Title: Celebrating the Innovations of Inventor Bernard Millaud

Introduction

Bernard Millaud, an accomplished inventor based in Beaurains, France, is recognized for his significant contributions to the field of material science. With a total of two patents to his name, Millaud's work focuses primarily on enhancing the properties of polyethylene terephthalate, leading to advancements in fiber technology.

Latest Patents

Millaud's latest patents include a groundbreaking process for obtaining modified polyethylene terephthalate that is pilling-free. The invention details a method in which polyethylene terephthalate is continuously modified by incorporating silicon dioxide (SiO) groups in a specific range of 300-700 ppm of Silicon during the direct esterification of terephthalic acid and ethylene glycol. This innovative approach is followed by polycondensation, which employs methoxyethyl silicate or propyl silicate at key stages—when the prepolymer achieves a weight-average molecular mass between 9,000 and 16,000 and a polydispersity index of 1.5 to 2. The process operates under conditions of 260 to 290 degrees Celsius and a pressure between 1.5 and 2.5 bars, with a minimum reaction time of 5 minutes. This patent not only improves the production of modified polyethylene terephthalate but also introduces pilling-free fibers, significantly enhancing their durability and aesthetic quality.
