DETAILED DESCRIPTION OF THE INVENTION

[0023] Overview The first embodiment, the second embodiment, and several modified examples will be described below in this order. The invention described in these embodiments mainly relates to a method for manufacturing clothing. Here, clothing refers to a tangible object worn on any part of the body of a human (or non-human animal). Non-human animals include, for example, pet animals such as dogs and cats. Any part of the body refers to the torso, legs, arms, neck, head, etc. Clothing refers to objects to be worn, such as clothes, underwear, socks, shoes, gloves, scarves, masks, wristbands, leg bands, and hats.

[0024] First Embodiment In the first embodiment, a wristband 10 (see FIGS. 1A and 1B) will be described as an example of clothing. The following describes, in this order: (1) the configuration and function of the wristband 10, (2) a method for manufacturing the wristband 10, and (3) its effects.

[0025] <Wristband configuration and functions> FIG. 1A is a front view of a wristband 10 according to this embodiment, and FIG. 1B is a rear view of the wristband 10. FIG. Wristband 10 includes sheet material 12 (an example of fabric), hook-and-loop fastener 14, and pattern body 16 (an example of a solid film). The wristband 10 has the function of making it easier to break up clumps of red blood cells in the blood vessels of the human body compared to when the wristband 10 is not worn by the user, i.e., when it is not attached to the user's wrist.

[0026] [Sheet material and hook-and-loop fastener] 1A and 1B, the sheet material 12 is, for example, a long elastic sheet, that is, the sheet material 12 has stretchability. As shown in FIG. 1A, a loop 14A of a hook-and-loop fastener 14 is attached to one end of a surface 12A of the sheet material 12 in the longitudinal direction. At one end portion in the longitudinal direction of the back surface 12B (an example of one surface) of the sheet material 12, a hook 14B of a hook-and-loop fastener 14 is attached which is detachable from the loop 14A. The wristband 10 is used by bringing the back surface 12B into contact with the user's wrist. The wristband 10 is designed to be stretched by 5% or more from its natural length when in use.

[0027] [Pattern body] 1B, the pattern body 16 is attached to the rear surface 12B of the sheet material 12. Therefore, the pattern body 16 comes into contact with the wrist of the user when the user uses (wears) the device. As an example, the pattern body 16 is composed of an aggregate of multiple regular hexagons arranged in a honeycomb pattern. However, each component of the pattern body 16 does not have to have the shape of the first embodiment, and may be, for example, a polygon other than a regular hexagon, a circle, a combination of these, or another shape. Furthermore, each component of the pattern body 16 may be an aggregate of different attachments. The ratio (area ratio) of the area of ​​the portion where the pattern body 16 is applied to the area of ​​the back surface 12B is designed to be, for example, 20% or more and 90% or less. The coating thickness of the pattern body 16 is set to, for example, 10 μm or more and 800 μm or less.

[0028] The pattern body 16 contains a binder resin and silicon dioxide powder. The silicon dioxide powder has an average particle size of, for example, 10 μm or less. The silicon dioxide powder is dispersed in a binder resin and forms part of the pattern body 16.

[0029] The binder resin is, for example, a mixed resin in which titanium oxide is left in an acrylic resin. The binder resin has the function of adhering the pattern body 16, in which silicon dioxide powder is dispersed, to the sheet material 12, and the function of expanding and contracting in accordance with the expansion and contraction of the sheet material 12. The binder resin does not have to be a mixed resin as long as it can exhibit the above functions.

[0030] Although the pattern body 16 is described as containing a binder resin and silicon dioxide powder, the powder may contain powders other than silicon dioxide powder. For example, powders of metal oxides such as iron trioxide, feldspar, and quicklime, or alumina may be included.

[0031] The above is a description of the configuration and functions of the wristband 10 of the first embodiment.

[0032] <Wristband manufacturing method> Next, a method for manufacturing the wristband 10 of the first embodiment will be described with reference to FIGS. 2A to 2E. 2A to 2E are flow diagrams of a manufacturing method for wristband 10 according to the first embodiment. Also, FIGS. 2A to 2E respectively show a first method F10A, a second method F10B, a third method F10C, a fourth method F10D, and a fifth method F10E. Of these methods, first method F10A is the basic method, while second method F10B, third method F10C, fourth method F10D, and fifth method F10E are improved methods that add additional steps to the basic method. All of these methods fall within the technical scope of the present invention. Each method will be explained below.

