蚕丝/Lyocell交织物双活性基染料同色染色

Tone- on- Tone Dyeing of Silk/Lyocell Blends with Bifunctional Reactive Dyes

用经筛选的双活性基染料（如Megafix B和BES以及CibacronFN）对蚕丝/Lyocell（45:55）交织物对迸行染色,可获得较好的同色性。

Silk/Lyocell blends could be dyed to solid shades by screening bifunctional dyes. For the dyes of dyeing silk darker in conventional process, the blends could be dyed to solid shades through the pre - addition of alkali and the pretreatment with a retard agent. For the dyes of dyeing Lyocell darker in conventional process, the blends could be dyed to solid shades through the modification with a cationic agent. ....................................................................................................................
