• Huntsman Textile effects redefines dyeing of polyester including microfiber and blends with UNIVADINE® E3-3D diffusion accelerant
• Eco-friendly diffusion accelerant provides reproducible, high-speed polyester dyeing

Singapore – Huntsman Textile Effects introduces UNIVADINE® E3-3D next-generation diffusion accelerant to help mills achieve high-performance dyeing of polyester, microfibers and blends in an environment-friendly way that complies with current and anticipated industry sustainability standards.

The demand for polyester and man-made fibers is booming as sports and athleisure apparel markets expand rapidly around the world. At the same time, big-name brands that set trends in the sector continue to increase focus on sustainability and performance. As such, this is putting pressure on mills since the current industry standard involves chemically active diffusion accelerants that contain unwanted chemicals and require additional leveling agents and anti-foaming products that may be hazardous to people and the environment.

Developed by Huntsman Textile Effects specifically to meet these challenges, UNIVADINE® E3-3D diffusion accelerant is low-odor, free of benzyl benzoate and other hazardous substances. Part of Huntsman’s range of innovative dyEvolution™ dyeing auxiliaries, it uses Huntsman’s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties.

“UNIVADINE® E3-3D diffusion accelerant delivers across three key dimensions – diffusion, leveling and migration – for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio,” said Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects. “We expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.”

UNIVADINE® E3-3D diffusion accelerant has a high affinity to polyester, causing the fiber to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple leveling mechanisms then slow down the exhaustion rate to ensure safe, defect-free dyeing. Finally, as the dye bath heats up, the product’s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.

As a result of this cutting-edge diffusion technology, UNIVADINE® E3-3D diffusion accelerant can be used to successfully dye polyester fibers in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products. Reducing exposure to high heat, its Active Diffusion Technology minimizes the potential to damage the elastane in polyester-elastane blends and provides for on-tone dyeing of microfibers. The superior migration support of UNIVADINE® E3-3D diffusion accelerant also increases reproducibility, allowing mills to dispense with additional leveling agents. Polyester, microfibers and blends treated with UNIVADINE® E3-3D diffusion accelerant comply with the requirements of bluesign®, in addition to being suitable for Standard 100 by OEKO-TEX® and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products*.

With an investment in an Innovation Center with testing labs and additional production facilities, Carl Meiser GmbH&Co KG gives a clear statement to it’s location in Albstadt in Central Europe. As well this underlines the know-how and the motivation of the whole team. The constructions were already launched. The first buildings for production and a part if the Innovation Center will be ready end of this year. State of the art offices and social facilities will be ready to move in mid of 2019.

“After our suffered setback with the fire in our production facilities in November 2017, this investment will move us much more forward and will give us the motivation to offer our customers even better and more innovative service and products. In long-term view this will creates the base for further growth”, says Jens Meiser CEO of Carl Meiser GmbH&Co.KG. During the last months we already invested in production technology and machines. During the last weeks we changed the complete production organisation to reach a lean product flow.

As well Meiser expanded it’s apprenticeship programme during the last years. At the moment we apprentice new staff members in three different education programmes. It is planned to add a fourth in management in future.

The company Carl Meiser GmbH&Co.KG with it’s brand „MEISER – Know How in textiles“ delivers to the high end underwear and lingerie industry as specialised dyehouse for knitted fabrics. With the brand “NOPMA technical textiles” the company acts as a fast growing development and production partner for the aviation, automotive and furniture industry as well the protection fabric industry. For this industries coated fabrics are developed and delivered to the markets. “In this sector we grow continuous during the last years. We are convinced that our investment in the Innovation Center will support this growth next to our first presence as exhibitor on the fair Techtex in 2019”, says Jens Meiser.

In the approval phase the company was supported by the city of Albstadt in all necessary questions. Fast and possible solutions were found. This shows the Mittelstands-friendly climate in this region in south Germany. The invest is supported by the national programme “Spitze auf dem Land” by the country of Baden-Württemberg and the EU.

OutDoor2018: Schoeller’s coldblack® technology has been specifically optimized for use on knitted and woven fabrics so brands can now expand their product application uses. Under the blazing sun, textiles with coldblack® heat up less and stay cool to the touch. Südwolle Group, a leading manufacturer of high quality yarns, has also recognized the ideal combination of merino and coldblack®. With this, the wear comfort of wool apparel can be tangibly improved.

Wool is well known for its various property benefits, including insulation, natural antibacterial protection, odor control, light weight and nearly wrinkle free composition. Not only in the winter time, but also in summer particularly merino wool, a special high-quality type of wool, regulates moisture balance and thus the body temperature. The fibers can absorb a great deal of moisture or sweat and transport it away from the body. Warm ambient air quickly dries the material and causes a cooling evaporation, which makes it very comfortable to wear merino apparel in the summer time.

coldblack® technology from Schoeller supports the natural properties of wool because it reliably reduces heat build-up when exposed to the sun. Together with the help of Südwolle Group, the finish has been optimized specifically for the use in merino apparel. The yarn manufacturer chooses coldblack® for a variety of uses, especially for knitting and weaving yarns for sports and outdoor apparel and develops such products individually according to its customers’ requirements.

