To solve such problems that water-absorbing/deodorizing functions which are lowest necessary conditions for underwear are almost impossible to be given to conventional petroleum-based fiber products and complete elimination of "sick house syndrome" from petroleum-based wallpaper and sheets for a floor and a ceiling for which chemicals are used is impossible.

Clothing, wallpaper, and construction materials for the floor and ceiling are formed by giving negative ion-emitting properties to a nonwoven fabric of bamboo, wherein the nonwoven fabric of the bamboo has water-absorbing, moisture-releasing, deodorizing, and antimicrobial characteristics and functions which are the lowest necessary conditions for the underwear and an indoor environment of a house. Thus, effects of the various characteristics and functions of the fabric are remarkably increased, and efficacy of raising immunological competence, activating metabolism, promoting recovery from exhaustion, and stabilizing mind is produced. Further, the "sick house syndrome" is completely eliminated as a matter of course.
