Description: Field of the Invention The present invention relates to a wig-fitting component for fitting a wig to the head, a method of fitting said wig-fitting component to a wig base and a method of wearing a wig. Description of the Prior Art Conventionally, the following techniques have been employed as methods of fitting a wig to the head. As a conventional method (1) of fitting a wig involves holding the natural hair (the hair of a wig-wearing person) by a hair pin or a wig stopper with the teeth of a comb. A further conventional method (2) of fitting a wig involves sticking a double-sided tape with an adhesive adhered thereto on the rim part of the back of a wig base and fitting the wig to the natural hair or directly to the scalp by the adhesion thereof. A further conventionel method (3) of fitting a wig involves applying a hair adhesive onto the rim part of the back of a wig base and fitting the wig to the natural hair. US 5,033,486 discloses the attachment of a wig to a wearer by first removing a length of the wearer's natural hair then using adhesive to attach the wig to the wearer along the band where the natural hair has been removed However, there are problems with all of the above methods, which remain insolved. For example, in the method of fitting a wig to the natural hair by a hair pin and the like (the above method (1)), the wig can be put on and off easily, but since a hair pin and a stopper have some thickness, bulkiness occurs at the wig-fitting spot and a sense of incongruity has been felt at times during the wear thereof over a long period of time. In the method of fitting a wig to the natural hair employing a double-sided tape (the above method (2)), the wig can be put on and off easily and no bulkiness at the wig-fitting spot occurs; however, since the adhesion is poor, the release of sweat and fat from the skin results in the release of the wig from the head, and it is therefore difficult to wear the wig over a long period of time. In addition, since the adhesion of an adhesive onto the back of a wig base is not so strong in this method, the wig may be released from the wig base at times. Moreover, in the method of applying an adhesive (the above method (3)), the applied adhesive is pressed onto the wig and thereby spreads in a wider range than necessary, which may have influence upon the head skin and the root of hair. in addition, the adhesive may cause the deformation and discoloration of the wig base; and, in this method, when the wig is fitted again, the adhesive solidified matter adhered thereto must be released and removed from the wig base, at which point, the wig base may be damaged. The present invention has been provided with a view to solving the various problems encountered in the above conventional methods of fitting a wig, and one object thereof is to provide a wig-fitting component free from bulkiness at the wig-fitting spot to the natural hair and free of sense of incongruity to the wearer during the wear thereof over a long period of time, capable of being fitted surely over a long period of time, and free from influence upon the scalp and the root of hair, and a method of wearing a wig. Moreover, another object thereof is to provide a wig-fitting component wherein the fitting power of a wig is reinforced as compared with that of a conventional fitting component, the removal of the wig can be performed easily and in a short time, the spot of removal is fine, and the wig can be fitted without causing any damage, deformation and discoloration of the wig base. Summary of the Invention In short, a wig-fitting component according to the present invention is "a wig-fitting component comprising a net-like component characterized in that the net-like component is stuck on one side of a flexible planar component having a surface and a back surface and the flexible planar component has adhesive adhered onto the surface and the back thereof". In addition, a thread-like material for inserting and fastening the natural hair of a wig-wearing person may be additionally provided on the net-like component. The present invention also provides a method of wearing a wig comprising the steps of: preparing a wig-fitting component (1) comprising a net-like component (3) and a flexible planar component (2) having a surface and a back and the back being coated with adhesive (21a, 21b) and the net-like component (3) being adhesively fastened to a first said surface of the flexible planar component (2); adhesively fastening said wig-fitting component (1) to a wig-base (5), a second said surface of said flexible planar component being adhesively fastened to an inner surface of the wig base(5); and coating said net-like component (3) with adhesive (9) so as to catch the natural hair (7) of the wig wearer and thereby to be solidified together with the natural hair (7), thereby fixing the wig (6) to the wearer's head. The method may further include the steps of placing the wig (6) on the wig wearer's head before the adhesive coating of said net-like component (3) is completely solidified; and then solidifying