[Figure 4] 1 is a flowchart showing a method for manufacturing a glove according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] A glove and a method for manufacturing the same according to one embodiment of the present invention will be described below with reference to the drawings. In the following description of the embodiment, the same or corresponding parts in the drawings will be denoted by the same reference numerals, and description thereof will not be repeated.

[0018] 1 is a front view showing the configuration of a glove according to one embodiment of the present invention. Glove 1 according to one embodiment of the present invention is used, for example, to prevent a patient with atopic dermatitis from scratching their skin.

[0019] As shown in FIG. 1, a glove 1 according to one embodiment of the present invention includes a fibrous body portion 10, a covering portion 20, and a belt portion 30.

[0020] The fibrous body 10 is configured to be able to accommodate a hand. The fibrous body 10 in this embodiment is able to accommodate the entire hand.

[0021] The fibrous body 10 may be made of woven fabric, knitted fabric, or nonwoven fabric. The fibrous body 10 may be made of, for example, cotton. In this embodiment, the fibrous body 10 is made of 100% cotton, but is not limited to this composition. The fibrous body 10 may be made of any material that does not adversely affect the skin, and may be made of, for example, 85% cotton and 15% rayon.

[0022] The fibrous body 10 includes a tip portion 100 that covers at least the fingertips. In this embodiment, the tip portion 100 covers the entirety of each of the five fingers.

[0023] The covering portion 20 covers the tip portion 100. Specifically, the covering portion 20 covers the tip portion 100 up to a position corresponding to the first joint of the finger.

[0024] The covering portion 20 is made of rubber. By making the covering portion 20 from rubber, the covering portion 20 has better oxygen permeability than when made of synthetic resin, and therefore the covering portion 20 has excellent breathability.

[0025] The covering portion 20 in this embodiment is made of, for example, nitrile rubber. Note that the covering portion 20 is not limited to nitrile rubber, and may be made of natural rubber, isoprene rubber, butadiene rubber, or the like.

[0026] Generally, when manufacturing rubber, a vulcanization accelerator may be added to the rubber to shorten the vulcanization time. Examples of vulcanization accelerators include sulfenamide-based and thiuram-based vulcanization accelerators. The covering portion 20 in this embodiment does not contain a vulcanization accelerator. However, the covering portion 20 may contain a vulcanization accelerator as long as it has little effect on the allergic reaction of the human body caused by the vulcanization accelerator.

[0027] The belt part 30 is disposed at the wrist part of the fibrous body part 10. The belt part 30 is, for example, a hook-and-loop fastener such as Velcro (registered trademark). By fastening the belt part 30, the glove 1 can be fixed to the wrist, and the glove 1 is less likely to come off the hand.

[0028] Fig. 2 is an enlarged cross-sectional view of a fingertip of a glove according to one embodiment of the present invention, and Fig. 3 is an enlarged cross-sectional view of part III in Fig. 2 to show the structure of the glove.

[0029] 2 and 3, the covering portion 20 includes a substrate 110 and a hardening layer 140. The substrate 110 includes a first substrate layer 120 and a second substrate layer .

[0030] The substrate 110 is attached to the fibrous body 10. Specifically, in the substrate 110, the first substrate layer 120 is attached to the fibrous body 10 together with a portion of the second substrate layer 130.

[0031] The first substrate layer 120 has a first end 121. The first end 121 is located on the base side of the finger 2. The first substrate layer 120 is attached to the fibrous body 10 from the fingertip to the first end 121.

[0032] The first substrate layer 120 has protrusions 122 formed thereon. A plurality of protrusions 122 are formed irregularly toward the outer surface of the covering portion 20. Parts of the first substrate layer 120 penetrate between fibers (not shown) in the tip portion 100 toward the inner surface of the tip portion 100, thereby forming irregularities on the outer surface of the first substrate layer 120. As a result, the protrusions 122 are formed on the outer surface of the first substrate layer 120.

