Descrição
    TECHNICAL FIELD
  • [0001]
    The present invention relates to a wig worn on a head and a method for manufacturing the wig, more specifically the wig wherein the part that ties hair to a wig base is not placed on the surface of the wig base and has sufficient adhesion, and the manufacturing method of the wig.
  • BACKGROUND ART
  • [0002]
    Conventionally, a wig is manufactured by implanting human or artificial hair to a wig base in a shape of a head made of artificial synthetic resin skin or a net material, and by applying a hair adhesive, as required, to the back of the wig base on which the hair has been planted. As disclosed in patent literature 1, planting methods such as single planting, half-knot planting, and split-knot planting are known.
  • [0003]
    All of the planting methods disclosed in patent literature 1 make pairs of holes on a wig base using a hook, etc., make hair pass through these holes, and tie them on the surface of the wig base, meaning that the knots are placed on the surface of the wig base.
  • [0004]
    Under any of the methods disclosed in patent literature 1, knots of hair are on the surface of the wig base. Consequently, the knots look like blots, and because of that unnaturalness, the wig is easily recognizable as a wig. In addition, when hair is brushed, the teeth of a brush may catch these knots, hampering smooth brushing. If brushing is given repeatedly, the knots may become loose, thus resulting in coming off of wig hair. Furthermore, depending on the knotting method, erection of hair may become insufficient and consequently desirable volume may not be obtained.
  • [0005]
    To solve these problems, patent literature 2 discloses a method for planting hair on a second base, which forms a bottom layer of a wig base comprised of a top first base and a bottom second base, inserting a hook from the surface of the top first base, catching the hair planted on the second base, and drawing the hair out of the surface of the first base.

  • [0007]
    Patent literature 2: JP2006−183215A
  • DISCLOSURE OF INVENTION Technical Problem
  • [0008]
    However, although this method solves the problem described above resulting from the structure that hair knots are on the surface, along with the problem of insufficient hair erection, the method requires providing two wig bases. In addition, the process of drawing out the hair planted on the second base onto the surface of the first base is a cumbersome task decreasing work efficiency. In addition, application of a hair adhesive was still needed.
  • [0009]
    To solve the problems described above, the present invention provides a wig comprising a wig base and hair planted on the wig base, characterized in that hair knots are not on the surface of a wig base and that sufficient adhesion is obtained, along with the manufacturing method of the wig.
  • Solution to Problem
  • [0010]
    To achieve the above objective, the present invention provides a wig comprising a wig base and hair tied to the wig base, characterized in that the knots of hair are on the back of the wig base.
  • [0011]
    According to the present invention, the bridging portion of hair linked to a knot is on the surface of the wig base.
  • [0012]
    It is preferable that the wig base be an artificial skin base at least a part of which is made of a synthetic resin, and the knot of hair be placed on the back of the artificial skin base by being made to pass through a pinhole made on the artificial skin base.
  • [0013]
    The pinhole made on the artificial skin base contracts while catching hair. Consequently, the hair can be retained upright.
  • [0014]
    It is preferable that the wig base be a net base made of a net member, at least partially, that the hair be tied by being wrapped around a filament constituting the net base, and that the knot be placed on the back of the net base.
  • [0015]
    It is desirable that the mesh size of the net base be smaller than the size of the knot.
  • [0016]
    The method of manufacturing a wig according to the present invention comprises a process of tying hair to a wig base and a process of transferring the hair-tying knot to the back of the wig base, while settling the bridging portion linked to the knot onto the surface of the wig base, by pulling one side of the hair.
  • [0017]
    Specifically, the method for manufacturing the wig according to the present invention comprises a first step for attaching hair to a wig base by passing a hook portion of a hair-implanting needle from the surface to the back of the wig base and passing the hook portion back onto the surface at another position, a second step for folding the hair and catching the loop formed at the turning position by the hook portion, a third step for pulling the hair-implanting needle, with the loop of the hair kept caught by the hook portion, back onto the surface of the wig base through the pinholes through which the hair-implanting needle was inserted previously, a fourth step for catching one side of the hair with the hook portion, a fifth step for pulling the hair-implanting needle out of the loop with that side of the hair caught by the hook portion, a sixth step for forming a knot by pulling one side of the hair while holding the other side, and a seventh step for moving the knot to the back of the wig base by pulling the other side of the hair while holding the one side of the hair.
  • [0018]
    Under the method of the present invention, it is desirable to insert a step of rotating the hair-implanting needle, after the loop is caught by the hook portion, on the axis of the longitudinal direction of the hair-implanting needle.
  • [0019]
    Under the method of the present invention, it is desirable to settle the bridging portion linked to the knot of the hair on the surface of the wig base.
