From the Sector

Trevira CS is exhibiting for the first time at CSI Miami (Cruise Ship Interiors Design Expo Americas). Taking place on 6 – 7 June, 2023 at the Miami Beach Convention Center, CSI will bring together buyers and suppliers involved in cruise ship interiors, including interior designers, architects, outfitters, shipyards and suppliers.
 
On the Trevira CS stand, visitors can get an idea of the wide range of flame retardant fabrics suitable for use on board cruise ships. 53 fabrics from 20 Trevira CS customers will be on display that either have IMO certification and/or have been tested to the fire safety standards (FTP Code) required in the marine sector. Trevira CS fabrics are inherently flame retardant, meaning that their flame retardant properties cannot be washed out or lost through aging or use. This is due to the chemical structure of the polyester fiber: the flame retardant properties are firmly anchored in the fiber and cannot be altered by external influences. A surface-applied flame retardant finish is therefore not necessary.

In the marine sector, the demands placed on textiles are not only high in terms of fire protection, but also with regards to light resistance and durability. This is particularly true for textiles used in outdoor applications. These must be extremely robust, as they are exposed to moisture and sunlight. To meet these requirements, Trevira CS has launched a range of 30 new spun-dyed, UV-stable filament yarns. Besides color depth and durability, spun-dyed yarns offer another advantage: They are more sustainable because the fabrics made from them can be produced in a more environmentally friendly way than textiles that are dyed in one piece or consist of brightly colored yarns. In fabric production, a large share of resource consumption goes to the dyeing and finishing of fabrics as well as the use of chemicals and water. However, with spun-dyed yarns, these processing steps are unnecessary – the yarn immediately comes out of the spinneret in the desired color, reducing the products’ environmental impact.

The topic of sustainability is also taken up in other Trevira CS products. For example, Trevira CS fabrics are available in recycled versions. They consist of fiber and filament yarns obtained in different recycling processes. Filament yarns are produced using recycled PET bottles, they contain 50% post-consumer recycled material. Recycled fibers are obtained using an agglomeration plant and in further processing steps from residual pre-consumer waste from production. They consist of 100% recycled material (pre-consumer recycling). All flame retardant recycled Trevira® products are GRS (Global Recycled Standard) certified.
Fabrics made from these yarns are marked with the Trevira CS eco trademark. The prerequisite for this is a recycled content of at least 50%. Among the fabrics presented at the Trevira CS trade fair stand are 8 fabrics bearing the Trevira CS eco brand.

The long-term goal in developing sustainable products is undoubtedly to enter a circular economy. For this new path, an innovative Trevira CS product development was launched, producing flame retardant fibers and filament yarns from chemically recycled raw material. In this case, the basic raw material for the chemical recycling was PET bottles, but essentially it could be most any other PET recyclables, such as packaging material or even textiles. Chemical recycling involves depolymerization, a sequence of chemical reactions in which the polymer chains are broken down again into their original components, i. e. the monomers. In a further processing step, impurities are removed. Before the polymerization process is initiated, a small amount of MEG (mono ethylene glycol) is added.

The same technology used to produce the original (virgin) raw material for Trevira CS is also used here. The flame retardant modification is added during polymerization. In this way, the flame retardant properties are indelibly anchored in the polymer.

By recycling valuable materials such as packaging material, waste can be avoided. The raw material obtained from the recycling process is comparable to the original material can be used again in high-quality products.

PIAVE MAITEX, recognized as a preferred partner for the global textile industry, brings on the successful path of responsible and smart innovation and presents its unique line “AGAIN”, during the MarediModa fair in Cannes.

During the Functional Fabric Fair, the trade-exclusive event where the latest trends in fabric development for the functional textile industry are showcased, PIAVE MAITEX presents AGAIN a smart and technically advanced line, that balances performances, functionality and sustainable features, formed of highly performing jerseys. Two premium Global Recycled Standard (GRS) certified sustainable ingredients have been involved in the production of AGAIN: the premium stretch fiber ROICA™ EF – part of ROICA Eco-Smart™ Family – constructed out with more than 50% pre-consumer recycled content and perPETual high quality sustainable polyester born from a cost-effective process that reverses engineer consumer waste PET bottles.

In addition to the two key high-tech, responsible and GRS certified raw materials, the Italian manufacturer will present a new development characterized by sustainable water-saving printing, with the possibility to be color-customized. Moreover PIAVE MAITEX will showcase the unique and innovative combination of two AGAIN articles to obtain an entirely sustainable bonded fabric with the possibility of personalized colour combinations. The range of functional fabrics, dyeable and transfer printable, perfectly combines creativity, innovation, real performance and sustainability all at once offering unparalleled comfort, performance, and tenacity.

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.
