Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Polfaser-Vlieswirkstoffen auf Nähwirkmaschinen, die den zur Verarbeitung an der Arbeitsstelle der Nähwirkmaschine zugeführten Faserflor so gleichmäßig zu einer langen Florfalte ausbilden, dass nach dem Vermaschen zum Polfaser-Vlieswirkstoff dieser eine dieser eine Polhöhe in Ausführung von diagonal bis vertikal aus der Fasermaschenschicht abstehenden Faserteilen oder Faserteilschlingen von über 10 mm aufweist.The The invention relates to a device for the production of non-woven fabric fibers on stitchbonding machines, those for processing at the workplace evenly fed to the stitchbonding machine to form a long Florfalte that after meshing to Pol fiber nonwoven active this one of these one pole height from diagonal to vertical, from the fiber mesh layer protruding fiber parts or fiber slices of about 10 mm.
Derartige Polfaser-Vlieswirkstoffe mit Polhöhen von 10 bis 40 mm finden als voluminöse, dreidimensionale Vliesstoffe Einsatz zum Beispiel als Kaschiervliesstoffe, als Polstervliesstoffe, Filterstoffe, Isolierstoffe usw., als Komponenten für Textilverbundstoffe und als Substitute für Polyurethanschaumstoffe in verschiedenen Anwendungen.such Polfaser nonwoven active ingredients with pile heights of 10 to 40 mm find use as voluminous, three-dimensional nonwovens for example as laminating nonwovens, as upholstery nonwovens, filter fabrics, insulating materials etc., as components for textile composites and as substitutes for polyurethane foams in various applications.

Die Höhe dieser Polfalten wird vom Schwingweg der Einlegevorrichtung bzw. Bürste bestimmt, der an den derzeit bekannten Maschinen z. B. zwischen 8 und 35 mm eingestellt werden kann, sowie der entsprechend gewählten Zuführlänge des Faserflores für jede Maschenreihen-Ausbildung.The Height of these pole folds is the vibration path of the loading device or brush determined on the currently known machines z. B. between 8 and 35 mm can be adjusted, and the corresponding selected feed length of the fibrous web for every course formation.
Die mögliche Hubgröße von maximal 34 mm führt nicht zu der Ausbildung einer entsprechend hohen Polfalte, da die Bürste auf einem Kreisbogen schwingt und sich bereits vor dem oberen Totpunkt so weit von dem senkrecht von oben kommenden Faserflor entfernt, dass sie bei der Bewegung nach unten eine Strecke frei schwingt und so den Faserflor nicht erfassen kann. Aus diesem Grunde werden maximale Polhohen von ca. 7 bis 9 mm, je nach Eigenschaften des Faserflores erreicht.The possible stroke size of a maximum of 34 mm leads not to the formation of a correspondingly high pole fold, as the Brush on a circular arc swings and is already in front the top dead center so far from the vertically coming from above Fluff removes that while moving down a stretch vibrates freely and thus can not capture the batt. For this Basically, maximum pole heights of about 7 to 9 mm, depending on the characteristics reached the fibrous web.
Vliesstoffe,
die aus gefalteten Floren aufgebaut sind, wurden unter den Namen
Struto und Rotis bekannt. Schutzrechte die sich auf diese Anlagen und
Erzeugnisse beziehen sind z. B. von Krcma in CS Pat. –
Bei den vorgenannten Verfahren handelt es sich um Faltung von Faserfloren, die durch schwingende Kämme gefaltet und durch eine Stopfvorrichtung in einen Kanal eingetragen werden oder die durch eine Walze die mit schaufelförmigen Lamellen besetzt ist, bogenformig zu Polfalten geformt und gleichzeitig ebenfalls in einen Kanal gefördert werden. Dabei werden Höhen der Polfalten zwischen 20 und 50 mm gebildet. Der Zusammenhalt diesen Polschichten wird vorwiegend durch thermisch aktivierte Bindefasern gebildet, die bei der Faserflorbildung beigemischt wurden oder durch ein- oder beidseitig kaschierte textile Flächengebilde erreicht.at the aforesaid process is folding of fibrous webs, folded by swinging combs and by a stuffing device be entered in a channel or by a roller the is occupied by blade-shaped lamellae, bogenformig formed into creases and at the same time also conveyed into a channel become. In doing so, heights of the crease lines between 20 and 50 mm formed. The cohesion of these polar layers becomes predominantly formed by thermally activated binder fibers which are mixed in the formation of fibrous webs were or by one or both sides laminated textile fabrics reached.
