Abstract:
(EN) A process for producing an elastic fiber comprising: melt-spinning a raw material composition, which comprises a thermoplastic polyurethane elastomer, at a spinning rate of 2,500 m/min to 10,000 m/min. The thermoplastic polyurethane elastomer comprises soft-segments obtained by reacting a polyether polyol as a long chain polyol.
(FR) L'invention concerne un procédé pour la production d'une fibre élastique, comprenant : le filage à l'état fondu d'une composition de matière première, qui comprend un élastomère de polyuréthane thermoplastique, à une vitesse de filage de 2 500 m/min à 10 000 m/min. L'élastomère de polyuréthane thermoplastique comprend des segments souples obtenus par réaction d'un polyol de polyéther en tant que polyol à longue chaîne.
