From the Sector

Monforts, which is celebrating its 140th anniversary this year, will exhibit a Montex stenter chamber with an integrated overhead heat recovery unit at the forthcoming ITM textile machinery exhibition in Istanbul from June 4-8.

The heat recovery unit on display at the stand of Monforts partner Neotek is just one of a range of energy saving options the company is now providing for both new and existing line installations.

Monforts Montex stenters and Thermex dyeing ranges are industry standard for the fabric finishing industry, providing many advantages in terms of production throughput and especially in energy efficiency and savings.

coaTTex
At ITM, Monforts will also introduce its latest coaTTex coating unit, dedicated to air knife and knife-over-roller coating. For single-sided application with paste or foam, the versatile coaTTex is suitable for both incorporation into existing finishing ranges as well as installation with new Monforts lines, especially Montex stenter systems.

A wide range of coatings can be applied to fabrics for providing functions such as waterproofing, liquid and gas protection and breathability, in addition to foam lamination and coating, including black-out coating.

Central location
“In Turkey we are very strongly supported by our representative Neotek, our solution partner on the ground for service, installation and commissioning, providing specialised and rapid help to all of our customers,” says Monforts Area Sales Manager Thomas Paeffgen. “ITM is always one of the most important exhibitions for Monforts, for meeting customers not just from Turkey, but across the Middle East and Central Asia, as well as Bangladesh, India and Pakistan.

“Istanbul’s centralised position makes it accessible to the majority of the major textile manufacturing hubs and as we mark our 140th anniversary in 2024, having been founded back in 1884, the ITM show will provide us with the ideal opportunity to celebrate with colleagues and customers all together in one location.”

Monforts' new Montex 8500 stenter line was recently installed at Curt Bauer’s plant in Aue in Germany.

Curt Bauer has been in continuous operation for 150 years, beginning as a weaving mill in Aue in the Ore Mountains region of Saxony back in 1882. Today, with 120 employees, the company has an annual production of 2.2 million metres of fabric and specialises in three key fields – home textiles, special damask fabrics for West African garments and technical textiles.

A first Montex stenter was installed by Monforts at the Aue plant in 2003 and an older machine from a third party supplier was also still in operation prior to the latest upgrade.
“The replacement of our older existing stenter, which was installed in 1985, was long overdue,” explains Gert Bauer. “It had a maximum working width of 2.2 metres and we were looking to both increase productivity and reduce energy requirements.”

As a consequence, the company opted for a new Montex 8500 line with a working width of 3.2 metres equipped with the MonforClean heat recovery and exhaust air purification system. The Montex stenter remains unmatched in terms of its robustness and long service life and with MonforClean technology, the waste heat from the drying process is used to pre-heat the drying air. This results in a radical reduction in the conventional heat supply required, compared to full gas and thermal oil heating. Overall energy savings of up to 40% can now be achieved compared to conventional stenters.

The first challenge at the Aue plant was how to fit the significantly larger machine into the available space without restricting the area required for docking operations.

The special multi-level configuration that Monforts designers and Curt Bauer’s team devised in order to meet these requirements involved raising all of the line’s drying zones – with a combined length of over 28 metres – on scaffolding platforms, to enable the ground floor space below them to continue to be fully utilised.

The next challenge involved configuring the MonforClean system without having to make any costly changes to the roofing structure. This, Gert Bauer observes, demanded “millimetre precision”.

With the new line now fully operational, the savings it is providing have yet to be fully calculated.

Trumpler has teamed up with Archroma to offer a leather production process that can be used to produce high-performance leather in a more eco-friendly and cost-efficient way.

The new process DyTan®combines offers an alternative to existing metal-free and chrome-tanned leather. It enables the reliable production of leather with great shavability, color depth and migration and abrasion resistance. Free from metal salts and reactive aldehydes, DyTan® is suitable for a wide range of leather applications, from garment and footwear to automotive and furniture upholstery, for today’s eco-conscious leather producers and consumers.

At the core of the DyTan® process is Archroma’s patented AVICUERO® System, which is based on novel molecules that enable more sustainable leather tanning and dyeing, developed by Archroma in cooperation with leather technology consultant Dr Leather. It enables collagen fibers in the leather to be covalently cross-linked through a simplified process at low temperatures. As a result, the system shows strong potential to save energy and water, while also reducing process time and CO₂ emissions by up to 23%.*

The DyTan® process combines the AVICUERO® System with Trumpler’s bio-based fatliquors and retanning agents based on functional biopolymers produced from hydrolyzed shavings – resource-saving technology that Trumpler has been refining for 15 years.

As a global partner of Archroma, the Trumpler Group is responsible for the distribution of the AVICUERO® System worldwide. Delivering technical support and first-class customer care, Trumpler will help leather manufacturers and brands to implement sustainable tanning and draw on its comprehensive product portfolio and process knowledge of tanning, retanning and fatliquoring processes.
 

