Furthermore, the use becomes permanently hydrophilic polyolefin inconveniencer materials and the corresponding method for the preparation of Wipes described.
- Wipes that are used in the personal hygiene sector such as facial tissues, cosmetic pads, baby wipes, personal hygiene and household and industrial wipes are mostly used in aqueous medium and require good wettability with polar liquids.
- hydrophilic fibers such as cellulose fibers, such as viscose or pulp, or their combination with polyester or polypropylene, are mostly used for the production of wipes.
- the web formation takes place via an airlaid or carding process with subsequent chemical, thermal or mechanical bonding.
- These so-called staple fiber webs often have insufficient abrasion resistance. Acceptable abrasion resistance must be paid for with pure staple fiber webs with a reduced sensor technology. It is therefore desirable to produce nonwovens which were either produced exclusively from a spunbonded nonwoven or which have a composite structure in which at least one layer consists of a spunbonded nonwoven.
- Spunbonded nonwovens are generally made of thermoplastics (polyesters, polyolefins) produced. These can be obtained without the addition of hydrophilic additives due to the insufficient water absorption of the pure polymers are not used for wipes, where absorption of hydrophilic substances or aqueous emulsions is desired ..

Abstract
Description
Die Erfindung befindet sich auf dem Gebiet der Textiltechnik und betrifft polyolefinhaltige Wischtücher, die durch Hydrophilieadditive permanent hydrophiliert und nachfolgend einer Imprägnierung mit Spinnpräparationen und/oder wässrigen Lösungen und/oder Emulsionen unterzogen sind. Desweiteren wird die Verwendung permanent hydrophilierter polyolefinhaltiger Materialien sowie das entsprechende Verfahren zur Herstellung von Wischtüchern beschrieben.The invention is in the field of textile technology and relates to polyolefinhaltige Wipes permanently hydrophilized by hydrophilic additives and subsequently an impregnation with spin finishes and / or aqueous solutions and / or emulsions are subjected. Furthermore, the use becomes permanently hydrophilic polyolefinhaltiger materials and the corresponding method for the preparation of Wipes described.
Wischtücher, die im persönlichen Hygienebereich eingesetzt werden wie Gesichtstücher,
Kosmetikpads, Babytücher, Körperhygiene sowie Wischtücher für den Haushalt und für
den industriellen Bereich werden meistens im wässrigen Medium eingesetzt und benötigen
eine gute Benetzbarkeit mit polaren Flüssigkeiten.
Bislang werden daher meistens hydrophile Fasern wie Cellulosefasern, wie Viskose oder
Pulp, oder deren Kombination mit Polyester oder Polypropylen für die Herstellung von
Wischtüchern verwendet. Die Vliesbildung erfolgt über einen Airlaid - oder Kardierprozess
mit anschließender chemischer, thermischer oder mechanischer Bondierung.
Diese sogenannten Stapelfaservliese weisen häufig eine unzureichende Abrasionsbeständigkeit
auf. Akzeptable Abrasionsbeständigkeiten müssen bei reinen Stapelfaservliesen
mit einer reduzierten Sensorik erkauft werden.
Es ist daher wünschenswert Vliese herzustellen, die entweder ausschließlich aus einem
Spinnvlies hergestellt wurden oder die eine Kompositstruktur aufweisen, bei der zumindest
eine Schicht aus einem Spinnvlies besteht.Wipes that are used in the personal hygiene sector such as facial tissues, cosmetic pads, baby wipes, personal hygiene and household and industrial wipes are mostly used in aqueous medium and require good wettability with polar liquids.
So far, hydrophilic fibers, such as cellulose fibers, such as viscose or pulp, or their combination with polyester or polypropylene, are mostly used for the production of wipes. The web formation takes place via an airlaid or carding process with subsequent chemical, thermal or mechanical bonding.
These so-called staple fiber webs often have insufficient abrasion resistance. Acceptable abrasion resistance must be paid for with pure staple fiber webs with a reduced sensor technology.
It is therefore desirable to produce nonwovens which were either produced exclusively from a spunbonded nonwoven or which have a composite structure in which at least one layer consists of a spunbonded nonwoven.
Spinnvliese werden im Allgemeinen aus thermoplastischen Kunststoffen (Polyester, Polyolefine) hergestellt. Diese können ohne Zusatz von hydrophilen Additiven aufgrund der zu geringen Wasserabsorption der reinen Polymere nicht für Wischtücher verwendet werden, bei denen eine Absorption von hydrophilen Substanzen oder wässrigen Emulsionen erwünscht wird..Spunbonded nonwovens are generally made of thermoplastics (polyesters, polyolefins) produced. These can be obtained without the addition of hydrophilic additives due to the insufficient water absorption of the pure polymers are not used for wipes, where absorption of hydrophilic substances or aqueous emulsions is desired ..
Es ist prinzipiell möglich, die Fasern durch nachträgliches Beschichten mit entsprechenden Produkten die nötigen hydrophilen Eigenschaften zu verleihen (Spinnpraeparationen oder Avivagen) oder bereits durch Zusatz geeigneter Additive bei der Herstellung der Fasern, diese ausreichend hydrophil auszurüsten (interne Additive). Letzteres wird in der EP 723 607 B1 beschrieben, wobei dort Diester von Polethylenglykol mit Fettsäuren bzw. deren Derivaten als geeignete permanenten Additive offenbart werden. Aus der Europäischen Anmeldung EP 1 138 810 A1 sind weiterhin spezielle Umsetzungsprodukte von zwei Teilen einer C 10 bis C 12-Fettsäure mit Polyethylenglykolen bekannt, die sich als interne Additive zur Hydrophilierung von Polyolefinfasern eignen. Ebenso beschreibt die Internationale Anmeldung WO 02/092891 Hydrophilieadditive zur permanenten internen Hydrophilierung von Polyolefinen.It is in principle possible to give the fibers by subsequent coating with appropriate products the necessary hydrophilic properties (spin finishes or finishing agents) or already by adding suitable additives in the production of the fibers to provide them sufficiently hydrophilic (internal additives). The latter is described in EP 723 607 B1 , where diesters of polyethylene glycol with fatty acids or their derivatives are disclosed as suitable permanent additives. European application EP 1 138 810 A1 furthermore discloses special reaction products of two parts of a C 10 to C 12 fatty acid with polyethylene glycols which are suitable as internal additives for the hydrophilization of polyolefin fibers. Likewise, International Application WO 02/092891 describes hydrophilic additives for permanent internal hydrophilization of polyolefins.
Derartige Additive werden in der Regel zusammen mit einem Polyolefin-Granulat zu einem Vorgemisch (Masterbatch) verarbeitet, das dann als solches dem Polymergranulat vor der Verarbeitung zur Faser oder zu sonstigen Endprodukten zugesetzt und anschließend extrudiert wird. Die in der WO 02/092891 beschriebenen Additive können auch direkt während des Extrusionsprozesses in der Extrusionsanlage zudosiert werden.Such additives are usually together with a polyolefin granules to a Pre-mixture (masterbatch) processed, which then as such the polymer granules added before processing to the fiber or other end products and then is extruded. The additives described in WO 02/092891 can also be used directly be dosed during the extrusion process in the extrusion plant.
Die Imprägnierung von Tissuepapieren und Wischtüchern mit Tensiden oder pflegenden
Stoffen, sei es im Haushalts-, Körperpflege- oder kosmetischen Bereich, hat sich bereits
auf dem Markt seit Jahren durchgesetzt. Ausgehend von der bei den ersten marktreifen
Wischtüchern angestrebten Reinigungsfunktion steht heute immer mehr die Pflege im
Mittelpunkt. So werden beispielsweise in der internationalen Patentanmeldung WO
95/35411 Feuchttücher vorgeschlagen, welche mit einer Lotion imprägniert sind, die neben
Mineralöl, Fettsäureester, Fettalkoholethoxylate und Fettalkohole enthalten.
Seit einiger Zeit werden auch Tücher angeboten, die in trockener Form vorliegen und vor
der Anwendung befeuchtet werden müssen, so stellvertretend beschrieben in den Patentanmeldungen
WO 99/13861 und WO 01/08657. Die Herstellung solcher Tücher ist je
nach eingesetzten Materialien relativ teuer, insbesondere da viele Stoffe nicht recyclingfähig
sind.
Trotz bekannter Marktreife sollen die Anwendungseigenschaften üblicher Wischtücher
dennoch verbessert werden. The impregnation of tissue papers and wipes with surfactants or caring substances, whether in the household, personal care or cosmetic sector, has already been on the market for years. Based on the cleaning function aimed for with the first market-ready wipes, care is now increasingly the focus of attention. Thus, for example, International Patent Application WO 95/35411 proposes wet wipes which are impregnated with a lotion which contains, in addition to mineral oil, fatty acid esters, fatty alcohol ethoxylates and fatty alcohols.
For some time, wipes are also available which are in dry form and must be moistened before use, as described by way of example in the patent applications WO 99/13861 and WO 01/08657 . The production of such cloths is relatively expensive depending on the materials used, especially since many substances are not recyclable.
Despite known market maturity, the application properties of conventional wipes should still be improved.
Aufgabe der vorliegenden Erfindung ist es vielseitig einsetzbare Wischtücher zur Verfügung zu stellen, die trotz preisgünstiger Herstellung vorteilhafte Anwendungs-, Reinigungs- und Pflegeeigenschaften aufweisen. Object of the present invention is versatile wipes available despite advantageous production, advantageous application, cleaning and and care properties.
Gegenstand der vorliegenden Erfindung sind Wischtücher, erhältlich durch permanente Hydrophilierung Polyolefine enthaltender Materialien mit einem Hydrophilieadditiv und nachfolgende Imprägnierung der aus diesen Materialien hergestellten Vliese mit Spinnpräparationen und/oder wässrigen Lösungen und/oder Emulsionen.The present invention relates to wipes obtainable by permanent Hydrophilization of polyolefin-containing materials with a hydrophilic additive and subsequent impregnation of the nonwovens made from these materials with spin finishes and / or aqueous solutions and / or emulsions.
Überraschender Weise wurde festgestellt, dass die erfindungsgemäßen Wischtücher einerseits eine bessere Abgabe der Lösungen und Emulsionen, mit denen sie imprägniert sind, aufweisen, was sich durch ein angenehmeres Hautgefühl nach der Anwendung bemerkbar macht. Durch die Kombination einer Imprägnierung mit einer Emulsion (O/W oder W/O) können 2-Phasen-Reinigungstücher produziert werden, die zunächst ein kühlendes/reinigendes Gefühl auf der Haut erzeugen um zuletzt einen cremenden Effekt auf der Haut zu hinterlassen. Dieser Effekt ist nicht nur bei Spinnvliesen, sondern auch bei kardierten Vliesen, die hydrophilierte Polypropylen-Stapelfasern enthalten, zu beobachten.Surprisingly, it was found that the wipes of the invention on the one hand a better release of the solutions and emulsions with which they are impregnated, which is noticeable by a more pleasant skin feel after the application power. By combining an impregnation with an emulsion (O / W or W / O) 2-phase cleaning wipes can be produced, which are initially a cooling / cleansing Feeling on the skin produce a creamy effect on the last Leave skin behind. This effect is not only with spunbonded nonwovens but also with carded ones Nonwovens containing hydrophilized polypropylene staple fibers can be observed.
Andererseits bemerkt man auch bei längerer Lagerung gestapelter Tücher kein "Settlen" resp. Ausbluten der Imprägnierlösungen. Stapel aus herkömmlichen Tüchern zeigen bereits nach wenigen Tagen Lagerung ein Absinken der äußeren Phase der Emulsion oder bei Lösungen der gesamten Lösung innerhalb der Stapels bedingt durch die Einwirkung der Schwerkraft und Kapillarkräfte.Bei Stapeln aus den erfindungsgemäßen Tüchern wird diese ungleiche Verteilung der Imprägniermittel vermieden, so dass die Gefahr des Austrocknens der oben gelagerten Tücher nicht gegeben ist. Nebenbei weisen die erfindungsgemäßen Vliese eine ausgezeichnete Abrasionsbeständigkeit auf.On the other hand, you notice even with prolonged storage of stacked towels no "settling" respectively. Bleeding out of the impregnation solutions. Stacks of traditional towels already show after a few days storage, a decrease in the outer phase of the emulsion or in solutions of the entire solution within the stack due to the action gravity and capillary forces. When stacked from the wipes of the invention This uneven distribution of impregnants avoided, so the risk of dehydration the above stored towels is not given. By the way, the inventive Nonwovens have excellent abrasion resistance.
Desweiteren zeichnen sich die erfindungsgemäßen Tücher durch eine preiswertere Herstellung,
höhere Herstellungsgeschwindigkeit und durch ihr geringeres Gewicht bei ausgesprochen
hohem Weichheitsgrad aus. Die Weichheit wird durch den Zusatz der
hydrophilen Additive in Polypropylen erreicht. Die abrasionsbeständigen Vliese verbessern
zusätzlich den Reinigungseffekt, da einen höherer Druck bei der Anwendung möglich
ist in Vergleich zu reinen Stapelfaservliesen. Ferner können die reinen hydrophilierten
Polyolefinvliese mit Recyclingverfahren einer Wiederverwendung zugeführt werden,
wie sie bei Kombination mit Cellulosefasern nicht möglich sind.
Für das Konvertieren der Wischtücher ist es wichtig, dass sich die Tücher leicht falten
lassen und sich nicht während des Konvertierens von selbst auseinander falten. Das geringe
Vliesgewicht und die Weichheit der mit hydrophilen Additiven hergestellten Vliese
wirkt sich günstig auf diesen "Memory-Effekt" aus in Vergleich zu reinen PES/Viskose-Mischungen.Furthermore, the wipes of the invention are characterized by a cheaper production, higher production speed and by their lower weight at a very high degree of softness. The softness is achieved by the addition of hydrophilic additives in polypropylene. The abrasion-resistant nonwovens additionally improve the cleaning effect, since a higher pressure during use is possible in comparison to pure staple fiber webs. Furthermore, the pure hydrophilized polyolefin nonwovens can be recycled by recycling, as they are not possible when combined with cellulose fibers.
When converting wipes, it is important for the wipes to fold easily and not to unfold automatically during converting. The low nonwoven weight and the softness of the nonwovens produced with hydrophilic additives has a favorable effect on this "memory effect" in comparison to pure PES / viscose mixtures.
Die Wischtücher können im persönlichen Hygienebereich eingesetzt werden, wie Gesichtstücher, Kosmetikpads, Babytücher, Körperhygienetücher, aber auch als Reinigungstücher für den Haushalt und für den industriellen Bereich. Dabei kann es sich um trockene Wischtücher oder um sogenannten Feuchtücher handeln. Hydrophile Polyolefinvliese absorbieren hydrophile Lösemittel wie Wasser, Alkohole , Glykole, in nahezu gleichem Masse wie hydrophobe Substanzen, wie Mineralöle Esteröle und Silikoneole. Diese Eigenschaft ist besonders für Industriewischtücher von Bedeutung, da hier eine gute Absorption von hydrophilen als auch hydrophoben Substanzen gewünscht ist.The wipes can be used in personal hygiene areas, such as facial tissues, Cosmetic pads, baby wipes, body hygiene wipes, but also as cleaning wipes for the household and for the industrial sector. It can be dry Wipes or so-called wet wipes. Hydrophilic polyolefin nonwovens absorb hydrophilic solvents such as water, alcohols, glycols, in almost the same way Mass such as hydrophobic substances, such as mineral oils ester oils and silicone brine. This attribute is particularly important for industrial towels, as here is a good Absorption of hydrophilic and hydrophobic substances is desired.
