Aus
dem Dokument
Das Dokument WO 01/53587 A1 beschreibt ein Verfahren zur Herstellung von hochdauerhaften, Flüssigkeitsstrahlen verfestigten Vliesstoffen, deren Ausgangsflor aus einer Mischung thermoplastisch schmelzbarer Fasern und Basisfasern besteht, die zu einem Ausgangsflor konsolidiert, durch Einwirkung von Flüssigkeitsstrahlen zu einem Vliesstoff verfestigt sowie durch Benutzung einer dreidimensionalen Abbild-Übertragungs-Vorrichtung zur Bildung einer dreidimensionalen räumlichen Anordnung des Vliesstoffes geformt und anschließend durch Temperaturbehandlung des in dreidimensionaler räumlichen Anordnung geformten Vliesstoffes auf die Schmelztemperatur der schmelzbaren Fasern durch Zusammenbinden der Fasermischung in der dreidimensionalen räumlichen Anordnung fixiert wird.The Document WO 01/53587 A1 describes a process for the preparation of high-lasting, liquid jets solidified nonwovens whose Ausgangsflor of a mixture thermoplastic meltable fibers and base fibers, the consolidated to a parent pile, by the action of liquid jets solidified into a nonwoven fabric and by using a three-dimensional image transfer device to form a three-dimensional spatial arrangement of the nonwoven fabric shaped and then by temperature treatment of in three-dimensional spatial Arrangement shaped nonwoven fabric on the melting temperature of the fusible Fibers by tying the fiber mixture in the three-dimensional spatial Arrangement is fixed.
Weiterhin ist aus dem Dokument US 2002/0034914 A1 ein Verfahren zur Herstellung eines Flammschutz-Vliesstoffes bekannt, bei dem ein Flor aus schwer entflammbaren Polyesterfasern auf einer dreidimensionalen Abbild-Übertragungs-Vorrichtung durch Einwirkung von Flüssigkeitsstrahlen zu einem Vliesstoff verfestigt sowie durch Aufbringen und Härten eines Bindemittels in der dreidimensionalen räumlichen Anordnung fixiert wird.Farther is from the document US 2002/0034914 A1 a method for manufacturing a flame retardant nonwoven known in which a pile of heavy flammable polyester fibers on a three-dimensional image transmission device Influence of liquid jets too solidified a nonwoven fabric and by applying and curing a Binder fixed in the three-dimensional spatial arrangement becomes.
Auch das Dokument US 2002/0004348 A1 beschreibt einen mechanisch verfestigten Vliesstoff mit thermischen Schutzeigenschaften, bei dem ein Ausgangsflor aus Melamin- und Aramidfasern mit Hilfe von Hochdruckwasserstrahlen verfestigt, auf eine dreidimensionale Abbild-Übertragungs-Vorrichtung aufgebracht und durch erneute Einwirkung von Hochdruck-Flüssigkeitsstrahlen das dreidimensionale Abbild auf den Vliesstoff übertragen wird.Also The document US 2002/0004348 A1 describes a mechanically solidified Nonwoven fabric with thermal protection properties, in which a Ausgangsflor made of melamine and aramid fibers by means of high-pressure water jets solidified, applied to a three-dimensional image transfer device and by re-acting high-pressure liquid jets the three-dimensional Transfer image to the nonwoven fabric becomes.
Die Erfindung hat sich die Aufgabe gestellt,
- a) ein einfaches Verfahren zur Herstellung eines dreidimensional geformten Vliesstoffes,
- a) eine Vorrichtung zur Benutzung in dem Verfahren,
- a) einen danach erhaltenen dreidimensional geformter Vliesstoff und
- a) dessen Verwendung anzugeben.
- a) a simple process for producing a three-dimensionally shaped nonwoven fabric,
- a) a device for use in the method,
- a) a subsequently obtained three-dimensionally shaped nonwoven fabric and
- a) indicate its use.
Erfindungsgemäß wird die Aufgabe a) dadurch gelöst, dass ein mechanisch verfestigter Vliesstoff durch einseitige Behandlung mit Hochdruck-Fluidstrahlen im Druckbereich von 40 bis 275 Pa auf einem Lochsieb/-blech mit einer Lochgröße von 0,5 bis 10 mesh (entsprechend der Formel mesh2*0,181 = Löcher/cm2) in die z-Richtung verformt wird. Dabei können Stapelfasern mit einer Faserlänge 38–60 mm, endlos Filamente oder Mischungen aus Langfasern und Filamenten eingesetzt werden.According to the invention, the object a) is achieved in that a mechanically consolidated nonwoven fabric by one-sided treatment with high-pressure fluid jets in the pressure range of 40 to 275 Pa on a perforated screen / sheet with a hole size of 0.5 to 10 mesh (corresponding to the formula mesh 2 * 0.181 = holes / cm 2 ) is deformed in the z-direction. Staple fibers with a fiber length of 38-60 mm, endless filaments or mixtures of long fibers and filaments can be used.
