Description
Die Erfindung bezieht sich auf künstliches Haar für die Haarimplantation oder für Haarersatzteile, wie Perücke, Haarteil, Toupet aus einem extrudierten und verstreckten Monofil auf Basis sterilisierbarer thermoplastischer Kunststoffe, enthaltend Farbmittel.The invention relates to artificial hair for the Hair implantation or for hair replacement parts, such as wigs, Hairpiece, toupee made of an extruded and stretched Monofilament based on sterilizable thermoplastic Plastics containing colorants.
Es ist bekannt, künstliche Haare für Haarersatzteile bzw. zu implantierende Haare aus Polyamid, Polyvinylchlorid, Polypropylen, Polyethylen, Polyacrylnitril, Polyurethan bzw. Polyester als thermoplastischem Kunststoff durch Schmelzspinnen oder Naßspinnen, gegebenenfalls mit nachfolgendem Verstrecken, herzustellen, wozu beispielsweise auf die DE-OS 38 00 074, DE-OS 25 23 127, DE-OS 39 23 918, DE-OS 35 15 114, DE-OS 34 31 886, DE-AS 28 33 693, DE-GM 88 06 904, DE-GM 87 06 427, DE-GM 89 07 506 und DE-GM 89 13 458 verwiesen wird.It is known to use artificial hair for hair replacement parts too implanting hair made of polyamide, polyvinyl chloride, Polypropylene, polyethylene, polyacrylonitrile, polyurethane or Polyester as thermoplastic by melt spinning or wet spinning, possibly with subsequent drawing, to produce, for example on DE-OS 38 00 074, DE-OS 25 23 127, DE-OS 39 23 918, DE-OS 35 15 114, DE-OS 34 31 886, DE-AS 28 33 693, DE-GM 88 06 904, DE-GM 87 06 427, DE-GM 89 07 506 and DE-GM 89 13 458 referenced becomes.
An künstliche Haare, die aus Kunststoffäden aus Monofilen aus thermoplastischem Kunststoff bestehen, werden hohe Anforderungen bezüglich Sterilisierbarkeit, Sauberkeit, Hautverträglichkeit, Beständigkeit, Einfärbbarkeit, Lichtechtheit, Modellierbarkeit, Geschmeidigkeit, Flammfestigkeit bzw. Brandfestigkeit gestellt. Keiner der für künstliches Haar eingesetzten thermoplastischen Kunststoffe erfüllt alle diese geforderten Eigenschaften, vielmehr werden die Kunststoffe, wie die angeführten Druckschriften beschreiben, durch Zusätze, wie Weichmacher, Flammschutzmittel, Stabilisatoren oder zusätzliche Behandlungen, wie chemisches Aufrauhen, modifiziert, um das künstliche Haar dem geforderten Eigenschaftsbild anzunähern.On artificial hair made from monofilament plastic threads thermoplastic plastic, high demands regarding sterilizability, cleanliness, skin tolerance, Durability, colorability, lightfastness, modeling, Suppleness, flame resistance or fire resistance. None of the thermoplastic used for artificial hair Plastics fulfills all of these required properties, rather, the plastics, like the ones mentioned Describe publications using additives such as plasticizers, Flame retardants, stabilizers or additional Treatments, such as chemical roughening, are modified to accommodate this to bring artificial hair closer to the required property profile.
Der Erfindung liegt die Aufgabe zugrunde, ein neues nicht resorbierbares qualifiziertes künstliches Haar mit einer guten Einfärbbarkeit und Modellierbarkeit sowie hoher Brandfestigkeit zu schaffen.The invention is based, not a new one absorbable qualified artificial hair with a good Colorability and modeling, as well as high fire resistance to accomplish.
Diese Aufgabe wird gemäß Kennzeichen des Anspruches 1 durch Verwendung von Monofilen auf Basis Polyvinylidenfluorid (PVDF) als thermoplastischem Kunststoff als künstliches Haar gelöst.This object is achieved by the characterizing part of claim 1 Use of monofilaments based on polyvinylidene fluoride (PVDF) solved as a thermoplastic synthetic hair.
Polyvinylidenfluorid gehört zur Gruppe der fluorhaltigen Polymere, die bisher keine Verwendung als künstliches Haar gefunden haben, obgleich sie sich durch Unbrennbarkeit, Wetterfestigkeit und physiologische Indifferenz auszeichnen.Polyvinylidene fluoride belongs to the group of fluorine-containing Polymers that have not yet been used as artificial hair have found themselves, despite being non-flammable, Characterize weather resistance and physiological indifference.
