Description
Technical field
The invention belongs to dyeing and finishing technique field, be specifically related to a kind of DISPERSE DYES pad-dry-cure dyeing method that dacron is medium with decamethylcyclopentaandoxane (D5).
Background technology
In the dyeing of terylene, the general DISPERSE DYES that adopts dyes, and because terylene molecular structure is tight, belong to hydrophobic fibre, in normal dyeing, is medium, needs to add the auxiliary agents such as dispersant with water.Therefore, in whole dyeing course, produce a large amount of dyeing waste-waters, not only consume a large amount of water resources, and very large pollution is caused to ecological environment.According to statistics, in China, the blowdown flow rate of textile industry comes the 4th, wherein dyeing waste water accounts for 80%, annual waste discharge 700,000,000 more than t, meanwhile, a large amount of sewage discharges causes serious chroma pollution and serious COD, BOD loading, COD and BOD of the aqueous solution of the commodity DISPERSE DYES of 1% concentration reaches 6000-13000mg/L, 100-1000mg/L respectively.Moreover, in the terylene pad-dry-cure dyeing of routine, dye sublimation causes the problems such as utilization rate is low, contamination equipment, contaminated air, and fabric feeling is poor, equipment is not suitable with small lot multi-item production etc.
Therefore, cleaning dye is very necessary, and so-called cleaning dye solves problem of environmental pollution exactly in dyeing process, and as pollution-free dyeing, anhydrous or waste water easily processes dyeing etc.Non-aqueous dyeing is the dyeing course selecting non-water dyeing medium, and the method dyeed at the non-water that dacron dyeing fermentation is conventional at present has: organic solvent dyes, vacuum sublimation dyeing and supercritical CO 2 dyeing etc.
But these non-water colouring methods all have some limitations in application process.As (1) vacuum sublimation dyeing, its general principle utilizes dyestuff under the condition of vacuum and heating, distillation occur and gasify, and stained with fiber in the mode of gas phase diffusion transfer.But this colouring method has, and dye species is few, rate of sublimation is difficult to control, seriously polluted, the problem such as equipment requirement is high of equipment.(2) selection of organic dye solvent from chloro-alkenes at first (as perchloroethylene, trichloro-ethylene etc.) fluorohydrocarbon (as C5H2F10) till now, but due to solvent dyeing exist dye-uptake low, reclaim difficulty, costly, toxic, more high series of problems is required to fire prevention, dyestuff, this type of research stops at this, fails to obtain breakthrough.(3) namely supercritical CO 2 dyeing is the dyeing of dyeing medium with supercritical carbon dioxide, has that technique is simple, flow process is short, need not clean after used additives, dyeing, dye utilization rate is high, stop the advantages such as the generation of waste water from source.But supercritical fluid dyeing needs to carry out at very high pressures, equipment investment is high, security and poor continuity, and dyeing is difficult to control, in practical application is promoted, have great limitation.In addition, because supercritical CO 2 can not dissolve hydrophilic dyestuff, this technology is difficult to the dyeing being applied to natural fabric, also limit the application and development of this technology.
So the limitation of the variety of problems existed based on dacron conventional water-bath dyeing and some current non-water colouring method application, prevent and remedy pollution from source, developing green dyeing and finishing process technology, seeks few water or non-aqueous dyeing technology seems particularly important.
Summary of the invention
Need a large amount of dispersant and other auxiliary agents for the dyeing course existed in the disperse dyeing of dacron traditional water bath, water consumption is many, sewage discharge is serious, the problem such as difficult, the invention provides a kind of is medium with D5, without the need to any auxiliary agent in dyeing course, adopt in pure DISPERSE DYES and contaminate, dyestuff dye-uptake is high, the pad-dry-cure dyeing method that uniform dyeing property is good.
The technical solution adopted for the present invention to solve the technical problems is:
Take D5 as a pad-dry-cure dyeing method for medium, the method comprises the steps:
(1) preliminary treatment: before dacron enters dye, fabric being immersed temperature is soak 0.5-2.0 hour in the water of 20 DEG C-90 DEG C, then takes out fabric, dries 5-30 minute under temperature 20 DEG C of-50 DEG C of conditions;
(2) pad-dry-cure dyeing: get a certain amount of pure DISPERSE DYES and add in dyeing medium D5, the consumption controlling dyeing medium D5 makes to treat that dye fabric weight is 1:10-1:30 with the ratio of D5 medium total amount, pretreated dacron in step (1) is inserted in this dye bath, 90 DEG C-110 DEG C are warming up to this mixture system, constant temperature 5-10 minute, is then warming up to 180-200 DEG C and carries out pad-dry-cure dyeing.Dyeing can be carried out in the normal pressure dip-dye equipment of adding a cover, and is also applicable to High Temperature High Pressure and contaminates equipment;
(3) reduction cleaning of the rear fabric of dyeing: fabric after dyeing is carried out reduction cleaning according to GB2394-80 method.The formula of cleaning fluid is bath raio 1:60; Sodium hydrosulfite: 1.5g/L; NaOH: 30%, 3.0ml/L; Detergent 209:2g/L; Temperature 80 DEG C; 10 minutes time.
As preferably, in described step (1), pretreated process is: fabric processes 1.5 hours in 30 DEG C of water temperatures, then dries 30 minutes under 25 DEG C of conditions.
As preferably, in described step (2), the quality of pure DISPERSE DYES is the 1%-8% of dacron quality.
As preferably, in described step (2), dyeing course is as follows: enter dye under room temperature, be warming up to 90 DEG C with 3 DEG C/min, is then warming up to 190 DEG C with 2 DEG C/min and constant temperature carries out hot melt fixation in 30 minutes, carries out reduction cleaning after cooling to 60 DEG C with 2 DEG C/min.
As preferably, the dyeing machine that described step (2) adopts is exhaust dyeing equipment, comprises overflow dyeing machine, jet dyeing machine, axial flow dyeing machine etc.
The method adopts and replaces aqueous medium used in conventional disperse dyestuff pad-dry-cure dyeing to Eco-friendly decamethylcyclopentaandoxane (D5), and utilize the characteristic that D5 boiling point is high, air dielectric is replaced with D5 in the hot melt fixation stage, this technology in dyeing course without the need to any dispersing aid, and dye compared to conventional hot melt, whole dyeing course is simple, reaches good Color.
The dyeing medium that the present invention adopts is decamethylcyclopentaandoxane, and its structural formula is:
The present invention, by adopting above technical scheme, reaches following remarkable result:
(1) dyeing main process of the present invention carries out in non-aqueous media, can save a large amount of dyeing water.
(2) dyeing course of the present invention is without the need to adding any auxiliary agent, and midway is without the need to padding operation, and operating process is simple.And replace traditional air dielectric by the hot melt fixation stage with decamethylcyclopentaandoxane, the distillation of dyestuff can be reduced, improve the utilization rate of dyestuff, reduce the pollution to dyeing installation.
(3) decamethylcyclopentaandoxane of the present invention has certain dissolving and dispersibility to DISPERSE DYES, and there is good affinity to dacron, therefore dyeing course can reach good level-dyeing property and dye-uptake without the need to adding dispersant, thus also saves auxiliary agent use cost while minimizing discharge of wastewater.
(4) dyeing medium decamethylcyclopentaandoxane of the present invention colourless odorless nontoxic, can degrade, to environment and body harmless, and can to recovery, the recycle that can be realized decamethylcyclopentaandoxane medium residual night by extraction after dyeing.
