Oerlikon Barmag: Manufacturing high-titer products using the POY and DTY process optimized

  • Longer parking times for greater efficiency

Since 2018, Oerlikon Barmag has been offering the market’s only currently available concept for high-end home textile applications using the POY and DTY process. The spinning concept with the WINGS HD winding unit in conjunction with an automatic eAFK Big V Multispindle texturing machine manufactures high-titer yarns with maximum machine efficiency.
 
“We have correspondingly modified WINGS HD in order to once again better align the increased requirements of these special yarns to the spinning process and make everyday production even simpler for our customers”, comments Stephan Faulstich, POY Process Technology Manager. The parking times are extremely short when winding high titers. We have increased the parking times by up to three times in the case of the new WINGS HD models. To this end, the parking time for a 300d/384f yarn, for example, has been increased from a standard 6.5 min. to 15.7 min. – and, in the case of a 400d/192f yarn, from 4.3 min. to 10.3 min. This makes the doffing process more even, hence increasing doffing reliability.

This makes the doffing process more even, hence increasing doffing reliability.

At the same time, the draw unit now has a more flexible design, meaning that two-godet operation is also possible in the case of products with low overall titers. This has a positive impact on the winding unit’s energy consumption.

12 POY packages of up to 600d/576f (final) are produced in the spinning process using WINGS HD 1800. This is made possible as a result of an additional godet, which ensures that the high yarn tensions developing in the process are reduced to the yarn tensions common in the case of the winding process to date. At the same time, the newly-developed suction unit with the accompanying yarn cut-ting device (yarn collecting system) ensures – both during string-up and in the event of a yarn break – reliable handling of the yarn with an overall titer of 7,200 den (final).

Whereas DTY yarns up to 1,200 den and with up to 784 filaments have in the past, as standard, been plied from four POY 300d/192f bobbins using DTY machines, high titers can also be manufactured directly using the WINGS HD take-up machine. Combining the WINGS HD and the eAFK Big V allows all available winding positions to be utilized during texturing.

Cost-efficient BCF yarn production for demanding processes with Sytec One from Oerlikon Neumag

Cost-efficient production of carpet yarns beyond commodity products can constitute a challenge. Highly standardized production systems must strike compromises with regard to throughput, quality or cost-efficiency. At the Domotex 2018, the world's largest trade fair for floor coverings, Oerlikon Neumag will present the Sytec One solution for demanding BCF processes.

The Sytec One is a BCF plant with only one end per position. Due to this single-end characteristic, it is particularly well suited for demanding production processes, such as recycled polyester or fine filaments. The reason: In the event of a yarn break, only one end breaks. All the other positions are not affected and continue to run. As a result, this plant has a higher efficiency compared with a multi-end technology plant. For example, with ten breaks a day, the efficiency of the Sytec One is still over 98%, while a threeend technology achieves only 92% efficiency.

Higher productivity due to the straight yarn path

Higher productivity due to the straight yarn path

The machine concept of the Sytec One with its absolutely straight yarn path in spinning and texturing also enables significantly higher process speeds compared to multi-end technologies. This results in a speed increase of up to 15%. In addition to standard processes, more demanding processes with higher break rates play an increasingly important role. "The product mix is critical to the choice of technology," said Martin Rademacher, vice president of sales Oerlikon Neumag. "We are in the comfortable position of being able to offer our customers both a single-end and a three-end technology."
