Carbodiimide-modified polyester fiber and preparation thereof |
| abstract |
Abstract There are described polyester fibers and filaments which, following reaction with carbodiimides, have capped carboxyl end groups, the carboxyl end groups being predominantly capped by reaction with mono- and/or biscarbodiimides which are present in the fibers and filaments in an amount of from 30 to 200 ppm, based on the weight of the polyester, the free carboxyl end group content being less than 3 meq/kg of polyester, and the fibers and filaments additionally containing at least 0.02 percent by weight of at least one free polycar-bodiimide or of a reaction product containing still reactive carbodiimide groups, and also a process for the preparation thereof. The filaments described are suitable in particular for producing papermaker's machine wire-cloths. |