Die Verwendung von permanent hydrophilierten Polyolefinmaterialien zur Herstellung von imprägnierten Wischtüchern ist daher ein weiterer Gegenstand der Erfindung.The use of permanently hydrophilized polyolefin materials for the manufacture of impregnated wipes is therefore a further object of the invention.
Ebenfalls ist das Verfahren zur Herstellung von Wischtüchern, bei dem man polyolefinhaltige Materialien mit einem Hydrophilieadditiv permanent hydrophiliert und die daraus hergestellten Vliese einer Imprägnierung mit Spinnpräparationen und/oder wässrigen Lösungen und/oder Emulsionen unterzieht, Gegenstand der vorliegenden Erfindung.Also, the process for producing wipes, wherein polyolefinhaltige Materials with a Hydrophilieadditiv permanently hydrophilized and the resulting Nonwovens produced impregnation with spin finishes and / or aqueous solutions and / or emulsions, subject of the present invention.
Die polyolefinhaltigen Materialien werden dabei nach den üblichen Methoden des Standes der Technik intern permanent hydrophiliert und die daraus hergestellten Tücher werden nachfolgend imprägniert. Das Imprägnierung erfolgt durch Sprühen, Tauchen, Bedrucken oder Walzenapplikation, wobei eine mehrfache Imprägnierung mit gleichen oder unterschiedlichen Formulierungen möglich ist.The polyolefin-containing materials are doing by the usual methods of the state The technology internally permanently hydrophilized and the towels made from it subsequently impregnated. The impregnation is done by spraying, dipping, printing or roller application, wherein a multiple impregnation with the same or different formulations is possible.
Beim ersten Imprägnieren haben sich die üblicherweise eingesetzten Lösungen/Emulsionen von Spinnpräparationen bewährt. Typische Mittel zur Erstimprägnierung sind Spinnpräparationen, bestehend aus Tensiden und Ölen, die in wässriger Lösung/Emulsion eine Oberflächenspannung von unter 45 dyn/cm bei 20 Grad bei Anwendungskonzentration aufweisen, wie beispielsweise Stantex® S 6327 (Cognis Düsseldorf), Stantex® S 6051-1 (Cognis Düsseldorf). Diese Erstimprägnierung führt zu einer Vergleichmässigung der Hydrophilie und Absorption auf dem Vlies und wirkt sich vorteilhaft auf die Verteilung der Zweitimprägnierung aus. During the first impregnation, the solutions / emulsions usually used have proven by spin finishes. Typical means of initial impregnation are spin finishes consisting of surfactants and oils in aqueous solution / emulsion a surface tension of less than 45 dynes / cm at 20 degrees at application concentration such as Stantex® S 6327 (Cognis Dusseldorf), Stantex® S 6051-1 (Cognis Dusseldorf). This Erstimprägnierung leads to a uniformity the hydrophilicity and absorption on the web and has an advantageous effect on the distribution of the secondary impregnation.
Die Mittel zur Zweitimprägnierung sind Lösungen/Emulsionen bestehend aus Tensiden,
wenn es vorwiegend um Tücher zu Haushalts- und Industriereinigungszwecken geht oder
Tensiden und/oder hautpflegenden Substanzen für den Bereich der Körperhygiene.
So haben sich bei den Emulsionen besonders wässrige Systeme mit pflegenden Komponenten,
wie beispielsweise Belsoft Care® 6600 (Cognis Düsseldorf), oder auch sogenannte
PIT-(Phaseninvasionstemperatur-) Emulsionen bewährt, wie Emulgade® CM
(Cognis Düsseldorf).The second impregnation agents are solutions / emulsions consisting of surfactants, when it comes mainly to towels for household and industrial cleaning purposes or surfactants and / or skin care substances for the field of personal hygiene.
For example, the emulsions have been found to be particularly water-based systems with care components such as Belsoft Care® 6600 (Cognis Dusseldorf), or else so-called PIT (phase invasion temperature) emulsions, such as Emulgade® CM (Cognis Dusseldorf).
Sämtliche Vliesherstellungsverfahren (airlaid, kardierung, wet laid, meltspun inkl meltblown oder spunbond) sowie Bondierungsverfahren (chemisch, thermisch, mechanisch inklusive Wasserstrahlverfestigung) sind möglich. Verschiedene Vlies- und Bondierungsverfahren können kombiniert werden um Kompositvliese herzustellen. Dabei kann auch die erste Imprägnierung auf den einzelnen Vliesen vor der Bondierung erfolgen und anschließend eine zweite Imprägnierung erfolgen.All fleece production processes (airlaid, carding, wet laid, meltspun incl meltblown or spunbond) as well as bonding methods (chemical, thermal, mechanical including hydroentanglement) are possible. Various nonwoven and bonding methods can be combined to produce composite nonwovens. It can also the first impregnation on the individual webs takes place before the bonding and then carried out a second impregnation.

In addition, other known from the prior art additives be added for polymer extrusion or production.
Bezüglich des Polyolefine enthaltenden Materials eigenen sich an sich alle heute bekannten Polymer- und Copolymertypen auf Ethylen- beziehungsweise Propylen-Basis. Auch Abmischungen reiner Polyolefine mit Copolymeren sind grundsätzlich geeignet. Desgleichen können die Hydrophilieadditive in Mischungen aus Polyolefinen mit anderen synthetischen oder natürlichen Polymeren, z.B. Cellulose, Polymilchsäure oder Hanf eingesetzt werden, um den Polyolefinfasern permanent hydrophile Eigenschaften zu geben. Bevorzugt soll das Gewebe mindestens 50 Gew.% Polyolefine enthalten. Die besten Ergebnisse erzielt man jedoch bei reinen Polyolefinhaltigen Vliesen, das heißt das Gewebe besteht aus Polyolefinen mit den üblichen herstellungsbedingten Verunreinigungen.With regard to the material containing polyolefins, all known today are suitable Polymer and copolymer types based on ethylene or propylene. Also Blends of pure polyolefins with copolymers are suitable in principle.

Prefers the fabric should contain at least 50% by weight of polyolefins. The best results However, you get at pure polyolefin-containing nonwovens, that is, the tissue is from polyolefins with the usual manufacturing impurities.
Für die erfindungsgemäße Lehre besonders geeignete Polymertypen sind in der nachfolgenden Zusammenstellung aufgezählt: Poly(ethylene) wie HDPE (high density polyethylene), LDPE (low density polyethylene), VLDPE (very low density polyethylene), LLDPE (linear low density polyethylene), MDPE (medium density polyethylene), UHMPE (ultra high molecular polyethylene), VPE (vernetztes Polyethylen), HPPE (high pressure polyethylene); Poly(propylene) wie isotaktisches Polypropylen; syndiotaktisches Polypropylen; Metallocen-katalysiert hergestelltes Polypropylen, schlagzäh-modifiziertes Polypropylen, Random-Copolymere auf Basis Ethylen und Propylen, Blockcopolymere auf Basis Ethylen und Propylen; EPM (Poly[ethylen-co-propylen]); EPDM (Poly[ethylen-co-propylen-co-konjugiertes Dien]).For the teachings of the invention particularly suitable polymer types are in the following Summary: poly (ethylene) such as HDPE (high density polyethylene), Low density polyethylene (LDPE), very low density polyethylene (VLDPE), LLDPE (linear low density polyethylene), MDPE (medium density polyethylene), UHMPE (ultra high molecular weight polyethylene), VPE (cross-linked polyethylene), HPPE (high pressure polyethylene); Poly (propylene) such as isotactic polypropylene; syndiotactic polypropylene; Metallocene catalysed polypropylene, impact modified polypropylene, Random copolymers based on ethylene and propylene, block copolymers based on ethylene and propylene; EPM (poly [ethylene-co-propylene]); EPDM (poly [ethylene-co-propylene-co-conjugated Diene]).
Im Rahmen der vorliegenden Erfindung sind Homo- und Copolymere auf Basis von Ethylen und Propylen besonders bevorzugt. In einer Ausführungsform der vorliegenden Erfindung setzt man dementsprechend als Polyolefin ausschließlich Polyethylen ein, in einer anderen Ausführungsform ausschließlich Polypropylen, in einer weiteren Ausführungsform Copolymere auf Basis von Ethylen und Propylen.In the context of the present invention are homopolymers and copolymers based on ethylene and propylene is particularly preferred. In an embodiment of the present invention Accordingly, if one uses only polyolefin as polyethylene, in one another embodiment exclusively polypropylene, in a further embodiment Copolymers based on ethylene and propylene.
In einer ganz besonders bevorzugten Ausführungsform der Erfindung werden die Additive in Polypropylenfasern verwendet. Derartige Fasern weisen vorzugsweise eine melt flow rate von größer 10 bis 1500 dg/min (gemessen bei 230 °C und 2,16 kg Belastung) auf wobei Fasern mit beispielsweise 150 bis 1200 oder 20 bis 25 bzw. 400 bis 1000 dg/min bevorzugt sein können.In a most preferred embodiment of the invention, the additives used in polypropylene fibers. Such fibers preferably have a melt flow rate of greater than 10 to 1500 dg / min (measured at 230 ° C and 2.16 kg load) wherein fibers having, for example, 150 to 1200 or 20 to 25 or 400 to 1000 dg / min may be preferred.
Die Gegenstände, vorzugsweise Fasern bzw. Folien, oder Flächengebilden wie Vliesstoffe, aus diesen Fasern, enthalten die Additive vorzugsweise in Mengen von 0,1 bis 5 Gew.-%, vorzugsweise 0,5 bis 5 Gew.-% und insbesondere 1,0 bis 3 Gew.-% bezogen auf das Gesamtgewicht der Gegenstände.The articles, preferably fibers or films, or fabrics such as nonwovens, from these fibers, the additives preferably contain in amounts of 0.1 to 5 wt .-%, preferably 0.5 to 5 wt .-% and in particular 1.0 to 3 wt .-% based on the Total weight of the items.
Vliesstoffe können nach allen im Stand der Technik bekannten Verfahren der Vliesherstellung, wie sie beispielsweise in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A 17, VCH Weinheim 1994, Seiten 572 - 581, beschrieben werden, hergestellt werden. Nonwovens may be prepared by all methods of nonwoven production known in the art, as described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A 17, VCH Weinheim 1994, pages 572-581.
Bevorzugt sind dabei Vliese, die entweder nach dem sogenannte "dry laid"- oder dem Spinnvlies- bzw. spunbond-Verfahren oder im melt-blow-Verfahren(schmelzgesponnen) hergestellt wurden. Das "dry laid"-Verfahren geht von Stapelfasern aus, die üblicherweise durch Kardieren in Einzelfasern getrennt und anschließend unter Einsatz eines ärodynamischen oder hydrodynamischen Verfahrens zum unverfestigten Vliesstoff zusammengelegt werden. Dieser wird dann beispielsweise durch eine thermische Behandlung zum fertigen Vlies verbunden (das sogenannte "thermobonding"). Dabei werden die synthetischen Fasern entweder soweit erwärmt, daß deren Oberfläche schmilzt und die Einzelfasern an den Kontaktstellen miteinander verbunden werden, oder die Fasern werden mit einem Additiv überzogen, welches bei der Wärmebehandlung schmilzt und so die einzelnen Fasern miteinander verbindet. Durch Abkühlung wird die Verbindung fixiert. Neben diesem Verfahren sind natürlich auch alle anderen Verfahren geeignet, die im Stand der Technik zum Verbinden von Vliesstoffen eingesetzt werden. Die Spinnvliesbildung geht dagegen von einzelnen Filamenten aus, die nach dem Schmelzspinnverfahren aus extrudierten Polymeren gebildet werden, welche unter hohem Druck durch Spinndüsen gedrückt werden. Die aus den Spinndüsen austretenden Filamente werden gebündelt, gestreckt und zu einem Vlies abgelegt, welches üblicherweise durch "thermobonding" verfestigt wird. Preference is given to nonwovens, either after the so-called "dry laid" - or Spunbond or spunbond process or melt-blow process (melt-spun) were manufactured. The "dry laid" process is based on staple fibers, which are usually separated by carding into individual fibers and then using an aerodynamic or hydrodynamic process to unconsolidated nonwoven fabric become. This is then for example by a thermal treatment for finished fleece connected (the so-called "thermobonding"). Here are the synthetic Fibers either so far heated that their surface melts and the individual fibers be joined together at the contact points, or the fibers are with an additive coated, which melts during the heat treatment and so the individual Connecting fibers together. By cooling the connection is fixed. Next Naturally, all other processes suitable in the state of the art are also suitable for this process Technology used to join nonwovens. The spunbonding works on the other hand, of individual filaments extruded by the melt-spinning process Polymers are formed, which are pressed under high pressure through spinnerets become. The emerging from the spinneret filaments are bundled, stretched and deposited into a nonwoven, which is usually solidified by "thermobonding" becomes.
Für kosmetische Anwendungen wird eine Imprägnierung hydrophilierter poleolefinhaltiger Vliese mit O/W oder W/O-Emulsionen geeignet. Durch die Kombination der hydrophilierten polyolefinhaltigen Vliese mit einer Imprägnierung mit einer Emulsion können 2-Phasen-Reinigungstücher produziert werden, die zunächst ein kühlendes/reinigendes Gefühl auf der Haut erzeugen um zuletzt einen cremenden Effekt auf der Haut hinterlassen. Dieser Effekt ist nicht nur bei Spinnvliesen, sondern auch bei kardierten Vliesen, die hydrophilierte Polypropylen-Stapelfasern enthalten, zu beobachten. Ein weiterer Vorteil dieser kosmetischen Tücher ist das geringe Ausbluten in übereinandergestapelten Tüchern oder Vliesen. Es wurde überraschender Weise festgestellt, dass bei der Anwendung der hydrophilierten Polyolefinhaltigen Tücher in Kombination mit Emulsionen als Imprägnierung auch bei längerer Lagerung kein Absinken der äußeren Phase - Öl oder Wasser - innerhalb des Kosmetiktuch- oder Wipe-Stapels zu beobachten ist.For cosmetic applications, an impregnation of hydrophilic Pololeolefinhaltiger Nonwovens with O / W or W / O emulsions suitable. By combining the hydrophilized polyolefin-containing nonwovens impregnated with an emulsion 2-phase cleaning wipes can be produced, which are initially a cooling / cleansing Feeling on the skin produce a creamy effect on the last Leave skin behind. This effect is not only with spunbonded nonwovens but also with carded ones Nonwovens containing hydrophilized polypropylene staple fibers can be observed. One Another advantage of these cosmetic towels is the low bleeding in stacked Towels or fleeces. It was surprisingly found that at the Application of the hydrophilized polyolefin-containing cloths in combination with emulsions as impregnation, even during prolonged storage no decrease in the outer phase - oil or water - within the tissue or wipe stack.