[0033] The second substrate layer 130 covers the first substrate layer 120. The second substrate layer 130 is interposed between the first substrate layer 120 and the hardened layer 140. The second substrate layer 130 covers the first substrate layer 120 so as to level the protrusions 122. The second substrate layer 130 has a flat outer surface.

[0034] The second substrate layer 130 has an extension 131. At the end of the covering portion 20 located on the base side of the finger 2, the extension 131 as part of the second substrate layer 130 extends from above the first substrate layer 120 and is attached to the fibrous body 10.

[0035] The covering portion 20 has a second end portion 141. The second end portion 141 is located closer to the base of the finger 2 than the first end portion 121. The second end portion 141 is located at a distance L from the first end portion 121. The extending portion 131 is attached to the fibrous body portion 10 together with a part of the hardened layer 140 between the first end portion 121 and the second end portion 141. The distance L from the first end portion 121 is preferably, for example, 0.5 mm or more and 1.5 mm or less, and more preferably 0.8 mm or more and 1.2 mm or less.

[0036] If the covering portion 20 were made up of only the first base layer 120 and the first end 121 of the first base layer 120 were angular, there is a possibility that the first end 121 would catch on the skin.

[0037] In this embodiment, a part of the extending portion 131 of the second substrate layer 130 adheres to the fibrous body 10 while following the first end portion 121. This allows the end portion of the second substrate layer 130 to be smoothly connected to the fibrous body 10 while gently inclining. As a result, it is possible to prevent the end portion of the covering portion 20 from getting caught on the skin.

[0038] The hardening layer 140 is located on the outer surface of the covering portion 20. The hardening layer 140 in this embodiment covers the outer surface of the second substrate layer .

[0039] The hardened layer 140 is formed by hardening a portion of the base 110. Specifically, the hardened layer 140 is formed by hardening the outer surface of the base 110 by a chlorine treatment, which will be described later. By forming the hardened layer 140 on the outer surface of the covering portion 20, the outer surface of the covering portion 20 has reduced friction resistance compared to the base 110.

[0040] The thickness t of the covering part 20 is, for example, preferably 0.2 mm or more and 0.6 mm or less, and more preferably 0.3 mm or more and 0.5 mm or less. By making the covering part 20 have the above thickness, it is possible to operate electronic devices that can be operated by a touch panel while wearing the glove 1.

[0041] The covering portion 20 does not extend to the inner surface of the fibrous body portion 10. Specifically, the base body 110 does not extend to the finger 2 side of the fibrous body portion 10.

[0042] In this embodiment, the base 110 is configured from two layers, the first base layer 120 and the second base layer 130, but is not limited to this configuration. The base 110 may be configured from three or more layers, or may be configured from a single layer if the protrusions 122 are not formed.

[0043] A method for manufacturing a glove according to one embodiment of the present invention will now be described with reference to Fig. 4. Fig. 4 is a flow chart showing a method for manufacturing a glove according to one embodiment of the present invention.

[0044] As shown in FIG. 4, in a method for manufacturing a glove according to one embodiment of the present invention, first, a fibrous body 10 configured to accommodate a hand and including a tip portion 100 covering at least the fingertips is prepared (step S1).

[0045] Next, the tip portion 100 is coated with rubber to form the coating portion 20. Specifically, the process of forming the coating portion 20 includes a process of attaching rubber to the fibrous body portion 10 to form the base body 110, and a process of hardening a part of the base body 110 to form the hardened layer 140 located on the outer surface of the coating portion 20 (process S4).

[0046] Furthermore, the process of attaching rubber to the fibrous body 10 to form the base 110 includes a process of attaching rubber to the fibrous body 10 to form a first base layer 120 (process S2), and a process of attaching rubber to cover the first base layer 120 to form a second base layer 130 (process S3).

[0047] In the step of adhering rubber to the fibrous body 10 to form the first base layer 120 (step S2), the glove 1 is attached to a jig having the same shape as a hand, and then the tip portion 100 is immersed in a tank filled with rubber to adhere the first base layer 120 to the tip portion 100. Thereafter, the first base layer 120 is dried to fix the first base layer 120 to the tip portion 100.

