VOLATILE SUBSTANCE-VOLATILIZATION ADJUSTING MATERIAL, VOLATILE SUBSTANCE-VOLATILIZATION ADJUSTING FILTER MEDIUM, VOLATILE SUBSTANCE-VOLATILIZATION CONTROLLING METHOD AND VOLATILE SUBSTANCE-VOLATILIZATION CONTROLLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a volatile substance-volatilization adjusting material which permits release of a volatile substance only in a prescribed time period by controlling the degree of release of the volatile substance, and also to provide a volatile substance-volatilization adjusting filter medium, a volatile substance-volatilization controlling method and a volatile substance-volatilization controlling device.

SOLUTION: The volatile substance-volatilization adjusting material is made by drying a mixed solution in which cyclodextrin including a volatile substance is mixed with water. The volatile substance-volatilization adjusting filter medium carries the volatile substance-volatilization adjusting material on the filter medium. Furthermore, the volatilization controlling method of a volatile substance alternately puts the volatile substance-volatilization adjusting material into a water absorbing condition where it has absorbed water and a dry condition where water is removed by drying. The volatile substance-volatilization controlling device has a water supplying means to supply water to the volatile substance-volatilization adjusting material to make it absorb water and a drying means to dry the volatile substance-volatilization adjusting material which has absorbed water.
