Description
Technical field
The invention belongs to textile dyeing and printing technique technical field, more particularly to a kind of suitable viscose glue and nylon fibre composition
The high temperature of textile bathes dyeing entirely.
Background technology
Under normal circumstances, though viscose glue and polyamide fibre belong to staple fibre together, need with different technological temperatures, dyestuff, chemistry
Product realize the dyeing to respective fiber respectively.The former is similar to the dyeing behavior of native cellulose fibre-cotton, uses reactive dye
To dye；The latter and the dyeing behavior of animal origin-wool are approached, it is possible to it is dyed to realize with acid dyes.Dye
Three key element-temperature of color, chemical concentration, reaction (insulation) time respectively have similar, also there is difference.
First, on temperature：Viscose rayon is generally dyed with as little as medium temperature (40 DEG C~80 DEG C), and will be to nylon fibre
Dyeing needs high temperature (95 DEG C~98 DEG C) to realize.
Secondly, on chemical concentration：It is often referred to trigger the conditioned media (acid, alkalescence) of chemistry.Viscose rayon needs
The anionic of cellulose fibre while in the basic conditions active group β-ethyl sulfone sulfuric acid ester degreasing change are realized under alkalescence condition
Substitution and addition reaction occurs into active β-vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) and cellulose fibre, generates covalent bonding, there is pollutant
Fastness.And nylon fibre nylon fibre under acid or slightly acidic condition (isoelectric point) can be cationized, while exposure itself has
Some amide groups, carboxyl and dye anion occur ionic bond, hydrogen bond, Van der Waals force and are bonded, and complete dyestuff polyamide fibre is coloured.
Finally, with regard to the reaction time：Chemical reaction usually requires the regular hour, therefore often through the guarantor of a period of time
Temperature, it is allowed to react complete, essentially identical i.e. 40~50 minutes of the reaction time of both of the above.
To sum up, because the condition of both the above stock-dye is otherwise varied, so in the past below printworks generally use
Two kinds of techniques：
The first technique is two one bath two-step methods：Viscose rayon is first contaminated, opens cloth or yarn wash clean again after completing dyeing
The dye that begins nylon fibre, is illustrated below by technique diagram.Wherein Fig. 1 is the dyeing curve to viscose rayon, to viscous
The soda ash amount (15~30g/L) added during glue fiber fixation.Fig. 2 is the dyeing curve to nylon fibre.
Second of technique is one bath two stage process：Nylon fibre is first contaminated, completes to add soda ash after being cooled to 80 DEG C again after dyeing
(7~9g/L) and it is incubated to complete the dyeing to viscose rayon, is illustrated below again by process curve Fig. 3.
Both techniques have certain defect, are described as follows：
The whole dyeing course of the first technique (can be seen that by Fig. 1 and Fig. 2) is divided into two steps and twice (two baths) dye
Color realizes that technological process is very long (only dyeing time just reaches 160+130=290 minutes, disregards the drainage time), and
Charging, drainage it is frequent, very high base amount cause wash pressure it is huge, must acid adding neutralize, so sewage quantity can be caused
It is huge.Whole dyeing course needs to heat up twice in addition, is also not excluded for the possibility for needing additive color Yu returning something for repairs, therefore this technique labor
Dynamic productivity ratio is very low.
Second of technique (as seen from Figure 3) is compared has certain progress with the first dyeing curve, although
Dyeing has been also divided into two steps in a bath：First nylon fibre is dyed, while also realized by cooling
Viscose rayon is dyed with reactive dye.In (Fig. 3) process curve, reduced in soda ash amount ratio, but slightly sour character
State dyeing certainly will be soda ash to be consumed in later stage activity fixation, therefore alkali number is also that comparison is more, the post processing washing larger need of pressure
Want neutralisation treatment, sewage quantity has improvement but also not small.In terms of other dyeing time, when dye bath temperature is gone back from after dropping to 80 DEG C for 98 DEG C
Polyamide fibre coloring case is carried out to color, if necessary to additive color or repair color, dye bath temperature must rise back again 98 DEG C and repeat with
Preceding technique does a high temperature again, often also results in that (the simple stain time just reaches 245 minutes, disregards than relatively low labor productivity
Additive color is repaiied the color time).
The content of the invention
The invention provides a kind of dying operation it is simple, rapidly and efficiently, energy consumption saving, labor productivity is high, production cost

After use, in different temperatures (85 DEG C~95 DEG C) section, coordinate different soda ash dosages (1~3g/L), contaminate the tinctorial yield of product almost
Do not receive be affected (some are better on the contrary), and aberration (⊿ E≤± 0.5) in tolerance interval.
(32) 9 kinds of permutation and combination experimental results of L9 according to table two are by above-mentioned shown and required according to international standard
Soaping fastness experiment, perspiration fastness, crock fastness (reference standard ISO) have been done to 4 dyestuffs of various screening schemes respectively.
Wherein soaping fastness is pressed：1SO 105-C03-1994
Perspiration fastness is pressed：1SO 105-E04-2008
Crock fastness is pressed：1SO 105-X12-2001
Wherein CH--- changes as former state；CO--- cotton staining；PA--- polyamide fibre staining；WO--- wool staining
Red, yellow (orange, tangerine), blue depth 2%；Dark blue depth 3%；Black depth 4%
As can be seen from Table VII, the dyeing technique of invention has been used, has made dye product to a certain amount of soda ash and certain dye
There is certain tolerance in the range of color temperature, be embodied in coloured light, color depth is more stable, while it is each under the conditions of fastness refer to
Mark is also than more consistent, or even also has and improve.
To sum up, the new technology of invention is that the high temperature for the textile dyeing for being adapted to two kinds of fiber compositions of viscose glue polyamide fibre bathes a step entirely
The dyeing of method,
At least there are following features：
Firstth, dyeing of the invention has easy operability, not only when laboratory is drawn a design still in reality
During big production, full bath, single stepping are realized, it is not necessary to add any chemicals or auxiliary agent halfway；Reduce operative employee's
Labor intensity, improves production efficiency and " safety in production " is secure.
Secondth, dyeing of the invention is time saving, material-saving, saves the energy.The whole dyeing course of new dyeing of the present invention
Time be 160 minutes.
And routine is divided to two baths and two steps just to reach 160 to be respectively completed the dyeing simple stain time of two kinds of fibers of viscose glue polyamide fibre
+ 130=290 minutes；Realized actually and in two steps to two kinds of fibers of viscose glue polyamide fibre although making moderate progress present technique
Time of the dyeing simultaneously spent by whole dyeing course also to reach 245 minutes.It is so new by contrast, dyeing of the invention
Technique is quick and (is often referred to 12 hours) that a cylinder stained clot-h can be produced within certain unit interval more, improves efficiency,
Make thinner production cost.
3rd, the present invention is in wide in range dyeing temperature section --- and reproduction that on different devices equally can be stable is perfect
Color and luster is deduced.
4th, the present invention is real high temperature, low alkali dyeing (minimum to arrive 0.7g/L with low), and level-dyeing property and fastness obtain
Fully lifting --- in a wash water is at least reduced or remitted under the premise of ensuring fastness and and blowdown, lower COD value, win and subtract for enterprise
Arrange target.
Embodiment above is only the preferred embodiment of this creation, all in this wound not to limit this creation