* Estimations carried out with the Archroma ONE WAY Impact Calculator show energy savings of up to 25% and reduced process time leading to a reduction in CO₂ emissions of up to 23%, compared to traditional chrome tanning. They also show significant water savings compared to other metal-free tanning systems¹. With the ONE WAY Impact Calculator, customers will be offered personalized calculations for their specific processes.

An openly accessible online energy savings calculator for all users of powder coatings has been launched by AkzoNobel.

All powder coatings customers can instantly calculate the energy and carbon reduction they could achieve with the company’s Interpon products and related services.

It's the latest example of how the company is continuing to work towards its ambition of reducing carbon emissions across the full value chain by 50% by 2030. “Sustainability is critical for all of us and helping customers to reduce energy is one of the many ways we can work with – and for – them in order to meet our shared ambitions,” says Jeff Jirak, Director of AkzoNobel’s Powder Coatings business.

To make using the tool as easy as possible, the calculator – currently only available in Europe – is supported by a detailed guide, which helps customers better understand how even making small changes in the powder coating process can have a big impact in terms of becoming more energy efficient. These include checking for leakages in compressed air systems, improving insulation and ensuring all process equipment is regularly serviced and maintained. Customers also receive expert support from Interpon’s technical service team.

At ITMA 2023 in Milan from June 8-14, BTMA member VeriVide will introduce UltraView – its first all-LED light booth for achieving a new level of consistent and standardised colour assessment.

The company’s light booths and lighting cabinets are specified by major global retailers around the world, who rely on them for establishing and maintaining visual quality standards across their supply chains.

This is no easy feat, given the textile industry’s complex structure and the many process stages each individual garment undertakes from the designer’s desk to the finished garment on the retail shelf – often criss-crossing several continents during the journey.

Benefits
UltraView brings a range of sustainable new benefits to designers, mills and brands, and combined with VeriVide’s successful DigiEye system for non-contact colour measurement and digital imaging, can have a positive impact on a company’s bottom line, bringing savings in time, money and CO₂ emissions.

The new all-LED light booth meets all relevant international lighting and colour assessment standards. The UltraView incorporates the company’s A rated CIE D65 and CIE D50 artificial daylight light sources and includes multiple pre-set point of sale light sources while being fully tuneable for recalibration to the individual requirements of each customer. In the past, individual light booths have had to be dedicated to the stipulated settings of each specific customer’s switch sets. The rapid flexibility of UltraView, however, makes the need for multiple light booths a thing of the past.

It also eliminates the need for the regular bulb changes that were necessary with fluorescents, to provide significant energy savings.

As supply chains continue to move towards digitisation away from time-consuming and expensive physical sampling, a version of the UltraView, VisionView, is available with an internal monitor to enable physical samples to be compared with their digital versions, if required.

DigiEye
For non-contact colour measurement and digital imaging, VeriVide’s DigiEye collects and processes data that can be communicated and shared instantly, enabling manufacturers, producers and processors to speed up quality control, sustain product integrity and reduce waste.

DigiEye also overcomes the limitations of spectrophotometers, which are limited to products with a solid colour appearance and can only measure ‘average’ colour, assessing the limited area of the product exposed in the instrument’s aperture.

These limitations are further compounded if the product has any form of multi-coloured characteristics or appearance, an uneven or inconsistent surface, a colour area too small to be captured by the instrument or any sort of surface effect, such as carpet pile and the sheen of satin and silk.

Groz-Beckert will be represented at ITMA with its six product sectors and will showcase its various innovations. The presentations at the booth will be supported by augmented reality applications. This allows visitors to discover the products both live and virtually.

The Knitting product sector will be represented at the Groz-Beckert stand with its four product groups circular knitting, flat knitting, legwear and warp knitting. In the circular knitting segment, for example, two newly developed knitting systems will be on show which have been realized in collaboration with machine manufacturers. The developments focus on energy savings, extended cleaning intervals and increased process reliability.

In addition to the machines for weaving preparation, the Weaving product sector will present its recently expanded portfolio of technical weaving reeds. The new weaving reeds make it possible to supply customers who produce fabrics with high densities. The weaving reeds are used in the production of special fabrics, for example, in technical filtration, membrane technology, solar cells or touch screens.

Products and services for classic needling and hydroentanglement will be presented by the Felting (Nonwovens) product area. In the field of felting needles, visitors can look forward to two innovations: a new notch shape and the Groz-Beckert felting needle module. In the felting needle module, the needles are embedded as a module in a plastic mold for the first time. The needle modules are characterized by high deformation resistance and offer new dimensions in needle density.

For the production of tufted floor coverings such as carpets, bath mats or artificial turf, the Tufting product sector will be presenting its proven Gauge Part system.

