Paper fiber flat braided cotton wicks are generally considered to be self-trimming wicks with a predictable posture and good rigidity. This type of wicks are good performers in a broad number of different base material formulations and are offered by all the major wick braiders servicing the candle industry around the world.
The braiding pattern utilized in the construction of this type of wicks, in combination with the fiber components utilized (cotton and paper), result in a natural braiding pattern of intertwined light colored cotton and dark colored paper fibers. The unique pattern is different on each “side” of the flat braided wick and can be observed with the naked eye.
When “wet” (waxed), the paper fibers tend to darken in color, accentuating the visual difference of each side.
During the waxing process, it is normal for the flat wicks to align on the reel on their different “sides” and, may “rotate” several times on the same reel. As the flat wick rotates from side to side, the visual appearance of lighter and darker areas on the reel may be apparent. This is a normal occurrence which does not affect the performance of the wick.
