Description

[[Technical Field]]

[0001] Reference to Related Application The present application claims priority from British Patent Application No. 2502852.3 filed on February 27, 2025, the entire content of which is incorporated herein by reference.

[0002] The present invention relates to a wig and a method for manufacturing the same. [[Background Art]]

[0003] There are various wigs. Some users wear wigs for aesthetic reasons to achieve different hair appearances. Other users wear wigs for medical reasons to avoid standing out in an undesirable way. Regardless of the underlying reason, wearing a wig is an important part of daily life for many users.

[0004] There are various wigs on the market that strive to meet the different needs of users. Most of these wigs strive to achieve the result of providing a desired or natural appearance when the wig is used. However, few, if any, wigs on the market strive to provide physiological health benefits to the wearer of the wig. [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0005] The present invention strives to address the above problem, or at least provide an alternative for people. [[Means for Solving the Problem]]

[0006] According to a first aspect of the present invention, a wig is provided comprising: i) a top cap including a fabric layer defining an outward-facing surface and an inward-facing surface; and ii) a plurality of hairs extending from the outward-facing surface of the fabric layer of the top cap, wherein the fabric layer of the top cap is made of a monofilament nylon fabric embedded with far-infrared emitting nanoparticles of calcium carbonate (with wavelengths in the range of 8-12 μm), the monofilament nylon fabric having 3.6-4.4 wt% of nanoparticles, and the nanoparticles having a diameter of 270-330 nm. In one embodiment, the monofilament nylon fabric may have 4.0 wt% of nanoparticles. Research leading to the present invention has shown that by using a wig incorporating such nanoparticles, it may be possible to provide many health benefits, including improved blood circulation, and the user's scalp may be able to receive a certain amount of far-infrared waves without impairing the structure of the wig or comfort during contact.

[0007] In one embodiment, the wig may include a back cap and side caps, each having only one fabric layer from which multiple hairs extend. The top cap, back cap, and side caps are connected to each other, for example, by sewing, to form a full cap.

[0008] Preferably, the back cap and side caps can be made from a material selected from the group of polyester and spandex. In one embodiment, the back cap and side caps can be made stretchable so as to conform to different scalp contours and / or be adjustable during slight movement of the scalp while being worn.

[0009] In some embodiments, the wig may not have a back cap or side caps. In such embodiments, the wig is a top-piece wig for covering the top of the user's scalp, regardless of whether the top cap can have one or more taps surrounding the fabric layer of the top cap.

[0010] In some embodiments, the wig may consist only of a top cap. In such embodiments, the wig is a top-piece wig for covering the top of the user's scalp.

[0011] A wig is provided, comprising a top cap having a fabric layer defining an outward-facing surface from which a plurality of hairs extend, and an inward-facing surface for engaging with or otherwise facing the user's scalp, wherein the fabric layer of the top cap, having a plurality of hairs extending from a first layer, is embedded with nanoparticles that emit far-infrared rays in the wavelength range of 8 to 12 μm.

[0012] Preferably, the top cap can be made from monofilament.

[0013] Preferably, the top cap fabric layer can be made from a material selected from nylon and polyester.

[0014] In one preferred embodiment, the fabric layer of the top cap can be made of nylon. The use of nylon is preferred because a fabric layer made of nylon, when the nanoparticles according to the present invention are added, can maintain its structural desirability for a wig and can also emit appropriate far-infrared waves in the context of the present invention.

[0015] Advantageously, the nanoparticles can be calcium carbonate. Calcium carbonate is advantageous because, when incorporated into the fabric layer of the top cap, it does not negatively affect structural desirability (e.g., durability or tactile comfort) and can provide the user with the benefits of far-infrared waves.

[0016] Preferably, the fabric layer of the top cap can consist of 3.6-4.4 wt% or 4.0 wt% nanoparticles. This percentage of nanoparticles is desirable because, as the research that led to this invention has found, it can produce sufficient far-infrared wave effects without impairing the material properties of the top cap and without causing adverse health effects.

