| 摘要 |
The present invention relates to a process and a device for the production of bi-component yarns containing bilaminar and multilaminar filaments. Two polymer compositions are spun after feeding through a dichotomic mixer possessing tubes of identical internal diameter (5 to 25 mm), inside which 4 to 9 helical elements are placed in series, the leading edge of each of the elements being placed at 90 DEG relative to the trailing edge of the previous element. The process and device according to the invention can be used for all types of spinning, namely solution spinning, melt spinning, semi-melt spinning and the like. The yarns obtained contain only a minor proportion of monolaminar filaments. |
