3T and ITA show at ITMA how to markedly reduce energy consumption

The 3T TextilTechnologieTransfer (3T) GmbH, Aachen, Germany, and the Institut für Textiltechnik (ITA) of RWTH Aachen University, Germany, present their service offer and support their customers to reach a higher profitability for their processes and machines. Many exhibits and topics of the sections mobility, building & living, health, energy & environment, information & communication, production, materials and qualification and the following test benches underline this expertise: The test bench for the analysis of magnetic weft insertion reduces energy consumption by 60 %. The test bench for energy efficient fibre transport saves 20 – 30 % in energy in industrial processes.

Bild 1_Magnetisches Projektil beim Transport über die Webbreite_Quelle ITAWith the test bench of magnetic weft insertion 3T and ITA present a technology which is an attractive alternative to projectile, rapier and air jet weaving. Through the developed method a weft yarn is transported by a clamping device which is actively led through the shed. Hence any yarn material can be processed. The method’s productivity is similar to air jet weaving. The novel insertion method combines the advantages of existing insertion methods. It combines the productivity of air jet weaving with the versatility of rapier insertion. By avoiding the compression of air the energy consumption of projectile weaving can be obtained. Thus savings of energy costs by 60 % compared to air jet weaving are achieved.

The novel method can be valuable to weaving companies, manufacturers of weaving machines and their suppliers.Bild 2_ITA-Doktorand Christian Möbitz prüft den Fasertransport per Tablet-PC_Quelle ITA Weaving companies can process any yarn material at the productivity that they are used to. The technology shall be ready-to-use in weaving machines by 2019.

Test bench for the optical measurement of fibre transport systems: In spinning mills and nonwoven productions fibres are usually transported by airflow. The transport ventilation is often too large. The new integrated measuring system developed by ITA recognises position and velocity of the fibre flocks in the transport channel. The integrated signal processing adjusts the ventilator of the transported air so that the fibre flocks start to float.  Due to optimised programming the floating starts after two to three minutes (prior after approx. 15 minutes). In industrial processes, 20 – 30 % energy savings are possible. At present the system is adapted for industrial applications. A market entry is planned for the end of 2017. As part of the BMBF-project SozioTex, ITA distributes a questionnaire to the test bench in order to examine how assistant systems like a tablet PC help the   user to reach the required points of process during operation more quickly.

All and more can be witnessed by visiting Hall 8 Booth A113 – A114a
