There is described a process for making a texturized polycapronamide yarn wherein the yarn is spun at a spinning speed below 1500 metres per minute and then subjected to a drawing and texturizing treatment including drawing, false twisting and heat treatment operations. The process is noted in that no more than two of said operations are carried out concurrently at least when the processing of the yarn is being started and the heat treatment is carried out under temperature conditions such as to set the false twist. There are also described the polycapronamide fibres and yarns texturized and manufactured by carrying out the process. |
