New micro-sphere application in the leather industry / Dietrich Tegtmeyer in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CII, N° 9 (09/2007)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CII, N° 9 (09/2007) . - p. 288-292 Titre : New micro-sphere application in the leather industry Type de document : texte imprimé Auteurs : Dietrich Tegtmeyer, Auteur ; F. Silberkuhl, Auteur ; C. Tysoe, Auteur ; W. Zeyen, Auteur ; O. Vorlaender, Auteur Année de publication : 2007 Article en page(s) : p. 288-292 Langues : Américain (ame) Résumé : The upgrade of lower quality hides or skins in order to produce a good quality leather article with acceptable yield and performance is one of the most value adding opportunities for a tanner. A new, innovative wet end technology based on expandable Micro-spheres is being introduced to the leather industry. Tanned leather is treated during the retanning step with a customized penetrating polymer dispersion containing compact micro-spheres. These Micro-spheres have a diameter of 5 - 20 µ and are small enough to migrate into the collagen structure; they are filled with a liquid gas, and can expand through a heat treatment process, up to 40 times of their original size to a much larger, resilient Micro-cell. During the wet end process the polymer together with the micro-spheres penetrate into the leather. After a conventional retanning and drying process the dried crust is then be subjected to a special steam treatment where the Micro-spheres inside the leather are expanded and transformed into larger Micro-cells. This operation results in a dramatic upgrade of the internal structure of the leather, and in turn the grain surface appearance and uniformity, too. The loose areas, blood vessels and other voids in the corium layer are selectively and permanently filled while keeping the leather light and soft. Several applications have already been studied and the feasibility of the technology has been proven, but this new system further opens up a variety of completely new opportunities for the leather industry.

The 56th John Arthur Wilson lecture sustainability - The passport to our future / Dietrich Tegtmeyer in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CX, N° 8 (08/2015)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CX, N° 8 (08/2015) . - p. 240-250 Titre : The 56th John Arthur Wilson lecture sustainability - The passport to our future Type de document : texte imprimé Auteurs : Dietrich Tegtmeyer, Auteur Année de publication : 2015 Article en page(s) : p. 240-250 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Cuirs et peaux -- Industrie -- Aspect de l'environnement Développement durable Durée de vie (Ingénierie) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : For the past ten years I have participated in many discussions about sustainability around the leather world. In today’s John Arthur Wilson lecture I will attempt to summarize key points I learned during this time in symposiums, readings, debates and various companies programs. I also did some research for this presentation ; one book by Iris Publé has me inspired most ; and many of the statements in this lecture are somehow linked to thoughts and theories of this book. If I didn’t made always a correct reference it is not done by purpose and a result of translation. The title for this speech – Sustainability, the passport to our future – was inspired by a comment I picked up in a shoe sustainability summit last year in Shanghai; I made a note, because I found it a good fit, at least to my understanding of this. In terms of sustainability we need to see our planet as one single bio-dome. Recently Alexander Gerst, a German astronaut from my hometown Cologne, was for the first time in his life aboard the ISS space station. After arrival I was listening to an interview with him via satellite on our local radio station and I found it remarkable what he said. He was speaking about his thoughts when he was sitting the first time here, on this famous place in the station, looking out of the window and watching the incredible view of our planet Earth. He said "I was looking for hours, it was completely silent... first I thought, how wonderful our planet is, so colorful, so perfect, so nicely placed in this dark orbit. Then looking in the endless universe I became aware how small our planet earth actually is ; what a tiny part in this huge black orbit.” "But then", he said, and this really attracted my attention, "I became aware how sensitive and how fragile our planet really is. I have seen the tiny blue layer of atmosphere around the planet, which actually is our life saving protection shield between the warm climate on earth and the black, cold death in the universe. Without this magic safety membrane everything would be dead, and it is so thin, it can be destroyed so easily. Therefore, it up most important for everyone in everything what we do to maintain and preserve this life saving atmosphere". With this introduction I wanted to attract your attention to this lecture and try to project you, for the next hour, on a level outside our day-to-day world and local problems, to observe sustainability issues from a real global perspective. Sometimes this helps to adjust our compass ; as the Apollo astronaut Eugene Cernan has put it in nice words, being 400 000 km away from the earth : "We left to explore the moon, but actually we discovered the planet earth". In the last 100 years the economy was driven by growth and innovation optimism. Inventors and researcher of course didn’t know, where all the developments would finally end up, but the playground was so big and discoveries have been so interesting and fascinating, that the development process was perpetuating and couldn’t be stopped or redirected. Unfortunately during this rapid innovation and development process both public health and the environment suffered, they were not the focus for a long period of time.
