• 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.

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.

• The Green Revolution: How Microfactories Can Change the Face of Fashion by Mark Sollman, Product Manager EMEA, Mimaki Europe

With the all-important COP26 Climate Change Conference having taken centre stage in November, there is no time like the present for the fashion world to rally together in stepping up sustainability efforts and getting carbon emissions under control. Globally, the fashion industry is now estimated to account for around 10 percent of greenhouse gas emissions and 20 percent of wastewater , making the pursuit of greener production methods more pertinent than ever before. Thankfully, we are seeing a new era of production enter the fashion arena, with the increasing emergence of technologically advanced, highly automated microfactories.

Along with reducing unnecessary waste through on-demand production, microfactories have a smaller ecological footprint than traditional garment production and require no water use during the production process, making it not only a faster solution, but a greener one too.

Last year’s FESPA saw Mimaki team up with fashion designer Carolina Guzman to bring her designs to life in real time at the show, setting up its own working microfactory live on-site to take her designs from screen to garment within just a day. Guzman’s designs were created using Mimaki’s TS100-1600 Sublimation Printer, before being transferred to textile, digitally cut and finally pieced together. Devised with a string of ethical and environmental objectives threaded throughout, the microfactory also exclusively utilised eco-friendly Greentex fabric, and any remaining material was donated to Sheltersuit: a wind- and waterproof coat that can be transformed into a sleeping bag, which is provided free of charge to homeless people and refugees.

Through working with a number of strategic partners – including transfer printing expert, Klieverik; paper solutions specialist, Neenah Coldenhove; and digital cutting equipment provider, Summa – Mimaki was able to produce a collection of unique, high-quality garments live on the stand during the tradeshow, demonstrating to visitors from more than 100 countries some of the key reasons that microfactories seem set to change the future of fashion…

Unparalleled speed and versatility
Where traditionally, apparel manufacturing has centred on a production chain model of sourcing materials and producing garments in bulk, microfactories are now enabling on-demand, on-location production, making it possible to create everything from unique, one-off pieces and samples right through to entire product lines – all at unprecedented speeds. This means greater flexibility and customisation, enabling designers to modify or update designs and respond to market trends as they occur.

Simplified supply chains and minimised risk
The microfactory setup brings production in-house and on-demand, minimising the cost of not only storing stock, but also of shipping it and responsibly disposing of unsold items. Where recent geopolitical events have highlighted the fragility of global supply chains, microfactories offer a unique independence from these systems, empowering garment manufacturers to future-proof their businesses, become less reliant on external systems and suppliers, and reduce the risk of disruptions.

A boosted bottom line and a greener future
Facilitating savings in a whole line of resources, from physical storage and production space to time and energy, microfactories ultimately have the potential to significantly increase profitability for garment manufacturers, with the additional benefit of being easily scalable as production increases. Perhaps even more compelling, however, are the environmental considerations. Demonstrated on a small scale through Mimaki’s recent project, the environmental benefits inherent to microfactory production will have an even greater impact as it becomes more prolific and commonplace throughout the fashion world, with the potential to effect meaningful environmental change as adoption increases in the years to come.
