Description
Technical field
The invention belongs to textile technology field, is related to a kind of method for improving dye exhausting rate in liquid ammonia medium dyeing.
Background technology
Liquefied ammonia has the function that to expand and reduce crystallinity to cellulose fibre, is usually used in textile industry to cellulose
Fiber carries out mercerized finish.Meanwhile liquefied ammonia has certain dissolving to water miscible dyestuff, such as reactive dye and direct dyes
Performance, therefore, aqueous medium can be replaced using liquefied ammonia, cellulose fibre is dyed.
In liquefied ammonia dyeing course, dyestuff is initially dissolved in liquid ammonia medium, and liquefied ammonia dye liquor is made.When cellulose fibre soaks
Enter into liquefied ammonia dye liquor, liquefied ammonia dye liquor enters fibrous inside within the extremely short time, and solution crystallization, increased fiber are carried out to fiber
Amorphous region, while complete attachment of the dyestuff on fiber.In subsequent drying removes ammonia fixation, dyestuff and fiber-reactive,
Complete dyeing course of the fiber in liquid ammonia medium.However, because the polarity of liquid ammonia medium is not high, dyestuff is in liquid ammonia medium
Dissolubility is relatively low, therefore, cellulose fibre liquefied ammonia dyeing in, there is dye exhausting rate it is not high the shortcomings that.
The content of the invention
It is an object of the invention to provide a kind of method for improving dye exhausting rate in liquid ammonia medium dyeing, solve in liquefied ammonia
The problem of dye exhausting rate is poor in medium dyeing.
The technical solution adopted in the present invention is to follow the steps below：
Step 1：A small amount of water is added in vial, then adds liquefied ammonia, and stir and be made into liquid ammonia-water blend solution；
Step 2：Reactive dye are added in liquid ammonia-water blend solution, complete the liquid ammonia-water dye liquor of different moisture content
Prepare；
Step 3：Cellulose fibre is put into liquid ammonia-water dye liquor and dyed.
Further, in step 1, in liquid ammonia-water blend solution, the volume ratio of liquefied ammonia and water is 92：8.
Further, dyeing time is 10 minutes in step 3.
Further, dyeing temperature is -34 DEG C in step 3.
Further, cellulose fibre is ramie staple in bulk.
The amount of dye that dyestuff is attracted on fiber is improved the beneficial effects of the invention are as follows effect, improves the utilization of dyestuff
Rate.
Embodiment
With reference to embodiment, the present invention is described in detail.
Embodiment 1：0,2,4,6,8 and 10ml water are added in vial, liquefied ammonia is added while stirring to 100ml, matches somebody with somebody
Into the liquid ammonia-water blend solution that water content is 0%, 2%, 4%, 6%, 8% and 10% (volume fraction), then by 0.06g's
Reactive Red 2, reactive orange 5, the reactive dye of REACTIVE Red 195 are added separately to the liquid ammonia-water blend solution of above-mentioned different moisture content
In, complete the preparation of the liquid ammonia-water dye liquor of different moisture content.
2g ramie staple in bulk is immersed in above-mentioned matched somebody with somebody liquid ammonia-water dye liquor, stirring dyeing 10 minutes at -34 DEG C
Afterwards, ramie loose stock dyeing thing is taken out.By content of the dyestuff in dye liquor before and after spectrophotometer detection dyeing, and calculate
The exhaustion rate of dyestuff during it is dyed, the results are shown in Table 1.Table 1 shows that aqueous medium is added in liquefied ammonia can effectively improve dyestuff
Exhaustion rate, and as the increase of water content in liquid ammonia-water dye liquor, the exhaustion rate of dyestuff gradually step up, and in 8% water content
Reach maximum, when being further added by 10%, the exhaustion rate of dyestuff somewhat declines.Therefore, the water content that 8% is added in liquefied ammonia can
So that dye exhausting rate of the ramie staple in bulk in the dyeing of liquid ammonia-water dye liquor reaches optimal.
Influence of the different moisture content of table 1. to dye exhausting rate
Embodiment 2：8ml water is added in vial, liquefied ammonia is added while stirring to 100ml, is made into water content 8%
The liquid ammonia-water blend solution of (volume fraction), then by 0.06g Reactive Red 2, reactive orange 5, the reactive dye of REACTIVE Red 195
It is added separately in above-mentioned liquid ammonia-water blend solution, completes the preparation of liquid ammonia-water dye liquor.
2g ramie staple in bulk is immersed in above-mentioned matched somebody with somebody liquid ammonia-water dye liquor, the stirring dyeing 1,3,5 at -34 DEG C,
After 7,10 and 15 minutes, ramie loose stock dyeing thing is taken out.By dyestuff before and after spectrophotometer detection dyeing in dye liquor
Content, and the exhaustion rate of dyestuff in its dyeing is calculated, the results are shown in Table 2.Table 2 shows, with the increase of dyeing time, dye
The exhaustion rate of material is gradually stepped up, and constantly reaches maximum at 10 minutes, then extends to 15 minutes, and the exhaustion rate of dyestuff is kept not
Become.Therefore, the dyeing time of 10 minutes may be such that dye exhausting rate of the ramie staple in bulk in the dyeing of liquid ammonia-water dye liquor reaches most
It is good.
Influence of the coloured differently time of table 2. to dye exhausting rate
Embodiment 3：8ml water is added in vial, liquefied ammonia is added while stirring to 100ml, is made into water content 8%
The liquid ammonia-water blend solution of (volume fraction), then by 0.06g Reactive Red 2, reactive orange 5, the reactive dye of REACTIVE Red 195
It is added separately in above-mentioned liquid ammonia-water blend solution, completes the preparation of liquid ammonia-water dye liquor.
2g ramie staple in bulk is immersed in above-mentioned matched somebody with somebody liquid ammonia-water dye liquor, in -34 DEG C, -40 DEG C, -50 DEG C and -
After stirring is dyed 10 minutes at 60 DEG C, ramie loose stock dyeing thing is taken out.Existed by dyestuff before and after spectrophotometer detection dyeing
Content in dye liquor, and the exhaustion rate of dyestuff in its dyeing is calculated, the results are shown in Table 3.Table 3 shows, with dyeing temperature
Reduction, the exhaustion rate of dyestuff keeps constant.But -34 DEG C of temperature for liquefied ammonia itself, without external refrigeration, i.e. no consumption energy
Amount.Reducing the temperature at -34 DEG C then needs to consume external energy.Therefore, -34 DEG C of dyeing temperatures be ramie staple in bulk liquefied ammonia -
The optimum temperature of water dye liquor dyeing.
Influence of the coloured differently temperature of table 3. to dye exhausting rate
It is also an advantage of the present invention that：Aqueous medium has preferable polarity, dissolves more dyestuff.Meanwhile although liquefied ammonia
The temperature of itself is -34 DEG C, but when a small amount of aqueous medium is added in liquefied ammonia, and under conditions of stirring, aqueous medium is in liquefied ammonia
In can't freeze, can with liquefied ammonia formed blend solution.In addition, liquid ammonia-water blend solution is maintaining expansion of the liquefied ammonia to fiber
Outside the effect for conciliating crystallization, solubility of the dyestuff in liquefied ammonia can be improved, so as to improve exhaustion rate of the dyestuff in liquefied ammonia dyeing.
Described above is only the better embodiment to the present invention, not makees any formal limit to the present invention
System, any simple modification that every technical spirit according to the present invention is made to embodiment of above, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
