Abstract
The invention relates to a cotton fabric deep-dyeing method. The cotton fabric deep-dyeing method comprises the following steps: immersing a cotton fabric into an ionic liquid, increasing the temperature to 80-100 DEG C, and performing pretreatment for 1-20 min to obtain the pre-treated cotton fabric, wherein the proportion of the cotton fabric and the ionic liquid is (1:1)-(1:5); taking out the pre-treated cotton fabric, washing and soaking with hot water, and then washing and soaking with cold water to obtain the water-washed cotton fabric; placing the water-washed cotton fabric into a dye bath, dyeing for 15-60 min at a temperature of 85-95 DEG C, and washing with water. The cotton fabric deep-dyeing method is convenient and simple to operate, and the ionic liquid in the washing liquid can be recycled and reutilized, so that carbon emission reduction, consumption reduction and cost reduction are realized.
Description
Technical field
The invention belongs to fabric dyeing method field, particularly a kind of COTTON FABRIC increases deep dyed color method.
Background technology
REACTIVE DYES has the advantages such as chromatogram is complete, bright in colour, price is low, dyeing is simple, good level-dyeing property, is one of dyestuff being most widely used in COTTON FABRIC dyeing and finishing processing.When COTTON FABRIC is used reactive dyeing, because the hydroxyl on cotton fiber macromolecule side chain is hydrolyzed in the aqueous solution, make cotton fiber show elecrtonegativity, after REACTIVE DYES is water-soluble, because dye matrix is electronegative, dyestuff is very weak to the adsorptivity of fiber like this.In traditional dyeing, by REACTIVE DYES, must add a large amount of salt as accelerant during to cotton fabric dyeing process, to improve dye uptake and the tinctorial yield of dyestuff.But, because using a large amount of salt, add that REACTIVE DYES is low to the dye-uptake of cotton fiber, cause in dyeing residual liquid and contain a large amount of salt and pigment, such dyeing residual liquid, can cause serious environmental pollution after discharge; In addition, REACTIVE DYES is in dyeing course, and dyestuff in water, hydrolysis can occur and lose the respond with fiber, thereby dye utilization rate is low, and dyeing waste colourity is high.Therefore, cotton fiber is carried out to chemical modification, can improve the dyeability of cotton fiber to REACTIVE DYES, improve tinctorial yield, change traditional dyeing technique, save dyestuff.
Cotton fiber is carried out cation-modified, it increases dark basic principle is the electronegativity that changes fabric face, reduces the electrostatic repulsion of fiber and anionic dye, and what make that fiber carries out the absorption of dyestuff and reaction is easier, thereby improves dye-uptake and degree of fixation.The cotton fiber of cationization is dissociated into negative oxygen ion except original hydroxyl salt of weak acid, simultaneously also with CATION (positive charge), just because of cationic existence, not only can eliminate anion on fiber and the electric double layer effect of dyestuff anion, and can increase the electrostatic attraction of fiber to anionic dye, increase the affinity to dyestuff.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of COTTON FABRIC and increases deep dyed color method, and the method method of operating is convenient, and formula is simple, can save other auxiliary agent costs.
A kind of COTTON FABRIC of the present invention increases deep dyed color method, comprising:
