Beschreibungdescription
Die Erfindung betrifft Schlafwäsche, bestehend aus einem Mikrofilament- Vliesstoff mit Flächengewichten von 70 bis 150g/m2 und einem Partikelrückhaltevermögen >90% für Partikelteilchen < 0,5 μm.The invention relates to sleepwear consisting of a microfilament nonwoven fabric with basis weights of 70 to 150g / m 2 and a particle retention capacity> 90% for particle particles <0.5 μm.
Ein nicht unbeträchtlicher Teil der Bevölkerung leidet an durch Hausstaubmilben hervorgerufenen Allergien. Dabei bieten insbesondere die Polsterung von Matratzen, Kopfkissen und Bettdecken ideale Brutstätten für Hausstaubmilben, da Milben sich in das Innere zurückziehen können und so einer dauerhaften Entfernung durch das Waschen der Bezugsstoffe wie Bettwäsche und Bettlaken entgehen. Es ist daher bereits vorgeschlagen worden, die Bezugsstoffe mit akariziden Wirkstoffen auszurüsten. Nachteilig dabei ist, daß die Wirkstoffe durch die aus hygienischen Gründen notwendigen Waschvorgänge sehr schnell wieder entfernt werden. Ein weiterer Vorschlag besteht darin, eine dichte Folie auf einen Bezugstoff aufzubringen. Dadurch wird jedoch der Feuchtigkeitstransport verhindert und Schweiß kann nicht mehr abgeleitet werden.A not inconsiderable part of the population suffers from allergies caused by dust mites. The upholstery of mattresses, pillows and duvets in particular offers ideal breeding grounds for dust mites, since mites can retreat to the inside and thus avoid permanent removal by washing the cover fabrics such as bed linen and sheets. It has therefore already been proposed to provide the upholstery fabrics with acaricidal active ingredients. The disadvantage here is that the active ingredients are very quickly removed again by the washing processes necessary for hygienic reasons. Another proposal is to apply a dense film to a cover fabric. However, this prevents moisture transport and sweat can no longer be drained off.
Aus den Dokument US 5,050,256 und US 5,950,264 sind antiallergene Bezugsstoffe bekannt, bei denen eine Polyurethanschicht auf ein Trägermaterial auflaminiert ist. Die Polyurethanschicht soll dabei dem Material eine Porengröße < 10μm bei gleichzeitig noch vorhandener Wasserdampfdurchlässigkeit verleihen. Die Erfindung hat sich die Aufgabe gestellt, preiswerte Schlafwäsche, die ein hohes Partikelrückhaltevermögen bei einem geringen Gewicht besitzt sowie ein Verfahren zu deren Herstellung anzugeben.From US Pat. Nos. 5,050,256 and 5,950,264, anti-allergenic coverings are known in which a polyurethane layer is laminated onto a carrier material. The polyurethane layer is said to give the material a pore size of <10 μm with simultaneous water vapor permeability. The invention has set itself the task of providing inexpensive sleepwear that has a high particle retention capacity at a low weight and a method for its production.
Erfindungsgemäß wird die Aufgabe durch Schlafwäsche gelöst, welche aus einem Vliesstoff mit Flächengewichten von 70 bis 150 g/m2 und einem Partikelrückhaltevermögen >90% für Partikelteilchen < 0,5 μm besteht, wobei der Vliesstoff aus schmelzgesponnenen, verstreckten und unmittelbar zu einem Vlies abgelegten Mehrkomponenten-Endlosfilamenten mit einem Titer von 1 ,5 bis 5dtex besteht und die Mehrkomponenten-Endlosfilamente gegebenenfalls nach einer Vorverfestigung zumindest zu 80% zu Mikro-Endlosfilamenten mit einem Titer von 0,1 bis 0,8 dtex gesplittet und verfestigt sind. Eine solche Schlafwäsche weist bei einem vergleichsweise geringen Gewicht ein Partikelrückhaltevermögen >90% für Partikelteilchen < 0,5 μm auf und ist daher als Allergikerschlafwäsche insbesondere gegenüber Hausstaubmilben und deren Absonderungen geeignet.According to the invention, the object is achieved by sleepwear, which consists of a nonwoven fabric with basis weights of 70 to 150 g / m 2 and a particle retention capacity> 90% for particle particles <0.5 μm, the nonwoven fabric being melt-spun, stretched and immediately deposited into a nonwoven fabric Multicomponent continuous filaments with a titer of 1.5 to 5 dtex exist and the multicomponent continuous filaments are optionally split and consolidated at least 80% into micro continuous filaments with a titer of 0.1 to 0.8 dtex after pre-consolidation. Such sleepwear, with a comparatively low weight, has a particle retention capacity> 90% for particle particles <0.5 μm and is therefore particularly suitable as allergy-free sleepwear for house dust mites and their secretions.
