The Advantages of jinji Brand Reac-tive
Dyestuffs
---Large technological tolerance, little dependence
on dyeing technological conditions and good
stability of dyeing;
---With high strength, purity and solubility, adapting
to dyeing in different bath ratios;
---With good migration property, levelness, permeability,
dispersion, and ability to cover up the
flaws for fabric;
---Higher build up and deep dyeing;
---Excell compatibility, good reproduction, excellent
fastness, being adapted to different dyeing
conditions and equipment so as to reach top quality of
dyeing;
---Suitable for dip dyeing, continuous dyeing, cold pad-ding
batch and printing. |

（一）The pad dyeing process with pad-baking and pad-steaming method
.
1、Flow process
.
Pad dyeing-----Prebaking-----Drying-----Liguor padding-----Steaming-----Deterout washing-----Soaping-----Water washing------Drying
.
2、Conditions：
.
Exhaust and pad dyeing liguid：Temperature 20℃ -30℃
Prebaking：lifrared,transversing hot wind,from low to high temperature
Drying： Hot wind or rotary drum drying
Exhaust and pad dyeing liguid： 轧余率≤100％
steaming temperature： 102℃ -104℃
steaming time： 40-90seconds
Detergent washing： Wash the cloth surface to neutral
Boiling with soap： Boiling with soap with the temperature95℃
water washing： wash off the floating color
Drying： uniform baking and drying
.
3、Components of dyeing liguid：
.
Dye xg/L
Anti-migration agent1-2g/L
Penetrant0-0.2g/L
.
4、Components of alkali mixture：
.
NaOH 38°Be′ 12-15ml/L
Na2CO3 20-40g/L
salt or anhydrous sodium sulfate 150-200g/L
Reserving salt-S 10 g/L
.
(二)The pad dyeing process with baking and onephase method:
.
(The process is only applicable for light or medium color dyeing, which is not recommended in a genral way.)
.
1、How process：
.
pad dyeing-----pre-baking-----drying------baking------detergent washing-----soaping------water washing------drying
.
2、Conditions：
Exhaust and pad dyeing liquid： Temperature 20-30℃,Pickup≤70％
Prebaking： infraed,transversing hot wind,warming gradually
Drying： hot wind or rotary drum drying, progressive drying
Baking temperature： 140℃-160℃
Backing time： 60-120 seconds
Detergent washing： Washing the cloth surface to neutral
Soaping： Boiling with soap above 95℃
Drying： Uniform Baking and drying
.
3、Components of dyeing liquid
Dye：Xg/L
Urea：0-100g/L
Baking soda：10-30g/L
Reserving salt-S： 0-10g/L
Anti-migration agent：1-2g/L
Penetrant：0-0.2g/L
Note:Bake and boil the textile with soap once the exhaust and pad dyeing liquid get dried.
.
Remark：
1、 It is required to pretreat the halffinished product well,keep the cloth surface clean and neutral；
2、 It is needed to use soft water or ion exchanging water to prepare the dyeing liquid and alkali liquor；
3、 It is required to choose the anti-migration agent that won't solidify or film；
4、 It is better to prebake gradually,from low to high temperature；
5、 It is required to wash such residues as salt,alkali off the cloth surface before soaping；
6、 It is required to use anionic or nonionic detergent to toil with soap；
