摘要： A process of manufacturing inorganic nanofibers, without using an organic polymer, using a highly reactive metal alkoxide such as titanium alkoxide or zirconium alkoxide, in particular, a process in which inorganic nanofibers can be stably produced over a long period, is provided. It is a process of manufacturing inorganic nanofibers by electrospinning using a sol solution containing an inorganic component as a main component, characterized in that the sol solution contains a metal alkoxide having a high reactivity and a salt catalyst, and that the salt catalyst is an amine compound having an N—N bond, an N—O bond, an N—C═N bond, or an N—C═S bond.

摘要： A process for manufacturing organic fibers containing an inorganic component comprising the steps of: (1) preparing an inorganic spinnable sol solution; (2) mixing the inorganic spinnable sol solution, a solvent capable of dissolving the inorganic spinnable sol solution, and an organic polymer capable of being dissolved in the solvent to prepare a spinning solution; and (3) spinning the spinning solution to form the organic fibers containing an inorganic component composed of an inorganic gel and the organic polymer, is disclosed. The inorganic spinnable sol solution preferably has a weight average molecular weight of 10,000 or more, and the inorganic spinnable sol solution is preferably prepared from a material containing a metal alkoxide having an organic substituent. According to the process of the present invention, organic fibers containing an inorganic component having an improved mechanical strength can be produced by mixing an inorganic component into an organic component, and a nonwoven fabric containing the fibers can be provided.
