Description
Faservlies für Absorptionskörper für sanitäre Zwecke Die Erfindung bezieht sich auf ein Faservlies für Absorptionskörper für sanitäre Zwecke, insbesondere für Damenbinden, die in feuchtem Zustand nicht zusammenfallen, sondern ihre Elastizität und ihr ursprüngliches Volumen (trockener Zustand) weitgehend beibehalten sollen.Nonwoven fabric for absorbent bodies for sanitary purposes The invention relates to a nonwoven fabric for absorbent bodies for sanitary purposes, in particular for sanitary napkins that do not collapse when wet, but their elasticity and should largely retain their original volume (dry state).
Man hat bereits vorgeschlagen, Tampons mit einer Füllung aus einem Gemisch von hydrophilen und hydrophoben Fasern herzustellen. Der Tampon soll sich auf engstem Raum zusammenpressen lassen und sich dann unter der Einwirkung von Feuchtigkeit (Sekreten, Blut u. dgl.) beträchtlich ausdehnen, um bestimmungsgemäß den Ort seines Einsatzes auszufüllen. Den Absorptionskörpern der Erfindung liegt demgegenüber die Aufgabe zugrunde, im feuchten Zustand nicht zusammenzufallen und sich im Volumen nicht zu verkleinern bzw. um ein Vielfaches aufzuquellen, sondern bei Gebrauch neben ausreichender Elastizität ihr ursprüngliches Volumen beizubehalten. It has already been proposed to use tampons with a filling of one To produce a mixture of hydrophilic and hydrophobic fibers. The tampon should be Can be pressed together in a confined space and then under the action of moisture (Secretions, blood and the like.) Extend considerably to the intended location of his To fill in the stake. The absorbent bodies of the invention, on the other hand, is the The task is not to collapse when wet and not to collapse in volume not to be reduced in size or to swell up many times over, but when used alongside sufficient elasticity to maintain their original volume.
Die Erfindung besteht darin, daß den hydrophilen und/oder hydrophoben Fasern des Vlieses hydrophile und/oder hydrophobe schaumstoffartige Teilchen feinverteilt zugegeben und mit den Fasern verbunden sind und die Mischung hydrophobe und hydrophile Bestandteile enthält. Dabei hat sich nun gezeigt, daß ein solches Faservlies zur Erhöhung der Flüssigkeitsaufnahme, also des Adsorptionsvermögens und zur Verbesserung der Weichheit des Fasergebildes beiträgt. The invention consists in that the hydrophilic and / or hydrophobic Fibers of the fleece hydrophilic and / or hydrophobic foam-like particles finely divided are added and connected to the fibers and the mixture is hydrophobic and hydrophilic Contains ingredients. It has now been shown that such a fiber fleece for Increase in liquid absorption, i.e. the adsorption capacity and for improvement contributes to the softness of the fiber structure.
Die schaumstoffartigen Teilchen können beispielsweise an sich bekannte Polyurethanschaumstoffe auf Isocyanatbasis sein. Die Schaumstoffe werden in feinverteilter Form, z. B. als Schnitzel, angewandt, wie sie bei anderweitigen Fertigungen als Abfall anfallen. Die in genannter Weise hergestellten Schaumstoffe sind hydrophob. Sie können als langgezogene Fäden oder als Schnüre vorliegen. Werden solche in Faden- oder Schnitzelform vorliegenden Schaumstoffe mit hydrophilen Fasern, z. B. Cellulosefasern, auf das innigste miteinander gemischt, so wird das unliebsame Zusammenfallen der Bestandteile im feuchten Zustand vermieden, das Gemisch besitzt dagegen stets die gewünschte Rückprallelastizität. The foam-like particles can, for example, be known per se Isocyanate-based polyurethane foams. The foams are finely divided into Shape, e.g. B. as Schnitzel, used as in other manufacturing than Waste incurred. The foams produced in this manner are hydrophobic. They can be in the form of elongated threads or cords. Are those in thread or in chip form foams with hydrophilic fibers, e.g. B. cellulose fibers, mixed with one another in the most intimate way, the unpleasant coincidence of the Components avoided in the wet state, the mixture, however, always has the desired rebound resilience.
Als geeignete Schaumstoffteilchen können die aus den verschiedensten elastischen Hochpolymeren in Frage kommen. Besonders vorteilhaft sind die aus Polyglykolen und Diisocyanaten unter Gasabspaltung gewonnenen Polyurethanschaumstoffe. Suitable foam particles can be any of the most varied elastic high polymers come into question. Those made from polyglycols are particularly advantageous Polyurethane foams obtained with elimination of gas and diisocyanates.
Schaumstoffe für diesen Einsatzzweck können aber auch aus jedem anderen verschäumbaren Material nach bekannten Verfahren erzeugt werden. So kön- nen in Latex oder hochpolymere Kunststoffe, vorzugsweise bei hohen Temperaturen, bei denen sie weichflüssig sind, Neutralgase, Kohlendioxyd, Luft od. dgl. eingeleitet oder Treibmittel oder Stoffe, die von sich aus Gase entwickeln, zugesetzt werden. Bei Auswahl geeigneter Massen können somit nicht nur hydrophobe, sondern auch hydrophile Schaumstoffe erzeugt und beigemischt werden. Diese Schaumstoffe werden in der erfindungsgemäßen Weise fein zerteilt bzw. zu Fäden oder Schnüren verarbeitet verwendet. d. h. je nach ihren hydrophoben oder hydrophilen Eigenschaften in angemessener Form mit den sich hinsichtlich der Feuchtigkeitsaufnahme umgekehrt verhaltenden Fasern innig vermischt und durch Anwendung von Wärme, Druck, chemischen oder physikalischen Mitteln verbunden. Die Mischung kann auch aus mehreren Bestandteilen, z. B. teils hydrophoben, teils hydrophilen Fasern und den entsprechenden Schaumstoffen bestehen. Durch diesen je nach den Bedürfnissen angepaßten Austausch der Komponenten lassen sich besonders tragegünstige Erzeugnisse herstellen. Foams for this purpose can also be made from any other foamable material can be produced by known methods. So can- in latex or high polymer plastics, preferably at high temperatures at which they are soft, neutral gases, carbon dioxide, air or the like. Introduced or propellants or substances that develop gases by themselves are added. When choosing a suitable one Masses can thus not only produce hydrophobic, but also hydrophilic foams and mixed in. These foams are made in the manner according to the invention used finely divided or processed into threads or cords. d. H. depending on theirs hydrophobic or hydrophilic properties in an appropriate form with the regarding The fibers that behave in reverse to the moisture absorption are intimately mixed and through Application of heat, pressure, chemical or physical means. the Mixture can also consist of several ingredients, e.g. B. partly hydrophobic, partly hydrophilic Fibers and the corresponding foams exist. Through this depending on the needs Adapted replacement of the components can be used to create products that are particularly inexpensive to wear produce.
Die Vliese enthalten je nach Bedarf zusätzlich noch Farb- und Füllstoffe, Desinfizientien und Wirkstoffe, wie z. B. desodorisierende Mittel. The fleeces also contain dyes and fillers as required, Disinfectants and active ingredients, such as B. deodorants.
