Estimating the term…
A low-temperature regenerative type moisture absorbing element of fast moisture absorbing and releasing speed, capable of regenerating at 110.degree. C. or less and having a sufficiently high moisture absorbing and releasing performance in spite of small size is provided. A low-temperature regenerative type moisture absorbing element is mainly composed of high moisture absorbing and releasing polymeric compound with the content of salt type carboxyl group adjusted to a specific amount, and further comprises plural gas passages, of which regeneration temperature is 110.degree. C. or less. It is hence possible to provide a moisture absorbing element of small size, high efficiency, and energy-saving type, being excellent in moisture absorbing and releasing performance, and easily capable of removing absorbed moisture at low temperature which was impossible with the conventional moisture absorbing element. It can be applied not only in industrial and commercial uses, but also in household dehumidifying and drying applications, and may be employed in dehumidifying and drying applications of various gases.
An element for a regenerative moisture absorbing dehumidifying-and-drying apparatus comprising a woven fabric, nonwoven fabric, film or paper shaped to form plural gas passages, said woven fabric, nonwoven fabric, film or paper having a fibrous flock applied thereto, said fibrous flock comprising fibers of a high moisture absorbing and releasing polymeric compound containing from 2.5 to 10.0 meq/g of a carboxylic salt group and crosslinked by hydrazine or a derivative thereof, wherein absorbed moisture is removed from said element at a temperature of 110.degree. C. or less to regenerate said element.
