PROBLEM TO BE SOLVED: To provide a biodegradable filament nonwoven fabric consisting of biodegradable filaments comprising a polylactic acid-based polymer that are almost completely degraded after use and are easily disposed, and being excellent in transparency, dimension stability and component extraction properties, and to provide a filter for food obtained by using the same.SOLUTION: The biodegradable filament nonwoven fabric comprises polylactic acid filaments that contain a polylactic acid-based polymer having a melting point of 150°C or more as a main component, have an average fiber diameter of 15-40 μm, a birefringence of 0.005-0.025 and a crystallinity of 30-50%, and has a basis weight of 10-30 g/m. The filter for food comprises the biodegradable filament nonwoven fabric. |
