Abstract

The present invention relates to a polyolefin pellet for preparing a fiber, and a fiber comprising the same. According to the present invention, provided is a polyolefin, which exhibits a high molecular weight range and a narrow molecular weight distribution and in which the formation of a gel deteriorating the quality of a fiber is reduced. Therefore, by using the polyolefin pellet, the present invention exhibits a molecular weight, a density and a narrow molecular weight distribution, which are equivalent to those of conventional polyolefin, but has high tenacity and an excellent drawing characteristic and can be highly oriented because gel formation is reduced, and therefore, the present invention can be applied to various industrial products due to a high draw ratio and crystallinity during a multifilament operation using the same.
