医用SMMS和木浆非织造布的拒水拒油整理

采用乳液聚合制备了含氟整理剂,通过轧烘焙工艺对丙纶复合非织造布SMMS和木浆非织造布进行了整理,研究了整理剂用量、焙烘时间和焙烘温度对整理效果的影响.结果表明:当整理剂用量为20 g/L,120℃焙烘90 s时,SMMS非织造布拒水等级为10级,拒油等级为8级.当整理剂用量为20 g/L,110℃焙烘100 s时,木浆非织造布拒水等级为10级,拒油等级为8级.非织造布具有良好的抗酒精性能、抗血液渗透、透气性、断裂强力及耐静水压性能,能满足医用要求.

Water and oil-repellent treatment on medical SMMS and wood-pulp nonwoven fabric

The fluorine-containing finishing agent was prepared through emulsion polymerization.The polypropylene complexed nonwoven fabric SMMS and wood-pulp nonwoven fabric was treated with fluo rine-containing finishing agent via pad-dry-cure technology,and the influence of the finishing agent dosage,curing temperature and time on the finishing result was investigated.The result showed that when finishing agent dosage was 20 g/L,cured at 120 ℃ for 90 s,the water-repellent rating of the treated SMMS nonwo ven fabric was 10 and the oil-repellent rating was 8;when finishing agent dosage was 20 g/L,cured at 110 ℃ for 100 s,the water-repellent rating of the treated wood-pulp nonwoven fabric was 10 and the oil-re pellent rating was 8.The nonwoven fabric had good resistance to alcohol,blood penetration,breathable proper ty,breaking strength and static water pressure,which could meet the medical requirements.
