| titleOfInvention | Method for producing uncrimped short fibers |
| abstract | An object of the present invention is to provide a method for producing high-quality uncrimped short fibers with high productivity. A tow obtained by converging one or a plurality of unstretched multifilaments after spinning is continuously stretched without collecting cans, and the surface temperature of at least one of the rollers at the time of stretching Is 120 ° C. or less and the total draw ratio is 1.5 to 5.5 times, and then overfeed is performed, and the surface temperature of at least one of the rollers during the overfeed is 140 to 240 ° C. In addition, a method for producing uncrimped short fibers is characterized in that overfeeding is performed at a total draft ratio of 0.88 to 0.98, and the drawn tow is continuously cut to a length of 1 to 35 mm.
