真丝绸的增深染色

Real Silks Deep Dyeing

通过ＺＳＤ型真丝绸染色增深剂对真丝绸常用的酸性、直接和活性染料上染率试验，以及染色绸的表观色泽深度和色牢度测试，证实该增深剂在染深、匀染和色牢度等方面具有良好的效果，节约染料１０％～７０％，使用方便。文中对该增深剂的增深原理进行了探讨，对其有关指标与常规染色进行了比较。

The experiment of dye-uptake of real silks dyeing with acid,direct and reactive dyes in presence of darkening agent ZDS, and tests of the dyed silk apparent depth and colour fastness indicate that the darkening agent is excellent in its deep dyeing, even dyeing and colour fastness, with a dye consumption reduced by 10-70%. Investigations are herein made on its darkening principle and comparisons made of relevant indices and common dyeing.
