摘　　要：以最为常见的黄色高可视警示服为例,采用分散荧光黄10G和涂料荧光黄对涤棉混纺针织物进行二浴法染色,讨论了分散染料质量分数、涂料质量浓度、染色温度、染色时间及染浴pH值对染色织物K/S值及荧光性能的影响。优化的染色工艺为:采用分散荧光黄10G和涂料荧光黄对涤棉混纺织物染色,分散荧光黄染料质量分数3%(omf),染色温度125℃,染色时间25 min,染浴pH值4;荧光涂料黄质量浓度5 g/L,染色温度65 t,染色时间30 min。染色后涤棉混纺织物的亮度系数β和色度x-y值均能满足国家标准要求,色牢度达到4级。Taking the most common yellow high-visibility warning clothing as an example,two-bath dyeing of polyester/cotton blended knitted fabrics with Disperse Fluorescent Yellow 10G and Pigment Fluorescent Yellow is carried out,and the effects of mass fraction of disperse dyes,pigment concentration,dyeing temperature,dyeing time and pH value of the dye bath on K/S value and fluorescence properties of dyed fabrics are discussed.The optimized dyeing process is:the mass fraction of Disperse Fluorescent Yellow 10G is 3%(omf),dyeing temperature is 125℃,dyeing time is 25 min,dyeing bath pH value is 4;the mass concentration of Pigment Fluorescent Yellow is 5 g/L,dyeing temperature is 65℃,dyeing time is 30 min.The luminanee factor p and chromaticity x-y value of dyed polyester/cotton blended fabric can meet the requirements of national standards,and the color fastness reaches Level 4.
