Title:

POLYOLEFIN FIBER FOR REINFORCING CEMENT

Document Type and Number:

Japanese Patent JP3406664

Kind Code:

B2

Abstract:

PURPOSE: To provide a polyolefin fiber for reinforcing cements, little in a floating phenomenon even when dispersed in fresh water or in water for a long time.
CONSTITUTION: Polypropylene or poly 4-methylpentene-1 is mixed with 1-35wt.% of a metal oxide such as zinc oxide and subsequently melt-spun so that the metal oxide is located on the surface of the produced fiber, thus providing a homogeneous fiber or conjugated fiber having a specific gravity of 1.00-2.30, which is useful as a polyolefin fiber for reinforcing cements.
