Abstract
La presente invención se refiere a una fibra elástica hilada en seco, mejorada, de polímero spandex de poliuretano-urea a base de poliéter, que tiene segmentos blandos y duros, polímero que es el producto de un copolímero terminado en hidroxilo de tetrahidrofurano y 3-metiltetrahidrofurano, que se terminó en un extremo con diisocianato orgánico y después se le extendió la cadena con la diamina, en donde la mejora comprende, que los extendedores de cadena sean una mezcla de dos diaminas, seleccionándose la primera diamina de etilendiamina, 1,3-propilendiamina y 1,4-ciclohexillendiamina y la segunda diamina es un coextendedor que se selecciona de 2-metilpentametilendiamina, m-fenilendiamina hidrogenada y 1,2-propilendiamina, el coextendedor es de 20 a 50 por ciento molar de la mezcla de diamina, y el segmento duro es de 5.5 a 9 por ciento molar del polímero.
