PURPOSE:To obtain a biodegradable filament non-woven fabric excellent in mechanical strength and flexibility by partially hot-adhering the filaments of a filament web comprising a specific aliphatic polyester (co)polymer to each other. CONSTITUTION:This biodegradable filament non-woven fabric is produced by meltspinning a biodegradable thermoplastic aliphatic polyester (co)polymer comprising polyethylene succinate, polybutylene succinate or the copolymer of 0-35wt.% of the polyethylene succinate with 100-65wt.% of the polybutylene succinate, taking out the spun fibers with an air sucker, depositing the taken fibers on a moving catching surface to form a web, and subsequently subjecting the web to a thermal embossing treatment to partially adhere the filaments constituting the web to each other. |
