Problems solved by technology
Generally, disperse dyes with high light fastness have a heavy staining effect on spandex, and are easy to adhere to the surface of spandex. They are easy to fade after washing, and the fastness is difficult to meet the application requirements. Generally, disperse dyes with high water washability are mostly azo or Heterocyclic structure, poor light fastness

The invention relates to a blue disperse dye composition with high washing fastness and high light fastness. The dye is composed of the following components in percentage by weight: 0-70% of dye monomer A, 0-80% of dye monomer B, 0-40% of dye monomer C, 0-10% of dye monomer D, 0-20% of dye monomer E and the balance of assistant. The disperse dye composition has quite high light fastness and washing fastness, the difficulty that the disperse dye can not take into account of the light fastness and the washing fastness is solved, meanwhile, the dye has good uniform dyeing property and excellent other color fastness, so that the blue disperse dye composition is a high-grade dye suitable for automobiles and outdoor sports series.
Description
technical field [0001] The invention relates to a blue disperse dye composition, in particular to a blue disperse dye composition with high washing and light fastness, which is suitable for printing and dyeing of hydrophobic fiber materials. Background technique [0002] In recent years, with the improvement of people's living standards, people have higher and higher requirements for the comfort of clothing fabrics, and at the same time, they have higher and higher requirements for the color fastness of textiles. For example, some outdoor sports fabrics not only require dyes with high washing fastness, but also good light fastness. Generally, disperse dyes with high light fastness have a heavy staining effect on spandex, and are easy to adhere to the surface of spandex. They are easy to fade after washing, and the fastness is difficult to meet the application requirements. Generally, disperse dyes with high water washability are mostly azo or Heterocyclic structure, poor li...
