Description
Technical field
The invention belongs to fabrics printing and dyeing technical field, and in particular to a kind of pulp-shaped dispersed dyes and preparation method thereof are with answering
With short route, energy-saving and emission-reduction printing technology for dacron.
Background technology
In the 1930s, synthetic fibers have started new era of textile fabric, there are a variety of synthetic fibers to come out in succession,
Exploitation of the development of dyestuff always with fiber is closely connected.In fabrics printing and dyeing industry, commonly use granular dyestuff, sizing mixing or
When preparing dye liquor, dyestuff dust from flying, not only hinder environmental protection, and be often adhered on the apparatus of dispensing, or contaminated preparing
Suspended in vacuole foam, it is particularly small in solubility, the disperse dyes of dispersive property difference, easily form agglomerate, in stamp or dyeing
It is to be also easy to produce fault, influences product quality.Disperse dyes are a kind of powdery or granular nonionic dye, and molecular structure is small,
It is adapted to the dyeing of terylene and its blend fabric.But because it is free of-COOH ,-SO3The strong water-soluble group such as H, the solubility in water
It is low, it is unfavorable for absorption and upper dye of the dye molecule in fiber surface under lower temperature.
Polyester fiber is the maximum synthetic fibers of yield, and polyester fiber should greatly develop difference in addition to large traditional product
Other chemical fibre dimension, particularly superfine fibre, because the surface area of its unit mass attenuates with filament number and increase, and cause dyeing speed
Spend it is fast, apparent to color is shallow and fastness to light declines, for disperse dyes, it is necessary to solve level-dyeing property, covering property, enhancing and dyeing
Fastness problem；The printed articles of dacron accounts for 40% or so of terylene dyeing and printing process total amount；The major way of printed polyester has
Direct printing, pigment printing, thermal transfer printing.
Direct printing is the major way of current stamp, is that a kind of be prepared into commercial dyes, thickener and additive has
The print paste of certain viscosity, then carry out stamp, drying, decatize and the conventional machining techniques of multiple tracks washing；With high viscosity, low
The development of the synthetic thickening agent of solid content, can reduce the dosage of synthetic thickening agent in print paste, but because existing disperse dyes with
The compatibility of synthetic thickening agent is poor, to obtain the print paste of certain viscosity, it is still necessary to configure high solids content（Such as 5~6%）'s
Synthetic thickening agent print paste, to prevent the decline of stamp dielectric viscosity.Because of the increase of synthetic thickening agent dosage in print paste,
Cause direct printing dye utilization rate low, the massive laundering in road after PRINTED FABRIC needs, the loose colour of fabric face could be removed, come
The color fastness of terylene printing product is improved, obtains the feel of softness, therefore, the maximum inferior position of direct printing is：Due to print paste
Middle solid contents is high, it is necessary to evaporate processing to complete upper dye of the dyestuff to fiber；Printed articles loose colour is serious, Boardy Feeling, needs
Postprocessing working procedures are washed, remove the organic matter and dyestuff not shifted, it is very big to the consumption of water resource（Account for dyeing process
70%）, wastewater discharge is very big, and the colourity of waste water is deeper, and COD value is higher.Existing pigment printing is by commercial coating, synthesis paste
Material and additive（Adhesive and crosslinking agent）The print paste with certain viscosity is prepared into, then carries out stamp, drying, at high temperature
The conventional machining techniques of reason；Because adhesive and dosage of crosslinking agent are larger in pigment printing, printing quality is bad, and color fastness is poor,
The maximum inferior position of pigment printing is：The performance of adhesive and crosslinking agent determines the color fastness and feel of printed articles, relative to
For direct printing product, color fastness is poor, and feel is harder or coarse, and the chromatogram of coating is abundant and various not as good as disperse dyes
Change.The shortcomings that because of pigment printing, the application of pigment printing is limited, be only used for small area or to the less demanding stamp of feel
Product；The thermal transfer printing of existing disperse dyes is that heat resistance is poor, and the disperse dyes of easy heat sublimation, which are pre-printed on, to be turned
In paper transfer, then by transfer paper and the hot pressing function of fabric, the disperse dyes in transfer paper are allowed to be transferred to the stamp skill on fabric
Art；The maximum inferior position of thermal transfer printing is：Color fastness is poor, and depth of color is shallower, and hardly possible obtains deep printing product, and to consume
The transfer paper of equal stamp quantity, causes the wasting of resources and secondary pollution（The dyestuff remained in transfer paper）.
In existing direct printing mill base, all using commercial dispersants dyestuff, because of the phase of commercial dispersants dyestuff and synthetic thickening agent
Capacitive is poor, substantially reduces the viscosity of thickener, causes the rheological property of print paste poor；Therefore, it is necessary to develop it is a kind of with
The preferable liquid dispersion dyestuff of synthetic thickening agent compatibility, can just prevent dyestuff from settling, and improve print paste viscosity.And use city
The disperse dyes sold, either powder solid or liquid dispersion dyestuff, it is required for increasing thickener dosage, when could meet stamp
Requirement to stamp slurry viscosity.
With today that energy-saving, energy-saving and emission-reduction requirements are increasingly taken seriously, the new terylene of necessary research and development
Textile printing technology is, it is necessary to both have the advantages of stamp work flow is short, small to water resources consumption amount of wastewater discharge is small, again
With stamp color fastness is excellent and the advantages of fabrics feel soft；Need to avoid simultaneously direct printing to water resources consumption amount greatly and
The shortcomings that wastewater discharge is big, the shortcomings that also avoiding pigment printing feel harder or coarse, color fastness is poor.
