Haarimplantat aus KunststoffädenHair implant made of synthetic threads
Die Neuerung bezieht sich auf ein Haarimplantat aus Kunststoffäden . An Haarimplantäte aus Kunststoffäden werdenThe innovation relates to a hair implant made of synthetic threads. Hair implants made of synthetic threads are

Hautverträglichkeit, Beständigkeit und Model 1ierbarkeit gestellt. Es sind bereits nicht resorbierbare Nahtmaterialien aus thermoplastischen Kunststoffen, wie Polyamiden, Polyestern, Polyolefinen, Polytetrafluorethylen, Polyvinylidenfluorid oder Copolymeren von Vinylidenfluorid bekannt, wozu nur beispielsweise auf die EP-PS 0101 818, die US-PS 4034 763 und EP-OS 0165 500 verwiesen wird.Skin compatibility, durability and modelability. Non-absorbable suture materials made of thermoplastics such as polyamides, polyesters, polyolefins, polytetrafluoroethylene, polyvinylidene fluoride or copolymers of vinylidene fluoride are already known, for example EP-PS 0101 818, US-PS 4034 763 and EP-OS 0165 500.
Der Neuerung liegt die Aufgabe zugrunde, ein nicht resorbierbares qualifiziertes Haarimplantat mit einer guten Einfärbbarkeit und Model 1ierbarkeit sowie hoher Brandfestigkeit zu schaffen.The innovation is based on the task of creating a non- resorbable qualified hair implant with good colorability and modelability as well as high fire resistance.
Diese Aufgabe wird gemäß der Neuerung mit einem Haar implantatThis task is carried out according to the innovation with a hair implant

verstreckten und eingefärbten Monofilen einer endlichen Länge aus Polyvinylidenfluorid gelöst. Monofile aus Polyvinylidenfluorid - PVDF - zeichnen sich nicht nur durch eine Reißkraft, sondern auch eine große Geschmeidigkeit und glatte Oberfläche bei geringer Dehnung aus. Des weiteren zeigen 5drawn and dyed monofilaments of a finite length made of polyvinylidene fluoride. Monofilaments made of polyvinylidene fluoride - PVDF - are not only characterized by a tensile strength, but also by great flexibility and a smooth surface with little stretch. Furthermore, 5
sie eine sehr geringe Neigung zum Aufspleißen. Unter Monofilen aus PVDF werden neuerungsgemäß auch solche verstanden, die austhey have a very low tendency to split. According to the new regulations, monofilaments made of PVDF also include those made of
-4-mindestens 50 Gew.-% Polyvinylidenfluorid bestehen, wobei-4-at least 50 wt.% polyvinylidene fluoride, where
* weitere Anteile hiermit kompatibler thermoplastischer Kunststoffe, wie beispielsweise Copolymere des Vinylidenfluorid, enthalten sein können. Eine weitere vorteilhaft sich auswirkende Eigenschaft des PVDF ist seine Unbrennbarkeit und hohe Wetterfestigkeit und die physiologische Indifferenz. Auch ist PVDF hoch strahlungsbeständig. Alle diese Eigenschaften des PVDF wirken sich besonders vorteilhaft bei dem neuerungsgemäßen Einsatz in Gestalt extrudierter verstreckter Monofile als Haarimplantat aus.* other proportions of compatible thermoplastics, such as vinylidene fluoride copolymers, can be included. Another advantageous property of PVDF is its non-flammability and high weather resistance and physiological indifference. PVDF is also highly resistant to radiation. All of these properties of PVDF are particularly advantageous when used in the form of extruded, stretched monofilaments as hair implants.
Es ist wünschenswert, das Haarimplantat, 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 1ebensmittelrecht 1ich zugelassenes und hautverträgliches Farbmittel enthalten, wobei diese Farbmittel gegebenenfalls auf Trägermaterialien aufgebracht und dem PVDF zugegeben sind und diese Trägermaterialien ein mit dem PVDF verträglicher thermoplastischer Kunststoff sind. 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 neuerungsmäßgen Haarimplantate durch UV-Beständigkeit aus. Die Monofile aus PVDF als Haarimplantat weisen Durchmsser von etwa 0,05 bis 0,1 rnm auf und werden in den gewünschten Haarlängen angeboten, vorzugsweise mit Längen von etwa 10 bis 30 cm.It is desirable to obtain the hair implant, PVDF is naturally colorless, in common hair colors. For this purpose, it is proposed that the monofilaments be colored, whereby the monofilaments contain, in addition to PVDF, a colorant that is approved under food law and is skin-friendly, whereby these colorants are optionally applied to carrier materials and added to the PVDF and these carrier materials are a thermoplastic that is compatible with the PVDF. Overall, only small amounts of colorant or colorant and carrier material, preferably less than 2% by weight, based on PVDF, are contained in the monofilament. The new hair implants are also characterized by UV resistance. The monofilaments made of PVDF as hair implants have diameters of about 0.05 to 0.1 mm and are offered in the desired hair lengths, preferably with lengths of about 10 to 30 cm.
Die Model 1ierbarkeit der Monofile wird auch durch ihre Verstreckung erreicht, wobei die Monofile, die durch Extrusion hergestellt werden, unmittelbar nach der Extrusion im Verhältnis von etwa 1:3 bis 1:6 verstreckt werden.The moldability of the monofilaments is also achieved by their stretching, whereby the monofilaments produced by extrusion are stretched immediately after extrusion in a ratio of about 1:3 to 1:6.
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 ei ngesetzt.Pigments selected from the Colour Index, such as Yellow 148, Pigment Brown 6, Pigment Black 7 and Pigment White 6, are used as colourants, either individually or in mixtures.

Die Neuerung ist in der Zeichnung in der einzigen Figur beispielhaft dargestellt.The innovation is shown as an example in the only figure in the drawing.
In der einzigen Figur ist das Haarimplantat 1 dargestellt, das aus einem extrudierten und l: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 Implantation kann das Haarimplantat modelliert, bei spielsweise"mit Wellen versehen werden.The only figure shows the hair implant 1, which consists of an extruded and 1:5-fold stretched monofilament made of PVDF with small amounts of Pigment Brown 6 according to the Color Index, has a diameter of 0.06 mm and a length of 30 cm. After implantation, the hair implant can be modeled, for example, given waves.
