ABSTRACT:
Monofils based on polyethylene-2,6-naphthalate are described containing 60 to 99.9 wt-percent polyethylene-2,6-naphthalate, 0.1 to 10 wt-percent of one or more liquid crystalline polymers, 0 to 15 wt-percent polybutylene terephthalate and 0 to 3 wt-percent of an inhibitor, as well as optionally additional additives, as is a melt-spinning process for producing the same. The filaments are characterized by good mechanical properties, in particular improved knot strength and resistance to hydrolysis. They are suited primarily for making screens, filters and reinforcing inlays.
