From the Sector

To expand its support for high-end and luxurious automotive interiors, B.I.G. Yarns has completed its first industrial production runs of virgin polyester BCF yarns for automotive carpet to complement its line of polyamide PA6 superior yarns.

There is a growing market in PET for automotive interior applications, with polyester allowing automotive OEMs and Tier 1 to develop products that, from the outset, consider eco-design by building MONO-polymer carpets and flooring that are 100% recyclable at End of Life (EOL ). These materials are helping to ensure improved and more sustainable EOL recycling of electric vehicles that are driving the future of the car industry.

The new PET BCF Yarns offer high-performance for automotive carpets, including abrasion and stain resistance, and durability, passing all stringent automotive tests including the Taber test for abrasion performance, compressibility and recovery ability test, light fastness in automotive (DIN EN ISO 105-B06) and VOC (fogging) according the VDA 278 test on VOC and FOG emission. The yarns can be color solution dyed, have a dTex between 1300 – 1500, 81 filaments and are ideally for mats with a composition of 400 to 800 gram per m², while the yarns for molded carpets have a dTex of 1200, 144 filaments for 380 gram per m².

With the addition of PET BCF yarns, B.I.G. Yarns is now a one-stop-shop for 3 types of Solution Dyed BCF carpet yarns for the automotive industry: nylon (PA6), polypropylene (PP) and polyester (PET), and the Eqo-range of PA6 yarns – the sustainability focused EqoBalance, EqoCycle and EqoYarn.

The automotive carpet market is expected to grow strongly in the coming decade with the increased demand for vehicle customization and personalization driven by owners looking to upgrade and enhance interiors, including the flooring area.
A growing awareness around car hygiene is also boosting the market as consumers become more conscious of maintaining cleanliness in their vehicles, including the floors. Automotive carpets provide an effective solution by trapping dirt and preventing it from spreading to other areas.

The Oerlikon Manmade Fibers segment will be presenting itself at the Egy Stitch & Tex 2020 between March 5 and 8, 2020 in Cairo – with a clear focus on the needs of the African market. In Hall 1, Stand B2 The Oerlikon Barmag and Oerlikon Neumag experts will also be showcasing the comprehensive product and service portfolio of the world market leader for manmade fiber systems at the stand of Oerlikon’s representative ATAG Export & Import.

The spotlight of the Oerlikon Manmade Fibers segment’s trade fair attendance will be on two core technologies: the new generation of Oerlikon Barmag eAFK Evo texturing machines is to be unveiled within the African market for the very first time. It promises higher speeds and productivity with consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. In particular, the numerous value-added features include two that convince with cutting-edge technology: the optimized, innovative EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

The second technology focus offers new opportunities for the Egyptian market and the Middle Eastern markets in particular: with Oerlikon Neumag’s BCF S8 monocolor and tricolor system, the segment will be unveiling its new carpet yarn production flagship. Superlative spinning speeds, up to 700 individual filaments, finer titers of up to 2.5 dpf – the performance data and technological finesse of the new system have already made a huge impression at numerous trade fairs and roadshows over the past year. The tricolor’s core component is the new, patent-pending Color Pop Compacting unit (CPC-T) for even more flexible and more even color separation. With the CPC-T, individually-controllable air pressures for each color provide pre-tangling, which accentuates the colors and hence makes more than 200,000 different shades possible. Whereas it has been very difficult to manufacture strongly color-separated or color-accentuated BCF yarns from polyamide 6 to date, this will in future be possible thanks to the CPC-T system. As a result of the new design, the CPC-T is now also suitable for processes with low yarn tensions.
 
Expanded product offering for manufacturing carpet yarns
Know-how covering all relevant technologies deployed in manmade fiber spinning plants enables Oerlikon – as the world’s only manufacturer – to expand its range of products and services for making carpet yarns. The POY- and texturing-based system concept is designed for a carpet and home textiles segment that demands particularly soft and bulky polyester yarns with BCF-like properties. Here, the aim is to produce yarns with titers of max. 1300dtex and typically more than 1,000 filaments, with typical products including, for example, 1300dtex f1152, 660dtex f1152 and 990dtex f768. The machine concept comprises the well-known WINGS HD POY winder, along with the eAFK Big-V texturing machine.

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

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."
