摘要： An object of the present invention is to provide a spongelike structure or a powder having fibers three-dimensionally arranged therein with high dispersibility, whose apparent density can be designed depending on the purpose or utility, as well as a process producing them. A fiber dispersion in which fibers having a number mean diameter in a predetermined range are dispersed in a dispersion medium, and this fiber dispersion is dried to remove the dispersion medium, thereby, a spongelike structure and a powder are produced.

摘要： An abrasive cloth which comprises an article in a sheet form having, in at least a part thereof, nano-fibers comprising a thermoplastic polymer and having a number average single fiber fineness of 1 × 10-8 to 2 × 10-4 dtex wherein the sum of single fiber fineness percentages (which is defined in the specification) of a single fiber fineness of 1 × 10-8 to 2 × 10-4 dtex is the range of 60 % or more, and exhibits a stress at 10 % elongation in a longitudinal direction of 5 to 200 N/cm-width; and a method for preparing a nano-fiber structure, which comprises providing a nano-fiber dispersion having a dispersant and, dispersed therein, nano-fibers comprising a thermoplastic polymer and having a number average diameter of 1 to 500 nm, attaching the dispersion to a support, and then removing said dispersant. The above abrasive cloth is excellent in polishing characteristics, and the above method allows the preparation of a nano-fiber structure wherein nano-fibers form a composite with the support.
