Abstract
The invention discloses blue disperse dyestuff compounds as shown in a formula (I) which is described in the specification, a dye composition, a dye product and application thereof. The dark blue to black disperse dyestuff composition contains a dye component A, a dye component B and / or a dye component C, wherein the dye component A is one or more selected from the compounds as shown in the formula (I), the dye component B is one or more selected from compounds as shown in a formula (II) which is described in the specification, the dye component C is one or more selected from compounds as shown in a formula (III) which is described in the specification, and the contents of the dye component B and the dye component C are not zero at the same time. The dye product contains the blue disperse dyestuff compounds or the dark blue to black disperse dyestuff composition. The invention also provides application of the blue disperse dyestuff compounds in dyeing or printing of hydrophobic fibrous materials. The blue disperse dyestuff compounds are applicable to small-bath ratio dyeing, have various excellent fastnesses and a wide pH value tolerance scope, can realize dyeing in a dye bath with a pH value of 3.5 to 14 and shows outstanding resistance to alkali.
Description
[0001] (1) Technical field [0002] The invention relates to a blue disperse dye compound, a dark blue to black disperse dye composition and its dye product and its application in dyeing or printing of hydrophobic fiber materials (especially polyester and its blended fabric materials). [0003] (2) Background technology [0004] Disperse dyes are applied under high temperature (125°C-135°C) conditions, and there is a problem of chemical stability. When the pH value of the dyeing bath is in the range of 3 to 6, the acid resistance and stability are good, and it is not easy to cause obvious color difference. However, when the pH of the dye bath is greater than 6, many commonly used disperse dyes will undergo hydrolysis reactions, making the color lighter, the color and light changing, and the alkali resistance stability is very poor. [0005] In the traditional polyester fabric dyeing and finishing process, the pretreatment desizing, refining (including relaxation) and alkali re...
