Description
Technical field
The present invention relates to a kind of the make method of multilayer bristle material and the multilayer bristle and the application thereof made from this method.
Background technology
The present invention relates to bristle material, it for example is used to be fabricated to the bristle of cleaner between hairbrush that cleaning, polishing or brushing medium use, tooth or analog.The effect of the bristle plug material that bristle or are made up of many bristles and/or a plurality of bristle tuft depends on the selection of material on the one hand, depends on the structural design of bristle on the other hand, especially its surface.Mainly just work when cleaning or when inserting in gap, the cavity etc. in the end of bristle in this respect, and the conclusive working portion of bristle is made of the bristle bar, and the bristle bar is crooked and produce either large or small erasing to scraping or even the effect of filing when pressurization.Therefore, be the surface texture of bristle bar for the effect key of making every effort to obtain.
This understanding causes multiple bristle configurations.There is direct geometry on the surface of for example known (US 4373541) bristle.But the manufacture method of this bristle is extremely complicated.The bristle of known in addition two kinds of compositions (WO 97/25902, and US 3698405), it is formed by one or more monofilament with round their overcoat.Also known in addition multifilament is become a bristle (DE 1222888, DE19640853, JP 3289906) by mutual twisting, twisting etc.The manufacturing of this bristle material is fairly simple, but must monofilament be connected to each other by adhesive or other appropriate modes, so that obtain stable combination.Problem is the end design of this bristle, because they can not cavetto, yet is necessary to do like this in the application target of many bristles.
(DE 3717475, US3698405), wherein add on the monofilament core of carrying and help the layer that adheres to, fill out fiber then on the layer of this humidity for cleaner between last more known bristles and tooth.Fiber should be substantially perpendicular to the surface.Though this bristle produces novel effect and especially can be used for absorbing the medium of coating, however not these short fibers fixing very not firm on monofilament surface, so As time goes on they can become flexible and come off.Consequently not only cause reducing the effect of making every effort to reach, and the fiber that comes off is stayed on the processed surface badly.If this bristle is applied in and for example is applied in the health field in oral cavity and the tooth hygiene, the fiber that then comes off allows the people feel under the weather.
Become known for the bristle (JP 10286122A) of toothbrush in addition, they are made up of the polyamide monofilament core and the hoop silk that encloses that is added in around it, the latter or along the bus extension of core or helical coil on core.Silk can be made by polyamide equally.This silk should strengthen bristle, improve its reset force and increase the service life.This prior art do not illustrate helical coil around the fixed form of polyamide filament.The bristle (JP6321680A) that is used for cleaning roller at another kind is known, and round the multifilament core of being made up of the abrasion resistant particles of Fypro and fusion, coiling one deck or two-layer monofilament Fypro are followed the fiber by the adhesive fixing wound.In this design, the clear effect of the brush of bristle is subjected to the fixedly very big influence of adhesive of usefulness, because adhesive applies afterwards.Between the monofilament of compound core and coiling, form and be connected.Therefore the monofilament circle is by the coiling of enclosing the land, and slides with respect to fuse avoiding.
The bristle of known at last (DE 122888B) industrial rotating brush, reeling round the monofilament fuse, one or more layers strengthens the monofilament of usefulness.Adding in advance on this fuse or on this monofilament that adhesive is as the intermediate layer.The rapid making of this multistep is cumbersome.Whether careful the adhesiveness of monofilament on fuse depend on ground and by uniform bed thickness adhesive coating.Monofilament on the coiling only should strengthen and protect fuse, should only be provided by fuse and brush clear effect.That is to say, brush clear task and obviously bear by the bristle point.
Summary of the invention
The objective of the invention is a kind of method of making bristle material of suggestion, the bristle that adopts this material to make has the bristle bar effect that conforms to application target.In addition, the present invention also provides a kind of corresponding bristle.
