However, when nonwoven fabrics are used for the top and backsheets, excretion fluid leaks unless at least some processing is performed on the nonwoven fabric as the backsheet. As one of the processes, it is conceivable that an elastic liquid barrier sheet, for example, an elastic plastic film is interposed and joined between two nonwoven fabrics. In this case, a pressure-sensitive adhesive is densely applied to enhance the joining integrity. It is preferred to apply them, but their elasticity and flexibility will be impaired.

てあることがより好ましい。As illustrated in FIGS. 3 to 5, a plurality of groups of helical adhesives 14 extending in the lateral direction are applied and distributed almost all over the inner surfaces of the top and back sheets 6, 7. In order to spirally apply the pressure-sensitive adhesive as described above, for example, a pressure-sensitive adhesive that has been softened by heating (so-called hot melt) while transferring a continuous sheet to be a top and a back sheet at a given speed in its length direction. Mold) is sprayed onto the sheet from a coating nozzle, and at the same time, air of a given pressure is spirally blown from an air spray port provided around the nozzle to act on the adhesive. . The spiral pressure-sensitive adhesive group 14 may be distributed at a substantially uniform density over substantially the entire inner surface of the top and back sheets 6 and 7, but is defined for positioning the elastic members 4 and 5 and the core 8. Area 15,
In the areas 16 and 17 (however, the area 17 is not provided in the back sheet 7), it is more preferable that the distribution density is higher than the other areas.

９の所与部位に設ける。Leg and waist elastics extending into the regions 15, 16 defined by spiral adhesives 14 located along the concave edge 13 of the back sheet 7 and the ends of the front and rear regions 10, 11, respectively. Element
4 and 5, respectively, and a barrier sheet 9 is provided on the inner surface of the back sheet.
Joined through groups. The leg surrounding elastic member 4 includes a first elastic member 4A and a second elastic member 4B. First
The second elastic members 4A and 4B are arranged such that the portions near both ends thereof cross each other, a portion extending from the crossing portion to the outer end is fixed with the group of spiral adhesives 14 in the region 15, and a central portion of the spiral adhesive is formed. Not fixed in 14 groups. However, the spiral adhesive 14 group may be located in a region where the central portion is located, and the central portion may be fixed. Although not shown, the leg surrounding and waist surrounding elastic members 4 and 5 can be attached to the upper surface of the barrier sheet 9 instead of being attached to the inner surface of the back sheet 7. In this case, instead of providing the regions 15 and 16 where the spiral adhesive 14 group has a high distribution density on the back sheet 7, the respective regions are provided on a given portion of the barrier sheet 9.

In this case, a known tape fastener or the like may be provided on both sides of the rear section 11 (see FIG. 2). A fastening means is provided. Further, depending on the article, the core 8 may not be arranged.

いることができる。The top and back sheets 6 and 7 are nonwoven fabrics having elasticity in the vertical and horizontal directions, the core 8 is a mixed molded product of fluff pulp, water-absorbing polymer particles and heat-welding fibers, and the barrier sheet 9 is an elastic material in the vertical and horizontal directions. The elastic members 4 and 5 may use one or more thread-like or belt-like rubber or plastic films, respectively.

のの一つである。More, as the nonwoven fabric is a material of the top and back sheets 6,7, a basis weight of 25 to 45 g / m 2,
A web is formed by carding hot crimped fibers having a fineness of 0.5 to 3d, and this is heat-treated to give a sheet-like form. As the heat-crimped fiber, for example, one of the preferable ones is “EP fiber” (trade name) obtained from “Chisso Corporation”.

ともに伸縮するから、物品が着用者の身体に適合密着す
る。According to the article of the present invention, the barrier sheet interposed between the top and back sheets, which is a stretchable nonwoven fabric, can prevent excretion liquid from leaking, and the barrier sheet also has stretchability and has top and back sheets Is intermittently bonded to at least one of the above and expands and contracts with these sheets, so that the article fits and fits the wearer's body.

トップおよびバックシートの伸縮性および柔軟性を阻害
する割合が少ない。Since the application state of the adhesive group for joining the barrier sheet and the top and back sheets is spiral or zigzag, the apparent adhesive width is wide, and there is a portion where the adhesive does not exist in the width region. Accordingly, the barrier sheet can be widely bonded to the top and back sheets with a small amount of the adhesive, and the rate of obstructing the elasticity and flexibility of the top and back sheets by applying the adhesive is small.

することができる。On the other hand, in the region where the leg surrounding elastic member and the core are located, the distribution density of the spiral or zigzag pressure-sensitive adhesive group is higher than in other regions, so that they can be firmly held.
バリヤーシートは、伸長時に不織布のように繊維交絡
が緩んだり繊維接合が解かれたりして収縮応力が急速に
低下することが少ないプラスチックフィルムからなるか
ら、物品の生地全体に所要の収縮応力を維持させるにき
わめて有効である。The barrier sheet is made of a plastic film that, when stretched, does not rapidly reduce contraction stress due to loosening of fiber entanglement or loosening of fiber bonding, like a nonwoven fabric, so that the required contraction stress is maintained throughout the fabric of the article It is extremely effective in causing
吸水性コアが位置することにより、前記適合密着なら
びに脚囲り弾性部材によるシール効果と相まって排泄液
の漏れを一層有効に防止することができる。The location of the water-absorbing core makes it possible to prevent leakage of excreted liquid more effectively in combination with the above-mentioned conforming close contact and the sealing effect of the leg surrounding elastic member.
