Abstract

The invention discloses a preparation method of a fluorescent yellow polyester-cotton fabric. A carrier of reducing a polyester dyeing temperature is added in dyeing bath of disperse fluorescent yellow 10GN and active fluorescent yellow FL of the polyester-cotton fabric, so that the dyeing temperature of the polyester disperse fluorescent yellow 10GN is reduced, and most hydrolysis of reactive dyes under a high-temperature condition is prevented; and a dyeing method of fixing the active fluorescent yellow FL on cottons after dyeing the disperse fluorescent yellow 10GN on polyesters is adopted, so that all quality indexes of the dyed polyester-cotton fabric are accordant with that of the dyed fabric of a two-bath two-step method. The fluorescent dyeing is performed for the polyester-cotton fabric by adopting a one-bath one-step dyeing process, so that the production cost is reduced, and the quality of the obtained product is accordant with that of the two-bath two-step method, and satisfies the requirements of European standards EN471.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, and relates to a method for one-bath dyeing of polyester-cotton blended or interwoven fabrics by using disperse fluorescent yellow 10GN and reactive fluorescent yellow FL, especially capable of realizing the rubbing fastness and hand feeling of polyester-cotton fluorescent yellow dyed fabrics Improvement, improve production efficiency, reduce production costs. Background technique [0002] Fluorescent dyes or fluorescent pigments are dyes that can strongly radiate fluorescence in the visible light range, and are widely used in various industries such as textiles, plastic dyeing, and printing pigments. With the improvement of people's economic level, fluorescent fabrics are widely popular in recent years because of their bright and eye-catching colors and unique and novel visual experience. Compared with traditional dyes, fluorescent dyes not only have the functions of safety and war...