For reaching this purpose, according to the present invention, a kind of method of making the multilayer bristle material is proposed, bristle is by the fuse of a decision bristles bend ability, the clear effect of decision brush is made up of outer and intermediate layer that continuous material constitutes, wherein fuse is by being crushed to and adding the intermediate layer of liquid phase to the viscous phase, under situation about continuous material partly being mounted in the intermediate layer, on the intermediate layer, add continuous material then, wherein, fuse and intermediate layer co-extruded, and after predetermined discharge distance, continuous material is applied on the intermediate layer having under the situation of pretightning force, and on above-mentioned discharge distance, the intermediate layer is converted to a state that solidifies more.
Different with the bristle of known three kinds of compositions, help the intermediate layer that adheres to and the core material co-extruded that can form by monofilament or multifilament, and the intermediate layer at first is converted to a kind of like this state, promptly be added in continuous material on the intermediate layer in this state and when applying owing to pretightning force arranged thereby be mounted in the intermediate layer to small part.
If the intermediate layer is adjusted softerly and the energy plastic deformation, then pretightning force is enough to embed continuous material in the intermediate layer and can not fix slippingly.
Replace this way, the intermediate layer also can be with the material manufacturing that can react after a kind of processing.Continuous material is placed on the dry also no longer flexible in case of necessity intermediate layer in this case.In settling the process of continuous material or after this, the intermediate layer reaction also then recovers its solid phase under the situation of continuous material build-in.
By reaction, the intermediate layer is softening, so slightly depression of the continuous material that is coupled with.Also can there be cementation in this intermediate layer, and it for example is made of a kind of adhesive of fusing, so continuous material is connected with fuse by bonding.But meanwhile guarantee all the time to be retained on the bristle bar fully or basically, and can not get loose by the skin that continuous material constitutes by the given structure of continuous material.
Also can add the intermediate layer of foamable material system in addition and add the continuous material post-foaming, thus continuous material to small part round the intermediate layer, and continuous material is mounted in the intermediate layer in this way.If the intermediate layer is made by the foam that therefore soft corresponding deformation under pressure also leaves continuous material, then can also deeper embed.
Must extend because be used for the monofilament of bristle, so that the bending rigidity that bristle is necessary so stipulate that in the another kind of scheme by the inventive method fuse jointly pushes with the intermediate layer and extends, just adds continuous material then.Fuse and intermediate layer and the continuous material that adds replenish once more and extend in case of necessity.
By another design code, after adding continuous material on the intermediate layer, add upper film, under the situation of the obvious moulding that causes owing to continuous material, film impels the profile smoothing.
Can stipulate in addition, after adding continuous material on the intermediate layer, bristle material be carried out post processing in the outside.Machining, dipping can be related to here, also coating media can be related to.Machining can comprise at least longitudinally cuts continuous material on the partial-length of bristle material, thereby fibre end forms effects such as corresponding cleaning, polishing freely.
Preferably apply a kind of textile material as continuous material, it can have smooth or coarse surface.The combination of a kind of plastic monofilament and the textile material on the outside is provided thus first, and it has enough adhesivenesses on the intermediate layer.Textile material can be rolled up or put.
If adopt the absorbability textile material, for example yarn of napping or analog then provide the possibility of varied health care and cleaning thus, also provide to apply liquid possibility to the fine powdered medium, and these media disengage in use again.
Continuous material also can be made by filament or by the plastic monofilament with abrasive characteristic.
The invention still further relates to the multilayer bristle, it is made up of outer and intermediate layer that helps to adhere to that continuous material constitutes a fuse that especially determines crooking ability, one the especially clear effect of decision brush.Be characterised in that by this bristle of the present invention, fuse and intermediate layer co-extruded, and reel or the continuous material that puts is partially submerged in the intermediate layer at least.
Preferably the intermediate layer is made by a kind of material softer than fuse, and fuse can be made of monofilament or multifilament.The material of the especially available a kind of caoutchouc elasticity in intermediate layer is made, and the pretightning force when it is only reeled by continuous material just can be embedded by continuous material.It is like this equally when the intermediate layer is made by expanded material.
Bristle by the present invention's design can be used for multiple application target, for example is used as the bristle plug material of brush or hairbrush.It individually also can be as the cleaner between tooth.At last, it can be applied to instrument by favourable mode, especially is applied to brush or hairbrush, and they are used for the liquid or pulverous medium of brushing blending in textile material.
