摘　　要：为解决天然活性成分改性聚酯纤维生产过程中,天然成分不耐高温易损失导致功能下降的问题,通过分子巢技术将超临界CO_(2)萃取获得的橙活性成分装载入介孔SiO_(2)载体中,进而制备具有良好抑菌、抗病毒效果的聚酯/二氧化硅/橙活性成分改性纤维。对改性纤维的形貌结构、化学结构、力学性能、活性成分含量、抗菌性能和抗病毒性能等进行测试与分析。结果表明:制备的介孔SiO_(2)的尺寸为(100±5)nm,比表面积为729.7 m^(2)/g,平均孔径为2.55 nm;聚酯/二氧化硅/橙活性成分改性纤维的断裂强度为3.22 cN/dtex,纤维中橙活性成分柚皮甙含量为(0.41±0.05)mg/kg,抑菌率大于或等于91%,抗病毒率大于或等于99%,均显著优于普通聚酯纤维(p<0.01)。In order to solve the problem of functional degradation caused by the loss of natural active ingredients in the production process of polyester fibers,the molecular-nesting technology was independently developed.The orange active ingredients obtained by supercritical CO_(2) extraction was loaded into mesoporous silica nanoparticles(MSNs)carrier to obtain the polyester/silica/orange active ingre-dient(PET/SiO_(2)/O)fiber with good antibacterial and antiviral effects.The morphology,chemical structure,mechanical properties,active ingredient content,antibacterial and antiviral properties of the modified fiber were characterized and analyzed.The results show that the size,specific surface area and average pore diameter of the achieved MSNs are(100±5)nm,729.7 m^(2)/g and 2.55 nm,respectively,and the fracture strength of PET/SiO_(2)/O fiber is 3.22 cN/dtex.The content of orange active ingredient naringin in PET/SiO_(2)/O fiber is(0.41±0.05)mg/kg,the antibacterial rate is above 91%,and the antiviral rate is above 99%,which are significantly better than that of the common polyester fibers(p<0.01).
