DEW CONDENSATION PREVENTIVE SHEET MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a dew condensation preventive sheet member, which can surely prevent or reduce the development of dew condensation. SOLUTION: The dew condensation preventive sheet member 10 is laminatingly made of a layer 4 including moisture absorbing and desorbing material 4a and a lower vapor permeable layer 6 under the condition that the moisture absorbing and desorbing material 4a is a higher water absorbing polymer, which is supported in a fibrous sheet together with a hydratable microfibril obtained from cellulose or cellulose derivative.
