| 摘要 | Process for dyeing textile materials of natural or synthetic fibers alone in mixture with each other, by treating the fibrous material with a solution of suitable dyestuffs in anhydrous, liquid ammonia alone or in mixture with low boiling organic solvents, within the range below the boiling point of the dyebath, and fixing the dyestuffs applied after removal of the ammonia remaining in the material in known manner typical for the dyestuffs or the dyegoods used. | ||||||
| 权利要求 | 1. IN A PROCESS FOR DYEING TEXTILE MATERIALS OF NATURAL OR SYNTHETIC FIBERS ALONE OR IN MIXTURE WITH EACH OTHER, THE IMPROVEMENT WHICH COMPRISES APPLYING TO THE FIBROUS MATERIAL A DYESTUFF DISSOLVED IN A MIXTURE OF ANHYDROUS, LIQUID AMMONIA AND HALOGENATED HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF METHYLENE CHLORIDE, CHLOROFORM, AND A COMBINATION THEREOF. 2. The improvement defined in claim 1, wherein the dyestuff solution is applied by dipping, padding or spraying. 3. The improvement defined in claim 1, wherein the dyestuff applied is fixed by heat. 4. The improvement defined in claim 1, wherein the dyestuff is a cationic dyestuff. 5. The improvement defined in claim 1, wherein the dyestuff is a dyestuff containing fiber-active groups. 6. The improvement defined in claim 1, wherein the dyestuff is a disperse dyestuff or a water-insoluble organic pigment dyestuff. 7. The improvement defined in claim 1, wherein the dyestuff is an acid dyestuff. 8. The improvement defined in claim 1, wherein the dyestuff is a water-soluble anionic or non-ionic dispersed metal complex dyestuff. 9. The improvement defined in claim 1, wherein textile material is a synthetic polyamide. 10. The improvement defined in claim 1, wherein the textile material is a linear polyester. 11. The improvement defined in claim 1, wherein textile material is polyacrylonitrile. 12. The improvement defined in claim 1, wherein the textile material is natural regenerated cellulose. |