  • [0020]
    Under the method of the present invention, it is desirable to form at least a part of the wig base with an artificial skin base made of a synthetic resin, and to pass the knot of the hair through a pinhole made on the artificial skin base, thus making it settle on the back of the artificial skin base.
  • [0021]
    Under the method of the present invention, it is desirable to retain the hair upright by allowing the pinhole made on the artificial skin base to close while retaining the hair.
  • [0022]
    Under the method of the present invention, it is desirable to form at least a part of the wig base with a net base made of a net member, to fasten the hair to filaments constituting the net base by wrapping the hair around the filament, and to transfer the knot to the back of the net base.
  • [0023]
    Under the method of the present invention, it is desirable that the mesh size of the net base be smaller than the size of the knot.
  • ADVANTAGEOUS EFFECTS OF INVENTION
  • [0024]
    According to the wig of the present invention, since the relatively large knots are placed on the back of the wig base, the knots are invisible through the gap between the hairs planted from the surface of the wig base, making the wig hardly recognizable as a wig. In addition, smooth brushing is allowed even when the wig is worn because the teeth of a brush do not catch the knots, thus minimizing the load on the hair implanted. Damage on the hair or loosening of the knots and resulting coming off of hair can thus be prevented. Furthermore, since the knots are placed on the back of the wig base, the teeth of a brush do not contact the knots directly when brushing or washing is performed. Loosening of the knots can thus be prevented. In addition, since adhesion of the hair to the wig base is so strong that no adhesive is required to fasten the hair after implantation. Since only one wig base is needed, the entire wig is made thin and lightweight, making the boundary between the head and the outer periphery of the wig less recognizable. Another advantage of the present invention is that since the part immediately adjacent to the knot of implanted hair is supported by the wig base, favorable erection of the hair is achieved, thus providing sufficient hair volume.
  • [0025]
    According to the manufacturing method of the present invention, a wig that does not have knots on the surface can be manufactured. Furthermore, since the knots exist on the back of the wig base, the hair can be adhered to the wig base securely, and the need for applying an adhesive for fastening after implantation can be eliminated, simplifying the manufacturing process.
  • [0026]
    By rotating the hair-implanting needle in the second step, the hair is twisted, which enhances the adhesion of the hair to the wig base.

  • BEST MODES FOR CARRYING OUT THE INVENTION
  • [0047]
    A preferred embodiment of the present invention will hereinafter be described in detail by referring to the attached drawings. As a wig base, an artificial skin base at least a part of which is made of a synthetic resin, or a net base at least a part of which is made of a net member, is used. As an artificial skin base, a polyurethane film or sheet formed in a convex shape, curving smoothly along the head of a user, is ideal. A polyurethane resin has excellent elasticity and flexibility. Therefore, when hair is attached to the polyurethane resin by inserting a hair-implanting needle into the resin, the hair that has passed through the resin is supported tightly by the contractive force of the resin. When a net base is used, it is desirable to use one having a mesh size smaller than the size of the knot of the hair to be implanted. For example, the mesh size kept within 2 to 2.5 times the diameter of the hair is smaller than that of the knot of the hair to be implanted. Either natural or artificial hair can be used.
  • [0048]
    FIG. 1 provides plan views illustrating the manufacturing method of the wig in this embodiment. An artificial skin made of a polyurethane resin is used.
  • [0049]
    In the first step shown in FIG. 1 (A), the hook portion 1 a of the hair-implanting needle 1 is inserted from the surface 2 a into the back 2 b of the wig base 2, and then at a position a specified distance apart from the position of the insertion, the hook portion 1 a is made to penetrate from the back 2 b onto the surface 2 a of the wig base to reappear on the surface 2 a. Two holes, namely two pinholes, are thus made on the wig base 2, with the hair-implanting needle 1 inserted into these two pinholes. If a wig base made of a net member is used, the hair-implanting needle 1 is inserted into one mesh hole and back onto the surface through an adjacent mesh hole. In this case, the two pinholes or mesh holes through which the hair-implanting needle 1 is passed are defined as a first passing portion 2 c and a second passing portion 2 d, respectively. With an artificial skin wig base, it is desirable that the distance between the first and the second passing portions 2 c and 2 d be maintained at 0.5 mm to 2 mm at the maximum. If this distance is too long, creases may be formed on the wig base 2 when the hair is pulled for tightening after being tied, thus causing deformation of the wig base 2 or loosening of the tied portion.
  • [0050]
    In the second step shown in FIG. 1 (B), one or approximately 2 to 5 hairs 3 are bundled and folded, and a loop 3 b formed at the turning position 3 a is caught by the hook portion 1 a protruding on the surface of the wig base 2. In this case, both sides of the hair folded at the turning position 3 a are defined as one side 3 c and the other side 3 d respectively. The length of one side 3 c and the other side 3 d may be identical, or one of them may be longer than the other. If the turning position 3 a is determined to deviate from the midpoint of the hair, the length of the one side 3 c differs from that of the other side 3 d, providing the wig with natural finishing tone.
