Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a part base used for a hair part of a wig and a manufacturing tool therefor.

[0002]

2. Description of the Related Art A wig may require a partial base smaller than the entire wig. For example, a partial base that partially covers only a thin portion of the hair of the head, or a wig base body with a mesh net. A hair dividing base used for the constructed net base is known, and the partial base may be used alone. In the net base, a hair part base made of a sheet-like material such as a thermoplastic resin is arranged corresponding to the hair part of the wearer, and by implanting hair here, the hair part of the wig can be made natural. It is possible to obtain the flow of hair and obtain a natural appearance that is the same as the scalp even when the hair splitting portion base is exposed. And as a method for manufacturing the hair part base, a step of evenly applying a synthetic resin solution in which a synthetic resin or a thermoplastic synthetic resin is appropriately dissolved in an organic solvent to the entire molding die, and drying to evaporate the organic solvent Repeatedly after setting the desired film thickness,
A method of cutting out a necessary part as a hair part is widely used.

[0003]

SUMMARY OF THE INVENTION In a manufacturing method in which a synthetic resin solution is applied to the above mold and dried to evaporate an organic solvent, air is entrained during application or drying of the synthetic resin solution to cause air bubbles in the wig base. Is more likely to occur,
This causes a decrease in the strength of the wig base after molding, and there is a problem that the appearance is impaired by the inclusion of air bubbles. In addition, it is possible to increase the resin concentration of the synthetic resin solution to reduce the working time and to apply the resin once or twice to reduce the steps of coating and drying to obtain a desired film thickness. From the viewpoint of quality, it is difficult to obtain a desired film thickness by applying once or twice, such as generation of air bubbles or large variation in film thickness after manufacturing. In practice, lower the resin concentration of the synthetic resin solution. However, the coating and drying steps have to be repeated until the desired film thickness is obtained, and there is a problem that the operation takes a long time. Furthermore, in the case of a wig that uses a net base, it takes longer to manufacture the hair part base than the time required to manufacture the net base, and the same mold is used to manufacture the net base and the hair part base. Since it is necessary to prepare two net bases and a hair part base at the same time, as a result, there is a problem that it costs extra for one molding die. In addition, conventional synthetic resin solution,
In the case of a method in which the steps of uniformly coating the entire molding die, drying and evaporating the organic solvent are repeated to obtain a desired film thickness, and cutting out a necessary portion as a hair dividing portion, a portion necessary as a hair dividing portion is Since it is only a part of the entire molding die, there is a problem that many parts are wasted and cost is increased. For this reason, it is possible to apply the synthetic resin solution only around the hair part of the molding die in order to reduce the wasted portion. Since it becomes large and it is necessary to repeat coating and drying in order to obtain a desired film thickness, the work time cannot be shortened as a result.

Therefore, an object of the present invention is to provide a method for manufacturing a partial base of a wig and a manufacturing tool therefor, which can obtain a uniform film thickness and can be easily manufactured.

[0005]

According to a first aspect of the present invention, a sheet material for a wig base is sandwiched by a frame body having an opening, and the sheet material is heated and softened so that the lower surface of the sheet material is the frame. This is a method for manufacturing a partial base of a wig, which comprises pressing a body together with a mold to make a close contact with the mold, and releasing the mold after cooling.

According to a second aspect of the present invention, a sheet material for a wig base, which is formed by releasably laminating a thermoplastic resin sheet serving as a partial base of a wig and a different thermoplastic resin sheet, is heat-softened to form the sheet material. This is a method for manufacturing a partial base of a wig, which is characterized in that the sheets are brought into close contact with each other and molded, and the sheets are separated from each other.

According to a third aspect of the present invention, the wig base sheet material comprises a thermoplastic resin sheet serving as a partial base of the wig, and a thermoplastic resin sheet having a softening temperature lower than that of the sheet, which is releasably bonded to the sheet. The method according to claim 1, wherein the sheets are separated from each other.

The invention of claim 4 is the method of manufacturing a partial base of a wig according to claim 2 or 3, characterized in that a polyurethane resin elastomer is used for the thermoplastic resin sheet which is the partial base of the wig.

