(First embodiment of the present invention)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view of a worn state of the moisturizing supporter according to the present embodiment, and FIG. 2 is a schematic configuration perspective view of the moisturizing supporter according to the present embodiment.
In each of the drawings, the moisturizing supporter 1 according to the present embodiment is a thin supporter body 10 that is knitted as a substantially tubular body having elasticity and covers a part including the heel portion of the foot 50, and a heel of the supporter body 10. A non-moisture permeable sheet 20 that is integrally heated and pressed on the inside of the portion.
[0013]
The supporter body 10 is formed by using a nylon and polyurethane elastic yarn as a material, knitting it into a substantially cylindrical shape that is continuously continuous, and then sewing each open end as a rib portion 11 using a knitting method similar to a conventional sock. It is knitted, and is configured to cover the space from the middle part of the instep and arch to the ankle when worn. The rib portion 11 is knitted in such a manner that a stronger restoring force can be obtained even with the same amount of elongation as compared with other portions, and is configured to prevent slippage during wearing. The supporter body 10 may be made of cotton, silk, or other unburned fibers other than or in addition to nylon and polyurethane elastic materials.
[0014]
The moisture-impermeable sheet 20 is formed of a substantially sheet-like body mainly composed of a polyurethane resin, is overlapped on the heel portion of the supporter main body 10, and has a configuration in which the entire surface is integrally heat-pressed to the supporter main body 10. A chemical (a coating agent) in which a plurality of substances are mixed is applied to the surface of the moisture-impermeable sheet 20. The chemicals include a water solution of far-infrared radiation ceramics (silicon dioxide, aluminum oxide, magnesium oxide, etc.), a silk protein (fibroin) powder, a chitosan powder, etc. mixed at a predetermined ratio to form a uniform dispersion. Use agent.
[0015]
Next, the manufacturing process of the moisturizing supporter according to the present embodiment will be described. First, after knitting an integral substantially cylindrical body appropriately given the shape of the heel and the like as the supporter body 10, if appropriate end processing such as sewing each open end of the substantially cylindrical body is performed, The supporter body 10 is completed.

After the supporter main body 10 is obtained, the attachment of the moisture-impermeable sheet 20 to the supporter main body 10 is performed by first turning the supporter main body 10 with the inside surface turned upside down, particularly the heel portion, by putting the leg on the foot and stretching it. Forcibly stretch it up, down, left and right. A non-permeable sheet 20 cut into a predetermined shape is applied to the heel portion of the supporter body 10 on the supporter body 10 in the stretched state, and the non-permeable sheet 20 is heated and pressed to the supporter body 10 by a press device. And unite. In this way, in the heel portion, the entire surface of the moisture-impermeable sheet 20 is firmly integrated with the supporter main body 10 in a state in which it enters the knitted structure of the supporter main body 10, so that the supporter main body 10 does not easily separate even after undergoing deformation and expansion and contraction.
[0017]
Subsequently, a usage state of the moisturizing supporter according to the present embodiment will be described. Put the toe into the one end opening of the moisturizing supporter 1 and cover it over the foot 50 as it is, pull up the one end opening to the ankle part, and position the other end opening just around from the instep of the foot 50 to the arch. If the moisturizing supporter 1 is exactly fitted to the position where the foot 50 is to be worn, the supporter is put on. The moisture-impermeable sheet 20 is thin, and the feeling of wearing hardly changes as compared with ordinary supporters or socks without the moisture-impermeable sheet 20.
[0018]
In this state, each part of the supporter main body 10 fits and adheres to the foot 50, and the rib portion 11 holds the position of the opening of the supporter main body 10, so that even when the movement of the foot 50 becomes large such as when walking. In addition, the supporter body 10 does not significantly shift with respect to the foot 50, the positional relationship between the non-permeable sheet 20 and the heel does not change, and the escape of moisture from the skin of the heel portion is directly applied to the heel portion. The wet sheet 20 can surely prevent the heel portion from drying and can keep the skin moist.
[0019]
In addition, since the moisture-impermeable sheet 20 is located on the inner surface of the supporter main body 10, the moisture-retaining effect and the heat-retaining effect of the far-infrared-emitting ceramic component coated on the surface of the moisture-impermeable sheet 20 by far-infrared radiation, In addition to the humidity control effect due to the hygroscopicity, the antibacterial and deodorizing effects of the chitosan component, etc., a comfortable wearing feeling can be obtained on the heel together with the maintenance of moisture by moisturizing. On the other hand, the toe portion of the foot 50 is exposed to the outside of the supporter body 10, so that air permeability to each toe can be ensured. Even if the moisturizing supporter 1 is worn at bedtime, there is no discomfort of the foot 50, and Does not inhibit.
[0020]
From the wearing state of the moisturizing supporter 1, socks can be further layered on the outside as needed, and in this layering, the thin supporter body 10 does not protrude to the surface via the outer socks and has an external appearance. Does not impair. Furthermore, since the toes are not covered with the supporter main body 10, the toes can be prevented from being stuffy.
