以海藻酸钙纤维和纳米银溶液为原料，采用浸渍富集法制备了载银海藻酸钙纤维。采用红外光谱（FTIR）和扫描电镜（SEM）表征了载银海藻酸钙纤维的结构，测试了载银前后海藻酸钙纤维的吸湿性能和力学性能，检测了不同银含量载银海藻酸钙纤维的抗菌性能。结果表明，载银海藻酸钙纤维表面的银颗粒粒径在20～50 nm左右，载银对海藻酸钙纤维的吸湿性能和力学性能影响较小，当载银海藻酸纤维银含量达到18000 mg/kg时，对白色念珠菌（ATCC 10231）、大肠杆菌（ATCC 25922）的抑菌率均达到99%以上。

Silver-loaded calcium alginate fibers have been prepared using alginate fiber and nano-silver solution as raw materials via impregnation enrichment method. The structure of the silver-loaded calcium alginate fiber was characterized by FTIR and SEM. The moisture absorption and mechanical properties of the silver-loaded calcium alginate fiber were tested compared with the normal calcium alginate fiber. The antimicrobial properties of the silver-loaded calcium alginate fiber of different silver content were also detected. The results showed that the size of silver particles on the surface of the Ag-loaded calcium alginate fiber was about in the range of 20~50 nm. Loading silver has little impact on the moisture absorption and mechanical properties of the calcium alginate fiber. When the silver content of silver-loaded silver alginate fibers reaches 18 000 mg/kg, the antibacterial rate of C.albicans (ATCC 10231) and E.coli (ATCC 25922) is all more than 99%.
