From the Sector

Pulcra Chemicals and Inditex develop Sustineri Coloring, a combined pretreatment and dyeing process for cotton and polyester/cotton resulting in water, time and energy savings. This process is the result of a joint research between Pulcra Chemicals and Inditex with the goal to mitigate the impact of standard dyeing processes and to reduce the use of natural resources.

Sustineri Coloring is based on newly engineered process chemicals which allow a one bath pretreatment and dyeing process for dark, medium and light shades of cotton and polyester/cotton fabrics by exhaust method. This results in shorter processing time and less use of water and energy.

The process is already used by selected mills and it showed that Sustineri Coloring is reducing in pretreatment and dyeing the processing time by up to 60 % and the water and energy consumption by up to 80 and 60% respectively. The state-of-the-art products allow a one bath treatment which is the key in saving resources.

Silence and resource efficiency are the order of the day in the development and optimization of electric vehicles. On the one hand, ever stricter emissions regulations worldwide are increasing demand for components that reduce noise pollution while helping vehicle manufacturers meet their sustainability targets. On the other hand, the absence of noise from the combustion engine in e-cars amplifies the disruptive effects of other noise sources in the passenger compartment. With Ultra-
Silent Tune, Autoneum now presents a new lightweight and environmentally friendly technology for underbody shields that reduces tire rolling noise both outside and inside the vehicle, thus improving not only acoustic performance but also driver comfort in electric cars.

Autoneum's Ultra-Silent Tune technology owes its sound-absorbing performance to acoustic chambers of different shapes and sizes. The chambers are created by applying an embossed polyester foil to the side of the Ultra-Silent underbody shield facing away from the noise source: they capture the sound waves emitted by the car tires, modulate them according to their respective geometry and reflect them back onto the porous carrier material. Compared to conventional single-layer underbody shields, whose acoustic performance is mainly determined by the noise-reducing properties of the product side facing the tires, Ultra-Silent Tune exploits both sides of the component, which significantly improves its acoustic absorption. Autoneum thus makes innovative use of the proven concept of traditional chamber absorbers, reducing exterior tire rolling noise.

Moreover, Ultra-Silent Tune combines optimized acoustic performance with the sustainability benefits of Autoneum's Pure technology Ultra-Silent. In addition to the high proportion of recycled PET fibers, underbody shields made from Ultra-Silent Tune can be manufactured from 100% polyester and thus be fully recycled at the end of vehicle life. Furthermore, the thickness of the multilayer construction can be flexibly adapted to the packaging spaces of different vehicle models. Underbody shields made from Autoneum's new Ultra-Silent Tune technology are already in pre-development at various vehicle manufacturers in Europe.

Spinnova has entered into a yarn development cooperation agreement with the Portuguese company Tearfil, where Tearfil will operate Spinnova’s R&D yarn-spinning line. The yarn-spinning line is intended for product development and will be located in Guimarães, Portugal at Tearfil's facilities.  

The rationale behind the yarn-spinning line is for research and development into using Spinnova's fibre in commercial scale yarn production and to streamline development work with industry partners.   
Spinnova has decided to locate the line in Guimarães in Portugal, at Tearfil’s facilities. Spinnova will benefit from the industry know-how of a strong partner and from the proximity of one of Europe’s most significant textile industry hubs in Portugal. This will improve Spinnova’s access to global textile markets.   

Spinnova’s yarn-spinning line will be installed at Tearfil's premises. The technology delivery and installations are expected to take place in the fall of 2023, and the spinning line is intended to be operational by the end of the year. Tearfil is responsible for the yarn-spinning line's operations, and Spinnova will use a part of the line capacity for its product development.  

In 2021, Spinnova announced that it would establish an R&D yarn-spinning line in Jyväskylä, Finland. The decision to change the location was made during the feasibility planning and discussions with potential partners. This change in location and operational model will slightly decrease the capital expenditure and will lead to lower operational expenses.  

The technology supplier for Spinnova's new spinning mill line is the Swiss-based company Rieter. Rieter is a leading supplier of systems for manufacturing yarn from staple fibers in spinning mills. The company develops and manufactures machinery, systems and components used to convert natural and man-made fibers and their blends into yarns in the most cost-efficient manner.

Fong’s Europe will showcase the advanced features of its THEN Smartflow TSF at ITMA 2023.

These include the machine’s smart fabric transport system which ensures extremely even dyeing of the fabric through accurate control of the nozzle pressure and pump power, with movement through the machine via an PLC-controlled plaiting system and variable chamber adjustment depending on fabric characteristics.

The machine is equipped with a heat exchanger enabling it to heat the dyeing liquor quickly and efficiently, to reduce energy consumption. Its bath preparation unit and chemical dosing system ensure accurate and precise dosing of chemicals, dyestuff and salt, reducing chemical waste and optimising results while reducing process times.

The Smartflow TSF operates with a low liquor ratio of down to 1:2.5 with full loading of synthetic fabrics, which means that it requires less water to dye a given amount of fabric compared to traditional dyeing machines. This not only reduces the consumption of water and steam, but also the amount of wastewater generated.

The machine's control panel is easy to use, allowing operators to programme and monitor processes with ease.

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.

