Dissipate the printing and dyeing that dyestuff is applied to polyester fiber.
Background technology
With the continuous improvement of environmental requirement, sensitization dyestuff has been gradually backed out market, if C.I. disperse yellows 23 are because of it
Dyeability is superior, and cheap application is relatively broad, but produces sensitization aromatic amine because it can be decomposed, and is classified as taboo by European Union
Do not used with dyestuff.Many existing Yellow environment-friendly disperse dyes of in the market, otherwise it is expensive, otherwise color fastness, carry
Liter property, compatibility can not substitute C.I. disperse yellows 23 completely.
Although has the Yellow disperse dye of some environment-friendly types in recent years, in patent CN1580133A, CN1974680A
Disclosed Yellow disperse dye is widely applied, but these Yellow disperse dyes with conventional blue 2BLN, red E-FB
Dyeing defect occurs when compatibility inconsistent situation, especially dyeing by jigger often occurring when being used as three primary colors.Cause
This, in the market is badly in need of a kind of Yellow environment-friendly disperse dye of high performance-price ratio, does not require nothing more than its compatibility and blue 2BLN, red E-FB
Matching, and dyestuff it is fast light, washing, distillation, perspiration fastness also to get well, to meet continually changing customer requirement.
