From the Sector

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

B&B Italia unveiled a special edition Camaleonda, the iconic sofa system by Mario Bellini, adorned in a brand-new fabric designed by Stella McCartney – platforming her S-Wave monogram. Marking the second chapter of the partnership between the British conscious luxury pioneer and the Italian design house, the collaboration was launched at Art Basel Miami Beach on 6th December 2023 as part of an installation at B&B Italia Design Studio’s grand opening. The Camaleonda is crafted from nearly entirely sustainable materials, materialising both brands’ nature-positive visions.

The partnership between B&B Italia and Stella McCartney was born of Stella’s long-time personal passion for Bellini’s works and started in 2022 with the Le Bambole armchair. It evolves now with the new version of Camaleonda, the sofa system originally designed in 1970, which made its comeback 50 years later in 2020 - speaking a contemporary language between structural solutions and sustainable choices.

The brand-new Stella McCartney X B&B Italia Camaleonda introduces the latest printed fabric “S-Wave”, which is the result of a next-generation sustainability innovation introduced by the design company’s R&D team. The S-Wave upholstery, available in two different colours, is based on OceanSafe naNea yarn, which is verified to be biodegradable, Cradle to Cradle Certified® Gold and does not contain harmful substances. The material does not shed persistent microplastics into the environment, however, performs like conventional materials.

Hologenix has announced that its flagship product CELLIANT® infrared (IR) technology, a natural blend of IR-generating bioceramic minerals, is now more widely available from the company as a printed coating, expanding the uses of the technology and increasing the number of prospective partners. The innovation has already been named a Selection in the Fibers & Insulations Category of the ISPO Textrends Awards just last month.

Traditionally, CELLIANT has been embedded directly into fibers and yarns. However, for its print applications, CELLIANT fine mineral powder can be easily added directly onto the surface of all different fabric types. The company is particularly energized about how this expands the array of sustainable offerings that CELLIANT can be incorporated into, and is looking forward to partnering with brands to print CELLIANT on their ecofriendly fabrics. CELLIANT Print may be a cost-effective alternative to in-yarn solutions and allows for a more efficient supply chain.

fabrics or to a new fabric to create a variety of different product applications. For brands who are seeking a smaller pattern roller for apparel, orthopedic products or other close-to-skin projects, CELLIANT Print can accommodate this. There is also a larger pattern roller for bedding and larger-scale applications. As long as the print covers 80% of the fabric’s surface, the design possibilities for the print itself are virtually endless. CELLIANT Print has undergone mechanical testing for wash tests and can be confirmed to last the useful life of the product, for 50+ washes.

By applying CELLIANT Print directly onto the fabric, brand partners are able to use CELLIANT with a higher loading of bioceramic minerals than what would otherwise be possible with an in-yarn solution. This makes it ideal for recovery and performance purposes. In fact, an example of a CELLIANT Print application on kinesiology tape, KT Tape® PRO Oxygen™ was launched in April to great success.
