What does this K9 guide confirm
K9 identifies the potato CMS grade in the verified KARN textile range Both powder and flake can be requested The published K9 flake result is nominal viscosity 42000 mPa s with a confirmed range from 37800 to 46200 mPa s when the same 5 percent solution NDJ 8 spindle number 4 and 6 r min method is used
Verified K9 facts
| Raw material | Potato |
|---|---|
| Degree of substitution | 0.4 |
| Available forms | Powder and flake |
| Public flake range | 37800 to 46200 mPa s |
When to request K9 powder information
K9 powder is available but the public K9 flake viscosity range does not define its powder specification Confirm powder characteristics packing and process fit through the current KARN TDS and a representative sample before setting a production requirement
When the K9 flake range can be compared
Compare a K9 flake result only after matching the material form solution concentration instrument spindle and rotational speed to the published method A number outside that controlled context is not a comparable K9 result
What to include in a K9 evaluation request
- Textile printing process
- Fabric and recipe context
- Required powder or flake form
- Target viscosity or test conditions
- Sample or batch reference when available
What still needs current TDS confirmation
K9 pH solubility powder specifications packing and grade specific process suitability are not confirmed by this guide Request the current KARN TDS and evaluate a representative sample before a production decision
