Description

  The present invention relates to an undergarment that includes a front body, a back body, and a gusset part, and has a water-absorbing fabric piece on the skin side of the gusset part, and more particularly to an undergarment that can handle mild urinary incontinence.

  In general, it is known that women have mild “urine leakage” in generations after their thirties due to the burden on the body at the time of delivery and changes in hormone balance due to aging. The number of middle-aged and older women who are suffering from mild “urine leakage” increases in the mid-40s when menopause is reached. The urinary leakage of this age caused a lot of stress urinary incontinence caused by the pelvic floor muscles and the urethral sphincter loosening due to a decrease in muscle elasticity with aging. Symptoms of urge urinary incontinence that sometimes cannot be tolerated may also appear.

  In order to cope with a relatively large amount of urinary incontinence in the elderly, diapers for adults and underwear with a water absorbent pad attached or sewn have been developed. Examples of such underwear are disclosed in Patent Documents 1 and 2.

  In Patent Document 1, when a water absorbent pad is attached to the inner surface of the pants, a body fluid such as urine is transmitted from a perforation hole or a seam of the sewing machine and is exuded by attaching it through a blocking piece. Incontinence pants have been proposed that can be prevented.

  Further, Patent Document 2 includes a crotch portion that can be sewn or worn by a pad that prevents the wearer's body fluid from leaking to the outside. Underwear has been proposed to reduce pleasure.

  The underwear includes an absorbent skin side cloth having a pad sewing surface or mounting surface, and at least one of water repellency and waterproofing disposed on the opposite side of the sewing surface or mounting surface with respect to the skin side cloth. A crotch portion having a backing cloth and a first side cloth having at least one of water repellency and waterproofness arranged along the side edge of the skin side cloth and the side edge of the backing cloth. The side edge portion of the backing cloth has an overhanging portion protruding from the side edge portion of the skin side cloth, and the first side cloth has a width wider than the overhanging portion, When the side edge portion of the cloth is folded back, it is sewn to the side edge portion of the skin-side cloth, thereby forming a raised portion that rises with respect to the sewing surface or the mounting surface.

  Further, Patent Document 3 proposes an underwear using a urine leakage countermeasure fabric in which a front fabric, a water retaining layer, a water absorbing diffusion layer, and a waterproof fabric are provided in this order.

Japanese Patent No. 4266604 JP 2010-261135 A Japanese Patent Laid-Open No. 2005-111181

  However, the underwear described in Patent Documents 1 and 2 is an underwear to which a thick water absorption pad for dealing with a relatively large amount of urine leakage is attached, and has a strong psychological resistance and is worn. May be easily recognized by the outer garment, and it was not easy to use for women in their 30s to 50s who suffer from mild urinary incontinence.

  In order to respond to such people's demands, shorts that have a front body, a back body, and a gusset part, and at least a thin water absorption pad can be attached to the gusset part are provided. There is an annoying problem.

  Therefore, underwear has also been proposed in which a multi-layered fabric piece having a water absorbing layer, a water retaining layer, a waterproof layer, etc. as described in Patent Document 3 is sewn to the gusset portion in advance, but the gusset portion is thick and worn. There is a sense of incongruity, and even a small amount of water infiltrated into the fabric piece oozes through the perforated holes and stitches of the sewing machine and gives discomfort, and in some cases, the fabric fabric bleeds. There was a problem that the outer garment might get dirty with the moisture that was released.

  In order to avoid the problem of moisture permeating through the perforated holes and seams of the sewing machine and oozing into the body fabric, it is difficult to adopt the configuration described in Patent Documents 1 and 2 for thin shorts. However, even if it is adopted, there is a problem that the gusset portion is thick and the hemline is likely to appear on the outer garment.

  In view of the above-mentioned problems, the object of the present invention is that a relatively younger generation woman suffering from a very light “urine leak” can be worn without being noticed by surrounding people and without a sense of resistance, and can easily be hydrated. It is to provide an underwear with good design that does not bleed into the body fabric.

  In order to achieve the above-described object, the first characteristic configuration of the undergarment according to the present invention includes a front body, a back body, and a gusset portion, as described in claim 1 of the claims. An undergarment having a water-absorbing fabric piece on the skin side, wherein the water-absorbing fabric piece is composed of a knitted fabric, and a plurality of knitted fabrics are superimposed and at least a front edge portion of the gusset portion Sewing is performed on the body fabric at the rear edge, and at least one of the plurality of knitted fabrics is arranged so that the wales of the other knitted fabrics intersect with each other.

