Description

Vorliegende Erfindung fällt in das Gebiet der nichtgewebten Produkte aus thermoplastischen Polymeren und hat zum Gegenstand ein nichtgewebtes Vlies aus thermogebundenen Fäden oder Fasern.The present invention is in the field of nonwoven products Made of thermoplastic polymers and has the subject of a non-woven Nonwoven made of thermally bound threads or fibers.

Es ist bekannt, daß man, um ein nichtgewebtes Vlies strukturell zu verstärken (Kohäsion, mechanische Eigenschaften), auf die Thermobindung zurückgreift.It is known to structurally to make a nonwoven web reinforce (cohesion, mechanical properties) on the thermal bond falls back.

Zu diesem Zweck umfasst das Vlies im allgemeinen zwei Typen von Fäden oder Fasern aus zwei unterschiedlichen polymeren Materialien oder aus Fäden oder Fasern, die aus zwei verschiedenen polymeren Materialien geformt sind, die trennbar oder nicht trennbar sind, von denen eines dazu bestimmt ist, die bindende Substanz zu bilden, die eine niedrigere Plastifizierungs- und/oder Schmelztemperatur besitzt als das andere Polymer, das dazu bestimmt ist, die Struktur des Vlieses zu bilden.For this purpose, the nonwoven generally comprises two types of Threads or fibers made from two different polymeric materials or from Threads or fibers formed from two different polymeric materials are separable or non-separable, one of which is intended to form the binding substance that has a lower plasticization and / or Melting temperature than the other polymer, which is designed to Form the structure of the fleece.

Die Konfigurationen der gegenwärtig für die Herstellung dieses Typs thermobindfähiges Vlies eingesetzten Fäden oder Fasern sind im wesentlichen drei, nämlich

  • 1) eine zufällige Verteilung von zwei Arten unabhängiger Fäden oder Fasern, von denen der eine die bindende, der andere die strukturelle Komponente darstellt, die getrennt extrudiert oder als zusammengesetzte Monofäden coextrudiert und danach in zwei Arten, den beiden Polymeren entsprechenden Elementarfäden gespalten werden,
  • 2) Fäden oder Fasern, die aus einer bindenden Polymerhülle und einem strukturellen Polymerkern oder -herz bestehen,
  • 3) Zweilamellige Fäden oder Fasern, die einen bindenden und einen strukturellen Streifen aufweisen.
    • The configurations of the filaments or fibers currently used to manufacture this type of thermobondable nonwoven are essentially three, namely
  • 1) a random distribution of two types of independent threads or fibers, one of which is the binding, the other the structural component, which extrudes separately or co-extrudes as composite mono threads and is then split into two types of filaments corresponding to the two polymers,
  • 2) threads or fibers which consist of a binding polymer shell and a structural polymer core or heart,
  • 3) Two-lamellar threads or fibers that have a binding and a structural strip.

    • Jede dieser Konfigurationen weist jedoch Nachteile und/oder Einschränkungen auf. However, each of these configurations has disadvantages and / or Restrictions on.

    So führt die Konfiguration 1) wegen ihrer zufälligen und unregelmäßigen Verteilung der bindenden Fäden oder Fasern zu einer nicht homogenen thermogebundenen Vliesstruktur, was ihre mechanischen Eigenschaften anbetrifft, auf ihrer gesamten Oberfläche.So the configuration 1) performs because of its random and irregular Distribution of the binding threads or fibers to a non-homogeneous thermobonded nonwoven structure, what their mechanical properties applies to their entire surface.

    Die Konfiguration 2) kann leicht zu einem Überschuss an thermobindender Substanz führen, wodurch es zu Bindungen an unerwünschten Stellen kommt, erfordert erhebliche Mengen an bindendem Polymer, kann eine unerwünschte Ausdehnung der Oberfläche der Thermobindungspunkte oder -stellen hervorrufen und bringt einen Mangel an Flexibilität bei der Regulierung der Parameter der Thermobindungen mit sich.The configuration 2) can easily lead to an excess lead to thermobinding substance, causing it to bind unwanted spots, requires significant amounts of binding Polymer, can cause an undesirable expansion of the surface of the Create thermal binding points or locations and introduce a deficiency Flexibility in regulating the parameters of thermal bonds with it.

