How to do more with less explored at Kingpins24 Flash

  • Major Monforts denim customers continue to pioneer new initiatives that are pushing the boundaries of sustainable production.

Recycling their cotton waste has become one way these companies can do more with less, and at the recent Kingpins24 Flash online event, Sedef Uncu Aki, director of Orta, headquartered in Istanbul, Turkey, announced a new partnership with leading recycling operation Gama Recycle.

Traceable
“Through this local partnership we will supply the waste from our spinning mills and return around 3,000 tons of premium quality cotton back to them,” she said. “We have established a truly controlled and traceable system and partnering with a domestic recycling centre is important because a lot the carbon emissions associated with recycling usually come from transportation.”

“Through this local partnership we will supply the waste from our spinning mills and return around 3,000 tons of premium quality cotton back to them,” she said. “We have established a truly controlled and traceable system and partnering with a domestic recycling centre is important because a lot the carbon emissions associated with recycling usually come from transportation.”

Orta’s ZeroMax range meanwhile uses no cotton at all, being based on Lenzing’s Tencel cellulosic fibre, while the company’s involvement in denim production for a recent launch by Levi Strauss, of jeans made with organic cotton and Circulose – a breakthrough material developed by re:newcell of Sweden and partners – was hailed as a further step forward.

To make Circulose, re:newcell repurposes discarded cotton textiles, such as worn-out denim jeans, through a process akin to recycling paper. The incoming waste fabrics are broken down using water. The colour is then stripped from these materials using an eco-friendly bleach and after any synthetic fibres are removed from the mix, the slurry-like mixture is dried and the excess water is extracted, leaving behind a sheet of Circulose. This sheet is then made into viscose fibre which is combined with cotton and woven into new fabrics.

Circular Park
Omer Ahmed, CEO of Artistic Milliners also announced plans for his company’s new 70,000 square-foot Circular Park in Karachi, Pakistan, at Kingpins24 Flash.

Once complete, this will add three million square metres of additional denim capacity a month to the company’s production and take its total recycled output to a monthly five million metres.
Ahmed observed that there is currently a lack of sustainable fibres that are readily available to use for denim production at scale.

“Organic cotton is too expensive, and in my opinion always will be,” he said. “Cottonised hemp is also not cheap and it’s hard to mix with cotton, while the new regenerated cellulose fibres that are now emerging are promising, but currently in short supply. Recycled polyester is meanwhile still based on petroleum resources which we want to move away from. As a consequence, there are only a few other options for us as a manufacturer and this new project will help us minimise our own waste while significantly lowering our carbon footprint.”

Other Monforts denim customers to introduce cotton fibre recycling operations at their plants recently include AGI Denim, Bossa and Soorty.

Vertical savings
Refresh is the name of the latest collection from AGI Denim – reflecting the company’s significant reduction in water consumption.

The company has just opened new fibre spinning and denim mills at its complex in Karachi, Pakistan.

“Over the years we’ve gone through a series of backward integration steps to become fully vertical,” said AGI Denim executive director Ahmed Javed, at Kingpins24 Flash. “In our latest expansion, we revisited every step of the production processes in order to make resource savings.”

Innovations have included the installation of proprietary robotics for garment finishing, but the most attention has been paid to water savings.

“Pakistan is one of the largest cotton-producing companies in the world and we’re fortunate that the type of cotton that is grown here is well suited to denim production and also helps us lower our carbon footprint, with everything done in close proximity,” Javed said. “In the lifecycle of a pair of denim jeans, however, cotton fibre production contributes 68% of water consumption. While we cannot control how much water cotton needs for it to grow, we can rethink the way we use it in our factory.”

Refresh-branded denims are washed from 100% recycled water as a result of the company’s new wastewater treatment plant, which puts production wastewater through a series of steps beginning with equalisation, followed by aeration and concluding with sedimentation. The water travels through filtration and ultrafiltration systems before being subjected to an activated carbon system and finally a reverse osmosis system to reduce any dissolved salts.

AGI now recycles 4.4 million gallons of water each month – enough to wash a million pairs of jeans.

Sustainable
Monforts has a leading position in the field of denim finishing with its well proven Thermex continuous dyeing systems, Montex stenter dryers and other lines for resource-efficient and economical processing.

“Our denim partners are constantly setting themselves new goals in respect of sustainable production – and more importantly, achieving them,” says Hans Wroblowski, Monforts Head of Denim. “We work closely with them with the aim of constantly optimising processing parameters and achieving further savings in energy, water and raw materials throughout the dyeing and finishing stages of production.”

The latest Monforts innovation for denim is the CYD yarn dyeing system. This technology is based on the effective and established dyeing process for denim fabrics that is now being applied for yarn dyeing. The CYD system integrates new functions and processes into the weaving preparation processes to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre in Mönchengladbach, Germany.”

Sustainable leadership for GtA with new Monforts Montex wide width lines

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.
