(owf), thiourea dioxide 1-20g/L, pH buffer agent 1-3g/L, penetrating agent 1-3g/L, accelerator 5-30g/L；
S2, alkali immerging, directly pad alkali liquor by the dyeing and weaving thing for the treatment of obtained through S1 process, an immersing and rolling,
The temperature padding groove is 55-75 DEG C, and pick-up is 40-80%, and described alkali liquor includes: Caustic soda 5-30g/L, guarantor
Danger powder 0-10g/L；
S3, reduction decatize, use saturated vapor to carry out quick decatize, and the temperature of reduction decatize is 100-110 DEG C,
Steaming time is 0.5-1.5min；
S4, oxidation, use hydrogen peroxide to aoxidize, and oxidizing temperature is 30-50 DEG C, and oxidization time is 5-20min.
Preferably, in S1, the preparation method of described reducing dye microcapsules includes: ground by reducing dye
The configuration that adds water after mill obtains the suspension of reducing dye, in the reducing dye suspension that concentration is 30-45g/L
Adding concentration is the chitosan solution of 25-35g/L, contains the glacial acetic acid of 3-5wt% in described chitosan solution,
Stirring to being uniformly dispersed, add the gelatin solution that concentration is 65-75g/L, same stirring to being uniformly dispersed,
Continuously adding and be warming up to 60-80 DEG C under liquid paraffin and surfactant Span-80, stirring condition, insulation is stirred
After mixing 10-20min, it is cooled to 3-6 DEG C, is subsequently added into the glutaraldehyde solution that concentration is 35-40wt%, solidification
Reaction 1.5-2.5h, after being centrifuged, acetone rinse is also dried, and obtains described reducing dye microcapsules；Preferably
Ground, described reducing dye suspension, chitosan solution, gelatin solution, the volume ratio of glutaraldehyde solution are
1:0.5-1:2-3:0.05-0.1。
Preferably, in S1, described accelerator be the sodium sulfate by weight ratio 1:3-5 and sodium chloride compounding and
Become.
Preferably, in S1, bath raio is 1:10-30, and the temperature padding groove is 35-45 DEG C, and pick-up is
80-90%.
Preferably, in S2, the temperature padding groove is 60-70 DEG C, and pick-up is 50-70%.
Preferably, in S3, the temperature of reduction decatize is 103-108 DEG C, and steaming time is 0.8-1.2min.
Preferably, in S4, the hydrogen peroxide using concentration to be 25-35wt% aoxidizes, the consumption of hydrogen peroxide
For 0.5-5g/L, oxidizing temperature is 35-45 DEG C, and oxidization time is 10-15min.
Preferably, after S4, also include technique of soaping, it is preferable that it uses soaping agent to soap,
Soaping agent is dodecylbenzene sodium sulfonate and the compounding formation of NP-100 of weight ratio 1:0.4-0.8, soaping agent
Consumption is 1-3g/L, and temperature of soaping is 80-100 DEG C, and the time of soaping is 5-25min.
Proposing a kind of reducing dye suspended substance wet short steaming and rolling dyeing dyeing in the present invention, it is initially with going back
Former dyestuff and reducing agent are with bathing material, owing to will treat that dyeing and weaving thing directly pads the reducing dye liquid containing reducing agent
In, and without drying direct alkali immerging (containing a small amount of reducing solution), then decatize, oxidation, i.e. complete and knit
The reduction stain process of thing, the most whole pad dyeing process is not dried through bottoming, is the most significantly subtracted
Lack the defects such as the aberration that causes is dried in bottoming, migration cloth cover grows dim, and simple to operate, it is possible to reduce
Energy resource consumption.Meanwhile, dry the hygrometric state dyestuff that caused and come off more lacking in order to avoid saving bottoming
Fall into, the present invention uses complex coacervation prepare a kind of reducing dye microcapsules, described microcapsules
Formed and have benefited from the cationic of chitosan and the both sexes feature of gelatin, and in the condition of glutaraldehyde as cross linker
Under, by inverse suspension crosslinking method, prepare a kind of chitosan/gelatin-compounded carrier material (wall material), compound
The core-shell structure copolymer reducing dye microcapsules of reducing dye (nucleome), this reducing dye microcapsules has excellent
Slow-release function, thus while dyeing speed is controlled, have more the stability improving dye suspensions
Can, thus strengthen the effect of level dyeing, coloring and dyestuff penetration；Simultaneously in order to increase reduction in the present invention
The reproducibility of agent, contaminates together with dyestuff also by by reducing agent, to ensure that reducing solution realization can be by all
Even absorption, therefore when described fabric carries out reducing decatize at relatively high temperatures, can significantly improve fabric
Color so that whole cloth cover even dyeing, repeatability and color fastness all can be obviously improved, finally,
Good finished product effect is obtained after fabric is aoxidized.

The method of testing of the indices in the present invention is as follows:
(1) before and after using Hunter3Lab colour photometer cotton polyester fabric lower to dyeing, aberration △ E detects；
(2) color fastness
Fastness to soaping is according to GB/T 3921-2008 " textile color stability test fastness to soaping "
Method D (4) measures.
Colour fastness to perspiration measures according to GB/T 3922-1995 " textile colour fastness to perspiration test method ".
Colour fastness to rubbing is surveyed according to GB/T 3920-2008 " fabric color fastness test colour fastness to rubbing "
Fixed.
The color fastness of resistance to artificial light is according to GB/T 8426-1998 " fabric color fastness test color fastness to light: day
Light " xenon lamp method 2 measures.
The dyeability test result of the dyed fabric that above-described embodiment 1-4 obtains is as shown in the table:
Proposing a kind of reducing dye suspended substance wet short steaming and rolling dyeing dyeing in the present invention, it is initially with going back
Former dyestuff and reducing agent are with bathing material, owing to will treat that dyeing and weaving thing directly pads the reducing dye liquid containing reducing agent
In, and without drying direct alkali immerging (containing a small amount of reducing solution), then decatize, oxidation, i.e. complete and knit
The reduction stain process of thing, the most whole pad dyeing process is not dried through bottoming, is the most significantly subtracted
Lack the defects such as the aberration that causes is dried in bottoming, migration cloth cover grows dim, and simple to operate, it is possible to reduce
Energy resource consumption.Meanwhile, dry the hygrometric state dyestuff that caused and come off more lacking in order to avoid saving bottoming
Fall into, the present invention uses complex coacervation prepare a kind of reducing dye microcapsules, described microcapsules
Formed and have benefited from the cationic of chitosan and the both sexes feature of gelatin, and in the condition of glutaraldehyde as cross linker
Under, by inverse suspension crosslinking method, prepare a kind of chitosan/gelatin-compounded carrier material (wall material), compound
The core-shell structure copolymer reducing dye microcapsules of reducing dye (nucleome), this reducing dye microcapsules has excellent
Slow-release function, thus while dyeing speed is controlled, have more the stability improving dye suspensions
Can, thus strengthen the effect of level dyeing, coloring and dyestuff penetration；Simultaneously in order to increase reduction in the present invention
The reproducibility of agent, contaminates together with dyestuff also by by reducing agent, to ensure that reducing solution realization can be by all
Even absorption, therefore when described fabric carries out reducing decatize at relatively high temperatures, can significantly improve fabric
Color so that whole cloth cover even dyeing, repeatability and color fastness all can be obviously improved, finally,
Good finished product effect is obtained after fabric is aoxidized.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
Being limited to this, any those familiar with the art is in the technical scope that the invention discloses, according to this
The technical scheme of invention and inventive concept thereof in addition equivalent or change, all should contain the protection in the present invention
Within the scope of.