    Die Konfiguration 3) führt zu Thermobindungen begrenzter Intensität auf Grund der eingeschränkten Oberfläche des Bindungskontakts, des Fehlens ausreichender Thermobindungen an den gewollten Stellen, das von einer inadäquaten unkontrollierbaren Positionierung der Fasern oder Fäden und der allzu inhomogenen Verteilung des bindenden Polymers in den Fasern oder Fäden herrührt.Configuration 3) leads to thermal bonds of limited intensity Because of the limited surface of the bonding contact, the lack of it sufficient thermal bonds at the desired points, that of a inadequate uncontrollable positioning of the fibers or threads and the too inhomogeneous distribution of the binding polymer in the fibers or Threads comes from.

    Diese Erfindung hat insbesondere zum Ziel, den Nachteilen abzuhelfen und die vorgenannten Einschränkungen zu überwinden.The aim of this invention is in particular to remedy the disadvantages and to overcome the aforementioned limitations.

    Zu diesem Zweck hat sie ein nichtgewebtes Vlies zum Gegenstand, das mindestens zum Teil aus Endlosfäden oder zusammengesetzten Fasern hergestellt wird, die aus mindestens zwei Komponenten und aus thermoplastischen polymeren Materialien bestehen, das dadurch gekennzeichnet ist, dass es mindestens teilweise aus einheitlichen Fäden oder Fasern besteht, die zu 5 % bis 50 % ihres Gewichts ein Polymer umfassen, das dazu bestimmt ist, das Bindemittel darzustellen, und in ihrem Querschnitt mindestens zwei unterschiedliche Polymerbereiche oder -zonen aufweisen, die das Bindemittel darstellen, und/oder mindestens zwei unterschiedliche Polymerbereiche oder -zonen aufweisen, die die strukturelle(n) Komponente(n) des resultierenden Vlieses darstellen, wobei dieses Vlies nach der Herstellung einer Behandlung durch Thermobindung unterzogen wird.For this purpose, it has the object of a non-woven fleece, the at least in part from continuous filaments or composite fibers is made up of at least two components and thermoplastic polymer materials consist of this is characterized in that it is at least partially made of uniform threads or Fibers consisting of 5% to 50% by weight of a polymer which is intended to represent the binder, and in its cross section have at least two different polymer regions or zones which represent the binder, and / or at least two different ones Have polymer areas or zones that comprise the structural component (s) represent the resulting fleece, this fleece after production undergoes thermal bonding treatment.

    Das konsolidierte Produkt ergibt ein Vlies für die Watteherstellung von 2,5 cm Dicke, die zur Fütterung von alpiner Kleidung bestimmt ist. Die Eigenschaften der produzierten Oberfläche erlauben auf Grund ihrer Elastizität das Waschen in der Maschine oder eine Reinigung, ohne daß Isolierfähigkeit, Geblähtheit, Geschmeidigkeit und Weichheit verloren gehen. Die Kohäsion des Fasernetzes und die Qualität der Thermobindung verhindern es, daß sich freie Fasern bilden, die die Tendenz hätten, durch die das Fütterungsvlies um hüllende textilen Oberflächen hindurchzuwandern.The consolidated product results in a fleece for the production of cotton wool 2.5 cm thick, which is intended for feeding alpine clothing. The Properties of the surface produced allow due to their elasticity machine washing or cleaning without insulation, Bloating, suppleness and softness are lost. The cohesion of Fiber network and the quality of the thermal bond prevent it from free Form fibers that would have the tendency through which the feeding fleece to wander through enveloping textile surfaces.
