Agricultural Process and Technology
The process of preparing abaca fiber involves four (4) major phases: Harvesting of Stalks, Extraction of Fiber, Drying, and Grading and Baling.
The abaca propagates itself through suckering, or the growing of shoots from the roots. When all the leaves have been formed from the stem, flower buds develop, at which time the plant has reached maturity and is then ready for harvest.
In a fully developed plantation where there are suckers that mature in rapid succession, harvesting is done as often as possible. The initial harvest of the abaca plant is done within 18 to 24 months from planting.
There are four (4) stages in the harvesting process: Cleaning, Topping, Tumbling, and Tuxying.
The different groups of tuxies produce distinct grades of fiber. The outermost leafsheaths exhibit brown portions. The middle layers carry tinges of light green or streaks of purple. The inner layers are ivory to white in color.
Hand Stripping is a fully manual process of extracting fiber which uses a device made up of a movable knife, a knife rest or base, and a weight to keep the movable portion firmly in position as stripping is performed. In this method, the tuxies or leafsheath splits are inserted between a block and the stripping knife which can be either serrated or non-serrated. The foot pedal is then released to clamp the tuxy firmly into place. The stripper then pulls the tuxy away from the knife with full force, both hands clasping the tuxy wound around a wooden pulling aid.
Machine Stripping, on the other hand, is a semi-mechanized improvement on the Hand Stripping process. The tuxy is wound around a tapered-shaped spindle which is kept in motion by an electric motor.The speed at which the spindle draws the fiber over the knife depends on its position. By using this method, a stripper can process many leafsheaths in a short amount of time and, with the proper kind of knife, produce fibers of uniform grades.
