Definitions

  • the indicator 1D existing at a position overlapping the concave portion 52 in the thickness direction is caused by the fact that the average thickness of the portion of the exterior sheet 5 where the concave portion 52 exists is thin. Therefore, since it can be easily visually recognized even in the presence of a small amount of excrement liquid, the presence and amount of the excretion liquid can be visually recognized at an early stage. Further, the indicator existing at a position overlapping the ridge portion 51 in the thickness direction maintains the hollow structure of the ridge portion 51 formed on the exterior sheet 5 immediately after the diaper 1 is worn, and the average thickness is increased. Therefore, it is difficult to visually recognize the indicator from the outside.
  • the exterior sheet 5 having the high basis weight region 53 and the low basis weight region 54 is subjected to processing such as partially stretching the constituent non-woven fabric of the exterior sheet 5 using a pair of uneven rolls capable of engaging with each other.
  • the low basis weight region 54 can be formed, and the portion that is not partially stretched can be the high basis weight region 53.
  • the arrangement form of the high basis weight area 53 and the low basis weight area 54 is not particularly limited as long as the abundance ratio described later is satisfied, and is continuous along, for example, the extending direction of the indicator 1D or the direction intersecting the direction. It may be arranged linearly or discontinuously, may be formed in a scattered pattern, or may be formed in the entire sheet.
  • each indicator 1D shown in FIG. 4 is represented so as to have a different basis weight, it is only represented as such for convenience of explanation, and is formed so as to have a different basis weight as shown in the figure. Alternatively, it may be formed so that the basis weight is the same.
  • the abundance ratio of the high basis weight region 53 in the portion overlapping the first indicator in the thickness direction Z is the second. It suffices if it is different from the abundance ratio in the portion overlapping in the thickness direction with the indicator of 2. Specifically, assuming that the abundance ratio of the high basis weight region 53 in the first and second indicators is different, the abundance ratio in the portion overlapping with the other indicators in the thickness direction Z is the abundance ratio in the first indicator. It may be the same as or different from the abundance ratio. Similarly, the abundance ratio in the portion overlapping the other indicators in the thickness direction Z may be the same as or different from the average thickness in the second indicator.
  • the indicator 1D existing at a position overlapping the low basis weight region 54 in the thickness direction has a smaller amount of fibers in the low basis weight region 54 as compared with the high basis weight region 53. Because of this, the presence of excrement fluid and its amount can be visually recognized at an early stage because it can be easily visually recognized even in the presence of a small amount of excretion fluid. Further, the indicator 1D existing at a position overlapping the high basis weight area 53 in the thickness direction is covered with the high basis weight area 53 having a large amount of fibers immediately after the diaper 1 is worn, making it difficult to see the indicator. .. In the wet and pressurized state, the high basis weight region 53 is crushed with the passage of wearing time, so that the visibility of the indicator is gradually improved. As a result, it is possible to more easily and accurately grasp that the appropriate time to change the diaper has arrived.
  • the appropriate thickness of the exterior sheet 5 itself and the sheet recessed portion 58 are combined in the state immediately after wearing the diaper and in the state where a small amount of excrement is absorbed and held. Since it is easy to hide the indicator, the visibility of the indicator from the outside is maintained low.
  • the sheet recessed portion 58 is pushed outward due to the swelling of the absorber 4, the recessed state of the sheet recessed portion 58 disappears, and the exterior Since the thickness of the sheet 5 itself changes so as to become thinner, the visibility of the indicator gradually and remarkably increases with the lapse of wearing time. As described above, the visibility of the indicator is further increased as the amount of excrement absorbed and retained in the absorber 4 is increased, so that the appropriate time to change the diaper can be more easily and easily changed from the outside. It can be grasped accurately.
  • the thickness of the exterior sheet in a dry and unloaded state is 0.3 mm or more and 2.5 mm or less, preferably 0.5 mm or more and 2 mm or less, and more preferably 0.7 mm or more and 1.5 mm or less.
  • ⁇ 5> The thickness of the exterior sheet when wet and pressurized with a load of 0.5 N / cm 2 is 0.1 mm or more and 2 mm or less, preferably 0.2 mm or more and 1.5 mm or less, and more preferably 0.3 mm or more.
  • the absorbent article according to any one of ⁇ 1> to ⁇ 4> which is 1 mm or less.
  • the exterior sheet 5 includes a synthetic fiber having a core-sheath structure in which the core component is polyethylene terephthalate (PET) and the sheath component is polyethylene (PE), and a mixed fiber in which cotton is mixed at a mass ratio of 15: 1.
  • the deployable disposable diaper shown in FIG. 1 was manufactured using a single-layer air-through non-woven fabric (basis weight: 20 g / cm 2 ).

Abstract

L'invention concerne un article absorbant : comprenant un corps absorbant (1A) qui comprend une feuille de surface perméable aux liquides (2), une feuille de prévention de fuite (3) et un absorbant (4) qui est positionné entre les deux feuilles ; présentant une direction longitudinale (X) correspondant à une direction avant-arrière d'un porteur et une direction de largeur (Y) qui est orthogonale à la direction longitudinale ; et présentant une région ventrale (F), une région dorsale (R) et une région de couture d'entrejambe (M). Un injecteur (1D) qui indique la miction par un changement de couleur est disposé sur un côté de surface faisant face à la peau de la feuille de prévention de fuite (3) et une feuille extérieure (5) constituée d'un tissu non tissé est disposée sur un côté de surface non tourné vers la peau de la feuille de prévention de fuite (3). La feuille extérieure (5) recouvre le côté de surface non tourné vers la peau de la région du corps absorbant (1A) où l'injecteur (1D) est disposé. Le taux de variation d'épaisseur de la feuille extérieure est de 20 % à 75 % lorsqu'un état sec et sans charge passe à un état humide et sous pression, sous une charge de 0,5 N/cm2.