  For relatively younger women, for example, women in their 30s and 40s, not only water absorption but also fashionability is emphasized, and because of the balance with outerwear, the design has a fit that is shallow and the waist circumference is short. Underwear is preferred. Such underwear inevitably has a small gusset area, and is stretched vertically and horizontally when worn on the body.

  In general, the stretchability of the knitted fabric in the course direction is larger than the stretchability in the wale direction, and when the stretch is greatly extended in the course direction, the opening of the knitted fabric becomes remarkable. When such a knitted fabric is superimposed on a plurality of sheets and used as a water-absorbent fabric piece, if the knitted fabric is superposed with the waling directions aligned, moisture leaked from the body is greatly opened in each knitted fabric. There is a risk that the knit will easily pass through and infiltrate the outside and stain the body fabric.

  Even in such a case, if one of the plurality of knitted fabrics is arranged so that the wales of at least one knitted fabric and the wales of the other knitted fabric intersect with each other, one of the knitted fabrics is in the course direction. Even if the mesh is widened and opened, a part of the stitches are blocked by the other knitted fabric having an angle between the wales, so that the opening of the stitches as a whole is suppressed and moisture does not leak outside. . Also, if there is an angle between the wales, even if one of the knitted fabrics stretches greatly in the course direction and opens, there are many cases where the other knitted fabric does not open so much. As a result, the opening of the stitches is suppressed and moisture does not leak to the outside.

  As described in the second aspect, in addition to the first characteristic configuration described above, the second characteristic configuration is arranged such that the wales of the knitted fabric in contact with the skin are along the lateral width direction of the gusset portion. At the same time, the wales of other knitted fabrics superimposed on the knitted fabric are arranged so as to intersect with the wales of the knitted fabric.

  If the wales of the knitted fabric on the skin side are arranged in the longitudinal width direction from the front edge of the gusset part to the rear edge part, moisture leaked from the body tends to diffuse more quickly along the wale than the course There is a risk of bleeding into the body fabric from the suture line at the front edge of the gusset. Moreover, in the underwear of the above-described design, the course direction greatly extends along the right and left width direction of the gusset portion, and the opening of the knitted fabric becomes prominent. .

  However, when the wales of the knitted fabric on the skin side are arranged along the horizontal width direction of the gusset part, moisture leaked from the body diffuses more quickly in the horizontal width direction than reaching the front edge of the gusset part. It is possible to avoid the occurrence of an unfavorable situation such as bleeding from the suture line at the front edge of the gusset portion into the body cloth. In addition, even when the knitted fabric is stretched in the left-right width direction of the gusset portion, the knitted fabric in the left-right width direction is compared with the case where the knitted fabric wales on the skin side are arranged along the front-rear width direction of the gusset portion. Since the mesh opening is suppressed, it is possible to suppress a decrease in water absorption performance.

  Moreover, because the knitted fabric on the skin side is arranged so as to intersect with the knitted fabric on the skin side so that the wales of the other knitted fabric intersect with the wales on the skin side, the moisture absorbed by the knitted fabric on the skin side It penetrates into other knitted fabrics before reaching the body fabric, and diffuses in the direction of its wales. As a result, moisture is infiltrated in all directions by at least two layers of knitted fabrics arranged so that the wale directions cross each other, and the body fabric is not easily soiled.

  Therefore, even if a minute amount of body fluid leaks from the body, for example, a slight urine leak, it is absorbed by the water-absorbent knitted fabric superimposed on the gusset part and diffused without penetrating into the body fabric. Water is retained.

  In addition to the first or second characteristic configuration described above, the third characteristic configuration is configured to cover the outer urethral orifice with the absorbent fabric piece, as described in claim 3. The front edge of each knitted fabric is sewn on the body fabric on the umbilicus side from the position corresponding to the outer urethral orifice.

  In general, the gusset portion of the underwear is sewn with a fabric serving as a protective layer on the inside of the body fabric, and the front edge portion is around a portion corresponding to the mouth of the external urethra. In other words, until now, no consideration has been given to placing the gusset portion in response to incontinence. For this reason, underwear with a design that fits short, especially around the waist and waist, the area of the gusset area is small, so even if the amount of urine leakage is small, the water-absorbent fabric piece cannot absorb water effectively, There was a risk of getting dirty. However, if the front edge of the knitted fabric is sewn to the body fabric on the umbilicus side from the position corresponding to the outer urethral opening, the periphery of the outer urethral opening is sufficiently covered with the absorbent fabric piece, Even when the area of the portion is small, water can be sufficiently absorbed without soiling the body cloth against mild urine leakage.

