Pre-extraction treatment of Buri (Corypha utan Lamk.) petioles and its effects on buntal fibers

Abstract

Buri petioles were subjected to different pre-extraction treatments to determine an easier method of buntal fiber extraction, which can be an alternative to manual pulling. The treatments were control or no treatment, 2 hr soaking in 20:20:60 acetic acid-hydrogen peroxide-water solution heated in a hot water bath, 2 hr boiling in tap water, 2 hr steaming and 15 d water retting. The effect of the different pre-extraction treatments on color, tensile strength and percent elongation of the fibers were determined. Easiness of pulling out the fibers, economic preference of farmers and non-farmers and the quality of extracted buntal fibers from each pre-extraction treatment were also ranked. Fiber color was affected by pre-extraction treatments, where the change in color of the fibers was greatly seen in boiling in tap water and steaming of petioles. Tensile strength did not differ significantly, while percent elongation of all treated fibers were significantly smaller compared to untreated fibers. Values obtained in this study were comparable with what the Philippine Fiber Industry and Development Authority (PhilFIDA) reported for buntal fibers being used in the industry. Farmers and non-farmers both prefer hot water bath in acetic acid-hydrogen peroxide-water solution and water retting as pre-treatment since fibers are easiest to extract. But considering the easiness of extraction and buntal fiber quality, they prefer using water-retted petioles. Farmers still preferred to extract buntal fibers from untreated petioles while non-farmers chose the water-retted petioles as pre-treatment.
