Description
Die Erfindung betrifft Schlafwäsche, bestehend aus einem Mikrofilament- Vliesstoff mit Flächengewichten von 70 bis 150 g/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 150 g / m 2 and a particle retention capacity <90% for particle particles <0.5 microns.
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 Dust mite allergies. In particular, the Upholstery of mattresses, pillows and duvets ideal breeding grounds for Dust mites because mites can retreat to the inside and stuff permanent removal by washing the cover fabrics such as Bed sheets and sheets are missed. It is therefore already suggested been equipped with acaricidal active ingredients. Disadvantageous is that the active ingredients are necessary for hygienic reasons Washing operations can be removed very quickly. Another suggestion consists of applying a thick film to a cover fabric. Thereby However, the moisture transport is prevented and sweat can no longer be derived.
Aus den Dokumenten 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 < 10 µm bei gleichzeitig noch vorhandener Wasserdampfdurchlässigkeit verleihen.Documents US 5,050,256 and US 5,950,264 are antiallergenic Reference fabrics known in which a polyurethane layer on a Backing material is laminated on. The polyurethane layer should be the material a pore size <10 µm while still existing Give water vapor permeability.
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.The invention has set itself the task of inexpensive sleepwear, the one has high particle retention with a low weight and a Specify processes for their manufacture.
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 5 dtex besteht und die Mehrkomponenten-Endfosfilamente 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 There are multi-component continuous filaments with a titer of 1.5 to 5 dtex and the multi-component endfos 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 of <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, aerodynamisch verstreckten und unmittelbar zu einem Vlies abgelegten Mehrkomponenten-Endlosfilamenten mit einem Titer von 2 bis 3 dtex besteht und die Mehrkomponenten-Endlosfilamente gegebenenfalls nach einer Vorverfestigung 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 is made of melt-spun, aerodynamically stretched and immediately deposited into a fleece Multicomponent continuous filaments with a titer of 2 to 3 dtex and the multicomponent filaments optionally after one Pre-consolidation at least 80% to micro-continuous filaments with a titer from 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. The sleepwear is preferably one in which the multi-component Continuous filament is a bicomponent continuous filament made of two incompatible Polymers, especially a polyester and a polyamide. Such one Bicomponent continuous filament has good cleavage in micro Continuous filaments and creates a favorable ratio of strength to Basis weight.
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 filaments a cross section with orange or "pie" have said multi-segment structure, the segments alternating each contain one of the two incompatible polymers. Besides this orange-like multi-segment structure of the multi-component continuous filaments is also a "side-by-side" (s / s) arrangement of the incompatible polymers in the Multi-component continuous filament possible, preferably for production crimped filaments is used. Such arrangements of the incompatible Polymers in the multi-component continuous filament have proven to be very good proven fissile.
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 the multi-component continuous filament incompatible polymer Additive, such as color pigments, permanent antistatic agents and / or additives influencing hydrophilic or hydrophobic properties in Amounts up to 10 percent by weight. The spun-dyed fibers existing sleepwear has a very good fastness to washing. Farther can be reduced or avoided by the addition of static charges and the moisture transport properties are improved.
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. A 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 so 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 method according to the invention for producing a sleepwear consists in that multi-component continuous filaments are spun from the melt, stretched and immediately deposited into a fleece, one Pre-consolidation takes place and the nonwoven fabric by high pressure fluid jets solidifies in the same way as in continuous micro filaments with a titer of 0.1 to 0.8 dtex is split. The sleepwear obtained in this way is very even in terms of its thickness, it has an isotropic thread distribution no tendency to delaminate and is due to high module values excellent.
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 Seite mit Hochdruck-Wasserstrahlen beaufschlagt wird. Die Schlafwäsche weist dadurch eine gute Oberfläche und einen Splittungsgrad der Mehrkomponenten-Endlosfilamente < 80% auf.The method for producing the sleepwear is advantageously used in the Carried out in such a way that the solidification and splitting of the multi-component Endless filaments take place in that the possibly pre-consolidated Nonwoven fabric at least once on each side with high pressure water jets is applied. The sleepwear has a good surface and a degree of splitting of the multicomponent 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 multi-component Continuous filaments are spin-dyed. The integration of the dyes in the Polymer fibers lead 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 thereby improves that the micro continuous filaments on the surfaces of the nonwoven fabric spot welded to one another using a thermal calendering process become. For this purpose, the solidified and split into micro continuous filaments Non-woven fabric passed through heated rollers that have bumps and on these points to a fusion of the micro endless filaments lead among themselves.
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.The sleepwear according to the invention is particularly suitable as bed linen and bed sheets for allergy sufferers against dust mites and their Secretions. In addition, the sleepwear according to the invention has one good water absorption and drainage capacity, which is reflected in corresponding values of water vapor permeability and short-term Water vapor absorbency or water vapor resistance.
Aus einem Polyester-Polyamid (PES-PA)-Bikomponenten-Endlosfilament wird ein Filamentflor mit einem Flächengewicht von 154 g/m2 erzeugt und einer Wasserstrahlvernadelung mit Drücken bis 250 bar beidseitig unterzogen. Die Bikomponenten-Endlosfilamente weisen nach der Wasserstrahlvernadelung, die zu einer gleichzeitigen Splittung der Ausgangsfilamente führt, einen Titer von 0,1 bis 0,8 dtex auf. Die Schlafwäsche weist einen Wasserdampfdurchgangsindex imt von 0,45, eine Kurzzeit- Wasserdampfaufnahmefähigkeit von 0,8 und einen Wasserdampfdurchgangswiderstand Ret von 3,49 m2Pa/W auf. Das mit einem optischen Auswerteverfahren ermittelte Partikelrückhaltevermögen zeigt, daß ca. 80% der die Schlafwäsche durchdringenden Partikel < 0,5 µm sind, wobei die Gesamtzahl der durchgedrungenen Partikel pro 100 µm2 ca. 100 beträgt.A filament pile with a basis weight of 154 g / m 2 is produced from a polyester-polyamide (PES-PA) bicomponent filament and subjected to water jet needling at pressures of up to 250 bar on both sides. The bicomponent continuous filaments have a titer of 0.1 to 0.8 dtex after the water jet needling, which leads to a simultaneous splitting of the starting filaments. The sleepwear has a water vapor transmission index i mt of 0.45, a short-term water vapor absorption capacity of 0.8 and a water vapor transmission resistance R et of 3.49 m 2 Pa / W. The particle retention capacity determined using an optical evaluation method shows that approximately 80% of the particles that penetrate the sleepwear are <0.5 μm, the total number of particles penetrated per 100 μm 2 being approximately 100.
