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