Taschenfutterstoff Pocket lining
Beschreibungdescription
Die Erfindung betrifft ein Taschenfutterstoff, bestehend aus einem Mikrofilament-Vliesstoff mit Flächengewichten von 40 bis 200 g/m2 und einer Reißfestigkeit > 150 N.The invention relates to a pocket lining material, consisting of a microfilament nonwoven with a basis weight of 40 to 200 g / m 2 and a tensile strength of> 150 N.
In der Textilindustrie werden ganz unterschiedliche Anforderungen an die für die Herstellung von Hosen- und Jackentaschen eingesetzten Futterstoffe gestellt. Neben der Belastbarkeit, die sich in der Reißfestigkeit des eingesetzten Stoffes ausdrückt, sind gute Verarbeitbarkeit und je nach Anwendungszweck eine geringe Materialdicke bzw. ein gutes Wärmeisolationsvermögen von Interesse. Bisher werden als Taschenfutterstoffe aus unterschiedlichen Fasermischungen gewebte Stoffe eingesetzt, die aufgrund ihrer Webstruktur zum Ausfasern bzw. Ausfransen neigen und deshalb Gesäumt werden mußten. Gleichzeitig ist bei gewebten Stoffen hinsichtlich deren Belastbarkeit auch immer die Laufrichtung des Gewebes zu beachten.In the textile industry there are very different requirements for the lining materials used for the production of trouser and jacket pockets. In addition to the resilience, which is expressed in the tensile strength of the material used, good processability and, depending on the application, a low material thickness or good thermal insulation properties are of interest. So far, woven fabrics from different fiber mixtures have been used as pocket linings, which tend to fray or fray due to their weave structure and therefore had to be hemmed. At the same time, the direction of the weave must always be taken into account with regard to its resilience.
Die Erfindung hat sich die Aufgabe gestellt, preiswerte Taschenfutterstoffe, der eine Reißfestigkeit > 150 N besitzt sowie ein Verfahren zu deren Herstellung anzugeben.The object of the invention is to provide inexpensive pocket lining materials which have a tensile strength of> 150 N and a process for their production.
Erfindungsgemäß wird die Aufgabe durch einen Taschenfutterstoff gelöst, welcher aus einem Mikrofilament-Vliesstoff mit Flächengewichten von 40 bis 200 g/m2 sowie und einer Reißfestigkeit > 150 N besteht, wobei der Vliesstoff aus schmelzgesponnenen, verstreckten und unmittelbar zu einem Vlies abgelegten Mehrkomponenten-Endlosfilamenten mit einem Titer von 1 ,5 bis 5 dtex besteht und die Mehrkomponenten-Endlosfilamente gegebenenfalls nach einer Vorverfestigung zumindest zu 80 % zu Mikro-Endlosfilamenten mit einem Titer von 0,1 bis 0,8 dtex gesplittet und verfestigt sind. Die isotrope Fadenverteilung im Vliesstoff macht ein Säumen und die Beachtung der Maschinenlaufrichtung nicht erforderlich. Durch die endlos Filamente weist der Taschenfutterstoff kein Ausfasern auf. Eine chemische Ausrüstung ist nicht erforderlich.According to the invention, the object is achieved by a pocket lining material, which consists of a microfilament nonwoven fabric with basis weights of 40 to 200 g / m 2 and and a tensile strength> 150 N, the nonwoven fabric consisting of melt-spun, stretched and immediately deposited into a nonwoven multicomponent filaments with a titer of 1.5 to 5 dtex and the multicomponent filaments optionally after pre-consolidation at least 80% are split and solidified into continuous micro filaments with a titer of 0.1 to 0.8 dtex. The isotropic thread distribution in the nonwoven fabric does not require hemming and observing the machine direction. Due to the endless filaments, the pocket lining has no fraying. Chemical equipment is not required.
Vorzugsweise ist der Taschenfutterstoff einer, bei dem der Vliesstoff aus schmelzgesponnenen, aerodynamisch verstreckten und unmittelbar zu einem Vlies abgelegten Mehrkomponenten-Endlosfilamenten mit einem Titer von 1 ,5 bis 3 dtex besteht und die Mehrkomponenten-Endlosfilamente zumindest zu 80 % zu Mikro-Endlosfilamenten mit einem Titer von 0,1 bis 0,3 dtex gesplittet und verfestigt sind. . Die Taschenfutter weist eine isotrope Filamentverteilung im Vlies auf. Daher ist eine Berücksichtigung der Maschinenlaufrichtung beim Zuschnitt der Teile der Taschenfutter nicht erforderlich.The pocket lining material is preferably one in which the nonwoven fabric consists of melt-spun, aerodynamically stretched and immediately deposited multi-component continuous filaments with a titer of 1.5 to 3 dtex, and the multi-component continuous filaments at least 80% of micro-continuous filaments with one Titers of 0.1 to 0.3 dtex are split and solidified. , The pocket lining has an isotropic filament distribution in the fleece. It is therefore not necessary to take the machine direction into account when cutting the parts of the pocket lining.
Vorzugsweise ist der Taschenfutterstoff einer, bei dem das Mehrkomponenten- Endlosfilament ein Bikomponenten-Endlosfilament aus zwei inkompatiblen Polymeren, insbesondere einem Polyester und einem Polyamid, besteht.

