摘要： A system for preparing a polylactic acid (PLA) spunbond nonwoven fabric is provided. In particular, the system includes a first PLA source configured to provide a stream of molten or semi-molten PLA resin; a spin beam in fluid communication with the first PLA source, the spin beam configured to extrude and draw a plurality of PLA continuous filaments; a collection surface disposed below an outlet of the spin beam onto which the PLA continuous filaments are deposited to form the PLA spunbond nonwoven fabric; a first ionization source positioned and arranged to expose the PLA continuous filaments to ions; and a calender positioned downstream of the first ionization source.
