| titleOfInvention | A kind of preparation method of flat fiber |
| abstract | The present invention relates to a kind of preparation method of flat fiber, adopt dry-jet wet spinning technique, spinning solution enters the first coagulating bath after circular spinneret orifice is extruded, and spinneret draft ratio is 2 ~ 10 times, and the solvent gone out in coagulating bath strand is 25 ~ 50wt%; Then in the second gelation, solidify stretching, described solidify stretching and refer to and to stretch in continuation process of setting; Again through washing, and carry out drying stretching, prepare flat fiber.The present invention obtains flat fiber and has excellent performance, as all characteristic in gloss, elasticity, anti-pilling, bulkiness and feel etc., the good rigidity of flat fiber is when being used as filtering material, general circular-section fibers can be formed to be beyond one's reach gas channel size and form, in particular/special requirement Application Areas, also there is very large development space. |
