PERSPIRATION-ABSORBENT LOWER BEDDING HAVING MOISTURE- SENSITIVE DISPLAY SECTION

PROBLEM TO BE SOLVED: To absorb the perspiration emitted from a human body at the time of sleeping, and prevent a Futon (Japanese quilt and matters) from moistening by constituting a perspiration-absorbent lower bedding of a fiber base material containing a moisture- absorbent fiber, and a moisture-sensitive display section which is detachably engaged with the surface of the fiber base material. SOLUTION: This perspiration-absorbent lower bedding is constituted of a moisture- absorbent fiber, wherein a fiber base material obtained by immersing a polyester fiber in which the terminal group of polyester is glycol-modified in the solution of a perspiration-absorbing agent and performing a treatment at a temperature of 60 to 80 deg.C, is contained, and a moisture-sensitive display section. In this case, the detachable moisture-sensitive display section is formed on the surface of the fiber base material of the moisture-absorbent fiber by applying a moisture-sensitive substance using a water-base emulsion of an acrylic resin or a vinyl acetate resin, wherein a cobalt chloride, a cobalt bromide, a nickel chloride, a nickel bromide, or the like, wherein a discoloring due to the absorbency of humidity or moisture reversibly occurs, are blended. By this constitution, the perspiration emitted from a human body at the time of sleeping can be absorbed, and a Futon can be prevented from moistening.
