With fixation.
（3）The pressurized CO for being heated to above-critical state2Enter in chassis 2 through tap hole 3 from mozzle, and be divided to each
In dyestuff divider passages 5, air-flow is passed through dyestuff net 4 and is fully contacted with dyestuff, is dissolved.
（4）When dyestuff is in the CO of above-critical state2Middle dissolving after reaching saturation, with CO2Fluid is thin by politef
Film 7 and protection network 6, enter in dyestuff kettle tank body, and then reaching dyeing pot carries out non-aqueous dyeing.
After non-aqueous dyeing is finished, will be left in taking out without the dyestuff of dissolving on dyestuff net 4, weigh remaining dyestuff matter
Amount, can further be precisely calculated the dyestuff yarn ratio of this dyeing, be next stain-accumulation experience.
A kind of specific embodiment for being carried out non-aqueous dyeing method using dyestuff kettle of the present utility model to washing yarn, first, is claimed
The appropriate disperse dyes of amount are blue, disperse dyes are red and the yellow each 2.5g of disperse dyes, are respectively put in 3 dyestuff divider passages 5, push up
Polytetrafluoroethylene film 7 in end seal.According to calculated experimental data before, block and need not breathe freely using closure bolt 8
Airflow hole 3.Dyestuff cylinder is installed to dyestuff kettle tank interior, and the supercritical CO 2 for reaching staining technique parameter is passed through by bottom
Fluid.Fluid flows through the abundant dissolving dye of dyestuff cylinder, after filtering through upper strata polytetrafluoroethylene film 7 and protection network 6, enters dyestuff
In kettle tank body, then reaching dyeing pot carries out non-aqueous dyeing.Place a mass in advance in dyeing pot yarn is washed for 800g, one section
After time, wash yarn and uniformly paint, occur without pattern phenomenon.As dyestuff is not mixed, after dyeing is finished, by dyestuff
Completely take out, weigh remaining dyestuff quality, further accurately calculate the dyestuff yarn ratio of this dyeing.
Certainly, described above is not that this utility model is also not limited to the example above to restriction of the present utility model, this
The those of ordinary skill of technical field, in essential scope of the present utility model, change, remodeling, interpolation or the replacement made,
Protection domain of the present utility model should also be belonged to.
