From the Sector

Freudenberg Performance Materials (Freudenberg) is extending its recently-introduced ECO range of sustainable nonwoven carpet backings: Lutradur ECO-R and Colback ECO-R backings contain high percentages of recycled raw materials. With its ECO portfolio Freudenberg supports carpet manufacturers in their transition towards an increasingly sustainable product offering.

The company launched its ECO range for sustainable primary backings earlier this year with the introduction of the ECO-RE resource-efficient backings that use less raw materials and support end product recyclability. To achieve this, Freudenberg R&D teams further developed the company’s proprietary yarn production technology allowing for extremely thin filaments.

ECO-R products
Freudenberg’s spunbond nonwoven primary and secondary carpet backings contribute to manufacturers’ easy and efficient production processes as well as to high-performance end products. The company is now extending its ECO range in Europe with Colback ECO-R and Lutradur ECO-R backings that contain a recycled content of between 51 and 90%. Replacing virgin raw materials with recycled polyester saves on natural resources and improves the carbon footprint of end products. The ECO-R backings are specifically suitable for carpet tiles, broadloom, dust control mats and automotive option mats.

The acoustic performance of components for the vehicle interior such as inner dashes or carpets depends on the noise-reducing quality as well as the geometrical adaptability and fill power of their material. With Flexi-Loft, Autoneum offers a new felt-based technology that thanks to a unique blend of recycled cotton and functional fibers reduces product weight and allows for accurate adaptation even to complex shapes. The textile material therefore provides a versatile and more sustainable alternative to foam.

In order to achieve high acoustic performance at minimum weight and maximum sustainability, Autoneum is continuously advancing its textile product portfolio. When it comes to components for the vehicle interior, for example, standard thermoplastic felts excel through their acoustic absorption, robustness and environmental friendliness. However, since felt-based materials are generally less voluminous and moldable as foam components, they require more weight to thoroughly fill the areas of varying thickness between the surface of the component and the vehicle’s body-in-white. In contrast, Autoneum’s Flexi-Loft technology is significantly lighter, more flexible and more adaptable than standard felts. In addition, the fiber-based material is versatile and clearly outperforms current foam products in terms of sustainability.

Thanks to its blend of recycled cotton and polyester fibers, Flexi-Loft substantially reduces component weight while improving geometrical adaptability and acoustic performance, especially in areas of low thickness. Thanks to the specific properties of the fibers, Flexi-Loft enables a precise adaptation to a wide variety of vehicle bodies, thereby improving the noise-insulating qualities of the respective product. Even at low weight, Flexi-Loft covers a wide range of material thicknesses, thus proving to be an ideal decoupling material for interior components with complex shapes such as inner dashes and automotive carpets. As a lightweight, flexible and sustainable alternative to both standard felts and foam, Flexi-Loft distinguishes itself by its versatile application in combination with existing Autoneum technologies such as Hybrid-Acoustics and Prime-Light. Moreover, the material helps to reduce odor and dust inside the vehicle.

Flexi-Loft consists of at least 50% recycled cotton fibers, and cut-offs generated during the manufacturing process are reclaimed, processed and then reused in the production of new felt blanks.

Autoneum is already using Flexi-Loft worldwide as an insulator for various carpets, inner dashes and other acoustic components based on its Prime-Light technology. The application of the material as an effective decoupler in inner dashes made of Hybrid-Acoustics will be launched on the European market in 2023.

• Create truly unique yarn designs: with up to 6 colors from a large predefined color range and infinite combinations of twisting & air entanglement
• Endlessly recyclable yarn solution - available in both standard PA6 and 75% recycled content EqoCycle PA6 yarn
• Efficient and flexible - all colors in stock to shorten lead-time; customized lot sizes

B.I.G. Yarns brings inspirational design freedom to high-end loop-pile contract and automotive carpets with the unveiling of ColorMind. The innovative yarn technology is B.I.G. Yarns’ first venture into a two steps yarn collection, offering a unique solution for creating multi-color PA6 yarns for any carpet design.

Available from mid-June 2021 in both standard and EqoCycle 75% recycled content yarn, designers are invited to work closely with B.I.G. Yarns experts to realize the designs they have always wanted. Combinations of variable levels of twisting and air entanglement, using up to 6 colors at once, elevate design possibilities beyond current limitations.

The ColorMind color bank features predefined colors, always in stock, meaning short lead times. Manufacturers can also benefit from customized lot sizes and bobbin length, creating even more flexibility and design freedom. To preview a taster of the potential directions opened up for loop-pile carpets, B.I.G. Yarns has used the technology to achieve its own “Optica” dot effect and “Illusion” wave effect as inspiration for customers’ design explorations.

“ColorMind offers never-seen yarn diversity to support a new level of design sophistication in high-end carpet segments. We’re very proud and excited to enter into two steps yarns with a solution offering something truly special, the result of intensive dedication from our design and development teams,” comments Emmanuel Colchen, General Manager, B.I.G. Yarns. “ColorMind combines our strengths in delivering high-performance, more sustainable yarns to fit the evolving demands of these segments, underpinned by our expertise in color sequencing and color mixing. We’re looking forward to exciting collaborations and innovative, eye-catching designs for future loop-pile carpets.”

ColorMind PA6 yarns are based on a unique Solution Dyed Nylon yarn and are suitable for Class 33 certification (heavy commercial use). The EqoCycle yarn version is mainly based on post-industrial waste and supports contract and automotive carpet manufacturers with a drop-in circular solution to reduce the ecological footprint of their end carpets.
