Abstract

PROBLEM TO BE SOLVED: To provide an undergarment allowing a woman in a relatively young generation, worrying about very slight leaking of urine to wear without being noticed by people around her, and without having sense of resistance, and preventing water from easily blotting on a body fabric.SOLUTION: This undergarment 1 includes a front body 3, a back body 4, and a gusset part 5, and includes a water absorbing fabric piece 6 on the skin side of the gusset part 5. The water absorbing fabric piece 6 is made of a knitted fabric which is made by knitting a fusing elastic yarn and other yarn by plating knitting, and run-proof processing by fusing the fusing elastic yarn by heat set processing, has a water-repellent processed surface opposite to the skin side, and is sewn on a body fabric 2 on a front edge 5a and a back edge 5b of the gusset part 5. The right and left side parts 6c and 6d are cut and left as they are, more narrowly than the widths 5c and 5d of the gusset part 5.

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 as the muscle elasticity decreased with age. 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 Permissible Literatures 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 leakage” can be worn without being noticed by surrounding people and without a sense of resistance, and moisture can be easily obtained. It is the point which provides the underwear which does not bleed into a body cloth.

  In order to achieve the above-described object, the first characteristic configuration of the anti-wetting fabric 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 of the gusset portion, wherein the water-absorbing fabric piece is formed by knitting a thermal fusion elastic yarn and other yarns by plating, It is composed of a knitted fabric that has been subjected to fraying prevention processing by melting the heat-bonding elastic yarn, and the surface opposite to the skin side is water-repellent, so that it can be worn at the front and rear edges of the gusseted portion. The fabric is sewn, and the left and right side portions are processed so as to be narrower than the width of the gusset portion.

  If there is a leak of a small amount of body fluid from the body, for example, a slight urine leak, the urine is absorbed by the water-absorbing fabric piece provided on the skin side of the gusset area and diffused by the water-absorbing fabric piece. Since the surface opposite to the skin side, that is, the surface facing the body cloth side is water-repellent, it is avoided that urine oozes out to the body cloth side. 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.

  Such water-absorbing fabric pieces are knitted fabrics that are knitted with heat-sealed elastic yarns and other yarns by plating and then frayed by melting the heat-sealed elastic yarns by heat setting. Therefore, even if washing is repeated, the fibers are not frayed from the side portions that have been cut off, and the appearance does not deteriorate. 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 second feature configuration, as described in claim 2, in addition to the first feature configuration described above, a plurality of the water-absorbing fabric pieces are overlapped to form a front edge portion and a rear portion of the gusset portion. It is sewn at the edge, and the width of the left and right side parts 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 parts of the fabric piece on the side far from the skin side. In the point.

  By superposing multiple pieces of water-absorbing fabric pieces, even if the amount of body fluid leaked from the body increases slightly, it will be able to absorb enough, and the water repellent surface of each fabric piece will spread the body fluid into the body fabric It is possible to reliably avoid taking out, and moisture is released relatively quickly due to a heat retaining effect by an air layer formed between the pieces of fabric. In addition, the width of the left and right side parts 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 parts of the fabric piece on the side far from the skin side. The thickness is reduced and good comfort can be secured.

  In addition to the above-described second characteristic configuration, the third characteristic configuration is the left and right side portions of the outermost fabric piece in contact with the body fabric, in addition to the second characteristic configuration described above. Is formed in the same width as 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.

  In the fourth feature configuration, as described in claim 4, in addition to the first or second feature configuration described above, the water-absorbing fabric piece is formed of a low-melting-point polyurethane elastic material on the heat-sealed elastic yarn. A yarn, a mixed yarn containing cotton or cotton other than that is selected, and is composed of a knitted fabric knitted by milling or smooth knitting, and the knitted fabric is formed in a direction perpendicular to the width direction of the gusset portion. It is in the point where the wale is arranged in a posture along.

