Carbon fabrics
Each fabric has its own characteristics, but you can tell them apart at a glance.
- Taffeta
Carbon taffeta fabrics form a checkerboard pattern with the fibres
90° weave. Low deformation. Very good dimensional
dimensional stability. Little fringing during cutting.
Difficult to drape. Because of this draping difficulty
taffeta fabrics are generally used on flat surfaces.
- Twill
Carbon twill fabrics are more commonly used because
their drapability is better than taffeta fabrics.
Medium deformation. This fabric is also widely used for its
aesthetic qualities. There are 3/1 twills, 2/2 twills, etc.
This means that the fibers intersect every 3 or 2 fibers.
There are different spindle widths. Their names are: 3K -10K - 20K.
One K is equivalent to 1000 threads and corresponds to 1mm width.
3K is equivalent to 3000 threads per spindle.
On a palm, whatever the fabric used (twill or taffeta) and whatever the number of Ks, there are exactly the same number of threads horizontally as on vertical.
In theory, both mechanically and by construction, the fabric and the Ks have no influence. In practice, however, we have found that the higher the number of Ks, the stiffer the fin, and the lower the K (3K), the more responsive the fin. In terms of stiffness, there's no difference between a Sergés and a Taffetas, although the Sergé fin spins less than the Taffetas fin. The theory doesn't explain it, but there it is!
The most difficult thing is to find a way of using them at the same time, so as to combine their two qualities without the deformation caused by the different structure. This is what Denty Spearfishing has managed to achieve.
We therefore chose a 3K Sergés fabric for the water-loading phase and a Taffta fabric for the unloading phase, to make the best use of the reactivity of the two materials in their respective working axes.
Déclives
The latest-generation Denty Spearfishing Black Mamba V2 fins go one step further and feature 8 Hexagon and V-shaped declivities. In other words, in addition to the two outer composite sheets, there are 7 different-length fabrics inside in pure carbon.
The aim is to obtain a fin that is both powerful in front of the foot to "load" the water (Sergé) and sufficiently supple and responsive at the tip to "leak water" (Taffeta). It finishes the job on its own, restoring some of the power transmitted to the load thanks to Taffeta's 90° weave.
This nervousness and responsiveness are essential for the movement to be as fluid as possible, to reduce dead time when reaching the top or bottom of the stroke.
Contrary to popular belief durant over the years, the "elasticity" of the liner (however small it may be) does not lead to a loss of power, but rather to a restitution of power at the end of the movement.
The three standard hardnesses Soft (green), Medium (yellow) and Medium Power Plus (red) are obtained by shifting the declivities forwards or backwards.
The Denty liner
The choice of Denty liner is based on the following points: Weight 400 gr Sail 320 gr
- Solidity: very long life
- Reliability of size chart: Conforms to European size chart - Impact of weight: Neutral in water
- Material: Synthetic rubber with mineral filler and microbubbles.