  In the fourth feature configuration, as described in claim 4, in addition to any one of the first to third feature configurations described above, at least the skin-side fabric piece of the water-absorbing fabric piece includes: Consists of a frayed knitted fabric, the surface opposite to the skin side is water repellent, and the left and right side portions of the knitted fabric are processed to be cut narrower than the width of the gusset portion. It is in.

  Even if there is a slight urine leak, first, urine is absorbed by the water-absorbing fabric piece provided on the skin side of the gusset portion and diffused by the water-absorbing fabric piece. Even if urine that has infiltrated the dough piece gradually spreads to the left and right sides of the gusset, the left and right sides are processed to be cut narrower than the width of the gusset. There is no oozing into the body cloth through the perforated holes and seams in the sewing part. And since the surface opposite to the skin side surface of the said cloth piece, ie, the surface facing the body cloth side, is water-repellent processed, it can be avoided that urine oozes out to the body cloth side.

  In addition, since the front and rear edges of the gusset part are sewn to the body fabric and the side parts are not sewn to the body cloth, when the underwear is worn, the side part hits the crotch part. Soft and good comfort can be secured.

In the fifth feature configuration, in addition to the fourth feature configuration described above, the frayed knitted fabric is plated with a heat-deformable elastic yarn and other yarns. It is composed of a knitted fabric knitted by knit and frayed by compressing and deforming the heat-deformable elastic yarn by heat setting, and cellulose fibers or cellulose fibers are added to the yarn other than the heat-deformable elastic yarn. The blended yarn to be included is selected and is knitted by milling or smooth knitting.

  Adopting such a fray-proof knitted fabric as a water-absorbing fabric piece will prevent the fibers from fraying from the side parts that have been left untreated even after repeated washing, resulting in poor appearance It is possible to provide underwear that is gentle to the skin without inviting any skin.

In addition, the knitted fabric knitted by milling or smooth knitting is arranged in a posture in which the wales of the knitted fabric are aligned in the left-right width direction of the gusset portion. A good fit and a good fit, and even if the gusset part is stretched greatly in the left-right width direction, the opening of the knitted fabric is suppressed, and body fluid leaking from the body easily infiltrates the body fabric side There is no. Furthermore, since the water-absorbing fabric piece is composed of cellulose fibers, rapid absorption of body fluid leaked from the body can be expected. Cellulose fibers refer to plant fibers such as cotton, regenerated fibers such as rayon and cupra, and semisynthetic fibers such as acetate and triacetate.

  In addition to any one of the first to fifth feature configurations described above, the sixth feature configuration of the sixth aspect is the outermost portion of the water-absorbing fabric piece that contacts the body fabric. The right and left side portions of the fabric piece are formed to have the same width as the width of the gusset portion, and the side portions of the outermost fabric piece are sewn to the side portions of the body fabric.

  When multiple water-absorbing fabric pieces are overlapped, if all the water-absorbing fabric pieces are formed narrower than the width of the gusset, if there is misalignment in the sewing process, There arises a disadvantage that the outermost fabric piece formed wider than the side portion protrudes outside the side portion of the body fabric. Even if the position does not shift in the sewing process, the same inconvenience may occur at the time of wearing. However, if the left and right side parts of the outermost fabric piece in contact with the body fabric are formed to be the same width as the width of the gusset part, and the side parts of the outermost fabric piece are sewn to the side parts of the body fabric, Such inconvenience can be avoided, and the desired performance can be sufficiently exhibited.

  As described above, according to the present invention, a relatively young generation of women who suffer from extremely light “urine leakage” can be worn without being noticed by other people and without a sense of resistance, and moisture can be easily worn. It has become possible to provide underwear with good design that does not bleed into the fabric.

(A) is explanatory drawing of the wearing state of the underwear for elderly people compared with the underwear by this invention, (b) is explanatory drawing of the non-wearing state

Hereinafter, shorts which are an example of the underwear by this invention are demonstrated based on drawing.
1A and 1B show a short 1 in a worn state and a short 1 in a non-wearing state. The underwear according to the present invention is designed for a relatively younger generation woman who suffers from light “urine leakage” in the amount of about 3 cc, for example, women in their late 30s to 40s. It is shallow and the underwear is finished in a fashionable underwear with a short fit around the waist.

