Abstract:

This paper briefly introduced the preparation technologies of poly(lactic acid) (PLA) nonwovens such as electrospinning, spunbonding, and meltblown techniques. The hydrophilic modification methods of PLA nonwovens such as fiber?forming modification, web?forming modification and post?finishing were especially introduced. Then, the applications of PLA nonwovens in the medical and health field, including drug release, wound dressing and mask manufacturing, was discussed. Finally, the future development trend in the hydrophilic modification of PLA nonwovens was prospected.

Key words: poly(lactic acid), biodegradability, biocompatibility, preparation process, hydrophilic modification, wettability, medical care and health
