摘　　要：为了研究纺织品蓝晒工艺的最佳实验条件,用K/S值对比棉、亚麻和蚕丝织物蓝晒效果,通过感光剂扩散及蓝晒实验分析颜色差异的原因,得到润湿性对载体蓝晒效果影响显著,调控载体表面感光剂扩散性对蓝晒效果至关重要。通过优化浸轧-蓝晒工艺,研究感光剂浓度、混合比例、曝光时间等因素对蓝晒效果的影响;利用扫描电镜、热重仪表征蓝晒棉织物形貌变化以及温度-质量变化关系,探讨普鲁士蓝沉积机理。结果表明:浸轧-蓝晒法棉织物最佳工艺为感光剂浓度140 g/L、混合比例VA∶VB=1∶1、曝光时间20 min;蓝晒棉织物表面均匀沉积大量固体颗粒,平均直径约(0.42±0.16)μm,且热重分析残渣率提升至14.22%,表明普鲁士蓝经过浸轧-蓝晒工艺成功沉积于棉织物表面;蓝晒棉织物强力损失约24.5%,伸长率无明显变化,耐水洗牢度4级,满足服用要求。Cyanotype photography is a manual printing technology that uses iron salt as a sensitizer via ultraviolet exposure to develop photos or patterns on the carrier. The obtained pattern presents a classic single blue tone, which is simple, elegant and long lasting, and the pattern is widely used in engineering drawings, decorative wall paintings and cultural and creative goods. However, due to its excessive dependence on traditional handwork and low production efficiency, it is difficult to be applied in large quantities of traditional textiles, such as household and clothing textiles. In order to expand the application of cyanotype photography technology in the textile field, textile researchers have made some attempts to replace photo paper with traditional textile fabrics and try to transplant cyanotype photography technology as a printing and dyeing technology to the textile printing and dyeing industry, and have made some progress. However, these studies mostly use traditional manual cyanotype processes, which have low efficiency and large differences in the cyanotype effects of different textiles, limiting their applications in the field of textiles and clothing.In order to clarify the influence of wettability on the carrier’s cyanotype effects, cotton, linen and silk are used as carriers, and their cyanotype effects are evaluated by the apparent color yield K/S values. The reasons for color difference are analyzed by sensitizer diffusion and cyanotype experiments. In order to improve the uniformity of photosensitizer agents on the fabric surface and realize batch production, we attempt to combine the traditional dip-padding process with the cyanotype process. Parameters, like photosensitizer concentration, mixing ratio and exposure time, are optimized and investigated to evaluate the feasibility of dip-padding and cyanotype method. SEM and TG analyzer are applied to characterize the morphological investigations and temperature-mass change relationship of the Prussian blue(PB)-load cotton fabric, followed by
