Description

Es ist bekannt, zur Herstellung eines Wirrfaservliesstoffes kurze Längen von Fasern zu einem Faservlies zusammenzufassen. So wird beispielsweise in der USA.-Patentschrift 2 920 679 ein Verfahren zur Herstellung eines Faservlieses beschrieben, bei dem die Fasern in einem elektrostatischen Feld aufgeladen und dann zu einem Vlies abgelegt werden, indem die aufgeladenen Fasern einer elektrischen Ladung entgegengesetzter Polarität ausgesetzt werden. Die so abgelegten Fasern können dann durch Aufbringen eines durch Wärmeeinwirkung klebrig werdenden Bindemittels zu einem Wirrfaservliesstoff gebunden werden.It is known to produce a tangled nonwoven fabric short lengths of fibers to a Summarize fiber fleece. For example, U.S. Patent 2,920,679 discloses a method for the production of a fiber fleece described in which the fibers are charged in an electrostatic field and then deposited into a fleece by the charged fibers of an electrical Charge of opposite polarity. The fibers deposited in this way can then pass through Application of a binding agent that becomes tacky due to the action of heat to form a random fiber nonwoven be bound.

Es sind auch verschiedene Verfahren vorgeschlagen worden zum innigen Verbinden der Fasern eines Faservlieses, um einen Wirrfaservliesstoff mit einem gewissen Grad der Festigkeit zu ergeben. So beschreibt beispielsweise die französische Patentschrift 1 108 826 einen Wirrfaservliesstoff, der dadurch verfestigt worden ist, daß eine Kräuselung oder Schrumpfung von potentiell schrumpfbaren oder kräuselbaren Fasern in dem Faservlies herbeigeführt wird. Solche Fasern können beispielsweise potentiell kräuselbare zusammengesetzte oder Heterofasern sein, wie sie in der USA.-Patentschrift 3 039 524 beschrieben sind. Der Charakter des Wirrfaservliesstoffes wird hierdurch jedoch grundsätzlich geändert, indem der Vliesstoff an sich verfestigt und versteift wird, was in vielen Fällen nicht erwünscht ist.Various methods have also been proposed for intimately joining the fibers of a Nonwoven fabric to give a tangled nonwoven fabric with a certain degree of strength. So describes For example, the French patent 1 108 826 a random fiber nonwoven fabric, which thereby has been solidified that crimp or shrinkage of potentially shrinkable or is brought about crimpable fibers in the nonwoven fabric. Such fibers can, for example, potentially be crimpable composite or hetero fibers such as those disclosed in U.S. Patent 3,039,524 are described. However, this fundamentally changes the character of the random fiber nonwoven, by consolidating and stiffening the nonwoven itself, which in many cases is undesirable.

Die Verwendung von chemischen Bindemitteln für die Fasern ist ebenfalls nicht in allen Fällen geeignet, da auch hierdurch die Eigenschaften des endgültigen Textüproduktes grundsätzlich verändert werden. Solche Bindemittel verteilen sich nämlich durch das ganze Faservlies hindurch, wodurch das Endprodukt einen harten Griff erhält und steif wird. In ähnlicher Weise wird auch mit Fasern, die in situ eine Kräuselung entwickeln, der Charakter der Fasern und daher auch des Textilproduktes bei der nachfolgenden Bindebehandlung grundlegend verändert, so daß die Eigenschaften des endgültigen Textilproduktes nicht voraussehbar sind. Es besteht daher das dringende Bedürfnis nach einem Verfahren zur Herstellung eines Wirrfaservliesstoffes, bei dem die physikalischen Eigenschaften des Faservlieses nicht grundlegend verändert werden, bis auf die, daß eine Erhöhung der Reißfestigkeit derselben herbeigeführt wird.The use of chemical binders for the fibers is also not in all cases suitable as this also fundamentally changes the properties of the final textured product will. Such binders distribute themselves through the entire fiber fleece, whereby the End product gets a hard grip and becomes stiff. Similarly, it is also done with fibers that are in situ develop a curl, the character of the fibers and therefore also of the textile product fundamentally changed during the subsequent binding treatment, so that the properties of the final textile product cannot be foreseen. It exists hence the urgent need for a process for producing a tangled fiber nonwoven fabric which the physical properties of the fiber fleece are not fundamentally changed, except for that an increase in the tensile strength thereof is brought about.

