Comparative example 1-5
A certain amount of salt is dissolved in 15ml water and obtains salting liquid.Then 1gm baftas are soaked
Enter into salting liquid, and by container water-bath 10 minutes.Temperature is 50 DEG C, and vibration frequency is 110
Beat/min.Table 2 lists the mass percent of dyestuff in comparative example 1-5 in contrast to 1 gram of fabric,
The corresponding concentration of salt solution of difference.It is based on table 2 that the Levafix Red CA dyestuffs of respective amount is molten
In the salting liquid.And container is placed to the dyeing processing carried out in water bath 1 hour.Temperature
Spend for 50 DEG C, vibration frequency is 110 beats/min.After dyeing, add in a reservoir a certain amount of
Aqueous sodium carbonate (1ml), using with dyeing course identical condition vibrate 1 hour carry out
Fixation treatment.Concentration is such as the corresponding color fixing agent of dyestuff (i.e. sodium carbonate) of different quality percentage
Table 2.After fixation, cotton is immersed in 25ml washing powder solution (2g/L), juxtaposition
Enter in water-bath and to be vibrated 15 minutes with 110 beats/min of frequency.Laundry is taken into washed cotton
Rinsed and dried with water.
Table 2：The comparative example 1-5 corresponding salting liquid of dyestuff mass percent and fixation agent concentration
Comparative example 6-10：
Comparative example 6-10 is corresponding with comparative example 1-5, and it is differed only in Levafix Red
CA reactive dye are substituted for Levafix Blue CA reactive dye.
Comparative example 11-15：
Comparative example 11-15 is corresponding with comparative example 1-5, and it is differed only in Levafix Red
CA reactive dye are substituted for Levafix Yellow CA reactive dye.
The bafta dyed by non-aqueous dyeing process methods prepared by embodiment 1-15 as
Test sample, and the bafta that comparative example 1-15 is dyed by the use of aqueous dyeing process methods as
Reference substance.The K/S values measurement result difference of the test sample and reference substance is as shown in Figures 2 and 3.
The Color of test sample and reference substance can be compared by K/S values.K/S values refer to dye
The intensity of colour size of yarn dyed fabric, is calculated by Kubelka-Munk formula：
K/S=(1-R)2/ 2R, wherein R are the reflectance factor of fabric, by spectrophotometer SF650
(DataColor International, USA) is determined, and wave-length coverage is 400nm-700nm,
It is divided into 10nm.K/S value is bigger, and bafta coloring is better.
It can be seen that and used by single bath process in organic solvent (non-aqueous by Fig. 2 and Fig. 3 results
Agent) in the reverse micelle Feng Installed reactive dye absorption Color that is formed be slightly below the dye of the aqueous solution
Color effect.
The present invention utilizes the reactive dye technology of single bath process and nonionic surfactant Feng Installed
It is combined, compared with the reverse micelle technology utilized in the prior art, is avoiding using excessive water
Can effectively it be dyed simultaneously, the stainability to bafta is stronger.And single bath process is continuous
The technique of processing also saves raw material while effectively dyeing and fixation is ensured.In addition, this
The dyeing of invention does not need special process conditions for the angle of energy-conservation, to cotton
Stainability is also without very high requirement.Non-aqueous dyeing course can be in lower temperature range
(50 DEG C -70 DEG C) realizations, are encapsulated in reactive dye in reverse micelle not cotton made from facile hydrolysis
Cloth will not also lose colour developing and the tinting strength, tinting power of dyestuff in cleaning process, so as to keep good
Dyeing quality.The dyeing course of the present invention does not need electrolyte, eliminates electrolyte to environment
Pollution.The dyeing of organic solvent is also very environmentally friendly, and water is used because greatly reducing
Amount and colorful wastewater treating capacity, and can also effectively reclaim organic solvent.
It should be appreciated that for those of ordinary skills, can be according to the above description
Improved or converted, all these improvement or conversion should all belong to appended claims of the present invention
Protection domain within.
