The technical process (as shown in Figure 7) utilizing the supercritical fluid spray-dyeing yarn injector not with heating tube to carry out spray-painting is:
The first, the supercritical fluid media stream in supercritical fluid medium storage subsystem 12 generates subsystem 13 through supercritical fluid, generates the supercritical fluid meeting spray-painting process conditions.
The second, run along technological requirement direction by yarn dyeing line 11, successively through cleaning injector 15, dyeing injector 16 and rinsing injector 17.
3rd, after the fluid intake adapter 7 that the supercritical fluid pure supercritical fluid generated in subsystem 13 flows through cleaning injector 15 enters liquid distributing pipes 5, spray orifice distributor pipe 1 is sprayed into by straight spray orifice 3-E or oblique spray orifice 3-F, spray to by yarn dyeing line 11, it is extracted and cleans, to remove its impurity, the aperture that fluid leads mouth 2-A and 2-B by spray orifice distributor pipe 1 two ends high pressure is discharged, after entering the step-down of fluid pressure letdown chamber buffering, supercritical fluid and magazins' layout subsystem 18-1 is entered via fluid issuing adapter 8-A and 8-B, be stored in supercritical fluid medium storage subsystem 12 after treatment to recycle.
4th, after the fluid intake adapter 7 of the dyed injector 16 of the supercritical fluid flows being dissolved with dyestuff that dyestuff dissolves in subsystem 14 enters liquid distributing pipes 5, spray orifice distributor pipe 1 is sprayed into by straight spray orifice 3-E or oblique spray orifice 3-F, spray to by yarn dyeing line 11, realize its dyeing, the aperture that fluid leads mouth 2-A and 2-B by spray orifice distributor pipe 1 two ends high pressure is discharged, after entering the step-down of fluid pressure letdown chamber buffering, supercritical fluid and dye separation subsystem 18-2 is entered via fluid issuing adapter 8-A and 8-B, be stored in supercritical fluid medium storage subsystem 12 after treatment to recycle.
5th, after the fluid intake adapter 7 that the supercritical fluid pure supercritical fluid generated in subsystem 13 flows through rinsing injector 17 enters liquid distributing pipes 5, spray orifice distributor pipe 1 is sprayed into by straight spray orifice 3-E or oblique spray orifice 3-F, spray to by yarn dyeing line 11, rinsing is carried out to the dyestuff residued in above yarn 11, the aperture that fluid leads mouth 2-A and 2-B by spray orifice distributor pipe 1 two ends high pressure is discharged, after entering the step-down of fluid pressure letdown chamber buffering, supercritical fluid and dye separation subsystem 18-2 is entered via fluid issuing adapter 8-A and 8-B, be stored in supercritical fluid medium storage subsystem 12 after treatment to recycle.
When using the present invention to carry out supercritical fluid spray-dyeing yarn, straight spray orifice 3-E and the different-effect caused by oblique spray orifice 3-F are: when pure supercritical fluid or supercritical fluid dye liquor are sprayed into by oblique spray orifice 3-F, fluid time be sprayed on yarn in yarn cleaning chambers or spray-painting chamber or rinse chamber to be longer than when spraying into from straight spray orifice 3-E be sprayed on time yarn, fluid also can produce along yarn direct of travel and drag band effect to yarn simultaneously.So when pure supercritical fluid or supercritical fluid dye liquor are sprayed into by oblique spray orifice 3-F, fluid is better than effect when spraying into from straight spray orifice 3-E to the cleaning of yarn, the effect such as spray-painting effect and rinsing.
