Abstract
After yarn is loaded into basket inside high-pressure dyeing cauldron, condensed CO2 liquid is pumped into the cauldron and dye liquid is fed to the cauldron and basket for dynamic dyeing, with the pressure being controlled in 30 MPa minus or plus 400 Pa and the temperature in 170 minus or plus 10 deg.c. CO2 liquid and dye liquid flowing out of the cauldron is filtered to eliminate impurities and separated in separator to obtain residual dye liquid, and CO2 gas is dried in molecular sieve and fed back to CO2 mixer for circular use. The said method has the advantages of no waste liquid and thus no waste liquid treating investment and capability of obtaining dyed yarn product with bright color. When 3-8 dyeing baskets are installed parallelly inside high-pressure dyeing cauldron, the dyeing process may be performed continuously.
Description
The present invention relates to yarn dyeing technology, particularly supercritical carbon dioxide yarn dyeing technology.
At present, the yarn dyeing of prior art all is to adopt the wet type decoration method, and dry dyeing also is in conceptual phase, and the shortcoming of wet method dyeing is to handle a large amount of waste water, and investment cost is very big, if untimely processing serious environment pollution then.Therefore it is little or do not have waste water and be different from the so-called dry method of expense costliness to seek wastewater treatment capacity, is the problem of current research.
The object of the present invention is to provide a kind of supercritical carbon dioxide yarn dyeing technology, its advantage is no waste water, the almost break-even up-to-date dyeing of dyestuff.
Embodiment of the present invention are as follows: behind the dyeing charging basket in yarn coil is packed the high pressure dyeing still into, with fresh O
2Reclaim CO with the circulation that comes from mole sieve drier
2After blender mixes, be condensed into liquid CO by cold doubtful device
2, through the pump pressurization, when pressure reaches 300 * 10
5During ± 400 handkerchiefs, be heated to through preheater and enter the dyeing charging basket of in the dye solution groove dyeing liquor being brought in the high pressure dyeing still after 170 ± 10 ℃ and dynamically dye, the CO that comes out from the high pressure dyeing still
2Enter filter with dyeing liquor.Enter separator behind the elimination impurity again, isolate liquid, CO
2Gas then after molecular sieve drying, in blender with replenish fresh CO
2Mix, so circulate, open the high pressure dyeing still after the dyeing and the dyeing charging basket takes out yarn, in the general high voltage dyeing caldron and multi pack 3-8 dyeing charging basket, each dyeing charging basket takes turns driving by the valve switching, dyes continuously guaranteeing.
Below preference in conjunction with flow chart the present invention is described in detail, but do not mean that and limit the scope of the invention.
Fig. 1 is a supercritical carbon dioxide yarn dyeing flow sketch of the present invention.
Example 1,5 kilograms of the polyester yarn balls of string of packing into earlier in high pressure dyeing still 6 are with fresh CO
2Feed CO
2In the blender 1, start condenser 2 (feeding cold-producing medium) pump 3 and preheater 4, as fluid CO
2Pressure be 300 * 10
5When ± 400 handkerchiefs, temperature reach 170 ± 10 ℃, with fluid CO
2By in the dyestuff liquid bath 5 disperse dyes and auxiliary agent etc. being brought into the dyeing charging basket 10 in the high pressure dyeing still 6, this fluid CO
2And dye solution in dyeing charging basket 10 by repeatedly by around the middle mind-set and by all around after center flow with yarn dyeing, the fluid CO that comes out from high pressure dyeing still 6
2And dyestuff feeds filter 7, enters separator 8, gas CO after filtering out impurity
2By behind the mole sieve drier 9, enter CO again
2Blender 1, so circulation was generally circulation 10-20 minute till dyeing fully, stopped logical CO then
2, open high pressure dyeing still 6 and dyeing charging basket 10 and will dye good line yarn taking-up, dye next time.A dyed yarn ball of string is bright-colored, firm.
Example 2 replaces outside the polyester yarn divided by cotton, and all the other conditions are identical with example 1, and the gained dyed yarn is beautiful in colour, firm, brilliant.
Be to be example to adorn a dyeing charging basket in the high pressure dyeing still above, be actually 3-8 platform in parallel dyeing charging basket, only logical valve switches and just can dye continuously.
Advantage of the present invention is: no waste liquid is removed expensive liquid waste processing investment from, secondly is CO2Can follow Ring uses, almost not waste. The dyed yarn color is gorgeous, and is suitable for the yarn of various quality. The high pressure dyeing still 3-8 platform dyeing charging basket of generally can parallel connection packing into switches by valve, just can be continuous Change operation.