Polyvinylidenfluorid ist jedoch schwierig wegen des hohen Schmelzpunktes, wie auch andere fluorhaltige Polymere, zu verarbeiten. Die fluorhaltigen Polymere werden bevorzugt wegen ihrer ausgezeichneten elektrischen Werte und hohen mechanischen Festigkeiten industriell eingesetzt, wobei PVDF als hochkristalliner steifer Werkstoff bevorzugt im Rohrleitungs- und Apparatebau verwendet wird. Aus der EP 01 33 001 sind Vinylidenfluoridharzfasern für die industrielle Verwendung für Seile, Gewebe, Angelschnüre, Saiten für Musikinstrumente bekannt, aus der DE-OS 32 07 502 auch die Verwendung von Vinylidenfluoridharzmonofilen als Tennissaiten, aus der DE-OS 24 27 394 die Verwendung von aus Lösungen gesponnenen Polyvinylidenfluoridfasern zum Herstellen von Textilerzeugnissen. Des weiteren ist aus der DE-OS 30 45 333 die Verwendung von Fibriden aus PVDF als Substitutionsprodukt für Zellstoff zur Papier- und Filterherstellung bekannt. Des weiteren ist gemäß DE-PS 32 28 428 auch bereits die Verwendung von PVDF-Monofilen als chirurgisches Nahtmaterial vorgeschlagen worden.However, polyvinylidene fluoride is difficult because of the high Melting point, as well as other fluorine-containing polymers to process. The fluorine-containing polymers are preferred because of their excellent electrical values and high mechanical Strengths used industrially, whereby PVDF as highly crystalline rigid material preferred in piping and apparatus construction is used. From EP 01 33 001 Vinylidene fluoride resin fibers for industrial use for Ropes, fabrics, fishing lines, strings for musical instruments known from DE-OS 32 07 502 also the use of Vinylidene fluoride resin monofilaments as tennis strings from which DE-OS 24 27 394 the use of spun from solutions Polyvinylidene fluoride fibers for the production of Textile products. Furthermore, from DE-OS 30 45 333 the use of fibrids from PVDF as a substitute product known for pulp for paper and filter manufacture. Of further is according to DE-PS 32 28 428 also the use proposed by PVDF monofilaments as surgical sutures been.
Überraschend wurde nun gefunden, daß Polyvinylidenfluorid, obwohl wegen seiner hervorragenden mechanischen Eigenschaften sowie Temperaturfestigkeit als Konstruktionswerkstoff bevorzugt bekannt, sich auch in Gestalt von Monofilen zum Einsatz als künstliches Haar eignet. Hierbei weisen die künstlichen Haare gemäß der Erfindung aus Monofilen auf Basis Polyvinylidenfluorid nicht nur hohe Reißkraft, sondern auch eine ausreichend hohe Geschmeidigkeit und glatte Oberfläche neben einer geringen Dehnung auf. Vor allem zeigen die Monofile auf Basis PVDF eine geringe Neigung zum Aufspleißen. Unter Monofilen auf Basis PVDF werden solche verstanden, die mindestens 50 Gew.-% Polyvinylidenfluorid enthalten, wobei neben PVDF weitere Anteile mit PVDF kompatibler thermoplastischer Kunststoffe, wie beispielsweise Copolymere des Vinylidenfluorids enthalten sein können. Eine weitere vorteilhaft sich auswirkende Eigenschaft des PVDF ist die Unbrennbarkeit und hohe Wetterfestigkeit und die physiologische Indifferenz. Auch ist PVDF hoch strahlungsbeständig. Alle diese Eigenschaften des PVDF wirken sich besonders vorteilhaft bei dem erfindungsgemäßen Einsatz in Gestalt extrudierter verstreckter Monofile für künstliche Haare in Gestalt von Haarersatzteilen aus. Des weiteren lassen sich die künstlichen Haare aus PVDF-Monofilen einwandfrei für die Haarprothetik zu Haarersatzteilen verarbeiten, wie Perücken, Toupets, Haarteile.Surprisingly, it has now been found that polyvinylidene fluoride, although because of its excellent mechanical properties as well as temperature resistance preferred as a construction material known to also be used in the form of monofilaments artificial hair is suitable. Here, the artificial hair based on the invention from monofilaments Polyvinylidene fluoride not only has high tensile strength, but also a sufficiently high suppleness and smooth surface in addition to a slight stretch. Above all, the monofilaments show based on PVDF a slight tendency to unravel. Under Monofilaments based on PVDF are understood to be those that contain at least 50 wt .-% polyvinylidene fluoride, wherein in addition to PVDF, other parts more compatible with PVDF thermoplastics, such as copolymers of vinylidene fluoride can be included. Another the property of PVDF which has an advantageous effect is Incombustibility and high weather resistance and the physiological Indifference. PVDF is also highly radiation-resistant. All these Properties of the PVDF have a particularly advantageous effect the use according to the invention in the form of extruded stretched monofilament for artificial hair in the form of Hair replacement parts. Furthermore, the artificial Hair made of PVDF monofilament perfect for prosthetic hair too Process hair replacement parts, such as wigs, toupees, hair pieces.
