FIELD: chemistry.
SUBSTANCE: disclosed is a water-absorbent laminate including: a first fibrous layer comprising a first fibrous structure comprising first hydrophilic fibres; and a second fibrous layer comprising a second fibrous structure, including wet-heat-treated fibres in an amount greater than or equal to 80 wt. %, in which the surface of the first fibrous layer on the opposite side relative to the second fibrous layer has a water absorption rate of less than or equal to 10 s, determined in accordance with the drop method described in JIS L 1907. Also disclosed is a method of producing a water-absorbent laminar material.
EFFECT: water-absorbing laminar material can additionally include a third fibrous layer including a third fibrous structure comprising second hydrophilic fibres between the first fibrous layer and the second fibrous layer.
