Description

  The present invention relates to a stool processing sheet and a paper diaper, and more particularly to a stool processing sheet and a paper diaper that captures excrement such as stool so as not to leak outside.

This type of loose stool processing sheet and paper diaper (hereinafter referred to as an absorbent article) can be found in, for example, Patent Document 1 and Patent Document 2.
That is, as for the conventional absorbent article, the absorption pad used by applying to the use surface of a pants type diaper and a paper diaper is mentioned.

  The absorption pad shown in Patent Document 1 includes a top sheet that passes through the excretory fluid facing the skin, a liquid-permeable permeation sheet that passes through the excretory fluid, and the back side of the permeating sheet, and the excretory fluid is placed on the back side. A liquid-impermeable sheet to be held is sequentially provided, and a barrier cuff standing on the surface side is provided. And in the said surface sheet, the permeation | transmission hole of many excretion liquids is formed in the whole area | region facing the excretion site | part of a wearer or its circumference | surroundings.

  On the other hand, the paper diaper shown in Patent Document 2 is a surface sheet located on the skin side of the wearer, an impervious sheet that is located on the outer surface side of the product and does not substantially allow excretion to permeate, and between them. And an intervening absorber.

The absorber has a two-layer structure consisting of a lower layer absorber and an upper layer absorber, and the upper layer absorber has passage holes through which soft stool can pass, and the lower layer absorber and the upper layer absorber One or both are constituted by a fiber assembly made of tow.

  However, in Patent Document 1, the liquid component contained in the excreted loose stool passes through the permeation holes and is absorbed by the absorber, but the solid content mixed in the loose stool is difficult to penetrate the top sheet. Diffuses on top sheet.

  As a result, loose stool containing solids will leak sideways from the diaper, and the caregiver will need to wash the wearer's dirty diaper and underwear, and more labor to wash the stool that has adhered to a wide area of the skin. Has a problem.

  Moreover, in patent document 2, although the tow | toe which was excellent in the absorption assistance function is used for the said absorber, since this tow | toe is arrange | positioned on the lower surface of the surface sheet which contacts a wearer's skin directly, immediately after excretion The function is not exhibited for stool that has not passed through the top sheet. That is, the loose stool immediately after excretion diffuses the upper surface of the top sheet in contact with the skin of the wearer.

  In particular, the solid content mixed in the soft stool diffuses the top surface of the top sheet without passing through the permeation holes.For example, in the case of a wearer who is lying down, the soft stool spreads widely and reaches the back of the wearer. The skin that is in direct contact is stimulated and the adverse effect on the skin is increased, and the wearer has many problems to solve such as rough skin and discomfort as well as the caregiver taking a lot of trouble. Yes.

  Therefore, the object of the present invention is to prevent the spread of loose stool by inhibiting the momentum during the excretion of loose stool, and to remove the solid content in the loose stool without passing through the liquid-permeable surface sheet of the loose stool sheet. An object of the present invention is to provide a sheet for stool processing and a paper diaper that can be reliably captured.

In order to achieve the above object, the present invention has the following technical means.
That is, if it demonstrates using the code | symbol in an accompanying drawing corresponding to an Example, the invention described in Claim 1 will capture the excrement like the loose stool which the wearer excreted inside so that it may not leak outside. In the loose stool processing sheet, the loose stool sheet (1) includes a liquid-permeable surface sheet (2) formed in a rectangular shape and a liquid-permeable surface sheet (2) formed in the rectangular shape. And a fiber bundle (T1) composed of a bundle of the long fibers by connecting one end of a plurality of long fibers in series on the upper surface , and the fiber bundle (T1) fluffs a bundle of long fibers intertwined. The sheet for soft stool (1) further includes at least an arrangement in which a plurality of transversely-bound fiber bundles (T1) are arranged in parallel along the longitudinal direction with respect to the liquid-permeable surface sheet (2). ) Liquid-permeable surface sheet (2) of paper diaper (N) A loose stool processing sheet, characterized in that so as to use held against the liquid-permeable topsheet (SE) top.
According to the above, the excreted loose stool is received on the upper surface of the fiber bundle (T1) of the loose stool sheet (1) held on the liquid permeable surface sheet (SE) of the disposable diaper (N). The momentum is stopped by the bundle of long fibers whose volume per unit area is increased by fluffing the bundle of intertwined long fibers of the fiber bundle (T1).

According to the second aspect of the present invention, the absorbent is provided at least in the middle in the longitudinal direction and in the middle in the width direction between the liquid-permeable top sheet (SE) and the liquid-impermeable sheet of the paper diaper (N). Hydrophobic barrier cuffs (9, 9) that are interposed and project upward at both side edges of the liquid-permeable surface sheet (SE) are formed along the longitudinal direction, and the liquid-permeable surface sheet (SE) The elastic cuffs (10, 10) are provided on the respective barrier cuffs (9, 9) in an integrated manner, and the barrier cuffs (9, 9) are projected due to contraction of the elastic elastic members (10, 10) when mounted. in the paper diaper to be, the liquid-permeable topsheet (SE) fiber bundles on the upper surface by one end coupled to the long fibers in series consisting of a bundle of the long fibers of a plurality of (T8), at least the wearer From the excretion site to the back area (BE) To the site of a paper diaper which is characterized in that so as to disposed in rows at regular intervals in the longitudinal direction on the upper surface of the liquid permeable topsheet (SE).
According to the above, the excreted loose stool is stopped by the fiber bundle (T8) to prevent diffusion, and is arranged in a row from the excretion site of the wearer to the site corresponding to the back region. The spread fiber bundle (T8) prevents the wearer from spreading widely to the back area (BE) even when the wearer is lying down.

