Abstract
An elongated cylindrical tensile article of one or more strands of monofilament core surrounded by porous polytetrafluoroethylene (PTFE) which may be optionally coated or die sized on the outer surface for smoothness and/or abrasion resistance. The core filaments thereof may optionally be coated with high-temperature resistant adhesive for increased adherence to the PTFE. The article is particularly useful for fly-casting lines for fishing. The density may be controlled to produce a floating or sinking flyline or portion thereof.
Claims17

- (a) a non-metallic tensile strength member core comprising at least one monofilament;
- and
- (b) a layer of porous polytetrafluoroethylene surrounding said tensile strength member;
- wherein at least a portion of the length of the layer of porous polytetrafluoroethylene is tapered.