Gleichzeitig ist die erfindungsgemäße Taschenfutter aufgrund der verwendeten Polymere und deren Filamentstruktur knitterarm, gut waschbar und schnell trocknend, d.h., pflegeleicht.The pocket lining material is preferably one in which the multicomponent continuous filament is a bicomponent continuous filament composed of two incompatible polymers, in particular a polyester and a polyamide. Such a bicomponent filament has good cleavage in micro filaments and brings about a favorable ratio of strength to basis weight.

Solche Segment-Anordnungen der inkompatiblen Polymeren im Mehrkomponenten-Endlosfilament haben sich als sehr gut spaltbar erwiesen. Die Taschenfutterstoffe besitzen ein sehr günstiges Verhältnis von Flächengewicht zum Isolationsvermögen, so daß sich insbesondere durch nachfolgende Behandlungsschritte wie Rauen oder Schleifen weiche und wärmende Innentaschen in Winterbekleidung herstellen lassen.The pocket lining material is preferably one in which the multicomponent continuous filaments have a cross section with an orange or “pie” have said multi-segment structure, the segments each alternately containing one of the two incompatible polymers. In addition to this orange-like multisegment structure of the multicomponent continuous filaments, a “side-by-side” (s / s) segment arrangement of the incompatible polymers in the multicomponent continuous filament is also possible, which is preferably used to produce crimped filaments. Such segment arrangements The incompatible polymers in the multicomponent continuous filament have proven to be very easy to split.The pocket lining materials have a very favorable ratio of basis weight to insulation capacity, so that soft and warming inner pockets in winter clothing can be produced in particular by subsequent treatment steps such as roughening or grinding.

Weiterhin können durch die Zusätze statische Aufladungen vermindert bzw. vermieden und die Feuchtigkeits-T ransporteigenschaften verbessert werden. Die Taschenfutterstoffe weisen sehr gute Pflegeeigenschaften hinsichtlich ihrer Waschbarkeit und einer geringen Trockenzeit auf.The pocket lining material is preferably also one in which at least one of the incompatible polymers forming the multi-component continuous filament is an additive, such as color pigments, permanently acting antistatic agents, fungicides, bactericides, acaricides and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 10% by weight , contains. Furthermore, the additives can reduce or avoid static charges and improve the moisture transport properties. The pocket lining materials have very good care properties with regard to their washability and a short drying time.

Vorteilhafterweise wird das Verfahren zur Herstellung der Taschenfutterstoff in der Weise durchgeführt, daß die Verfestigung und Splittung der Mehrkomponenten-Endlosfilamente dadurch erfolgt, daß der gegebenenfalls vorverfestigte Vliesstoff mindestens einmal auf jeder Seiten mit Hochdruck- Wasserstrahlen beaufschlagt wird. Der Taschenfutterstoff weist dadurch eine gute Oberfläche und einen Splittungsgrad der Mehrkomponenten- Endlosfilamente > 80 % auf.The process for producing the pocket lining material is advantageously carried out in such a way that the solidification and splitting of the multi-component continuous filaments takes place in that the optionally pre-consolidated nonwoven material is subjected to high-pressure water jets at least once on each side. The pocket lining material thus has a good surface and a degree of splitting of the multi-component continuous filaments> 80%.