  The shorts 1 includes a front body 3, a back body 4, and a gusset portion 5, and a water-absorbing fabric piece 6 serving as a crotch is disposed on the skin side of the gusset portion 5. The water-absorbing fabric piece 6 is formed of a knitted fabric, and a plurality of knitted fabrics (in this embodiment, two knitted fabrics 61 and 62 (see FIG. 2)) are overlapped at least in front of the gusset portion 5. The edge 5a and the rear edge 5b are sewn on the body fabric 2. As will be described in detail later, the knitted fabric that becomes the water-absorbent fabric piece 6 is not limited to two sheets, and a plurality of three or more knitted fabrics may be superposed, of which at least one knitted fabric It is preferable that the wales and the wales of other knitted fabrics are arranged so as to intersect with each other.

  With the shorts 1 attached, the front edge 5a of each knitted fabric 61, 62 is worn on the umbilicus side from the position corresponding to the outer urethral opening so that the absorbent fabric piece 6 covers the periphery of the outer urethral opening. The fabric 2 is sewn. Specifically, the sewing process is performed so that the front edge portion 5a is located about 30 mm to 40 mm above the position corresponding to the outer urethral orifice.

  Until now, no consideration has been given to disposing the gusset portion in response to incontinence. Generally, the gusset portion 5 in which the fabric serving as the protective layer is sewn inside the body fabric is the front edge portion 5a. Is located around the site corresponding to the mouth of the external urethra. For this reason, underwear with a design that fits short, especially around the waist and waist, the area of the gusset part 5 is small, and even if the amount of urine leakage is small, the water-absorbent fabric piece cannot absorb water effectively, There is a risk of getting dirty.

  However, if the front edge 5a of the knitted fabric 6 is sewn on the body fabric 2 on the umbilicus side from the position corresponding to the outer urethral opening, the periphery of the outer urethral opening is sufficiently covered with the absorbent fabric piece. Even if the area of the gusset portion 5 is small, water can be sufficiently absorbed without soiling the fabric 2 against slight urine leakage.

  In addition to natural fibers such as cotton, ultrafine fibers having water absorption properties such as regenerated cellulose fibers such as cupra and viscose rayon, and synthetic fibers such as water-absorbing polyester are used as raw yarns for knitting the body fabric 2. Further, as the knitted fabric, milling knitting, smooth knitting, weft knitting such as sheet knitting, and warp knitting such as Russell knitting is preferably used. In addition, by knitting elastic yarn such as polyurethane into a ground structure, an underwear rich in elasticity can be obtained. Further, it is possible to use a frayed knitted fabric which will be described later. In this case, the leg side edge may be cut off, and there is no need to perform a special fraying prevention process such as sewing.

  In the present embodiment, milling with cotton yarn is suitably used as the body fabric 2. The front body 3 and the back body 4 are integrally knitted into a cylindrical shape by a circular knitting machine, and the knitted tubular knitted fabric is cut at the ends corresponding to the trunk side and the leg side, and then the leg side The gusset portion 5 is sewn to form two legs. The shorts 1 according to the present invention may be sewn after the fabrics of the front body 3, the back body 4 and the gusset portion 5 are cut, and are further sewn after being cut into fine parts. It may be a thing.

  Although not shown in the figure, a narrow flat rubber is sewn to the leg side end 8 and the trunk side end 9 of the underwear 1, and the elastic lace fabric for decoration is stretchable such as nylon. In some cases, it is sewn with a thread.

  Based on FIG. 2 (a) showing the front surface of the shorts 1 and FIG. 2 (b) showing the back surface, the configuration will be further described in detail. The two water-absorbing fabric pieces 61 and 62 are knitted fabrics obtained by knitting a heat-deformable elastic yarn and other yarns by plating, and fusing the heat-deformable elastic yarn by melting the heat-set process. It is composed of the ground.

  Plating knitting is a method in which a plurality of yarns are fed from different yarn feeders to knitting needles, and the arrangement of yarns in each knitting loop is stably determined. Accordingly, the plating knitted fabric knitted by feeding the heat-deformable elastic yarn and the other yarns to the knitting needles from different yarn feeders is composed of the heat-deformable elastic yarn and the other yarns in each knitting loop. The heat-deformable elastic yarn can be adjacent to all the loops, and if the heat-deformable elastic yarn is melted by heat setting, etc., it will fray reliably in all the loops of the knitted fabric. Stop function can be realized.

