Abstract
A paper machine fabric INCLUDES A fabric having a roll side and a paper side and a surface matrix on the paper side; and a chrome complex treatment in the surface matrix. The chrome complex treatment chemically reacts with the surface matrix and orients hydrophobic organic chains away from the surface of the fabric and thereby provides enhanced release property.
Claims7
A paper machine fabric, comprising:
- a fabric having a roll side and a paper side and a surface matrix on the paper side;
- and
- a chrome complex treatment in the surface matrix.
A method for providing release properties to a papermaking machine fabric, comprising the steps of:
- applying a solution of chemically reactive chrome complex to a surface of a papermaking machine fabric;
- and
- drying and curing the fabric so that the complex reacts with the surface and produces a polymerized chromium network chemically bonded to the fabric.
