(57) [Abstract] [PROBLEMS] To provide a method for producing a paper or non-woven fabric having a binder concentration gradient in the thickness direction of a sheet by controlling the distribution of binder components in the thickness direction of the sheet. To provide. SOLUTION: The binder is applied to a web having a compression recovery rate of 30% or more, the web is compressed in the thickness direction so that the compression ratio is 0.2 or more, and then decompressed to obtain the above web. A method for producing paper or non-woven fabric, which comprises forming a concentration gradient of the binder in the inside thickness direction. |
