Moisture absorptive-and-desorptive member and product using the same

Abstract

The present invention is directed to a moisture absorptive-and-desorptive member capable of effectively removing moisture from air, comprising a substrate having a moisture absorptive-and-desorptive polymer disposed thereon. The moisture absorptive-and-desorptive member may sometimes be subjected to a pleating processing in order to increase surface area and improve moisture absorptive-and-desorptive properties. However, when the member has high air permeability, the pleats are often deformed or distorted. As a solution to the problems, the present invention provides a moisture absorptive-and-desorptive member comprising a base paper having an ISO air permeability of
