Beschreibung
Zusammenfassung:	The present invention relates to a nanofiber sheet for soft tissue regeneration and reinforcement and a manufacturing method thereof. More specifically, the nanofiber sheet for soft tissue regeneration and reinforcement is poly(glycolic-co-latic acid)(PGLA) and biodegradable polymers including polyvinylpyrrolidone (PVP), and the molar ratio of glycolic acid block : lactic acid block of the poly(glycolic-co-latic acid) (PGLA) is 30 : 70 to 40 : 60. The present invention can regenerate and strengthen soft tissue by maintaining the properties even for more than three weeks in vivo, and is absorbed into the body within 15 weeks and is harmless to the human body. 본 발명은 연조직 재생 및 강화용 나노섬유 시트 및 이의 제조방법에 관한 것으로서, 보다 구체적으로 상기 연조직 재생 및 강화용 나노섬유 시트는 폴리(글리콜릭-코-라틱산)(Poly(glycolic-co-latic acid), PGLA) 및 폴리비닐피롤리돈(Polyvinylpyrrolidone, PVP)을 포함하는 생분해성 고분자를 포함하고, 상기 폴리(글리콜릭-코-라틱산)(Poly(glycolic-co-latic acid), PGLA)의 글리콜릭산 블록: 라틱산 블록의 몰비가 30 : 70 내지 40 : 60인 것에 특징이 있다.