said adhesive (9) together with the wig wearer's natural hair (7) so as to fix the wig to the wig wearer's head. The method may further include the steps of placing said wig (6) to which said wig-fitting component (1) provided with a thread-like component (4) has been fastened on the wig wearer's head; inserting the wig wearer's natural hair (71) present in the vicinity of a peripheral zone of said wig base (5) between said thread-like component (4) and said net-like component (3) so as to be held by said thread-like component (4); folding said natural hair (71) back around said thread-like component(4); guiding said natural hair (71) out of said peripheral zone of said wig base (5); coating said net-like component (3) with adhesive (9) along the zone in which said insertion and holding have occurred; and thereby solidifying said adhesive (9) together with said wig wearer's natural hair (71)so as to fix said wig (6) to the wig wearer's head.

Description of a Preferred Embodiment In Fig. 1, the wig-fitting component 1 comprises a net-like component stuck on one side of a flexible planar component 2 with an adhesive (21a, 21b) adhered onto both sides thereof. That is, the wig-fitting component 1 is, as shown in Fig. 1 (b), a laminated component comprising 4 layers of a layer of adhesive 21b, a layer of the flexible planar component 2, a layer of adhesive 21a and a layer of the net-like component 3. The flexible planar component 2 is a component with a small thickness as compared with a length and a width, and preferred materials thereof include those comprising transparent or semitransparent synthesized resins such as plastics, for example, polyethylene, polypropylene and vinyl chloride, formed into flexible ultrathin films or thin sheets. Onto both the surface and the back of said flexible planar component 2 is adhered an adhesive comprising a resin such as an acrylic resin or rubber as a main agent to provide the layer of adhesive 21a and the layer of adhesive 21b. As shown in Fig. 2, it is preferable that, before the use of said wig-fitting component 1, a film-like or sheet-like protective component 22 is stuck on the outer side of the layer of adhesive 21b as the outermost layer to prevent the removal of the adhesive and the adhesion of dirt and dust. In this case, the wig-fitting component 1 is a laminated component comprising 5 layers of a layer of the protective component 22, a layer of adhesive 21b, a layer of the flexible planar component 2, a layer of adhesive 21a and a layer of the net-like component 3. Such a protective component 22 is preferably a plastic film or sheet which can be released easily from the layer of adhesive 21b when the wig-fitting component is used, and in particular, polypropylene or polyethylene films or sheets are preferred; in addition, as shown in Fig. 2, with a view to allowing the wig-fitting component 1 to be released easily during the use thereof to improve workability, it is preferable to provide straight-line notches 22a and 22b on the protective component 22. The net-like component 3 may comprise various mesh patterns such as lattice, honeycomb (hexagonal) and complicated lace patterns. For the mesh size, a net with tiny meshes is preferred from the viewpoint of the feeling of the net touching the scalp and the improvement of adhesion of an adhesive to the natural hair after the net is tangled with the adhesive. Specifically, those with the number of meshes of from 70 to 120 per cm 2 are preferably employed; in particular, those with the number of meshes of about 90 and a diameter of thread constituting the net of from 30 to 50 deniers are preferred to avoid the net-like component becoming thick. Said net-like component 3 is thin, and hence, when it is stuck on the above flexible planar component 2, the adhesive 21a at the underside comes to the surface of the net-like component 3 through the mesh. Hence, when the natural hair comes into contact with the surface of the net-like component 3, the natural hair is tangled by the coming adhesive and becomes easy to adhere; thus, workability in fitting the wig to the natural hair becomes easier. Any one side of the surface and the back of said net-like component 3 is stuck and fitted onto the flexible planar component 2 by means of adhesive 21a, and it may further be sewed thereon to more firmly fix the net-like component 3 and the flexible planar component 2 together. The wig-fitting component 1 is fitted to the back of the wig base; it may be formed into a continuous tape-like form over the whole circumference of the back of the wig base, or it may be formed into a small piece and a plurality of pieces may be fitted to the back of the wig base in a row. When the flexible planar component 2 or the net-like component 3 is formed and processed, a colorant matching the natural color of the scalp or the black color of the hair may be added lest it should be conspicuous from the outside. Fig. 3 and Fig. 4 show another example (hereinafter referred to as Example 2) of a wig-fitting component according to the present invention different from the above Example 1. Fig. 3 (a) is a perspective view of the wig-fitting component, Fig. 3 (b) is a cross-sectional view of section A-A in Fig. 3 (a), and Fig. 3 (c) is a cross-sectional view of section B-B in Fig. 3 (a). Example 2 comprises the wig-fitting component 1 in the above Example 1 with a thread-like material 4 for inserting and fastening the natural hair of a wig-wearing person additionally provided on the net-like component 3. Hence, it is the same embodiment as the above Example 1 except that the thread-like material 4 is also provided, and the wig-fitting component 1 comprises the net-like component 3 stuck on one side of the flexible planar component 2 with an adhesive (21a, 21b) adhered to both sides thereof. That is, the wig-fitting component 1 is, as shown in Fig. 3 (b) and (c), a laminated component comprising 4 layers of a layer of the adhesive 21b, a layer of the flexible planar component 2, a layer of the adhesive 21a, and a layer of the net-like component 3 with the thread-like material 4 provided additionally thereon. The flexible planar component 2, the adhesive (21a, 21b) and the net-like component 3 are the same constituent components as are empolyed in Example 1. In Example 2, too, as In Example 1, as shown in Fig. 4, it is preferable that, before the use of said wig-fitting component 1, a film-like or sheet-like protective component 22 is stuck on the outside of the layer of the adhesive 21b as the outermost layer to prevent the removal of the adhesive and the adhesion of dirt and dust. In this case, the wig-fitting component 1 is a laminated component comprising 5 layers of a layer of the protective component 22, a layer of adhesive 21b, a layer of the flexible planar component 2, a layer of adhesive 21a and a layer of the net-like component 3. Such a protective component 22 is preferably a plastic film or sheet which can be released easily from the layer of the adhesive 21b when the wig-fitting component is used, and in particular, polypropylene or polyethylene films or sheets are preferred; in addition, as shown in Fig. 4, with a view to allowing the wig-fitting component 1 to be released easily during the use thereof to improve workability, it is preferable to provide straight-line notches 22a and 22b on the protective component 22. The thread-like material 4 is a vegetable fiber such as cotton and hemp, a synthetic fiher such as nylon, pblyurethane and polyester, an animal fiber such as twisted wool, bundled fibers, or a thick single fiber; it is fitted on the net-like component 3 at both ends 41 thereof, and the middle part thereof is not fitted so that the natural hair of the wig wearer can be inserted through and fastened to the thread-like material 4. As a method of providing the thread-like material 4 on the net-like component 3 additionally, as shown in Fig. 3 (c) of the present Example, individual long threads are allowed to pass through the adhesive 21b adhesion surface side of the fitting component 1 at both ends 41 thereof and are tied at said surface side. In the Example shown in Fig. 3, the thread-like material 4 is fitted to the net-like component 3 at both ends 41 thereof, however, the thread-like material 4 may be fitted to the net-like component 3 at the middle part rather than at both ends ends 41 provided that it has a free part for inserting and fastening the natural hair. One or more thread-like materials 4 are provided on the net-like component 3; since is inserted through and fastened to the thread-like materials 4, the natural hair when the wig is fitted onto the head of a wig-wearing person. The thread-like materials 4 are fixed with a hair adhesive after fastening the natural hair, and a plurality thereof are preferably provided for performing fastening of the natural hair and the application of the adhesive easily. In Fig. 3, two thread-like materials 4 are provided almost in parallel; however, they may be bundled in a twisted yarn state. (2) Method of Fitting the Wig-Fitting Component to a Wig Base The method of fitting the wig-fitting component according to the present invention described above to a wig base is as below. Fig. 5 is a plan view showing a part of the back of a wig base as one example. That is, in Fig. 5, the central part shows a net and the surrounding rim part shows a flexible sheet-like wig base; the wig-fitting component according to the present invention is not restricted to the wig base with such a form, but a flexible sheet-like wig base wholly formed of polyurethane or unwoven fabric or a wig base wholly formed of a net or a combination thereof can be employed. In Fig 5, the fitting component 1 is fitted to the surrounding rim part of the wig base; however, if the wig-fitting component 1 has no thread-like material provided on the net-like component, additionally, it may be fitted to the central part instead of the surrounding rim part. In Fig. 5, first of all, the protective component (not shown) protecting the adhesive (21b) adhesion surface on the opposite side of the surface with the net-like component of the wig-fitting component 1 stuck thereon