This research investigates the mechanical and physical qualities of kenaf fibers (variety HC-95) harvested at various intervals—specifically at 90, 100, 110, and 120 days after sowing (DAS)—at the Jute Research Regional Station in Kishoreganj. Two factors were considered: green and yellow fiber samples. The study assessed four key physico-mechanical attributes: bundle strength, whiteness, fineness, and texture. Results indicate that green fibers harvested at 110 DAS exhibited superior bundle strength, whiteness, fineness, and texture compared to fibers from other harvesting intervals. For yellow fibers, both 100 DAS and 110 DAS showed similar performance, although 100 DAS fibers demonstrated higher attributes, except for texture. Additionally, whiteness levels in both green and yellow fibers were highest at 90 DAS and 100 DAS. Overall, green kenaf fiber plants were found to be more favorable for spinning quality compared to yellow plants, highlighting the importance of harvest timing in optimizing fiber quality.
