<p>An antibacterial, biodegradable extracting container has a filtering surface formed from a water-permeable woven or knitted fabric formed from fibers comprising, as a principal component, an antibacterial, biodegradable polylactate polymer, and having a thickness of 1 to 100 dtex, wherein, preferably, the filtering surface is formed from the woven fabric having a cover factor K of 1600 to 6400, determined in accordance the following equation: K = (N .times. (A)1/2/T) + (M .times. (B)1/2/S) wherein, N = warp density (yarns/10 cm), M = weft density (yarns/10 cm), A = thickness (dtex) of the warp yarns, B = thickness (dtex) of the weft yarns, T = specific gravity of the warp yarns and S = specific gravity of the weft yarns.</p> |
