Monofilament and Multifilament Fishing Lines


Fishing line is a line made of twisted fibers or threads, generally attached to the sinker, float and hook. There are several types of fishing lines which have their unique features. Two of the main types are monofilament and multifilament lines. The lines differ mainly by the type of material used, length and weight of the fiber. The size of the line is expressed by its diameter. It is also preferred to have additional features like resistance to ultraviolet rays, stretch and visibility in the lines.


Monofilament fishing line is made of a single fiber or plastic. They have been used for a long time and are one of the oldest types of lines. These are made of nylon material. Sometimes nylon mixed with other materials (also known as copolymer) are also used. It helps to increase certain features such as breaking stain and softness. Monofilament lines are the most popular among all types of lines. These lines come in a variety of qualities but most of them are still cheaper than other types of lines. A quality monofilament line has consistent strength and color. It is normally somewhat transparent or rather translucent with tinges of various colors. The color of the line is also controlled by adding chemicals. The main advantage of monofilament line is that it can be stretched under the load. This line is used in wide variety of fishing applications but it cannot be used under deep water as it absorbs more water, thus resulting in losing the knots. It also has the disadvantage of causing death to fishes, birds and other animals, as they cannot be seen under water, thus causing environmental problems.


Multifilament fishing lines are the newest form of lines. These are made of different kinds of fibers. Earlier, cotton or silk were used as fibers, but at present polyester or polymers are used for making the fiber. The line in the case of multifiament is very thin for its strength. They are costlier than monofilament equivalents and stretch a lot lesser than monofilmanets. Multifilament fishing lines work best on bait casting reels and can be used under deep water. The fibers in multifilament lines are not braided, instead they are twisted, cabled or stuck together.

Monofilament is still the most common type of fishing line used by fisherman especially due to the cost. Normally, a multifilament costs four times of the equivalent monofilament and tying knots is also more difficult with multifilament ones. So, most fisherman normally abstain from purchasing it. But it has been seen that the use of multifilament fishing lines is increasing in recent times especially for deep water fishing and due to environmental benefits.
