Abstract
Description
Die Erfindung betrifft einen Haarkamm aus Kunststoff mit Kammzinken und Kammrücken.The invention relates to a plastic hair comb with comb teeth and comb back.
Beim Kämmen der Haare mit einem Frisierkamm aus Kunststoff werden Haare und Kamm, insbesondere bei Trockenheit, in der Regel völlig unkontrolliert elektrostatisch aufgeladen. Dadurch wird die Frisierbarkeit des Haares beeinträchtigt.When combing the hair with a plastic hairdressing comb, the hair and comb are generally electrostatically charged in a completely uncontrolled manner, especially when it is dry. This affects the hair's stylability.
Die elektrostatische Aufladung des Haars beim Kämmen entsteht durch Reibungselektrizität (triboelektrischer Effekt). Wegen der isolierenden Eigenschaften von Kamm und Haar können die getrennten Ladungen nicht abfließen und führen zu Ladungsansammlungen entgegengesetzter Polarität auf Haar und Kamm. Es läßt sich hierzu eine Spannungsreihe derart aufstellen, daß bei Reibung mit dem in der Reihe folgenden Stoff eine positive Aufladung und bei Reibung mit dem vorangehenden Stoff eine negative Aufladung stattfindet. Nach dem Coehnschen Aufladungsgesetz gilt hierzu für Isolatoren, daß sich der Stoff mit der größeren Dielektrizitätskonstante positiv auflädt.The electrostatic charging of the hair when combing is caused by frictional electricity (triboelectric effect). Because of the insulating properties of comb and hair, the separated charges cannot flow away and lead to charge accumulations of opposite polarity on the hair and comb. For this purpose, a series of voltages can be set up in such a way that there is a positive charge when rubbed with the substance following in the series and a negative charge when rubbed with the preceding substance. According to Coehn's law on charging, it applies to insulators that the substance with the higher dielectric constant charges positively.
Auch wenn einer der in Berührung kommenden Stoffe ein Leiter ist, kann eine Aufladung des anderen Stoffes nicht vollständig verhindert werden, weil die bei Reibung am Leiter auf dem Isolator erzeugten Ladungen dort zumindest zum Teil verbleiben. Insbesondere bei trockener Luft (und trockenem Haar) kann daher selbst bei Verwendung eines Metallkamms oder eines mit Metall beschichteten Kunststoffkamms eine individuell mehr oder weniger starke bzw. störende elektrostatische Aufladung nicht vermieden werden.Even if one of the substances in contact is a conductor, charging of the other substance cannot be completely prevented because the charges generated on the insulator due to friction on the conductor remain there at least in part. Especially with dry air (and dry hair), an individually more or less strong or annoying electrostatic charge cannot be avoided even when using a metal comb or a plastic comb coated with metal.
Der Erfindung liegt die Aufgabe zugrunde, einen Kamm aus Kunststoff zu schaffen, bei dessen Verwendung das Haar in bestimmter Weise, insbesondere nicht merklich bzw. nicht störend, elektrostatisch aufgeladen wird. Bei dem Haarkamm eingangs genannter Art ist die erfindungsgemäße Lösung gekennzeichnet durch den Aufbau aus mindestens einem das Haar beim Kämmen negativ aufladenden Abschnitt und mindestens einem das Haar beim Kämmen positiv aufladenden Abschnitt.The invention has for its object to provide a comb made of plastic, the use of which the hair is electrostatically charged in a certain way, in particular not noticeably or not disruptively. In the case of the hair comb of the type mentioned at the outset, the solution according to the invention is characterized by the structure of at least one section which negatively charges the hair when combing and at least one section which charges the hair positively when combing.
Erfindungsgemäß wird also der Kamm aus Materialien zusammengesetzt, von denen das eine in der eingangs erwähnten Spannungsreihe vor dem Haar und das andere in der Spannungsreihe nach dem Haar steht. Die Erfindung läßt sich unter Bezugnahme auf das Coehnsche Aufladungsgesetz auch so beschreiben, daß der Kamm aus mindestens zwei isolierenden Einzelbereichen zusammenzusetzen ist, wobei das Material des einen Einzelbereichs eine niedrigere Dielektrizitätskonstante als das Haar und das Material des anderen Bereichs eine höhere Dielektrizitätskonstante als das Haar besitzen soll.According to the invention, the comb is thus composed of materials, one of which is in front of the hair in the series of tension mentioned at the beginning and the other is in the series of tension after the hair. The invention can also be described with reference to Coehn's law on charging so that the comb is to be composed of at least two isolating individual areas, the material of one individual area having a lower dielectric constant than the hair and the material of the other area having a higher dielectric constant than the hair should.
Durch den erfindungsgemäßen Einsatz zweier Kunststoffe, welche für sich allein genommen, das Haar beim Kämmen etwa gleich stark, jedoch mit unterschiedlicher Polarität, aufladen, läßt sich eine selbsttätige Neutralisierung der normalerweise beim Kämmen auftretenden elektrostatischen Beladung des Haars erreichen. Vorzugsweise werden das Verhältnis der Volumina und/oder die räumliche Verteilung der beiden Abschnittstypen im Sinne eines gegenseitigen Neutralisierens der von den Abschnitten auf dem Haar erzeugten Ladungen ausgewählt. Bei entsprechender Anpassung von Material, Volumen und räumlicher Verteilung zeigt mit dem erfindungsgemäßen Kamm gekämmtes Haar praktisch keine resultierende elektrostatische Aufladung. Grundsätzlich liegt es aber auch im Rahmen der Erfindung, durch Auswahl der Einzelmaterialien, Volumenverhältnisse und/oder räumlichen Verteilungen der beiden Abschnittstypen eine bestimmte, gewollte elektrostatische Beladung vorzugeben.By using two plastics according to the invention which, taken on their own, charge the hair about the same strength but with different polarity when combing, an automatic neutralization of the electrostatic loading of the hair which normally occurs when combing can be achieved. The ratio of the volumes and / or the spatial distribution of the two section types are preferably selected in the sense of mutually neutralizing the charges generated by the sections on the hair. With appropriate adaptation of the material, volume and spatial distribution, hair combed with the comb according to the invention shows practically no resulting electrostatic charge. In principle, however, it is also within the scope of the invention to specify a specific, desired electrostatic charge by selecting the individual materials, volume ratios and / or spatial distributions of the two section types.
Anhand der schematischen Darstellung eines Ausführungsbeispiels werden weitere Einzelheiten der Erfindung erläutert. Es zeigen :
- Fig. 1 einen Kamm in der Gesamtansicht; und
- Fig. 2 einen Querschnitt zur Längsrichtung des Kamms.
- Figure 1 shows a comb in the overall view. and
- Fig. 2 shows a cross section to the longitudinal direction of the comb.
Der Kamm nach Fig. 1 und 2 besteht aus Kammzinken 1 und Kammrücken 2. Beispielsweise kann ein Schichtaufbau des Kamms gemäß Fig. 2 vorgesehen werden, derart, daß der Kamm aus zwei alle Zinken 1 und den Rücken 2 umfassende Schichten 3 und 4 zusammengesetzt wird. Die beiden Schichten können mit Hilfe einer Klebstoffschicht 5 zu einem Gesamtinstrument verbunden werden.1 and 2 consists of comb teeth 1 and comb
Das Ausführungsbeispiel der Volumenverteilung der Einzelmaterialien des Kamms nach Fig. 2 ist zwar besonders günstig stellt aber nicht den allein möglichen Aufbau dar. Zum Erreichen des erstrebten Ziels können beispielsweise auch jeweils vollständige Zinken abwechselnd aus dem einen oder anderen Materialtyp hergestellt werden.The exemplary embodiment of the volume distribution of the individual materials of the comb according to FIG. 2 is particularly favorable, but does not represent the structure that is possible on its own. To achieve the desired goal, complete tines can, for example, also be produced alternately from one or the other material type.
Die Materialien der beiden Abschnittstypen zum Herstellen des Kamms werden aus der vorgenannten Spannungsreihe so ausgewählt, daß der hergestellte Kamm bei Anwendung eine bestimmte, in der Regel aber keine resultierende Aufladung der Haare ergibt. In einem besonders günstigen Ausführungsbeispiel besteht der eine Abschnitt aus Polyamid, insbesondere aus Nylon, und der andere Abschnitt aus Polyäthylen oder Acryl-Butadien-Styrol-Copolymer. Ein besonders geeignetes, erfindungsgemäß mit Nylon zu kombinierendes Polymer ist das von der BASF AG, Ludwigshafen, unter dem Markenzeichen Lupolen gelieferte Material.The materials of the two section types for producing the comb are selected from the aforementioned series of voltages in such a way that the comb produced results in a specific, but generally no resulting charge on the hair when used. In a particularly favorable embodiment, one section consists of polyamide, in particular of nylon, and the other section consists of polyethylene or acrylic-butadiene-styrene copolymer. A particularly suitable polymer to be combined with nylon according to the invention is the material supplied by BASF AG, Ludwigshafen, under the trademark Lupolen.
