This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity against antibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions of different concentrations provided free carboxyl groups for binding of Cu²⁺ -ions from copper (II) sulfate solution which were further reduced with sodium borohydride in alkaline solution. An increase in the concentration of applied oxalic acid resulted in larger amounts of free carboxyl groups on the cotton fibers, Cu²⁺ -ions uptake and total amounts of Cu-based nanoparticles after reduction. XPS and XRD analyses suggested that nanoparticles mainly consisted of CuO with fractions of Cu₂O. Fabricated textile nanocomposites ensured maximum reduction of Gram-negative E. coli ATCC 25922, E. coli NCTC 13846, E. coli ATCC BAA-2469, K. pneumoniae ATCC-BAA 2146 and P. aeruginosa ATCC 27853, Gram-positive bacteria S. aureus ATCC 25923 and S. aureus ATCC 43300 and yeast C. albicans ATCC 24433. Additionally, controlled release of Cu²⁺ -ions from fabrics into the physiological saline solution was obtained within 24 hours.

这项研究讨论了制造具有抗菌活性的纺织品纳米复合材料的可能性，所述纳米复合材料抗抗生素抗性细菌菌株和酵母菌。用不同浓度的草酸溶液对棉织物进行改性可提供游离羧基，以结合硫酸铜（II）溶液中的Cu ^2+离子，然后在碱性溶液中用硼氢化钠进一步还原该羧基。施用草酸浓度的增加会导致棉纤维上的大量游离羧基，Cu ^2+离子的吸收以及还原后Cu^基纳米颗粒的总量。XPS和XRD分析表明，纳米颗粒主要由CuO和部分Cu _2组成O.纺织纳米复合材料可确保革兰氏阴性菌ATCC 25922，大肠杆菌NCTC 13846，大肠杆菌ATCC BAA-2469，肺炎克雷伯氏菌ATCC-BAA 2146和铜绿假单胞菌ATCC 27853，革兰氏阳性菌的最大减少金黄色葡萄球菌ATCC 25923和金黄色葡萄球菌ATCC 43300和酵母白色念珠菌ATCC24433。另外，在24小时内获得了Cu ^2+离子从织物到生理盐溶液中的受控释放。
