Definitions
- the present invention relates to a new fiber having particularly advantageous characteristics for producing duplicators comprising a plurality of bristles, such as, for example, paintbrushes or brushes.
- the invention finds a particularly advantageous application in the field of the application of cosmetic products.
- the subject of the present invention is therefore a monofilament plastic fiber having any cross section, the circular envelope of which has a diameter of between 0.03 and 0.40 mm, characterized in that the plastic material constituting the fiber contains from 0.2 to 15% by weight of at least one agent improving the sliding characteristic of the fiber and reducing its wettability with water and / or solvents.
- the slip agent is chosen from the group formed by teflon, boron nitride, molybdenum bi-sulfide, graphites, fullerene and talc.
- the fiber section can be any, in particular flat, circular, polygonal, cruciform, annular or U-shaped; fiber can also include at least one capillary channel of straight or wavy linear shape and the section of which may not be symmetrical.
- the plastic material constituting the fiber is advantageously chosen from the group formed by polyamides, polyesters, polyether-block amides and polytetrafluoroethylene. When the fiber consists of a polyamide, polyamides 6, 6-6, 6-10, 6-12 or 11 can in particular be used. The end of the fiber can be treated, for example by grinding, or hot .
- the present invention also relates to a liquid product applicator comprising a plurality of bristles mechanically connected to the same element, the operation of which allows the distribution of the product in a layer on a support, characterized in that at least part of the bristles of the applicator is constituted by sections of fibers as defined above.
- the applicator according to the invention constitutes a brush, the bristles of which are substantially parallel and carried by a handle: this is the case, in particular, for a nail varnish applicator.
- the applicator according to the invention constitutes a hair brush, the bristles of which are implanted in tufts on a support such as a plate.
- the applicator according to the invention constitutes a brush, the bristles of which are clamped by their central zone in a core, the bristles having approximately a radial direction relative to the core;
- the core may consist of a twisted metal wire of 0.3 to 0.9 mm in diameter, the bristles of the brush being blocked in the twists of the core: this is the case, in particular , for a mascara brush.
- the bristles is made up of fibers according to the invention.
- the fibers having improved sliding characteristics can either be statistically mixed with fibers of conventional type, of the same section as the section of fibers with improved sliding characteristics or of different section, or else, on the contrary, located in certain areas of the applicator.
- the central part of the brush can be constituted by fibers of the conventional type while the peripheral part consists of fibers with high sliding characteristic.
- the use of the fibers according to the invention for the production of cosmetic applicators has very significant advantages. Firstly, the product is better distributed over the bristles of the applicator, which makes it possible to use bristles of larger diameter, on the one hand, and to increase the speed of application of the product to the support, on the other hand. In addition, the product has a greater tendency to remain on the support than on the bristles of the applicator, which makes it possible to achieve a greater distribution in layers.
- the mascara tanks have diaphragms serving to wipe the brush each time it is extracted from the tank; it was found that with the fibers according to the invention, the wringing distributed the product perfectly over the bristles of the brush and that, in addition, the brush was less fouled and therefore less contaminated, since the product slides along hairs with each application and is renewed regularly instead of forming residues along the hairs. It has also been found that the application of the mascara to the eyelashes is carried out more gently and gives rise to a more regular film.
- a spiral brush intended for making up the eyelashes is produced using a liquid mascara consisting of an aqueous composition having a viscosity of 90 poises (9 Pa.s).
- the bristles of the brush consist of polyamide "nylon 6-10" fibers comprising 8% by weight of boron nitride (BN) 6.
- the brush consists of a core of twisted wire having a diameter of 0.7 mm, the twists of the core retaining by their central zone approximately 500 bristles which are uniformly distributed in 17 turns corresponding to the twists of the core .
- the brush has a cylindrical shape of 26 mm in length and 6.5 mm in diameter.
- the bristles of the brush have a diameter of 0.15 mm and their section is a solid circular section.
- Polyester fibers are produced containing 10% by weight of teflon. These fibers have a cruciform cross section contained in a circular envelope having a diameter of 0.15 mm.
- a brush is made up of parallel bristles having a length of 17 mm. This brush has 150 bristles.
- the brush is used with a nail varnish having a viscosity of 4 poises (0.4 Pa.s). It can be seen that the layer of nail varnish obtained on a nail is perfectly distributed and thicker than with the brushes of the prior art.
- EXAMPLE 3 Polyether-block amide fibers are produced containing 6% by weight of molybdenum disulphide. These fibers have a circular cross section and have a longitudinal capillary groove.
- the diameter of the cross section is approximately 0.3 mm; the capillary groove has, on the periphery of the fiber, a width of approximately 0.06 mm and this groove has a depth of approximately 0.06 mm.
- the fibers defined above are used to make the bristles of a hair brush. Each pile has a length of 35 mm above the plate, which constitutes the support.
- the bristles are implanted in tufts of 10 bristles, the holding in position of the bristles being carried out, in known manner, by bending U-shaped sections of fibers of double length and by pushing the tufts into a housing by means of a retainer inserted at strength.
- Such a brush is used to spread over the hair of a subject a treatment product having a viscosity of 3 poises (0.3 Pa.s) seconds. It is noted that the coating of the hair is carried out more regularly than with a brush of the technical state and that the brushing of the hair is more pleasant for the subject treated.
