仙人掌纳米银的制备及其对桑蚕丝织物的抗菌整理

 利用纯天然仙人掌液还原制备了纳米银溶液，其制备方法简单，无污染。采用激光粒度仪（HPPS）和透射电镜（TEM）研究了仙人掌纳米银的尺寸和分布。利用制备的仙人掌纳米银溶液对桑蚕丝织物进行了整理，研究了织物的抗菌性能和耐洗性能。结果表明：生成的仙人掌纳米银粒径为50nm左右，且均匀性好，分散性好，抑菌试验表明整理后的桑蚕丝织物有很好抑菌效果，当织物上银含量为268.58mg/kg时，抑菌率达到了99%以上，经洗涤50次后，抑菌率依然保持在98%以上，说明织物具有优异的抗菌耐洗性能。

Preparation of cactus nanoparticles and their application in antibacterial treatment of B.mori silk

Nano-silver solution was prepared by deoxygenation with natural cactus solution,which is simple and non-polluting.The size and distribution of cactus silver nanoparticles were studied using HPPS and TEM.Functional treatment of the B.mori silk fabric was performed with nano-silver solution,and the antibacterial property and wash durability of the treated fabric were investigated.The results showed that the resultant cactus silver nanoparticles have a size about 50 nm,the uniformity and the dispersivity is go...
