Reactive yellow dye for ink jet printing and preparation method and application thereof

The invention relates to a reactive yellow dye for ink jet printing and a preparation method and application thereof, belonging to the field of fine chemical industry. The reactive yellow dye shown inthe formula(I)has higher solubility, good fixation rate and color fastness, high stability after dyeing and bright color light, can be widely applied to dip dyeing, pad dyeing and ink jet printing ofcotton, hemp and artificial cotton fiber fabrics, has low production cost, and can be popularized and applied on a large scale.

Reactive dye, and composition, preparation method and application thereof

The invention discloses a reactive dye, and a composition, a preparation method and an application thereof. The preparation method for a compound as shown in a formula (1) described in the specification comprises the following steps: subjecting a compound as shown in a formula (2) described in the specification to a condensation reaction with compounds as shown in a formula (3) and/or a formula (4) in water under the condition that the pH value is 6.5 to 7.5 so as to prepare the compound as shown in the formula (1). The reactive dye provided by the invention has optimums like complete chromatography of a monochloro s-triazine reactive dye, excellent fastness indexes, no staining in white bottom and large solubility, has high fixation rate capable of reaching 80% or above, reduces the waste of a dye, is green and environment-friendly, reduces printing cost, and is more applicable to industrial production. The reactive dye provided by the invention is applicable to printing, dip dyeing and continuous dyeing on fibers like cotton and hemp and protein fibers like wool and silk, and has simple preparation method, cheap raw materials and significant economic benefits and environmental benefits.

Reactive dyestuffs with alkylthio group and beta-sulfatoethysulfone group

The present invention provides a reactive dyestuff with an alkylthio group and a β-sulfatoethylsulfone group, which is represented by formula (I), wherein D, R, R1, R2, R3, R4, Q, x, and y are defined the same as the specification.

Novel reactive yellow dye compounds and mixture thereof

Provided is a reactive dye mixture, comprising (i) one or more reactive dyes represented by Formula 1, and (ii) one or more reactive dyes represented by Formula 2: The dye mixture of the present invention can realize a color that is difficult to be achieved by a single dye when dyeing a fiber material containing nitrogen or hydroxyl group, particularly a cellulose fiber material, exhibits a superior absorptivity and fixability, particularly very high light fastness and wet fastness, and thus provides a variety of balanced physical properties which are required in dyeing.

Fiber reactive dyestuffs

A fiber reactive dyestuff of the following formula (I) wherein the definition of D, R, R1, R2, X and Z have the same meaning as given in the specification. The fiber reactive dyestuff of the present invention is suitable for dyeing and printing on cellulose fiber or fiber materials containing cellulose. Dyed material with various excellent properties in dyed color can be obtained, showing especially outstanding performance in the property of wash fastness, build-up and chlorine fastness.

Environmental protection series of reactive dyestuffs and their use

An environmental protection reactive dyestuff of the following formula (I) is disclosed, wherein R1, R2, D, M are defined as in the specification. The dyestuff of the invention is distinguished by a high fixation and a very good build-up. It is distinguished also by a green environmental protection and a low salt, a low base, a high exhaustion, non-contain heavy metal and halogen atoms, and it has fiber-reactive properties and is very highly suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, synthetic cotton, hemp, and synthetic hemp, or amide containing fibers such as wool and nylon.

Triazinylaninlino-disazo dyes, methods of preparing them and their use for dyeing and printing fiber materials
