Description

This invention is generally referred to the field of hair or similar applications to solve, for example, baldness problems and is specifically based on an adhesive for the application of hair or similar and on the related manufacturing process.
In the beauty field there are several systems of hair application such as wigs or through the sticking to the skin or to the scalp of a sheet shaped base having hair projecting from a face thereof.
The base can be of various nature: it can be made for example of tissue or plastic. To fix this base to the skin or to the scalp, it is necessary to use an adhesive that can have different shapes but that, anyway, since it is directly in touch with the skin, should not cause allergy, be transpiring and has to allow hair growth.
This kind of sticker is for example disclosed in FR 2,295,708 and a related manufacturing process is disclosed in DE 3126605.
Basically the adhesive can be provided in a quantity to be directly spread on the skin and/or on the inner part of the base or as bi-adhesive tape.
The presence of the base and the adhesive cannot often be so comfortable both for the weight on the skin and because it, the whole support usually covering a wide portion of skin and being stuck at several points, can cause itch or other troubles.
Another problem related to these applications is the care and labour to manufacture these bases on which there are uniformly inserted hairs.
In fact, to insert each hair to the base it is necessary to use sewing techniques, very demanding in terms of time, or glues not leading to good results in view of the risk to stick hair.
The technical problem at the root of the present invention is to provide a sticker for hair application that exceeds all the drawbacks mentioned with reference to the prior art.
The problem is solved by a sticker for the application of hair comprising an adhesive laminar support made of adhesive material, antiallergenic and transpirable, which comprises a first side wherein a plurality of hairs has been run into and a second side apt to be directly stuck to the skin and a support plane attached to said second side.
According to a preferred embodiment, the support plane is a removable film adhered to the second side to be removed before application, for example a silicone paper as the one used to protect self-sticking labels.
The main advantage of the sticker according to the present invention is that hair directly sticks to the skin without the above-mentioned base.
The present invention is also referred to a manufacturing process for the above defined sticker, comprising the steps of:
  • providing of an adhesive laminar support having a first and a second side, anti allergenic and transpirable, made of a layer of an adhesive material, on a support plane;
  • providing a quantity of hairs in proximity of this laminar support, each hair having an end apt to be run into said first side of said laminar support;
  • generating an electrostatic field at the laminar support so as to position said ends against the laminar support, causing them to run into the laminar support at the first side thereof, said second side of said laminar support being apt to be directly stuck to the skin.
The advantage of the manufacturing process according to the invention is the elimination of the manual application of hair on a support.
The present invention is hereinafter described according to some preferred embodiments thereof, provided for an exemplary and non limiting purpose with reference to the following examples and to the annexed drawings wherein:
  • figure 1A is a schematic and partially sectioned view of a flocking apparatus used in the process according to the invention;

  • figure 8A is a perspective view of a sticker according to the invention;
  • figure 8B is a section view of a sticker; and
  • figures 9A and 9B show two steps of sticker application.
In order to better explain some different manufacturing modes of the sticker according to the invention, some different processes will be described, the processes also being related to the same innovative concept.
With reference to figures 1A and 1B, in a first embodiment of a manufacturing process, a laminar support 1 made of adhesive material is provided on a support plane which is made in particular of a removable film 2, for example obtained in silicone-based paper of the kind used to protect self-sticking labels or in an equivalent material.
The adhesive material doesn't cause allergy and is transpirable.
The laminar support 1 and the removable film 2 are then treated according to a process of flocking called as velveting process, carried out with a flocking apparatus 3 which is schematically depicted in figures 1 and 2.
The film 2 is put on a first electrostatic plate 4 to which can be given, according to techniques known in the art and not disclosed herein, an electric charge, in particular a negative charge.
Above the plate 4 there is a closed space surrounded by a case 5 wherein a quantity of hairs 6 is let in, preferably but not exclusively natural hairs 6, having lengths necessarily non fixed but not too different than an average length from a few millimetres to a few centimetres.
Together with the hairs, an amount of soft flocking fibres is put in this space, as those usually employed for the production of chamois-tissues and velvet.
Hence, the hairs have two ends and one of these ends will be run into the adhesive laminar support under process.
The hairs are kept on excitation and suspension for example through an air flow. The case 5 has a further and second electrostatic plate 7 that, together with the previous mentioned one, generates an electrostatic field at the laminar support 1, thereby positioning said hair ends against the laminar support 1 and causing them to run into the laminar support 1.
According to the flocking process, said hairs are electrostatically charged and thrown down the laminar support 1. The electrostatic field and the charge of the hairs allow them to be on a vertical position so that one end thereof is run into the laminar support 1.
The same process acts on the flocking fibres filling all the spaces empty from hairs, the latter being larger. In this way, the so treated surface of the laminar support 1 assumes a soft compactness.
At the end of this step of running into, the hairs can be combed and carded (fig. 2) in order to confer to the hairs a fixed orientation and to eliminate all the excessive and non perfectly inserted hairs.
A further preferred embodiment refers to a calendering, preferably a hot-calendering, to confer to the hairs a modelled orientation, partings and so on.
At the end of this step, the sticker 10 is substantially ready to be used. The so treated laminar support 1 shows a first side 11, through which the hairs have been ran into, and a second side 13 that can be stuck onto the skin.
The laminar support 1 and the removable film 2 can be a rectangular sheet or a roll. In this case, the above-mentioned apparatus may work continuously according to techniques well known to the man skilled in the art.
