig" bekannten Glanz, einen verbesserten sehr weichen Griff aufweist.Another object is to provide a filament yarn which in the finished textile fabric does not have a gloss known as "greasy" and has an improved, very soft feel.

Die Aufgabe wird mit einem Profilfaden erfindungsgemäss gelöst, durch einen Einzelfibrillentiter < 1,5 dtex, einer hohen Farbgleichmässigkeit (Variationskoeffizient) von < 2 und ein Breiten/Längenverhältnis B/L des Fibrillenquerschnitts von 0,5 bis 0,7.The object is achieved according to the invention with a profile thread, by means of a single fibril titer <1.5 dtex, a high color uniformity (coefficient of variation) of <2 and a width / length ratio B / L of the fibril cross section of 0.5 to 0.7.

Ein Profilfaden, mit einem Einzelfibrillentiter von < 1,5 dtex, zeigt in überraschender Weise keine sichtbaren Unregelmässigkeiten wie beispielsweise Streifigkeit im gefärbten Flächengebilde. Es ist erstmals gelungen, einen so feinen Fibrillentiter, mit einem POY-Ausgangsmaterial herzustellen, der eine Farbgleichmässigkeit mit einem Variationskoeffizienten von < 2 und einer Titerregelmässigkeit von Uster% < 1 aufweist. Auch das Breiten-/Längenverhältnis des Filamentquerschnitts von 0,5 bis 0,7, insbesondere um 0,6, ist für die textilen Anforderungen bezüglich Glanz und Griff besonders geeignet. Zur zahlenmässigen Erfassung der Profilausprägung dient das Verhältnis aus Breite und Länge B/L, bei trilobalen Fäden gemessen vom Beginn des Schenkels.A profile thread, with a single fibril titer of <1.5 dtex, surprisingly shows no visible irregularities, such as streakiness in the colored fabric. It was possible for the first time to produce such a fine fibril titer with a POY starting material that has a color uniformity with a coefficient of variation of <2 and a titer regularity of Uster% <1. The width / length ratio of the filament cross section from 0.5 to 0.7, in particular around 0.6, is also particularly suitable for the textile requirements with regard to gloss and feel. The ratio of width and Length B / L, measured from the beginning of the leg for trilobal threads.

Es ist besonders zweckmässig das Filamentgarn mit einem trilobalen Profil zu versehen. Im Einsatzgebiet Texturierung/Strumpf können aber auch Fäden mit einem allgemein flachen Profil verwendet werden.It is particularly useful to provide the filament yarn with a trilobal profile. In the field of texturing / stocking, threads with a generally flat profile can also be used.

Bei der Herstellung des profilierten Polyamid-Filamentgarns mit einer Festigkeit von 30-45 cN/tex, wird mit Spritzgeschwindigkeiten von 8-14 m/min, insbesondere von 8,5-10 m/min, bevorzugt 12m/min, gearbeitet. Sie tragen wesentlich zu einer verbesserten Garnsauberkeit bei.In the production of the profiled polyamide filament yarn with a strength of 30-45 cN / tex, spray speeds of 8-14 m / min, in particular 8.5-10 m / min, preferably 12m / min, are used. They contribute significantly to improved yarn cleanliness.