ίο Die Erfindung betrifft nunmehr ein Verfahren zur Herstellung eines Wirrfaservliesstoffes, bei dem in das lose Faservlies ein bestimmter Anteil an kurzen Bindefasern eingebracht wird und durch Auslösung der Kräuselung der Bindefasern eine Vliesverfestigung erreicht wird. Das Neue der Erfindung besteht hierbei darin, daß als Bindefasern potentiell kräuselbare, auf eine Länge von nicht mehr als 6,4 mm geschnittene Heterofäden mit einer potentiell klebfähigen Komponente verwendet werden und diese unter1 Einwirkung von elektrostatischen Kräften in das Faservlies eingearbeitet werden, daß dann das Vlies noch unter Einwirkung des elektrostatischen Feldes mit einer isolierten Walze gewalzt wird, anschließend eine Behandlung zwecks Kräuselung der Fasern erfolgt und die potentiell klebfähige Komponente der Bindefasern durch die gleiche oder eine nachfolgende Behandlung klebfähig gemacht wird.The invention now relates to a method for the production of a random fiber nonwoven fabric, in which a certain proportion of short binding fibers is introduced into the loose fiber nonwoven fabric and a nonwoven bonding is achieved by releasing the crimping of the binding fibers. The novelty of the invention here is that are no longer used as binder fibers potentially crimpable to a length of a 6.4 mm cut hetero threads with a potentially tacky component, and these are incorporated under 1 the action of electrostatic forces in the fiber web, that then the fleece is still rolled under the action of the electrostatic field with an insulated roller, then a treatment for the purpose of crimping the fibers is carried out and the potentially adhesive component of the binding fibers is made adhesive by the same or a subsequent treatment.

Die Bindefasern, weiche nach der Einwirkung durch das elektrostatische Feld und Behandlung mit der isolierten Walze noch nicht ausreichend in das Faservlies eingedrungen sind, können durch einen Vakuumextraktor von dem Faservlies entfernt werden, bevor dieses weiterbehandelt wird.The binding fibers soften after exposure to the electrostatic field and treatment with of the insulated roller have not yet penetrated sufficiently into the nonwoven fabric, can through a Vacuum extractor must be removed from the nonwoven fabric before this is further treated.

Die Festigkeit des nach der Erfindung hergestellten Wirrfaservliesstoffes kann noch dadurch erhöht werden, daß die Bindefasern von beiden Seiten des Faservlieses in dieses eingearbeitet werden.The strength of the tangled fiber nonwoven fabric produced according to the invention can be increased as a result that the binding fibers are incorporated into the nonwoven from both sides.

Die Erfindung wird nun an Hand der folgenden Beispiele näher erläutert.The invention will now be explained in more detail with reference to the following examples.

Ein kardiertes offenes Faservlies aus Polyhexamethylenadipamidstapelfasern von 38 mm Länge, welches ein Gewicht von 113,4g je 0,836 m- hat, wird auf die geerdete Arbeitsfläche einer herkömmlichen Flockierungsvorrichtung aufgebracht, und zwar unter einen Bindefasern enthaltenden Behälter, welcher ein Sieb und eine Bürste aufweist, die von einer Hochspannungsquelle von 110 kV aufgeladen wird. Die Vorrichtung ist weiterhin mit einer Walze und einem Vakuumextraktor versehen. Die Bindefasern bestehen bei diesem Versuch aus Stapelfasern von 3 mm Länge, die aus Heterofäden geschnitten sind, welche sich aus Nylon-66 und Nylon-66/6 (80/20) Mischpolymerbestandteilen zusammensetzen, die in einem Seite-an-Seite-Verhältnis vorliegen.A carded open fiber fleece made from polyhexamethylene adipamide staple fibers 38 mm long, which has a weight of 113.4 g per 0.836 m, is applied to the grounded work surface of a conventional flocculating device, and although under a container containing binding fibers, which has a sieve and a brush, which of a high voltage source of 110 kV is charged. The device is still with a roller and a vacuum extractor. In this experiment, the binding fibers consist of staple fibers 3 mm long cut from hetero threads consisting of nylon-66 and nylon-66/6 (80/20) composed of interpolymer ingredients that are in a side-by-side ratio.

Die Bindefasern werden dem Sieb zugeführt, durch die Bürsten gleichmäßig verteilt, in das zwisehen dem aufgeladenen Behälter und der geerdeten Arbeitsfläche elektrische Spannungsfeld fallengelassen und in das Faservlies geschleudert.The binding fibers are fed to the sieve, distributed evenly by the brushes, into the splice the charged container and the earthed work surface are released from the electrical voltage field and thrown into the non-woven fabric.

