Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shorts worn during menstruation of women.

[0002]

2. Description of the Related Art Most sanitary shorts of this type are usually made by simply sewing a waterproof cloth on the crotch portion, and have to deal with discomfort such as menstrual pain with an analgesic. I do not get it and I am worried about side effects.

[0003] In addition, when lying down, physiological discharge may leak from the crotch portion, which may contaminate the bedding.

[0004]

On the other hand, tourmaline is known as an ore that generates negative ions and emits far-infrared rays. Wearing a cloth mixed with fine powder of the fine powder has a therapeutic effect on stiff shoulders and joint pain. It is known.

However, it has been found that the amount of far-infrared radiation emitted by tourmaline itself is not so large, and that it cannot exert a remarkable therapeutic effect on menstrual pain, which is increased by cooling. In addition, since shorts are required to have good stretchability and softness of the fabric, it is difficult to form the shorts using only tourmaline-containing fibers, and it is necessary to use tourmaline-free fibers such as cotton. But the effect is limited.

Accordingly, an object of the present invention is to provide shorts having a high therapeutic effect on menstrual pain by further enhancing the radioactivity of far infrared rays using tourmaline-containing fibers.

[0007] Another object of the present invention is to provide shorts in which the discharge is prevented from leaking even when lying down.

[0008]

To solve the above-mentioned problems, a sanitary short according to the present invention comprises a front body and a crotch formed by a knitted fabric containing at least 10% by weight of a fiber containing tourmaline and a ceramic emitting far-infrared rays. And a back body, and a pad made of a nonwoven fabric containing tourmaline and a fiber containing far-infrared rays of 50% by weight or more is attached to a portion corresponding to the lower abdomen of the inner surface of the front body, and a waterproof cloth is applied to the inner surface of the crotch portion. This is because of the attached structure.

[0009] The fibers preferably contain about half the amounts of tourmaline and ceramic. Further, it is preferable to form an acrylic resin coating film on both sides of the pad. Further, it is preferable that the waterproof cloth of the crotch portion adheres to a height of 10 to 15 cm from the bottom of the front of the shorts so that the discharge does not leak.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a sanitary short according to the present invention comprises a draped front body 10, a crotch portion 20 and a back body 30, one edge 11 of the front body 10 having a reduced width, and a crotch portion. 20 are stitched together, the other end 22 of the crotch portion 20 is stitched to one end 31 of the back body 30 having a reduced width, and the front body 10 is further stitched.
Side edges 12 of the back body 30
When suturing with 2, 32, the outline of the shorts is completed. At this time, as shown in FIG. 2, a pad 40 is sewn on the inner surface of the front body 10 between the outer material 10a and the lining 10b. In addition, the outer surface 20a
, A breathable waterproof cloth 50 is sewn.

The completed shorts are shown in FIG. 4, FIG. 5, and FIG. As shown in the figure, an elastic waistband 1a having a large tensile stress is sewn over the entire circumference of the mouthpiece 1, and legs formed by inclined edges 13, 13, both side edges 23, 23, and inclined edges 33, 33. Decorative edges 2a, 2a such as laces are provided around the insertion holes 2, 2.

The outer fabric 10a and lining 10b of the front body 10 forming the above shorts, the outer fabric 20a of the crotch portion 20, and the back body 30 are usually of a plain knitting structure, but may be of another structure. It is preferable to use a so-called shirring process for forming a crepe by heating and shrinking after knitting using a polyurethane elastic yarn. And
In addition to this elastic yarn, rayon containing fine tourmaline powder and ceramic fine powder that emits far-infrared rays, as well as synthetic resin fibers such as nylon are used. Examples of this kind of ceramic include sintered bodies such as Al ₂ O ₃ , TiO ₃ , and BaO. The mixing ratio of tourmaline and ceramic is preferably 40 to 60% by weight for the former and 60 to 40% by weight for the latter. Further, in consideration of the feeling, it is preferable to use a blended yarn with cotton or the like. Therefore, the ratio of tourmaline to the ceramic-containing fiber is preferably 10% by weight or more of the entire knitted fabric.

Next, as shown in FIG. 7, the pad 40 is provided with an acrylic resin such as a modified acrylic ester copolymer on both surfaces of a nonwoven fabric 41 made of fibers containing tourmaline and ceramic similar to shorts cloth. Coatings 42a, 4
2b. These coating films 42a and 42b are
This is to prevent the nonwoven fabric from being loosened or unbalanced and clumped during washing of the shorts. Acrylic resins are particularly preferred because they do not impair the performance of tourmaline and ceramics, but other synthetic resins may be used. The coating amount is 2
６6 g / m ² (dry) may be sufficient. If the amount is less than 2 g, the protective ability of the nonwoven fabric 41 is lacking. If the amount exceeds 6 g, the effects of tourmaline and the like are reduced, and the protective ability does not increase much. After the coating films 42a and 42b are formed, they are passed through a calendar roll at about 120 ° C. and hot pressed to smooth the surface and improve the feeling. The nonwoven fabric 41 is formed of tourmaline and ceramic-containing fibers in an amount of 50% by weight or more, and the remainder is formed of other fibers having a deodorizing effect, but may be formed of tourmaline and ceramic-containing fibers of 100%. The thickness is 1-3
mm. The range in which such a pad 40 is provided may be an area corresponding to the lower abdomen of the human body. As shown in FIGS. 4 and 6, an appropriate portion from the upper end of the crotch part 20 to the upper edge of the front body 10 It may be provided. Although the area and a plan shape arbitrarily selected, will require 100 cm ² or more because fade effect and too small an area.

As shown in FIGS. 4 and 6, the crotch portion 2
The height H of the front surface of 0 is preferably about 10 cm to 15 cm from the bottom. Normal sanitary shorts are 9c from the bottom
However, in this case, the discharge may leak from the front surface when lying down, and it is necessary to widen the attachment range of the waterproof cloth 50 in order to prevent this.

In the above embodiment, the shorts are shown as being formed from three-piece draped cloth into three pieces of a front body 10, a crotch portion 20, and a back body 30, but the present invention is not limited to this. The part and the back body may be formed from an integral two-piece cloth. Further, it may be formed from a tubular knitted fabric knitted by a circular knitting machine.

[0016]

According to the present invention, as described above, shorts are formed from a knitted fabric containing at least 10% by weight of a fiber containing tourmaline and ceramic, and the shorts are formed in a range corresponding to the lower abdomen of the front body. Since the pad containing 50% by weight or more of fiber containing tourmaline and ceramic is attached, not only the whole waist is surrounded by negative ions and far-infrared radiation, but also the lower abdomen is particularly exposed to strong negative ions and far-infrared rays. Therefore, the therapeutic effect such as menstrual pain can be enhanced.

Further, since the crotch portion is provided from the bottom to a high position on the front of the front body and the waterproof cloth is adhered to the inner surface, there is no leakage of the discharged material when the person lies down.

In addition, since the pad is provided on both sides with a synthetic resin film that does not reduce the performance of tourmaline or ceramic, the pad is not deformed or unevenly distributed by washing, and the therapeutic effect is not reduced.