CHT and Fulgar have collaborated to support the goal of reducing the carbon footprint with an effective and sustainable solution for the textile market.

Combining FULGAR’s circular economy ready yarns with CHT’s resource-saving dyeing techniques significantly reduces the usage of natural resources and leads to lower environmental impact and ultimately a lower carbon footprint. The combined process needs less water, uses less energy, and saves time while meeting the color fastness standards for finished textile products.

The combination of 100 % biobased polyamide EVO® by FULGAR yarns with CHT sustainable dyeing application can save water up to 64 %, energy use up to 50 % and process time up to 50 %, when compared to standard dyeing processes. Sustainable dyeing of EVO® is promoted using CHT’s soy-based dyeing auxiliary SARABID TS 300. SARABID TS 300 has accredited a C2C Certified Material Health Certificate at Gold level and USDA Certified Biobased Product Certification.

EVO® by FULGAR, the totally renewable yarn based on castor plants, does not require high amounts of water - 4 times less compared to cotton. In addition to the sustainable aspect, EVO® by FULGAR offers characteristics like lower fiber weight, particular moisture management and higher stretch often without the need for elastomer fiber. This helps to avoid material mixes for better recycling opportunities. EVO® provides greater user comfort, mainly for performance and casual apparel.

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

Lenzing Group, a global producer of wood-based specialty fibers, is celebrating the 40th anniversary of its biorefinery and co-product brand LENZING™ Acetic Acid Biobased. The brand was first introduced on May 4, 1983, and has since become one of the leading and most trusted biobased acetic acid providers.

Over the past 40 years, LENZING™ Acetic Acid Biobased, which has a reduced carbon footprint that is 85% lower than that of fossil-based acetic acid, has continued to gain trust and support from customers. Specialty chemical company Evonik, and food production company Speyer & Grund Group, have been incorporating LENZING™ Acetic Acid Biobased in the production of their products since 1983. LENZING™ Acetic Acid Biobased has also been in high demand from the hygiene industry during the COVID-19 pandemic as an all-purpose cleaning agent in conventional and green products.

Pioneering a carbon neutral future in the biorefinery segment with a new offering
To mark the important occasion, Lenzing will introduce its first carbon neutral LENZING™ Acetic Acid Biobased to meet the growing sustainability needs of industries which predominately rely on fossil-based materials. Similar to the standard LENZING™ Acetic Acid Biobased, the carbon neutral LENZING™ Acetic Acid Biobased is produced using sustainably sourced beech wood as a universal replacement for non-renewable raw materials such as crude oil. By calculating, reducing and offsetting emissions during production processes, this expansion will create a more sustainable supply chain with highly functional products across various industries. From now on, Lenzing customers across the food, pharmaceutical, cosmetics, chemical and textile industries will be able to choose between carbon neutral and reduced carbon footprint acetic acid products.

Advancing circularity and carbon neutrality through efficient use of valuable resources
Lenzing’s biorefinery concept ensures that 100% of wood components are used to produce pulp for Lenzing’s botanic fibers, biorefinery products, as well as bioenergy, which is used to power Lenzing’s facilities. This makes Lenzing’s biorefinery sites almost fully energy self-sufficient to remain as carbon neutral as possible. To ensure a low carbon footprint, rail transportation is the preferred means for transporting LENZING™ biorefinery products, with trucks being leveraged in regions where rail transportation is not available.

Together with ClimatePartner, a recognized global leader in the design, development, and delivery of corporate climate action programs, Lenzing strives to reduce carbon emissions to net-zero through a mix of higher production efficiencies, use of renewable energy sources, low-carbon materials, and the dedicated support of an external nature-based carbon removal project. For instance, to offset remaining carbon emissions that cannot be reduced, Lenzing works with ClimatePartner to support and finance the switch to biomass as an energy source at a ceramic factory in Kitambar in northeastern Brazil. Using natural waste materials, like coconut shells, as renewable biomass for its energy production, the factory is able to produce roof tiles in a more climate-friendly way while saving on carbon emissions. Besides contributing to the fuel switch, the project also helps to reduce the deforestation rate in Brazil and avoid methane emissions that could result from the uncontrolled rotting of biomass.

ERCA, Patagonia® and YKK announce the implementation of ERCA’s REVECOL®, a sustainable, innovative chemical agent, in YKK’s dyeing processes at their Vietnam production sites transforms common waste material, such as exhausted vegetable cooking oil, into an upcycled, certified high performance, safe textile chemical. ERCA has invested in circular practices to take waste material and use them as feedstocks to create new responsible chemical products.

Always searching for new sustainable innovations, REVECOL® caught the attention of Patagonia®. Driven by the goal to utilize non-extractive chemistry in their supply chain wherever possible, the brand teamed up with ERCA and trim supplier YKK to deploy REVECOL®.

REVECOL® LV-TS has a carbon footprint that is 72% lower* than the more conventional chemical auxiliaries produced by ERCA. Today ERCA produces a wide range of high-performance chemical auxiliaries made from used vegetable oil that are ZDHC, bluesign® approved and GRS certified.

ERCA is one of the first companies to have GRS certified chemical products, opening the door to circular chemical auxiliaries.

As part of their Sustainability Vision 2050, YKK is constantly working to deploy more sustainable chemical processes in their production.
