Title: Eberhard Teufel: Innovator in Cigarette Filter Technology
Introduction
Eberhard Teufel is a notable inventor based in Gundelfingen, Germany. He has made significant contributions to the field of cigarette filter technology, holding a total of 8 patents. His innovative work focuses on creating environmentally friendly and high-performance cigarette filters.
Latest Patents
One of his latest patents is for a disintegratable cigarette filter. This invention relates to a high-performance cigarette filter made from cellulose ester fibers or filaments that can be mechanically disintegrated. The filter is characterized by a fiber weight to draw resistance ratio greater than approximately 0.7, a residual crimping value not exceeding 1.45, and a fiber weight of no more than 10 mg/mm of filter length. Additionally, the hardness of the cigarette filter is higher than approximately 90% filtrona hardness, which enhances its disintegratability under environmental conditions compared to similar products.
Another significant patent involves a melt-blown non-woven fabric based on cellulose esters. This fabric features fibers with a mean diameter of less than about 10 microns and contains 0-10 wt. % extractable softener. The production process involves mixing cellulose acetate with a softener, heating, and melting the mixture, which is then processed into a melt-blown non-woven fabric. This innovative fabric is particularly suitable for use as filter material.
