摘　　要：为解决在无黏结剂条件下纳米光催化材料在纺织品上复合牢度低的问题,采用低温复合处理技术,将TiO_2纳米颗粒均匀负载于苎麻织物上,并通过扫描电子显微镜、傅里叶红外光谱仪、透气性测试仪、万能拉伸仪和甲醛测试系统等测试方法对织物性能进行表征。结果表明:TiO_2纳米颗粒可通过低温复合处理技术均匀固定于苎麻织物上,织物在-10℃低温浴配合400 N/cm的压力下每次浸渍10 min,浸扎处理3道后除甲醛效果最佳;处理后织物表面羟基量增多,织物保持了原有透气性且断裂强力和断裂伸长未受到处理影响;处理后织物在120 min内实现了87.14%甲醛去除率。In order to solve the problem that nano photocatalytic materials have low bonding strength on textiles under adhesive-free condition,low temperature bonding treatment was adopted to uniformly load TiO_2 nanoparticles（TiO_2 NPs） on ramie fabrics.The properties of the treated ramie fabrics were evaluated by a scanning electron microscope,a Fourier transform infrared spectroscope,a porosimeter,a universal tensile test machine and a formaldehyde test system.The results show that TiO_2 NPs can be evenly fixed on the ramie fabrics.The sample treated in the bath at -10 ℃ for 3 cycles（10 min/cycle,400 N/cm） shows the highest formaldehyde elimination rate.After the treatment,hydroxyl groups on the fabric surface are increased while the air permeability,tensile stress and elongation of the fabrics are maintained.Within 120 min,about 87.14% formaldehyde can be eliminated by the treated fabrics.
