| 摘要 |
The invention concerns a nonwoven fabric made up of filaments comprised of a polylactic acid-based polymer, wherein the polylactic acid-based polymer is a polymer selected from copolymers of D-lactic acid and L-lactic acid, copolymers of D-lactic acid and hydroxy-carboxylic acid, and copolymers of L-lactic acid and hydroxy-carboxylic acid, said polymer having a melting point of 100°C or more, or being a blend of such polymers having a melting point of 100°C or more. The constituent filaments of the nonwoven fabric are partially fusion bonded with heat and pressure by embossing or ultrasonic fusion, wherein said fusion bonding is present in spottedly configured individual fusion bonded areas. The invention also concerns a method of fabricating a nonwoven fabric made up of filaments comprised of a polylactic acid-based polymer. |