  In the present embodiment, the water-absorbing fabric pieces 61 and 62 are selected from a low-melting point polyurethane elastic yarn as the heat-deformable elastic yarn and a mixed yarn of cotton yarn and rayon as the other yarn, and are knitted by milling or smooth knitting. It consists of knitted fabric. Cellulose fibers or blended yarns containing cellulose fibers are preferred as delicate skin-friendly yarns. However, the yarn is not limited to this, and other types of yarns can be used as long as they have water absorption. Yes, it is not particularly limited to cellulose fibers.

  In addition to using a heat-fusible elastic yarn such as a low-melting point polyurethane elastic yarn as the heat-deformable elastic yarn, it is also possible to use a polyurethane urea elastic fiber. Due to heat treatment such as heat set processing, the polyurethane urea elastic fibers are compressed and deformed at the contact points between the polyurethane urea elastic fibers or between the polyurethane urea elastic fibers and the partner yarn, and the polyurethane urea elastic fibers are bonded to each other or against the polyurethane urea elastic fibers. Since the yarn is fixed, the polyurethane urea elastic fiber and the partner yarn from the knitted fabric are not easily removed, and a knitted fabric in which curling and fraying are suppressed can be obtained. In other words, the heat-deformable elastic yarn is not limited thereto as long as it has a characteristic of being melted or compressed and deformed by heat treatment.

  Furthermore, the water-absorbing fabric pieces 61 and 62 may be constituted by warp knitted fabrics. As the warp knitted fabric, a knitted fabric knitted by half tricot knitting or double tricot knitting is preferably used.

  Moreover, the water repellent process is given to the surface on the opposite side to the skin side of each water absorbing fabric piece 61,62. Water repellent processing using a processing agent containing fluorine as a main component can prevent the transfer of body fluid to outerwear without adversely affecting the wearer's skin. The water-repellent finish can be easily applied to one side of the anti-fraying fabric described above by printing means such as roller printing, screen printing, and ink jet printing.

  It is preferable that the water-repellent processing by printing is applied to 40% or more with respect to the area of one side of the anti-fraying fabric. If the water-repellent processing by printing is less than 40% with respect to the area of one side of the fray-preventing fabric, there is a problem that the water repellency for preventing the transfer of body fluid to the outerwear is insufficient.

  The water-repellent processing may be performed using means other than the above-described printing means (for example, a spray type). In this case, it is preferable that 40% or more of the anti-fraying fabric is subjected to water-repellent processing. .

  It is more preferable if each water-absorbing fabric piece 61, 62 is deodorized and antibacterial processed, and the odor of the body fluid absorbed by the fabric piece is deodorized by the deodorizing function, and maintains a comfortable state for a long time. be able to.

  For example, as disclosed in Japanese Patent No. 3787675, fibers serving as a raw yarn are treated with a treatment liquid containing chitosan and / or modified chitosan, a carboxylic acid polymer, zinc oxide and a binder resin to form these coating layers. By using the prepared fibers, it is possible to obtain a fabric such as an underwear having an excellent deodorizing effect and having good washing resistance (durability).

  2A, the left and right side portions 6c and 6d of the fabric piece 61 on the skin side where the fraying prevention fabric is adopted have a width W1 of the side of the gusset portion 5. The portions 5c and 5d are cut to be narrower than the width W, the edges are cut off, and no special fraying prevention processing such as sewing is performed.

  The left and right side portions of the fabric piece 62 on the body fabric 2 side are cut to the same width as the width W of the side portions 5c and 5d of the gusset portion 5, and are sewn together with the body fabric 2. Accordingly, the fabric piece 62 on the body fabric 2 side does not necessarily need to be a fray-preventing fabric, but is preferably subjected to water repellent processing, deodorization and antibacterial processing.

  As described above, since the shorts 1 have a shallow rise and a short fit around the waist, the area of the gusset portion 5 is inevitably small, and stretches vertically and horizontally when worn on the body. The dough piece 6 is greatly stretched in the left and right width directions of the gusset portion 5.

  FIG. 3A shows a milled knitted fabric on which the water-absorbing fabric pieces 6 are knitted. In general, the stretchability of the knitted fabric in the course direction is larger than the stretchability in the wale direction, and in particular, milling knitting has a characteristic of extending very well in the course direction.

  As shown in FIG. 3 (b), the moisture absorbed in the knitted fabric 6 due to urine leakage mainly diffuses and infiltrates along the wale, so that the course direction of the knitted fabric 61 on the side in contact with the skin is gusseted. It can be considered that the portion 5 is arranged along the left-right width W direction, in other words, the wale direction thereof is along the front-rear width direction of the gusset portion 5. This is because the front-rear width is longer than the left-right width of the gusset portion 5, and therefore, there is an advantage that a water retention amount can be obtained.

