Abstract
This research aimed to prepare and characterize nonwovens from poly lactic acid and polybutylene succinate, which is a biodegradable polymer instead of using synthetic polymers. This research using the melt-blown process while varying the melt-blown process parameters to study the characteristics of non-woven fabrics, including air pressure (0.2 and 0.4 MPa) and die-to-collector distance (15, 30, and 45 cm). The result shown that increasing the air pressure and die-to-collector distance resulted in the production of smaller fibers. Simultaneously, the tensile strength was dependent on the polymer, air pressure, and die-to-collector distance used, and the percentage elongation at the break tended to increase with an increasing die-to-collector distance. Regarding thermal properties, the PBS nonwovens exhibited an increased level of crystallinity when the die-to-collector distance was raised, consistent with the degree of crystallinity obtained from X-ray diffraction analysis. Poly lactic acid could be successfully processed into nonwovens under all six investigated conditions, whereas nonwoven polybutylene succinate could not be formed at a die-to-collector distance of 15 cm. However, both polymers demonstrated the feasibility of being processed into nonwovens using the melt-blown technique, showing potential for applications in the textile industry.