  By using a low-melting-point polyurethane elastic yarn as the heat fusion elastic yarn and cotton yarn or a blended yarn containing cotton as the other yarn, and using a frayed knitted fabric, a skin-friendly underwear can be provided. 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 along the direction perpendicular to the width direction of the gusset portion, so that it is stretchable along the width direction of the gusset portion. A rich and good fit can be obtained, body fluid leaked from the body can be infiltrated along the wales of the knitted fabric, and infiltration in the width direction of the gusset portion can be effectively suppressed. Therefore, it is possible to effectively suppress the occurrence of a situation that oozes out to the side of the gusset body cloth.

  As described above, according to the present invention, it can be easily worn without being noticed by surrounding people, and can be easily worn without resistance, and moisture does not easily bleed into the body cloth. It is now possible to provide underwear that can be adapted to.

Explanatory drawing of the underwear according to the present invention as seen from the front The explanatory view which looked at underwear by the present invention from the back (A) is explanatory drawing of the water absorbing fabric piece incorporated in the underwear by this invention, (b) is explanatory drawing of the gusset part of the underwear in which the water absorbing fabric piece is incorporated. (A) is explanatory drawing of the gusset part which shows other embodiment of the underwear in which the water-absorbing fabric piece was integrated, (b) is the gusset which shows other embodiment of the underwear in which the water-absorbing fabric piece was incorporated Explanatory drawing Explanatory drawing of the result of having simulated the influence of the leak of a mild bodily fluid using the underwear by this invention.

Hereinafter, shorts which are an example of the underwear by this invention are demonstrated based on drawing.
1 and 2 show the front and back of a single short 1. The shorts 1 has a body cloth 2 cut into a front body 3 and a back body 4 and a gusset portion 5 which are sewn together.

  As the body fabric 2 of the shorts 1, milling with cotton yarn is preferably used. In the present embodiment, the front body 3 and the back body 4 are integrally knitted into a cylindrical shape by a circular knitting machine, and the knitted cylindrical knitted fabric is cut at the ends corresponding to the trunk side and the leg side. Later, the gusset part 5 is sewn on the leg part side, and the two leg parts 8 are formed. The shorts 1 according to the present invention may be sewn by cutting the front body 3 and the back body 4 respectively.

  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 for the raw yarn for knitting the body fabric 2. In addition, as the knitted fabric, milling knitting, smooth knitting, and further, tentacle knitting is suitable.

  Narrow flat rubbers 8a and 9a and decorative elastic lace fabrics 8b and 9b are sewn to the leg 8 and the trunk side end 9 by elastic yarns such as nylon. Hereinafter, the sewn part of each part is referred to as a sewn part 10.

  The shorts 1 is a short for women who suffer from light “urine leakage” in an amount of about 3 cc, and has a water-absorbing fabric piece 6 on the skin side of the gusset portion 5. The fabric piece 6 is a knitted fabric obtained by knitting a thermal fusion elastic yarn and other yarns by plating, and fusing the thermal fusion elastic yarn by heat setting to prevent fraying. The opposite side is water repellent.

  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. Therefore, the plating knitted fabric knitted by feeding the heat fusion elastic yarn and the other yarns to the knitting needles from different yarn feeders is composed of the heat fusion elastic yarn and the other yarns in each knitting loop. Because of the stable arrangement, the heat-sealed elastic yarn can be adjacent to all the loops, and if the heat-sealed elastic yarn is melted by heat-set processing etc., it will surely fray in all loops of the knitted fabric A stop function can be realized.

  Moreover, the transfer of body fluid to the outerwear can be prevented without adversely affecting the wearer's skin by the water-repellent treatment using the processing chemical mainly composed of fluorine. A water-repellent finish can be easily applied to one side of the fray-preventing fabric used as the water-absorbing fabric piece 6 by printing means such as roll printing or pad printing.

  The water-repellent processing by printing is preferably performed on 20 to 80% of the anti-fraying fabric. If the water repellent finish by printing is less than 20% on one side of the fray-preventing fabric, the water repellency is insufficient to prevent the transfer of body fluids to the outerwear, and if it exceeds 80%, the moisture release is deteriorated. And there is a problem that heat builds up.