  However, as shown in FIG. 3 (c), when the gusset portion 5 is stretched greatly in the left-right width W direction, the opening of the knitted fabric becomes prominent, resulting in a decrease in water absorption performance and easily infiltrating outside. There is a risk of the fabric getting dirty.

  Therefore, as shown in FIG. 4A, the knitted fabric 61 on the side in contact with the skin has a gusseted portion so that the opening is suppressed even if the gusseted portion 5 extends greatly in the left-right width W direction. 5 are arranged along the left-right width direction W.

  Then, as shown in FIG. 4B, the wales of the knitted fabric 62 on the body fabric 2 side overlapped with the knitted fabric 61 intersect with the wales of the knitted fabric 61 (in the present embodiment, orthogonal). Has been.

  In other words, the course of the knitted fabric 61 on the side in contact with the skin is arranged along the direction from the front edge portion 5a to the rear edge portion 5b of the gusset portion 5, and another knitted fabric 62 superimposed on the knitted fabric 61 is overlapped. Are arranged along the direction from the front edge portion 5a to the rear edge portion 5b of the gusset portion 5.

  As shown in FIG. 5 (a), when a small amount of body fluid leaks from the body of the wearer of such shorts 1, for example, a slight urine leak occurs, a water-absorbent fabric piece provided on the skin side of the gusset portion 2 The knitted fabric 61 is diffused and retained while urine is absorbed. Since the surface of the knitted fabric 61 opposite to the skin side, that is, the surface facing the body fabric 2 side is water-repellent, urine bleeding from the knitted fabric 61 to the body fabric 2 side is suppressed.

  Since the wales of the knitted fabric 61 on the skin side are arranged along the left-right width direction of the gusset portion 5, even if the knitted fabric 61 is extended in the left-right width W direction of the gusset portion 5, Is suppressed, and a decrease in water absorption performance is suppressed. As shown by the long and short dashed line in FIG. 5A, most of the water absorbed in the skin-side knitted fabric 61 infiltrates while diffusing in the wale direction.

  The left and right side portions 6c, 6d of the knitted fabric 61 are cut off to be narrower than the width of the side portions 5c, 5d of the gusset portion 5, and the knitted fabric 61 and the knitted fabric 62 (body cloths) are formed at the side portions of the gusset portion 2. 2) is cut off, even if urine that has infiltrated into the knitted fabric 61 gradually diffuses to the left and right side portions 5c, 5d of the gusset portion 5, the side portions 5c of the knitted fabric 62 (body cloth 2), There is no oozing into the body cloth 2 through the perforation holes and stitches of the sewing machine in the 5d sewing portion.

  Furthermore, since the knitted fabric 61 is frayed, even if washing is repeated, fibers are not frayed from the side portions 6c and 6d that have been cut off, and the appearance may deteriorate. No. The knitted fabric 61 is sewn on the body fabric 2 at the front edge portion 5a and the rear edge portion 5b of the gusset portion 5, and the side portions 6c and 6d are not sewn on the body fabric 2. When worn, the side part against the crotch is soft and good comfort can be secured.

  Even if moisture leaks from the stitches of the knitted fabric 61 or moisture leaks from the side of the knitted fabric 61, it is received by the knitted fabric 62 on the body fabric 2 side. And infiltration into the body cloth 2 is avoided.

  As shown in FIG. 5 (b), the knitted fabric 62 on the body fabric 2 side is arranged so as to overlap the knitted fabric 61 on the skin side so as to intersect with the wale of the knitted fabric 61 on the skin side. Moisture absorbed by the knitted fabric 61 on the skin side quickly infiltrates into the knitted fabric 62 before reaching the body fabric 2 and is diffused in the wale direction.

  As a result, water is retained while diffusing in all directions by at least two layers of the knitted fabrics 61 and 62 arranged so that the wale directions intersect, and the body fabric 2 does not easily get wet.

  In this way, even if there is a slight urine leak or the like, water is retained without penetrating into the body fabric 2 by being absorbed and diffused by the water-absorbing knitted fabrics 61 and 62 superimposed on the gusset portion 5. The

  Such shorts 1 can absorb not only mild urinary incontinence but also a small amount of bodily fluids that are unexpectedly discharged, such as postmenopausal irregular bleeding, without being noticed by those around you. It is a comfortable and comfortable underwear that can be worn without resistance and that moisture does not easily bleed into the body fabric.

