Test and analysis of reusable surgical gowns washing resistance
摘要
Abstract
In order to investigate the washing resistance of reusable surgical gowns and evaluate the service life of the surgical gown,a 3-layer surgical gowns was developed,which was composed of polyester fiber(PET)knitted fabric as the surface layer,polytetrafluoroethylene(PTFE)film as the middle layer,99%polyester fiber+1%conductive filament knitted fabric as the inner layer.After washing 10 times,20 times,30 times,50 times,60 times,the resistance to liquid penetration,contact angle,resistance to wet microbial penetration,bursting strength and surface morphology of the reusable surgical gowns were tested and analyzed before and after washing.The results showed that after repeated washing for 60 times,the resistance to liquid penetration was still above 100 cm H2O,the bursting strength of dry and wet state was above 270 kPa,and high mechanical property was maintained.After repeated washing,the surface structure of the surgical gowns was loose,the fibers were broken,the surface changed from hydrophobic to hydrophilic,it was easily permeated by liquid,the barrier index was not changed,and it still had the function of blocking bacteria in the wet state.It is considered that the hydrophobic property of reusable surgical gowns have changed significantly,and the manufacturers should pay attention to the surface treatment technology and improving the material's anti-washability.The number of decontamination should be determined according to the actual verification results to ensure the safety and effectiveness of the product in the whole life cycle.关键词
