Sumifix HF dyes suitability for mixed dyeing
| |
Notes |
| Polyester/cotton, polyester/rayon, polyester/tencel |
Good color reproducibility |
| Nylon/cotton, nylon/rayon, nylon/tencel |
Less nylon-staining with the use of anti-staining agents |
| Cotton/rayon, cotton/tencel |
Excellent tone in tone property |
| Cotton/wool, rayon/wool |
Optimum dyeing method currently under research |
| Cotton/spandex, rayon/spandex, tencel/spandex |
Hardly any uneven dyeing caused by fabric distortion esp. in spandex mixtures |
In mixed dyeing...
1) Large liquor ratio is required when cotton content is small
| Example: Using the same dyeing machine |
Cotton 100%,
liquor ratio 1:20 |
 |
Cotton 40% mixture,
liquor ratio 1:50 |
2) When cotton proportion is uncertain in the mixture,
the dyeability of the trichromatic colors needs to match even with a large liquor ratio
Liquor ratio dependency (1:20 - 1: 100)
