From the Sector

Reinach, Switzerland  - Archroma, a global leader in color and specialty chemicals towards sustainable solutions, recently launched at the ITMA exhibition its new Foron® SP-WF, a range of high wet-fast disperse dyes for sportswear and active wear applications.

The Foron® SP-WF dyes are especially suited for the coloration of polyester fibers and microfibers, and polyester/elastane blends, in exhaustion application.
The Foron® SP-WF dyes were developed in compliance with “The Archroma Way: safe, efficient, enhanced, it’s our nature”. The approach finds its origin in Archroma’s deep belief that it is possible to make the textile industry sustainable, economically and ecologically.

The new product is at the core of Archroma's Fast Sport, a coloration system for polyester knitted sportswear, providing the best fastness in the shortest possible time with a reduced environmental footprint.
The Foron® SP-WF range which includes primary and ternary color grades has been developed to fulfil the high color wet fastness and performance requirements of sportswear manufacturers and brands.
Moreover, the core ternary color grades enable deep shades at lower dyeing temperatures on sensitive polyester/elastane fabrics without causing excessive fiber damage, saving energy resources and meeting the high fastness demand of leading brand companies.

When using Foron® SP-WF dyes as part of the Fast Sport system, manufacturers can in many cases have the potential to significantly reduce their consumption of time, energy, chemical, and water, as well as their CO2 emissions.

“We see a growing demand for apparel in the sportswear and active wear segment, reinforced with the now installed athleisure trend,” says Mark Dohmen, Head of Archroma’s Competence Center Automotive and Synthetic Dyes. “Consumers want deep color that stays put on the fiber and brands are defining their requirements accordingly. With our Foron® SP-WF, we can offer to manufacturers of sportswear textiles a solution that combines high levels of wet fastness with high productivity and low resource consumption. Because it’s our nature!”

• A unique partnership enabled Lectra to test its revolutionary laser-cutting technology in a real production environment while delivering sustainable competitive advantage to the world’s leading supplier of airbag cushions.

Reaching the next level of growth and performance
Global Safety Textiles (GST) is the leading independent producer of airbag fabric and airbag cushions and supplier to the majority of airbag manufacturers.
Recognized for its long tradition of research and development, GST uses stateof- the-art technology to manufacture technical textiles for a variety of passive safety applications.
With operations on four continents, the German group has a workforce of more than 5,000.
The company’s worldwide operations and resources enable it to fulfill high volumes of orders promptly, providing the global automotive industry with a steady supply of airbag fabrics and cushions.To address GST’s main business challenges and meet their demanding manufacturing specifications, the group evaluated the performance of FocusQuantum OPW for one-piece-woven (OPW) airbag fabric together with Lectra in the pre-launch phase of the advanced laser airbag cutting solution. Following successful testing of Lectra’s advanced airbag cutting technology in a real production environment in Poland, the group then decided to acquire FocusQuantum OPW for implementation in China.

A one-off join testing collaboration on customer premise
The result of a mutually beneficial collaboration between Lectra and its longstanding customer, specifications for laser OPW airbag cutting solution FocusQuantum took into account GST’s exacting requirements. Once the development of FocusQuantum OPW was completed, both companies agreed to conduct joint
testing. “We came to the idea of joint testing when we visited Lectra’s R&D center in Bordeaux,” says Uwe Zimmermann, COO, GST.
“We discussed taking validation of our specifications to the next level. The idea came up to do it directly in a manufacturing environment.”
The extensive testing enabled GST’s experts to certify FocusQuantum as a proven technological platform for the mass production of airbags. “Process capability was a formal part of validations at GST Poland,” recalls Piotr Siwek. Manufacturing Engineering Manager. “It was verified and confirmed that FocusQuantum meets GST’s targets. The biggest improvement over the previous solution was the software, which we also helped Lectra develop. FocusQuantum Suite is one of the biggest advantages.”

Worldwide standartisation and rollout in China
As a result of the successful joint testing, GST decided to proceed with implementation in China. “Because GST aims to become a major player in Asia,
implementation of FocusQuantum in China is the next logical step for us,” explains Zimmermann. “Standardization of all our equipment worldwide is mandatory for us. That’s why we decided to work with a global player like Lectra.” With more than twice the productivity of the previous solution, FocusQuantum
has exceeded GST’s performance targets. The significantly higher level of process capability has both improved cutting quality and reduced the number
of defective cut parts.
“When we compare the unit output and unit cutting cost, we see a real improvement over the previous generation, so we are quite satisfied with the machine,” notes Sky Yang, General Manager, GST China. “It’s more reliable and productivity is significantly higher.”

Bobingen - On the 4th October 2017 a new brand was introduced at Trevira: Trevira SINFINECO®. This label may be carried by all textiles that contain sustainable Trevira products. Sustainable, innovative, high-value and responsible – these are the values the new brand stands for.

As an industrial enterprise, Trevira is conscious of its special responsibility for an intact environment and has long advocated the recycling of valuable raw materials and waste products. Trevira CEO Klaus Holz: “We at Trevira wish to preserve the environment and at the same time work to create value. These are the criteria of our sustainability concept.“

Creation of the new brand is therefore only a logical step, one that enables customers to label their sustainable Trevira products as such. Trevira is known for the high quality of its products. In every way recycled products are as good as the original materials in terms of quality and performance.

Two vital elements in Pre-Consumer Recycling and an important concept in Post-Consumer Recycling form part of the sustainability strategy of Trevira to conserve resources and maintain value. :

In the area of Pre-Consumer Recycling, on the one hand, residual materials resulting from the manufacture of polyester fibres and filaments in Bobingen and Guben, dependent on the manufacturing step, are processed in the agglomeration plant and restored to become serviceable primary material. The recyclates are then fed back to our fibre and filament spinning mills, to be made into new top-quality products.

On the other hand, in fibre production there occurs in the manufacture of tow a small proportion of tow that cannot be used for converting and has to be cut out. Instead of selling this material as waste, it is cut up, pressed into balls and then carded / combed by a partner, resulting in a 1A quality product. The GRS certification (Global Recycled Standard) is requested for this. As with converter tow from new material, the recycled tow is mostly incorporated into polyester wool blends (55 % PET / 45 % wool), which are used primarily in corporate wear and uniforms.

In the area of Post-Consumer Recycling, Trevira offers filament yarns consisting of 100 % recycled PET bottles. Our parent company Indorama manufactures very high quality recycled chips from PET bottles. Since only transparent PET bottles are used in Thailand, the flakes and chips are of a particularly good and very uniform quality. The recycled chips, fibres and filaments from Indorama bear the GRS certificates (Global Recycled Standard) and RCS-NL (Recycled Claim Standard). Trevira processes the regranulate made by Indorama from bottle flakes into filament yarns consisting 100 % of recycled material. The filament yarns are available in titres 167 and 76 dtex normal polyester. Alongside technical applications, they are used in the automotive and apparel sectors. In addition, many promising developments with the recycled material are on their way.
