• 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.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

As a combined effort of the CSI color team and DyStar’s technical experts, DyStar and CSI are launching the first 2 issues of the Sustainable Color and Trend magazine with Cadira® color palettes.

This new magazine inspires Designers and Color Managers by offering palettes and color combinations that are Eco-friendly and Inspired by Nature. Not only does the magazine include a wide range of color palettes, but also color validation in CSI’s Relative Color Popularity (RCP) information as well as sustainable dye recipes that have been formulated based on the Cadira resource optimization process.

The Cadira Concept is a module in DyStar’s Resource Efficiency program. It helps to considerably shorten lead times and reduce water, waste and energy consumption. Cadira Concepts have been developed for different substrates and dyeing procedures. This launch focuses on both reactive dyeing of cotton as well as polyester & recycled polyester dyeing.

The reactive-issue – Inspired by Nature – offers color palettes with softer, muted tones, levels of neutrals and earthy shades of green. The recipes are based on DyStar Levafix® and Remazol® combined with Sera® chemicals for an optimized dyeing and wash-off process.

The Polyester issue offers more vibrant color options with saturated colors and brights for active wear and outdoor clothing and accessories. The recipes are based on Dianix® dyes and the dyeing process can be optimized by use of the Optidye® PES program.

“We are conscious about our environment so we wanted to create a magazine with an ecological color and optimized processes so that our customers can pick the right color that will help them reduce their environmental impact in the design process.” Says Ron Pedemonte, VP of Sales and Marketing Americas.

CSI will fcus more on color palettes with ecological dyes and low impact processes when offering color and trend information to customers in the future. More eco-friendly color palettes will be available very soon.
