摘要:
The present invention provides a method of manufacturing a polyurethane foam surface-coated with chitosan, the method comprising the steps of: (1) manufacturing a polyurethane foam of a continuous sheet containing calcium ions; and (2) forming a chitosan coating layer on a surface of the polyurethane foam in a roll-to-roll manner capable of controlling the thickness of a chitosan coating liquid. The polyurethane foam of the present invention is excellent in absorption speed and absorption power.COPYRIGHT KIPO 2020본 발명은 (1) 칼슘이온이 포함된 연속식 시트의 폴리우레탄 폼 제조단계; 및 (2) 상기 폴리우레탄 폼 일면에 키토산 코팅액을 두께조절이 가능한 롤투롤(roll to roll) 방식으로 키토산 코팅층이 형성되는 단계를 포함하는 키토산으로 표면 코팅된 폴리우레탄 폼 제조방법을 제공한다.
