Yellow disperse dye with high light fastness

Abstract

The invention relates to a yellow disperse dye with high light fastness for a polyester fiber. The dye consists of the following components in percentage by weight: 50 to 92 percent of dye monomer A, 5 to 45 percent of dye monomer B, 1 to 10 percent of dye monomer C and the balance of auxiliary agents. The disperse dye can be used for dying products such as automobile interior fabrics made of thepolyester fiber and the like. By the yellow disperse dye, the phenomenon that the fabrics fades because of sunlight irradiation can be avoided to the greatest extent, so that the light fastness of the dyed fabrics can be greatly improved, the level dyeing performance is high and other various color fastnesses can be optimal.

Description

technical field [0001] The invention relates to a yellow disperse dye, in particular to a yellow disperse dye (disperse yellow HLF-E) used for high light fastness of polyester fibers. Background technique [0002] At present, in response to the increase of outdoor sports and the growth of car sales, there are more and more varieties of automotive interior fabric products, and these items are usually exposed to sunlight at high temperatures, which are prone to color fading and are difficult to guarantee. It maintains good color for a long time, so the requirements for light fastness are getting higher and higher. How to reduce the fading of fabrics after sunlight exposure has become a key research topic. [0003] Therefore, as an understanding of the above situation, it is necessary to use dyes with particularly good light fastness to dye polyester fibers used in outdoor products, but in the past there were few yellow disperse dyes with particularly good light fastness to dye...