  • [0051]
    In step 3 shown in FIG. 1 (C), in a state in which the loop 3 b of the hair 3 is caught by the hook portion 1 a, the hair-implanting needle 1 is pulled through the wig base 2 onto the back 2 b of the wig base 2 at the second passing portion 2 d, and the hair-implanting needle 1 is then pulled through the first passing portion 2 c. The hair-implanting needle 1 is thus pulled out of the wig base 2 completely. As a result, the loop 3 b of the hair 3 caught by the hook portion 1 a is pulled through the second passing portion 2 d and then the first passing portion 2 c, and exposed to the surface 2 a of the wig base 2. As shown in FIG. 1 (C), the hair 3 that has passed through the second passing portion 2 d and then the first passing portion 2 c appear on the surface 2 a of the wig base 2 as a loop 3 b.
  • [0052]
    As shown in FIG. 1 (D), in a state in which the loop 3 b is caught by the hook portion of the hair-implanting needle 1, the hair-implanting needle 1 is rotated counterclockwise by one turn on the axis of the longitudinal direction of the hair. By undergoing this process of twisting the loop 3 b, the adhesion of the hair 3 to the wig base can be enhanced. This twisting process may be performed immediately after the loop 3 b is caught by the hook portion 1 a of the hair-implanting needle protruding from the surface 2 a of the wig base 2 in the second step. The number of turns and the rotational direction can be set as required.
  • [0053]
    In the fourth step shown in FIG. 1 (E), one side 3 c of the hair 3 is caught by the hook portion 1 a of the hair-implanting needle 1 in a state in which the hair-implanting needle passes through the loop 3 b.
  • [0054]
    In the fifth step shown in FIG. 1 (F), one side 3 c of the hair 3 caught by the hook portion 1 a is pulled through the loop 3 b along with the hair-implanting needle 1. Then as shown in FIG. 1 (G), the one side 3 c of the hair 3 is pulled out of the loop 3 b completely along with the hair-implanting needle. The one side 3 c of the hair 3 is then disengaged from the hook portion 1 a of the hair-implanting needle 1.
  • [0055]
    In the sixth step shown in FIG. 1 (H), the one side 3 c of the hair 3 is pulled while the other side 3 d is held by the fingers of a hair-implanting engineer to form a knot 3 e on the surface 2 a of the wig base 2.
  • [0056]
    Finally, in the seventh step shown in FIG. 1 (I), in a state in which the wig base 2 is fastened on a workbench, the other side 3 d of the hair 3 is pulled strongly while the one side 3 c of the hair 3 is held by the fingers of the hair-implanting engineer. As a result, the knot 3 e passes through the first passing portion 2 c onto the back 2 b of the wig base 2. When the loop 3 b is twisted clockwise in the fourth step, the other side 3 d of the hair 3 is caught by the hook portion of the hair-implanting needle 1 and pulled out of the loop 3 b in the fourth step.
  • [0057]
    As shown above, by repeating from step 1 to step 7 for attaching the hair 3 to the wig base 2, the wig 10 in which the knots 3 e are placed on the back 2 b of the wig base 2 can be produced. In this case, the one side 3 c and the other side 3 d of the hair 3 pass through the first passing portion 2 c and the second passing portion 2 d respectively, make a knot 3 e on the back 2 b of the wig base, and pass the first passing portion 2 c and the second passing portion 2 d respectively back onto the surface 2 a of the wig base. In this state, the knot 3 e of the wig 10 is positioned on the back 2 b of the wig base 2, and the intermediate part of the hair 3 extending from this knot 3 e, namely the bridging portion 3 f linked to the knot 3 e, is positioned on the surface 2 a of the wig base. If the wig base is made of a net member, the hair is attached to the filament sandwiched by meshes adjacent to each other by winding the hair around the filament. The knot 3 e is positioned on the back 2 b of the wig base made of the net member, whereas the bridging portion 3 f linked to this knot 3 e is positioned on the surface 2 a.
  • [0058]
    In the wig 10 thus formed, the bridging portion 3 f is on the surface 2 a of the wig base 2. The bridging portion 3 f is in the form of a thin line having a thickness equivalent to the diameter of the hair 3, and the knot 3 e of the hair 3 is on the back 2 b of the wig base. Since the knot 3 e is not on the surface 2 a of the wig base 2, it is not exposed when the wig is worn. The knot 3 e is invisible even through the gap between hairs, and consequently is hardly recognizable as a wig. In addition, smooth brushing is ensured because the teeth of a brush do not catch the knot 3 e. No load is applied to the hair 3 implanted to the wig base, and cutting or coming off of the hair 3 can thus be prevented.
