Definitions
- the invention relates to a thermoplastic monofilament for bristles that are exposed to increased moisture when in use.
- Brushing, polishing, when applying media or the like result from the conditions immediately prevailing during use or at the place of use.
- the auxiliary media used during use such as cleaning agents, cleaning agents, cosmetics, water or the like, should be mentioned in particular.
- the ambient conditions at the place of use include, in particular, increased air humidity which, in interaction with moist auxiliary media, helps to prevent the moist auxiliary media from drying.
- Bristles must therefore have a property profile that meets these very different requirements. This is exemplified by a toothbrush, in which the different requirements become particularly clear because the bristles initially have an extremely small diameter, which is approximately between 0.05 and 0.4 mm.
- the bristles are arranged at a short distance from one another and even packed tightly in bundles.
- bristles for toothbrushes have to show a good high bending behavior in order to be able to dodge in the purely elastic area and on the other hand to be able to return to the starting position without deformation (straightening ability).
- the bristles Due to the multitude of forms of movement and the pressure depending on the user when brushing the teeth, the bristles must have good flexural fatigue strength and fatigue strength, taking into account an appropriate service life.
- the plastic must be such that the bristle can be processed in mechanical or thermal manufacturing processes, including in particular the attachment of the bristles to the bristle carrier.
- the bristles must be rounded at the end of use in order to produce a gentle, yet sufficient brushing effect on the tooth surfaces and in the interdental spaces, on the one hand, and on the other hand without causing the tooth enamel to become too hard
- Coextruded filaments are known in textile technology (EP 0 763 611 A1), which consist of a polyester core and a polyamide sheath, but the focus here is on other property profiles than is the case with bristles.
- coextruded monofilaments for toothbrushes are known (WO 97/14830), which consist, among other things, of a polyamide sheath and a polyester core only high-quality polyamides are used in the jacket.
- the core consists of a copolyether ester, which is, however, an elastomer and therefore does not meet the requirements for a bristle for toothbrushes.
- the core and jacket consist of differently treated polyvinyl chlorides.
- the object of the invention is achieved on a thermoplastic monofilament forming the starting material for bristles in that the monofilament has a polymer mixture of at least one polyamide (PA) and at least one thermoplastic polyester (PE).
- PA polyamide
- PE thermoplastic polyester
- the specific mixing ratio (PA / PE) is selected on the one hand in accordance with the technical and functional properties relevant for the use of the bristle and on the other hand with the environmental conditions relevant for the function of the bristle at the place of use.
- the proportions of the polymers in the blend for extrusion of thermoplastic monofilament can be applied to the Anfor ⁇ alteration profile of the bristle optimally adjusted.
- the bending behavior and the bend recovery in adjustment can be sung to bristle diameter and length as well as to the specific type of use of the bristle (toothbrushes, massage brushes, hand ⁇ brushes, cosmetic brushes, paints, etc.) to adjust.
- It can also take into account the physical and chemical conditions prevailing at the place of use due to the media used there (dentifrices, cleaning agents, water etc.) and adapt to the prevailing environmental conditions (dry or humid atmosphere, moisture retention in the bristles, etc.).
- the thermoplastic polyester is preferably a polyalkylene terephthalate (PAT), in particular polyethylene terephthalate (PET) or polybutylene terephthalate (PBT) or a mixture thereof.
- PAT polyalkylene terephthalate
- PET polyethylene terephthalate
- PBT polybutylene terephthalate
- thermoplastic polyesters are not only interesting - their technological properties make them particularly suitable for bristles, they are also much cheaper than the high-quality polyamides previously used for toothbrush bristles, such as PA 6.12.
- a high proportion of PAT also gives the opportunity to replace high-quality PA, at least in part, with low-value and inexpensive PA such as PA 6.
- the coextrudate can have the two layers in concentric form, ie in the form of a core and a jacket. Instead, the coextrudate can also have a plurality of monofilaments which are embedded in a second layer which determines the outer cross section of the monofilament. Furthermore, the coextrudate can consist of a core that defines only a part of the circumference, while the second layer forms segments that complete the circumference, for example have a substantially rectangular cross section, which is predominantly from one layer and only in the corners from the other layer is formed.
- the second layer and the second layer may consist nem single polyamide or mixture of polyamides from egg ⁇ , conversely, of a thermoplastic polyester or a mixture of such polyesters can be formed.
- the coextrudate consists of a core and a jacket
- the core consists of a PAT or a mixture of polyalkylene esters
- the jacket is formed from a polyamide or a polyamide mixture.
- the core essentially determines the bending behavior and the ability to straighten up, while the jacket is essentially responsible for the brushing effect, for the distribution of application media or cleaning media.
- Such a bristle has an increased water absorption in the jacket, but this has no or only an insignificant effect on the strength property, since this is largely determined by the core with its considerably reduced moisture absorption.
- the core can also consist only of a thermoplastic polyester or a polyester mixture, since it is not directly involved in the brushing effect, while the jacket consists of the polymer mixture according to the invention.
- the polymer mixture according to the invention can be present both in the core and in the jacket, the mixing ratio in favor of the PE or PAT component being increased in the core, in the jacket in favor of the PA component.
- the excellent strength properties of the polymer mixture according to the invention furthermore make it possible to provide a shell made of any polymer, in particular a PA or a PA mixture, in the case of a core consisting of this mixture.
- a shell made of any polymer in particular a PA or a PA mixture
- polyamides for example, can be colored particularly well.
- This combination of materials also enables the jacket to be made extremely thin.
- the bristle diameter varies from 5.0 mm for coarse brushes, such as street brushes, to 0.1 mm for toothbrushes, cosmetic brushes etc.
- the sheath can have a thickness of 0. 01 to 0.5mm.
- the thickness of the Coat lie in the range between 10 and 50 ⁇ .
- the polymer mixture according to the invention with its stability-determining properties also gives the possibility of also providing three-layer coextrudates, for example by the core consisting of a PAT or a PAT mixture, an intermediate layer made of the polymer mixture according to the invention and an outer layer made of an elastomer or an elastomer. Blend exists.
- a copolyether ester is particularly recommended because of its affinity for the polyester portion of the middle layer.
- the outer wear layer fulfills optimal requirements for fulfilling the requirement profile when brushing, cleaning, massaging or applying media.
- the core can also be designed as a hollow core in order to receive media and deliver it to the free end of the bristle.
- the sheath consists of the polymer mixture according to the invention or of PA or a PA mixture, a bristle consisting of a core and a sheath results in better machining of the bristle ends, in particular a perfect rounding enables without edge formation.