6 (a) and 6 (b) show the relationship between the arrangement direction of the wales of the knitted fabric 61 in contact with the skin and the gusset portion 5. FIG. Although it has already been described that the wales of the knitted fabric 61 in contact with the skin are arranged along the lateral width direction of the gusset portion 5, specifically, the front edge portion 5a center and the rear edge portion 5b of the gusset portion 5 are described. When an angle between a line segment T perpendicular to the line segment L connecting the center and theta _T, at least knitted fabric 61 it is necessary that wales are disposed at theta _{T <45} ° to become posture. And, preferably θ _{T <30} °, more preferably may be arranged in theta _{T <15} ° to become posture, it is not necessarily a theta _{T =} 0 °, in consideration of the angular variation in manufacturing θ _T <5 ° is most preferred. FIG. 6A shows an example of θ _T = 30 °, and FIG. 6B shows an example of θ _T = 15 °.

FIG. 6C shows the relationship between the arrangement direction of the wales of the knitted fabric 61 in contact with the skin and the arrangement direction of the wales 62 of the knitted fabric on the body fabric 2 side. Although it has already been described that the wales of the knitted fabric 62 on the body fabric 2 side superimposed on the knitted fabric 61 in contact with the skin intersect with the wales of the knitted fabric 61, specifically, the knitted fabric 61 in contact with the skin. When the angle (intersection angle) formed with the wale arrangement direction D is θ _D , at least the knitted fabric 62 needs to be arranged in a posture in which the wale is θ _D > 15 °, and θ _D > 30 °. If better. Further, it is preferable that it is arranged in a posture where θ _D > 45 °, more preferably θ _D > 60 °, and θ _D = 90 ° is not necessarily required. However, in consideration of angle variation during manufacturing, θ _D <85 ° is most preferred. FIG. 6C shows an example in which θ _D = 60 °.

The above-mentioned shorts 1 with crossing angles θ _D <15 °, θ _D = 30 °, θ _D = 45 °, θ _D = 60 °, and θ _D = 90 ° are each worn as a sample on a torso with a urine hole. Then, 2 ml of water was dripped at a time from the urine hole, and after a minute, the shorts 1 were removed and a test for confirming the presence or absence of the exudation on the body cloth was performed a plurality of times.

As a result, when the crossing angle is θ _D <15 °, there is clearly oozing out into the body cloth, when θ _D = 30 °, there is a slight oozing out into the body cloth, and when θ _D > 30 °, No exudation to the fabric was observed. It is also confirmed that even when θ _D = 30 °, it is possible to prevent bleeding into the body fabric by thickening the yarns for knitting the knitted fabrics 61 and 62 or increasing the knitting density. It is sufficient that at least the knitted fabric 62 is arranged in a posture in which the wale is θ _D > 15 °.

  As a sample, the same test as described above was performed on the shorts 1 in which the arrangement direction of the wales of the knitted fabric 61 in contact with the skin and the arrangement direction of the knitted fabric wales 62 on the body fabric 2 side were aligned. Whether the wale is arranged in the left-right width direction of the gusset portion or in the front-back width direction of the gusset portion, the oozing into the body cloth was confirmed.

  FIGS. 8A and 8B show a shorts 1 in a wearing state and a shorts 1A in a non-wearing state, which are in proportion to the shorts 1 of the present invention. The shorts 1A are designed for relatively elderly women, and are finished in underwear that has deep crotch and has room around the waist.

  Therefore, the gusset portion does not stretch greatly in the left-right width direction in the mounted state, and the wales of the knitted fabric on both the skin side and the fabric side are perpendicular to the left-right width direction of the gusset portion, that is, in the front-rear width direction. It arrange | positions so that it may follow, and it is comprised so that the bodily fluid leaked from the body may be diffused along the wale of a knitted fabric. Along with the left and right width direction of the gusset portion 5, it is rich in elasticity and a good fit can be obtained, but the fashionability is poor and the degree of freedom of outerwear is also limited. In this example as well, it is preferable that the wales of at least one knitted fabric of the knitted fabric to be a water-absorbing fabric piece and the wales of the other knitted fabric intersect with each other.

Hereinafter, another embodiment of the present invention will be described.
In the embodiment described above, an example in which two water-absorbing dough pieces are superimposed on the gusset portion has been described, but the number of superimposed sheets is not limited to two, and a plurality of three or more sheets are superimposed. Also good.

  If the wales of the knitted fabric in contact with the skin are arranged along the left-right width direction of the gusset portion, and the knitted fabric wales overlapped with the knitted fabric are arranged so as to intersect the knitted fabric wales Good.

