Interval mutual property body 5a becomes smaller, then the protrusion 6a and recess portion 6b in a line bumps row 6 can be made fine to be formed, can not only be made into
Quantity for the recess portion of the access of the body fluid such as urine or sweat increases, and can keep its shape.The deformation in aptychus portion 60 as a result, just
Increase for the viewpoint of the flexibility of cloth 1, evapotranspiring property of moisture, thermal diffusivity and penetrability preferably.According to such purport, pleat portion 60
The mutual spacing interval in mutual interval, i.e. protrusion 6a is preferably 2mm~7mm.Spacing interval mutual protrusion 6a is more
Good is 3.00mm~6.25mm.By the spacing narrower intervals for keeping protrusion 6a mutual, the pleat careful since skin texture can be formed, therefore
And appearance beautifies, further, since every 1 pleat becomes smaller with the contact area of skin, so skin sense of touch becomes good, further
Ground is since the surface area of per unit volume becomes larger, so the absorbability of the body fluid such as urine or sweat improves.On the other hand, by making protrusion
Spacing interval mutual 6a broadens, and can moderately inhibit the elastic force of linear elastic bodies 5a, can reduce manufacturing cost.
Furthermore in Fig. 1, Fig. 2, about the protrusion 6a and recess portion 6b for forming adjacent concave-convex row 6, to form each concave-convex row
The morphogenetic mode of shape that 6 protrusion 6a is connected with recess portion 6b in Y-direction continuity is shown, but also can be according to threadiness
The item number of elastomer 5a or configuration mode etc., and generate protrusion 6a and the discontinuous parts recess portion 6b.In addition, phase can also be formed
The state that the forming position of the protrusion 6a and recess portion 6b of adjacent concave-convex row are staggered in X-direction mutually forms concave-convex row 6.In such feelings
When shape, pleat portion 60 has the protrusion 6a and recess portion 6b that such as form adjacent concave-convex row 6 in the discontinuous part of Y-direction.That is, pleat portion
60 are formed by unevenly forming protrusion 6a and the pattern of recess portion 6b.About in multirow bumps row 6 adjacent concave-convex row it is each
Person becomes in the formation pattern of protrusion 6a and recess portion 6b as formed protrusion 6a and recess portion 6b in the position that X-direction is mutually staggered
In the case of pattern, for example, when cloth 1 to be used as to the situation of surface material 15 body fluid such as urine on one side in X-direction branch, while in Y
Direction is advanced, so diffusivity more improves, so as to more promote lateral leakage protection function.
