PROBLEM TO BE SOLVED: To obtain a safety net having sufficient mechanical excellent weather resistance and performances biodegradability by using aliphatic polyester-based fibers (preferably spun dyed fibers) which have a melting point of a specific temperature or higher and preferably contain lactic acid as a main component and a multi-functional phosphorus compound. SOLUTION: This safety net comprises fibers consisting mainly of an aliphatic polyester having a melting point of >=130 deg.C. The safety net is preferably obtained by doubling spun-dyed multi-filament yarns and then knitting the doubled yarns by means of a Raschel knitting machine or the like. The spun-dyed multi-filament yarns consist mainly of the aliphatic polyester having a melting point of >=130 deg.C, further contain a bifunctional phosphorus compound, such as dimethyl phenylphosphate, in an amount of 0.1-1.5%, have a breaking strength of >=4.5 CN/dtex, preferably >=5.0 CN/dtex, a breaking elongation of >=15%, preferably >=18%, and a fineness of 250-4,000 dtex, and comprise 200-500 filaments.
