More Information
Summary:The present invention relates to a new bicomponent fiber, a nonwoven fabric comprising said new bicomponent fiber and sanitary articles made therefrom. The bicomponent fiber contains a polyethylene-based resin forming at least part of the surface of the fiber longitudinally continuously and is characterized by a Co-monomer Distribution Constant greater than about 45, a recrystallization temperature between 85°C and 110°C, a tan delta value at 0.1 rad/sec from about 15 to 50, and a complex viscosity at 0.1 rad/second of 1400 Pa.sec or less. The nonwoven fabric comprising the new bicomponent fiber according to the instant invention are not only excellent in softness, but also high in strength, and can be produced in commercial volumes at lower costs due to higher thoughputs and requiring less energy.
