METHOD OF IMPROVING PAPER MACHINE FABRIC PERFORMANCE |
| 摘要 |
Methods are provided for improving the papermaking process. In various embodiments, the methods include the application of alkali material in combination with an anionic polymeric dispersant and/or a hydroxyfunctional carboxylic acid to papermaking fabrics such that the application thereof removes contaminants from the papermaking fabrics and improves the drainage of said papermaking fabrics. Such alkali material in combination with an anionic polymeric dispersant and/or a hydroxyfunctional carboxylic acid can be applied as a single aqueous solution, and may further comprise a surfactant. |
