Abstract

The thermal conductivity of highly oriented ultra-high-molecular-weight polyethylenes (UHMWPEs), such as fiber and film, are known to increase as the drawing ratio increases in the direction of the orientation axis. UHMWPE fibers were prepared by gel spinning and dry heat stretching methods. To increase the drawing ratio, a certain amount of high-density polyethylene (HDPE) was added to the dope. The addition of HDPE enhanced the drawing ratio, and the resultant tensile strength and modulus of the UHMWPE fibers also increased. The HDPE-added fibers showed a lower degree of crystallinity but a higher drawing ratio compared to those of the neat UHMWPE fibers. Therefore, HDPE was an effective additive for producing highly drawn UHMWPE fibers as potential fibrous heat-release materials.
