Beschreibung
Zusammenfassung:	The invention discloses a slow-release multifunctional polylactic acid textile containing chlorogenic acid and a preparation method of the slow-release multifunctional polylactic acid textile, and belongs to the field of preparation of functional fibers and non-woven materials. The preparation method comprises the following steps: carrying out melt blending granulation on CGA and a hydrophilic polymer ethylene-vinyl alcohol copolymer (EVOH) to prepare EVOH/CGA blended slices; then carrying out melt blending granulation on the PLA and the EVOH/CGA blended slices to prepare PLA/EVOH/CGA blended slices; and finally, carrying out melt spinning or spunbond non-woven processing by taking the PLA/EVOH/CGA blended slice as a raw material to prepare the slow-release multifunctional PLA fiber or non-woven material. The hydrophilic polymer EVOH is introduced, the release rate of the functional factor CGA is increased, and the release rate of the CGA in the PLA fiber or the non-woven material can be regulated and control
