Study on annealing process of polylactic acid melt blown microfibrous for medical packaging
摘要
Abstract
To enhance the mechanical performance of polylactic acid(PLA)-based melt-blown microfibrous materials for medical packaging,PLA/PCL@EBS melt-blown microfibrous samples were subjected to annealing.The structural mor-phology,crystallinity,and mechanical properties of the samples were systematically characterized.The results indicated that the annealing action reduced fiber diameter,with 72.0%of fibers falling within a 6 µm diameter range at elevated annealing temperatures.Increasing the annealing temperature from 60 to 80℃significantly improved crystallinity,rising from 5.1%to 29.7%.Concurrently,mechanical properties were enhanced:machine-direction and cross-direction frac-ture strengths increased from 16.4 and 3.4 N/5 cm to 30.9 and 8.4 N/5 cm,respectively,while top-break strength im-proved from 10.1 N/5 cm to 18.9 N/5 cm.Response surface methodology further revealed optimal mechanical perfor-mance at an annealing temperature of 70 ℃ and a duration of 30 minutes.关键词
