Dehumidifying element, dehumidifying device including dehumidifying element, and method of manufacturing dehumidifying element

A dehumidifying element includes a plurality of sheets that have moisture adsorption and desorption properties and that are stacked on top of each another. At least some of the sheets each have an irregular shape. The sheets each contain a hygroscopic agent having properties of a re-moistening-type glue that exhibits adherence when adsorbing moisture and that solidifies when being dried. The sheets are bonded to each other by the hygroscopic agent.

Composite and methods of making same

Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.