  The present invention has the following effects.

According to the sheet for loose stool treatment and the paper diaper according to the present invention, the fiber bundle is increased in volume per unit area by fluffing a bundle of intertwined long fibers. While the momentum is stopped by the bundle, it can be prevented from spreading widely by at least the fiber bundle disposed from the wearer's excretion site to the site corresponding to the back region, the solid content mixed in the inside is the above Captured by the fiber bundle. Thereby, the skin of a wearer's back side can be protected and it can prevent that a stool leaks to the outer side of a paper diaper.
In addition, the drainage of soft stool that has passed through the fiber bundle and leaked onto the upper surface of the liquid permeable surface sheet of the paper diaper is prevented from being leaked to the outside by the barrier cuff and transmitted through the liquid permeable surface sheet. Of course, the drainage is absorbed by the absorber.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention relates to a stool processing sheet and a paper diaper. First, an example of the stool processing sheet 1 of the present invention will be described with reference to FIGS. The stool processing sheet 1 is a stool processing sheet that captures excrement such as stool excreted by a wearer within a narrow range so as not to leak outside. Are connected in series to the upper surface of the liquid-permeable top sheet 2 formed in a rectangular shape by a heat welding portion HS in which one end of a plurality of water-repellent or hydrophobic fibers is heat-welded by, for example, heat sealing. A plurality of tows formed by bundling the fiber bundle T1 at regular intervals in the longitudinal direction of the liquid-permeable surface sheet 2 Arranged in rows. The fiber bundle constituting the fiber bundle T1 includes long fibers and fibers obtained by cutting the long fibers.

  And the stool processing sheet | seat 1 comprised as mentioned above is used by being applied to the paper diaper mentioned later based on FIG. Specifically, examples of the filament (long fiber) include fibers of PET, PP, PE, and the like, and filaments of a core-sheath structure using these as materials. The fineness of the filament can be, for example, about 1 to 16 dtex, preferably about 1 to 8 dtex, and may be a non-crimped fiber, but a crimped fiber is more preferable.

  For example, the filament can be used in the form of a tow formed by bundling about 3,000 to 1,000,000, preferably 30,000 to 800,000 single fibers. In opening the tow, for example, a method in which the tow is passed over a plurality of opening rolls, and the tow width is gradually expanded as the tow progresses can be used.

On the other hand, the liquid-permeable surface sheet 2 can be a thermal bond nonwoven fabric, a spun bond nonwoven fabric, or the like, and among the nonwoven fabrics, a hydrophilic nonwoven fabric can be used. As the nonwoven fabric of the top sheet, one having a basis weight of 10 to 50 g / m ² , preferably 10 to 30 g / m ² can be used.

  Here, it attaches to the long fiber which comprises the fiber united body T1, and demonstrates in comparison with a short fiber. The long fiber web preferably includes crimped long fibers as the long fibers, and the crimp ratio (JISL0208) of the long fibers is preferably 0 to 50%, and preferably 0 to 30%.

  In the crimping of the long fiber and the short fiber, the crimp rate of the long fiber is the length A when the long fiber is stretched, which is the difference between the length A when the long fiber is stretched and the length B of the original long fiber. And is obtained from the following formula: Crimp rate = ((A−B) / A) × 100%. The crimp rate of short fibers is measured in the same manner, but the crimp rate is measured with fibers having a length of 10 mm or more.

  More specifically, the long fiber means a fiber having a length of 70 mm or more, preferably 100 mm or more, when the fiber length is measured by the average fiber length measuring method of JISL1015. The total length of the web to be measured is less than 100 mm. When the web extends over the entire length of the web, the fibers of the web are long fibers and are generally called continuous filaments. Generally called tow. On the other hand, the short fiber means a fiber having a fiber length measured by the same measurement method as that for the long fiber of less than 70 mm, more preferably 10 to 50 mm.

  Next, the operation of the stool processing sheet 1 will be described with reference to FIG. Here, the detailed description of the paper diaper will be omitted, and will be omitted. However, the paper diaper N shown in FIG. 4 is used with the soft stool processing sheet 1 shown in FIG. 1 configured as described above. The At that time, the liquid-permeable surface sheet 2 of the sheet for soft stool processing 1 is held by being applied to the upper surface side of the liquid-permeable surface sheet SE of the paper diaper N.

  During the excretion of loose stool, the degree of diffusion of the loose stool varies depending on various conditions such as the solid content mixed in the soft stool, the ratio of the solid content and the excretion liquid, its viscosity, and the posture of the wearer.

