摘　　要：结合标准GB/T 7573—2009中的测试方法，分析纺织品水萃取液pH值测试的影响因素，包括萃取介质及其酸碱度、萃取温度、萃取时间、萃取振荡速率等。结果表明：在pH值测定中，萃取介质酸碱度对测试结果影响最大，随后是萃取介质、萃取温度、萃取时间、振荡速率所带来的影响。结合工作实际，萃取介质建议选择0.1 mol/L的氯化钾溶液，萃取介质酸碱度最好调节至中性，萃取温度控制在20～25℃范围内，萃取时间选择在1～2 h，振荡速率调节至60～90次/min。Combined with the inspection standards GB/T 7573—2009, this paper analyzes the effects of the aqueous extract pH value, including extracting medium, extracted liquid pH value, extraction temperature, extrac-tion time, and oscillation rate. The results show that, extracted liquid pH value has the greatest effect on pH value of the test result, followed by extraction medium, extraction temperature, extraction time and the oscillation rate. In daily work, The best conditions is that choosing 0.1 mol/L potassium chloride solution as extraction medium, ad-justing extraction medium pH to neutral, controlling best extraction temperature 20～25 ℃, choosing extraction time of 1～2 hours, regulating oscillation speed to 60～90 times per minute.