[0017] In one embodiment, the nanoparticles can have a diameter of 270–330 nm or substantially 300 nm. This nanoparticle diameter was found to be appropriate in that it does not impair the material properties of the top cap.

[0018] In embodiments where the wig does not have a back cap or side caps, the wig is in the form of a wig consisting only of a top piece.

[0019] In embodiments where the wig includes a back cap and side caps (each having only one layer from which multiple hairs extend), the wig is a full wig.

[0020] A third aspect of the present invention provides a method for manufacturing a wig as described above (for example, according to the first aspect), the method comprising a series of steps: i) preparing a nylon salt; ii) preparing a solution from the nylon salt to form a nylon salt solution; iii) adding and mixing far-infrared emitting nanoparticles to the nylon salt solution so that the far-infrared emitting nanoparticles are evenly dispersed therein; iv) polymerizing the nylon salt solution containing the far-infrared emitting nanoparticles to form a polymerization solution; v) extruding the polymerization solution to form far-infrared embedded nanoparticle nylon filaments; and vi) processing the nylon filaments into a monofilament nylon fabric.

[0021] In a preferred embodiment, the method may comprise the steps of: x) forming far-infrared embedded nanoparticle nylon filaments into far-infrared embedded nanoparticle nylon yarns, and / or xi) weaving far-infrared embedded nanoparticle nylon yarns into a layer of far-infrared embedded nanoparticle fabric.

[0022] The far-infrared embedded nanoparticle fabric can be cut and shaped to form a fabric layer of a top cap.

[0023] Some embodiments of the present invention will now be described with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF EMBODIMENTS

[0025] The present invention relates to a wig, and will be described below as an example.

[0026] The wig according to the present invention includes both i) a wig consisting only of a top piece and ii) a full wig having a top piece (partial), side pieces (partial), and back piece (partial). A top piece wig covers only the top of the user's head. A full wig is a wig that covers the top, sides, and back of the user's head.

[0027] Figure 1 shows a user wearing a wig according to the first embodiment of the present invention. The wig is generally designated as 2. From the outside, it is shown that the wig has an externally facing hair portion 4. The hair portion 4 covers the structure of the wig 2 below it.

[0028] Figure 2 corresponds to Figure 1. However, Figure 2 also schematically shows the top cap 6 and the right side cap 8 (as seen from the wearer's perspective) below the hair section 4. The wig 2 includes a base structure made up of the top cap 6, the right side cap 8, the left side cap, and the back cap.

[0029] Figure 3 corresponds to Figures 1 and 2, but the hair portion 4 has been removed for ease of illustration. Figure 3 shows the top cap 6 that is placed on the user's head when in use. The top cap 6 is made of a monofilament material in the form of a mesh that covers the top and crown area of ​​the user's head. The right side cap 8 is placed on the right side of the user's head (as seen from the user's perspective). In this embodiment, the right side cap 8 has an ear tap 8a extending from it. The right side cap 8 and ear tap 8a are placed together above the user's right ear. The wig 2 also provides a left side cap 10 (and left ear tap 10a) having a mirror-image contour of the right side cap 8. The wig 2 has a back cap 12. In this embodiment, the top cap 6, side caps 8, 10 and back cap 12 are connected to each other to form a full cap that contacts and conforms to the shape of the user's head. The top cap 6, side caps 8, 10 and back cap 12 are connected to each other (e.g., sewn) to form a full cap.

[0030] Figures 4A and 4B show the wig 2 in more detail. The back cap 12 and side caps 8, 10 are made of only one layer of fabric from which the hair extends, while the top cap 6 is different. In this embodiment, the top cap 6 is made of one (first) mesh layer or fabric layer. This fabric layer of the top cap 6 has an outward-facing surface from which multiple artificial hairs extend when in use. The hair from the top cap 6, as well as the hair from the side caps 8, 10 and back cap 12, forms the hair portion 4. The top cap 6 also defines an inward-facing surface that engages with the user's scalp in this embodiment. In this embodiment, the top cap 6 is provided with one mesh layer. (In other embodiments, the top cap may have an additional (or second) mesh layer underneath, which is placed between the first and second mesh layers to add further comfort.)

