| Abstract: | Using NaSCN as solvent, flat acrylic fiber was produced by two-step wet spinning process. The selection of spinneret shape and the optimization of process conditions were discussed. It was considered that the key to the production of flat acrylic fiber lies in the selection of a flat spinneret hole with a certainL/D ratio. TheL/D ratio should be increased as great as possible. The practical experiments showed that the flat acrylic fiber with the ratio of length and width of above 6∶1 could be produced under the optimal formation conditions and after-processing conditions. |
