Definitions
- the invention relates to a method for producing multilayer bristle material, consisting of a core which primarily determines the bendability of the bristle, a coating which primarily determines the brushing action and an intermediate layer, in that the core is produced by extrusion and with the intermediate layer from a liquid to viscous phase and then thereon with the covering.
- the invention relates to bost material, such as for the manufacture of brushes for cleaning, polishing, or for applying media, for brushes, interdental cleaners or the like. is used.
- the effect of a bristle or of a multi bristles and / or bristle bundles bristle depends both on the choice of material, on the other hand, the structural design of the bristle and the ⁇ particular of their surface.
- the ends of the bristles play a role only during cleaning or when penetrating into cracks, cavities, etc. the majority of the effective part of the bristle is formed by the bristle shaft, which turns over when pressure is applied and produces a more or less wiping to scraping or even roughening effect.
- the surface structure of the bristle shaft is therefore crucial for the desired effect.
- bristle designs It is known (US 4,373,541) to structure the surface of a bristle directly geometrically. The manufacturing processes for such bristles are extremely complex. Furthermore, two-component bristles are known (WO 97/25902, US 3,698,405), which consist of one or more monofilaments and a sheath enveloping them. It is also known to twist, twist, or the like to form a bristle or a plurality of monofilaments (DE 1 222 888, DE 196 40 853, JP 32 89 906).
- bristles and interdental cleaners are known (DE 37 17 475, US 3,698,405), in which an adhesion-promoting layer is applied to a supporting monofilament core and fibers are then flocked onto the moist layer.
- the fibers should be essentially perpendicular to the surface.
- Such bristles could produce novel effects and, in particular, could also be used to absorb application agents, but the short fibers have too little hold on the monofilament surface, so that they loosen and fail over time. This not only leads to a reduction in the desired effect, but the precipitated fibers on the surface to be treated are highly undesirable. If such bristles are used in the hygiene sector, for example in oral and dental care, unusual fibers lead to marked inconveniences.
- the invention is based on the object of proposing a method for producing bristle material, from which bristles can be produced with the effect of the bristle shaft that is tailored to the intended use. Furthermore, a corresponding bristle is to be created with the invention.
- this object is achieved in that the intermediate layer is brought into an approximately dry state and then the covering made of a continuous material is applied to the intermediate layer by incorporating it.
- the adhesion-promoting intermediate layer is first brought into a dry state after being applied to the core material, which can consist of monofilaments or multifilaments, and then the covering made of an endless material is applied to the intermediate layer, the continuous material being necessary the application or thereafter is at least partially embedded in the intermediate layer.
- the storage can take place, for example, in that the continuous material is applied to the intermediate layer under prestress. If the intermediate layer is made soft and plastically deformable, the prestress is sufficient to store the continuous material in the intermediate layer and to keep it immovable. Instead, it can be provided that the intermediate layer consists of a material that can be reactivated after processing. In this case, the continuous material is applied to the dry intermediate layer, which may also no longer be deformable. During or after the application of the continuous material, the intermediate layer is reactivated and then returned to its solid phase by incorporating the continuous material.
- the reactivation softens the intermediate layer, so that the continuous material applied sinks somewhat.
- the intermediate layer can also have an adhesive effect, for example consist of a hot melt adhesive, so that the continuous material is bonded to the core.
- an adhesive effect for example consist of a hot melt adhesive, so that the continuous material is bonded to the core.
- an intermediate layer made of a foamable material and to foam the intermediate layer after the application of the continuous material, so that the intermediate layer at least partially surrounds the continuous material and in this way the continuous material is embedded in the intermediate layer.
- a deeper embedding can also be provided if the intermediate layer consists of a soft foam that yields accordingly under pressure and thereby exposes the continuous material.
- the core and the intermediate layer are preferably co-extruded and, after a predetermined withdrawal distance, in which the intermediate layer has changed into a sufficiently solid, no longer lubricating state, the continuous material is applied to the intermediate layer.
- the core is co-extruded and stretched together with the intermediate layer and only then is the endless material applied. If necessary, the core with the intermediate layer and the applied continuous material can then be stretched again.
- a film is applied to the intermediate layer which, given a strong profile, causes the profile to be smoothed by the continuous material.
- the bristle material is post-treated on the outside. This can be mechanical processing, dipping or the application of application media.
- Processing can consist in that the continuous material is cut open at least over part of the length of the bristle material, so that free fiber ends with a corresponding cleaning, polishing effect or the like are produced.
- a textile material which can have a smooth or roughened surface is preferably applied as the continuous material.
- the textile material can be wound up or linked up.
- the continuous material can also be made of a metallic
- Very fine wire or made of a plastic monofilament with abrasive properties Very fine wire or made of a plastic monofilament with abrasive properties.
- the invention further relates to a multi-layer bristle which primarily determines the bending capacity
- Kern a covering which primarily determines the brushing effect and an intermediate layer for promoting adhesion.
- a bristle is characterized according to the invention in that the covering consists of an endless material wound or linked onto the intermediate layer and the endless material is at least partially embedded in the intermediate layer.
- the intermediate layer preferably consists of a softer material than the core, which can consist of a monofilament or multifilament.
- the intermediate layer can in particular consist of a rubber-elastic material which enables the continuous material to be stored solely by prestressing it during winding. The same applies to an intermediate layer made of a foamed material.
- the invention designed according to the bristle can be used for sauti ⁇ ge applications, for example for the bristle configuration of brushes or bristles. It can also serve as an interdental cleaner. Finally, it can be advantageously to devices, particularly brushes or brush insert that serve for the application of liquid or pulverulent media, which are then incorporated into the textile ⁇ material.
- the invention is described below with reference to exemplary embodiments which are shown in the drawing. The drawing shows:
- Figure 1 is a perspective view of a portion of the bristle material in a first embodiment
- FIG. 2 shows a cross section of the bristle material according to FIG. 1;
- Figure 3 is a longitudinal view of the bristle material in another embodiment
- Figure 4 shows a cross section of a bristle material in a further embodiment.
- the bristle material 1 has a core 2 made of a single or a plurality of plastic monofilaments which essentially determines the bending ability of the finished bristle.
- An intermediate layer 3 is applied to the core 2, which preferably consists of a softer material.
- several continuous fibers can also be wound up in parallel or crosswise.
- the bristle material 1 in turn has a core and an intermediate layer, onto which the continuous material 4 is not only wound, but also linked at the same time.
- the continuous material can be embedded in the intermediate layer by appropriate pretensioning.
- the intermediate layer can also consist of a material which undergoes a change in state through an activation process, for example through the action of heat, as a result of which the storage of the continuous material takes place or is supported.
- the core can have any cross-sectional shape adapted to the application.
- An embodiment is shown in Figure 4.
- the bristle material 1 has an approximately rhombic core 5, on which the intermediate layer 6 is applied, which at the same time fills the covex spaces of the core 5.
- the continuous material is then applied to this intermediate layer, e.g. wound up or chained up.
- a bristle made of the bristle material. 4 has 5 preferred bending directions due to the profiling of the core.
- the wear behavior can be influenced by the convex areas filled with the intermediate layer.
- the effect of the bristle shaft on the circumference of the bristle, which is sought by the continuous material, is brought to bear differently.
