The application of antimicrobial finishes to textiles can prevent bacterial growth and might reduce the risk of infection resulting from textiles that are contaminated with pathogenic microorganisms in hospitals. The main aim of this study was the determination of the antibacterial activities of chemical treatments applied to textiles. Comparison of testing methods assessing antibacterial efficiency was conducted. These studies were performed in order to select the right methods of evaluating the bactericidal and bacteriostatic activity of antibacterial modified textiles. Antibacterial modified polyester fibres and fabrics made from cotton (100%) applied with quaternary ammonium salts were tested. Textiles treated with bacterial agent were compared with reference samples (not treatment with the disinfectant). The Standards ISO/DIS 20645/2002 andAATCC 147/ 1998 suitable for assessment of bacteriostatic activity were applied. For assessment of bactericidal activity ATCC Test Method 100-1998 were applied. The bacterial strains recommended by the above standards such as: Klebsiellapneumoniae (ATCC 4352),Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 11229) was tested. Additionally Pseudomonas aeruginosa (ATCC 9027) was examined. Tested fibres did not show antibacterial activity. Samples of antibacterial textiles were washed through laboratory laundering cycles. Residual antimicrobial activity was measured after washes. The fabric showed antibacterial activity against K. pneumonia and S. aureus. The examined specimens showed no bacteriostatic activity against E. coli and P. aeruginosa. The results obtained in two applied quality methods were comparable in assessing antibacterial activity of finishes. Reduction of bacteria in quantitative method was 90%. In quality method ISO/DIS 20645/2002 effectiveness of the treatment against K. pneumonia was retained up to five laundering cycles and against S. aureus--twenty laundering cycles.
将抗菌整理剂应用于纺织品可以防止细菌生长，并可能降低因医院中被致病微生物污染的纺织品而导致感染的风险。本研究的主要目的是测定应用于纺织品的化学处理的抗菌活性。对评估抗菌效率的测试方法进行了比较。进行这些研究是为了选择评估抗菌改性纺织品的杀菌和抑菌活性的正确方法。测试了抗菌改性聚酯纤维以及由100%棉制成并施加了季铵盐的织物。将用细菌制剂处理过的纺织品与参考样品（未用消毒剂处理）进行比较。采用了适用于评估抑菌活性的ISO/DIS 20645/2002标准和AATCC 147/1998标准。对于杀菌活性评估，采用了ATCC测试方法100 - 1998。测试了上述标准推荐的细菌菌株，如：肺炎克雷伯菌（ATCC 4352）、金黄色葡萄球菌（ATCC 6538）、大肠杆菌（ATCC 11229），此外还检测了铜绿假单胞菌（ATCC 9027）。测试的纤维未显示出抗菌活性。抗菌纺织品样品经过实验室洗涤循环。洗涤后测量残留抗菌活性。该织物对肺炎克雷伯菌和金黄色葡萄球菌显示出抗菌活性。所检测的样品对大肠杆菌和铜绿假单胞菌没有抑菌活性。在评估整理剂的抗菌活性时，两种应用的质量方法所获得的结果具有可比性。定量方法中细菌减少了90%。在质量方法ISO/DIS 20645/2002中，对肺炎克雷伯菌的处理效果在多达五个洗涤循环中得以保持，对金黄色葡萄球菌的处理效果在多达二十个洗涤循环中得以保持。
