Title:
INORGANIC FIBER STRUCTURE AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2010/082603
Kind Code:
A1
Abstract:
Disclosed is an inorganic fiber structure which comprises inorganic nanofibers having an average fiber diameter of 3 μm or less and has a void ratio of 90% or more, and in which the inorganic fibers in the whole body including interior portions thereof are adhered together by means of an inorganic adhesive agent. Also disclosed is a process for producing an inorganic fiber structure, which comprises the following steps (i) to (iii): (i) spinning inorganic fibers from a spinning-purpose inorganic sol solution containing a compound mainly composed of an inorganic component by means of an electrostatic spinning technique; (ii) irradiating the inorganic fibers with an ion having an opposite polarity to those of the inorganic fibers to accumulate the inorganic fibers, thereby producing an inorganic fiber assembly; and (iii) applying an adhesion-purpose inorganic sol solution containing a compound mainly composed of an inorganic component to the whole body including interior portions of the inorganic fiber assembly and removing an excess portion of the adhesion-purpose inorganic sol solution from the inorganic fiber assembly by means of air blow, thereby producing the inorganic fiber structure in which the fibers in the whole body including interior portions thereof are adhered together by means of an inorganic adhesive agent.
