Activated yellow dye composition

Abstract

An activated yellow dye composition comprises, in weight percentage, 1-99% of component A, 1-99% of component B and 0-45% of additives. The component A is selected from at least one of compounds as shown in a formula (I), and the component B is selected from at least one of compounds as shown in a formula (II). In the formula (I) and the formula (I), R<1> and R<2> are independent of each other and are C1-C4 alkyl or amidogen, and Y<1> and Y<2> are independent of each other and are -CH=CH2 or -C2H4OSO3H. The activated yellow dye composition has the advantages of high color fixing rate, good compatibility, easiness in washing and excellent washing color fastness when being used for textile printing.

Description

(1) Technical field [0001] The invention relates to a reactive yellow dye composition, in particular to a reactive yellow dye composition with excellent lifting power, easy water washing and stable dyeing performance. (2) Background technology [0002] C.I. Reactive Yellow 145 is an important reactive dye species, which contains two different reactive groups, namely monochloro-s-triazine group and β-hydroxyethyl sulfone sulfate group. The migration of the dye is 5 grades, the neutral whitening of 1 / 1 standard depth is 5 grades, and the basic whitening is 3-4 grades. It can be used for the dyeing of cotton and viscose fibers (exhaustion method, cold pad batch roll dyeing, continuous pad dyeing), also suitable for printing of cotton and viscose fabrics (one-phase or two-phase method), and can also be used for one-bath dyeing of polyester / cotton and polyester / viscose blends (same-bath dyeing with disperse dyes) ). [0003] [0004] The color fixation rate of this dye is no...