Vorzugsweise ist die Schlafwäsche eine, bei der der Vliesstoff aus schmelzgesponnenen, verstreckten und unmittelbar zu einem Vlies abgelegten Mehrkomponenten-Endlosfilamenten mit einem Titer von 2 bis 3 dtex besteht und die Mehrkomponenten-Endlosfilamente zumindest zu 80 % zu Mikro- Endlosfilamenten mit einem Titer von 0,1 bis 0,3 dtex gesplittet und verfestigt sind.The sleepwear is preferably one in which the nonwoven fabric consists of melt-spun, drawn and immediately deposited multi-component continuous filaments with a titer of 2 to 3 dtex, and the multi-component continuous filaments are at least 80% micro-continuous filaments with a titer of 0 , 1 to 0.3 dtex are split and solidified.
Vorzugsweise ist die Schlafwäsche eine, bei der das Mehrkomponenten- Endlosfilament ein Bikomponenten-Endlosfilament aus zwei inkompatiblen Polymeren, insbesondere einem Polyester und einem Polyamid, ist. Ein solches Bikomponenten-Endlosfilament weist eine gute Spaltbarkeit in Mikro- Endlosfilamenten auf und bewirkt ein günstiges Verhältnis von Festigkeit zu Flächengewicht auf. Vorzugsweise ist die Schlafwäsche eine, bei der die Mehrkomponenten- Endlosfilamente einen Querschnitt mit orangenartiger oder auch „Pie" genannten Multisegment-Struktur aufweisen, wobei die Segmente alternierend jeweils eines der beiden inkompatiblen Polymeren enthalten. Neben dieser orangenartigen Multisegment-Struktur der Mehrkomponenten-Endlosfilamente ist auch eine „side-by-side" (s/s) Anordnung der inkompatiblen Polymeren im Mehrkomponenten-Endlosfilament möglich, die vorzugsweise zur Erzeugung gekräuselter Filamente genutzt wird. Solche Anordnungen der inkompatiblen Polymeren im Mehrkomponenten-Endlosfilament haben sich als sehr gut spaltbar erwiesen.The sleepwear is preferably one in which the multi-component continuous filament is a bicomponent continuous filament composed of two incompatible polymers, in particular a polyester and a polyamide. Such a bicomponent filament has good cleavage in micro filaments and brings about a favorable ratio of strength to basis weight. The sleepwear is preferably one in which the multicomponent continuous filaments have a cross section with an orange-like or also called “pie” multisegment structure, the segments alternately each containing one of the two incompatible polymers. In addition to this orange-like multisegment structure, the multicomponent continuous filaments a “side-by-side” (s / s) arrangement of the incompatible polymers in the multicomponent continuous filament is also possible, which is preferably used to produce crimped filaments. Such arrangements of the incompatible polymers in the multicomponent continuous filament have proven to be very easy to split.
Vorzugsweise ist die Schlafwäsche weiterhin eine, bei der mindestens eines der das Mehrkomponenten-Endlosfilament bildenden inkompatiblen Polymeren ein Additiv, wie Farbpigmente, permanent wirkende Antistatika und/oder die hydrophilen oder hydrophoben Eigenschaften beeinflussende Zusätze in Mengen bis zu 10 Gewichtsprozent, enthält. Die aus spinngefärbten Fasern bestehende Schlafwäsche weist eine sehr gute Waschechtheit auf. Weiterhin können durch die Zusätze statische Aufladungen vermindert bzw. vermieden und die Feuchtigkeits-Transporteigenschaften verbessert werden.The sleepwear is preferably also one in which at least one of the incompatible polymers forming the multicomponent continuous filament contains an additive, such as color pigments, permanent antistatic agents and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 10% by weight. The sleepwear made of spun-dyed fibers has a very good fastness to washing. Furthermore, the additives can reduce or avoid static charges and improve the moisture transport properties.
Vorzugsweise ist die Schlafwäsche weiterhin eine, die punktkalandriert ist. Eine solche Gestaltung der Oberfläche verbessert die Abriebbeständigkeit.The sleepwear is preferably also one that is point calendered. Such a design of the surface improves the abrasion resistance.
