- polyphenylene ketones examples include poly-p-phenylene ketones, for example homopolymers or copolymers which contain repeating structural units -para-C 6 H 4 -CO-.
- polyphenylene ether ketones examples include poly-p-phenylene ether ketones, for example, copolymers containing repeating structural units -para-CgH 4 -CO- and recurring structural units -para-C 6 H 4 -O-.
- liquid-crystalline polymers examples include liquid-crystalline aromatic polyesters, for example homopolymers or copolymers, which contain repeating structural units derived from para-hydroxybenzoic acid.
- a plastic filament bristle the polymer matrix of which comprises at least one further thermoplastic polymer, in addition to the thermoplastic aliphatic polyketone which is composed of carbon monoxide and alkyl units, such as one or more polymers of the above type in that the polymer matrix of the plastic filament at least partially consists of a polymer blend of the at least one thermoplastic polyketone and the at least one further thermoplastic polymer is formed.
- thermoplastic aliphatic polyketone according to step (a) is up to about 30% by mass, in particular up to about
- thermoplastic polymer in particular from the group of polyolefins, the polyester, the polyamides, the polyoxymethylene, the polyurethanes, the polyphenylene sulfides, the polyphenylene sulfone, the Polyethersulfone, the polyphenylene ether, the polyphenylene ketones, the polyphenylene ether ketones, the polyetherimides, the Polyetheretherketo- ne, the thermoplastic elastomers, preferably in the form of thermoplastic polyurethanes, polyesters and / or polyamides, and the liquid crystalline polymers added.
- the polymer matrix of which, in addition to the thermoplastic aliphatic polyketone, which is composed of carbon monoxide and alkyl units, contains at least one further thermoplastic polymer, such as one or more polymers of the abovementioned type, may alternatively or additionally that the plastic filament has a cross-section in which the at least one thermoplastic polyketone and the at least one further thermoplastic polymer are spatially separated but arranged together, in particular in a side-by-side and / or or a core-shell structure. From a procedural point of view, it can therefore be provided in this context that the method comprises the following additional steps:
- thermoplastic polymer in particular from the group of polyolefins, polyesters, polyamides, polyoxymethylenes, polyurethanes, polyphenylene sulfides, polyphenylene sulfones, polyethersulfones, polyphenylene ethers, polyphenylene ketones, polyphenylene ether ketones, polyetherimides, polyetheretherketones containing thermoplastic elastomers, in particular in the form of thermoplastic polyurethanes, polyesters and / or polyamides, and the liquid-crystalline polymers; and
- step (b2) extruding both the spinning mass according to step (a) and the other spinning mass according to step (a2) in an extruder through at least one nozzle plate with one or more spinning capillaries, so that each spinning capillary of both the spinning mass according to step
- step (A) and by the further dope according to step (a2) is flowed through.
- thermoplastic polymers for producing filaments Such coextrusion of various thermoplastic polymers for producing filaments is known as such from the prior art.
- cross-sectional shape of the plastic filaments according to the invention does not necessarily have to be (circular) round, but to be arbitrary.
- these may be regular or irregular cross-sections, point- or axis-symmetrical cross-sections, for example round, oval or n-cornered cross-sections, where n is greater than or equal to 3, to tri or multilobal cross sections and the like.
- a corrugation with any amplitude and / or wavelength can be pressed in, or it can be applied to the outer surface of the plastic filament, e.g. another embossing are applied, which is advantageously carried out before the filaments are cut to length according to step (f).
- the bristle of the invention may also be taped mechanically and / or chemically. Further features and advantages of the invention will become apparent from the following description of an embodiment with reference to the drawing.
- the single FIGURE shows a schematic detail view of an embodiment of a toothbrush with thin bristles formed from sections of a plastic filament based on thermoplastic, aliphatic polyketones.
- the graphically reproduced toothbrush comprises a bristle carrier 1 and a handle 2 (shown broken off), which in the present embodiment is a formed lumpy and are made for example of one or more conventional, especially thermoplastic, plastics.
- a plurality of bristles 3 is fixed, which may be fixed in the bristle carrier 1 by means of encapsulation, for example, and in the present case are arranged in a plurality of bristle bundles 4 arranged in rows and columns, for example in matrix-like fashion.
- the bristles 3 each consist of a section of a thermoplastic filament based on thermoplastic, aliphatic polyketones, as described in detail above.
- the diameter of the bristles is advantageously less than about 0.08 mm, for example in the range between about 0.02 mm and about 0.05 mm, so that they can easily penetrate into interdental spaces during the intended use of the toothbrush and a very high number
- bristles of between about 5,000 and about 7,000, such as about 6,000 can accommodate bristle carriers to provide a very efficient cleaning action.