[0033] [First method] The first method F10A includes steps S10, S20, S30, and S40, as shown in FIG. 2A, and is executed in the order listed.

[0034] (S10) S10 is a step (preparation step) of preparing a mixed fluid. The mixed fluid is (1) a powder dispersion liquid consisting of water (an example of a liquid), silicon dioxide powder with an average particle size of 10 μm or less, and a polymer material, and (2) a binder resin, which are stirred using a stirrer (not shown). Examples of the polymeric material include carboxylate-type polymeric surfactants, sodium hexametaphosphate, danyutan gum, and isothiazolone chloride solution. The composition ratio of the powder dispersion, i.e., the weight percentage ratio of water (an example of a liquid), polymer material, and silicon dioxide powder having an average particle size of 10 μm or less, is, for example, 25% or more and less than 35%, 1% or more and less than 10%, and 55% or more and less than 74%. Furthermore, the mixed fluid is (1) a powder dispersion liquid that satisfies the above-mentioned conditions and (2) a binder resin, and the weight percentage ratio of (1) the powder dispersion liquid that satisfies the above-mentioned conditions to (2) the binder resin is 1% or more and less than 10%:90% or more and less than 99%, and is stirred by a stirrer (not shown). The viscosity of the mixed fluid is, for example, 20 Pa·s or more and 80 Pa·s or less.

[0035] (S20) S20 is a step of attaching the mixed fluid to the rear surface 12B of the sheet material 12 as a fluid film (attaching step). In the adhering step S20, the mixed fluid prepared in the preparing step S10 is adhered to the rear surface 12B of the sheet material 12 as a fluid film by, for example, screen printing. Note that the method for depositing the fluid film in the depositing step S20 is not limited to screen printing, as long as it can deposit the fluid film. For example, inkjet printing or a transfer method such as offset printing may also be used.

[0036] (S30) S30 is a process (irradiation process) in which terahertz waves (terahertz light) emitted from a resonant tunneling diode device (not shown) as an example of an oscillation source are irradiated onto the fluid film attached to the rear surface 12B of the sheet material 12 for a predetermined period of time or more. The specified time is, for example, 20 seconds. The frequency of the terahertz waves irradiated onto the fluid film is 0.1 to 10 terahertz (THz). The wavelength of the terahertz waves irradiated onto the fluid film is 30 μm to 3 mm. The terahertz waves irradiated onto the fluid film are, for example, incoherent electromagnetic waves (light) that satisfy these conditions.

[0037] (S40) S40 is a step of removing the liquid from the fluid film and then fixing the solid film formed as a result of removing the liquid from the fluid film to the rear surface 12B of the sheet material 12 (fixing step). In the fixing step S40, the liquid is evaporated from the fluid film using a dryer (not shown), and the remaining solid pattern (solid film) is fixed to the rear surface 12B. As long as the liquid can be removed from the fluid film, the method for removing the liquid in the fixing step S40 is not limited to drying with a dryer. For example, the liquid may be removed by dehumidifying (evaporating) it with a dehumidifier (not shown) or a heater (not shown). Then, when a solid film is formed on the rear surface 12B of the sheet material 12, the first method F10A is completed. This concludes the description of the first method F10A.

[0038] [Second method] Next, the second method F10B will be described with reference to FIG. 2B. The second method F10B executes S35B between S30 and S40 in the first method F10A (FIG. 2A). The second method F10B differs from the first method F10A only in this respect.

[0039] (S35B) S35B is a process (leaving process) in which the fluid film (an example of an attached portion) attached to the rear surface 12B of the sheet material 12 by the attachment process S20 is left in an environment with the same temperature and humidity as the irradiation process S30 for a period of at least 300 seconds. The leaving step S35B is completed by leaving the attached portion for 300 seconds or more from the end of the irradiation step S30 in the same environment as in the irradiation step S30, for example. This concludes the description of the second method F10B.

[0040] [3rd method] Next, a third method F10C will be described with reference to FIG. 2C. The third method F10C executes S30C instead of S30 in the first method F10A (FIG. 2A). The third method F10C differs from the first method F10A only in this respect.

