Estimating the term…
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%.
A nonwoven fabric comprised of fibers comprising a thermoplastic resin, wherein an average yarn single fineness of the fibers is 0.7 dtex or more and 4.0 dtex or less, the fibers contain a fatty acid amide in an amount of 0.01% by mass or greater and 1.5% by mass or less with respect to a total fiber mass, and a fatty acid amide coverage on a surface of the fibers is 20% or greater and 90% or less, wherein the thermoplastic resin is a polyolefin and a birefringence Δn of the fibers is 0.015 or greater and 0.029 or less.
