From the Sector

Deakin University has signed a partnership agreement with Geelong-based company Xefco as part of its Recycling and Clean Energy Commercialisation Hub (REACH) to conduct new research to transform how our clothing, including jeans, get their colour.

Jeans are one of the most worn garments in the world, but they are also one of the least environmentally friendly, taking around 75 litres of water to dye just one pair.

Deakin’s work with Xefco is helping to explore if a waterless manufacturing process can replace the water intensive processes the clothing industry has used for hundreds of years. The new technology in development is called ‘Ausora’.

Associate Professor Alessandra Sutti, from Deakin’s Institute for Frontier Materials, said it was exciting to be on the commercialisation journey with Xefco, working with the company to discover what is possible and hopefully reduce the world’s fashion footprint.

“If successful, the Ausora technology, which colours fabrics without the need for large quantities of water, will put us a step closer to more efficient and sustainable clothing manufacturing,” Associate Professor Sutti said.

Xefco CEO Tom Hussey said the company’s new pilot plant, housed at Deakin in Geelong, will test different materials, including specialised fabrics such as waterproof items like outdoor jackets and jeans.

“This is the first stage of Xefco’s vision for the technology, with the REACH project focused on demonstrating the commercial viability of the technology at pilot scale and developing processes so it can be scaled up for commercial production,” Mr Hussey said.

“Together, Deakin and Xefco will push the limits of innovation and see what is possible.”
Xefco’s pilot plant is co-located with Deakin researchers at ManuFutures, the state-of-the-art advanced manufacturing hub at Deakin’s Waurn Ponds campus.

Founded in 2018 Xefco now employs 17 people and its products are already making a difference across the world. Its XReflex technology, which reduces consumption of insulation materials, is being used by some of the world’s leading apparel and fashion brands including The North Face.

Backed by a $50 million grant from the Australian Government’s inaugural Trailblazer Universities Program, with industry and university support taking the total project value to $380 million, REACH is facilitating the development of greener supply chains and accelerating business success as markets move from a throughput economy to a circular economy.

Finishing machinery specialist Monforts has secured a number of major orders from textile manufacturers in Central and South America recently, and was pleased to welcome a high number of visitors from the region to its stand at ITMA 2023 in Milan from June 8-14.

Among new orders are those for three Montex stenters delivered to the AustralTex Group in Argentina and a further Montex range to denim manufacturer CIT in Brazil. Guatemala’s Global Textiles placed an order for its second Montex stenter, while Mexico’s Zentrix ordered its third and Avante, also in Mexico, has opted for its sixth.

Elsewhere, orders have also been placed for the delivery of three new Montex stenters to one of Pakistan’s major corporations, as well as a new Thermex dyeing range to nonwovens manaufacturer Orsa in Italy. Further orders – both for new machines and retrofit modules – are now anticipated following ITMA 2023, which attracted over 111,000 visitors to Milan.

“Visitor footfall at ITMA 2023 was well beyond the company’s expectations, and we were especially pleased at the constant number of visitors from South American companies, as well as from Asia and Europe,” said Monforts Marketing Manager Nicole Croonenbroek. “We were able to provide them with detailed information about our portfolio of machines and technologies digitally and fielded an unprecedented number of serious enquiries, many of which promise to turn into new business.”

Monforts Montex stenters for processes such as drying, stretching, heat-setting and coating, she added, are already the industry standard for the fabric finishing industry, providing a number of advantages in terms of production throughput and especially in energy efficiency and resource savings. Other key technologies in the Monforts portfolio include relaxation dryers, Thermex dyeing ranges and Monfortex compressive shrinking ranges.

Montex®Coat
“We were also very pleased with the interest in the Montex®Coat, the latest addition to our range of technologies, which we displayed in Milan,” Croonenbroek said.

The Montex®Coat can serve a very diverse number of markets and enables full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments, as well as solvent coatings. Knife coating, roller coating or screen printing can also all be accommodated with this system. It provides the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

Many refinements have been made to the Montex®Coat in the past few years, resulting in higher coating accuracy and the resulting quality of the treated fabrics. A number of advanced new improvements were introduced in Milan, including automatic edge limiters for immediately adapting to new coating widths and a new and simplified hand-held control device. These save considerable time in setting up the machine and ensuring consistent production.

The Montex®Coat unit displayed in Milan was sold to Vietnamese company Thai Tuan during the show.

Pulcra Chemicals and Inditex develop Sustineri Coloring, a combined pretreatment and dyeing process for cotton and polyester/cotton resulting in water, time and energy savings. This process is the result of a joint research between Pulcra Chemicals and Inditex with the goal to mitigate the impact of standard dyeing processes and to reduce the use of natural resources.

Sustineri Coloring is based on newly engineered process chemicals which allow a one bath pretreatment and dyeing process for dark, medium and light shades of cotton and polyester/cotton fabrics by exhaust method. This results in shorter processing time and less use of water and energy.

The process is already used by selected mills and it showed that Sustineri Coloring is reducing in pretreatment and dyeing the processing time by up to 60 % and the water and energy consumption by up to 80 and 60% respectively. The state-of-the-art products allow a one bath treatment which is the key in saving resources.

Fong’s Europe will showcase the advanced features of its THEN Smartflow TSF at ITMA 2023.

These include the machine’s smart fabric transport system which ensures extremely even dyeing of the fabric through accurate control of the nozzle pressure and pump power, with movement through the machine via an PLC-controlled plaiting system and variable chamber adjustment depending on fabric characteristics.

