Example Embodiment
[0166] [Example 1]
[0167] Using a spunbond layer composed of ethylene propylene copolymer resin with a fiber diameter of 14.7 μm, the weight per square meter is 15 g / m 2 The nonwoven fabric (spunbond-meltblown-spunbond laminated nonwoven fabric, also referred to as SMS hereinafter) (the nonwoven fabric in this state is referred to as Comparative Example 5). Next, pass the SMS non-woven fabric through image 3 The matching embossed steel roller 43 shown in Figure 4 The convex roller 51 shown in is subjected to surface treatment and two-stage treatment to obtain a nonwoven fabric. The height of each convex part 410 in the roller 41 of the matching embossed steel roller 43 used is 2.8 mm, and the meshing depth of each convex part 410 of the roller 41 and each concave part 420 of the roller 42 is 2.7 mm. In addition, the distance (gap) between the convex portions 410 adjacent to each other in the rotation axis direction is 7 mm, and the distance (gap) between the convex portions 4...
Example Embodiment
[0168] [Example 2]
[0169] Using a spunbond layer composed of acrylic resin with a fiber diameter of 17.7μm, and a weight of 15g / m per square meter 2 Non-woven fabric (spunbond-meltblown-spunbond laminated non-woven fabric, hereinafter also referred to as SMS). Next, this SMS nonwoven fabric was subjected to two-stage treatment under the same conditions as in Example 1 to obtain a nonwoven fabric.
Example Embodiment
[0170] [Example 3]
[0171] Using a spunbond layer composed of ethylene propylene copolymer resin with a fiber diameter of 12.9 μm, the weight per square meter is 18 g / m 2 Non-woven fabric (spunbond-spunbond-meltblown-spunbond laminated non-woven fabric, hereinafter also referred to as SSMS. Softener is mixed into the spunbond layers on both sides of the SSMS non-woven fabric). Next, this SSMS nonwoven fabric was subjected to two-stage treatment under the same conditions as in Example 1 to obtain a nonwoven fabric.