Die Bahn wird dann unter Verwendung einer isolierten Walze gewalzt, während sie sich unter dem Einfluß des elektrischen Feldes befindet, um die Fasern noch weiter in die Bahn eindringen zu lassen. Bindefasern, die hierbei nicht in die Faservliesbahn eingedrungen sind, werden mit Hilfe des Vakuum-The web is then rolled using an insulated roller while it is under the Influence of the electric field is to allow the fibers to penetrate even further into the web. Binding fibers that have not penetrated the nonwoven web are removed with the help of the vacuum

extraktors entfernt. Eine Prüfung des Wirrfaservliesstoffes bei dieser Verfahrensstufe zeigt, daß die Bindefasern innerhalb des Faservlieses in einer Richtung orientiert sind, die praktisch senkrecht zur Ebene der Bahn verläuft.extractor removed. An examination of the random fiber nonwoven fabric at this stage of the process shows that the Binding fibers are oriented within the nonwoven fabric in a direction that is practically perpendicular to Level of the train runs.

Die Faservliesbahn wird 3 Minuten in siedendes Wasser getaucht, um die Bindefasern zu kräuseln und in dem Faservlies zu verschlingen. Die gekräuselten Bindefasern besitzen eine Kräuselungsfrequenz von etwa 25 je 25,4 mm Länge. Bei dieser Verfah- jo rensstufe besitzt der Wirrfaservliesstoff eine gewisse Festigkeit, dank des mechanischen Bindeffekts der gekräuselten Bindefasern in der Bahn, aber beim Handhaben neigt er dazu, die Bindefasern wieder abzugeben. Um die Bindefasern fest in der Bahn zu binden, wird daher der Textilstoff in einem Ofen 2 Minuten unter einer sauerstofffreien Atmosphäre auf 250° C erhitzt, so daß die niedrigschmelzende Komponente der Bindefasern klebrig und in dem Faservlies verankert wird, so daß ein eine gute Reißfestigkeit aufweisender Wirrfaservliesstoff erhalten wird. Dieser enthält etwa 15 Gewichtsprozent Bindefasern, besitzt einen weichen Griff, guten Faltenwurf und eine Reißfestigkeit von ungefähr 0,2 g je Denier.The nonwoven web is immersed in boiling water for 3 minutes to curl the binding fibers and to be entangled in the nonwoven fabric. The crimped binder fibers have a crimp frequency of about 25 each 25.4 mm in length. At this stage of the process, the tangled fiber nonwoven has a certain amount Strength, thanks to the mechanical binding effect of the crimped binding fibers in the web, but at the When handling, it tends to release the binding fibers again. Around the binding fibers firmly in the web To bind, the fabric is therefore placed in an oven for 2 minutes under an oxygen-free atmosphere heated to 250 ° C, so that the low-melting component of the binding fibers sticky and in the Nonwoven fabric is anchored so that a random fiber nonwoven fabric exhibiting good tear resistance is obtained will. This contains about 15 percent by weight of binding fibers, has a soft handle, good folds and a tenacity of about 0.2 grams per denier.

Das Verfahren von Beispiel 1 wurde wiederholt, wobei Wirrfaservliesstoffe mit verschiedenen Prozentgehalten an Bindefasern hergestellt wurden. Der Prozentgehalt an Bindefasern in dem Wirrfaservliesstoff sowie die Reißfestigkeit desselben sind in der Tabelle angegeben.The procedure of Example 1 was repeated, with random fiber nonwovens having different percentages on binding fibers.

Wirrfaservliesstoffe, welche mehr als ungefähr 45% Bindefasern enthalten, besitzen einen rauhen Griff und verhältnismäßig schlechten Faltenwurf.Random fiber nonwovens which contain more than about 45% binding fibers have a rough texture Handle and relatively poor folds.

Die Bindefasern aus Heterofäden können nicht nur durch Eintauchen in siedendes Wasser, sondern auch mit Hilfe anderer Mittel gekräuselt werden, so können sie einer Dampfbehandlung, trockener Hitze oder einer chemischen Behandlung unterworfen werden. Wenn überhitzter Dampf verwendet wird und die potentiell klebende Komponente des Heterofadens einen ausreichend niedrigen Schmelzpunkt aufweist, so können die Kräuselungs- und Verklebungsstufen gleichzeitig ausgeführt werden.The binding fibers made of hetero threads can not only be immersed in boiling water, but Can also be curled with the help of other means, so they can be steamed, dry heat or subjected to chemical treatment. When using superheated steam and the potentially adhesive component of the heterofilament has a sufficiently low melting point the crimping and gluing steps can be carried out simultaneously.

Abwandlungen im Griff und des Oberflächeneffektes eines Wirrfaservliesstoffes können durch Anwendung anderer Verfahren, wie z. B. Nadelstecken des Faservlieses, in das die Bindefasern eingearbeitet sind, vor dem Verbindevorgang erhalten werden.Modifications in the handle and the surface effect of a random fiber nonwoven can be achieved by Use of other methods, such as B. needle sticking of the nonwoven fabric into which the binding fibers are incorporated are obtained before the joining process.
