Process for dyeing undrawn acrylonitrile polymer filaments |
| abstract |
Process for dyeing substantially undrawn dry-spun filaments of acrylonitrile polymer which comprises extracting spinning solvent from moistened dry-spun filaments of acrylonitrile polymer to below 10% by weight of the filaments and at below 80 DEG C., dyeing the extracted filaments in a dye bath at below 80 DEG C. by initially contacting the filaments with the dye at nearly zero stretch, followed by stretching the filaments from 1.5x to 4.5x at between 60 DEG - 80 DEG C. while still contacting the dye solution. |
