Abstract
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).sup.1/2 /T)+(M.times.(B).sup.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.
