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×(A)1/2/T)+(M×(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.
Claims2
An antibacterial, biodegradable extracting container having a filtering surface formed from a water-permeable sheet selected from woven fabrics,
- wherein fibers from which the water-permeable sheet is formed comprises, as a principle component, an antibacterial, biodegradable polyactate polymer, and have a thickness of 1 to 100 dtex, and
- the water-permeable fabric sheet, from which the filtering surface is formed, has a cover factor K of 1600 to 6400 determined in accordance with the following equation;
- K=(N×(A)1/2/T)+(M×(B)1/2/S)
- wherein, N represents a warp density (yarn/10 cm), M represents a weft density (yarn/10 cm), A represents a thickness (dtex) of the warp yarns, B represents a thickness (dtex) of the weft yarns, T represents a specific gravity of the warp yarn and S represents a specific gravity of the weft yarns.
