From the Sector

During the Innovate Textile & Apparel (ITA) virtual textile machinery show which will run from October 15th-30th 2020, Monforts will be emphasising its leadership position in three key fields – advanced coating, denim finishing and fabric sanforizing.

With its multi-head capability, the latest Monforts texCoat coating system provides flexibility with an unprecedented range of options and a wide range of modules available.

Refinements
“Since we acquired the coating technology that our systems are based on we have made a lot of refinements and all of them are reflected in higher coating accuracy and the resulting quality of the treated fabrics,” says Monforts Head of Technical Textiles, Jürgen Hanel.
“Our systems have the shortest fabric path from the coating unit into the stenter and we have all variations of coating application systems too – and all of these options are available in wider widths, with the engineering and manufacturing from a single source here in Europe.”

CYD
Denim finishing is meanwhile a field in which Monforts has an undisputed lead and it has been working closely with its many partners in the key denim manufacturing countries of Bangladesh, Brazil, China, India, Mexico Pakistan and Turkey to develop advanced solutions. The latest of these is the CYD yarn dyeing system.
“CYD is based on the proven Econtrol® dyeing system for fabrics*,” explains Monforts Head of Denim Hans Wroblowski. “It integrates new functions and processes into the weaving preparatory processes – spinning, direct beaming, warping and assembly beaming, followed by sizing and dyeing – in order to increase quality, flexibility, economic viability and productivity. The CYD system has been developed in response to a very strong market demand.”

Pre-shrinking
Monforts has also recently delivered a significant number of its latest Monfortex sanforizing lines to customers around the world.
Sanforizing is vital to final fabric quality, pre-shrinking it by compressing prior to washing, to limit any residual or further shrinkage in a made-up finished garment to less than 1%, for perfect comfort and fit over an extended lifetime.

As with industry-leading Montex stenters, Monfortex lines benefit from the latest Qualitex 800 control system which allows all parameters to be easily automated via the 24-inch colour touchscreen, including production speed, control of all fabric feed devices, rotation spray or steaming cylinder options, the width of the stretching field and the rubber belt pressure. Up to 10,000 separate process parameter records can be generated and stored by the data manager.

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.

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.

Monforts Textilmaschinen GmbH & Co. KG will be providing information on its extensive range of coating and finishing technologies for the production of nonwovens and technical textiles at the forthcoming Techtextil India exhibition.

“India is already a very important market for Monforts and there are exciting prospects ahead for Indian manufacturers of technical textiles, who are well positioned to capitalise on growth opportunities,” says Monforts Head of Denim Hans Wroblowski, who will be at the Monforts stand in Hall 4, booth C52 at the show. “India has one of the largest working-age populations in the world and a complete textile value chain for both natural and synthetic fibres.”

In addition, he adds, India’s government, through its Ministry of Textiles, has been actively promoting the growth of technical textiles through various programmes based on investment promotion, subsidies, the creation of infrastructure and the stimulation of consumption.

As a result, India’s Ministry of Textiles is forecasting that the growth of technical textiles in the country will be over 18% annually in the next few years, from a value of US$16.6 billion in 2018 to US$28.7 billion in 2021.

Value addition

High value-added technical products such as wide-width digital printing substrates, carbon fabrics for high-performance composites, filter media, flame retardant barrier fabrics and heavy-duty membranes are now being coated on Monforts texCoat ranges and finished with the company’s industry-leading Montex stenters.

“Since we acquired the technology that our coating units are based on in 2015, we have made a lot of refinements,” says Hans. “All of these developments are reflected in higher coating accuracy and the resulting quality of the treated fabrics. At the same time, our latest multi-functional coating heads offer an unprecedented range of options, with a wide range of modules available.”

The texCoat user interface is now equipped with the unique Monforts visualisation system and the magnetic doctor blade has greater power reserves. Options include a carbon fibre-reinforced composite coating drum with a more scratch-resistant surface and maximum rigidity and remote control which simplifies exact adjustment for the operator.

Montex stenters in special executions are meanwhile ideal for the drying and finishing of both technical woven fabrics and nonwovens and characterised by high stretching devices in both length and width.

“The European-built Montex range of stenters has earned its leading position in the technical textiles market due to the overall robustness, reliability and economy of these machines,” Hans concludes. “Whatever the intended end-product – and we continue to discover potentially new areas in which technical textiles can be utilised all the time – we have the machine specification and know-how to turn ideas into reality. In India we also benefit from the strong sales and service support of A.T.E. Enterprises.”

Texchtextil India takes place alongside World of Composites at the Bombay Exhibition Centre in Mumbai from November 20-22.
