Characteristics
Protecting agent for disperse dyestuffs in dyeing
| • |
KP Leveler prevents the effect of hardness and metal salts (copper, iron) in the water used during the dyeing of natural and synthetic fibers, contributing to the elimination of problems during
dyeing, being especially effective in the prevention of scum, etc. |
| • |
Do not use in conjunction with direct dyestuffs. |
| • |
Effective in improving the reproducibility of dyeing with quinone dyestuffs for which color changes readily occur due to the influence of metal salts (copper, iron). |
| • |
Since solution containing this agent is weakly acidic (with a pH in the range 5~6), KP Leveler CUF is suitable for use in weakly acidic dyeing. |
