Description

  This invention relates to sanitary underwear.

  Conventionally, as this type of sanitary underwear, a technique for attaching a stretch tape having stretchability between, for example, the front and rear end edges of a crotch fabric in order to keep the sanitary napkin fit to the skin when worn is Patent Document 1, 2 is proposed.

  Patent Document 1 discloses a stretch with strong elasticity such as rubber tape on the back surface of the crotch outer fabric, which is a stack of two fabrics, a hygroscopic outer fabric (outer fabric) and a water-repellent back fabric (inner fabric). Shorts having a tape are disclosed. In other words, the shorts has a cross fabric attached to the front body side slightly closer to the front body side than the center of the back surface of the front fabric in a state of intersecting the stretch tape at right angles, and the cross fabric has its left and right end edges. It is sewn on the left and right edges of the outer fabric. And the stretch tape is sewn by zigzag stitching along the longitudinal center line of the front fabric and over the entire length in the length direction of the front fabric, and the back body side of the stretch fabric is above the cross fabric The stretch tape is stretched and sewn on the front fabric, and the sewn portion of the front fabric is sewn back and forth to gather.

  On the other hand, Patent Document 2 discloses a second crotch cloth for holding and holding a sanitary napkin on the inner side surface of a stretchable crotch cloth (first crotch cloth) of a shorts body. Is provided in a state of being sewn to the shorts body, and both left and right edges thereof are not coupled to the shorts body, and is provided on the back side of the second crotch cloth and in the longitudinal direction of the second crotch cloth. Stretch tape is attached along the center line, and the length of the left and right edges of the second crotch is shorter than the length of the left and right edges of the elastic crotch side to be sewn And the length of the stretch tape is shorter than that of the second crotch cloth to be sewn, and the second crotch cloth is stretched to the left and right edges to stretch the second crotch.

Utility Model Registration No. 3066708 Japanese Patent No. 3372510

  By the way, in Patent Document 1, when a sanitary napkin is attached to a predetermined portion of a crotch cloth and a short is worn, both the front and back fabrics of the crotch cloth are stretched, and the stretch tape and the cross fabric are also stretched. The napkin will be closely attached to the crotch, and even when the body is moved by intense exercise etc., the stretch tape and the cross fabric are crossed, so it is possible to prevent lateral displacement of the sanitary napkin. In addition, the cross fabric itself is thicker and more rigid than both the front and back fabrics (crotch cloth), so that the shape of the entire crotch cloth can be held without shrinking and the sanitary napkin can be laterally contracted (twisted). Although it is possible to prevent the sanitary napkin from shifting back and forth when the body is moved by strenuous exercise, etc., that is, the sanitary napkin is shifted back and forth (vertical displacement). It is difficult to prevent, there is a problem in that.

  In Patent Document 2, the second crotch cloth is attached to a stretchable crotch cloth (first crotch cloth) via a stretch tape, and both left and right edges of the second crotch cloth are stretched. The second crotch cloth is sewn to the shorts body, and the gathers are brought close together by sewing the second crotch cloth back and forth with the stretch tape stretched. When the panties are worn with the sanitary napkin applied to the cross section, the cross-sectional shape in the width direction of the second crotch cloth is the vicinity of both the left and right edges of the second crotch cloth and the second crotch cloth. The center line portion in the longitudinal direction of the cloth is substantially W-shaped so that it swells in the human body direction, the center line portion in the longitudinal direction of the second crotch cloth is in close contact with the cleft portion, and the left and right sides of the second crotch cloth around it Adjacent to both edges of the wearer's skin Although it is possible to prevent the sanitary napkin from slipping and kinking even when the body is moved due to intense exercise etc., in some cases, the sanitary napkin can be prevented. However, it fits more than necessary, and it becomes difficult to feel the unpleasant part and the skin, so that there is a problem that some wearers feel uncomfortable.

  This device has been made in consideration of the above-mentioned matters, and its purpose is such that even when the body is moved by intense exercise etc., the sanitary napkin does not shift and does not feel uncomfortable without kinking. An object of the present invention is to provide a sanitary undergarment that can obtain an appropriate fit.

