Method for physically dissolving plant fibre by adding solvents for two times |
| abstract |
The invention discloses a method for physically dissolving herbaceous plant fiber by secondly adding a solvent. The method includes the following steps: a herbaceous plant fiber pulp is ground and added into water solution of N-methyl morphine oxidation (NMMO) to prepare a suspension with proportion by weight between the herbaceous plant fiber pulp and the NMMO of 1: 4; the suspension prepared is distilled by pressure reduction; when mol ratio between the NMMO and water is 1: 4-5 in the suspension, solid NMMO powder is added into the suspension to cause that the weight percent of the herbaceous plant fiber pulp in the suspension reaches 10 percent to 16 percent; the suspension is again distilled by pressure reduction to cause that the herbaceous plant fiber pulp is completely dissolved. Raw materials of the invention have wide source; preparation time of the invention is short; and viscosity of the spinning solution obtained is lower, thereby being characterized by better spinnability and the like; herbaceous cellulosic fiber with various varieties and specification can be obtained. |
