Fibrillation is the process of forming multiple short cuts or splits in the yarn parallel to the yarn axis. This is accomplished by passing the drawn tape over a roller that has some rows of sharpened pins.
With fibrillation process the surface speed of the fibrillation roll is greater than the yarn speed, causing the pin to first penetrate the tape, then “slice” the tape for a given length (determined by the difference in surface speeds). The result is a “fishnet” type pattern in the fibrillated tape. Fibrillated tapes can be twisted. We can offer fibrillation rollers with grooves for needle bars and needles bars as well. The pin projection, the numbers of the pins each cm, the pin pattern and density can be customized to the application.
