  • the line drawing portion of the side graphic 159 may be black, or the line writing portion and the inside of the line drawing may be black. If the waistline elastic body 44 is white, the brightness of the waistline elastic body 44 and the side graphic 159 are different, and therefore the visibility of the end 44a of the waistline elastic body 44 can be improved. In addition, if only the line-written portion of the central graphic 154 is black or colored, the uncomfortable feeling of the previous graphic sheet 151 can be suppressed. Of course, the waistline elastic body 44 and the side graphic 159 may change not only the brightness but also the hue or the saturation. In addition to changing any one of hue, lightness, and saturation, a plurality of them may be changed.
  • the number of graphics 154, 158, and 159 provided on the previous graphic sheet 151 is not limited to three, and may be four or more. Further, the side graphic 159 does not need to be provided on both sides of the central graphic 154, and only one of them may be provided. Further, although the previous graphic sheet 151 provided on the front waistline member 6 has been described, it may be applied to a rear graphic sheet provided on the rear waistline member 7 although not shown.
  • the light transmittance is measured as follows using, for example, a cross light metering color difference meter Z-300A manufactured by Nippon Denshoku Industries Co., Ltd. First, measurement is performed in a state where a shielding object that shields light is arranged between one detection unit and another detection unit, and zero correction is performed. Next, after removing a shielding object arranged between one detection unit and another detection unit, measurement is performed in a state where there is nothing blocking light, and standard correction is performed. Next, the outer surface sheet 42 having the front and rear waist elastic body 44 as the object is measured in a state where the outer sheet 42 is disposed between one detection unit and another detection unit.

  • the visibility of the waist elastic body 44 was confirmed.
  • the waistline elastic body 44 was made of 320 dtex and snapped back at a predetermined position while being stretched 3.2 times.
  • the first object is an SMS fiber nonwoven fabric having a mass of 10 g / m 2
  • the second object is an SMS fiber nonwoven fabric having a mass of 13 g / m 2
  • the third object is a spunbond having a mass of 17 g / m 2
  • the fourth object is an air-through fiber nonwoven fabric having a mass of 30 g / m 2

  • the second object is 83.2%
  • the third object is 84.4%
  • the fourth object is It was 73.2%
  • the fifth object was 56.8%.
  • the end portion 44a of the front and rear waistline elastic body 44 was difficult to see, and in the first to third objects, the end portion 44a of the front and back waistline elastic body 44 was easily visible.
  • the light transmittance is less than 75%, the end portion 44a is difficult to see.
  • the light transmittance is 75% or more, the end portion 44a is easily visible.
  • the light transmittance is 83% or more, it is easier to visually recognize the end 44a.
  • the diaper 1 and 100 can be changed suitably in the range of this invention, and is not limited to embodiment mentioned above.
  • the present invention is not limited to the diaper 1,100, but can also be applied to defecation training pants, incontinence briefs, and the like.

  • the inner sheet 41 and the outer sheet 42 may be joined by a hot melt adhesive applied to either one of the sheets, or both the inner and outer sheets 41 and 42 may be hot melted. An adhesive may be applied and bonded. Further, the inner and outer surface sheets 41 and 42 do not need to be joined with an adhesive such as a hot melt adhesive.
  • a heat fusion sheet is provided between the inner and outer surface sheets 41 and 42 and the heat fusion sheet is provided. You may join by applying heat. Of course, there is no need to apply heat in this way, and bonding may be performed by a sonic seal. Further, the inner and outer surface sheets 41 and 42 need not be divided into the front waistline member 6 and the rear waistline member 7, and a series of sheets extending from the front waist region 11 to the rear waist region 12 may be used. Furthermore, the numerical values such as the expansion ratio relating to the waistline elastic body 44 are not limited to those described above, and can be changed as appropriate.

Pass the sheet through.
  • a local breakdown occurs between the discharge electrode and the convex portion of the roll, and discharge starts from the discharge electrode toward the convex portion of the roll. Then, concave portions are formed in the graphic sheets 51, 52, 151 due to the current discharged to the convex portions. If the concave portions are formed in the graphic sheets 51, 52, 151 as described above, the bonding between the inner and outer surface sheets 41, 42 and the graphic sheets 51, 52, 151 by a hot melt adhesive or the like can be strengthened.
