摘　　要：为使染色后的荧光腈纶纱线既能保持良好的荧光效果,又能达到较为齐全的色谱,选用三原色阳离子染料荧光黄10GFF、艳红X-5GN和蓝X-GRRL,在最佳染色工艺条件下对荧光腈纶纱线进行拼色染色,同时采用一些荧光增白剂和阳离子染料进行同浴增白染色。实验结果表明:在三原色染料的拼色染色时,采取合适的染料配比能使荧光腈纶纱线获得较为齐全的色谱;在荧光增白剂和阳离子染料同浴增白染色时,荧光增白剂TF-920可进一步提高荧光腈纶纱线的荧光效果。In order to achieve good fluorescent effect and wider chromatogram for dyed fluorescent acrylic yam, trichromatic cationic dyes such as Fluorescent Yellow 10GFF, Brilliant Red X-5GN and Blue X-GRRL were used in combination dyeing of acrylic yam with the optimal dyeing process. Meanwhile, one-bath process of whitening with fluorescent whitening agents and dyeing with cationic dyes was carried out on acrylic yam. The experimental results show that more complete chromatogram of fluorescent acrylic yam can be obtained with suitable proportion of mixed dyestuff in combination dyeing. TF-920, a fluorescent whitening agent, can further raise the fluorescence effect of acrylic yam during one-bath process of whitening and dyeing.