is released and the wig-fitting component 1 is fitted to the surrounding rim part 51 of the back of the wig.base 5. That is, it is fitted so that the net-like component is present on the surface of the wig base. The fitting component 1 is stuck easily on the surrounding rim part 51 of the back of the wig base 5 by the adhesive 21b. Next, the wig-fitting component 1 is sewed and sealed on the surrounding rim part 51 of the back of the wig base 5 by an adhesive; it is preferable to seal it at the boundary part 15 with the surrounding rim part 51 from the viewpoint of the prevention of damage to the wig base. This can be done by applying an adhesive onto the boundary part 15 and, in the case of the wig base being made of a resin, applying a resin solution obtainable by dissolving said resin in a solvent and volatilizing the solvent to solidify. The wig-fitting component 1 is stuck to the wig base 5 using an adhesive; in order to fix it firmly, it is stuck at the boundary part 15. It is easy to release as, by employing an adhesive to hold the wig-fitting component 1 and the wig base 5 together, only the narrow spot of the boundary part with the wig base need be coated with the adhesive and the resin solution, and hence, the dissolution (damage) of the wig base by the adhesive and the resin solution can be reduced to the minimum. In the case that the wig-fitting component 1 also has a thread-like material 4 provided on the net-like component 3, it is preferable that the thread-like material 4 is fitted almost in parallel to the surrounding rim of the wig base with a view to inserting and fastening the natural hair to the wig base. Generally, the surrounding rim part 51 which is the head contact surface of the back of the wig base 5 is formed of an artificial skin with polyurethane as a base; thus, as a resin solution to be used for sticking the wig-fitting component 1 on the wig base 5 in the case that the surrounding rim part 51 of the wig base 5 is formed of polyurethane, a solution obtainable by dissolving polyurethane into a mixed solution (solvent) of dimethylformamide (DMF) and methyl ethyl ketone (MEK) is preferably used. When the wig-fitting component 1 is a small piece, the number of the wig-fitting component 1 to be fitted to the back of the wig base 5 is properly determined according to the size of the wig base 5, (3) Method of Fitting the Wig to the Head The method of fitting the wig with the wig-fitting component 1 fitted to the back of the wig base 5 to the head is as below. (i) In the case of a wig-fitting component (embodiment of Example 1) with no thread-like material for inserting and fastening the natural hair to the net-like component provided: Fig. 6 (a) and (b) are schematic explanatory views showing the state of fitting a wig to the head employing the above wig-fitting component.As shown in Fig. 6 (a), a hair adhesive 9 is applied onto the net-like component 3 of the wig-fitting component 1 fitted to the back of a wig base 5 in a wig 6.For the adhesive 9, latex-based, silicone-based, epoxy-based and polyurethane-based hair adhesives are employed; of them, latex-based aqueous emulsions are preferred.Subsequently, as shown in Fig. 6 (b), with the adhesive 9 being in a non-solidified state, preferably in a semisolidified state, the wig 6 is put on the head of a wig-wearing person to fit the adhesive 9 to the natural hair 7, then the adhesive 9 is solidified completely or almost completely to fit the wig 6 to the head.The adhesive 9 spreads to cover the natural hair and every corner of the fine meshes of the net-like component 3. In particular, the adhesive 9 enters the meshes, and hence, strong adhesion effects can be obtained by a so-called anchor action as compared with the case of employing a component with a smooth surface. (ii) In the case of the wig-fitting component (embodiment of Example 2) provided with a thread-like material for inserting and fastening the natural hair to the net-like component: Fig. 7 (a) - (c) are schematic explanatory views showing the state of fitting a wig to the head employing the above wig-fitting component. Fig. 8 is a partially enlarged view of the spot for the natural hair to be inserted and fastened in Fig. 7 (c).As shown in Fig. 7 (a), first of all, the wig 6 is put on the head of a wig-wearing person.Subsequently, as shown in Fig. 7 (b), an operating rod 8 with a hook on the tip is inserted between the net-like component 3 and the thread-like material 4 to hook the natural hair around the surrounding rim part of the wig base 5, preferably the natural hair 71 at the outside of the surrounding rim part of the wig base 5, and then the hook is pulled up along the net-like component 3 to insert the natural hair between the net-like component 3 and the thread-like material 4.The adhesive on the underside of the surface of the net-like component 3 comes to the surface of the net-like component 3 and thereby the natural hair (7 or 71) is easily adhered to the net-like component 3. Next, as shown in Fig. 7 (c), the inserted hatural hair is fastened to the thread-like material 