The machine is equipped with a heat exchanger enabling it to heat the dyeing liquor quickly and efficiently, to reduce energy consumption. Its bath preparation unit and chemical dosing system ensure accurate and precise dosing of chemicals, dyestuff and salt, reducing chemical waste and optimising results while reducing process times.

The Smartflow TSF operates with a low liquor ratio of down to 1:2.5 with full loading of synthetic fabrics, which means that it requires less water to dye a given amount of fabric compared to traditional dyeing machines. This not only reduces the consumption of water and steam, but also the amount of wastewater generated.

The machine's control panel is easy to use, allowing operators to programme and monitor processes with ease.

CHT and Fulgar have collaborated to support the goal of reducing the carbon footprint with an effective and sustainable solution for the textile market.

Combining FULGAR’s circular economy ready yarns with CHT’s resource-saving dyeing techniques significantly reduces the usage of natural resources and leads to lower environmental impact and ultimately a lower carbon footprint. The combined process needs less water, uses less energy, and saves time while meeting the color fastness standards for finished textile products.

The combination of 100 % biobased polyamide EVO® by FULGAR yarns with CHT sustainable dyeing application can save water up to 64 %, energy use up to 50 % and process time up to 50 %, when compared to standard dyeing processes. Sustainable dyeing of EVO® is promoted using CHT’s soy-based dyeing auxiliary SARABID TS 300. SARABID TS 300 has accredited a C2C Certified Material Health Certificate at Gold level and USDA Certified Biobased Product Certification.

EVO® by FULGAR, the totally renewable yarn based on castor plants, does not require high amounts of water - 4 times less compared to cotton. In addition to the sustainable aspect, EVO® by FULGAR offers characteristics like lower fiber weight, particular moisture management and higher stretch often without the need for elastomer fiber. This helps to avoid material mixes for better recycling opportunities. EVO® provides greater user comfort, mainly for performance and casual apparel.

• Reactive dyes for water and energy saving dye processes with significantly shortened process time

BEZAKTIV ONE covers a broad color spectrum with tinctorial very strong dyes. This enables a cost-efficient dye process with significantly less dye and salt. The excellent wash-off behavior allows short rinse cycles at lower temperatures and therefore offers further ecological and economic advantages. The dyes are particularly suitable for durable textiles due to their good multiple wash fastness.

Cellulosic fibers are often dyed with reactive dyes, as these are commercially available in a wide range of colors that result in dyeings with high wash fastness. However, reactive dyeings require a lot of water due to the necessary rinsing processes. Due to increased ecological requirements, the development of energy and water saving processes is not just a trend, but rather a core prerequisite for new dyes.

A minimal number of rinsing baths and generally lower temperatures for dye exhaust, rinsing and soaping contribute to an overall efficient water and energy saving dyeing processes.

BEZAKTIV ONE dyes can be dyed, rinsed and soaped between 40 and 60 °C. Therefore, the BEZAKTIV ONE exhaust dyeing process is significantly shorter compared to conventional reactive dyeing processes, where temperatures between 60 and 98 °C are required. This advantage means savings in process time and higher productivity for the textile dyer.

The advantages become particularly clear when dyeing medium to dark shades with the BEZAKTIV ONE process. Due to the high fixation level in combination with good color build-up dark shades can be matched with lower dye concentrations of BEZAKTIV ONE than with conventional bifunctional reactive dyes. The addition of the auxiliary COTOBLANC SEL in the second soap bath has an additional positive effect, so that a washing process with low water and energy consumption generates excellent wet fastness properties on the textile.

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.

Within its TEXTILE SOLUTIONS, the CHT Group has developed solution approaches for manufacturing companies in the textile value chain that have to use a lot of energy for their production. This is intended to compensate high energy costs and make a positive contribution to climate protection.Application specialists work with customers to develop individual savings potentials that are specifically tailored to the production facilities and requirements. Thus, depending on the process, fabric and machine, energy savings of up to 30% can be achieved with the use of innovative CHT textile auxiliaries, dyes/pigments and the corresponding process optimisations. In addition, the numerous concepts and optimally matched products can minimise water consumption or shorten the process time.

Energy-efficient cold bleaching instead of pad-steam bleaching processes in continuous pretreatment and the 4SUCCESS process for energy-efficient and resource-saving pretreatment and dyeing of cotton help to save energy. Likewise, the use of polymer binders, which do not require energy-intensive fixation, saves energy.

Efficient pretreatment with the new polymer technology CPT (Comb Polymer Technology) achieves good cleaning effects even with low liquor ratios and thus less water to heat up. To save costs for energy-consuming heating, there is also the gentle low-temperature fixation in the easy care finishing. The OrganIQ EMS Jeans system enables jeans finishing with a reduced application temperature compared to standard processes.

With TIME BOOST, a process for fast polyester dyeing processes, not only significant energy but also time savings are achieved by omitting pre-washing and by shortening heating and migration times. SHORT CUT also leads to shorter process times when dyeing polyamide.

To avoid cost-intensive intermediate drying, the CHT Group offers the SCREEN-2-SCREEN with PRINTPERFEKT S2S which facilitates printing in a wet-on-wet technology.

In addition to numerous other products, the CHT Group also offers its customers digital tools to optimally support process optimizations. The "BEZAKTIV Soaping Advisor" calculation program within the CHT Textile Dyes app can be used to evaluate and improve dyeing and soaping processes in a simple and target-oriented way.
