Retech to exhibit interesting innovations at ITMA 2019

This would be the third time that Retech would be showcasing at ITMA after its participation in 2011 in Barcelona, and 2015 in Milano. In addition to the three innovations displayed, there would be further new things to be discovered on stand B109 in hall 7.

As an expert in monitoring yarn tension to perfection, Retech will show in Barcelona a further development of the long proven and successful yarn tension sensor. This yarn tension sensor, which is based on HALL sensor technology, has established itself in the last 20 years as the leading technology for the on-line measurement of yarn tension. The main characteristics such as robustness, insensitivity to external influences, high accuracy, long term stability and user-friendly service have led to the Retech yarn tension sensor becoming a ‘must’ in the production of filament yarns. The main range of application is in false-twist texturing production (DTY), but there are other applications such as in extrusion (FDY/BCF), in air jet texturing and in diverse winding processes, where the monitoring of yarn tension is essential for the continuous assurance of yarn quality. At any point technical or commercial boundaries are met, and so it is necessary to offer successful solutions in these technically related areas.

For this reason Retech has developed the proven yarn tension sensor with HALL technology in two directions. In Barcelona, the company will show a version for application in extrusion. A sensor, which is foreseen with additional characteristics, in order to be able to withstand the even greater demands and influences of a spinning process at high speeds (4000 m/min. +) and higher yarn counts (3000 dtex +). The company will also show a low-cost version, which omits a few features.

As an expert in drawing fibres to perfection, Retech will present its second main innovation—a new godet generation for the drawing and treatment of all kinds of synthetic yarns. Based on the proven and efficient motor technology by means of permanent synchron magnet technology, which enables a very economic operation, an interesting further development has taken place, which rounds off further the Retech godet roll range.

Retech sets its stall by the permanent synchron magnet motor technology and offers three product ranges. Based on a motor size of 80, godet rolls with diameters 100-127 mm are offered. The motor size 90 is concentrated on diameters 150-160 mm and the motor size 112 based on diameters 190-250 mm. All three ranges cover different godet roll lengths and heating possibilities (1-6 zones, STS (non-rotating PT100 temperature sensor) or RTS (rotating temperature sensor)) including the necessary measured value transmitter and are consequently designed according to the modular system, which demonstrates interesting economic possibilities for the customer, even with small numbers of units.

In addition to the standard godet rolls (whereby each godet roll is trimmed and optimised for the chosen range of application), Retech will also exhibit godet rolls for washing and drying processes for high performance fibres. Even so there are also godet rolls with external drives, which find application in different niche markets (artificial grass, medical applications, horizontal drawing lines, etc.).

The third part of the special innovations concerns the original Retech product range. Retech, which a short-form of regulation technology, and whose origin springs from temperature regulation, will be showing its newly developed temperature control and measured value transmission line. Under the name ‘Blue-Line’, the next generation of this system will be shown at ITMA Barcelona.

By means of the re-worked Blue-Line, the advantages of the individual systems are now combined and enable new interesting areas of application. (RKS)