Various new and further developments will also be shown by the Carding product area. For those interested in the nonwovens industry, for example, the world's finest Interlocking wire for reduced risk of crashis included. For customers of the spinning industry, the division will be presenting further developed stationary flats and revolving tops. The new revolving tops have been adapted to the processing of fine yarns, while the stationary flats have been provided with a new, resistant aluminum profile.

The Sewing product sector is focusing on the presentation of its special application needles, SANTM. The sewing machine needles of the SANTM series have been specially developed for demanding sewing operations – e.g. for sewing technical or finest textiles. The division will also be presenting its new Needle Finder. The Needle Finder is an interactive tool in the online customer portal that helps customers select the right needle.

International technology group ANDRITZ has delivered, installed, and commissioned a mechanical textile recycling line and an airlay line at Novafiber’s nonwovens production mill in Palín, Guatemala. Both lines have been successfully operating since December 2022.

The recycling line – the second tearing line ANDRITZ supplied to Novafiber – processes post-industrial textile waste from Central America. The recycled fibers feed the latest ANDRITZ Flexiloft airlay line, which produces nonwoven end-products for the bedding and furniture industries – a true example of a circular textile-to-nonwoven approach. The production process ensures complete material use as a state-of-the-art edge trim recycling system returns any waste directly to the tearing and/or airlay line.

This combination of ANDRITZ tearing and airlay lines allows Novafiber to process large amounts of post-industrial garments, controlling the supply chain from raw material to final product. In addition, it enables energy savings and a reduced carbon footprint due to the reduction of shipments.

Based in Palín, Novafiber is a leading company in Guatemala for producing nonwovens from post-industrial textile waste for both the local market and export.

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.

The partnership will aim at eliminating hazardous Potassium Permanganate Spray and most manual processes in denim finishing, while reducing Greenhouse Gas emissions, water and chemical use in the process

Hong Kong based Epic Group, a leading garment manufacturer for global brands today announced its strategic partnership with CleanKore, a denim innovation and patent licensing company. This partnership aims at scaling the CleanKore patented yarn dyeing technology that provides numerous sustainability benefits for both the denim mill and garment manufacturer.

CleanKore patented technology changes the chemistry and the process used to dyeing yarns at the denim mills by keeping intact the white core of the yarn and only dyeing the surface. This technology significantly reduces water, chemicals and process time in the denim garment finishing stage.

Denim garment finishing often involves onerous manual processes such as handsanding and hand whiskering, spraying of harmful Potassium Permanganate (PP) (done by heavily protective equipment donned personnel), and multiple washing cycles. CleanKore technology coupled with lasers enable elimination of the PP spray process, significantly improving health and wellbeing of apparel workers, as well as emissions of harmful chemicals. Manual processes are eliminated in most styles and significantly reduced in others.

CleanKore technology also enables the reduction of wash cycles – reducing water, chemical use and process time, adding to the sustainability credentials of the end products. The products currently tested by Epic Group and CleanKore demonstrate up to 44% of water savings in garment finishing and up to 60% of energy savings in the fabric dyeing stage, along with the elimination of PP spray.

Through their partnership, Epic Group and CleanKore are planning to rapidly scale up the adoption of this technology in partnership with Epic Group’s customer base. In the first year, the partnership plans to reach over 4 million pairs of denim and working towards a scale of 15 - 20 million pairs of denim per annum in the next 3 years, converting a large portion of Epic Group’s denim production to CleanKore technology.

Monforts is introducing a range of modular upgrades that can be added to existing finishing lines already in production.

The Monforts universal Energy Tower – a flexible, free-standing air/air heat exchanger for recovering the heat from the exhaust air flow of thermal processes – can result in a 30% reduction in the energy consumed by a line, depending on the exhaust air volume and operating temperature.

A Monforts Eco Booster, completely integrated into the chamber design of the Montex stenter, is another retrofitting option. As a single state-of-the-art heat recovery system with automatic cleaning, it can be added to existing ranges. For ranges of up to eight chambers only one module is necessary to achieve significant energy savings.

On an eight-chamber stenter with an operating width of two metres carrying out a fixing process on a 150gsm woven fabric, for example, the energy savings have been calculated to be 35% over an annual schedule of 6,000 operating hours.

In addition, the Eco Booster consumes only minimal amounts of water during the cleaning cycle and the entire process is controlled and monitored automatically.

The Matex Eco Applicator is an alternative to the conventional padding process for energy-conscious finishing and achieving considerable savings in the energy required for drying treated fabrics. The precise amount of chemical can be applied to the fabric and with less residual moisture after application of only approximately 35% so that less drying capacity is required in the stenter, which leads to huge energy savings.

Finishes can be evenly applied on either or both sides of the fabric, and two separate treatments can be applied to front and back. This makes the unit ideal for the production of, for example, double-performance hydrophobic/hydrophilic fabrics for professional clothing, as well as the over dyeing or finishing of denim fabrics.
