摘　　要：为解决TiO_(2)在棉织物表面易团聚而导致光能利用率低的问题,采用蒙脱土与TiO_(2)二者协同对棉织物进行整理,以轧—烘—焙的方式将TiO_(2)和蒙脱土整理到棉织物上,制备了具有紫外线防护、抗老化和自清洁能力的棉织物。借助扫描电子显微镜、傅里叶变换红外光谱仪和紫外可见漫反射光谱仪对整理前后的棉织物进行分析,并通过纺织品紫外线测试仪、白度测试仪及织物风格仪等测试其紫外线防护性能、白度和风格变化。结果表明:整理后棉织物的长波黑斑效应紫外线(UVA)透过率为1.81%,中波红斑效应紫外线(UVB)透过率为0.87%,紫外线防护因子(UPF)为100+,且经50次皂洗后UPF值仍能维持在50+;整理后棉织物的抗老化性能提高了16.7%,具有较好的自清洁性能,其白度、透气性能、断裂强力和风格等有一定程度的损失,但损失不大。Objective In order to enable multifunctions of cotton fabrics and reduce agglomeration of TiO_(2) on cotton fabric surface,TiO_(2)/montmorillonite finishing agent was prepared by sol-gel method at lower temperature using tetrabutyl titanate and montmorillonite as the precursor,aiming to reduce agglomeration of TiO_(2).At the same time,the reduction of TiO_(2) consumption was fargetted to increase the added value of montmorillonite products.Method TiO_(2)/montmorillonite was firstly synthesized using ultrasound-sol-gel method and then deposited onto the surface of cotton fabrics by two-dipping and two-rolling processes.The properties of the cotton fabric before and after treatment were analyzed using Fourier transform infrared(FT-IR)spectrometer and energy dispersive spectrometer,while the surface morphologies of the cotton fabrics were analyzed by scanning electron microscopy.The whiteness,air permeability,breaking strength and elongation of TiO_(2)/montmorillonite-finished cotton fabrics were measured,respectively.In addition,the performance such as hand feel attributes,softness,smoothness and stiffness were measured.Rhodamine B was used as a test contaminant to qualitatively assess the self-cleaning performance of the TiO_(2)/montmorillonite finished cotton fabric.Results The SEM and EDS results indicated that TiO_(2)/montmorillonite was uniformly distributed on cotton fibers surface.UV-visible diffuse reflectance spectrum result showed that TiO_(2)/montmorillonite finished cotton fabric demonstrated excellent absorption capability to UV light,while the FT-IR result showed that the bonding mode between TiO_(2)/montmorillonite and cotton fiber was formed through covalent bonding.The anti-aging performance test showed that after 96 h UV irradiation,the strength loss of TiO_(2) finished cotton fabric was 22.9%,while the strength loss of TiO_(2)/montmorillonite finished cotton fabric was 15.4%,indicating that the montmorillonite compound could improve the anti-aging performance of TiO_(2).The self-cleaning performa
