As described above, according to the manufacturing method of the wig base of the present invention, by molding the wig base by using a fusion base composed of a shell portion made of a low melting point fiber and a core portion made of a high melting point fiber rather than a shell part, the molding operation is simple and productive This is improved and the shape deformation after molding does not easily occur, it is possible to obtain shape stability, and also has the advantage that the deformation can be freely formed as needed, such as whether the user's hair form or full wig or partial wig by reheating.

Hereinafter, preferred embodiments of the present invention will be described in detail so that those skilled in the art may easily implement the technical idea of the present invention. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Method for manufacturing a wig base according to the present invention, as a conventional manufacturing a wig base using a fusion yarn mainly used for filters, reinforcement, interior products, automobile seats, etc., the base sheet manufacturing step; And comprising a molding step; if described in detail with respect to the manufacturing method of the wig base having such a configuration as follows.

[1] base sheet fabrication

The melting point is a step of manufacturing the base sheet of the wig from the monofilament by the composite spinning of the different fibers.

The monofilament is a composite yarn composed of a melting yarn, that is, a shell part made of a low melting point fiber on the outside and a core part made of a fiber having a higher melting point than that of the shell part. Monofilament is used.

As the fusion yarn, the shell portion is a thermoplastic polyester fiber having a melting point of 150 to 180 ° C, and the core portion is a regular polyester, nylon, polybutylene terephthalate (melting point of 220 to 230 ° C) terephthalate (PBT) is optionally used among the fibers, and depending on the material of the core, the shaped wig base obtained in the post process may be softened or hardened.

The core portion is not limited to the above materials, and in addition, the core portion may select and use other fibers having a higher melting point than the shell portion.

The fused yarn having the above configuration has a feature of high heat seal property, excellent shape stability, and hardness adjustment.

In addition, in the fusion yarn, in the case of a fusion yarn in which the shell portion is a thermoplastic polyester fiber having a low melting point and the core portion is a general polyester fiber, it has been used mainly for a filter or the like. Was applied.

Using such fusion yarns, as in the prior art, while arranging warp and weft yarns, a net-shaped base sheet for making a wig base is made by knitting or weaving in the form of a square or hexagonal net.

[2] moldings

It is a step of performing a molding operation | work so that a wig base sheet may be heated and become a predetermined form, such as a cap.

The net-shaped wig base sheet obtained in the first step is placed on the upper part of a mold manufactured in a round shape such as a cap, and then heated to a temperature higher than the melting point of the shell portion.

Here, the heating temperature may vary depending on the fibers forming the fused yarn, but as described above, when the shell portion is a low melting point polyester fiber and the core portion is a general polyester fiber, the temperature is 150 to 180 ° C.

Thus, heating is performed at a temperature higher than the melting point of the fibers forming the shell portion and lower than the melting point of the fibers forming the core portion. Accordingly, the shell portion is melted so that the intersection portions of the warp and weft yarns are fused to each other and integrated according to the shape of the mold. The wig base is shaped.

As described above, the net-shaped wig base sheet obtained in the first step may be placed on the upper part of the mold to be fused by heating to a temperature higher than the melting point of the shell, but the wig base sheet may be heated to a temperature higher than the melting point of the shell. The intersection of the warp and the difference may be fused first, and then placed on the top of the mold and heated again to form the mold.

 At this time, the temperature during reheating for molding after the fusion process of the wig base sheet is preferably performed at a temperature lower than the melting point of the shell portion.

For example, when the shell portion is a polyester fiber having a low melting point, the temperature during reheating may be performed at 140 to 150 ° C.

The mold used in such a molding operation may be in the form of a full wig base or in the form of a partial wig base.

Subsequently, the fusion base is dried and cured, and the shape of the shaped wig base is firmly fixed. Unlike the conventional wig base which is stretched by heat, the wig base according to the present invention melts only a shell part having a low melting point, thereby providing a core part. By pulling the wig base does not stretch well and does not easily form deformation.

In addition, when the wig base manufactured using a fusion splicer is heated to a temperature higher than the melting point of the shell portion as described above, the shell portion in the hardened state is melted, thereby changing the shape of the wig base. It is possible to change the shape as much as heating to a temperature lower than the melting point of the core portion.

For example, if the melting point of the shell portion is 180 ° C., when the shell portion is heated to a temperature higher than that, the cross section of the warp and weft yarns are fused together while the shell portion is melted. As it becomes soft and restored to its original state, it can be molded into a desired shape. Accordingly, it can be changed according to the shape of the user's head or full / partial wig.

As described above, the wig base manufactured through a series of processes may be subjected to subsequent work such as hair dressing, curling, and dyeing after knotting as in the known art.
