Abstract: PURPOSE:To enable smooth separation and have no fear of damage at the separating time by providing a fastening tape with a nonadhesive face, and reducing the area of an adhesive face per unit area over the width direction of the fastening tape, toward an end part in the vicinity of the fastening tape end part on the grip part side. CONSTITUTION:A fastening tape 10 has a pentagonal nonadhesive face 18, and the nonadhesive face 18 forms a grip part 12. Since the nonadhesive face 18 is pentagonal, the area of an adhesive face 15 per unit area over the width direction of the fastening tape 10 is reduced toward a fastening tape end part 11 in the vicinity of the end part 11 on the grip part 12 side, that is, the adhesive face 15 is gradually increased toward both sides from the nearly center part in the width direction of the fastening tape 10. The fastening tape 10 can be thereby separated smoothly, and there is no fear of damaging an adhered place at the separating time.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a three-dimensionally formed nonwoven fabric by which the fluffing is suppressed.
SOLUTION: The method for producing the three-dimensionally formed nonwoven fabric includes embossing a fiber web containing a thermally extensible fiber extending the length by heating to form many bound parts in the fiber web, extending the extensible fiber positioned among the bound parts by blowing hot air to form many convex parts among the bound parts, and passing the resultant web between a pair of flat rolls arranged at a prescribed clearance to carry out the smoothing of the convex parts. When the clearance between the flat rolls is H, and the thickness of the nonwoven fabric before being subjected to the smoothing is T, H/T is set to 0.7-1.0. The temperature of the flat roll on the side of contacting the convex parts is set to a temperature of from -10 to +50°C based on the melting point of the resin constituting the thermally extendable fiber.
