Abstract
Pulp properties of three varieties of abaca fibers from three stages of growth of the stalk were determined using the soda pulping process. Folding endurance, bursting strength, tearing strength and tensile strength varied highly among varieties, stages of growth of the stalks and levels of freeness of the pulp. Fibers from the young stalks were found superior in folds, bursting strength and tensile strength, but inferior in tearing strength. The tearing strength tended to increase with maturity. Pulp of fibers from all varieties at the three stages of growth exceeded the commercial long-fibered sulfate pulp from spruce and fair in tearing strength, tensile strength, and folding endurance, but, were only comparable to the letter in bursting strength. the density of handsheets tended to decrease with maturity. Variations in the dimension of the individual fibers were noted both among varieties and stages of growth.
