摘要
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50 nm左右,且均匀性好,分散性好;抑菌实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268.58 mg/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。
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 good.The experiments show that the finished fabric has good antibacterial activity.When the silver content on silk fabric is about 268.58 mg/kg,the bacterial ratio is over 99%,and the bacterial ratio is over 98% after washing 50 times,indicating the good antibacterial property and wash durability of the fabric.