[0041] (S30C) S30C is a step of irradiating the fluid film attached to the rear surface 12B of the sheet material 12 with terahertz waves while applying tension to the fluid film (deformation irradiation step). The deformation irradiation process S30C is completed by, for example, fixing one longitudinal end of the sheet material 12 while pulling the other end, maintaining the sheet material 12 in a state stretched by 5% of its natural length in the longitudinal direction for a predetermined time (for example, 20 seconds) equivalent to that in S30, and then irradiating terahertz waves. This concludes the explanation of the third method F10C.

[0042] [4th method] Next, a fourth method F10D will be described with reference to FIG. 2D. The fourth method F10D executes the leaving step S35B of the second method F10B between steps S30C and S40 of the third method F10C (FIG. 2C). The fourth method F10D differs from the third method F10C only in this respect. This concludes the description of the fourth method F10D.

[0043] [Fifth method] Next, a fifth method F10E will be described with reference to FIG. 2E. The fifth method F10E executes S35E (deformation and leaving step) instead of S35B in the fourth method F10D (FIG. 2D). The fifth method F10E differs from the fourth method F10D only in this respect.

[0044] (S35E) The deformation leaving process S35E is completed by leaving the sheet material 12 in a state stretched by 5% of its natural length in the longitudinal direction for a predetermined time (for example, 300 seconds) or more from the end of the deformation irradiation process S30C. This concludes the description of the fifth method F10E.

[0045] The above is a description of the method for manufacturing the wristband 10 according to the first embodiment.

[0046] <Effects> Next, a description will be given of the effects of the first embodiment. The effects of the first embodiment are based on the following wristband evaluation test.

[0047] [Wristband evaluation test] In the wristband evaluation test, the following tests and evaluations were conducted. First, we measured the blood flow velocity in the capillaries of the fingers of 10 subjects before and after wearing the prototype wristband samples. The test subjects wore the samples for 90 seconds. Furthermore, microscopic photographs of blood collected from the veins of the finger before and after the wristband samples were worn were observed.

[0048] (Table in Figure 3) The table in FIG. 3 lists a number of wristband samples of the first embodiment (wristband samples 01 to 10) and wristband samples of the first comparative embodiment (wristband samples 11 to 21), along with their respective measurement results.

[0049] (Micrographs in Figures 4A to 4C) The micrographs in FIGS. 4A to 4C are micrographs of red blood cells in blood vessels of subjects A to C before and after wearing the wristband sample of the first embodiment, respectively.

[0050] Here, we will provide some additional information about the table in Figure 3.

[0051] (Wristband samples 01-10) Wristband samples 01 to 10 were each produced by one of the first to fifth methods in the method for producing wristband 10 according to the first embodiment. There are two types of preparation processes, Preparation A and Preparation B, and the difference between them is the composition of the mixed fluid. In Preparation A, the mixed fluid is a fluid obtained by stirring the aforementioned powder dispersion and binder resin. In contrast, in Preparation B, the mixed fluid is a fluid obtained by stirring a mixture of the granules of Preparation A with metal oxides including diferric oxide, feldspar, and quicklime, and alumina, at a weight ratio of 3% of the total. The tensions described in the irradiation step and the leaving step are as described above (at 5% elongation). The average increase rate of the measurement results was calculated by measuring the blood flow velocity (V1) in the capillaries of the fingers of each of the 10 subjects before they wore several prototype wristband samples (wristband samples 01 to 21), and the blood flow velocity (V2) in the capillaries of the fingers after they wore the samples, and then calculating (V2-V1) / V1 x 100% and averaging the results.

[0052] (Wristband samples 11-21) Wristband samples 11 to 21 were each prototyped using a method other than the manufacturing method (first to fifth methods) for wristband 10 of the first embodiment. The manufacturing methods for wristband samples 11 to 21 have in common that they do not all include an irradiation step. The modified first method in the method name refers to a modification of the first method in which the irradiation method is not performed. Other modified methods are also similar to the modified first method. In contrast, the absence of a step in the method name (in the case of wristband sample 21) means that the sample was made of sheet material 12 to which only hook-and-loop fastener 14 was attached.

[0053] [Considerations based on the results of the wristband evaluation test] Next, based on the results of the wristband evaluation test, the features and effects derived by the inventors of the present application will be considered.

[0054] (First effect) Feature 1: After the attachment step S20 and before the fixing step S40, the irradiation step S30 or the deformation irradiation step S30C is performed.

