Abstract

Disclosed is a liquid absorbent sheet for absorbing and retaining liquid. The liquid absorbent sheet is a single nonwoven fabric in which a liquid permeable layer (5) and a liquid retaining layer (7) are inseparably but distinguishably formed. The liquid permeable layer (5) is exposed externally on one side of the nonwoven fabric. The liquid retaining layer (7) lies beneath the liquid permeable layer (5) for absorbing and retaining liquid. The liquid permeable layer (5) contains at least 70% synthetic resin fibers by weight. The liquid retaining layer (7) contains at least 70% cellulosic fibers by weight. Constituent 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.

Description

technical field [0001] The present invention relates to a liquid-absorbent sheet for absorbing liquid droplets exuded from foodstuffs or for other liquid-absorbing applications. Background technique [0002] Liquid-absorbent sheets are used for various purposes. A general liquid-absorbent sheet contains cellulose-based fibers such as pulp and rayon, and can retain moisture between the fibers due to the hydrophilic force of the fibers. Preferably, the liquid-absorbing sheet has another layer spaced from the liquid-discharging portion on its liquid-supplying surface so that the liquid absorbed by the liquid-absorbing sheet hardly comes into direct contact with the liquid-discharging portion. [0003] The following Patent Documents 1 to 3 disclose liquid-absorbent sheets that are placed in food pans and the like to absorb liquid droplets such as blood discharged from fresh foods such as meat and fresh fish. [0004] In the liquid-absorbent sheets described in Patent Documents...
