Abstract

The invention relates to a method for fluorescent staining of orlon, which belongs to the field of dye synthesis and textile dyeing. Stilbazole salt is taken as a cation fluorescent dye, 0.2 and 2.5 percent owf fluorescent dye, 0.5g / L Peregal 0, a 1.0 percent owf leveling agent and 4g / L glauber salt are mixed to prepare a dye solution, acetic acid and a sodium acetate buffer solution are used to adjust the pH value of the dye solution to 5, and the dyeing processing with the dyeing bath ratio of 100 to 1 is performed to obtain a fluorescent orlon fabric. The stilbazole salt provided by the method has simple synthesis reaction, has relative flexibility in molecular design and assembly, and also has good linear optical performance and non-linear optical performance; and under specific dye bath concentration, the dyed orlon fabric satisfies the coordinate range of orange color stipulated in European EN471 standard High-visibility Warning Clothing for Professional Use-Test Methods (2003).

Description

technical field

[0001] The invention relates to the dyeing application of a cationic fluorescent dye on acrylic fiber, in particular to the dyeing application of a styrene pyridinium salt derivative as a cationic dye on acrylic fiber, and belongs to the fields of dye synthesis and textile dyeing. Background technique

[0002] The visual effect of fluorescent dyes includes both the color produced after selective absorption of visible light and the fluorescence emitted by them. It is a functional dye, which not only has the coloring properties of conventional dyes, but also emits fluorescence, which improves the saturation and vividness of fabrics. The earliest fluorescent dyes used in textiles are rhodin red and its derivatives, which can be used in the dyeing of silk, polyester, nylon, acrylic and other textile fibers to obtain brightly colored fabrics. At present, most of the fluorescent dyes for textiles on the market are disperse dyes, which are mainly used to dye polyes...