  • [0059]
    If artificial skin is used as a wig base, since the passing portions 2 c and 2 d formed in the first step contract due to the elasticity of the artificial skin, the knot 3 e placed on the back of the artificial skin is not allowed to move to the surface 2 a of the wig base. In the case in which a net member is adopted also, if the net size smaller than that of the knot 3 e is selected, the knot 3 e does not move to the surface 2 a of the wig base because the knot 3 e cannot pass through the mesh. In addition, since the one side 3 c and the other side 3 d of the implanted hair immediately adjacent to the knot 3 e are supported by the contraction of the passing portions 2 c and 2 d of the wig base 2, and are thus made to erect upward, desirable volume of the wig can be obtained. After the hair is implanted to the wig base 2 and the knot 3 e is moved to the back 2 b of the wig base 2, the back 2 b of the wig base 2 may be coated with an urethane resin, for example. This coating prevents the knot 3 e from directly contacting the scalp of the user, eliminating the sense of discomfort and providing good sense of fitting. If the wig base 2 is made of a net base, this back coating prevents the bridging portion 3 f from rotating around the filament.
  • Example 1 Example 1
  • [0060]
    As example 1, a wig was produced by the method in the form of implementation described above. Soft 0.20 mm-thick artificial skin made of a polyurethane resin was used as a wig base, and a number of 0.08 mm-thick artificial hairs made of a polyamide resin were implanted. FIG. 2, FIG. 3, and FIG. 4 are cross-sectional views showing the implanted hair of the wig, viewed at an oblique angle from above, at an oblique angle from underneath, and from the bottom respectively. (A) of FIG. 2, FIG. 3, and FIG. 4 is a scanning electron microscopic image taken at 90-, 80-, and 80-fold magnification respectively. (B) is a figure for describing the members. It is apparent from these figures that the knot 3 e of the wig of the example is on the back 2 b of the wig base 2, and the bridging portion 3 f linked to the knot 3 e is on the surface 2 a.
  • Comparative Example 1
  • [0061]
    As comparative example 1, the same type of hair as the example of the present invention was implanted to the same type of artificial skin wig base as the embodiment by a conventional implanting method called a half-knot planting. Since the details of this half-knot planting method are given in the paragraph [00071] and FIG. 16 in the above patent literature 1, description is omitted here. FIG. 5 (A) is an image showing a plan view of the wig in comparative example 2 observed at 50-fold magnification. It is apparent that the knot 31 is exposed on the surface 2 a of the wig base 2.
  • Comparative example 2
  • [0062]
    As comparative example 2, the same type of hair as the example of the present invention was implanted to the same type of artificial skin wig base as the example by a conventional implanting method called split-knot planting. Since the details of this split-knot planting method are given in the paragraph [00081] and FIG. 17 in the above patent literature 1, description is omitted here. FIG. 6 (A) is an image showing a plan view of the wig in comparative example 2 observed at 70-fold magnification. It is apparent that the knot 32 is exposed on the surface 2 a of the wig base 2.

    Table 1 lists the measurement results of the adhesion the hair to the wig base in the implementation and comparative examples 1 and 2. The adhesion of ten given hairs was measured, and the average of the measurements was found. As measurement samples, the above artificial skin with implanted hair and the same artificial skin with implanted hair with thermal-hardening urethane applied on the back in thickness of 0.2 mm after implantation were used for all of the embodiment and both comparative examples. The adhesion measurement conditions were as follows:

    Measurement method: Single tensile measurement
    Measuring instrument: Compact desktop tester, EZ Test, Shimadzu Corporation
    Measurement condition: Sample (Distance between chucks); 50 mm,
    Tension speed; 100 mm/min.
    The chuck is an instrument for catching hair.

    The results obtained indicate that the example of the present invention made little difference regardless of whether a hair-fastening process was employed or not. The example also exhibited adhesion much higher than that of comparative examples 1 and 2 employing a hair-fastening process.
  • [0065]
    As shown above, if knots are placed on the back face of a wig base, higher adhesion of hair to the wig base is ensured, and the need for an adhesive for fastening hair after implantation is eliminated. Consequently, not only a process of applying an adhesive can be omitted but also the weight of the entire wig can be reduced and the boundary between a user's head and the periphery of the wig becomes less noticeable.
  • [0066]
    As described above, according to the wig and the manufacturing method of the wig of the present invention, the knots of hair are positioned on the back of the wig base, and various embodiments are available without departing from the scope of the invention. For example, materials of a wig base, the number of hairs to be implanted, etc. can be selected as required.