[0031] Figures 5A and 5B show that the top cap 6 of wig 2 is substantial in size to cover the entire upper surface of the user's scalp.

[0032] Figure 6 shows a wig in an inverted configuration, meaning the wig is inside out. Due to the presence of the inner layer of the top cap, when inverted, the base portion of the hair is not visible from the inner layer.

[0033] As described above, the top cap 6 contains only one mesh fabric layer. The mesh fabric layer is made from nylon yarn 14 woven into the fabric that forms this layer. However, the nylon fabric is formed with an additive called far-infrared radiating nanoparticles. Details of how the nylon fabric is made will be described below.

[0034] In this embodiment, the fabric layer is essentially nylon, but with additives. Preparation of the nylon fabric layer of top cap 6 begins with the preparation of a nylon salt. The nylon salt is then formed into a nylon salt solution. Far-infrared radiating nanoparticles are added to the nylon salt solution and mixed so that they are evenly dispersed in the nylon salt solution. In this embodiment, the far-infrared radiating nanoparticles used are calcium carbonate (CaCO3), and the size of the far-infrared radiating nanoparticles is in the range of 270-330 nm. Experiments leading to the present invention have shown that the nylon salt solution should contain 3.6-4.4 wt% or substantially 4.0 wt% of nanoparticles. After mixing, the nylon salt solution with far-infrared radiating nanoparticles undergoes polymerization to form a polymerized solution. After polymerization, the solution is extruded through a nozzle or column. The polymerized solution is cooled as it is extruded to form nylon filaments with far-infrared radiating nanoparticles.

[0035] When forming nylon filaments, they can then be texturized, resulting in nylon yarn with remaining far-infrared emitting nanoparticles. The nylon yarn is then woven into a layer of far-infrared embedded nanoparticle nylon fabric. The far-infrared embedded nanoparticle fabric is then cut and shaped to form a second layer of top cap.

[0036] Experiments conducted have shown that the use of far-infrared nanoparticles for the second layer of the top cap allows the second fabric layer 6b to maintain sufficient contact comfort for the user's scalp without compromising the functionality of a normal wig, as demonstrated by the invention. Importantly, because the second layer of the top that engages with the user's scalp is in constant contact with it, the presence of far-infrared embedded nanoparticles allows the inner fabric layer to emit far-infrared rays (wavelengths generally in the range of 8-12 μm) that promote blood circulation, skin texture, and wrinkle reduction by increasing collagen and elastin in the dermis. However, the amount and size of the far-infrared embedded nanoparticles play a crucial role, as an excessive amount in the fabric could not only negatively affect the integrity or durability of the wig in which the inner fabric layer is formed, but could also harm the user's scalp.

[0037] In the embodiments described above, nylon is used as the material for the second layer, but experiments have shown that, in the context of the present invention, only a limited number of other materials can also be used. For example, polyester is an alternative.

[0038] For clarity, it should be understood that some features of the present invention, described in the content of separate embodiments, may be provided in combination or in a single embodiment. Conversely, for brevity, various features of the present invention, described in the content of a single embodiment, may be provided separately or in any suitable partial combination. It should be noted that some features of the embodiments are described by non-limiting examples. For example, in other embodiments, the top cap may have an additional (or second) mesh layer underneath, which is placed between the first and second mesh layers to further add comfort. Also, those skilled in the art will recognize prior art that has not been described above for the sake of brevity. For example, those skilled in the art are assumed to have knowledge of the production of conventional nylon or polyester fabrics, as well as the requirements for tactile comfort, durability and safety relating to clothing or wig materials. Those skilled in the art are also assumed to have knowledge of other features of wigs. For example, a lace front may be provided on the top cap to create or improve a natural-looking hairline.
