Silk would not generally spring to brain in relation to a business identified globally for excellent administration in standard yarn spinning – but there is a chapter on silk in the Uster story that absolutely deserves to be highlighted. It’s about a male who was focused to silk and its use as a fragile fiber for the finest yarns and awesome fabrics. This appear into an exciting historical past is offered to honor the existence and work of a genuine silk expert.

The calendar year 1948 was a main milestone for Uster Technologies, as the 1st yarn evenness tester was introduced to the current market. Peter Haettenschwiler was an assistant concerned in the enhancement of the tester and then in displaying the diagrams and examination benefits to spinners. In fact, he introduced top quality administration to the mills, where the diagrams were being found as aids to correct pricing, improved excellent and forecasting how the yarns would fit processing stages. In this function, he turned Uster’s 1st textile technologist.

Haettenschwiler also experienced a pretty unique hobby. He collected bagworm moths and butterflies. His understanding and determination permitted him to assemble the world’s largest assortment of moths of the family recognised as bagworm moths, today housed in the Entomological Collection of ETH Zurich, Switzerland. He turned a identified pro on this species, and 1st discovered and named about 30 new kinds not beforehand recorded. He also edited a lot of professional literature, enhancing his name and popularity among the intercontinental professionals in the discipline of Lepidoptera.

Silk is usually praised as ‘the queen of all textile fibers and purely natural wonder. It is no surprise, thus, that the top quality parameters of spun silk fibers were being of interest. Haettenschwiler analyzed silk spun yarn, but it will have to be claimed that it was some a long time together in the manufacturing of raw and spun silk right up until the 1st trials had been built with commercially offered tests devices. In the program of this get the job done, cooperation with authorities from silk institutes in Switzerland, Italy, and later on China was started off.

The European silk trade was the first to listen to about the new check systems. Early experiments rapidly showed that even really fine silk could be analyzed soon after selected diversifications of the devices. The exam final results ended up a lot more neutral, more significant, and far more exact than the information acquired with common screening solutions.

Centered on the check benefits, certificates had been issued, and these were used to set the commercial values of the items. It was specifically important for each trade and the subsequent remedy processes that the exam effects had been precise, so interest was carefully centered on optimizing the testing techniques.

The height of the silk organization

At the starting of the 18th century, the ‘silk courts’ in Zurich have been environment-famous and by 1900 the silk business was a person of the most significant industries in Switzerland. Silk processing attained its peak at the commencing of the 20th century. What stays currently are a handful of silk producers concentrating on specialized niche marketplaces, as nicely as Testex, established as `Zuerich Seidentrocknungsanstalt´ (establishment for silk drying) 175 a long time in the past and the economic institutes which arose to deliver money to assist the industry’s gains.

Silk has never been a big organization for Uster – only a area of interest for which Haettenschwiler showed his enthusiasm. There have been Uster Data editions for both spun silk and raw silk, even so, not incredibly, as Haettenschwiler also played an excellent part in building Uster Statistics in its early yrs and through the a long time. This story opens another website page of Uster record.

Haettenschwiler died this yr on August 17. “He was a formative identity for the enterprise and a extremely engaged colleague who devoted his doing work existence to the textile sector with respect to sophisticated excellent management in staple and filament spinning. Silk was one particular of his great passions and the improvement of doable aim excellent testing alternatives with Uster goods was often his intention and he was generally pushing for investigations and publications,” states Wolfram Soell, Senior Textile Technologist at Uster Systems AG. “We would like to honor his doing the job life and we should really inspire potential generations of textile specialists with his tale.”
