This research aimed to prepare nonwovens from polylactic acid and polybutylene succinate using the melt-blown process while varying the melt-blown process parameters, including air pressure (0.2 and 0.4 MPa) and die-to-collector distance (15, 30, and 45 cm). 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. Polylactic 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.
本研究旨在通过熔喷工艺，使用聚乳酸和聚丁二酸丁二醇酯制备非织造布，同时改变熔喷工艺参数，包括气压（0.2和0.4兆帕）和模头到收集器的距离（15、30和45厘米）。提高气压和模头到收集器的距离会导致生产出更细的纤维。同时，拉伸强度取决于所使用的聚合物、气压和模头到收集器的距离，并且断裂伸长率倾向于随着模头到收集器距离的增加而增加。关于热性能，当模头到收集器的距离增加时，聚丁二酸丁二醇酯非织造布的结晶度水平有所提高，这与X射线衍射分析得出的结晶度程度一致。在所有六种研究条件下，聚乳酸都能成功加工成非织造布，而在模头到收集器距离为15厘米时，聚丁二酸丁二醇酯非织造布无法形成。然而，两种聚合物都证明了使用熔喷技术加工成非织造布的可行性，显示出在纺织工业中的应用潜力。
