The wearing article having front and rear waist regions that include a first pair of lateral zones opposed to each other in a transverse direction X and extending in a longitudinal direction Y and a second pair of lateral zones opposed to each other in the transverse direction X and extending in the longitudinal direction Y, respectively. An inner sheet is provided in the respective first lateral zones with mount members defining first engagement regions and hook elements of mechanical fastener are attached to a chassis via these mount members. The respective second lateral zones of the inner sheet define second engagement regions and provided with loop elements attached thereto. The front and rear waist regions are provided with waist elastic members attached thereto under tension so as to extend in the transverse direction X. The mount members are formed by fibrous sheet adapted to be engaged with the hook members and thereby define third engagement regions.

Wearing article and method of folding up the same

A pant-type wearing article configured so that fasteners used to connect front and rear waist regions with each other can be engaged with and disengaged from each other in a repetitive manner. Of the front and rear waist regions, at least one waist region, for example, the front waist region is formed in its transversely opposite lateral zones with inelastic regions being neither elastically stretchable nor elastically contractible in a waistline direction. These inelastic regions are provided with first fastener members selected from the first fastener members and second fastener members. The front waist region is further formed inside the respective inelastic regions as viewed in the waistline direction with a plurality of film-like joints defined by integrated sheet members forming the lateral zones.

A wearing article configured so that loop elements engaged with associated hook elements will not ride up or curl up in the course of the production process. Mount members are attached to an inner sheet in a front waist region so as to extend along first lateral zones of the front waist region and hook elements are attached to a chassis by the intermediary of these mount members. Loop elements are attached to the inner sheet in a rear waist region so as to extend along second lateral zones of the rear waist region. Third regions of the respective mount members are formed with sticking zones operatively associated with outer lateral edges of the respective loop elements. The sticking zones formed on the respective mount members are temporarily joined to the loop elements as the hook elements are engaged with the associated loop elements.

Method of making wearing article

A pant-type wearing article configured so as to prevent a lateral zone of a front waist region and an associated lateral zone of a rear waist region which should remain fastened together from being needlessly disengaged from each other. In the pant-type wearing article an outer surface of a base sheet strip constituting a front fastener component is bonded to a fixed region defined on an inner surface of a front lateral zone. The front lateral zone includes a free region to which the base sheet strip is not bonded. The free region normally takes a posture folded back in a waistline direction so that an outer surface of the front lateral zone lies inside.

Pants-type wearing article

A wearing article configured so that hook elements of a mechanical fastener can be firmly attached to a chassis and the hook elements can be held in engagement with loop elements of a mechanical fastener tightly without correspondingly increasing a manufacturing cost. The wearing article has front and rear waist regions that respectively include a first pair of lateral zones and a second pair of lateral zones, these lateral zones in each pair are opposed to each other in a transverse direction X and extending in a longitudinal direction Y. An inner sheet is provided in the first lateral zones with mount members attached thereto and hook elements are attached to the diaper via the mount members. In the second lateral zones, the inner sheet is provided with loop elements attached thereto. First and second arrays of the hook elements include deformed regions created over the entire areas thereof by pressure-treatment.

Wearing article and method of making the same

A pants-type wearing article includes front and rear waist regions connected to each other by a fastener member in a detachable and refastenable manner. Each of the fastener member includes a sheet-like supporting element adapted to be folded in a Z-shape or an inverted Z-shape as the front and rear waist regions are put flat together and a fastener element. The supporting element has a top section, a bottom section and an intermediate section connecting the top and bottom sections. Between opposed surfaces of the bottom section and the intermediate section, a sheet-like liner section is provided so as to extend from a bottom section's openable end of the bottom section along these opposed surfaces toward a top section's joint end.

The present invention provides an absorbent article imparting superior comfort during wearing without inhibiting an absorbent property of an absorbent body, and a manufacturing method thereof. In the stretchable non-woven fabrics composed of a stretchable thermoplastic fiber and a heat-adhesive fiber having a lower melting point than that of the thermoplastic fiber which is arranged on a skin non-contacting side of a chassis, a low-stretchability portion is formed, in which the stretchability of the stretchable non-woven fabrics is lowered, at least in a portion thereof which overlaps an absorbent body in a thickness direction. The low-stretchability portion is formed by heating and pressurizing the portion of an elasticized non-woven fabric being extended.
