Abstract (en)
[origin: EP3318667A1] A nonwoven fabric including fibers that contain a polymer having a glass transition temperature of greater than or equal to 50°C as a main component, and having a vertical strength of greater than or equal to 1 N/5 cm per 1 g/m 2 , and by satisfying both of the following conditions (1) and (2), a nonwoven fabric having sufficient strength to be handled alone and including fibers that contain a polymer having a Tg of greater than or equal to 50°C as a main component without performing a post processing such as emboss processing, calender processing, or spunlace processing, and a method for producing the nonwoven fabric can be provided. (1) A density is 0.01 to 0.4 g/cm 3 . (2) A proportion of parts with a density exceeding 0.4 g/cm 3 is less than or equal to 3% in a cross section in a thickness direction.