[0055] As shown in the table of FIG. 3, wristband samples 01 to 10 of the first embodiment have a higher average increase rate than wristband samples 11 to 20 of the first comparative embodiment. The clear difference between wristband samples 01 to 10 of the first embodiment and wristband samples 11 to 20 of the first comparative embodiment is that the former were prototyped with feature 1 implemented, whereas the latter did not.

[0056] Considering the reason for this, by performing Feature 1, the powder contained in the mixed fluid that adheres to the sheet material 12 as a fluid (still containing the liquid (water)) in the adhering step S20 is irradiated with terahertz waves in the irradiation step S30. As a result, the liquid (water) absorbs the terahertz waves (obtains external energy) and vibrates. As a result, the powder and binder resin also vibrate. Furthermore, since the natural frequency of the powder (silicon dioxide) is in the terahertz band, it is thought that the silicon dioxide powder also absorbs the terahertz waves (obtains external energy) and vibrates. As a result of the above, it is thought that performing the irradiation step S30 makes it easier for the powder to be dispersed more finely and uniformly before the mixed fluid solidifies. In contrast, wristband samples 11 to 20 of the first comparative embodiment, which do not implement Feature 1, ie, do not implement irradiation step S30, should not have as high a powder dispersibility as wristband samples 01 to 10 of the first embodiment. As described above, wristband samples 01-10 of the first embodiment have more dispersed and adhered silicon dioxide powder than wristband samples 11-20 of the first comparative embodiment, and therefore are more likely to be affected by the powder (the effects of irradiating the human body with terahertz waves) when worn by a user. As a result, wristband samples 01-10 of the first embodiment have a higher average rate of increase than wristband samples 11-20 of the first comparative embodiment.

[0057] (Second effect) Feature 2: The viscosity of the mixed fluid used in the adhesion step S20 (prepared in the preparation step S10) is 20 Pa·s or more and 80 Pa·s or less.

[0058] Although not shown in the table of Figure 3, the following has been found from tests conducted by the inventors. When the viscosity of the mixed fluid is less than 20 Pa·s, the mixed fluid adhered to sheet material 12 (fabric) in adhesion step S20 will soak into the fabric, making it difficult to leave a fluid film on the surface during irradiation step S30, compared to when the viscosity is 20 Pa·s or higher. In contrast, when the viscosity of the mixed fluid is greater than 80 Pa·s, even when terahertz waves are irradiated in irradiation step S30, the measurement result will be lower than that of wristband samples 01 to 10 in the table in Figure 3 (however, it will be better or equivalent to that of wristband samples 11 to 20), compared to when the viscosity is 80 Pa·s or lower. For these reasons, feature 2 is preferred.

[0059] (Third effect) Feature 3: As in the deformation irradiation step S30C, the fluid film is irradiated with terahertz waves while applying tension to the adhesion portion of the sheet material 12 (fabric) to which the fluid film is attached.

[0060] As shown in the table in Figure 3, Wristband Sample 03 and Wristband Sample 05 implement Feature 3. Wristband sample 03 and wristband sample 05 were the top two out of wristband samples 01 to 05 with excellent evaluation results. Wristband sample 03 and wristband sample 05 were prototyped by carrying out a modified irradiation process S30C in which tension was added to the irradiation process S30, which is thought to make the effect described in the first effect above more likely to occur. For these reasons, feature 3 is preferred.

[0061] (Fourth effect) Feature 4: After the irradiation step S30 or the deformation irradiation step S30C and before the fixing step S40, the leaving step S35B is performed.

[0062] As shown in the table of FIG. 3, wristband sample 02 and wristband sample 04 implement feature 4. In particular, between wristband sample 01 and wristband sample 04, which differ only in the presence or absence of leaving step S35B, the latter, which performs leaving step S35B, has better evaluation results than the former, which does not. It is believed that in wristband sample 04, the silicon dioxide powder is more easily dispersed due to leaving step S35B compared to wristband sample 01, in which the fluid film is heated in fixing step S40 immediately after irradiation step S30. For these reasons, feature 4 is preferred.

[0063] (Fifth Effect) Feature 5: In the leaving step S35, the adhesion portion is left for a period of at least 300 seconds or more in an environment with the same temperature and humidity as in the deformation and irradiation step S30C, while being applied with the same tension as in the deformation and irradiation step S30C.

