Title: The Innovations of Herbert Zeitler
Introduction
Herbert Zeitler is a notable inventor based in Grossaitingen, Germany. He has made significant contributions to the field of polyester fibers and filaments, holding a total of 4 patents. His work focuses on enhancing the properties of polyester materials, particularly for industrial applications.
Latest Patents
Zeitler's latest patents include innovative developments such as "Carbodiimide-modified polyester fiber and preparation thereof." This patent describes polyester fibers and filaments that, after reacting with carbodiimides, possess capped carboxyl end groups. The carboxyl end groups are predominantly capped through reactions with mono- and/or biscarbodiimides, present in the fibers and filaments in amounts ranging from 30 to 200 ppm based on the weight of the polyester. The free carboxyl end group content is maintained at less than 3 meq/kg of polyester. Additionally, the fibers and filaments contain at least 0.02 percent by weight of a free polycarbodiimide or a reaction product with still reactive carbodiimide groups. These filaments are particularly suitable for producing papermaker's machine wire-cloths. Another significant patent is for "Hydrolysis-resistant polyester fibers and filaments, masterbatches and a process for their production." This process involves creating hydrolysis-resistant polyester fibers and filaments, especially monofilaments for use in paper-making machine sieves, by feeding a masterbatch of a polymeric carrier and an end group blocking agent to a spinneret along with thread-forming polyester material.
