1. A speaker diaphragm comprising:
a plurality of sheet-forming bodies configured to be stacked,
wherein two sheet-forming bodies adjacent to each other are integrated, and these integrated two sheet-forming bodies are peelable to be two sheet-forming bodies, and
wherein an entangled portion is provided over the entire boundary between the adjacent two sheet-forming bodies.
2. The speaker diaphragm according to claim 1,
wherein the entangled portion is formed by entangling fiber of one sheet-forming body permeating another sheet-forming body with fiber of the another sheet-forming body.
3. The speaker diaphragm according to claim 2,
wherein a thickness of the entangled portion is smaller than a thickness of one sheet-forming body of the two sheet-forming bodies.
4. The speaker diaphragm according to claim 2,
wherein a peeling strength is provided between the two sheet-forming bodies.
5. The speaker diaphragm according to claim 4,
wherein a space of the another sheet-forming body is smaller than a space of the one sheet-forming body.
6. The speaker diaphragm according to claim 5,
wherein a direction of the fiber in the boundary other than the entangled portion is a direction along the boundary, and a direction of the fiber in the entangled portion is a direction from the another sheet-forming body to the one sheet-forming body.
7. The speaker diaphragm according to claim 6,
wherein a Young’s modulus of the another sheet-forming body is larger than a Young’s modulus of the one sheet-forming body.
8. The speaker diaphragm according to claim 6,
wherein the one sheet-forming body is a surface layer in the plurality of sheet-forming bodies, and
the one sheet-forming body has a uniform thickness over the entire area.
9. The speaker diaphragm according to claim 8,
wherein the another sheet-forming body adjacent to the one sheet-forming body has a uniform thickness over the entire area.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A disposable wearing article having a first surface facing the wearer’s body and a second surface facing a garment, said article comprising an adhesive tape fastener disposed to said second surface, said tape fastener having a free end zone and a fixed end zone opposed to each other in a longitudinal direction, said fixed end zone being secured to said second surface, said tape fastener being disposed to said wearing article in a folded posture, said tape fastener being unfolded in a direction from said fixed end zone toward said free end zone with said free end zone being held, and said tape fastener having an inner surface facing said second surface in an unfolded state and being partially coated with an adhesive, said disposable wearing article further comprising:
a first tape strip having said free end zone and a first end zone opposed to said free end zone in said longitudinal direction;
a second tape strip underlying said first tape strip so as to face said second surface and having said fixed end zone and a second end zone opposed to said fixed end zone and being connected to said first end zone of said first tape strip at said second end zone;
said first tape strip being coated on said inner surface with said adhesive so as to be releasably attached to said second tape strip underlying said first tape strip, said first end zone including an extension extending from said free end zone toward said first end zone beyond said second end zone of said second tape strip and releasably attached to said second surface; and
a region of said second tape strip in which an inner surface of said first tape strip is releasably attached to said second tape strip being not adhesively attached to said second surface opposed to said region so as to be released upwardly from said second surface.
2. The disposable wearing article according to claim 1, wherein a third tape strip is interposed between said second tape strip and said second surface and secured over its substantially full length to said second surface and wherein said fixed end zone is attached to said second surface with said third tape strip therebetween.
3. The disposable wearing article according to claim 1, wherein said extension of said first tape strip is releasably attached to said second surface with said third tape strip therebetween.
4. The disposable wearing article according to claim 1, wherein said disposable wearing article is a pants-type disposable diaper having a front waist region, a rear waist region and a crotch region extending between these waist regions, said crotch region is provided with an absorbent core, said front and rear waist regions being connected together along respective transversely opposite side edge portions so as to form a waist-hole and a pair of leg-holes and wherein said fixed end zone of said second tape strip is adhesively attached to said second surface in each of said side edge portions of at least one of said front or rear waist region so that the longitudinal direction of said second tape strip is parallel to a waist-surrounding direction of said diaper.
5. The disposable wearing article according to claim 4, wherein said disposable diaper has flaps formed by a sheet material extending outwardly beyond a peripheral edge of said core and said fixed end zone of each said second tape strip is adhesively attached to said second surface in each of said flaps.
6. The disposable wearing article according to claim 1, wherein a portion of said second surface under each of said tape fastener in a folded posture or a laminated sheet portion including said portion of said second surface and sheet members separately provided in addition to said portion which are overlaid and joined together has a flexural stiffness of (0.03-0.7)104Nm2m.