According to a fifth aspect of the present invention, there is provided a partial base manufacturing tool for a wig which holds a wig base sheet material and presses it against a molding die, the manufacturing tool being bendable along the molding frame. A hair wig part base manufacturing tool comprising a pair of frame plates having openings.

[0010]

In the structure of claim 1, since the partial base is molded from the sheet material, unlike the case of applying the synthetic resin solution a plurality of times, it can be molded to a uniform thickness without requiring skill. Further, since the sheet material is sandwiched by the frame body, heated and softened, and pressed against the molding die, the working process and time can be shortened.

According to the second aspect of the present invention, since the sheet material has two layers, that is, the sheet serving as the partial base of the wig and the sheet different from the wig, it is possible to heat from the lower sheet side not used as the base after molding. Excessive heat is not applied to the base sheet, and the partial base sheet is not partially expanded by heating. In addition, by pressing the lower sheet against the forming die, the upper partial base sheet will not be partially expanded, and the partial base sheet will be formed with a substantially uniform thickness. You can Further, since the sheet serving as the partial base does not come into direct contact with the molding die, the sheet does not come into contact with the molding die and is not rapidly cooled, and the quality of the sheet serving as the partial base becomes stable.

According to the third aspect of the present invention, the sheet material has two layers, that is, a sheet serving as a partial base of the wig and a sheet having a lower softening temperature than that of the wig. Therefore, in the step of pressing the sheet material against the mold, the softening temperature is lowered. Even if the lower sheet material with a low stretch extends and the film thickness varies, the upper sheet material can be molded with a uniform film thickness, and by heating from the lower sheet side not used as a base after molding, Excessive heat is not applied to the partial base sheet, the partial base sheet does not spread partially by heating, and the lower sheet is pressed against the mold to form The partial base sheet is not partially expanded, and the partial base sheet can be formed with a substantially uniform thickness. Further, since the sheet serving as the partial base does not come into direct contact with the molding die, the sheet does not come into contact with the molding die and is not rapidly cooled, and the quality of the sheet serving as the partial base becomes stable. Further, since a sheet having a low softening temperature can be formed in a short time, the time for pressing the sheet material against the forming die is short.

In the structure of claim 4, the polyurethane resin elastomer has a relatively low softening temperature, is easy to process, and has elasticity suitable for the finished product as a partial base of the wig, and further has excellent durability. In addition, it is not discolored even when receiving light, and has excellent light resistance.

In the structure of claim 5, the sheet material for the wig base is heated and softened in a state of being sandwiched by the frame body, and since the frame body can be bent along the molding die, after heating and softening,
The sheet material can be molded by pressing the sheet material together with the frame body against the forming die and holding the sheet material.

(Referred to as 11) is a frame body which is a manufacturing tool for sandwiching the periphery thereof, and the frame body 12 includes a pair of frame plates 13 and 13 as shown in FIGS. 3 and 4.
The frame plates 13 and 13 in the form of thin plates are provided with substantially rectangular openings 14 and 14, respectively.
13 are connected at one side edge at a bent portion 15, and upper and lower frame plates 13, 13
And the bent portion 15 constitutes a hinge portion that allows the pair of frame plates 13 and 13 to be overlapped with each other. The frame plates 13 and 13 have heat resistance higher than that of the sheet material 11 and have such elasticity that the frame plate 13 can be closely attached to the molding die 1 when pressed against the molding die 1. In this case, a stainless plate having a thickness of about 0.3 mm (mm) is used, and the frame plate 13 is formed to be longer in the length direction than in the width direction so as to be suitable for molding the hair dividing portion base. ,
The opening 14 has a larger area than the hair part 3S of the mold 1. As shown in the development view of FIG. 3, the frame 13 has the openings 14 and 14 formed in a single stainless steel plate member having a rectangular shape, and a central bent portion shown by a chain line in FIG.
It is bent and formed at 15 points.

