Abstract

Se describe un método para fabricar un hilo de núcleo elástico (50), en donde un núcleo elástico (30) que comprende una fibra (10) de caucho natural con un recuento métrico de 200-1000 dtex está cubierto por un hilo de cobertura a base de algodón (40), comprende una etapa de transportar el núcleo elástico (30) y el hilo de cobertura (40) de tal manera que el hilo de cobertura (40) alcance lateralmente una proximidad del núcleo elástico (30) en un espacio de la envoltura (35); una etapa de enrollar helicoidalmente el hilo de cobertura (40) alrededor del núcleo elástico (30) en un espacio de enrollado (35), en donde la velocidad de transporte, y por lo tanto la velocidad de enrollado/desenrollado, se selecciona de manera que el núcleo elástico (30) se estire hasta una relación de estiramiento de al menos 2, y de tal manera que, durante esta etapa de enrollado, el hilo de cobertura (40) se retuerza con una dirección de torsión final opuesta a su dirección de torsión inicial, y forma un número T de vueltas por unidad de longitud de la fibra elástica (10) establecido entre un valor mínimo predeterminado T0 y un valor máximo predeterminado T1, ambos en dependencia de la densidad de masa lineal Nm del hilo de cobertura (40), el espacio de enrollado (35) está encerrado por un contenedor (67). Un hilo elástico obtenido de esta manera, y un tejido, en particular un tejido tipo mezclilla, fabricado a partir de este hilo. (Figura 1)