When the hairs are satisfactorily stuck to the laminar support 1, it is possible to obtain stickers from the laminar support 1 and from the removable film 2, suitable to be applied to the skin.
These stickers (figures 9A and 9B) will preferably be small sized stickers to prevent waves during adhesion. They can have every shape through cutting or punching of the laminar support and the removable film.
They can have striped, arched, semicircle, circle, oval and elliptic shapes. They can be simply and directly stuck to skin, by simply taking off the removable film and adhering the opened side of the laminar support to the skin.
All the shapes can be pre-formed but also they can be formed at the moment, cutting the adhesive sheet according the invention following a preferred shape (figure 7).
Advantageously, the laminar support 1 has a small thickness, for example from 0,02 mm to 1,00 mm but preferably between 0,05 mm and 0,50 mm. The application techniques for applying the adhesive material to the removable film can be for example offset printing technique and silk-screen process.
According to a variation of the manufacturing process, influencing directly the sticker structure, the adhesive can be a water based acrylic material.
Furthermore, the adhesive material can be mixed with air dispersed in small bubbles. When the laminar support is put on the removable film, the small bubbles or part of them explode causing many craters 15 and a discontinuous positioning of the adhesive material on the laminar support 1.
This arrangement increases the transpiration of the adhesive and its capacity of growth of hair through its thickness.
According to another variation of the process and with the above-mentioned flocking process, the laminar support is stuck to defined parts 16 of the removable film 2 so that the shape of the adhesive is not determined by cutting but it is pre-formed before hair application.
In this connection, it is possible to use a silk-screen process or an equivalent process to print the parts of laminar support on the removable film. Through these techniques it is possible to give to the borders of each part a tapering 17. That's to say a progressive reduction of the quantity of adhesive, providing the following effects: on the one hand hair is made thinner in proximity to the border of the portion, simulating more effectively the thinning of hair at the border of a head hair, and on the other hand this arrangement makes borders less evident to touch and sight.
By tapering, it is meant a reduction of adhesive quantity at the borders because the silk-screen process releases on the surface a fair quantity and which can be varied of printed adhesive in the shape of small drops.
Advantageously, the tapering 17 can be applied only on curved borders that's to say to the borders really placed on the limits of hair.
To obtain this effect with silk-screen processes, it is enough to reduce the porosity of the silk-screen process pad near the borders.
It is possible to use a silk-screen process loom of a variable density from 43 to 120 yarns.
Thanks to this technique, it is possible to obtain an arrangement of the adhesive that forms the laminar support by craters without air through a suitable regulation of pad's porosity.
Also the above described adhesive can be obtained in single sheets or rolls. The single parts or groups of parts can be packed and covered by a wrapping or by an envelope that protects the surface of laminar support with hairs.
With reference to figures 3, 4A and 4B a different embodiment of the manufacturing process is described allowing to obtain stickers according to the invention.
According to this second embodiment, a first electrostatic plate 20 is provided with hair locks 21 having the same length, connected to the plate at a lock end which, for example, can be inserted in recesses 22 regularly distributed on the surface of the plate 20.
To the electrostatic plate 20, an electric charge is confered causing the immediate raising of the hairs of every single lock 21. In fact, the distal ends 23 of the hairs will assume the same charge moving away from each other so that all these ends will be positioned at a certain distance from the plate surface, corresponding to the hair length.
In this way, the generated electrostatic field can direct these distal ends against a laminar support 1, for example facing to said electrostatic plate, with the surface thereof, freed by the removable film side 2, so that the hairs are run into the laminar support 1 itself.
To finish the sticker 10, at this point it is enough to cut every lock 21 at the level of the electrostatic plate 20 and to comb and card the so obtained hair deposition.
This method can be applied to every kind of the above-mentioned stickers: with a uniform and continuous placing of laminar support or with a placing by portions, in every embodiment.
The described method allows to apply hair of different lengths, for example it is possible to put shorter hair at the borders of the sticker parts.
It is also possible that the sticker can be manufactured through a manufacturing process non implying an electrostatic system. Hair can be put on the right position, run into the laminar support, through a mechanical process with particular combs or through a manual process (fig. 6).
In this case the laminar support is provided on a removable film in turn placed on a fixed surface plate.
The length of hair run into the laminar support can be adjusted before or after their application.
As for the application of the above described stickers, they can be provided in small parts to be put side by side on the skin of the user, realizing a sort of mosaic; their application is therefore quick and easy and it is not necessary to use further substances or tools.
The ends of the hairs run into the laminar support are put substantially in contact with the skin itself, to which is only added the minimum thickness of the laminar support itself.
The result is extraordinarily similar to those of the percutaneous transplantation but without the uneasiness related to that application.
Since the adhesive is thin, light and transpirable, it doesn't cause sensations of inconvenience, too much weight or itch.
The advantage is that the sticker of the laminar support is transparent or almost transparent so that it can have the colour of the skin.
The above-mentioned sticker has also a lasting application but it can be removed and easily changed by simply peeling the adhesive from the skin.
For this reason the adhesive will be removable.
With reference to the above described method, it allows a continuous production of stickers for the application of hair reducing to a minimum the manual intervention.
In a single solution it is possible to produce stickers of the desired shapes, even different to each other, for example in a single kit suitable to be used by a single user.
If ,during flocking, hairs of different colours are mixed, one can have automatically a mèches effect.
