    摘要： Melt-adhesive composite fibers; non-woven fabrics from the composite fibers fused at intersectional points of the fibers; and surface materials for medical supplies such as sanitary napkins and paper diapers are disclosed. The composite fibers have a polypropylene as the first component and a polymer mainly composed of a polyethylene as the second component which is continuously present on at least a part of the fiber surface in the lengthwise direction of the fiber; have three-dimensional crimps of 4 to 16/inch; have a filamentary denier of 1.0 to 2.0, and have an apparent cut length of 20 to 40 mm. 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. C., but lower than 120.degree. C.

    摘要： A functional sheet is described, in which a modifier is uniformly and exactly scattered and deposited such that sites where the modifier is deposited and sites where no modifier is deposited are clearly discriminated. The functional sheet is obtained by masking a surface of a sheet containing at least one fibrous layer on the surface by a planar object having a plurality of openings, applying a solution of a modifier from a side of the planar object, and allowing the modifier to deposit onto a whole surface of the sheet exposed to the openings of the planar object, and a functional sheet in which sites where the modifier is deposited form projections and sites where no modifier is deposited form plains in a surface fibrous layer of the functional sheet.

    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.