Diese Methoden führen als Nebenwirkung bei der Verfestigung zu einer Versteifung des Vliesstoffes und zu Knickneigungen des entstehenden Verbundstoffes, die einen Einsatz als Kaschiervliesstoff z. B. bei Autositzbezügen nicht ermöglichen.These Methods lead to a side effect during solidification a stiffening of the nonwoven fabric and kink tendencies of the resulting composite, the one use as Kaschiervliesstoff z. B. in car seat covers not allow.

Der Kanal wird in seinem weiteren Verlauf so abgewinkelt, dass parallel zu den beiden Kanalwänden bekannte Filznadel einstechen können, die zusammen mit jeweils einem schwingenden Gegenhaltekamm eine Verfestigung der beiden Oberflächen mittels Faserpfropfen bewirken. Die Verfestigung erfolgt hier nicht mittels Fasermaschen. Inwieweit die vorgesehene längs zum Erzeugnis angeordneten Faserpfropfen eine ausreichende Verfestigung bewirken, ist zu bezweifeln. Eine Verbesserung gegenüber den bekannten Produkte Struto oder Rotis dürfte erreicht werden.Of the Channel is angled in its further course so that parallel Pierce the felt needle known to the two channel walls can, together with each a swinging counterhold comb a solidification of the two surfaces by means of Faserpfropfen cause. The solidification does not take place here by means of fiber meshes. To what extent the intended longitudinally arranged to the product Faserpfropfen cause sufficient solidification is to doubt. An improvement over the well-known Struto products or Rotis is likely to be achieved.
Aus den vorgenannten bekannten Bemühungen eine Lösung für voluminöse Polvliesstoffe zu finden geht hervor, dass marktseitig ein Interesse an einer solchen Lösung besteht. Mit den im Stand der Technik vorgestellten Verfahren bzw. Vorrichtungen sind bisher keine durchschlagenden Erfolge erzielt worden.Out the aforementioned known efforts a solution to find for voluminous nonwoven fabrics, that the market has an interest in such a solution consists. With the methods presented in the prior art or Devices have been achieved no resounding successes.
Nennenswerte Angebote die auch teilweise zu einer Produktion geführt haben sind mit den Verfahren Struto, Rotis bzw. WaveMaker und Abwandlungen bekannt. Allen diesen haften die in dem vorstehen beschriebenen Nachteile an.Noteworthy Offers that partly led to a production have with the procedures Struto, Rotis or WaveMaker and modifications known. All of these adhere to those described in the foregoing Disadvantages.
Der Erfindung liegt also die Aufgabe zu Grunde an der Arbeitsstelle der Nähwirkmaschine zur Ausformung hoher Polfalten durch eine erzwungene Auslenkung des Faserflores unter die Einlegevorrichtung (z. B. der Bürste) während deren Bewegung im Bereich des oberen Totpunktes eine große Florfalte auszubilden, die dann durch die Fasermaschenbildung einseitig eingebunden wird. Mittels dieser Vorformung der Florfalte durch die Anordnung und Wirkung des erfindungsgemäßen Faltenformers wird es möglich, größere Polhöhen zu bilden, als dies bei der bekannten Lösung der Fall ist, die sonst nur die aus der Eigenbewegung während der Bürstenschwingung entstehende Florfalte zur Polbildung nutzen kann.Of the Invention is therefore the task at the bottom of the job the stitchbonding machine for forming high pole folds a forced deflection of the batt under the loading device (eg the brush) during its movement in the area of the top dead center to form a large Florfalte which is then integrated by the fiber mesh formation on one side. By means of this preforming of Florfalte by the arrangement and Effect of the inventive folding is it possible to get bigger pile heights to form, as is the case with the known solution, otherwise only from the proper movement during the brush vibration can use resulting Florfalte for Polbildung.
In einer Weiterbildung der Erfindung ist, dass die Düse den Gasstrom zur Faserflorbewegung ständig aufrecht erhält und dadurch bei geeigneter Wahl der Faserflorliefergeschwindigkeit der voreilend gelieferte Faserflor unter der entstehenden Anspannung über die Bürste gleitet und so die angestrebte größere Florfalte entsteht.In a development of the invention is that the nozzle the Maintains gas flow to the bobbin movement constantly upright and thereby with a suitable choice of the Faserflorliefergeschwindigkeit the leading delivered batt under the resulting tension the brush slides and so the aimed larger Florfalte arises.
Eine andere Weiterbildung der Erfindung beinhaltet statt der Vorlage eines Faserflores zur Arbeitsstelle die Vorlage eines Filamentflores, hergestellt nach einer speziellen Spinnvliestechnologie bzw. die Vorlage eines zum Vlies quergelegten Faserflores.A Another embodiment of the invention includes instead of the template a fibrous web to the workstation the presentation of a filament pile, manufactured according to a special spunbonding technology or the Template of a non-woven transverse fibrous batt.
