摘　　要：利用铜氨溶液对粘胶纤维进行处理,制备了铜氨络合粘胶纤维。分析了铜氨溶液浓度、反应时间对Cu^(2+)结合量的影响。通过SEM、XRD和XPS表征了粘胶纤维的形貌与化学结构,测试了不同Cu^(2+)结合量下铜氨络合粘胶纤维的抑菌性及耐水洗性能。结果表明:随着铜氨溶液浓度的提高,Cu^(2+)结合量迅速增加;当溶液浓度达到25.00 mmol/L时,Cu^(2+)结合量达到最大值;反应30 min,即可达到络合平衡。铜氨溶液处理后,Cu^(2+)与粘胶纤维的羟基发生配位络合反应,纤维纵向分布着络合物小颗粒,形貌变粗糙,横向截面变化较小;纤维化学结构无明显改变。铜氨络合粘胶纤维显示出较好的抗菌性能,当铜氨溶液浓度达到0.30 mmol/L时,对大肠埃希菌和金黄葡萄球菌的抑菌率分别为97.80%和99.33%,经50次标准水洗后,抑菌率分别为83.40%和86.51%。Copper ammonia complex viscose fiber is prepared by treating viscose fibers with cuprammonium so⁃lution.The effects of cuprammonium solution concentration and reaction time on the binding amount of Cu^(2+)are analyzed.The morphology and chemical structure of copper ammonia complex viscose fiber are character⁃ized by SEM,XRD and XPS,and the antibacterial properties and washability of copper ammonia complex vis⁃cose fibers with different binding amounts of Cu^(2+)are tested.The results show that with the increase of the concentration of cuprammonium solution,the binding amount of Cu^(2+)increases rapidly,and when the concen⁃tration is 25 mmol/L,the binding capacity of Cu^(2+)reaches maximum,and the complexation equilibrium can be reached after 30 min of reaction.The fibers are longitudinally distributed with small complex particles,the mi⁃cro morphology becomes rough,and the cross-section changes less after the coordination complexation reac⁃tion between Cu^(2+)and hydroxyl groups in viscose fibers.There is no significant change in the chemical struc⁃ture of the fibers.Copper ammonia complex viscose fiber shows good antibacterial properties.When the con⁃centration of copper ammonia solution is 0.30 mmol/L,the antibacterial rates against Escherichia coli and Staphylococcus aureus are 97.80%and 99.33%,respectively.After 50 standard washes,the antibacterial rates are 83.40%and 86.51%,respectively.
