B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

Freudenberg Performance Materials (Freudenberg) announces the launch of sustainable carpet backing products for the flooring industry. Sustainable backings support customers in their transition towards producing more sustainable carpets. The range is introduced as Colback ECO and Lutradur ECO and is part of the Freudenberg portfolio of high-performance spunbond nonwoven technical textiles.

Reduced CO₂ footprint
Freudenberg follows a ‘less is more’ principle: the best raw materials are the materials that are not needed at all. For the ECO product range, Freudenberg R&D teams developed a solution to save raw materials in their carpet backings. Freudenberg redefined its proprietary yarn production technology allowing for extremely thin filaments with a diameter up to 30% smaller than the standard portfolio for carpet backings.  
The new thin yarn technology is one of Freudenberg’s sustainable initiatives benefitting the carpet industry. Other developments supporting sustainability include backings with a high recycled content and backings using alternative approaches to facilitate carpet recyclability. They will extend the ECO portfolio in the future.

ECO-CHECK-Label
The currently launched thin yarn ECO-backings have been awarded the ECO-CHECK label. Freudenberg introduced this label in early 2021 to identify particularly sustainable products within its portfolio.

Carbios announces the publication of an article entitled “Enzymes’ power for plastics degradation” in Chemical Reviews.

The Woolmark Company, the Italian wool fabric mill Vitale Barberis Canonico (VBC) and Haelixa took part in a trial to trace Australian wool fibers up to the final fabric.

Funded by Australian woolgrowers, The Woolmark Company (TWC) is an enterprise that focuses on investments that enhance the profitability, international competitiveness, and sustainability of Australian wool. In their operations, TWC seeks to be transparent and accountable. In line with this strategy, traceability is necessary to ensure transparency and maintain the credibility of TWC.

In December 2021, Haelixa marked wool fibers with their DNA tracing solution. There are infinite DNA markers that could be produced and used to indicate a specific origin, supply chain, material, or particular collection. In this case, a single DNA has been applied to greasy wool and a second DNA marker to scoured wool. The first DNA identifies the origin of the Australian wool, while the second determines the manufacturer where the wool has been further processed; at Vitale Barberis Canonico mill.

Samples were collected from various production stages, where a qPCR test was used to detect each specific DNA marker. Haelixa uses a “Key-Lock” system to detect a marker; one needs to know the particular DNA to screen for, ensuring that the system is tamper-proof. The DNA markers stay safely embedded in the product, enabling traceability of greasy and scoured wool up to greige fabric and finished fabric, respectively.

With increasing cost pressure and competition in the wool fabric market, traceability is becoming a prerequisite to proving authenticity and origin. TWC and Vitale Barberis Canonico support the culture of sustainability and collaboration.
