BRISTLE MATERIAL, MULTILAYER BRISTLE AND THE USE THEREOF
The invention relates to a method for the manufacture of multi-layer bristle material comprising a core which mainly determines the bending capacity of the bristle, a covering layer made from a continuous material and mainly determining the brushing action and an intermediate layer, in that the core is manufactured by extrusion, is then provided with the intermediate layer in a liquid to viscous phase and the continuous material is applied to and partially embedded in the intermediate layer.
The invention relates to bristle material such as is used for the manufacture of brushes for cleaning, polishing or applying media, for paint brushes, interdental cleaners, etc.. The action of a bristle or a bristle configuration comprising several bristles and/or bristle bundles is on the one hand dependent on the choice of material and on the other on the structure of the bristle and particularly its surface.
A part is played by the ends of the bristles essentially only during cleaning or penetrating gaps, cavities, etc., whereas the main action part of the bristle is formed by the bristle shank, which is bent round on pressure application and produces a wiping to scraping or even a roughening action.
Thus, decisive importance for the sought action is attached to the surface structure of the bristle shank.
This finding has led to numerous bristle constructions. Thus, it is known (US 4373541) to directly geometrically structure the surface of a bristle. However, the production processes for such bristles are extremely complicated. In addition, two-component bristles are known (WO 97/25902, US 3 698405), which comprise one or more monofilaments and a jacket enveloping the latter. It is also known to twist or otherwise combine several monofilaments to form a bristle (DE 1222888, DE 19640853, JP 3289906). However, although the production of such a bristle material is comparatively simple, the monofilaments must be joined together by means of adhesives or in some other suitable manner in order to obtain a stable union. The design of the ends of such bristles is problematical, because they cannot be rounded, which is necessary for many bristle uses.
Finally, bristles and interdental cleaners are known (DE 37 17 475, US 3 698 405), in which an adhesion promoting coating is applied to a bearing monofilament core and fibers are then flocked onto the moist coating. The fibers are to be essentially perpendicular to the surface. Although such bristles can lead to novel effects and can in particular be used for absorbing coating media, the short fibers do not have an adequate hold on the monofilament surface, so that over a period of time they loosen and drop out. This not only leads to a reduction of the sought action, but the dropped out fibers are extremely undesirable on the surface being treated. If such bristles are used in the hygienic sector, e.g. in oral and dental care, dropped out bristles lead to extremely unpleasant effects.
Bristles for tooth brushes have also been disclosed (JP 10 286 122A) having a nylon monofilament core with a stiffening wire introduced about its girth which either travels along an outer envelope of the core or which winds helically about the core. The wire can also be made from nylon. The wire should stiffen the bristle, improve its restoring forces and increase its lifetime. The reference is silent concerning the manner in which the wound nylon wire is anchored. Another bristle for brush rollers (JP 6 321 680A) has a core made from a multi-filament of nylon fibers with abrasive particle additives about which one or two layers of monofilament polyamide fibers are wound with the winding subsequently being secured using glue. In this bristle, the properties of the brush are substantially influenced by the anchoring glue, since it is introduced at the end of the process. There is no formation of a composite material comprising the multiple core and the wound monofilament. The monofilament is therefore wound in adjacent windings to prevent slippage relative to the core.
DE 1 222 888 B proposes a bristle for rotating technical bristles having a monofilament. core wound with a stiffening monofilament once or a plurality of times. Glue is previously applied to the monofilament in the form of an intermediate layer. The multi-step production is difficult. Bonding of the monofilament to the core requires the glue to be carefully applied in an even layer of constant thickness. The wound monofilament is only intended to stiffen and protect the core, whereas the brushing effect should be solely produced by the core. The brushing action is therefore clearly produced by the tips of the bristles.
The problem of the invention is to propose a method for the manufacture of bristle material from which it is possible to produce bristles with a bristle shank action matched to the intended use. The invention also aims at providing a corresponding bristle.
On the basis of the method according to the preamble of claim 1, this problem is solved in that the core and the intermediate layer are co-extruded and following removal to a predetermined withdrawal length at which the intermediate layer has transformed into a sufficiently solid state, the continuous material is applied to the intermediate layer with pre-tensioning.
Unlike in the case of the known, three-component bristles, the adhesion promoting intermediate layer is co-extruded together with the core material, which can be formed from monofilaments or multi-filaments, with the intermediate layer being initially changed into a state in which the continuous material can be applied to the intermediate layer to at least partially embed in the intermediate layer in consequence of the pre-tensioning.
If the intermediate layer has a corresponding soft setting and is plastically deformable, the pretension is sufficient in order to incorporate and immovably hold the continuous material in the intermediate layer.
Instead the intermediate layer can be made from a material which can be reactivated after processing. In this case the continuous material is applied to the dry and optionally also no longer deformable intermediate layer. During or after the application of the continuous material the intermediate layer is reactivated and subsequently returned to its solid phase accompanied by the embedding of the continuous material.
