Agent for treatment of paper machine press section felts and its use |
摘要 |
An agent for treatment of paper machine press section felts is described which comprises one or more anionic polymers having a weight average molecular weight of 500 to less than 5000 selected from polycarboxylic acids and derivatives thereof, and/or 2-phosphino-1,2,4-tricarboxybutane. The novel agent, which preferably comprises a surfactant, inhibits the blinding of paper machine press section felts and provides improved felt conditioning at much lower concentration levels than known commercial products.