4 and folded, and then drawn again to the outside of the surrounding rim part of the wig base 5, and then the adhesive 9 is applied onto the spot where the natural hair is inserted and fastened, namely, the spot where the net-like component 3, the thread-like material 4 and the natural hair (7 or 71) meet, and solidified to fit the wig to the head of the wearer. The adhesive 9 applied onto the spot where the natural hair is inserted and fastened spreads to every corner of the natural hair (7 or 71), the thread-like material 4 and the fine meshes of the net-like component 3. In particular, the adhesive 9 enters the meshes, and hence, a stronger adhesion effect can be obtained by a so-called anchor action as compared with the case of employing a component with a smooth surface. Similarly as in the above Example, for the adhesive 9, latex-based, silicone-based, epoxy-based and polyurethane-based hair adhesives may be employed; of them, latex-based aqueous emulsions are preferred. As shown in Fig. 8, it is preferable that only the natural hair 71 at the outside of the surrounding rim part of the natural hair 7 around the surrounding rim part of the wig base 5 is pulled up on the net-like component 3 and used for fitting the wig 6. The natural hair 7 grows downward (in a direction from the crown of the head toward the side of the head), and hence, if only the natural hair 71 at the outside of the surrounding rim part is pulled up to fasten to the thread-like material 4, folded in a downward direction as the natural hair grows and drawn to the outside of the surrounding rim part of the wig, the wig can be prevented from coming away from the head without going against the direction of the natural hair's growth. The effects of the present invention include the following. (1) The wig-fitting component according to the present invention is composed of a thin and flexible planar component and a thin net-like component; the spot for a wig to be stuck on the natural hair and fitted to the head is not bulky, and no sense of incongruity occurs in the use thereof over a long period of time. (2) The wig-fitting component according to the present invention can be fitted securely for a long time since the natural hair is stuck by an adhesive to fit a wig. In addition, if a thread-like material for inserting and fastening the natural hair is also provided, the wig-fitting component can be fitted more firmly. (3) In the wig-fitting component according to the present invention, the side for sticking to the natural hair by an adhesive is formed of a net-like component, and hence, the adhesive spreads to every corner of the natural hair (and the thread-like material) and the fine meshes of the net-like component. In particular, the adhesive enters the meshes, and hence, a stronger adhesion effect can be obtained by a so-called anchor action as compared with the case of employing a component with a smooth surface. Moreover, if a fine-mesh and thin component is employed as the net-like component, the feeling of contact with the scalp is excellent. Furthermore, the adhesion of a wig is reinforced as compared with the case of a conventional fitting component, it can be removed from the head easily and in a short time, and the removal spot is fine. (4) When the wig-fitting component according to the present invention is stuck on the natural hair by an adhesive to fit a wig, the adhesive does not spread outside the surface of the net-like component, and hence, there exists no fear of influence upon the scalp and the root of hair. (5) In the wig-fitting component according to the present invention, since the underside of the net-like component for the natural hair to adhere thereto is an adhesive layer, the adhesive comes to the surface of the net-like component and thereby the natural hair is easy to adhere; hence, the operation of fitting the wig becomes easier. (6) According to the method of wearing a wig of the present invention, the wig-fitting component according to the present invention is employed; hence, as described above, the feeling of wear thereof is excellent and it does not come off even if it is worn over a long period of time since it is fitted firmly; moreover, it becomes possible to wash the hair as it is worn. In addition, if only the natural hair at the outside of the surrounding rim part of the natural hair around the surrounding rim part of the wig base is pulled up on the wig-fitting component to fix the wig-fitting component to the natural hair, then folded in a downward direction as the natural hair grows and drawn to the outside of the surrounding rim part of the wig, the wig can be prevented from coming away from the head. (7) The method of wearing a wig according to the present invention employs a flexible planar component with the wig-fitting component according to the present invention coated with an adhesive; hence, the wig-fitting component has only to be fitted only at the boundary part with the wig base, and thereby the damage, deformation and discoloration of the wig base by the adhesive can be reduced to the minimum.
