PRODUCTION OF RAW YARN FOR LEADER FOR FLY-FISHING |
摘要 |
PROBLEM TO BE SOLVED: To provide a process for producing a raw yarn for a leader for fly-fishing in high yield preventing the formation of an unstable part (neck) having a diameter thinner than the average line diameter of the tippet part at the transition part from a tapered part to the tipped part. SOLUTION: A raw yarn for a leader for fly-fishing composed of a butt part, a tapered part and a tippet part is produced by extruding a vinylidene fluoride resin monofilament through a spinning nozzle and cooling the monofilament by passing through a refrigeration medium in a cooling bath while varying both the extrusion rate and the take-up speed according to the diameter of the butt part and the tippet part. |