In order to achieve the above object, the sanitary undergarment of the present invention is waterproof to hold an absorbent article on the inner surface side of an underwear body mainly composed of a front body, a back body and a crotch. While providing a cloth,
The crotch part (common name: gusset part) has a stretch tape attached to the inner surface side along its longitudinal center line part,
Furthermore, the stretch tape has an expansion / contraction suppression functional portion at the center of the crotch cloth, and has an expansion / contraction functional portion before and after the expansion / contraction suppression functional portion (Claim 1).

In this invention, the stretch tape changes the weaving density of the weft with respect to the warp applied in the longitudinal direction thereof, thereby reducing the expansion / contraction suppressing function portion that suppresses the elongation, and the weft density of the weft with respect to the warp. It is composed of the stretchable function part that does not change,
Further, the stretchable function portion has a length in the longitudinal direction shorter than the crotch side to be sewn for gathering at least the longitudinal center line portion of the crotch fabric,
When the stretch tape is sewn to the underwear body, it is preferable that the stretchable portion is sewn in a stretched state (claim 2).

  In the device according to claim 1, if the sanitary underwear is worn with the sanitary napkin applied to the waterproof cloth, the front and rear of the center of the crotch are stretched by the elastic function part, but the shape of the center of the crotch is Because it is held without contraction by the expansion / contraction suppression function part and without stretching, the sanitary napkin can be stably held at a predetermined position of the crotch, even when the body is moved by intense exercise, The sanitary napkin can be prevented from shifting while maintaining the fit of the sanitary napkin to the skin.

  In particular, in the device according to claim 2, since the gathers are gathered at least at the front and rear stretch function parts of the stretch control function part provided at the longitudinal center line part of the crotch cloth, the sanitary napkin is held by the waterproof cloth. When wearing sanitary underwear in the state, at least the gather part of the crotch cloth is stretched, and the stress when the stretch acts as a force to pull up the sanitary napkin at the front and back positions of the crotch cloth instead of the center, Therefore, it is possible to fit the sanitary napkin in the center of the crotch without pressing the sanitary napkin more strongly than necessary, and even if the body is moved by intense exercise etc. The shape of the center of the cloth is held without shrinking or stretching, and a force to pull up the sanitary napkin is generated at the front and back positions in the center of the crotch cloth. Because there can be prevented or shift the sanitary napkin, also from or kinks sanitary napkin. Furthermore, since the sanitary napkin can be fitted appropriately, itching and rash caused by pressing the sanitary napkin more strongly than necessary to reinforce the prevention of displacement of the sanitary napkin can be reduced.

The right end edge 5c of the waterproof cloth 5 and the right end edge 4c of the crotch cloth 4 are kept free without being sewn, and the left end edge part 5d of the waterproof cloth 5 and the left end edge part of the crotch cloth 4 are maintained. 4d may be kept free without being sewn.

  Hereinafter, a characteristic configuration will be described.

  The crotch cloth 4 has a rectangular stretch tape 6 having a narrow width a attached to the inner surface along the longitudinal center line (vertical center line). In FIG. 5, A indicated by a two-dot chain line is a longitudinal center line (vertical center line). The stretch tape 6 extends not only between the front and rear end edges 4a and 4b of the crotch cloth 4, but also along the longitudinal center line (vertical center line) A of each of the front body 2 and the back body 3. In particular, the back body 3 may extend along the longitudinal center line (vertical center line) A of the back body 3 to reach the waist.

