Water-disintegrable sheet and method for manufacturing water-disintegrable sheet
11272824 · 2022-03-15 · ·

A water-disintegrable sheet in which a base paper sheet is impregnated with an aqueous agent is provided. The base paper sheet has a weight per unit area of 30 to 150 gsm and includes a water-soluble binder and cellulose nanofibers. The aqueous agent includes a cross-linking agent which cross-links with a water-soluble binder. In the base paper sheet, content of the water-soluble binder and content of the cellulose nanofibers gradually increase from inside toward outside of the base paper sheet in a thickness direction. When a wear resistance test is performed three times using a Gakushin type fastness rubbing tester with a PP band as a rubbing finger and an average of measured values for the three times is calculated for each of a MD direction and a CD direction, each average value is at least 40.

Hydrolytic sheet and method for manufacturing hydrolytic sheet

A hydrolytic sheet is obtained by impregnating a base paper sheet with an aqueous agent. The base paper sheet has a weight per unit area of 30 to 150 gsm and includes a water-soluble binder. The aqueous agent includes a cross-linking agent which cross-links with the water-soluble binder and cellulose nanofiber.
