【Abstract】 PLA (polylactic acid) is suitable for melt-blown technology through experiment and analysis. Melt-blown PLA nonwovens which has good filtration property is produced by optimizing process parameters. At the same time the main process parameters (including air velocity, distance from die to collector-DCD and electret) which influence the filtration property of meltblown PLA nonwoven fabric are discussed.更多还原
