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 thread viscosity RV of 40-55 and a strength of 30-45 cN / tex, especially as a master yarn for texturing, as well as a method for manufacturing thereof.

Profilierte Polyhexamethylenadipamidgame sind bekannt (US-A-4801503). Bei dem bekannten Gam handelt es sich um ein glattes Filament mit bandförmigem Fibrillenquerschnitt mit einem Einzeititer 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 Gam wird als sogenanntes Polyamid LOY-Gam zweistufig hergestellt.Profiled polyhexamethylene adipamide games are known (US-A-4801503). With the well-known Gam it is a smooth filament with ribbon-shaped Fibril cross-section with a one-time titer of 2.8 dtex, which because of its high flexural strength as Spandex replacement suitable for the production of stockings is. The deep bending module is mainly due to the special Profiling traced. The well-known gam becomes a so-called polyamide LOY-Gam in two stages manufactured.

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 a filament which at spinning take-off speeds is wound up to about 1800 m / min; Polyamide POY is between by spinning take-off speeds 3700 and 5000 m / min generated.

Aus der JP-A-58081609 sind trilobale ultrafeine Game 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 are trilobal ultrafine Game made of polyester with a single titer <1.5 dpf known. The known yarns are extremely high Melt viscosities serve for the production of for example artificial leather. The production takes place at spinning speeds greater than or equal to 2500 m / min. They are for textile use in weaving not suitable.

Ein Nachteil von Polyamid LOY für den geplanten Einsatz des vorliegenden Gams 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 one Use of the present chamois is mainly in the low spinning speeds to see which one economic production not guaranteed. On Another disadvantage is the poorer processing (Thread breaks) of polyamide LOY at high speeds.

Aus der WO 91/19839 ist ein Verfahren zur Herstellung eines trilobalen Polyamidfilamentgarn bekannt.A method is known from WO 91/19839 for the production of a trilobal polyamide filament yarn known.

Nach Beispiel 6 (S69), wird der Faden mit einer Aufspulgeschwindigkeit von 3909 mpm aufgewickelt.According to example 6 (S69), the thread with a winding speed wound up from 3909 mpm.

Das Garn wird aus einem Polyamid 6.6 mit einer RV ron ∼50 hergestellt. Der erhaltene Faden weist einen Titer von 55/17 den auf.The yarn is made from a polyamide 6.6 made with a RV ron ∼50. The obtained thread has a titer of 55/17 on.

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 Strumpfgamen 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 successful is, finer, profiled filaments, with sufficient coloring homogeneity in the textile fabric with acceptable Establish titer regularity (U%). The Production of profiled filaments in the titer range of smooth hosiery with subtleties of dtex 22 f 8, d. H. a single titer of about dtex 2.8 does not Trouble.

Hingegen bietet die Herstellung eines feinfibrilligen profilierten Vorlagegarnes aus Polyhexametliylenadipamid (Nylon 66) POY erhebliche Schwierigkeiten. Das mag daran liegen, dass ein runder Fibrillenquersehnitt energetisch einen Idealzustand darstellt, von welchem man sich beim Profifspinnen erheblich entfemt. Mit steigender Feinfibrilfigkeit wird beim Schmelzspinnen der Fadenbildungsprozess instabiler. Dies äussert sich vor allem darin, dass die Trterregelmässigkeit stark abnimmt und am fertigen Flächengebilde eine ungleichmässige Anfärbbarkeit resultiert. Diese Nachteile treten verstärkt beim Schmelzspinnen von Polyamid-POY auf.In contrast, the production of a fine fibrillated profiled master yarn made of polyhexamethylene adipamide (Nylon 66) POY considerable difficulty. The may be due to the fact that a round cross section of the fibril energetically represents an ideal state of which one strays away considerably in professional spinning. With increasing Fine fibrility is the result of melt spinning Thread formation process more unstable. This manifests itself all in the fact that the regularity of the treadle decreases strongly and an uneven one on the finished fabric Dyeability results. These disadvantages occur reinforced when melt spinning polyamide POY.

Die Fadenviskosität wird in bekannter Weise als relative Viskosität (RV).in Ameisensäure gemessen.The thread viscosity is known in a known manner as relative Viscosity (RV) measured 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, several arbitrary spinning reels of a solder Stocking section knitted. The stocking section is in a bath with the 4GL alizarin light blue dye Sandoz AG, Basel stained in a known manner and after drying colorimetrically on the different Remissions (brightness) of the different sections originating from spinning reels measured. Of the remissions is known in Way the coefficient of variation is calculated.

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 a fine profiled Original yarn for texturing or post-stretching To make available, especially in the weaving mill is suitable for warp threads and the dyeing disadvantages does not have 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 task is to use a filament yarn To provide that in the finished textile fabric no gloss known as "greasy", one 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 solved by a single fibril titer <1.5 dtex, high color uniformity (coefficient of variation) of <2 and a width / length ratio B / L of the fibril cross section from 0.5 to 0.7.

Ein Profilfaden, mit einem Einzelfibrillentiter von < 1,5 dtex, zeigt in überraschender Weise keine sichtbären Unregefmässigkeiten 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 bears Irregularities such as streakiness in the colored fabric. For the first time such a fine fibril titer, with a POY starting material produce a color uniformity with a coefficient of variation of <2 and a titer regularity of Uster% <1. Also the width / length ratio of the filament cross section of 0.5 up to 0.7, especially around 0.6, is for the textile requirements particularly suitable in terms of gloss and grip. For numerical recording of the profile characteristics serves the ratio of width and length B / L, at trilobal threads measured from the beginning of the leg.

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.Filament yarn is particularly useful to be provided with a trilobal profile. In the field of application Texturing / stocking can also be made with threads generally flat profile can 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 Gamsauberkeit bei.In the production of the profiled polyamide filament yarn with a strength of 30-45 cN / tex with spray speeds of 8-14 m / min, in particular of 8.5-10 m / min, preferably 12m / min. They contribute significantly to an improved chamois cleanliness at.
