  • the first roll 91 is heated to a temperature lower than the melting point of the thermoplastic resin used for the outer sheet 30. In this embodiment, it is heated to about 80-110 ° C. Therefore, the fibers of the outer surface sheet 30 are not thermally fused and the fibers are easily drawn. Therefore, in a part of the portion where the concave portion 37 is formed, the fiber is stretched and bent, and the touch can be improved. Moreover, in the stretched part, the fibers are thinned, and the touch can be made more supple.
  • the bosses 93 are intermittently arranged in the axial direction, and the concave strips 98 are continuously arranged in the axial direction in the second roll 92, so that the outer surface sheet 30 corresponds to the separated portion of the boss 93.
  • a groove along the imaginary line 36 is formed in the portion. This is because, between the bosses 93 of the first roll 91, the outer sheet 30 is pulled by these bosses 93 to form linear strips. By forming the groove in this way, the outer sheet 30 is easily bent along this, and a more supple texture can be realized.
  • the groove extends only in the horizontal direction X and does not extend in the vertical direction Y. If the groove is formed in both the vertical direction Y and the horizontal direction X, the outer surface sheet 30 becomes easy to extend in both the vertical direction Y and the horizontal direction X, and the outer surface is produced when the diaper 1 is manufactured. When the sheet 30 is conveyed, the shape becomes unstable. Therefore, the groove is formed only in either one. In addition, if the groove extends in the longitudinal direction Y, the outer sheet 30 is easily extended in the lateral direction X. When the hook element 81 is pulled in the lateral direction X, the lateral sheet X is accompanied by this. It may extend and the adhesiveness of a waist opening may fall during wearing of the diaper 1. However, in this embodiment, this can be prevented by the groove extending in the lateral direction X.
  • the entire outer surface sheet 30 is prevented from extending by forming concave portions 37 in both side regions 35 of the outer surface sheet 30, but by providing a crimping portion in both side regions 35, Further, the inadvertent extension of the outer sheet 30 can be prevented.
  • compression-bonding part can be formed when the outer surface sheet 30 crimps
  • the crimping part can be provided only on the outer sheet 30, or can be provided by heating and pressurizing the outer sheet 30 and another sheet laminated thereon.
  • the present invention relates to the improvement of the following disposable wearing article 1.
  • the disposable wearing article 1 has a longitudinal direction Y and a lateral direction X, a skin facing surface and a non-skin facing surface that is the opposite side, front and rear end edges 14 and 15 extending in the lateral direction X, and the longitudinal direction Y Both side edges 16 extending to the front and rear waist regions 11 and 12, the crotch region 13 located between the front and rear waist regions 11 and 12, the inner surface sheet 20 located on the skin facing surface, and the non-skin facing surface It includes an outer sheet 30 positioned and an absorber 40 positioned between the inner and outer sheets 20 and 30 and positioned at least in the crotch region 13.
  • the outer surface sheet 30 includes a central region 34 having a plurality of recesses 37 arranged intermittently in the lateral direction X, and both side regions 35 located on both sides of the central region 34 in the lateral direction X. 35 extends continuously from the crotch region 13 to the front and rear waist regions 11 and 12.
  • the above invention can include at least the following embodiments.
  • the concave portion 37 is formed along an imaginary line 36 extending in the lateral direction X, and a plurality of the imaginary lines 36 are arranged in the longitudinal direction Y.
  • a leak prevention sheet 50 is further included between the absorber 40 and the outer sheet 30, and the central region 34 overlaps the leak prevention sheet 50.
  • a hook element 81 constituting a mechanical fastener is attached to either one of the front waist region 11 and the rear waist region 12 and the both side regions 35, and the hook element 81 is attached to either one of them.
  • the loop element 82 which comprises the mechanical fastener which can connect can be attached.
  • An elastic body 51 extending along the both side edges 16 is fixed between the inner and outer surface sheets 20 and 30 so as to be shrinkable, and the elastic body 51 is disposed in the both side regions 35.
  • channel located on the said virtual line 36 is formed.
  • the outer surface sheet 30 is formed from a fiber sheet.
  • the fiber sheet is a fiber nonwoven fabric formed of filaments.
