Description
(I) technical field
The invention relates to a blue-to-black disperse dye composition and a dye product.
(II) background of the invention
Spandex-containing stretch fabrics are very popular in domestic and foreign markets. The product has the advantages of high elasticity, excellent resilience, soft hand feeling, comfortable wearing, easy sweat absorption, no static electricity generation and the like. Disperse dyes are mainly adopted for dyeing the polyester/polyurethane elastic fabric, and because a plurality of disperse dyes have high affinity and good dyeability to spandex, the disperse dyes are seriously infected with the spandex. During the fastness test, disperse dyes stained on spandex are easy to migrate out of the fiber, and the wet treatment fastness of the terylene/spandex textile is influenced. Many disperse dyes have good fastness to rubbing, washing and light on terylene, but the fastness on spandex can only reach a medium level, so that products with high requirements on the fastness have a great problem in dyeing processing. The prior document CN106497140A and the like provides a blue-black series dye composition excellent in various fastness properties, but there is still room for further improvement.