  Moreover, it is preferable that it is water-repellent by printing in dot shape. According to this configuration, the water repellent function and the moisture releasing function can be distributed and imparted in a well-balanced manner on one surface of the anti-fraying fabric.

  The water-repellent finish may be performed using means other than the above-described textile printing means (for example, a spray type). In this case, the water-repellent finish is applied to 20 to 80% of the anti-fraying fabric. preferable.

  Furthermore, the anti-fraying fabric is preferably deodorized and antibacterial processed, and the body fluid absorbed by the anti-fraying fabric is deodorized by the deodorizing function to maintain a comfortable state for a long time. Can do.

  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).

  FIG. 3A shows a water-absorbing fabric piece 6 obtained by cutting the anti-fraying fabric, and FIG. 3B shows the fabric piece 6 sewn on the gusset portion 5 of the body fabric 2. Some of the states are shown. 3 (a), the water absorbent fabric piece 6 has the left and right side portions 6c, 6d cut into a narrower WL than the side portions 5c, 5d width W of the gusset portion 5. As shown in FIG. (In FIG. 3 (a), the widths W and WL of the gusset portions of the body cloth 2 and the cloth piece 6 are clearly indicated by auxiliary lines), the edges are cut off, and special fraying such as sewing is performed. Stop processing is not performed. And as shown in FIG.3 (b), in the front edge part 5a and the rear edge part 5b of the gusset part 5, and the sewing part 10 applied to the side part of the vicinity from the front edge part 5a and the rear edge part 5b. The body fabric 2 is sewn.

  In the present embodiment, the water-absorbing fabric piece 6 is composed of a knitted fabric knitted by milling or smooth knitting, in which a low-melting-point polyurethane elastic yarn is selected as the heat fusion elastic yarn and cotton yarn is selected as the other yarn. Yes. Cotton or a blended yarn containing cotton is suitable as a delicate skin-friendly yarn, but is not limited thereto, and other types of yarn can be used as long as the yarn has water absorption. It is not particularly limited to cotton yarn.

  When a small amount of body fluid leaks from the body of the wearer of such shorts 1, for example, a slight urine leak, the urine is diffused while being absorbed by the water absorbent fabric piece 6 provided on the skin side of the gusset part 2. Water is retained. And since the surface opposite to the skin side of the fabric piece 6, that is, the surface facing the body fabric 2 side is water-repellent, bleeding of urine from the fabric piece 6 to the body fabric 2 side is avoided. The The left and right side portions 6c, 6d of the fabric piece 6 are processed so as to be narrower than the width of the side portions 5c, 5d of the gusset portion 5, and the fabric piece 6 and the body fabric 2 are bordered at the side portions of the gusset portion 2. Therefore, even if urine that has infiltrated into the cloth piece 6 gradually diffuses to the left and right side parts 5c, 5d of the gusset part 5, the sewing machine 10 perforates the sewing parts 10 of the side parts 5c, 5d of the body cloth 2. There is no oozing into the body cloth 2 through the holes or seams.

  Furthermore, as described above, since the fabric piece 6 is frayed, the fibers are not frayed from the side portions 6c and 6d that have been cut off, even if washing is repeated, There will be no deterioration. Further, the cloth piece 6 is sewn on the body cloth 2 at the front edge part 5a and the rear edge part 5b of the gusset part 5, and the side parts 6c and 6d are not sewn on the body cloth 2, so When worn, the side part against the crotch is soft and good comfort can be secured.

  Moreover, it is preferable to arrange | position with the attitude | position in which the wales of the knitted fabric which comprises the fabric piece 6 in the direction orthogonal to the width direction of the gusset part 5, and it is rich in a stretch property along the width direction of the gusset part 5, and is favorable. A feeling of fit can be obtained, body fluid leaked from the body can be infiltrated along the wales of the knitted fabric, and infiltration in the width direction of the gusset portion 5 can be effectively suppressed. Therefore, it is possible to effectively suppress the occurrence of a situation in which body fluid oozes out to the side portions of the body cloth 2 constituting the gusset portion 5. The crossing angle between at least the direction of the wales of the knitted fabric and the width direction of the gusset portion 5 is preferably in the range of 90 ° ± 45 °, more preferably in the range of 90 ° ± 30 °.

