From the Sector

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.

At the "International Conference on Cellulose Fibers 2024" in Cologne, Germany, the Nova Institute for Ecology and Innovation awarded first place in the Innovation Prize to the project partners of the EU-funded HEREWEAR project. They presented a dress made of cellulose fibers, which is entirely made of straw pulp.

HEREWEAR is an EU-wide research project that brings together partners from research and industry. They are working to establish a European circular economy for locally produced textiles and clothing made from bio-based raw materials.
The HEREWEAR consortium consists of small and medium-sized enterprises and research institutions. HEREWEAR covers all the necessary expertise and infrastructure from academic and applied research and industry from nine EU countries.

The HEREWEAR approach includes technical and ecological innovations in the production of fibers, yarns, fabrics, knitwear and garments, as well as the use of regional value chains and the circular development of fashion items.

New technologies for wet and melt spinning of cellulose and bio-based polyesters, e.g. PLA, from which yarns and fabrics are produced, form the technical basis. Coating and dyeing processes have been developed and tested as part of the project. In addition to reducing the carbon footprint of the product, another environmental goal is to reduce the release of microfibers throughout the textile manufacturing process and life cycle.

Improving the sustainability and recyclability of the developed garments is ensured by design for circularity and digitally networked production means. On-demand production is realized in so-called "microfactories", which are individualized and produce only for actual demand. This production method can be achieved through regional, networked value chains and enables the traceability of materials and manufacturing processes.

The dress presented at the award ceremony is an example of the cooperation and the different qualifications of the project partners: TNO (Netherlands Organization for Applied Scientific Research) provided sustainably produced pulp. The HighPerCell fibers were produced in DITF's spinning facilities. At the same time, designers from the fashion label Vretena created the design for the flexible, two-piece dress, which can be knitted without cutting waste. DITF textile experts worked with the designers to develop the knitting pattern. DITF textile engineers and technicians produced the knitted fabric and assembled the dress at the institutes’ technical center. DITF computer scientists and engineers created the "value chain" and "digital twins" for digital traceability of the production processes.

The innovation prize was awarded to the HEREWEAR consortiu for their joint achievement. Representatives of DITF Denkendorf and Vretena accepted the award on behalf of the EU project partners.

ISKO provided their latest innovation in material science to British designers, Priya Ahluwalia, Masha Popova, Chet Lo and Aaron Esh, for the London Fashion Week SS24 season.

Alongside supplying their latest denim fabrics, ISKO opened its doors to its London-based product development centre, Creative Room London, for finishing and washing of their final designs as well providing expertise and knowledge in denim design and construction.

Priya Ahluwalia
For Ahluwalia’s Spring Summer 24 collection, entitled Acknowledgements, Creative Director and founder Priya Ahluwalia’s research led her on a journey of creative rediscovery.
ISKO’s Ctrl+Z fabric, which is made entirely from recycled and regenerated fibres, was used to create the flower motif denim showcase within 3 looks across jeans and jackets. This development contains no virgin cotton and uses a minimum of 60% recycled materials and the remainder is regenerated cellulose fibres while still giving a look and feel identical to traditional denim and speaks to Ahluwalia’s ongoing commitment to sustainable design and business practices.

Chet Lo
This season, Chet Lo took an active stand in reclaiming the power lost during his youth, healing the childhood wounds inflicted by a society that sidelined differences instead of celebrating them.
ISKO’s Ctrl+Z fabric and specialist lasering techniques from ISKO’s Creative Room was used across three looks featuring signature Chet Lo erotic laser prints across denim bottoms.

Aaron Esh
The SS24 season marked the brand’s debut at London Fashion Week, a homecoming of sorts for Esh, who was born and raised in the heart of the British capital, studied at Central Saint Martins and became a finalist at the LVMH Prize earlier this year. The early impulses of Aaron Esh remain steadfast: clothes that combine establishment rigour with the rebellious spirit of youth culture, devotedly crafted for a generation who feels somewhere in-between.
Aaron created bootleg denim ripped jeans made entirely from ISKO Denim using R-TWO50 fabric, which comprises a minimum of 50% pre and post-consumer recycled content. The designer noted the addition of denim accompanied by leathers add a new level of depth to their latest collection.

Masha Popova
Masha Popova’s sophomore catwalk outing, MONSTER was a “seasonless” offering that combines Autumn Winter 2023 and Spring Summer 2024.
Masha continued her obsession with denim manipulation, using various finishings including over-dyeing, flocking, patchwork, scratching and fraying in a variety of colours from vibrant green to silver across jeans, tops and jackets, all developed with the help of ISKO’s Creative Room, London.

At ITMA 2023, XORELLA, a specialist in steam setting and conditioning equipment for yarns and fabrics, will launch XO AUTOMATION for the double door XO SELECT conditioning machine series, and XO SOLID, a new machine series to complement XO SMART, XO TREND and XO SELECT machines.

XO AUTOMATION
The new XO AUTOMATION system consists of roller conveyor systems for loading and unloading two-door XO Select conditioning machines. Additional pallet wrapping machine with a turntable, weighting station, label printer, safety fence and security system can complete the system. The XO Select controller and automation system can handle and store individual customer-specific material and packing programmes.  

