The Secret of Braided Line -- Dyneema

DYNEEMA

The two major representations of Fusion Line are Fire Line and Spider Wire. And the Fire Line is made of Dyneema fiber. What exactly is the Dyneema fiber? Simply speaking, it is made of polyethylene, PE in short. However, if it is made of ordinary polyethylene fiber, it is not qualified to be called Dyneema.

The Dyneema fiber is an ultra high tension textile fiber which is made by one of a kind of novel technique, called the Gel Spinning Technology method. At present, the main class is the SK-60. Dyneema SK-60 has strong strength and high Modulus, thus it has the special alternative name of HMPE. According to the studies, the SK-60 tensile strength is 30g/d, but the newer generation Dyneema fiber SK-71 intensity is 40g/d, 30% stronger than that of SK-60. Theoretically, what is the highest HMPE strength? The answer is 300g/d!

The specific gravity is only 0.98, the only fiber lighter than water among other high strength. It is water resistant, but at the same time its intensity is not reduced due to immersing. Therefore, Dyneema is especially qualified serve as the fishing line: It has excellent softness yet is able to bear high levels of friction, with no memory, no elonagation, and the ability to endure high temperature (melting point is at 152 degrees); moreover, it can tolerate high levels of UV ray and chemical concentrations. Meaning, it is a durable and a high quality product.

Spectra 2000 comprises of Spider Line fiber, its raw material is -- polyethylene, PE. Besides, fundamentally speaking, it is produced by the very same method as the fusion line. That is, except the difference on the surface of the fishing line after being processed in the factories, in reality, they are all the same inside.

The Secret of Braided Line -- Kevlar

KEVLAR

The Kevlar fiber is one kind includes Aromatic and Amide chemistry polymer (these two kind of elements are main factors of making high strength material). This type of fiber has the extremely high tensile strength with to bear the impact. The abruption or shear will be very difficult.

Moreover its flexibility is moderate, the low heat conductivity, chemical etching bearing, the low hot shrinkage, incombustible and so on advantage. Therefore it makes each kind anti-pulls the wire rope (e.g. mountaineering rope), the protection material (e.g. armored clothing), the wear-resisting material (for example tire inner layer) as a good material.

To fishing, the Kevlar textile fiber twists one by every 134 strings, every weaves a line 4 to 12 plies the way to make the fishing line. This kind of fishing line is known very well as Anti-bite fishing line, not only but Kevlar can actually against nip, it with does not plant the braided line to be able to provide outstanding equally acts -between the quality, can achieve extremely high strength value.

However this gadget actually has the shortcoming. Its intensity is not very durable. Frequently under the stress situation will present the weary response, and it endures ability to the ultraviolet ray to be not so good. Hence, it needs to be protected and taken care of. And after line absorbing water, will become heavier.

The Secret of Fishing Line -- Introduction

Here we are going to talk about the significant element between fisherman and fish -- Fishing Line. Basically, modern fishing line can be classified into two categories, Monofilament line and Multifilament line. The former has included each kind of Nylon line and Fluorocarbon line, the state is the explicit independent fine lace; the latter refers to each on of fusion line, such as various Anti-bite line, Braided line, Fire line, and Spider line. Those are made of many thin strings by braiding, binding with heat, or coating with other material. Here are most common types of fishing line on the market.

• Nylon Line

At present we see the nylon line, most of the various co-polymer line, for the fishing people most often use it. The characteristic is high for the ductility and transparent. There would be a full cushion when you catch fishes and reduce oversized raises the bamboo pole strength and fish's momentum. But the resistance to wear is not good, very easy to let have tooth's fish to rub the nylon breaks, and its intensity will be destroyed by the ultraviolet ray. The merit is that is completely non - absorbent material. If you need the high transparency line on brook fishing, you may consider Nylon line.

• Fluorocarbon Line

It is made up Resin by content chemical element Fluorine and Carbon. The line material is tougher and harder, the transparency equally with the nylon. The anti-chemical agent and oxidation resistance ability is greatly strengthened; however, the ductility is low. Because of the characteristic, wear-resisting, most before wire uses this kind of line. In particular when the main line is for Fire line, due to the Fire line not wear-resisting easy to break, it matches this kind of line to use for the leader.

• Braided Line

The braided line in modern fishing community holds the pivotal status. This type of fishing line consists of many extremely thin fibres mixed. The basic construction is mostly the same, except for minor differences the characteristic which flaunted is also similar, like extremely low strain, superelevated strength, very soft and so on. Therefore, it becomes the ideal line for the very long main line to fish (e.g. deep-sea vessel fishing).

The primary cause of the difference of each kind of braided line performance lies in its institute to use the textile fiber material quality and the line body structure first. At present the most important braided line material has two kinds: Dyneema and Kevlar.

We are going to introduce Dyneema and Kevlar on next article.
