| abstract |
The present invention relates to a novel bicomponent fiber, a nonwoven fabric comprising the novel bicomponent fiber, and a physiological article made therefrom. The bicomponent fiber contains a polyethylene-based resin that forms at least a portion of the fiber surface continuously in the longitudinal direction and also has a comonomer partition coefficient of at least about 45, a recrystallization temperature of 85 ° C. to 110 ° C., about 15 at 0.1 rad / sec. And polyethylene based resins having a tan delta value of from 50 to 50, and a composite viscosity of 1400 Pa.sec or less at 0.1 rad / sec. The nonwoven fabric comprising the novel bicomponent fiber according to the present invention is not only excellent in flexibility, but also high in strength and high in throughput, so that it can be produced on a commercial scale with low energy and low energy. |