Vorteilhafterweise wird ein gekrempelter Faserflor an mindestens zwei Wasserstrahl-Verfestigungsvorrichtungen vorverfestigt. Der gebildete, noch feuchter Vliesstoff wird anschließend durch einseitige Behandlung mit Hochdruck-Fluidstrahlen im Druckbereich von 80 bis 275 Pa auf einem Lochsieb/-blech mit einer Lochgröße von 0,5 bis 10 mesh verformt. Es werden dazu Vliesstoffe mit einem Flächengewicht zwischen 30 und 300 g/m2 und einer Dicke zwischen 0,5 mm und 3 mm eingesetzt. Der Vliesstoff kann 5 bis 50 Gewichtsprozent (Gew.-%) Bindefasern enthalten. Dabei wird der Vliesstoff vorzugsweise nach der Formung im Temperaturbereich von 170 bis 260 °C getrocknet und thermofixiert/thermostabilisiert. Der Vliesstoff wird durch das erfindungsgemäße Verfahren zwischen 0,5 und bis zur 5fachen seiner Ausgangsdicke in z-Richtung verformt.Advantageously, a carded fibrous web is preconsolidated on at least two water jet solidification devices. The formed, still wet nonwoven fabric is then formed by one-side treatment with high-pressure fluid jets in the pressure range of 80 to 275 Pa on a perforated screen / sheet with a hole size of 0.5 to 10 mesh deformed. For this purpose, nonwovens having a basis weight between 30 and 300 g / m 2 and a thickness between 0.5 mm and 3 mm are used. The nonwoven fabric may contain 5 to 50 weight percent (wt.%) Binder fibers. In this case, the nonwoven fabric is preferably dried after the molding in the temperature range of 170 to 260 ° C and heat-set / thermostabilized. The nonwoven fabric is deformed by the inventive method between 0.5 and up to 5 times its initial thickness in the z direction.
Die Erhebungen werden dabei, durch mäßigen Verzug, ausgeformt.The Surveys are thereby, by moderate delay, formed.
Überraschender Weise werden trotz der nur einseitigen Flüssigkeitsstrahlenbehandlung keine Löcher in dem Vliesstoff geformt, wie sie auf Siebtrommeln mit einer Maschenweite >20 mesh oder größer entstehen, sondern die Faserstruktur wird in der erfindungsgemäßen Lochstruktur gleichmäßig eingeformt. Die erhaltene dreidimensionale Struktur des Vliesstoffes ist erstaunlich stabil und gegen Kompression inert. Zur besseren Stabilisierung der dreidimensionalen Struktur des Vliesstoffes ist es vorteilhaft Bindefaser zuzugeben. Dadurch wird die Druckempfindlichkeit der Noppen wesentlich herabgesetzt. Der Anteil der Bindefaser (homofil) kann dabei für Anwendungen, die als Flammschutzmaterial eingesetzt werden, zwischen 5–50 Gew.-% variieren. Bei Verwendung von Heterofil-Bindefaser kann der Anteil an Heterofil-Bindefaser je nach Festigkeitsanforderungen > 50 Gew.-% betragen. Bei Anwendungen bei denen die Temperaturbelastbarkeit keine Rolle spielt, kann der Anteil bis zu 100% Heterofil-Fasern betragen. Die Menge der Bindefaser geht in die Haptik ein, wobei eine Korrelation zwischen dem Anteil der Bindefasern an der eingesetzten Fasermischung und der Steifigkeit des erhaltenen Vliesstoffes in der Weise besteht, dass je mehr Bindefasern in der eingesetzten Fasermischung vorhanden sind desto steifer wird der resultierende Vliesstoff. Für Nichtbekleidungs-Anwendungen kann dieses ein Vorteil sein.Surprisingly, in spite of the one-sided liquid jet treatment, no holes are formed in the nonwoven fabric, as they are produced on sieve drums with a mesh size> 20 mesh or larger, but the fiber structure is uniformly formed in the hole structure according to the invention. The resulting three-dimensional structure of the nonwoven fabric is surprisingly stable and inert to compression. For better stabilization of the three-dimensional structure of the nonwoven fabric, it is advantageous to add binder fiber. As a result, the pressure sensitivity of the knobs is significantly reduced. The proportion of binder fiber (homofil) can vary between 5-50 wt .-% for applications that are used as a flame retardant material. If heterofil binding fiber is used, the proportion of heterofil binding fiber can be> 50% by weight, depending on the strength requirements. For applications in which the temperature load capacity is irrelevant, the proportion can be up to 100% heterofil fibers. The amount of binding fiber enters the haptic, wherein there is a correlation between the proportion of binding fibers in the fiber mixture used and the stiffness of the resulting nonwoven fabric in such a way that the more binder fibers present in the fiber mixture used, the stiffer the resulting nonwoven fabric. For non-apparel applications this can be an advantage.