XO SELECT and XO AUTOMATION are designed for yarn steaming on multiple pallet dimensions and heights up to 2,650mm. The linear material flow passing conveyor and steaming machine avoids any mix between steamed and un-steamed materials. XO AUTOMATION fills the gap between the XO automated moving platform and the fully automated transport system – from spinning hall to warehouse.

XO SOLID
The new cubical XO SOLID combines a high loading space of 1,800mm x 1,700mm x 4, 000mm (H x W x L) through double row pin trolleys or pallets for easy manual loading of six units on floor level without a pit or platform. XO SOLID is therefore designed for installations on upper floor levels. The new frame design combines all necessary components factory preinstalled on a single frame, for easy ‘plug and play’ installation at the customer site. Additional smaller steamer dimensions for two and four loading units are also at the planning stage.

The new XO SOLID incorporates all the renowned features of XORELLA machines based on the long term experience in high temperature dyeing vessel production of FONG’s, including:

• A Siemens controller with OPC UA interface and XO data tool for batch storage.
• A XO EcoPac waterless claw pump or two-stage water ring vacuum pump.
• A high energy efficient accumulator for steam, electric and combined heating.
• Vessel and piping in world-class stainless steel.
• European key components such as pumps, heating elements, valves and sensors

Established in Switzerland in 1967, XORELLA became known in the global textile industry for its innovative indirect steaming system. Since 2002 the company has been a member of the CHTC Fong’s International Group, and a member of SINOMACH Group (China National Machinery Industry Corporation) since 2019.

Alchemie Technology is the latest company to join the British Textile Machinery Association (BTMA), as all of the organisation’s members gear up to showcase an array of new innovations at ITMA 2023 in Milan from June 8-14 this year.

Cambridge-headquartered Alchemie is the inventor of two technologies – EndeavourTM and NovaraTM.

The Endeavour digital dyeing system produces no wastewater and reduces water consumption by up to 95% compared to traditional dyeing. The virtually waterless process delivers dyed fabric with high colour consistency and colour fastness and does not require post dyeing washing steps which leads to an energy reduction up to 85%. It can deliver any colour shade required and enables on-demand digital colour changeovers in any run length, from a few metres to several kilometres.

Similar energy savings can be achieved with the Novara precision finishing system which utilises a nozzle array to deliver finishing chemistry with millimetre resolution. Finishing chemistries penetrate deeply into the fabric due to the combination of high velocity liquid jetting and precisely-controlled vacuum and textile finishes are applied only where needed, reducing chemistry usage and enabling multi-functionality.

In the past year, Alchemie, backed by Swedish fashion giant H&M, has established a first demonstration hub at customer JSRTEX in Taiwan. It is now progressing plans to set up further centres at customer sites around the world.

Coisne et Lambert, the group composed of the two companies TDV Industries and Klopman International, a leader in the production and marketing of technical fabrics for the professional clothing and PPE sector, announced the acquisition of TAD Teintures et Apprêts Danjoux.

TAD is specialized in the dyeing and finishing of knitted fabrics and has been in the market for over 30 years. Based in Le Coteau (France), the company has a production site of 9,000 m² and is a major player in the civil and administrative markets for technical textiles for professional clothing, medical, sport and apparel.

With a well equipped R&D laboratory, responsive and innovative sampling and production processes, TAD is ISO 14001 certified to manage its environmental performance.

TAD will extend the group's textile know-how adding expertise in knitwear finishing (dyeing, finishing and functionalities). The complimentary nature of their skillsets will allow the three companies to develop synergies for the benefit of their common and specific markets.

This integration will enable TAD to strengthen its specific business model and its services as a French finishing company over the long term, for the benefit of its historical and future customers.

The group, which is made up of the two companies TDV Industries and Klopman International, achieved a turnover of 185 million euros for the 2021-2022 financial year and employs more than 600 people. It also intends to expand its presence in new markets and geographical areas. Klopman International and TDV Industries want to offer markets more complete, flexible and competitive solutions for professional, civil and military clothing.

Monforts will highlight its technologies for special technical textile applications at this year’s ITMA ASIA + CITME which takes place at the National Exhibition and Convention Center in Shanghai, China, from November 20-24.

One of Monforts' developments is the Montex 8500 XXL stenter system for the production of technical fabrics in widths of up to 6.8 metres. Among the products made on this system are treated nonwovens for the geotextiles and filter media markets, tarpaulins, advertising banners, black-out curtains, membranes and many more.

On Montex©Coat coating lines, meanwhile, the possibilities range from the single-sided application of finishing agents for outdoor clothing and adding functionality to home textiles, to the creation of materials for sophisticated lightweight construction and automotive and aerospace components.

“Many more applications are possible, such as the overdyeing of denim, the creation of double-face coated materials, fabrics awnings, tents and medical drapes and the pre-treatment of substrates for digital printing”, explains Gunnar Meyer, Monforts area sales manager for China. “A range of different doctor blades and their combinations can be supplied to meet individual requirements, including air knife, roller knife, foam, screen and magnetic roller coating. The latter option is recommended for lines with working widths of over 2.4 metres.”

In addition, Monforts can provide the necessary explosion-proof ranges for solvent-based coatings and high temperature processes up to 320°C, such as the PTFE coating of nonwoven filter material. These lines are equipped with special burners, stenter chains, and insulation.