As a result of the reactivation, the intermediate layer becomes soft, so that the continuous material applied sinks in to a certain extent. The intermediate layer can also have an adhesive action and can e.g. comprise a hot melt adhesive, so that the continuous material is joined to the core by adhesion. However, it is always ensured that the structure given by the continuous material to the bristle shank is completely or preponderantly maintained and that there is no detachment of the covering layer formed from the continuous material.
It is also possible to apply an intermediate layer of a foamable material and to foam the intermediate layer following application of the continuous material, so that the intermediate layer at least partly surrounds the continuous material and in this way the latter is embedded into the intermediate layer. It is also possible to have a deeper embedding if the intermediate layer comprises a soft or flexible foam, which correspondingly gives way under pressure and consequently exposes the continuous material.
As monofilaments for bristles have to be stretched in order to give the bristle the necessary flexural strength, in a further variant of the method according to the invention the core together with the intermediate layer are co-extruded and stretched and only subsequently is the continuous material applied. Optionally the core with the intermediate layer and the applied continuous material can then be further stretched.
According to another embodiment, a film is applied following the application of the continuous material to the intermediate layer to smooth a given, prominent profiling caused by the endless material.
It is also possible following the application of the continuous material to the intermediate layer to externally subsequently treat the bristle material. This can be a mechanical working, a dipping or the application of coating media. A mechanical working can comprise the longitudinal cutting open of the continuous material, at least over partial lengths of the bristle material, so that free fiber ends with a corresponding cleaning, polishing or similar action are obtained.
A textile material is preferably used as the continuous material and can have a smooth or a roughened surface. Thus, for the first time a combination of plastic monofilaments with a textile material on the outside is provided, which has an adequate adhesion to the intermediate layer. The textile material can be wound or looped on.
Use of an absorbing textile material, e.g. a roughened yarn or the like, leads to numerous care and cleaning possibilities, as well as permitting introduction of liquid or finely powdered media, which are released during use.
The continuous material can also comprise an ultra-fine metal wire or a plastic monofilament with abrasive characteristics.
The invention also relates to a multi-layer bristle, which comprises a core mainly determining the bending capacity, a covering layer, made from a continuous material and mainly determining the brushing action and with an intermediate layer for promoting adhesion. According to the invention, such a bristle is characterized in that the core and the covering material are co-extruded and the continuous material wound or looped onto the intermediate layer is at least partly incorporated or embedded into the intermediate layer.
Preferably the intermediate layer is made from a softer material than the core, which can comprise a monofilament or multi-filament. The intermediate layer can in particular comprise a rubber-like material, which permits an embedding of the continuous material solely through the pretension thereof on winding. The same applies for an intermediate layer of a foamed material.
The bristle constructed according to the invention can be used for numerous different purposes, e.g. for the bristle configuration of brushes or paint brushes. Alone it can serve as an interdental cleaner. It can finally be advantageously used for implements, particularly brushes or paint brushes used for applying liquid or pulverulent media, which are then embedded in the textile material.
The invention is described in greater detail hereinafter relative to embodiments and with reference to the attached drawings, wherein show:
Fig. 1 a perspective view of a portion of the bristle material in a first embodiment.
Fig. 2 a cross-section through the bristle material according to fig. 1.
Fig. 3 a longitudinal view of the bristle material in another embodiment.
Fig. 4 a cross-section through the bristle material in a further embodiment.
In the embodiment according to Fig. 1 the bristle material 1 has a core 2 essentially determining the bendability of the finished bristle and formed from one or more plastic monofilaments. Onto the core 2 is applied an intermediate layer 3, which is preferably made from a softer material.
Onto the intermediate layer is applied a continuous material 4, e.g. a natural or synthetic textile material, which at least on its side facing the intermediate layer is incorporated or embedded in the latter, so that the continuous material 4 is secured to the intermediate layer 3.
It is naturally also possible to wind on several continuous fibers, in parallel or crosswise.
In the embodiment according to Fig. 3 the bristle material 1 once again has a core and an intermediate layer onto which the continuous material 4 is not only wound, but simultaneously also looped. As in the case of the bristle material according to Figs. 1 and 2, the continuous material is incorporated into the intermediate layer by appropriate pre-tension. Instead of or in addition thereto the intermediate layer can be made from a material which undergoes a change of state through an activation process, e.g. through the application of heat to effect or assist the embedding of the continuous material.

The core can have any arbitrary cross-sectional shape adapted to the intended use. An embodiment is shown in Fig. 4. The bristle material 1 has a roughly rhombic core 5 to which the intermediate layer 6 is applied and simultaneously fills the convex spaces of the core 5. The continuous material is then e.g. wound or looped onto said intermediate layer. As a result of the profiling of the core 5, a bristle of the bristle material according to Fig. 4 has preferred bending directions. As a result of the convex areas filled with the intermediate layer the wear behavior can be influenced. The bristle shank action sought through the continuous material occurs to different extents over the bristle circumference.
This finding has led to numerous bristle constructions. Thus, it is known (US 4373541) to directly geometrically structure the surface of a bristle. However, the production processes for such bristles are extremely complicated.
