Liquid absorbent sheet and method for manufacturing the same

A liquid absorbent sheet for absorbing and retaining liquid, the liquid absorbent sheet being a single nonwoven fabric, comprising:

• a liquid permeable layer;
• and
• a liquid retaining layer,
• wherein the liquid permeable layer and the liquid retaining layer are inseparably but distinguishably formed, the liquid permeable layer being exposed externally on one side of the nonwoven fabric, the liquid retaining layer lying beneath the liquid permeable layer for absorbing and retaining liquid,
• the liquid permeable layer contains at least 70% synthetic resin fibers by weight, and the liquid retaining layer contains at least 70% cellulosic fibers by weight,
• the fibers of the nonwoven fabric are bonded together by an adhesive force of a binder and/or a bonding force caused by fusion of the synthetic resin fibers.
