From the Sector

In recent years, Italian circular knitting machine manufacturer Santoni (part of the Lonati Group) and Groz-Beckert have worked together to develop a new self-cleaning knitting system for the INNOTAS circular knitting machine. The knitting system is also called INNOTAS and consists of the circular knitting machine needle SAN™ DUO and the corresponding sinker SNK DUO-OL.

Following various preliminary investigations, the go-ahead was finally given in January 2015 for the joint development of a self-cleaning system in the needle area with side-by-side needles and a low shank.

The circular knitting machine needle SAN™ DUO with the sinker SNK DUO-OL was developed to meet the desired requirements. In the knitting system, there are two needles in the needle channel and two sinkers in one sinker channel. The benefits became apparent in initial field trials with experienced end customers in 2016. In the following years, the knitting system was continuously analyzed and further optimized.

The double filling in the needle channel significantly reduces soiling. In addition, the further developed shape of the knitting system ensures that any yarn lint is automatically removed from the machine during the knitting process. This extends the cleaning interval, making work more time-efficient and increasing productivity.

Both the needle SANTM DUO and the sinker SNK DUO-OL are characterized by a particularly low shaft with a predetermined breaking notch. The low shank minimizes soiling, while the predetermined breaking groove enables controlled needle breakage in the event of wear at the desired point. This reduces errors in the knitting process and machine downtimes.

The exhibition “Acquired! Shaping the National Design Collection” at Cooper Hewitt, Smithsonian Design Museum, which opened on 16 March, features a STOLL work that has been part of the museum’s permanent collection since 2017.

Visitors can expect more than 150 works that have been compiled from the museum’s collection and new acquisitions since 2017. The selection, which includes works by design pioneers of the recent past, also includes a highly functional balaclava from STOLL.

Blend of design and functionality.
The flat knitted balaclava from STOLL is part of an exhibition area that visualises the defining themes of our time. Alongside a hijab, it stands for considering inclusivity in design. The balaclava offers protection from extreme cold, is stylish and is the result of a combination of creativity and technology.

The balaclava integrates an NFC chip for near-field communication, a heater to warm breathable air, a positive and negative power connector and reflective strips for passive visibility, all knitted directly into the fabric. STOLL’s state-of-the-art flat knitting technology is the basis for straightforward integration. Circuits and conductive yarns can also be incorporated in a fully automated process exactly where they are needed.

Other performance features do not require additional components. A knitted-to-shape 3D design – made possible by the goring technique – offers a perfect fit by following anatomy and eliminating the need for complex tailoring.

With the aim to help the denim industry reduce the environmental impact of its wastewater and move towards circularity, Archroma, G-Star RAW and Advance Denim have renewed their joint commitment to the production of aniline-free denim apparel based on Archroma’s DENISOL® PURE INDIGO 30.

Their joint aim is to produce high-quality denim in authentic blue shades without the aniline impurity carried through from the synthesis of standard synthetic indigo. In traditional denim production, this aniline remains bound with the indigo pigment on the fabric; the remaining aniline is discharged during the dyeing and washing process. This can be a problem because aniline is toxic to aquatic life and two-thirds of aniline waste currently ends up in wastewater discharge where it could potentially pollute waterways and the ocean.

Archroma developed DENISOL® PURE INDIGO 30 to answer this key challenge. A 30% pre-reduced indigo solution, DENISOL® PURE INDIGO 30 makes it possible to produce indigo-dyed denim without aniline impurities throughout the process.

Easy to use with automated dosing, DENISOL® PURE INDIGO 30 reduces the water needed for preparation, washing and wastewater treatment compared to indigo grains. It also reduces hazardous chemical consumption while allowing high reproducibility and creating the authentic and iconic deep indigo shades traditionally associated with denim.

G-Star RAW is working towards making 20% of its entire collection from Cradle to Cradle Certified® fabrics by 2025. Its partnership with Archroma and Advance Denim contributes to this goal, since the aniline-free DENISOL® holds a Gold Level Material Health Certificate from the Cradle to Cradle Products Innovation Institute. DENISOL® PURE INDIGO 30 is also compliant with other eco-standards and the requirements of leading retailers and brands.

Advance Denim, G-Star RAW and Archroma have previously collaborated to launch collections based on Archroma’s EarthColors® technology, which upcycles plant waste from the herbal industry to create sustainable colorways.

First launched in 2014, 2024 marks 10 years since Spezial's inception. Ringing in this landmark anniversary, Gary Aspden and the three stripes chart a course through the label’s past, present, and future – their latest collection telling the timeless story of adidas’ design DNA.

Headlining the collection is the Todmorden Smock. First released in Spring Summer 2021 to an immediate sell out, this season the coveted style returns in two colourways: navy and white. A commemorative 10th anniversary Mod Trefoil tee then brings the Spezial spirit to life as a certified collectors item.  
 
Two lightweight jackets – the Trentham and the Wingrove – constitute spring layering items, while the matching Angelzarke track top and track pants are awash with signature Spezial details. The apparel offering is then rounded out by the Rossendale Short, a Polo shirt, and the Lytham tee.
 
The accessories offering comprises of the Brinscall bag, a Mod Trefoil cap, a two pack of socks, and a Mod Trefoil towel.

Trützschler expanded their portfolio to become the first full-liner in the preparation of textile waste – from mechanical recycling to the spinning preparation of torn secondary fibers.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

Success with a systems approach
Recycling systems face significant technological challenges. On average, torn fibers are much shorter than virgin fibers. The percentage share of short fibers in the fiber mass is much higher. Unopened yarn and fabric particles are also difficult to process. Not surprisingly, much academic and practical research is currently conducted to find solutions for these problems. Dr. Georg Stegschuster, a researcher specializing in textile recycling, believes a systems approach is needed. He is working at the Recycling atelier, a model factory for mechanical recycling in Augsburg, Germany, which is committed to delivering the latest technological insights for textile recycling. “A perfect fine-tuning between tearing and spinning preparation is key for obtaining the best possible quality results and avoiding unnecessary fiber shortening,” he says. “This can be achieved if you are in control of both processes – and have the necessary expertise for both processes too.”

Gentle but effective
In some cases, for example, it may be advantageous to have less aggressive settings in the tearing line. This can help avoid unnecessary fiber shortening. The remaining higher share of unopened fabric must then be handled in a high-performance spinning preparation line. This starts with the right blow room configuration for perfect opening, cleaning and blending. A card that is specially designed for recycling materials, such as the new TC 30Ri, can also enable gentle but effective treatment of fibers.

A shortened drafting process is also a must. The integrated draw frame IDF 3 can make this possible. The draft is high enough to provide excellent levelling of the numerous short fibers, but low enough to prevent floating fibers.

Full-liner in mechanical recycling and preparation of textile waste
Trützschler now offers a complete system covering the whole process, from cutting and tearing textile waste through to carding and drawing secondary fibers. Thanks to this holistic approach and Trützschler’s expertise for the whole process, manufacturers can avoid unnecessary fiber shortening.
