  • Publication number: 20240115432
    Abstract: The present invention provides: a nonwoven fabric which gives a sufficiently soft touch when touched by a human hand, while being suppressed in slipperiness between nonwoven fabrics during the production process of a product such as a sanitary material; and a method for producing a nonwoven fabric. One embodiment of the present invention provides a nonwoven fabric which is formed of fibers containing a thermoplastic resin, wherein: the average single fiber fineness of the fibers is 0.7 dtex to 4.0 dtex; the fibers contain 0.01% by mass to 1.5% by mass of a fatty acid amide relative to the total mass of the fibers; and the coverage of the surfaces of the fibers by the fatty acid amide is from 20% to 90%.

  • Patent number: 10655255
    Abstract: An object of the present invention is to provide a nonwoven fabric having high tensile strength and high tear strength. The laminate nonwoven fabric of the present invention is a laminated nonwoven fabric obtained by thermally press-contacting a thermoplastic continuous fiber layer as an outer layer with both surfaces of an interlayer, wherein the ratio (F1/F2) between the average oblateness (F1) of the thermoplastic continuous fiber present on the surface side and the average oblateness (F2) of the thermoplastic continuous fiber present on the inner side is 1.20 or more.
