In the interview, Senior Expert in R&D Technology, José Guadalupe Flores Molina provided information about the advantages of IDF on rotor spinning and in airjet spinning. IDF makes it possible to cut down the number of draw frames used in airjet spinning which is already a standard practice for rotor spinning to only have cards with IDF directly before the spinning machines. Whereas for airjet spinning, having one card and three draw frames is acceptable. By using the IDF and a 12-fold creel finisher, customers are able to shorten the preparation process – so they now only need one card with IDF and one finisher before spinning. That means they save space and energy because they need two fewer draw frames.
A research project in this field dated back to 2015, where a wealth of knowledge, insights and experience gained over time while conducting a number of trials at R&D center in Germany and on-site at Trützschler customers around the globe. As a result of these studies, it has proven that the short preparation process for airjet would work reliably which was tested during Itma Asia 2018 and Itma 2019. To set as an example, a continuous flow of orders for new airjet spinning projects using the short process recorded since then and the demand in India has even boomed.
When evaluating on shorter processes, the outcome depends on the spesific situation. At customer trials, where each application is technologically evaluated in advance, best results obtained with synthetics and yarn counts up to Ne 40 so far and there has been no difference recorded in the quality of the final fabric. As an example, a customer, who switched their production line to the short process using cards with IDF and 12-fold creel finishers, did not report any change in quality and placed a new order after a year for a mill with IDF VORTEX SPINNING.
Future Endeavors
The future looks promising for short spinning processes with IDF. New possibilities are sought to expand the field of application. Innovators are running tests to achieve finer yarn counts, while also working with different raw materials like Lyocell and blends.
The final comments was on the project overall which was welcomed by R&D technologist since there are still so many potential applications for airjet spinning where the short preparation process can be used to its full potential. And the wishes for the success of the new IDF 3 outlined whose impressive features can now be tested along the mills of IDF VORTEX SPINNING customers which is another source of proud.
Project Partner Murata, VORTEX Product Manager Mr. Masazumi Shigeyama said the following on their collaboration; “We enjoy working with Trützschler and applying their technology in VORTEX plants. We’re already operating more than 200 spinning machines with IDF+1 pass. From the first stage of the trial, it was interesting to see that the yarn cut level in IDF+1 pass is less than in the conventional three passage process. This improves spinning machine efficiency a lot. The yarn data shows some small differences between one pass and three passes, but it is difficult to see the difference in knitted fabric. Our target is now to focus on intimate blends. We believe the T-Blend system, IDF and one finisher from Trützschler are a great fit for our sustainable and smart VORTEX factory!”
