| titleOfInvention | High-strength polymetaphenylene isophthalamide yarn and production thereof |
| abstract | PURPOSE: To obtain the titled yarn efficiently, by spinning dope consisting of a specific polymetaphenylene isophthalamide and subjecting prepared yarn to water washing and water bath drawing processes under specific conditions, respectively. n CONSTITUTION: A polymetaphenylene isophthalamide polymer having ≥95mol% repeating unit consisting of methaphenilene isophthalamide and 0.7W2.5 intrinsic viscosity is dissolved in an organic solvent to form spinning dope and further the dope is spun to give undrawn yarn. Then, the undrawn yarn is washed with water, subjected to a primary water bath drawing process and drawn by one state at 1.1W1.5 draw ratio. Successively the drawn yarn is washed with water, subjected to a secondary water washing drawing process, drawn by one stage at ≥1.1 draw ratio, further dried and subjected to dry heat drawing process and drawn at 4.0W7.0 draw ratio as total draw ratio to give the aimed yarn. n COPYRIGHT: (C)1987,JPO&Japio |
