Viscose fabrics were modified with alginate and doped with copper ions, to investigate the effect of copper doping on their antibacterial and UV blocking properties. The modified fabrics were characterized using FTIR, UV spectroscopy, SEM and chromatometric analysis and their copper uptake properties were investigated. The antibacterial effect of the treatments was evaluated before and after repeated washings (up to 50 cycles). The resulting composite materials showed excellent antibacterial properties with up to 100 % reduction of bacteria, even from very low copper content, while alginate/copper treatment increased the UV radiation protection index by 261 %, offering a composite fabric with improved performance.

用海藻酸盐修饰粘胶纤维织物并掺入铜离子，以研究铜掺杂对其抗菌和紫外线阻隔性能的影响。用FTIR，UV光谱，SEM和色谱分析法对改性织物进行了表征，并研究了其对铜的吸收性能。在重复洗涤之前和之后（最多50个循环）评估处理的抗菌效果。所得的复合材料即使在极低的铜含量下，也显示出优异的抗菌性能，最多可减少100％的细菌，而藻酸盐/铜处理使紫外线辐射防护指数提高了261％，从而为复合织物提供了改进的性能。