  As shown in FIG. 1, the stretch tape 6 is a tape having a narrow width a (for example, about 8 to 15 mm and preferably 10 mm), and is a stretchable fabric. The stretch tape 6 has an expansion / contraction suppression function portion 7 at the center of the crotch cloth 4, and has two expansion / contraction function portions 8 a and 8 b before and after the expansion / contraction suppression function portion 7. Furthermore, it has the expansion / contraction suppression functional portion 7 that suppresses elongation by changing the driving density of the weft yarn with respect to the warp yarn applied in the longitudinal direction of the stretch tape 6 (the direction indicated by the double arrow B), It is comprised so that it may be pinched | interposed into two said expansion-contraction functional parts 8a and 8b. Moreover, as shown in FIG. 5, in order to gather the longitudinal center line (vertical center line) A between the specific position a of the front body 2 and the front body side specific position b of the crotch cloth 4, In order to gather the longitudinal center line (vertical center line) A between the back body side specific position c and the specific position d of the back body 3, the stretchable functional portion 8a of the stretch tape 6 is as shown in FIG. It has a length F (<E) in the longitudinal direction (B direction) shorter than the length E between the a and b along the front body 2 and the crotch cloth 4 to be sewn, and the stretch tape 6 has the length As shown in FIG. 1, the telescopic function portion 8 b has a length H (B direction) shorter than the length G side between the c and d along the crotch 4 to be sewn and the back body 3. (<G). And when the said stretch tape 6 is sewn on the underwear main body 1, it is sewn in the state which each extended the said expansion-contraction functional parts 8a and 8b. For example, the front and rear body 2 and the crotch cloth 4 are sewn to the stretchable part 8a in a stretched state, and the parts of the front body 2 and the crotch cloth 4 are sewn back and forth to gather. 9 is the gather part. Further, the stretch function part 8b is stretched and sewn on the crotch cloth 4 and the back body 3, and the parts of the crotch cloth 4 and the back body 3 are sewn back and forth to gather. 10 is the gathered portion. In this embodiment, when the minimum width I at which the expansion / contraction suppression function portion 7 of the crotch cloth 4 intersects is 70 mm to 80 mm, the length J of the expansion / contraction suppression function portion 7 is preferably 50 mm to 70 mm, and more preferably 60 mm. Further, the length G between c and d is preferably about 115 mm, and the length between e and b is preferably about 40 mm. e is the position of the intersection of the stitched portion M and the longitudinal center line (vertical center line) A.

  Thus, when the shorts S are worn while the sanitary napkin is held by the waterproof cloth 5, the gathered portions 9 and 10 formed on the stretchable functional portions 8a and 8b located at the front and rear of the stretchable restraining functional portion 7 are extended. However, the stress when stretched acts as a force for pulling up the sanitary napkin not at the center of the crotch cloth 4 but at the front and back positions in the center of the crotch cloth 4. It is possible to fit the sanitary napkin to the cruciform part and the skin more than necessary, and to fit it moderately, and even if the body is moved by intense exercise etc., the shape of the center of the crotch will shrink The sanitary napkin is held without being stretched, and a force for pulling up the sanitary napkin is generated at the front and rear positions in the center of the crotch cloth 4. Shift or, also, it is possible to prevent the or kinks sanitary napkin.

  The front end edge 5a of the waterproof cloth 5 is sewn with the lower end of the front body 2 and the stitching part M, and the rear end edge 5b of the waterproof cloth 5 is sewn with the lower end of the rear body 4 and the stitching part N. However, the present invention can also be applied to a waterproof cloth 5 ′ larger than the waterproof cloth 5. That is, as shown in FIG. 7, the front edge portion 5a ′ of the large waterproof cloth 5 ′ is directly stitched with the front body 2 beyond the position of the stitched portion M indicated by a two-dot chain line, and the waterproof cloth 5 ′. The rear edge 5b ′ is directly stitched with the back body 3 beyond the position of the stitched portion N indicated by the two-dot chain line. In this case, the right edge 5c ′ of the waterproof cloth 5 ′ is sewn over the right edge 2c of the front body 2, the right edge 4c of the crotch 4, and the back body 3, and the left edge of the waterproof cloth 5 ′. The portion 5d ′ may be sewn over the left end edge portion 2d of the front body 2, the left end edge 4d of the crotch cloth 4 and the back body 3, and the rear end of the right end edge 5c ′ of the waterproof cloth 5 ′. Only the rear edge portion n ′ of the edge portion m ′ and the left edge portion 5d ′ of the waterproof cloth 5 ′ is stitched, and the other right edge portion 5c ′ and left edge portion 5d ′ are free. You may make it keep to.
