Oerlikon Barmag adapted WINGS HD to accommodate growing demand and streamline manufacturing. The company has been providing the idea for high-end home textile applications utilizing the POY and DTY process since 2018. The production of high-quality, high-titer yarns is possible with the help of a spinning concept that combines the WINGS HD winding unit and an automated eAFK Big V Multispindle texturing machine.
In response, we improved WINGS HD to better connect these specialty yarns’ additional requirements to the spinning process and make daily production even more straightforward for our clients, said Stephan Faulstich, POY Process Technology Manager at Oerlikon Barmag.
While the parking periods are much longer while winding high-titers, Oerlikon Barmag has enhanced them in the case of the new WINGS HD versions by up to three times. For example, the parking time for a 300d/384f yarn has been extended from the regular 6.5 minutes to 15.7 minutes, and for a 400d/192f yarn, it has been increased from 4.3 minutes to 10.3 minutes to achieve this. This evens out the doffing process, which raises doffing dependability.
The drawing unit has also been given a more adaptable design, making two-godet operation viable even with yarns that have low overall titers. The energy usage of the winding unit benefits from this.
With WINGS HD 1800, 12 POY packages of up to 600d/576f (final) are created during the spinning process. This is made feasible by an extra godet, which ensures that any high yarn tensions that occur throughout the process are decreased to those typical in winding processes up to this point.
The newly designed suction unit guarantees reliable handling of the yarn with an overall titer of 7,200 dens (final), both during string-up and in the case of a yarn break, in conjunction with the accompanying yarn cutting equipment (yarn collection system).
The concept’s key advantage is that high titers may now be produced directly using the WINGS HD take-up machine, whereas DTY yarns up to 1,200 dens and with up to 784 filaments were previously typically plied from four POY 300d/192f bobbins using DTY machines. Moreover, combining the WINGS HD with the eAFK Big V provides the best option, enabling texturing to use all possible winding locations.
