Copper and Copper Oxide Nanoparticles for Textile Finishing

Co-authors WIENER Jakub, MAHLTIG Boris

Copper and Copper Oxide Nanoparticles have recently drawn attention for their applications in Technical Textiles epically in healthcare industry. The present studies have been carried to find out the properties of Copper and Copper Oxide Nanoparticles for special applications Copper Oxide Nanoparticles are prepared by Wet Chemical Processes. In this technique CuSO4.5H2O is added with acetic acid and heated to 100 °C with continuous stirring. NaOH is added to the solution till pH = 7 is reached. The color of the solution changed from blue to black with precipitation. The black precipitation was washed 3-4 times, dried and make three different concentrations C1,C2 and C3 by diluting the solution. The woven and knitted cotton fabrics were dipped in a bath containing solution of nanoparticles at room temperature for 30 minutes. Then the fabrics were removed from the bath, padded, and dried at different drying Temperatures. Scanning Electron Microscopic (SEM) were conducted to study the phase and morphology of Nanoparticles. Abrasion Testing were carried out to find out the concentrations and other parameters affecting the abrasion characteristics of the fabrics. Anti-Microbial Testing of treated fabrics were performed. The results show that the fabrics can attain Anti-Microbial activity depending on the concentrations of nanoparticles on the fabrics. High concentration of nanoparticles is required for high antibacterial efficiency. ACKNOWLEDGEMENTS: For helpful discussion during material preparation we would like to thank Mister Dipl.-Chem. Thomas Grethe. Also many thanks are owed to Prof. Dr. Hajo Haase from RWTH Aachen for testing antimicrobial activities.
