IPC: D06M101/06
Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for rational and uniform aromatic acylation of a cellulose-based fiber product. SOLUTION: A cellulose-based fiber product containing a cellulose fiber is added with an aqueous solution of an alkali and dried to substantially remove water. Then the cellulose-based fiber product is added with a nonaqueous solution containing an aromatic acylating agent. In the operation, both the solid alkali and the aromatic acylating agent exist in the cellulose-based fiber product and the cellulose-based fiber product is in a state substantially not containing water. In this state, the cellulose-based fiber product is added with water. The aromatic acylation reaction of the cellulose fiber is advanced by the application of water. A water immersion-pressing method, a water spraying-pressing method or a water permeation method under pressure, or the like, are preferably adopted as the method for providing the cellulose-based fiber product with water.  The method is that compulsorily forcing water into the interior of the cellulose-based fiber product. By this method, the aromatic acylation on the surface and into the interior of the cellulose-based fiber product can be more uniformly carried out.