Es ist wünschenswert, die künstlichen Haare, PVDF ist von Natur aus farblos, auch in üblichen Haarfarben zu erhalten. Zu diesem Zweck wird vorgeschlagen, daß die Monofile eingefärbt sind, wobei die Monofile neben PVDF ein lebensmittelrechtlich zugelassenes und hautverträgliches Farbmittel enthalten, und diese Farbmittel gegebenfalls auf Trägermaterialien aufgebracht und dem PVDF vor der Extrusion zu Monofilen zugegeben werden. Als Trägermaterialien wird ein mit dem PVDF verträglicher thermoplastischer Kunststoff eingesetzt. Insgesamt sind nur geringe Mengen an Farbmittel bzw. Farbmittel und Trägermaterial, vorzugsweise unter 2 Gew.-%, bezogen auf PVDF, in dem Monofil enthalten. Weiterhin zeichnen sich die erfindungsgemäßen Haarersatzteile durch UV-Beständigkeit aus. It is desirable the artificial hair, PVDF is natural made of colorless, also available in normal hair colors. To this Purpose it is suggested that the monofilaments are colored, the monofilament is a food law in addition to PVDF contain approved and skin-friendly colorant, and these colorants optionally applied to carrier materials and added to the PVDF before extrusion into monofilaments. The carrier materials become compatible with the PVDF thermoplastic used. Overall are only small amounts of colorant or colorant and Carrier material, preferably below 2% by weight, based on PVDF, included in the monofilament. Furthermore, the Hair replacement parts according to the invention from UV resistance.
Das künstliche Haar aus PVDF weist einen Durchmesser der Monofile von etwa 0,05 bis 0,1 mm auf und wird in den gewünschten Haarlängen angeboten. Die Monofile weisen vorzugsweise Längen von etwa 10 bis 30 cm auf und werden dann zum Beispiel zu Haarersatzteilen verarbeitet.The artificial hair made of PVDF has a diameter of Monofilament from about 0.05 to 0.1 mm and is in the desired hair lengths offered. The monofilaments show preferably lengths of about 10 to 30 cm and then processed into hair replacement parts, for example.
Die Modellierbarkeit der PVDF-Monofile wird durch ihre Verstreckung verbessert, wobei die Monofile, die durch Extrusion hergestellt werden, unmittelbar nach der Extrusion im Verhältnis von etwa 1 : 3 bis 1 : 8 verstreckt werden. Bevorzugt werden die PVDF-Monofile im Verhältnis von etwa 1 : 4 bis 1 : 6 verstreckt.The ability to model PVDF monofilaments is determined by their Stretching improves, with the monofilament passing through Extrusion can be made immediately after extrusion in the Ratio of about 1: 3 to 1: 8 stretched. Prefers the PVDF monofilaments in a ratio of about 1: 4 to 1: 6 stretched.
Als Farbmittel werden beispielsweise die aus dem Colour Index ausgewählten Pigmente Yellow 148, Pigment Brown 6, Pigment Black 7, Pigment White 6, einzeln oder in Abmischungen eingesetzt.Colorants are, for example, those from the Color Index selected pigments Yellow 148, Pigment Brown 6, pigment Black 7, Pigment White 6, individually or in mixtures used.
Die Erfindung ist in der Zeichnung in der einzigen Figur beispielhaft dargestellt.The invention is in the drawing in the single figure shown as an example.
In der einzigen Figur ist ein künstliches Haar 1 dargestellt, das aus einem extrudierten und 1 : 5-fach verstreckten Monofil aus PVDF mit geringen Anteilen Pigment Brown 6 nach Colour Index besteht, einen Durchmesser von 0,06 mm aufweist und eine Länge von 30 cm hat. Nach der Verarbeitung zu einer Perücke kann das Haar modelliert, beispielsweise mit Wellen versehen werden, gewaschen und allen üblichen Behandlungen unterworfen werden.In the single figure, an artificial hair 1 is shown, which consists of an extruded and 1: 5 times stretched monofilament made of PVDF with small proportions of Pigment Brown 6 according to Color Index, has a diameter of 0.06 mm and a length of 30 cm Has.
