【摘要】 本文研究了Sirius Red F3B和C.I.Acid Yellow 23拼混染料在真丝绸上的着色量与丝胶含量之间的定量关系.采用三刺激值系统表色法表色,计算出试样与练白绸标样的色差值,通过色差值与练减率的标准曲线求得织物练减率.测定时间少于10min,误差小于0.5%更多还原

【Abstract】 On the silk fabrics, a qualitative relationship between the degumming loss percentageand the dye-uptake for the mixed dyes with Sirius Red F3B and C.I.Acid Yellow 23 is in-vestigated. With CIE colour designation, the colour deviation values for sample and stand-ard sample degumming fabrics were counted and the degumming loss percentage of samplewas found through the standard curve of colour deviation-values and degumming loss per-centage: The measured time of this method less than 10 mins, and errors less than 0.5%.更多还原
