  Abstract

The poor compatibility between a Fe2O3 pigment and a blend of ultrahigh molecular weight polyethylene (UHMWPE)/polyolefin (PO) can result in low spinnability and poor mechanical properties of the resulting fiber. This study modifies the surface of a Fe2O3 pigment with a titanate coupling agent for dope dyeing melt-spun UHMWPE fiber. The effects of the coupling agent dose, reaction temperature and reaction time on the surface properties of the pigments are investigated. In addition, the characteristics of the UHMWPE blend and colored fibers (by dope dyeing with modified and unmodified Fe2O3 pigments) are compared. Notably, 3 wt.% coupling agent in regard to the pigments mass, a coupling agent to toluene mass ratio of 1:5, a reaction time of 30 min, and a reaction temperature of 80
