Multifilament line, also referred to asThe Super Lines, is a type of fishing line.[1] It is abraided line which is made up ofultra-high-molecular-weight polyethylene (UHMWPE), a specialtypolyethylenepolymer that makes an extremely thin line for its strength. By weight, UHMWPE strands are five to ten times sturdier thansteel. Multifilament line is similar to braideddacron in terms of sensitivity but adiameter about one-third that of the ubiquitousnylonmonofilament line.[2]
Multifilament works best on conventional andbaitcasting reels. Onspinning and spincasting reels, the line's limpness can make sure for awkward manipulation, as it does not "spring" off the reel likemonofilament. Consequently, knot-tying is more difficult with multifilaments. Certain knots work better with superline, like thepalomar knot. Applying a type of super glue will help to prevent other types of knots from slipping.
This type offishing line is expensive, sometimes four times the cost of equivalent monofilament. This can become a considerable expense, especially considering that the line is so thin that one needs more of it to fill a reel spool. Sometimes, a backing of monofilament or other line is used under the braided line on the spool.[3]
