Abstract
The invention belongs to the technical field of textile dyeing and printing, and provides a method for carrying out cationic modification upon cotton fabric by using paint dyeing wastewater. The method comprises the steps that: conventional paint dyeing wastewater is filtered by using a microporous filtering membrane with a pore size of 0.22 micrometers; a 1-2g/L cationic modifying agent is added into the obtained filtrate, and secondary filtering is carried out by using a microporous filtering membrane with a pore size of 0.1 micrometers; a 7-10g/L cationic modifying agent is added into the obtained filtrate, such that a cationic modifying solution is prepared; the solution is regulated to an appropriate condition; and the cotton fabric is added and is subjected to a cationic modifying treatment. With the method provided by the invention, paint particles in anionic paint dyeing wastewater can be removed, and the residual liquid is adopted as a medium for carrying out a cationic modification processing upon the cotton fabric. Therefore, dyeing wastewater recycling is realized.
Description
Technical field
The present invention relates to a kind of pigment dyeing waste water that utilizes COTTON FABRIC is carried out to cation-modified method, belong to technical field of textile printing.
Background technology
For a long time, cotton fabric dyeing process mainly utilizes activity and reducing dye to realize.Along with the development of the deep and coating process technology of colourist to coating property understanding, coating is also widely used in the dyeing of COTTON FABRIC.Pigment dyeing method has technique simple and stable, saves the energy, shortens the advantages such as flow process.In addition, it also has unique style, as obvious washing sensation and well-bedded third dimension etc.
What in exhaust dyeing with pigment technique, generally use is anion coating, and anion coating, needs employing first COTTON FABRIC to be carried out cation-modified, then carries out pigment dyeing without affinity cotton fiber, and the mode of finally carrying out fixation treatment completes pigment dyeing technique.Because cation modifier, anion coating and fixation are larger with the nature difference of adhesive, for ensureing best Color, above-mentioned three processes are carried out conventionally in different processing is bathed, machine rear respectively by residual liquid discharge, thereby cause the waste of water resource.
Cation modifier and fixation are all water soluble molecules with adhesive, in water, exist with molecule or colloidal state, are difficult to separate from solution, and therefore cation-modified and fixation treatment liquid cannot effectively be reused.Anion coating particles is water insoluble, and grain size, 1 micron of left and right, is suspended in dyeing liquor with dispersity, can effectively remove by physics or chemical method, so can utilize its raffinate to carry out the processing of other operation.
Summary of the invention
The object of this invention is to provide a kind of pigment dyeing waste water that utilizes COTTON FABRIC is carried out to cation-modified method, can efficiently remove the coating particles in anion pigment dyeing waste liquid, then utilize this raffinate, as medium, COTTON FABRIC is carried out to cation-modified processing, realize the recycling of dyeing waste-water.
The present invention includes following technique:
(1) conventional anion pigment dyeing waste water is filtered with the miillpore filter that aperture is 0.22 micron;
(2) in filtrate, add 1-2g/L cation modifier, at 30 DEG C, stir 10-15min, then filter with the miillpore filter that aperture is 0.1 micron;
(3) in filtrate, add 7-10g/L cation modifier to be mixed with cation-modified treatment fluid, be warming up to 85-90 DEG C, with NaOH adjusting pH to 9.5-10, add COTTON FABRIC, controlling bath raio is 1: 10, processes 20-30min; After cation-modified finishing dealing with, fabric is fully washed and in 100 DEG C of oven dry.
Pigment dyeing waste water is filtered, and object is to remove the coating particles suspending, and can adopt the miillpore filter of the device assembling certain pore size such as conventional sand core funnel to carry out.Filter membrane can adopt commercially available nylon 6 or polytetrafluoroethylene (PTFE) miillpore filter.The aperture of filtration employing is for the first time the miillpore filter of 0.22 micron, can effectively remove most of coating particles, and remaining less coating particles need could remove completely through further processing.In filtrate, add 1-2g/L cation modifier, can be combined with electronegative anion coating generation opposite charges, anion coating surface current potential is reduced, coating particle occurs obviously to reunite, it is large that size becomes, by being can all remove from raffinate after the filtering with microporous membrane of 0.1 micron with aperture for the second time.Cation modifier used is commercially available COTTON FABRIC pigment dyeing quaternaries cation modifier, and excessive cation modifier can continue to play a role in following process, without any adverse effect.After twice filtration treatment, residual without any coating in filtrate, can be used as the medium of the cation-modified processing of COTTON FABRIC.In filtrate, supplement and add 7-10g/L cation modifier, temperature is risen to 85-90 DEG C, with NaOH adjusting pH to 9.5-10, add COTTON FABRIC, controlling bath raio is 1: 10, processes 20-30min, completes the cation-modified processing to COTTON FABRIC.Finally, fabric is fully washed and in 100 DEG C of oven dry.
The invention provides a kind of pigment dyeing waste water that utilizes COTTON FABRIC is carried out to cation-modified method, the method is utilized cation modifier reunion anion coating, mode in conjunction with secondary filter is removed the coating particle in pigment dyeing waste liquid completely, then utilize this filtrate, as medium, COTTON FABRIC is carried out to cation-modified processing, realize the recycling of dyeing waste-water.
