Abstract


Pineapple leaf fiber is a natural fiber materials that has potential as the tool of fishing gear. However, natural fibers has the weakness, such as the low of breaking strength and prone to decayed. Therefore, it is necessary to used biosizing process for solving this problem. One of the biosizing agent that can be used is chitosan. The aims of this research is to know the effect of acetic acid concentration and soaking time on biosizing process against the breaking strength, elongation, water absorption, and density of the yarn fiber pineapple leaves. The variable process in this research is the concentration of acetic acid 2%, 4% and 6%, and biosizing time 20, 40, and 60 minutes. The study was conducted over several stages, like synthesis of chitosan from the crab shell, spinning the fiber into yarn, and the biosizing process. Biosizing yarn has mechanical and physical properties greater than natural fibers. The best results in this study is the treatment with 2% acetic acid concentration with soaking time of the yarn for 60 minutes with a breaking strength is 7.21 kgf/mm2, 28% elongation, 220% water absorption, and the density is 0.463 gr/cm3 . Based on FAO, pineapple leaf fiber yarn meet the standard as a fishing gear material, because it has a greater breaking strength than polyamide and polyetylene.
Keywords: biosizing, breaking strength, chitosan, elongation, pineapple leaf fiber.
