本発明は高分子材料技術の分野に属し、具体的には変性ポリ乳酸、その製造方法、およびスパンボンド不織布の製造におけるその用途に関する。本発明の変性ポリ乳酸の製造方法は以下の工程を含む：ポリ乳酸をN,N,N',N'-テトラグリシジル-4,4'-diaminodiphenylmethane, and then granulating the mixture using a twin-screw extruder. The resulting modified polylactic acid exhibits improved thermal stability, successfully solving the problem of polylactic acid being unable to be processed into nonwoven fabrics on large-scale spunbonding equipment. The modified polylactic acid does not affect the production of spunbonded nonwoven fabrics, and its processing is smoother.
