DuPont made public in 1938 that their company had invented nylon. [1] This new invention was the first synthetic fiber, fabrics that are commonly used in textiles today. [2] In 1939, DuPont began marketing nylon monofilament fishing lines; however, braided Dacron lines remained the most used and popular fishing line for the next two decades, as early monofilament line was very stiff or "wiry ...
Fishing line with hooks attached. A fishing line is any flexible, high-tensile cord used in angling to tether and pull in fish, in conjunction with at least one hook.Fishing lines are usually pulled by and stored in a reel, but can also be retrieved by hand, with a fixed attachment to the end of a rod, or via a motorized trolling outrigger.
The braided line is visible underwater as compared to other lines. Due to this line's thin diameter, it can cause scratches and cuts on the angler's hands. [2] Braided fishing lines have a low resistance to abrasion, and sharp objects can easily cut braided lines. [3] Their actual breaking strength will commonly well exceed their pound-test ...
PVDF is used for specialty monofilament fishing lines, sold as fluorocarbon replacements for nylon monofilament. The surface is harder, so it is more resistant to abrasion and sharp fish teeth. Its refractive index is lower than nylon, which makes the line less discernible to fish eyes. It is also denser than nylon, making it sink faster ...
Multifilament line is similar to braided dacron in terms of sensitivity but a diameter about one-third that of the ubiquitous nylon monofilament line. [2] Multifilament works best on conventional and baitcasting reels. On spinning and spincasting reels, the line's limpness can make sure for awkward manipulation, as it does not "spring" off the ...
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.

One type of instrument used to get the abrasion rate and normalized abrasion rate is the abrasion scrub tester, which is made up of a mechanical arm, liquid pump, and programmable electronics. The machine draws the mechanical arm with attached brush (or sandpaper, sponge, etc.) over the surface of the material that is being tested.
