Title:
ABSORBENT PAPER, ITS PRODUCTION AND ABSORBING MATERIAL USING THE SAME
Document Type and Number:
Japanese Patent JP3457417
Kind Code:
B2
Abstract:
PURPOSE: To obtain absorbent paper having a large liquid-absorbing space, high liquid absorption-permeability and high liquid diffusivity, to obtain its producing method and to obtain an absorbing material high in liquid absorbency, slight in liquid leakage and giving a comfortable wear feeling due to extra-thin thickness.
CONSTITUTION: The objective absorbent paper is absorbent paper 11 containing bulky cellulosic fibers 12 and hydrophilic fine fibers 13 wherein the hydrophilic fine fibers 13 have a content in one face side in the absorbent paper 11 higher than the content in the other face side and the bulky cellulosic fibers 12 have 1.5-20mm average fiber length and intramolecular or intermolecular cross-linking or have ≥0.3mg/m fiber coarseness, and the hydrophilic fine fibers 13 have 0.01-0.2mg/m fiber coarseness and 0.5-1mm average fiber length. This invention also claims a producing method of the paper and an absorbing material using the paper.