The excreted loose stool is received on the upper surface of the fiber bundle T1 of the loose stool processing sheet 1 held on the upper surface side of the liquid-permeable surface sheet SE of the paper diaper N, and the entangled length of the fiber bundle T1 By fluffing the bundle of fibers, the momentum is stopped by the bundle of long fibers whose volume per unit area is increased, so that it is prevented from spreading widely.
Therefore, the solid content mixed in the soft stool is captured by the fiber bundle T1, and the liquid content contained in the soft stool passes through the liquid-permeable surface sheet 2 and the liquid-permeable surface sheet SE on the lower surface thereof. Absorbed by the absorbent body inside the liquid-permeable surface sheet SE.

  Further, on the liquid permeable top sheet 2, a plurality of transverse fiber bundles T1 in which one ends of long fibers are bonded by, for example, heat sealing are arranged in parallel at regular intervals along the longitudinal direction. The excretion of loose stool that is excreted can be prevented from leaking to the outside since the diffusion is blocked by the wall of the fiber bundle T1 formed at every interval, although it varies depending on the directionality. The structure or arrangement of the fiber bundle is not limited to a straight line as described above, and various arrangements are conceivable.

  Next, the first to fifth modifications of the stool processing sheet will be described with reference to FIGS. 5 (a), 5 (b), 6, 7, and 8. FIG. First, in Fig.5 (a), the code | symbol 4 is the sheet | seat for stool processing which concerns on a 1st modification, Comprising: This sheet | seat 4 for stool processing changes the arrangement | positioning of the said fiber binding body, In the said Example. On the upper surface of the same rectangular liquid-permeable topsheet 2 described above, a plurality of fiber bundles T2 are arranged in a row at regular intervals in the width direction.

  Therefore, in the loose stool processing sheet 4, the plurality of fiber bundles T <b> 2 are arranged in a row as described above, and thus the excreted loose stool is the wall of the fiber bundle T <b> 2 formed at intervals. This prevents lateral diffusion and prevents leakage to the outside. Moreover, the solid content mixed in the loose stool is captured in the opened fiber bundle T2.

  In FIG. 5B, reference numeral 5 denotes a stool processing sheet according to a second modification, and this stool processing sheet 5 is a fiber bundle that covers the entire upper surface of the liquid-permeable surface sheet 2. T3 is disposed.

  Therefore, in the loose stool processing sheet 5, the excreted loose stool has a volume per unit area by fluffing a bundle of intertwined long fibers disposed over the entire upper surface of the top sheet 2. Is received by the fiber bundle T3 having increased in size, so that diffusion in each direction is prevented. Moreover, the solid content mixed in the loose stool is captured in the opened fiber bundle T3.

A plurality of fiber bundles T4 arranged in the vertical direction of the liquid-permeable surface sheet 2 are arranged.
Therefore, in the stool processing sheet 6, the excreted loose stool is received by the longitudinal and lateral fiber bundles T4 and T5, and thus it is possible to prevent diffusion in both the longitudinal and lateral directions.

In FIG. 7, reference numeral 7 denotes a stool processing sheet according to a fourth modified example, and the stool processing sheet 7 includes a plurality of rows arranged in rows at regular intervals between three columnar bundles T <b> 5. The fiber bundle T6 is disposed in the longitudinal direction of the liquid-permeable surface sheet 2.
Therefore, in the stool processing sheet 7, the excreted loose stool is received by the vertical and horizontal fiber bundles T5 and T6. Therefore, as in the third modification, both the vertical and horizontal directions are used. Diffusion can be prevented.

Moreover, in FIG. 8, the code | symbol 8 is the sheet | seat for stool processing which concerns on a 5th modification, Comprising: As for this sheet | seat 8 for stool processing, the fiber binding body T7 formed in the several U shape is the said liquid permeability. The top sheet 2 is arranged in rows in the vertical direction at regular intervals.
Therefore, in the stool processing sheet 8, the excreted stool is likely to collect in the center of the stool processing sheet 8, and the diffusion in the dorsal direction can be suppressed.

Next, an embodiment of the disposable diaper of the present invention will be described with reference to FIG.
In FIG. 9, the disposable diaper N has an absorbent body (not shown) interposed between a liquid-permeable surface sheet SE corresponding to the skin side of the wearer and a liquid-impermeable sheet (not shown) disposed on the outside. . In the paper diaper N, a liquid-permeable surface sheet SE is disposed above the absorber, and hydrophobic barrier cuffs 9, 9 protruding upward are longitudinally formed on both side edges of the liquid-permeable surface sheet SE. It is formed along the direction.

  Elastic barrier members 10, 10 are integrally fixed in the stretched state by a hot melt adhesive or the like on the barrier cuffs 9, 9 integrated with the liquid-permeable surface sheet SE, and are arranged in the longitudinal direction. When the disposable diaper N is attached, the barrier cuffs 9 and 9 are in a protruding state due to the contraction of the elastic elastic members 10 and 10.
