Effect of Chitosan, Aluminum Oxide and Silver Nanoparticles on Antibacterial, Deodorizing and Moisture Absorption Properties of Nonwoven Polyester Fabrics for Use in Medical Textiles

ABSTRACT          Background and Objective: Hospital clothing and textiles have a great role in providing medical services to patients. Hospital services would not be possible without using these textiles. The aim of this study was to prepare non-woven polyester for use in medical textiles.          Methods: In this study, most important expected properties of hospital clothing were created on polyester fabrics via various stages of finishing using chemicals such as calcium chloride, sodium alginate, chitosan and nanoparticles of silver nitrate and aluminum oxide. Antibacterial (activity against Staphylococcus aureus), deodorizing and wicking properties of samples were evaluated using nano-biomaterials via standard tests.           Results: The water absorption rate of nonwoven samples that were finished with chitosan significantly improved. The results also showed favorable level of antimicrobial activity caused by silver nitrate and chitosan. In addition, deodorizing activity was observed in all samples. However, silver nitrate-finished samples had higher deodorizing activity. The capillary action of all samples reduced after completion of all finishing procedures.           Conclusion: The results show that the use of chitosan and alginate along with nanoparticles of silver nitrate and aluminum oxide can be effective in achieving the desired properties of medical textiles.         Keywords: Medical textiles, antibacterial substances, chitosan, silver nitrate.
