Abstract
The invention is contemplated for providing polyethylene-based fibers in which elution of metal from polyethylene is suppressed as much as possible. The invention relates to polyethylene-based fibers, composed of at least one kind of polyethylene resin, in which a total of content of metal elements such as Na, K, Ca, Fe, Cu, Mg, Mn, Li, Al, Cr, Ni and Zn contained inside the fibers is 40 ppm or less. Moreover, the invention relates to a nonwoven fabric using the polyethylene-based fibers.
