Scale inhibitor
Kayaclean AS |
Kayaclean AS can reduce the number of times machine cleaning operations need to be carried out.
 Characteristics
Scale inhibitor
| • |
Kayaclean AS is effective in the elimination of problems associated with the hardness of the water used or impurities attached to fibers during the dyeing of natural and synthetic fibers. This
agent is especially effective in the prevention of scum. |
| • |
Dispersal chelating ability is acidic and thus effective under dyeing conditions, preventing problems associated with metal ions during dyeing. |
| • |
Effective in the dipersal of insoluble inorganic materials such as silica scale, preventing them from fixing to fibers. |
| • |
Since it is capable of dispersing alkali sizing agent and preventing the accretion of coagulations of polyester oligomer, this agent prevents re-deposition on the treated article, thus raising
the quality of the product. |
