Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fiber laminate which can prevent deterioration of the adsorption capability by controlling the detachment of the adsorbent effectively, includes high dust-capturing efficiency, excellent gas permeability and small pressure loss and is suitable for filters and a filter for air cleaning which is composed of the fiber laminate and includes the excellent characteristics of the fiber laminate. SOLUTION: The fiber laminate is a fiber structure comprising at least a supporting fabric and a front layer. The supporting fabric is composed of a fiber of an average fiber diameter of ≥10 μm and retains a granular adsorbent within it. The front layer is a fiber structure composed of a fiber of an average fiber diameter of 10-1,000 nm. A filter for air cleaning using the fiber laminate is also provided. COPYRIGHT: (C)2009,JPO&INPIT