[0064] As shown in the table in Figure 3, wristband sample 05 implements feature 5. Of the wristband samples 01 to 05, wristband sample 05 had the best evaluation results. List band sample 05 is considered to be more likely to disperse the silicon dioxide powder by the deformation leaving process S35E than list band sample 02 in which the fluid film is heated up in the fixing process S40 immediately after the deformation irradiation process S30C. For such reasons, feature 5 is preferable. The above is the description of the effects of the first embodiment.

[0065] The above is the description of the first embodiment.

[0066] [[ID=~12]]≪Second Embodiment≫ [[ID=1~4]]Next, the second embodiment will be described. In the second embodiment, the T-shirt 20 (see FIG. 5) will be described as another example of clothing. Hereinafter, (1) the configuration and function of the T-shirt 20, (2) the manufacturing method of the T-shirt 20, and (3) its effects will be described in this order of description.

[0067] <Configuration and Function of T-shirt> [[ID=~23]] FIG. 5 is a rear view of the T-shirt 20 of the second embodiment. The T-shirt 20 includes a T-shirt body 22 (another example of fabric) and a pattern body 24 (another example of a solid film). The T-shirt 20 has a function of making it easier to break up the mass of red blood cells in the blood vessels of the human body compared to when it is not worn by the user.

[0068] The T-shirt body 22 is a commonly circulated one. That is, it is knitted with fibers of resins such as polyester, cotton fibers, or fibers combining these. As an example, the pattern body 24 is attached as two linear portions extending from the neck hole portion to the body hole portion near the center in the width direction on the back surface (another example of one side of the fabric) of the T-shirt body 22. And, as shown in the enlarged portion of FIG. 5, the two linear portions constitute a pattern as an example. The material, composition, etc. of the pattern body 24 conform to those of the pattern body 16 of the first embodiment.

[0069] [[ID=~37]] <Manufacturing Method of T-shirt> The manufacturing method of the T-shirt 20 of the second embodiment is similar to the manufacturing method of the wristband 10 of the first embodiment. In other words, it should be understood that the sheet material 12 of the first embodiment is replaced with a T-shirt body 22.

[0070] <Effects> Next, the effects of the second embodiment will be described. The effects of the second embodiment are based on the following T-shirt evaluation test.

[0071] [T-shirt evaluation test] The T-shirt evaluation test was basically similar to the wristband evaluation test described in the first embodiment, but differed from the first embodiment in that the T-shirt evaluation test measured the blood velocity in the blood vessels of the upper arm instead of the finger.

[0072] (Table in Figure 6) The table in FIG. 6 lists a number of T-shirt samples of the second embodiment (T-shirt samples 01 to 10) and T-shirt samples of the second comparative embodiment (T-shirt samples 11 to 21), along with their respective measurement results.

[0073] [Considerations based on the results of the T-shirt evaluation test] Next, based on the results of the T-shirt evaluation test, the characteristics and effects derived by the inventors of the present application will be considered.

[0074] It has been confirmed that the measurement results (average increase rate values) of the second embodiment tend to be lower than those of the first embodiment. However, the measurement results of the second embodiment confirm the same qualitative trends as those of the first embodiment (see the table in FIG. 3). That is, the first to fifth effects of the first embodiment described above are also confirmed in the case of the T-shirt 20. It should be noted that the average increase rate for T-shirt 20 is thought to be lower than that for wristband 10 because T-shirt 20 is not worn by being pressed against the user's body like wristband 10.

[0075] <<Multiple Modifications>> As described above, the first and second embodiments have been described as examples of the present invention, but the forms included in the technical scope of the present invention are not limited to these. For example, the pattern bodies 16 and 22 may be replaced with a coating film of the mixed fluid that constitutes the pattern bodies 16 and 22 . Furthermore, in the first and second embodiments described above, the manufacturing object is clothing, but it is also possible to consider that the manufacturing object does not have to be clothing as long as it is something that the user wears or touches. For example, instead of clothing, the manufacturing object may be an accessory such as glasses, a wristwatch, or earrings. Furthermore, the manufacturing object may be, for example, bedding (pillowcases, sheets, etc.), cushions, chair covers, etc. In view of the above, an example of the manufacturing object may be an article that comes into contact with the human body.
