Definitions

B. Super absorber.
  • the possibility of producing the two inner layers from different fibers, which have different tasks, properties, has the advantage that such a wipe, hygiene product or the like can solve different tasks on the two surfaces.
  • One side can e.g. B. more liquid absorb than the other, but you can better rub or act with this other surface.
  • One inner layer can consist of longer pulp fibers up to 30 mm in length, while the other layer can be made of shorter pulp fibers such as 2-5 mm or of hydrophilic synthetic fibers. Flax fibers, SAP fibers or those with a different cross-sectional profile can also be used.
  • the two inner layers can both have absorbent properties, but additionally differ significantly.
  • the two outer layers should consist of carded fiber layers, spunbond, meltblown nonwovens or fibers of another fiber structure, the fiber lengths of which can be adapted to the respective product.

  • individual, pre-formed tissue layers can also be deposited for sandwich fleece formation. It is also conceivable to form a sandwich fleece, in which the individual layers are pulled off a roll with wound single fleeces, grids, fabrics and the like. If a card is used that produces two or three layers of carding fibers (i.e. over two or three customers), only the upper layer can be subjected to calendering, hot air bonding or another type of pre-bonding, which gives the handle of the finished product-determining lower layer remains fluffy.

Abstract

Das neue Produkt besteht aus hydrodynamisch verfestigten Vliesschichten, von denen mindestens vier Schichten übereinander gelegt werden und dann nur mit harten Wasserstrahlen miteinander verbunden werden.

Description

Produkt und Verfahren zur Herstellung eines Vliesstoffes mittels hydrodynamischer Ver- nadelung
Durch die US-A-6 1 10 848 ist ein dreilagiges Sandwichvlies bekannt, dessen Außenschichten aus Stapelfasern einer Länge von 30 - 100 mm Länge bestehen und das in der Mitte ein Pulpvlies aufweist, das auch aus einem Gemisch aus und mit anderen Fasern wie Naturfasern oder Synthesefasern bestehen kann.
Der Erfindung liegt die Aufgabe zugrunde, ein Sandwichvlies zu bilden, das besondere Eigenschaften ermöglicht. So soll das Endprodukt z. B. einseitig stark flüssigkeitsaufnahmefähig sein, während die andere Oberfläche eher dicht oder für andere Flüssigkeiten zur Aufnahme besser geeignet sein soll, jedenfalls sich von der anderen Oberfläche in seinen Eigenschaften unterscheiden soll.
Zur Lösung der Aufgabe ist vorgesehen, den Vliesstoff aus mindestens vier Schichten herzustellen, die zur Verfestigung des Vliesstoffes mittels der hydrodynamischen Vernadelung miteinander verbunden sind, wobei die beiden äußeren Schichten aus Vliesen aus kardierbaren Stapelfasern bis 1 00 mm Länge bzw. Spunbond-, Meltblownfasern oder anderen speziellen Fasern bestehen und die mindestens beiden von den Außenschichten abgedeckten Innenschichten aus unterschiedlichen Pulpfasern oder Pulpfasern mit anderen Fasern, wie Synthesefasern oder Naturfasern , bestehen bzw. anderen Fasern oder saugfähigen Substanzen, wie z. B. Superabsorber.
Die Möglichkeit, die beiden inneren Schichten aus unterschiedlichen Fasern, die unterschiedliche Aufgaben, Eigenschaften haben, herzustellen, hat den Vorteil, dass ein solches Wischtuch , Hygieneprodukt oder dgl. auf den beiden Oberflächen unterschiedliche Aufgaben lösen kann. Die eine Seite kann z. B. mehr Flüssigkeit aufnehmen als die andere, dafür kann man aber mit dieser anderen Oberfläche besser reiben od. dgl. agieren . So kann die eine Innenschicht aus längern Pulpfasern bis zu 30 mm Länge bestehen, während die andere Schicht aus kürzeren Pulpfasern wie 2 - 5 mm oder aus hydrophilen Synthesefasern hergestellt sein kann. Auch können Flachsfasern, SAP-Fasern oder solche mit einem anderen Querschnittsprofil zur Anwendung kommen. Die beiden Innenschichten können beide saugende Eigenschaften haben, jedoch zusätzlich sich wesentlich unterscheiden.
Die beiden Außenschichten sollten aus kardierten Faserschichten , aus Spunbond-, Meltblownvliesen oder aus Fasern anderer Faserstruktur bestehen, deren Faserlängen dem jeweiligen Produkt angepasst werden kann. Es kann aber auch ein anderes Vliesbildungsverfahren wie Spunbond , Meltblown oder das Nanovalverfahren gemäß der DE-PS 1 99 29 709 zur Anwendung kommen. Selbstverständlich können auch einzelne fertig voraus gebildete Tissueschichten zur Sandwichvliesbildung abgelegt werden. Es ist auch eine Sandwichvliesbildung denkbar, bei der die einzelnen Schichten von einer Rolle mit aufgewickelten Einzelvliesen , Gittern , Geweben und dgl. abgezogen werden. Sollte eine Krempel zum Einsatz kommen, die gleich zwei oder drei Krempelfaserschichten herstellt (d. h. über zwei oder drei Abnehmer) , so können von diesen nur die obere Schicht einer Kalandrierung , einer Heißluftverfestigung oder einer anderen Art der Vorverfestigung unterworfen werden, womit die den Griff des fertigen Produkts bestimmende untere Schicht flauschig verbleibt.