Das erfindungsgemäße Verfahren zur Herstellung einer Schlafwäsche besteht darin, daß Mehrkomponenten-Endlosfilamente aus der Schmelze ersponnen, verstreckt und unmittelbar zu einem Vlies abgelegt werden, eine Vorverfestigung erfolgt und der Vliesstoff durch Hochdruck-Fluidstrahlen verfestigt wie gleichzeitig in Mikro-Endlosfilamente mit einem Titer von 0,1 bis 0,8 dtex gesplittet wird. Die so erhaltene Schlafwäsche ist sehr gleichmäßig hinsichtlich ihrer Dicke, sie weist eine isotrope Fadenverteilung auf, besitzt keine Neigung zum Delaminieren und ist durch hohe Modulwerte ausgezeichnet.The process according to the invention for producing a sleepwear consists in spinning multicomponent continuous filaments from the melt, stretching them and laying them down immediately to form a nonwoven fabric, pre-consolidating them and solidifying the nonwoven fabric by high-pressure fluid jets, as in micro-continuous filaments with a titer of 0 , 1 to 0.8 dtex is split. The sleepwear obtained in this way is very uniform in terms of its thickness and has an isotropic thread distribution no tendency to delaminate and is characterized by high module values.
Vorteilhafterweise wird das Verfahren zur Herstellung der Schlafwäsche in der Weise durchgeführt, daß die Verfestigung und Splittung der Mehrkomponenten- Endlosfilamente dadurch erfolgt, daß der gegebenenfalls vorverfestigte Vliesstoff mindestens einmal auf jeder Seiten mit Hochdruck-Wasserstrahlen beaufschlagt wird. Die Schlafwäsche weist dadurch eine gute Oberfläche und einen Splittungsgrad der Mehrkomponenten-Endlosfilamente > 80% auf.The process for producing the sleepwear is advantageously carried out in such a way that the solidification and splitting of the multicomponent continuous filaments takes place in that the optionally pre-consolidated nonwoven fabric is subjected to high-pressure water jets at least once on each side. As a result, the sleepwear has a good surface and a degree of splitting of the multi-component continuous filaments> 80%.
Besonders bevorzugt ist ein Verfahren, bei dem die Mehrkomponenten- Endlosfilamente spinngefärbt werden. Die Einbindung des Farbstoffe in die Polymerfasern führt zu hervorragenden Waschechtheiten.A method is particularly preferred in which the multicomponent continuous filaments are spin-dyed. The integration of the dyes in the polymer fibers leads to excellent wash fastness.
Die Abriebbeständigkeit der erfindungsgemäßen Schlafwäsche wird dadurch verbessert, daß die Mikro-Endlosfilamente an den Oberflächen des Vliesstoffes durch ein Thermokalandrierverfahren punktuell mit einander verschweißt werden. Dazu wird der verfestigte und in Mikro-Endlosfilamente gesplittete Vliesstoff durch beheizte Walzen geführt, die Erhebungen besitzen und an diesen Stellen zu einem Verschmelzen der Mikro-Endlosfilamente untereinander führen.The abrasion resistance of the sleepwear according to the invention is improved in that the micro-continuous filaments on the surfaces of the nonwoven fabric are spot welded to one another by a thermal calendering process. For this purpose, the solidified non-woven fabric, which is split into micro-continuous filaments, is passed through heated rollers which have elevations and at these points lead to a fusion of the micro-continuous filaments with one another.
Die erfindungsgemäße Schlafwäsche ist insbesondere geeignet als Bettwäsche und Bettlaken für Allergiker gegen Hausstaubmilben und deren Absonderungen. Daneben besitzt die erfindungsgemäße Schlafwäsche ein gutes Wasseraufnahme- und Wasserableitungsvermögen, das sich in entsprechenden Werten der Wasserdampfpermeabilität und der Kurzzeit- Wasserdampf-Absorptionsfähigkeit bzw. dem Wasserdampfwiderstand äußert. Beispiel 1The sleepwear according to the invention is particularly suitable as bed linen and bed sheets for allergy sufferers against house dust mites and their secretions. In addition, the sleepwear according to the invention has good water absorption and water drainage capacity, which manifests itself in corresponding values for water vapor permeability and short-term water vapor absorption capacity or water vapor resistance. example 1
