ABSTRACT
OBJECTIVE To observe the property,the bacterial retaining effect and the storage time of nonwoven and wrinkle paper.METHODS The weight and shape,and the retaining effect and storage time of 14 kinds of nonwoven and wrinkle paper were observed.RESULTS Bacteria could go through all kinds of nonwoven and wrinkle paper.After sterilization,different quality and different package layer of nonwoven could be kept for 7-30 days.One or two layers of wrinkle paper package could be kept for 3 months.There was no significant difference in keeping place-in sterile room or in ward.CONCLUSIONS The time of preservation validity is related to the quality and the layers of nonwoven.It is suggested that two layers of lower quality nonwoven(28-30 g/m2) be used for lower and middle level dangerous medical material,with 7-10 days of preservation;four layers of high quality nonwoven(above 33 g/m2) could be used for high level dangerous medical material,with a 1 month of preservation.
