| titleOfInvention | Polyester fibers modified with carbodiimides and process for their preparation |
| abstract | Polyester fibers modified with carbodiimides and process for their preparation Polyester fibers and filaments which contain carboxyl end groups closed off by reaction with carbodiimides, wherein - the closing off of the carboxyl end groups has predominantly been carried out by reaction with mono- and/or biscarbodiimides which the fibers and filaments still contain in the free form, however in as little an amount as less than 30 ppm (by weight) of the polyester, - the content of free carboxyl end groups is less than 3 meq/kg of polyester and - the fibers and filaments still contain at least 0.05% by weight of at least one free polycarbodiimide or a reaction product which still contains reactive carbodiimide groups, and a process for their preparation are described. The filaments described are particularly suitable for the production of paper making machinery screens. |
