【摘要】 为研究蓝莓色素在家蚕丝染色及功能整理中的应用价值，以去离子水提取蓝莓果皮中的蓝莓色素，制得蓝莓色素提取液并对家蚕丝织物进行染色，研究染色工艺及媒染剂对染色性能及功能的影响。结果表明，蓝莓色素对家蚕丝织物染色的最优条件为pH 4.5、温度90℃、染色时间50 min;通过硫酸铝钾或硫酸亚铁媒染可显著改善颜色深度，其中硫酸亚铁预媒染色试样的K/S值最高，为8.59,且色牢度提升至3级。直接染色家蚕丝织物具有良好的pH响应特性，并具有作为酸碱指示材料的潜质。所有染色试样均显示出抗氧化及抗紫外线性能，其中直接染色试样的抗氧化性能最佳，硫酸亚铁预媒染样的抗紫外线性能最佳。该研究为开发具有光防护、抗氧化、pH响应特性功能的生态纺织品及医用纺织材料提供了理论参考。更多还原

【Abstract】 To explore the application value of blueberry pigment in dyeing and functional finishing of mulberry silk, blueberry pigment was extracted from fruit peels with deionized water. The resulting extract was used to dye mulberry silk fabric, with a focus on optimizing dyeing conditions and assessing the effects of mordants on color performance and functionality. The findings showed that the optimal dyeing conditions were pH 4.5, 90 ℃, and 50 min. Mordanting with aluminum potassium sulfate or ferrous sulfate significantly improved color depth, with ferrous sulfate pre-mordanted samples achieving the highest K/S value of 8.59 and a color fastness rating of 3. Direct-dyed silk fabric exhibited good pH-responsive properties, suggesting potential as an acid-base indicator. All dyed samples demonstrated antioxidant and UV-protective properties, with direct-dyed samples showing the best antioxidant performance and ferrous sulfate pre-mordanted samples offering superior UV resistance. This study provides a theoretical foundation for developing eco-friendly and medical textiles with light protection, antioxidant, and pH-responsive functionalities.更多还原