  For example, as shown in FIG. 7A, when three knitted fabrics are superimposed, the wales of the knitted fabric 61 on the skin side are arranged along the left-right width direction of the gusset portion, and the intermediate knitted fabric 62 It is preferable that the wales intersect with the wales of the knitted fabric 61 on the skin side, and the wales of the knitted fabric 63 on the body side are along the wales of the knitted fabric 61 on the skin side.

  The thickness of the raw yarn knitting each knitted fabric may vary. FIG. 7B shows an example in which the thickness of the raw yarn knitting the intermediate knitted fabric 62 is thicker and thicker than the other knitted fabrics 61 and 63. By changing the number of superimposed knitted fabrics and the thickness of the raw yarn, it is possible to adjust the water retention / absorption force, the wearing feeling, and the like.

  FIG. 7C shows an example in which four knitted fabrics 61, 62, 63, 64 are superimposed. The wales of the third and fourth knitted fabrics from the skin side intersect with the wales of the upper knitted fabrics. However, as described above, the wales need not be orthogonal.

  At least a water-absorbing fabric piece in contact with the skin was knitted with a heat-deformable elastic yarn and other yarns by plating, and was fray-stopped by melting or compressively deforming the heat-deformable elastic yarn by heat setting. The knitted fabric may be formed of knitted fabric, but all of the water-absorbing fabric pieces may be formed of a knitted fabric that has been frayed.

  Of the water absorbent fabric pieces, the left and right sides of the outermost fabric piece in contact with the body fabric are formed to have the same width as the width of the gusset portion, and the side portions of the outermost fabric piece are sewn to the side portions of the body fabric. Preferably it is worn.

  When multiple water-absorbing fabric pieces are overlapped, if all the water-absorbing fabric pieces are formed narrower than the width of the gusset, if there is misalignment in the sewing process, There arises a disadvantage that the outermost fabric piece formed wider than the side portion protrudes outside the side portion of the body fabric. Even if the position does not shift in the sewing process, the same inconvenience may occur at the time of wearing. However, if the left and right side parts of the outermost fabric piece in contact with the body fabric are formed to be the same width as the width of the gusset part, and the side parts of the outermost fabric piece are sewn to the side parts of the body fabric, Such inconvenience can be avoided, and the desired performance can be sufficiently exhibited.

  As for the knitted fabric other than the outermost knitted fabric in contact with the body fabric, it is preferable that the left and right side portions are processed so as to be narrower than the width of the gusset portion, similarly to the knitted fabric on the skin side. Furthermore, it is preferable that the width of the left and right side portions of the fabric piece on the side close to the skin side is processed so as to be narrower than the width of the left and right side portions of the fabric piece on the side far from the skin side. The thickness gradually decreases over time, and good comfort can be secured.

  It is preferable that the water repellent performance of the fabric piece on the side far from the skin side is higher than the water repellent performance of the fabric piece on the side close to the skin side. By increasing the water repellency of the fabric piece on the far side, the moisture release performance can be enhanced while effectively preventing the fabric from exuding.

  In the above-described embodiments, the knitted fabric wales that contact the skin are arranged so as to be along the left-right width direction of the gusset portion, and the knitted fabric wales superimposed on the knitted fabric are the wales of the knitted fabric. However, the underwear according to the present invention is not limited to such an embodiment, and at least one knitted fabric among a plurality of knitted fabrics arranged in the gusset portion is described. It is only necessary that the ground wales and the wales of other knitted fabrics intersect with each other.

  If the wales of at least one knitted fabric among the knitted fabrics and the wales of the other knitted fabric intersect with each other, one of the knitted fabrics greatly expands in the course direction and opens. Even so, the other knitted fabric does not open so much, the opening of the stitches is suppressed as a whole, and moisture does not leak to the outside.

  In this case, the wales of the knitted fabric 61 in contact with the skin do not need to be arranged along the left-right width direction of the gusset portion 5, and the arrangement direction of the wales of at least one knitted fabric and the wales of the other knitted fabrics The relationship with the arrangement direction may be the relationship as described with reference to FIG.

  The design of the shorts shown in FIGS. 1 and 2 is an example, and it goes without saying that the width of the right and left side portions of the water-absorbent fabric piece 6 can be appropriately set according to the design and size. It is. The underwear according to the present invention can also be applied to underwear other than shorts.

  The underwear according to the present invention can be publicly provided to a relatively younger generation after the thirties as a comfortable underwear that a woman suffering from mild “urine leakage” can wear everyday without resistance.
