Abstract

PURPOSE: A low-melt-viscosity vinylidene fluoride resin with specific physical properties is melt extruded and oriented at a draft ratio satisfying a specific equation, thus producing filaments suitably used for fishing lines, strings and tennis guts because of its high Young's modulus.
CONSTITUTION: A vinylidene fluoride resin of 0.85W1.4, preferably 1W1.2l/g inherent viscosity and less than 0.45, preferably 0.35 Huggins constant (both of them are measured in dimethylacetamide at 30°C), preferably a resin containing more than 90wt% polyvinylidene fluoride, is melt extruded and oriented by drafting so that the equation (ηapp is melt viscosity, when the resin is extruded through a nozzle of 1mm diameter and 3mm thickness in a melt indexer; R is draft ratio). Then, the extruded polymer is forcibly cooled to lower than 80°C to give the objective filament.
