Description
Technical field
The present invention is a kind of dyeing method, in particular to a kind of production technology of TR fabric stability dispersion dyeing pH value, is fitted
Used additives 2037 replace glacial acetic acid when for overflow dyeing machine disperse dyeing, make the production technology that dye liquor pH value is stable.
Background technique
Disperse dyes high temperature and pressure contaminates terylene, and Value in Dyeing Process should be controlled in faintly acid.In process of production, ice is generally used
Acetic acid is adjusted, and makes pH value control between 4.5-5.5；But in reality production, to the control of pH there is two be easy it is ignored
But particularly significant problem, the i.e. accuracy and stability of Value in Dyeing Process.
In dyeing course, acid and alkali substance can be brought into there are many factor, to make Value in Dyeing Process send out in dyeing course
It is raw to change.Such as:
Dyeing water might not be in neutrality；After heated, cooling, pH value is got higher；
Semi-products (especially containing cotton, viscous product, by alkali desizing or mercerizing process etc. before dyeing) to be contaminated usually band alkali；
The variation of pH value etc. of disperse dyes itself.
Glacial acetic acid is volatile, and it is poor to adjust Value in Dyeing Process stability with it；Dye bath pH value before heated may be adjusted to 4.5-5.5
Between, and heat through dyeing, after cooling, dye liquor breaks through the processing range of pH=4.5-5.5；As it can be seen that being set up before dyeing
PH value, and not equal to the actual pH of dye bath in dyeing course.
Summary of the invention
The present invention mainly solves the deficiencies in the prior art, and providing a kind of can be effectively controlled disperse dyes dye baths
PH value reduces the artificial unstability for adjusting pH value, reduces a kind of TR fabric stability dispersion dye of the cylinder difference of disperse dyeing
The production technology of color pH value.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals:
A kind of production technology of TR fabric stability dispersion dyeing pH value, sequentially includes the following steps:
(1), sample cloth is chosen:
The T/R fabric sample cloth that a coupe degree is 80 meters or so is chosen, openpore door width 160cm, grammes per square metre 200g/ ㎡ contaminate navy；
The woven that T/R product is generally made of 65% polyester fiber and 35% viscous fiber；
(2), the selection of material is contaminated:
The selection of disperse dyes:
Disperse dyes can be divided into three classes:
(1), high temperature modification, S type: this kind of dye sublimation fastness is preferable, poor diffusivity；
(2), low form, E type: this kind of dye sublimation fastness is poor, and diffusivity is good, is suitble to exhaustion method dyeing, there is preferable level dyeing
Property；
(3), middle warm type, SE type: the kind between both the above；
A) to keep T/R fabrics cloth cover bright and clean, will generally singe processing after dye, and drying and shaping is wanted before singing, keeps cloth cover smooth,
Since setting temperature is higher, the preferable high temperature modification of heat sublimation fastness, S type dye are selected；
B) dyestuff that select dye uptake, colouring speed close, it is preferred to use three-primary colours；
The selection of auxiliary agent:
Adjust disperse dyes Value in Dyeing Process auxiliary agent:
Disperse dyes are weak acid dye, generally adjust pH value with glacial acetic acid, since glacial acetic acid is volatile, especially at high temperature,
It is easier to play, makes dye liquor partial neutral or meta-alkalescence, influence disperse dyes colouring；Even if be added buffer, also because dosage how much, pH
Value is varied；Select the auxiliary agent smaller in range using the pH stable in energy dye bath；
Reactive dyeing auxiliary agent:
A) anhydrous sodium sulphate: due to the difference of the manufacturer of anhydrous sodium sulphate, the content of sodium sulphate is also different in anhydrous sodium sulphate；It selects
Na2SO4 content is 97% or more, and pH value wants neutral or slightly biased alkali, can not meta-acid；Chloride ion cannot be contained, chloride ion is to stainless
Steel dyeing machine cylinder has stronger corrosivity；
B) color fixing agent: the color-fixing method of reactive dye generally has pure alternative alkaline process, substitute alkali to add Method of Soda and three kinds of hjolomorphism alkaline process；
Use soda ash for the color fixing agent of reactive dyeing process, to the pH value of dye bath, fiber color is more stable；Soda ash is generally wanted
Ask Na2CO3 content 90% or more；