The sheet material 11 for the wig base (hereinafter referred to as the sheet material 11), as shown in FIG. 5 in this example, is a thermoplastic resin sheet 21 (hereinafter, referred to as a partial base of the wig).
Sheet 21), an auxiliary thermoplastic resin sheet 22 having a softening temperature lower than that of the sheet 21 (hereinafter referred to as an auxiliary sheet 22) is releasably attached, and the sheet 21 and the auxiliary sheet 22 are bonded to each other. It is preferable that the respective members are adhered to each other by simply laminating and pasted without using a material or the like so that they can be separated. The sheet 21 that is a partial base of the wig can be appropriately used with a polyurethane resin elastomer or soft vinyl chloride as long as it is a thermoplastic resin, but the polyurethane resin elastomer is preferably a polyurethane resin elastomer because of its durability, ease of processing, and flexibility of the resin. preferable. Also, sheet 21
Has a matte finish on at least one side to give natural luster to sunlight or fluorescent light, and has a flesh color to give a camouflage effect even if the hair part of the wig is exposed. It is preferable that the matting is performed by pre-matting the sheet 21 before molding, or adding a matting agent to a synthetic resin solution in which a synthetic resin or a thermoplastic resin is appropriately dissolved in an organic solvent after molding. The coated product is applied to the surface and then dried to evaporate the organic solvent for matting. On the other hand, as the auxiliary sheet 22, using a thermoplastic resin sheet having a lower softening temperature than the sheet 21,
Since a polyurethane resin elastomer is used as the sheet 21 which becomes the partial base of the wig after molding, the auxiliary sheet 22 is preferably polyvinyl chloride, acryl, polystyrene, or a polyolefin resin, such as polyethylene or polypropylene. Of these, polyethylene is particularly preferable in view of the spreadability of the resin when it is softened by heating. In the present invention, when polyethylene is used for the auxiliary sheet 22, it is softened by heating and pressed against the mold 1. The auxiliary sheet 22 is less likely to be wrinkled, and the film thickness of the auxiliary sheet 22 made of polyethylene minimizes the molding accuracy of the wig base after molding and the shrinkage of the sheet material 11 that occurs during cooling after molding. 0.2 to
From the above, it is preferable that the thickness is 0.4 mm or less. The auxiliary sheet 22 may be transparent, semi-transparent, or colored, and if necessary in other steps performed after the sheet material 11 is formed following the molding die 1, the auxiliary sheet 22 is filled in the molding die 1. It suffices that the above described production lines Rk, Rb, and Rw can be visually recognized. Furthermore, as the molding die 1, a thermosetting resin such as an epoxy resin or a wooden male head can be used in addition to the plaster.

In the figure, 23 is a heater as a heating means for heating the sheet material 11, 24 is a net base constituting the entire wig, and 25 is a hair dividing part base which is a partial base formed from the sheet 21. is there.

Next, a method of manufacturing the hair dividing part base 25, which is a partial base, using the wig sheet material 11 and the frame body 12 will be described. First, the sheet material cut to the size of the frame plate 13 will be described. 11 is sandwiched between the upper and lower frame plates 13, 13. In this case, as shown by the chain line in FIG. 4, it is possible to open the other side of the bent portion 15 against the elasticity of the frame body 12 and insert and sandwich the sheet material 11 between the upper and lower frame plates 13, 13. it can. In the sandwiched state, as shown in FIG. 5, the auxiliary sheet 22 side is directed to the heater 23 to heat and soften the sheet material 11, and the auxiliary sheet 22 side of the heat-softened sheet material 11 is quickly It is pressed against the molding die 1, and at the same time, the frame 12 is also pressed against the molding die 1 in a bent state following the molding die 1 due to its elasticity. If it is kept pressed for 30 seconds to 1 minute as it is, the auxiliary sheet 22 has a low softening temperature.
Are molded in accordance with the molding die 1, and thereafter, the sheet material 11 is removed from the molding die 1, that is, released, and the sheet material 22 is removed from the frame body 12.
It is left to cool for 2 to 24 hours before being peeled off. In this case, the auxiliary sheet 22 having a low softening temperature which is directly heated is molded in a short time when pressed against the molding die 1, so that the time for pressing the sheet material 11 is short, while the direct heating is not performed. The sheet 21 that is not pressed directly against the mold 1 is
The sheet is adhered to the auxiliary sheet 22 without peeling until the shape is stabilized by residual heat, and is left to cool for 2 to 24 hours, so that the sheet material 11 is formed into a shape following the forming die 1 and the sheet material 11 is pressed onto the forming die 1. Cooling in the applied state can be completed in a short time. Then, the sheets 21 and 22 forming the laminated structure are separated from each other, and human hair or artificial hair is planted on the sheet 21 which becomes the hair dividing portion base 25, and the lines Rb and Rw are formed on the sheet 21 before the planting. A copy is made as shown in FIG. 8, and unnecessary portions are cut off based on the production line Rb to produce a hair splitting portion base 25, and this hair splitting portion base 25 is used for hair splitting of an entire wig including the net base 24 and the like. Attach it to the part by gluing or sewing. Further, at least one surface of the hair part base 25 is treated with a matte 26.

As described above, in this embodiment, according to claim 1, the periphery of the wig base sheet material 11 is clamped by the frame body 13 having the opening 14, and the sheet material 11 is heated and softened to form the sheet. The lower surface of the material 11 is pressed against the molding die 1 together with the frame body 12 so as to be in close contact therewith, and after cooling, it is released from the mold, so that the sheet material 11 is sandwiched between the frame bodies 12. Since it is heated and softened and pressed against the molding die 1 for molding, the working process and time can be shortened. Further, since the hair part base 25 is formed from the sheet 21 of the sheet material 11, unlike the conventional case of applying the synthetic resin solution a plurality of times, the hair part having a uniform thickness can be obtained without skill. The base 25 can be molded, and the sheet material 11 can be pressed against only the hair-dividing portion 3S corresponding to the molding die 1, so that the surplus portion after molding can be extremely reduced and the material cost can be reduced. Moreover, unlike the conventional method, the steps of applying and drying the synthetic resin solution are omitted, the equipment required for local evacuation and drying accompanying the use of these solutions is not required, and the heating means such as the heater 23 makes it easy. It can be manufactured. Further, since the sheet material 11 is heated while being sandwiched by the frame body 12 and pressed against the molding die 1 as it is, the sheet material 1 is pressed when the molding die is pressed.
1 can be pressed evenly without shifting.

As described above, in this embodiment, the thermoplastic resin sheet serving as the hair part base of the wig corresponds to claim 2.
A wig base sheet material 11 formed by releasably attaching a thermoplastic resin sheet 22 different from 21 is heated and softened,
The sheet material 11 is closely attached to the molding die 1 to form the sheet 21,
22 is a method for manufacturing a partial base of a wig, which is characterized by peeling each other from each other.
Since the base material 11 is heated from the side of the auxiliary sheet 22 below, the sheet 21 serving as the upper hair part base 25 is not overheated because the base material 11 is heated. The sheet 21 that becomes 25 does not partially extend. In addition, by pressing the lower sheet 22 against the molding die 1 to form, the upper hair part base 25 sheet 21 is not partially expanded, and the hair part base 25 has a uniform thickness.
The sheet 21 that becomes 25 can be formed. Further, since the sheet 21 which will be the hair part base 25 does not come into direct contact with the mold 1, the hair part base 25 of stable quality can be molded without contacting the mold 1 and being rapidly cooled.

As described above, in this embodiment, according to claim 3, the wig base sheet material 11 has a softening temperature lower than that of the thermoplastic resin sheet 21 which becomes the wig hair part base 25. The method for manufacturing a partial base of a wig according to claim 1, characterized in that the low thermoplastic resin sheet (22) is releasably adhered to each other, and the sheets (21, 22) are separated from each other. A sheet 21 to be the hair part base 25 and an auxiliary sheet 22 having a lower softening temperature than this
In the step of pressing the sheet material 11 against the forming die 1, even if the lower sheet material 22 having a low softening temperature extends and the film thickness varies, the upper sheet material 21 is made uniform. Since the base material 11 can be heated from the lower auxiliary sheet 22 side, excessive heat is not applied to the sheet 21 which will be the upper hair splitting portion base 25. The sheet 21 serving as the hair splitting portion base 25 does not partially spread when heated. The sheet 22 below is formed into the mold 1
By pressing and shaping on the hair part base on
It is possible to form the sheet 21 that will become the hair split portion base 25 with a uniform thickness without the sheet 21 that will become 25 becoming partly extended. In addition, since the sheet 21 serving as the hair part base 25 does not come into direct contact with the molding die 1, it does not come into contact with the molding die 1 and is not rapidly cooled.
Can be molded. Also, a sheet with a low softening temperature
Since the sheet 22 can be molded in a short time, the time for pressing the sheet material 11 against the molding die 1 is short, and the sheet 21 is stuck to the auxiliary sheet 22 in a preheated state and left to cool for a predetermined time. Can be molded into the shape of the auxiliary sheet 22, that is, the shape following the molding die 1.

Thus, in this embodiment, in accordance with claim 4, polyurethane resin elastomer is used for the thermoplastic resin sheet 21 which becomes the hair part base 25 of the wig. Since it is a method of manufacturing the partial base of the wig, the polyurethane resin elastomer has a relatively low softening temperature, is easy to process, and has elasticity suitable for the finished product as the partial base 25 of the wig. A good wearing feeling is obtained, and further, durability is excellent, and even when light is received, discoloration is small and light resistance is also excellent.

As described above, in this embodiment, according to claim 5, a frame body 12 which is a manufacturing tool for the hair splitting portion base 25 of the wig, which holds the periphery of the wig base sheet material 11 and presses it against the mold 1. In addition, since the frame body 12 is a manufacturing tool for a partial base of a wig, which is characterized by comprising a pair of frame plates 13 and 13 which can be bent along the molding frame 1 and has an opening 14, a wig base sheet The material 1 is heated and softened in a state of being sandwiched by the frame 12, and since the frame 12 can be bent along the molding die 1, it can be pressed and held together with the sheet material 11 against the molding die 1 after the heating and softening. The sheet material 11 can be easily formed. Further, the sheet material 11 can be stably sandwiched by the upper and lower frame plates 13, 13.

Further, as an effect of the embodiment, by using polyethylene for the auxiliary sheet 22, this polyethylene has excellent spreadability, and since wrinkles are hard to enter when it is pressed against the mold 1, the hair part Seat 21 that will be the base 25
Can be faithfully molded by following the molding die 1, and the thickness of the auxiliary sheet 22 made of polyethylene can be reduced to 0.
By adjusting the thickness from 2 to 0.4 mm, the molding accuracy can be kept good, and when the thickness exceeds 0.4 mm, the sheet material 11 is relatively thick when pressed against the molding die 1. The extension of the auxiliary sheet 22 may be insufficient and the forming accuracy of the upper sheet 21 may be impaired. On the other hand, if it is 0.2 mm or less, the auxiliary sheet 22 may be wrinkled when pressed against the forming die 1. However, there is a possibility that molding accuracy may be impaired due to shrinkage during the cooling of the sheet material 11 and the control of the heating temperature becomes complicated, but these problems can be solved. Further, when the auxiliary sheet 22 is made of polyethylene, the time for pressing the heat-softened sheet material 11 against the molding die can be shortened and the workability can be improved. Further, by processing the matting portion 26 on at least one surface of the hair part base 25, it is possible to obtain a natural appearance that does not change from the scalp even when the hair part of the finished wig is exposed. Further, in this embodiment, since heating can be performed from the side of the auxiliary sheet 22 of the sheet material 11 at the time of molding, even if the sheet 21 is previously subjected to matting 26 such as graining, the matting 26 is a heating heater. It is not exposed to the heat of, and a good matte state is maintained even after molding. Further, in the frame body 12, since the opening 14 is formed in the plate material and is bent,
It can be manufactured inexpensively and easily.
