| 摘要 | A process for dyeing novoloid fiber without changing the thermal properties or altering the hand (textural quality or feel). After scouring and rinsing, the fabric is placed in an enclosed container with water, 1 - 5 grams per liter of a carrier such as Butyl benzoate and 0.10 - 10.0 per cent of a basic dye, such as Victoria Green Crystals. The pH in the container is maintained at approximately 4.5 to 6.5 with acetic acid or another suitable chemical. The temperature is raised at an approximate rate of 2 Farenheit degrees per minute from 100*F to 240* - 300*F and then held for at least 1 1/2 hours at that temperature. The container is cooled to 140*F - 180*F, rinsed until clear and the fabric removed. Finally, the fully relaxed fabric is extracted and framed dryed at 250*F - 350*F. | ||||||
| 权利要求 | 1. A PROCESS FOR DYEING AN UNMODIFIED NOVOLOID FIBER COMPRISING THE STEPS OF: A. PLACING THE FIBER IN AN APPORXIMATELY 100*F MIXTURE OF: 1 WATER, 2 1 TO 5 GRAMS PER LITER OF BUTYL BENZOATE DYESTUFF CARRIER, 3 0.1 TO 10.0 PER CENT BASED ON WEIGHT OF FIBER OF THE GROUP CONSISTING OF CATIONIC AND DISPERSED DYESTUFFS, 4 A SUFFICIENT QUANTITY OF A SUITABLE CHEMICAL FOR MAINTAINING A PH OF THE MIXTURE OF ESSENTIALLY 4.5 TO 6.5; B. HEATING THE MIXTURE TO A HIGH TEMPERATURE OF BETWEEN 240*F TO 300*F; C. HOLDING THE MIXTURE AT THE HIGH TEMPERATURE OF STEP (B) FOR AT LEAST 1 1/2 HOURS; AND D. COOLING THE MIXTURE AND FABRIC TO APPROXIMATELY 140*F TO 180*F. 2. A process as set forth in claim 1 wherein the chemical of step (a) (4) is acetic acid. 3. A process as set forth in claim 1 wherein the dyestuff is cationic. 4. A process as set forth in claim 3 wherein the cationic dyestuff is Basic Green 4. 5. A process as set forth in claim 3 wherein the cationic dyestuff is Basic Green 3. 6. A process as set forth in claim 1 wherein the dyestuff is dispersed. 7. A process as set forth in claim 6 wherein the dispersed dyestuff is Dispersed Violet 8. 8. A process as set forth in claim 6 wherein the dispersed dyestuff is Dispersed Yellow 64. 9. A process as set forth in claim 6 wherein the dispersed dyestuff is Dispersed Orange 59. 10. A process as set forth in claim 6 wherein the dispersed dyestuff is Latyl Brilliant Blue BLT. 11. A process as set forth in claim 6 wherein the dispersed dyestuff is Palanil Black. 12. A process as set forth in claim 6 wherein the dispersed dyestuff is Dispersed Blue 56. 13. A process as set forth in claim 6 wherein the dispersed dyestuff is Dispersed Red 91. 14. A process as set forth in claim 6 wherein the dispersed dyestuff is Palanil Blue RT. |
