Razvoj biorazgradljivih vlaknovin iz vlaken, pridobljenih iz navideznega stebla rastline Alpinia purpurata, in polimlečne kisline kot veziva

This study investigates the development of biodegradable nonwoven fabrics utilizing Alpinia purpurata pseudo-stem fibres, bonded with poly lactic acid (PLA) through a thermal bonding process. Given the underutilization of Alpinia purpurata fibres, this research explores their potential for sustainable textile applications. The fibres were extracted via decortication and blended with PLA at varying mass ratios (90/10, 80/20, 70/30), followed by comprehensive characterization. Evaluations included fabric mass per unit area, thickness, air permeability, tensile strength, elongation, wetting time, moisture regain and surface morphology. The results indicate that increasing PLA content enhances tensile strength but reduces air permeability and water absorption. Conversely, a higher proportion of Alpinia purpurata fibres improves breathability and moisture regain. These findings demonstrate that Alpinia purpurata fibres, in combination with PLA, can produce nonwoven fabrics with tunable properties, offering promising potential for environmentally friendly textile applications.
