Description
Technical field
The invention belongs to textile technology field, is related to a kind of colouring method without desizing.
Background technology
In the weaving process of woven fabric, starching is one of important process.Starching is exactly to allow warp thread to turn into slurry
Yarn, apply slurry on warp thread to improve the technical process of its weavability.Starching is played a part of including improving warp to sizing
The wearability of yarn, improve the collection of filaments, improve yarn breakage intensity so that warp thread has good elasticity, flexibility and broken
Extensibility is split, Yarn filoplume patch volt, surface are smooth, and with suitable humidity etc..
But during follow-up dyeing arranges, because slurry can influence the dyeability of its fabric, so carrying out
, it is necessary to carry out desizing to woven fabric before dyeing, it is ensured that follow-up dyeing is not had an impact.If non-desizing, dyestuff are difficult to
Penetrate slurry and complete to dye with warp thread.Specific fabric production in, to fabric carry out desizing dyeing after, need to again through starching with
The shape of fabric is kept, in order to follow-up cutting.If can complete to dye without desizing, production process can be reduced, is reduced
Energy consumption, pollution is reduced, save cost.
The content of the invention
It is an object of the invention to provide a kind of colouring method without desizing, and the beneficial effects of the invention are as follows without to shuttle
Fabric, which carries out desizing, can complete to dye, and reduce dyeing process, reduce pollution, save cost.
The technical solution adopted in the present invention is to follow the steps below：
Step 1：NaOH solution is prepared, NaOH solution is added in liquefied ammonia, it is molten to be made into the liquid ammonia-water mixing containing NaOH
Liquid；
Step 2：Reactive dye are added into liquefied ammonia-water mixed solution containing NaOH, the liquid ammonia-water containing NaOH is made into and mixes
Close dye liquor；
Step 3：The non-desizing woven fabric of cellulose fibre is immersed in the liquid ammonia-water mixing dye liquor containing NaOH and carried out
Dyeing, takes out after dyeing, and drying removes ammonia fixation, completes the process of no desizing dyeing.
Further, the concentration of NaOH solution is 240g/L in step 1；NaOH solution and the volume ratio of liquefied ammonia are 8：92.
Further, dyeing time is 10 minutes in step 4.
Further, dyeing temperature is -34 DEG C in step 4.
Further, cellulose fibre is ramie woven in step 4.
Embodiment
With reference to embodiment, the present invention is described in detail.
Embodiment 1：The NaOH of 18,20,22,24 and 26g is dissolved in 100ml water respectively, is made into 180,200,
220,240 and 260g/L NaOH solution.Take 8ml is above-mentioned to be configured to different NaOH solutions and be slowly added into 92ml liquefied ammonia,
It is made into liquefied ammonia-water mixed solution containing different NaOH contents.Again by 0.2g Reactive Red 2, REACTIVE Red 195, and reactive orange 5
Reactive dye are added separately in liquefied ammonia-water mixed solution that 100ml contains different NaOH contents, are made into and are contained containing different NaOH
The liquid ammonia-water mixing dye liquor of amount.By the ramie woven of the non-desizing of 4g be immersed in it is above-mentioned prepare containing different NaOH contents
In liquid ammonia-water mixing dye liquor, dyeing 10 minutes is carried out at its own temperature (about -34 DEG C), then takes out, dries except ammonia is consolidated
Color, complete no desizing dyeing.
In order to examine the Color of no desizing, the ramie woven after dyeing is subjected to desizing, soaps, detects its K/S
Value, is listed in Table 1 below.Table 1 shows the increase with NaOH content, the K/S values of the non-desizing ramie cloth of three kinds of dyeing dyeing
Also gradually increase, and reach maximum in 240g/L.Therefore, to non-desizing ramie under conditions of NaOH content is 240g/L
The Color of cloth is optimal.
Influence of the 1. different NaOH contents of table to non-desizing ramie tatting cloth dyeing K/S values
| NaOH content (g/L) | Reactive Red 2 | REACTIVE Red 195 | Reactive orange 5 |
| 180 | 6.22 | 7.36 | 10.82 |
| 200 | 6.67 | 7.52 | 11.28 |
| 220 | 7.08 | 8.09 | 11.89 |
| 240 | 7.65 | 8.42 | 12.37 |
| 260 | 7.53 | 8.28 | 12.21 |
Embodiment 2：24g NaOH is dissolved in 100ml water, is made into 240g/L NaOH solution.Take 8ml is above-mentioned to match somebody with somebody
Manufactured NaOH solution is slowly added into 92ml liquefied ammonia, is made into liquefied ammonia-water mixed solution containing NaOH content.Again will
The reactive dye of 0.2g Reactive Red 2, REACTIVE Red 195, and reactive orange 5 are added separately to 100ml and contain different NaOH contents
In liquefied ammonia-water mixed solution, the liquid ammonia-water mixing dye liquor containing NaOH content is made into.The ramie woven of the non-desizing of 4g is soaked
Enter into the above-mentioned mixing dye liquor of the liquid ammonia-water containing NaOH content prepared, dyed at its own temperature (about -34 DEG C)
4,6,8,10 and 15 minutes, then take out, drying removes ammonia fixation, completes no desizing dyeing.
In order to examine the Color of no desizing, the ramie woven after dyeing is subjected to desizing, soaps, detects its K/S
Value, is listed in Table 2 below.Table 2 shows the extension with dyeing time, the K/S values of the non-desizing ramie cloth of three kinds of dyeings also by
It is cumulative to add, and reached maximum at 10 minutes.Therefore, to non-desizing ramie cloth under conditions of dyeing time is 10 minutes
Color is optimal.
Influence of the coloured differently time of table 2. to non-desizing ramie tatting cloth dyeing K/S values
| Time (minute) | Reactive Red 2 | REACTIVE Red 195 | Reactive orange 5 |
| 4 | 6.22 | 7.36 | 11.04 |
| 6 | 6.67 | 7.52 | 11.78 |

Embodiment 3：24g NaOH is dissolved in 100ml water, is made into 240g/L NaOH solution.Take 8ml is above-mentioned to match somebody with somebody
Manufactured NaOH solution is slowly added into 92ml liquefied ammonia, is made into liquefied ammonia-water mixed solution containing NaOH content.Again will
The reactive dye of 0.2g Reactive Red 2, REACTIVE Red 195, and reactive orange 5 are added separately to 100ml and contain different NaOH contents
In liquefied ammonia-water mixed solution, the liquid ammonia-water mixing dye liquor containing NaOH content is made into.The ramie woven of the non-desizing of 4g is soaked
Enter into the above-mentioned mixing dye liquor of the liquid ammonia-water containing NaOH content prepared, in its own temperature (about -34 DEG C), -40 DEG C, -50
DEG C, and dyeing 10 minutes is carried out at -60 DEG C, then take out, drying removes ammonia fixation, completes no desizing dyeing.
In order to examine the Color of no desizing, the ramie woven after dyeing is subjected to desizing, soaps, detects its K/S
Value, is listed in Table 3 below.Table 3 shows the reduction with tinction temperature, and the K/S values of the non-desizing ramie cloth of three kinds of dyeings are substantially not
Change, it is little to show that dyeing temperature influences on the Color of non-desizing ramie woven fabric, but reducing dyeing temperature needs increase outer
Portion's energy, therefore the condition dyed under this own temperature is optimal.
Influence of the coloured differently temperature of table 3. to non-desizing ramie tatting cloth dyeing K/S values
