Abstract
The invention discloses an environment-friendly dyeing technique of cotton fabrics by using reactive dyes. Silane-coupling-agent-modified beta-cyclodextrin and a dispersing agent are utilized to help the inorganic alkali with fixation, so the color fixative has favorable fixation effect; and only soda ash is used without the need for any strong alkali, so the environmental hazard is small. No organic solvent is used in the whole dyeing process, so the technique does small harm to the human body and environment. The dye solution can be recovered and reutilized, thereby satisfying the national requirements for the strategy of sustainable development. The fixation effect is favorable, the dye-uptake rate can reach 95% or above, and the fixation rate can reach 90% or above.
Description
Technical field
The present invention relates to textile technology field, the environmental protection dyeing to bafta for more particularly, to a kind of reactive dye.
Background technology
Reactive dye can give fabric excellent wet colour fastness with cellulose fibre with Covalent bonding together, in addition its
Bright in colour, chromatograph is complete, becomes the most important dye of cellulose dyeing.Reactive dye are general in the basic conditions
Anchor on cotton, the hydroxide ion oh- in dye liquor also can occur necleophilic reaction with dyestuff, generates hydrolised dye, thus reducing
The degree of fixation (degree of fixation is normally only 50%～80%) of dyestuff.Hydrolised dye can not be reacted with cotton, the affinity to fiber
Very little, for obtaining the dyeing product of high humidity fastness it is necessary in the washing process stage by its eccysis, washing need to consume a large amount of water, lead
Blowdown flow rate and pollutional load is caused to increase.
Carried out numerous studies work in terms of improving the degree of fixation of dyestuff in recent years, such as using high direct outside domestic scholars
Property and high colour-fast rate multi-active base dyestuff, under low alkalinity or neutrallty condition dyeing, using the new work such as short liquor ratio and cold pad--batch
Skill, addition neutral electrolyte promote dye, with cross-linking agent, fabric are carried out dyeing front pretreatment, adopt cation or reactive fixing agent
Fixation etc..High direct and high colour-fast rate dyestuff is difficult by eccysis after hydrolyzing, and can affect dyefastness and dyeing uniformity；Low
Under alkali or neutrallty condition, dyeing need to be developed new dyestuff or be changed dyeing, such as rise high-temperature and increase electrolyte concentration；
Cold-stacking dyeing technology can make dye utilization rate improve 10%～15%, but the control of production link is required strict, coloured light controlled
Property poor, sodium silicate residual easily causes the defects such as fabric feeling is partially hard, tearing brute force declines；Low bath ratio dyeing can reduce the use of salt
Amount and raising dyestuff dye-uptake, but the requirement to equipment is higher；The a large amount of use of neutral electrolyte easily causes salt pollution；Fabric is pre-
Process modification and there is preferable wet colour fastness, but coloured light can dimmed, light fastness decline；Can be increased using cationic fixing agent and knit
The dye level of thing, but its fastness to wet rubbing can be reduced；It is still inadequate then to there is release formaldehyde, fastness to wet rubbing in reactive fixing agent
The problems such as ideal, changes of shade.
Content of the invention
The technical problem being existed based on background technology, the present invention proposes a kind of reactive dye and the environmental protection of bafta is dyeed
Technique.
A kind of environmental protection dyeing to bafta for reactive dye, comprises the following steps:
A, reactive dye are added to the water, obtain reactive dye dye liquor；
B, will bleaching after bafta put into above-mentioned reactive dye dye liquor in, bath raio be 1:(10-20), add dispersant a, then
It is warming up to 85-90 DEG C with the speed of 3-5 DEG C/min and be incubated 45-60min；
C, dye liquor is discharged and makes fabric liquid carrying rate be reduced to 100-200%, and add boiling water, soda, dispersant b and modified β-
Cyclodextrin, then be warming up to 100 DEG C with the speed of 1-2 DEG C/min and be incubated 15-20min；
D, insulation terminate after by fabric washing, soap, wash, drying, you can.
Preferably, described reactive dye are difluoro one chloropyrimide type reactive dye.
Preferably, in the dye liquor of described step a, the weight percent concentration of reactive dye is 2-10%.
Preferably, in described step b, dispersant a is glycerol.
Preferably, in described step c, the dye liquor of discharge can reuse.
Preferably, in described step c, dispersant b is section peaceful wetting agent hydropalat875.
Preferably, in described step c, described modified beta-schardinger dextrin-is through silane coupler modified.
The present invention assists inorganic base to carry out fixation by silane coupler modified beta-schardinger dextrin-and dispersant, the consolidating of color fixing agent
Color effect is good, and need not add highly basic, and using soda, the harm to environment is little.
Compared to traditional scheme, this programme has the beneficial effect that one is that the present invention has not used in whole dyeing course
Machine solvent, the hazardness to human body and environment is little；Two is can to recycle and reuse dye liquor, meets national sustainable development war
Slightly require；Three is that colour fixation is good, and dye-uptake can reach more than 95%, and degree of fixation can also reach more than 90%.
