Definitions

  • the invention relates to a plastic hair comb with comb teeth and comb back.
  • the hair and comb 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • hair combed with the comb according to the invention shows practically no resulting electrostatic charge.
  • a layer structure of the comb according to FIG. 2 can be provided such that the comb is composed of two layers 3 and 4 comprising all teeth 1 and the back 2 .
  • the two layers can be connected with the aid of an adhesive layer 5 to form an overall instrument.
  • 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.
  • complete tines can, for example, also be produced alternately from one or the other material type.
  • 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.
