| 摘要 | A method for coloring fibers or fibrous structures composed of phenolic resins, which comprises applying a dye liquor to the fibers or fibrous structures, and then contacting them with a vapor of at least one compound selected from the group consisting of N,N-dialkyl acetylamides, dialkyl sulfoxides, ketones, alcohols, aliphatic amines and dioxane, or a mixed vapor of such compound and water. | ||||||
| 权利要求 | 1. A METHOD FOR COLORING FIBERS OR FIBROUS STRUCTURES COMPOSED OF PHENOLIC RESINS, WHICH COMPRISES: A. APPLYING A DYE LIQUOR TO SAID FIBERS OR FIBROUS STRUCTURES; B. DRYING THE RESULTING FIBER OF FIBROUS STRUCTURES; AND C. CONTACTING THE DRIED FIBER OR FIBROUS STRUCTURES WITH A MIXED VAPOR OF WATER AND AT LEAST 5% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF THE MIXED VAPOR, OF BENZYL ALCOHOL. 2. The method of claim 1 wherein said mixed vapor is maintained at a temperature of 100*C. to 150*C. 3. The method of claim 1 wherein said fibers or fibrous structures are contacted with said mixed vapor for 20 to 120 minutes. 4. The method of claim 1 wherein said dye liquor is a solution, emulsion or paste containing a dye. 5. The method of claim 1 wherein said dye liquor contains a disperse dye, azoic dye, cationic dye or vat dye. 6. The method of claim 1 wherein the dye liquor is applied by padding or printing. 7. A method for printing fibrous structures composed of a phenolic resins, which comprises: a. applying an aqueous paste containing a dye to said fibrous structures; b. drying the resulting fibrous structures; and c. contacting the dried fibrous structures with a mixed vapor of water and at least 5% by weight, based on the total weight of the mixed vapor, of benzyl alcohol at a temperature of 100*C. to 150*C. for 20 to 120 minutes. |