[0048] Next, in the step of forming the second substrate layer 130 (step S3), rubber is attached so that an extension portion 131 as part of the second substrate layer 130 at the end of the covering portion 20 located on the base side of the finger 2 extends from above the first substrate layer 120 and adheres to the fibrous body 10. Specifically, similar to the first substrate layer 120, the tip portion 100 is immersed in a bath filled with rubber, so that the second substrate layer 130 is attached to the tip portion 100 while covering the first substrate layer 120. Thereafter, the second substrate layer 130 is dried, and the second substrate layer 130 is fixed to the first substrate layer 120 and the tip portion 100.

[0049] Next, in the step of forming the hardened layer 140 (step S4), a portion of the base 110 is halogen-treated. In this embodiment, the outer surface of the base 110 is chlorine-treated. Specifically, the glove 1 is entirely immersed in a bath filled with chlorine liquid to chlorine-treat the base 110. As a result, a hardened layer 140 is formed on the outer surface of the covering portion 20, where a portion of the base 110 is hardened. Note that, in this embodiment, chlorine treatment is performed as a method for forming the hardened layer 140 on the outer surface of the covering portion 20, but the hardened layer 140 may also be formed on the outer surface of the covering portion 20 by other methods, such as electron beam graft polymerization.

[0050] In a glove 1 and a manufacturing method thereof according to one embodiment of the present invention, a covering portion 20 covering the tip portion 100 of a fibrous body portion 10 has a hardened layer 140 located on the outer surface of the covering portion 20, the hardened layer 140 being a part of the base 110 that is hardened. This reduces the frictional resistance of the hardened layer 140 compared to the base 110, making the hardened layer 140 less likely to catch on the skin, thereby preventing the fingertips from scratching the skin through the covering portion 20.

[0051] In the glove 1 and its manufacturing method according to one embodiment of the present invention, the base 110 includes the first base layer 120 and the second base layer 130, and therefore the convex portions 122 of the first base layer 120 can be covered by the second base layer 130, and therefore the outer surface of the covering portion 20 can be made smooth.

[0052] In a glove 1 and a manufacturing method thereof according to one embodiment of the present invention, at the end of the covering portion 20 located on the base side of the finger 2, the extension portion 131 of the second base layer 130 extends from above the first base layer 120 and is attached to the fibrous body portion 10, thereby preventing a step from occurring at the boundary between the fibrous body portion 10 and the covering portion 20, thereby preventing the end of the covering portion 20 from scratching the skin.

[0053] In the glove 1 according to one embodiment of the present invention, the covering portion 20 does not extend to the inner surface of the fibrous body portion 10, and therefore the covering portion 20 is not positioned on the inner surface of the glove 1, thereby suppressing discomfort caused by the covering portion 20 coming into contact with the skin when the glove 1 is worn.

[0054] In the glove 1 according to one embodiment of the present invention, the fibrous body portion 10 is made of cotton, which does not have an adverse effect on the skin and can improve the comfort of wearing the glove 1.

[0055] In the glove 1 according to one embodiment of the present invention, the covering part 20 does not contain a vulcanization accelerator, and therefore, the occurrence of allergic symptoms due to wearing the glove 1 can be suppressed.

[0056] In the glove 1 and its manufacturing method according to one embodiment of the present invention, in the step of forming the hardened layer 140 on the outer surface of the covering portion 20, the hardened layer 140 can be easily formed by treating a part of the base body 110 with a halogen.

[0057] Although glove 1 in one embodiment of the present invention has a configuration in which each of five fingers is covered by one of five tip parts, the present invention is not limited to this configuration and may have a configuration in which all five fingers are covered by one tip part. Also, glove 1 in one embodiment of the present invention is not limited in size and can be widely used for sizes from adults to children.

[0058] It should be noted that the above-described embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present disclosure should not be interpreted solely by the above-described embodiments. Furthermore, all modifications within the meaning and scope of the claims are included.