  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.

  In FIG. 5, 3 cc of water is dropped with a pipette from a height of 0.5 cm to the bottom skin side of the gusset portion in the wearing state of the shorts 1 according to the present invention described in FIG. The photograph image when the leakage of the filter paper arrange | positioned at the lower part of a gusset part was confirmed over 1 minute after applying a load of 6.6 g / cm <2> via the acrylic board for the upper part of the dripping position is shown.

  On the right side of FIG. 5, a photographic image is shown when 0.4 cc of water is dropped on a conventional normal short and the leakage to the filter paper is confirmed in a similar manner.

  As a result of being repeated three times each, even with only 0.4 cc of water in the conventional normal shorts, water oozed out of the filter paper, whereas according to the shorts 1 according to the present invention, about 8 times as much Even with 3 cc of water, no water oozes out of the filter paper, and it was confirmed that it was extremely effective.

  Hereinafter, another embodiment will be described. A plurality of absorbent fabric pieces 6 may be superimposed on the gusset portion 5. FIG. 4A shows a case where two pieces of ground pieces 6 (6A, 6B) are superimposed. In this case, the fabric pieces 6A and 6B are both sewn to the body fabric 2 at the front edge portion 5a and the rear edge portion 5b of the gusset portion 5, and the width of the left and right side portions of the fabric piece 6A on the side close to the skin side is increased. In addition, it is preferable that the width of the fabric piece 6B on the side farther from the skin side is processed to be narrower than the width of the left and right side portions.

  By superimposing a plurality of water-absorbing dough pieces 6, even when the amount of body fluid leaked from the body increases slightly, it becomes possible to absorb the body fluid on the water-repellent surface of each dough piece 6A, 6B. It is possible to reliably avoid the bleeding into the fabric 2.

  Further, moisture is released relatively quickly due to a heat retaining effect by an air layer formed between the fabrics 6A and 6B. In addition, the width of the left and right side parts 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 parts of the fabric piece on the side far from the skin side. The thickness is reduced and good comfort can be secured.

  It is preferable that the water repellent performance of the fabric piece 6B far from the skin side is higher than the water repellent performance of the fabric piece 6A closer to the skin side, and the moisture release function is enhanced in the fabric piece 6A closer to the skin side. In the fabric piece 6B on the side farther from the skin side, by increasing the water repellency function, the moisture release performance can be enhanced while effectively preventing exudation to the body fabric.

  As shown in FIG. 4 (b), the left and right side portions of the outermost fabric piece 6 B in contact with the body fabric 2 among the water absorbent fabric pieces 6 (6 A, 6 B) are formed to have the same width as the width of the gusset portion 5. The side portions of the outermost fabric piece 6 </ b> B are preferably sewn to the side portions of the body fabric 2.

  When a plurality of water-absorbing fabric pieces 6 are overlapped, when all the water-absorbing fabric pieces are formed to be narrower than the width of the gusset portion 5 of the body fabric 2, when misalignment occurs in the sewing process, There arises a problem that the outermost fabric piece 6A formed wider than the left and right side portions of the skin-side fabric piece 6B protrudes outside the side portions of the body fabric 2. Even if the position does not shift in the sewing process, the same inconvenience may occur at the time of wearing. However, the left and right side portions of the outermost fabric piece 6B in contact with the body fabric 2 are formed to have the same width as the width of the gusset portion 5 of the body fabric 2, and the side portions of the outermost fabric piece 6B are If the side parts are sewn, the desired performance can be sufficiently exhibited while avoiding such inconvenience.

  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 be provided to a wide generation after the 30s as a comfortable underwear that a woman suffering from light “urine leakage” can wear everyday without resistance.
