Abstract
The invention provides a reactive dye micro-extraction dyeing method. The method comprises the following steps of dissolving reactive dye extract in acetone, adding oleic acid into the solution, carrying out ultrasonic treatment to obtain a transparent solution, carrying out reduced pressure pumping filtration on the solution to obtain oleic acid-coated reactive dye powder, adding the oleic acid-coated reactive dye powder into isooctane, carrying out ultrasonic dispersion, diluting the prepared dye concentrated solution by isooctane, putting a cotton fabric padded with an alkali agent-containing solution into the dye solution, carrying out oscillation heating dyeing and carrying out heating dye fixation. The reactive dye is dissolved in the oil phase so that a water use amount is reduced and is 2-5% the common water use amount and thus water saving is promoted. The reactive dye is extracted by a water phase on the surface of the fabric and a small amount of the reactive dye is hydrolyzed because of a small amount of water. The extracted dye on the surface of the fabric has a high concentration, a high dye concentration gradient is formed, and a color yield of the fabric is high so that salt-addition dyeing accelerating is not needed.
Description
Technical field
The present invention relates to a kind of colouring method, be specifically related to a kind of micro-extraction colouring method of REACTIVE DYES.
Background technology
REACTIVE DYES for textile dyeing has water-soluble, and existing staining technique is dissolved in the aqueous solution by REACTIVE DYES, then directly dyes to textiles.Such as, although water has many advantages as the dyeing medium of cheapness, dissolving dye, swollen fiber etc., REACTIVE DYES is easily hydrolyzed in aqueous, causes waste, and dyeing needs to consume large water gaging, not only polluted source but also bring many ecological problems.Estimate according to correlative study unit, often dye in traditional dyeing course 1 ton of fiber, approximately consumes 30 ~ 50 tons of water.China's textile printing and dyeing industry day wastewater discharge 3 × 10
7~ 5 × 10
7cubic meter, reaches 20 billion cubic meters every year.Recently, the focus of research is become as the supercritical CO 2 dyeing of the cleaning dye techniques such as have no water or little water, reverse micro emulsion decoration method.
Supercritical CO 2 dyeing utilizes in the supercritical state, and supercritical carbon dioxide is medium, makes dissolving dyestuff wherein contaminates on fabric.The method shortcoming is that carbon dioxide is nonpolar molecule, and for routine is that the REACTIVE DYES of medium does not have good dissolubility with water; Mainly be suitable for dyeing hydrophobic fiber as terylene etc., but for hydrophilic fibre as cotton, Color is bad.
In reverse micro emulsion decoration method, microemulsion is the dispersion of a kind of isotropism, appearance transparent, and microemulsion droplets diameter is at 10 ~ 100nm, and drop is dispersed in system, water-soluble dye is solubilized in oil phase with Water-In-Oil form, and then realizes the dyeing to textiles.The method water requirement is less, but needs more surfactant to build the cyst wall of drop, is unfavorable for the recovery of dyestuff, too increases dye liquor and enters dye to the difficulty on fabric.
Summary of the invention
One of the object of the invention is the micro-extraction colouring method providing a kind of REACTIVE DYES, and this colouring method use water is few, makes textiles tinctorial yield high, does not need the short dye of salt.
To achieve these goals, the present invention takes following technical scheme:
