CN101463569B - Post-mercerizing resistant active black dye for cellulose fibre - Google Patents

Abstract

The invention relates to a post-mercerizing resisting active black dye used for cellulose fiber, consisting of Color Index C.I. active black5, C.I. active blue222, C.I. active blue194, C.I. active red195, C.I. active yellow145, sodium sulphate, cosolvent and dedusting oil; wherein, the percentage composition of the invention is as follows: 13-16% of C.I. active black5, 12-15% of C.I. active blue222, 10-14% of C.I. active blue194, 2-3% of active red195, 1-3% of C.I. active yellow145, 30-40% of sodium sulphate, 17-25% of cosolvent and 0.2-1% of dedusting oil; the post-mercerizing resisting active black dye of the invention has the effects that the color change of the cellulose fiber before and after alkaline mercerizing is obviously alleviated and meanwhile staining is reduced.

Description

The reactive black dye of cellulose fiber Wesy post-mercerizing resistant

Technical field

The present invention relates to a kind of black dyestuff, relate in particular to the reactive black dye of a kind of cellulose fiber Wesy post-mercerizing resistant.

Background technology

Cellulose fibre sometimes need be again through the concentrated base mercerising after with reactive dyeing, and look became before and after the dyestuff of alkali resistance difference can cause mercerising, and different colors can be infected with mutually on the fiber simultaneously.Warm type REACTIVE DYES alkali resistance is not high in most of 60 ℃; Though 80 ℃ of middle warm types of High Temperature Type Reactive Dyes alkali resistance are good, the dyestuff dye-uptake is not as middle warm type REACTIVE DYES, and 80 ℃ of dyeing need to consume the more energy with 60 ℃ of dyeing relatively.

Summary of the invention

The technical issues that need to address of the present invention have provided the reactive black dye of a kind of cellulose fiber Wesy post-mercerizing resistant, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

The present invention is made up of Color Index C.I. reactive black 5, C.I. Reactive Blue 222, C.I. active blue 19 4, C.I. REACTIVE Red 195, C.I. REACTIVE Yellow 145, glauber salt, cosolvent, dust laying oil; Its percentage composition is: C.I. reactive black 5 13-16%, C.I. Reactive Blue 222 12-15%, C.I. active blue 19 410-14%, C.I. REACTIVE Red 195 2-3%, C.I. REACTIVE Yellow 145 1-3%, glauber salt 30-40%, cosolvent 17-25%, dust laying oil 0.2-1%.

Compared with prior art, the invention has the beneficial effects as follows: can significantly alleviate cellulose fibre and become, reduce staining simultaneously at alkali mercerized front and back look.

The specific embodiment

Below in conjunction with the specific embodiment the present invention is described in further detail:

Embodiment 1

Percentage composition of the present invention is: C.I. reactive black 5 15%, C.I. Reactive Blue 222 13%, C.I. active blue 19 4 12%, C.I. REACTIVE Red 195 2.8%, C.I. REACTIVE Yellow 145 1.7%, glauber salt 30%, cosolvent 25%, dust laying oil 0.5%.

Embodiment 2

Percentage composition of the present invention is: .C.I. reactive black 5 16%, C.I. Reactive Blue 222 14%, C.I. active blue 19 4 13%, C.I. REACTIVE Red 195 2.2%, C.I. REACTIVE Yellow 145 2.3%, glauber salt 32%, cosolvent 20%, dust laying oil 0.5%.

The raw material that the present invention adopts can both have been bought on market.

Dyestuff in the above-mentioned raw materials all is the reasonable dyestuff of resistance to acids and bases, uses such prescription can strengthen the dyestuff ion and urgees to dye ability, utilizes the different look of each dyestuff to become simultaneously and generation form and aspect complementation, thereby reaches the stable of mercerising front and back coloured light.

Color Index is the meaning of " Colour index number ", and it is international dyestuff title.Glauber salt is a sodium sulphate,, cosolvent is that lignosulfonates, dust laying oil are white kerosene.These three kinds of typical additives that composition is the prior art REACTIVE DYES.Glauber salt plays water sorption, prevents that dyestuff from becoming damp and rotten; Cosolvent can help dyestuff to dissolve fast; Dust laying oil can be avoided dust from flying when dyestuff is carried.

Manufacture method of the present invention is: former dyestuff filter cake adds glauber salt, cosolvent and process heat water-soluble, grinds repeatedly and filters 48 hours, delivers to batch can, and spray drying adds dust laying oil and stirs finished product packing.The waste gas that produces in the spray drying is by cyclone dust removal, and bag filter gas filters, and discharges as fuel oil waste gas and dust.
