一步法原位生成纳米Ag-ZnO复合整理棉织物

为了实现对纺织品的多功能化整理，本文以棉织物为研究对象，利用端氨基超支化聚合物HBP-NH2通过微波法在织物中一步原位控制生成了纳米Ag-ZnO，研究了整理后棉织物的抗菌和抗紫外性能等。结果表明：HBP-NH2具有多重作用，能够同时与Ag+和Zn2+反应控制生成纳米Ag和纳米ZnO。利用不同浓度整理液整理棉织物，可以获得不同纳米Ag和纳米ZnO含量的棉织物。XRD、XPS和SEM分析表明纳米纳米Ag和纳米ZnO成功整理到棉织物中，粒径为30～120nm。纳米Ag-ZnO复合整理棉织物同时赋予了其优异的抗菌和抗紫外性能，整理后的棉织物对金黄色葡萄球菌和大肠杆菌的抑菌率均达到了99.99%。另外，复合整理还能改善纳米Ag整理对棉织物白度的影响。

One-step in situpreparation of nano Ag-ZnO on cotton fabric formultifunctional finishing

In order to provide the textile with multifunctional properties, this research presents a method to in situ fabricate silver nanoparticles and ZnO nanoparticles on cotton fabrics by an amino terminated hyperbranched polymer (HBP-NH2) via a one-step microwave treatment. The antibacterial activity and UV protective property of treated cotton fabrics were measured. The results indicated that HBP-NH2 exhibited multiple functions. It not only can reduce silver ions to synthesize silver nanoparticles, but also react with zinc ions to generate ZnO nanoparticles. Cotton fabrics with different silver and ZnO contents were fabricated by treated with different concentration of reagents. XRD, XPS and SEM measurements verified that silver nanoparticles and ZnO nanoparticles produced in the cotton fabric successfully with diameter from 30 to 120 nm. The nano Ag-ZnO treated cotton fabrics shown excellent antibacterial activities and UV protective properties. The bacterial reduction rates of Staphylococcus aureus and Escherichia coli were all reached 99.99 %. Otherwise, the nano Ag-ZnO multifunctional finishing can also improve the whiteness of cotton fabric after treated with Ag.
