Study on Plasma Modification Process on PBT Melt - blown Nonwovens and their Performances

研究用低温等离子体引发丙烯酸接枝PBT熔喷非织造布的主要因素.探讨了低温等离子体处理时间、处理功率、接枝温度、单体质量分数对接技改性的影响规律,并对接枝产品表面性能进行了分析.结果表明:通过低温等离子体引发丙烯酸接枝可改善熔喷非织造布的润湿性以达到血液用过滤材料的要求.

Main factors affecting the low temperature plasma initiation and graft modification of acrylic acid onto PBT melt - blown nonwovens are studied. The relations between product wettability and plasma power, initiating time, grafting temperature and monomer concentration are investigated. The surface performance of grafted products are analyzed. It is believed that wettability of PBT nonwovens is greatly improved by plasma initiation and graft modification so as to meet the needs of blood filtration materials.
