摘要： A high moisture absorbent nonwoven fabric structure comprising a moisture absorbing layer mainly consisting of high moisture absorbent fibers, and surface sheets sandwiching the moisture absorbing layer to constitute a three-layer structure. The high moisture absorbent fibers gel on the surfaces thereof by absorbing water and/or moisture to develop a self-bonding force. The high moisture absorbent nonwoven fabric has an absorptivity, after five hours at 20° C. and relative humidity of 65%, of at least 20 wt. %, at least one of the surface sheets has breathability, and the self-bonding force of high moisture absorbent fibers ensures bonding between fibers in the moisture absorbing layer and between the moisture absorbing layer and the surface sheets. The high moisture absorbent nonwoven fabric structure, which is high in hygroscopicity, applicable to a small space, and easily recyclable by heat treating nonwoven fabrics after moisture absorbed, can be used in a variety of fields such as desiccants and dehumidifying agents.
