Stretch nonwoven fabric and tapes

To produce a nonwoven fabric comprising a conjugated fiber comprising a plurality of resins which are different in thermal shrinkage and form a phase separation structure. In the nonwoven fabric, the conjugated fibers are arranged in a direction approximately parallel to a surface direction of the nonwoven fabric and crimped. In addition, the conjugated fibers have an average curvature radius of fiber crimp of 20 to 200 [mu]m and the crimps are distributed approximately uniformly in a thickness direction of the nonwoven fabric. The nonwoven fabric is substantially free from an adhesive agent. In the nonwoven fabric, each fiber is substantially not melt-bonded to another. The conjugated fiber may comprise a polyalkylene arylate-series resin and a modified polyalkylene arylate-series resin and have a side-by-side or eccentric sheath-core form. Since the bimetal form conjugated fibers having specific crimps are appropriately entangled with each other, the nonwoven fabric has a high stretchability and is easily torn by hand, without using scissors. The nonwoven fabric is suitable for a tape such as a bandage or a supporter.