Erfindungsgemäß wird die Aufgabe b) dadurch gelöst, dass sie ein Lochblech mit einer Dicke von 0,5–10mm, bevorzugt 1,0 bis 3,0 mm, umfasst, welches Löcher aufweist, deren größte Ausdehnung 1 bis 12,5 mm ist und bei denen die Stegbreite zwischen den einzelnen Löchern 1,0 bis 12,5 mm beträgt. Die Höhe der Erhebungen (Bumper) beträgt je nach Blechdicke und in Abhängigkeit von der Dicke des Ausgangsmaterials 50–500 % oder 0,5–10mm, bevorzugt 1,0–3,0 mm. Die Bumperhöhe kann dabei je nach Faserlänge, maximal ca. 2 × 1/6-Länge der kürzesten eingesetzten Fasern betragen, ohne dass es zu signifikanten Festigkeitsverlusten kommt. Die minimale Stegbreite, ohne dass es zu signifikanten Festigkeitsverlusten kommt, beträgt etwa 2 × 1/6-Länge der kürzesten eingesetzten Fasern.According to the invention Problem b) solved by that it is a perforated plate with a thickness of 0.5-10mm, preferably 1.0 to 3.0 mm, which includes holes has, whose largest dimension is 1 is up to 12.5 mm and where the web width between the individual holes 1.0 to 12.5 mm. The height the bumps (bumper) is depending on sheet thickness and depending from the thickness of the starting material 50-500% or 0.5-10mm, preferred 1.0-3.0 mm. The bumper height depending on the fiber length, maximum about 2 × 1/6-length of the shortest used without significant loss of strength comes. The minimum web width, without significant strength losses comes, amounts about 2x1 / 6-length of the shortest used fibers.
Das Verhältnis von Stegfläche zu Noppenfläche kann dabei im Bereich von Stegfläche: 80–20 % zu Noppenfläche: 20–80 % variieren.The relationship from bridge surface to nub surface can in the area of web area: 80-20 % to nub surface: 20-80 % vary.
Dabei ist kein Rundloch absolut notwendig, sondern auch ovale oder multilobale Löcher. Auch rechteckige, rautenförmige u.ä. Lochformen sind einsetzbar, so lange die größte Diagonale im Loch 1/3 der Länge der kürzesten eingesetzten Fasern nicht überschreitet.there No round hole is absolutely necessary, but also oval or multilobal Holes. Also rectangular, diamond-shaped etc. hole shapes are usable, as long as the largest diagonal in the hole 1/3 of the length the shortest fibers used.
Die
Anordnung der Gitterpunkte wird wie folgt gewählt:
Erfindungsgemäß wird die Aufgabe c) dadurch gelöst, dass er auf einer Hauptseite Erhebungen und auf der entgegengesetzten Hauptseite analog angeordnete Vertiefungen aufweist.According to the invention Problem c) solved by that he surveys on one main page and on the opposite Main side has analog arranged recesses.
Die Erhebungen können zwischen 0,5 und bis zum 5fachen der Ausgangsdicke des Vliesstoffes betragen.The Surveys can be between 0.5 and up to 5 times the initial thickness of the nonwoven fabric.
Vorzugsweise werden als Fasern für den Vliesstoff solche verwendet, dass er mindestens eine der synthetischen, flammhemmenden Fasern ausgewählt aus der Gruppe m-Aramid-, p-Aramid-, Melaminharz-, Polyamidimid-, Polyimid-, Polybenzimidazol-, Silizium enthaltende Zellulose-Regenerat- und/oder Preoxfasern enthält.Preferably be considered as fibers for the nonwoven fabric used such that it contains at least one of the synthetic, flame retardant fibers selected from the group m-aramid, p-aramid, melamine resin, polyamide-imide, Polyimide, polybenzimidazole, silicon-containing cellulose regenerate and / or Preoxfasern contains.
Besonders bevorzugt für die Verwendung in Flammschutzmaterialien ist, dass auf der Vertiefungen aufweisenden Seite eine dampfdurchlässige, semipermeable Folie oder Membran aufgebracht ist.Especially preferred for The use in flame retardant materials is that on the wells having a vapor-permeable, semipermeable film side or membrane is applied.
Vorzugsweise erfolgt eine Verwendung des 3-dimensional geformten Vliesstoffs als thermisches Isolationsmaterial in Feuerwehrschutzbekleidungen.Preferably a use of the 3-dimensionally shaped nonwoven fabric as a thermal insulation material in fire protective clothing.
Weiterhin kann der 3-dimensional geformte Vliesstoff als Verstärkungsmaterial in Verbundstoffen eingesetzt werden.Farther can the 3-dimensionally shaped nonwoven fabric as a reinforcing material be used in composites.
Die Vorteile des erfindungsgemäß erhaltenen Vliesstoffes sind: Bei gleichem Gewicht höheres Volumens des Produktes, dass heißt, bei der thermischen Isolierung höhere Isolationswirkung durch mehr Lufteinschluss.The Advantages of the invention obtained Nonwoven fabrics are: For the same weight of higher volume of the product, that means, higher in thermal insulation Insulation effect through more air entrapment.
Bei der Verwendung als Flammschutzmaterial (Fireblocker) wird eine sehr gute thermische Isolierung bei leichten Gewichten im Vergleich zu Nadelvliesstoffen für den gleichen Einsatz erreicht, dass heißt, eine zusätzliche Steigerung der Isolationswirkung.at The use as flame retardant (Fireblocker) will be a very good thermal insulation at light weights compared to Needle nonwovens for achieved the same use, that is, an additional Increase the insulation effect.
