Engineering a Fishing Line Revolution
In 1966, Mr. Ishii, a Chemical Engineer employed in the researcher division of Kureha, Japan, and Mr. Yoshida, and avid angler working in the Patent Department of Kureha, Japan, noticed that the attributes of Fluorocarbon were ideally suited to fishing line. The men saw that Fluorocarbon is less absorbant than nylon monofilament, impervious to UV rays, high-density and nearly invisible underwater. They knew early on...Fluorocarbon would revolutionize fishing line! And so the two men applied for a patent, which was granted and registered in 1969.
That year Kureha launched its Fluorocarbon Development Project. The committee was staffed with 40 Kureha employees but its primary purpose was to develop Fluorocarbon film for capacitors and to formulate Fluorocarbon enhanced exterior paint, in order to harness its chemical and UV ray resistance. Development of Fluorocarbon fishing line suffered budget losses at the hands of these other priorities, but Mr. Ishii, now an avid angler himself, and Mr. Yoshida were passionate and determined. The two men continued to focus on line development but had use only of older equipment which failed and had to be repaired many times before they could continue the process.
Kureha had mastered the process of extracting only the highest-caliber Fluorocarbon crystal from which the leader and line resin is derived; it would be several years, however, before Kureha succeeded in extruding the resin properly to create Fluorocarbon fishing line that met the performance traits desired. Many engineers employed by Kureha contributed significantly to the development process but it was Mr. Hiroshi Sato and Mr. Ohhira who picked up for Mr.Ishii and Mr.Yoshida to tenaciously pursue the development of Fluorocarbon fishing line of only the highest standards. Several successful experiments and tests were conducted along the way to verify the properties and benefits of Fluorocarbon vs. other fishing line products. These milestones kept the project alive and won the support of executive management.
Finally, once quality standards had been established, once the production technology and equipment had been perfected and put in place in a new factory large enough to support the extrusion process, Kureha introduced Seaguar Fluorocarbon Fishing Line to attendees of the 1972 Osaka Fishing Tackle Exhibition. Anglers were impressed by its invisibility and high-density which allows the line to sink faster, providing less suspicious and more immediate access to the strike zone.
Since then, Seaguar has advanced many steps to arrive at the product we're so proud to present today. The first puzzle provided by the 1970's version of Fluorocarbon fishing line was how to improve knot strength for Leader and Tippet applications. Seaguar engineers decided it would be quite difficult to improve on knot strength without changing the structure of the line and they did not want to compromise the benefits that had been achieved thus far. So, once again with Mr. Ohhira at the helm, Seaguar began to think about a revolutionary double structure line...comprised of two different resins but still resulting in a single structure, impossible to separate, made exlusively with 100% Seaguar produced Fluorocarbon resin and Seaguar managed extrusion processes, with all the same qualities of Seaguar's single structure line and more.
The only problem with the double structure concept was that the two resin formulation and structure made extrusion, a difficult process, much more difficult. It would not be until 1983, with the contribution of improved extrustion processes designed by Mr. Akiyama of Kureha, Japan, that Seaguar introduced Seaguar Ace Leader, recognized as Red Label in the U.S. market today. Today's Double Structure Technology products include Seagar's Red Label, Grand Max, Grand Max FX and Fluoro Premier brand Leaders and Tippets. Seaguar's Double Structure Technology provides a core 100% Seaguar Fluorocarbon resin that is harder, and an outer 100% Seaguar Fluorocarbon resin that is softer for a better grip effect when knotted.
The next focus in Fluorocarbon advancement was improvement in abrasion resistance. Again, Mr. Ohhira and his team championed the task and, with the expertise earned through so many previous years spent developing formulations, succeeded in creating a new Fluorocarbon resin that would maintain current performance expectations yet better withstand heavy cover. The result? Our new AbrazX line, designed for heavy cover and lab tested to be twice as abrasion resistant as competing Fluorocarbon brands.
Seaguar continues to develop and perfect the art of 100% Fluorocarbon Leader, Tippets and Main Line. This Fall we introduce TATSU, a best in class, tournament quality main line that utilizes our Double Structure Technology - the first and only Double Structure Main Line on the market for ultimate strength, ultimate sensitivity and undefeatable performance. ::