Stéphane Thouvay, Managing Director Product Management & Innovation at Südwolle Group, summarizes the use of the technology as follows: “coldblack® is part of our product range for the summer time, which we will be presenting at OutDoor show in Friedrichshafen. The technology reduces not only heat build-up, but also enhances the natural UV protection of wool without affecting the look and feel of the fabric. Therefore coldblack® perfectly fits into our yarn selection for sports and outdoor apparel, for example in our collection ʻYarn in Motion’. For end consumers garments made of coldblack® yarns can optionally be labeled with hangtags.”

When used in high-quality woolen fabrics, coldblack® has already proven its performance and is being used by renowned brands in various collections of men’s suits. Since 2008, the technology has been licensed by more than 200 brands, in sports particularly in the field of cycling, triathlon and golf. All components of the finish are bluesign® approved.

The market for the production of carpet yarn is increasingly evolving towards more demanding processes. However, beyond commodity products, standard plants can no longer fully exploit their advantages. From 20th to 22nd March 2018, Oerlikon Neumag will be presenting an economical alternative in Shanghai in hall W3, booth F03 at the Domotex asia/Chinafloor, the leading floor covering trade fair in the Asia-Pacific region: the BCF plant Sytec One with single-end technology.

If the requirements for the production of BCF yarns increase, for example, from recycled polyester or fine filaments, then this can also lead to higher breakage rates. Highly standardised production plants must then often strike compromises with regard to throughput, quality or cost-efficiency. In such cases, the Sytec One offers a good solution instead of the mostly three-end technology plants for standard processes.

Single-end technology with 98% productivity

This BCF plant works with only one yarn (end) per position, making it ideal for demanding production processes. The reason: when a yarn break occurs only one yarn tears, all other yarns continue to run. This not only simplifies troubleshooting, it also reduces the re-threading time. In addition, less waste is produced. As a result, the productivity of the Sytec One is still over 98% for ten breakages a day, while a plant with three-end technology only reaches around 92%.

Faster processes due to a straight yarn path

In addition, the absolutely straight yarn path of the Sytec One enables significantly higher process speeds of up to 15% in spinning and texturing processes compared to multi-end technologies. Higher total titers of up to 6,000 dtex can also be produced without any problems. The gentle yarn guidance also ensures minimum friction on the individual filaments. This means less yarn breaks and a more stable process.

Optimised key component: spinning pack

Last but not least, the engineers at Oerlikon Neumag have developed a new design for the spinning pack. This central component of every BCF machine significantly influences the yarn quality. The corresponding solution for the Sytec One optimises the polymer flow in the spin pack, thus reducing the polymer dwell time. This leads to shorter product and colour change times and increases the plant efficiency. In addition, the spinning packs were widened so that yarns with up to 500 filaments can now be produced.

The product mix is decisive

In view of these advantages, the single-end Sytec One is recommended for processes with high breakage rates, fine filaments, frequent colour changes or in general when demanding processes take up an increasing share in the business. "The product mix is decisive for the choice of technology," sums up Alfred Czaplinski, Sales Manager BCF at Oerlikon Neumag. "We are happy to advise on the optimal solution and offer both single-end and three-end plant technologies." 

Good business at the Domotex Hanover, Germany

In the run-up to the trade fair, the Domotex Hanover in mid-January was already proving to be a promising harbinger. With four lively trade fair days and contract conclusions in the lower double-digit million euro range, mainly from the European and Asian markets, the order intake for Oerlikon Neumag was very good.

In Sachen Eigensicherung bei Wintereinsätzen setzt die bayerische Bergwacht künftig auf den Erfinder und Technologieführer von Lawinenairbags ABS. 50 Dienststellen wurden mit rund 250 ABS P.RIDE Original Lawinenairbags ausgestattet. Eine eigens entwickelte Software sichert große Suchmannschaften von bis zu 200 Helfern bei der Gefahr vor Nachlawinen.

Rettungsmannschaften sind während ihrer Einsätze in lawinengefährdeten Gebieten besonders der Gefahr von Nachlawinen ausgesetzt. Speziell für diese Situation mit großen Einsatzgruppen liefert der Lawinenairbag-Hersteller ABS nun ein Sicherheits-Plus. Während das klassische P.RIDE System bis zu 15 Personen im Partnerauslösungs-System erfassen kann, hat der Technologieführer für die Bergwacht Bayern eigens eine Software entwickelt, die es ermöglicht Suchmannschaften von bis zu 200 Helfern zu gruppieren, auch wenn einzelne Helfer zu einem späteren Zeitpunkt am Einsatzort eintreffen. Dank der integrierten Partnerauslösung ist dadurch eine gegenseitige Sicherung zu jeder Zeit gewährleistet.

Die Bergwacht Bayern beginnt mit 250 P.RIDE Einheiten um sukzessive die neue Technologie einzuführen. Zur Partnerschaft mit ABS sagt Paul Schenk: „Die Sicherheit der Retter hat für uns oberste Priorität, mit ABS setzen wir die langjährige Partnerschaft mit einem zukunftsweisenden Lawinen-Airbagsystem fort“.

Laut Studien werden 20 Prozent der Airbags bei einem Lawinenabgang nicht ausgelöst. Mit dem Lawinenairbag P.RIDE vom Marktführer ABS wurde erstmals eine Lösung für dieses generelle Sicherheitsproblem gefunden – durch eine serienmäßige, wechselseitige Partnerauslösung per Funk. Die Funkverbindung zu den Partnern mit P.RIDE Lawinenairbags erlaubt es, im Ernstfall sowohl die eigene Verschüttung, als auch die von Begleitern in einer Gruppe aktiv zu verhindern und alle verbundenen Airbags auszulösen.
