| titleOfInvention | Method for preparing crosslinked cellulose acetate fiber with high-boiling amide as solvent |
| abstract | The invention discloses a method for preparing crosslinked cellulose acetate fiber with high-boiling amide as a solvent. The method for preparing the crosslinked cellulose acetate fiber with the high-boiling amide as the solvent is characterized by comprising the following steps: adding 21-44.5 parts of cellulose acetate flake with the substitution degree of 2-2.7 and the polymerization degree of 200-600, 0.5-2 parts of polycarboxylic acid, 0-2 parts of additive and 55-75 parts of high-boiling amide into a dissolving kettle with a stirrer and a thermometer, stirring and dissolving a mixture for 6-12 hours at 70-100 DEG C to form a uniform and stable spinning solution; defoaming the spinning solution, and keeping a constant temperature of 70-130 DEG C; and through a metering pump, extruding the spinning solution from a spinneret orifice with the diameter of 0.08-0.3 mm and the temperature of 70-130 DEG C, making a small flow enter a hot passage with the temperature of 130-230 DEG C, removing the solvent, performing crosslinking reaction, and winding at a speed of 200-400 m/ min to obtain the crosslinked cellulose acetate fiber. By the method, the problem caused by using acetone as the solvent is solved and mechanical properties of the fiber are improved; and the fiber can be used as a cigarette filtering material, a high-end textile material and a medical material. |
