Tek kullanımlık hidrofilik ve antibakteriyel polipropilen nonwoven çarşafın geliştirilmesi

Especially at hospitals, nosocomial infections or the infections of patients are a great concern for the patients, visitors, and healthcare workers. Mortality caused by nosocomial infections is quite high in all over the world. It is reported that 40 % of all nosocomial infections can be prevented. In this study first of all, nosocomial infections and their effect on the human health are disscussed. And then the hospital sheets and their role on the spread of these infections were exam ined. The main purpose of this study is to develop a new dispo sable and antibacterial sheet. It was targetted to partially prevent spread of the infections in the hospitals. Because of the cost concerns, the disposablesheet was designed as polypropylene and spun-bond nonwoven. In the experimental section, 3 different polypropylene spun-bond nonwoven fabrics were supplied by General Nonwoven Ltd. Nonwovens were processed into a hydrophilic structure by using atmospheric O2 plasmatreatment. Silver based and PHMB based two different antibacterial finishing chemicals were applied to the samples by pad-batch method. Antimicrobial tests and physical tests were applied to the samples according to re levant ISO and ASTM standards for measuring their performance characteristics. Finally experimental results were evaluated using statistical methods and how, and at which level chemical finishing and atmospheric plasma process affects spunbond nonwoven fabric properties were tried to define.
