Applications and structural determinations of silver and walnut shell extract on textile products by sol gel method

In this study juglone, was obtained by extraction method using the soxhlet apparatus from the walnut shell and its Cu (II), Mn (II), Zn (II) complexes were synthesized. The structures of the obtained complexes were characterized by spectroscopic methods such as, elemental analysis (C, H, N, S), FT-IR, UV-Vis. Juglone and its complexes were applied on 100% cotton fabric. Fabrics treated with juglone, and metal complexes were coated with nanosilver obtained by sol gel method. Surface structures of fabrics coated with juglone, metal complexes and nano silver were investigated with SEM/EDX analysis, ICP-OES. Antimicrobial activity tests of fabrics coated with juglone, metal complexes and all the compounds coated with juglone complexes and nano silver were gram positive; Staphylococcus aureus Rosenbach ATCC-6538, Bacillus cereus ATCC 7064, gram negative and it was also performed against Escherichia coli ATCC-8739, Salmonella typhimurium strains and Candida albicans ATCC-90028 fungal species. The result obtained showed that, the fabrics coated copper complex with NPsAg has the best activity.
