摘要： A nonwoven fabric having a surface concavo-convex structure, and a molded member and a wiping cloth that use the nonwoven fabric are provided. The nonwoven fabric having a surface concavo-convex structure is formed by pressing a planar element having a plurality of apertures against at least one surface of a nonwoven fabric that has been formed by passing hot air through a web including heat adhesive fibers so as to heat-bond interlacing points between the fibers. The pressing process is performed in a state where the nonwoven fabric retains heat in a degree that does not further promote the heat bonding. The nonwoven fabric having a surface concavo-convex structure is soft and exhibits high strength and sufficient resistance against stress.

The composite fibers can be produced by extruding a polypropylene and a polymer mainly comprising a polyethylene through a spinneret for composite spinning to form unstretched composite filaments having such structure as mentioned above, stretching the unstretched composite filaments at a temperature of higher than 90.degree. C., but lower than 130.degree. C. at a stretching ratio of 0.60 to 0.85 time the maximum stretching ratio, cooling the stretched filaments to a temperature lower than a preheating temperature, subjecting the filaments to a crimping treatment, and subjecting the filaments to an annealing at a temperature of higher than 80.degree.
