NOVEL REACTIVE DYESTUFF WITH N-ALKYLAMINO GROUP
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a novel reactive dyestuff with a
N-alkylamino bridge group and, more particularly, to a novel reactive
dyestuff suitable for exhaust dyeing, cold batch-up dyeing, continuous
dyeing, printing and digital spray printing materials that contain hydroxyl
group or polyamine fibers.
2. Description of Related Art
An.azo dyestuff, where the chromophore thereof is composed of azo
components and coupling components, can be widely employed and used as
a reactive dyestuff for heavy color dyeing, such as red, navy, blue, black and
so on, owing to its broad color gamut and high extinction coefficient.
Currently, the development of reactive dye is moving towards warm
dyeing, higher fixation and better build up to meet the economic demands.
Since sulphato-ethyl-sulphone (SES) reactive groups cannot meet
customers' demands for cotton dyeing due to their poor resistance to
alkaline, monochloro triazine (MCT) type dyestuffs are usually used for
dyeing. However, the use of monochloro triazine (MCT) type dyestuffs in
»
dyeing consumes more energy and the dyed materials exhibit poor water
fastness.
For example, in U. S. Pat. No. 5,552,532, U. S. Pat. No. 5,931,975,
U. S. Pat. No. 5,717,078, U. S. Pat. No. 5,837,827 and U. S. Pat. No.
5,831,038, such dyestuffs are developed.

However, the build up, hue-shift, levelness and wash fastness of the
aforementioned novel dyestuffs cannot meet the market requirements.
Thereby, it is desirable to improve the aforementioned properties.

N-alkylamino bridge group, which exhibits the properties of improved
fixation yield, excellent build up, high wash fastness and excellent wet
fastness while dyeing cellulose fibers.

For convenience in description, the compound is expressed as free
acid in the specification. When produced or used, the dyestuffs of the

suitable for the present invention may be the alkaline metal salts, alkaline
earth metal salts, ammonium salts or organic amine salts; preferably, the
salts are sodium salts, potassium salts, lithium salts, ammonium salts or
triethanolamine salts.
The dyestuffs according to the present invention can be prepared by
a conventional method. The synthetic routine for preparing the dyestuffs is
not strictly limited. For example, a chromophore may be first prepared and
then a desired dyestuff is synthesized, or a chromophore may be
synthesized in the process for preparing a dyestuff.
The dyestuffs of the present invention can be applied to dye and
print many kinds of fiber materials, particularly cellulose fiber materials
and cellulose-included fiber materials. The examples of the fiber materials
are not limited. It can be natural or regenerated cellulose fibers, such as
cotton, hemp, linen, jute, ramie, mucilage rayon, as well as
cellulose-included fiber materials. The dyestuffs of the present invention

can also be applied to dye and print fiber blended fabrics containing
hydroxyl groups.
The dyestuffs of the present invention can be applied to the fiber
material and fixed on the fiber in various ways, particularly in the form of
aqueous dyestuff solutions and printing pastes. They can be applied to dye
and print cellulose fibers by exhaustion dyeing, continuous dyeing,
cold-pad-batch dyeing, printing or digital printing.
The dyeing or printing of the present invention can beproceeded by
the conventional and usually known method. For example, exhaustion
dyeing is applied by using separately or mixing the well-known inorganic
salts (e.g. sodium sulfate and sodium chloride) and acid-binding agents (e.g.
sodium carbonate, sodium hydroxide). The amount of inorganic salts and
alkali does not matter. The inorganic salts and alkali can be added either
once or several times into the dyeing bath through traditional methods. In
addition, dyeing assistant agents (such as a leveling agent, suspending agent
and so on) can be added according to conventional methods. The range of
dyeing temperature is from 40 °C to 90 °C. Preferably, the temperature for
dyeing is from 50 °C to 70 °C.
In the cold-pad-batch dyeing method, the material is padded by using
the well-known inorganic salts (e.g. sodium sulfate and sodium chloride)
and acid-binding agents (e.g. sodium carbonate, sodium hydroxide). The
padded fabric is rolled and stored at room temperature to allow dye fixation
to take place.
In the continuous dyeing method, two different methods exist. In the
single-bath pad dyeing method, the material is padded according to the
conventional method in the mixture of the well-known acid-binding agents

(e.g. sodium carbonate or sodium bicarbonate) and the pad liquid. The
resultant material is then dried and color fixed by baking or steaming.
In the two-bath pad dyeing method, the material is padded with a dye
liquid and then dealt by a known inorganic neutral salt (e.g., sodium sulfate
or sodium silicate). The dealt material is preferably dried and color-fixed by
baking or steaming in the usual manner.
In the textile printing method, such as the single printing method, the
material is printed by using printing paste containing the known
acid-binding agent (e.g., sodium bicarbonate) and is dried and color-fixed by
baking or steaming.
In the two-phase printing method, the material is dipped in a solution
containing inorganic neutral salt (e.g., sodium chloride) and the known
acid-binding agent (e.g., sodium hydroxide or sodium carbonate) in a high
temperature of 90°C or above to fix the color.
The dyeing or printing methods employed in the process of the
present invention are not limited to the above methods.
Other objects, advantages, and novel features of the invention will
become more apparent from the following detailed description when taken
in conjunction with the accompanying drawings.
