Abstract
Disclosed is a water-disintegratable sheet including water-dispersible fibers and microfibrillated cellulose. The water-dispersible fibers are hydroentangled about each other to provide high fiber density regions and low fiber density regions. The hydroentangled water-dispersible fibers are bonded to each other through a hydrogen bonding power of the microfibrillated cellulose.
