Ibrahim Fibres: Lighthouse Solutions in Pakistan with Trützschler

Ibrahim Fibres operates nearly 200 Trützschler cards, which is more than any other business in Pakistan. The leading yarn and Polyester Staple Fiber (PS) manufacturer has partnered with Trützschler for over two decades - and recently wanted to start processing long polyester and viscose fibers. It's an unusual request that brings unique challenges.

Pakistan is the eighth largest exporter of textiles in Asia and has the third largest spinning capacity in the continent. Ibrahim Fibres, located in Faisalabad, is a big contributor to that economic strength. The pioneering company produces a wide range of yarns for woven, and knitted fabrics. This includes various blends of cotton, viscose and polyester in different proportions and combinations with yarn counts ranging from Ne 8 to Ne 50. Ibrahim Fibres uses its own polyester via 240,000 spindles at four factories, mainly to produce poly-viscose and poly-cotton combed yarn. In total, the company manufactures 1,200 tons of PSF per day and consumes around 100 tons of its own materials per day. The remaining material is sold to other textile manufacturers.

An unusual challenge
Teams from Ibrahim Fibres often approach Trützschler with fresh ideas and new expectations. They recently set the challenge of producing top-quality yarns from unusually long polyester and viscose fibers. These fibers are used for luxury textiles, high-performance fabrics, fine bedding and advanced nonwoven materials. The end products benefit from the fibers outstanding strength and durability. Often, people in the textile industry talk about the problems with processing short fibers. But long fibers also present difficulties because they have a tendency to wrap or clog carding elements. Their length also makes them more tightly bound, which means they are more difficult to open.

What was the answer to this unusual challenge? Collaboration! Experts from Trützschler worked closely with partners at Ibrahim Fibres to explore potential solutions. "Our technical teams regularly collaborate with Trützschler’s R&D department to enhance production using Industry 4.0 principles, Al, and the latest technology," says Zafar Iqbal. "We’ve now developed a method for handling longer fibers that improves yarn consistency, end-product performance, and cost efficiency, while reducing waste. Our ongoing partnership with Trützschler continues to drive innovation and efficiency in our operations."

TC 30Si is here to help...
Ibrahim Fibres wanted to process 51mm polyester with 51 mm viscose fibers. In line with these requirements, Trützschler engineers optimized the TC 30Si carding machine for processing long polyester and viscose fibers. This machine is specifically customized for man-made fibers and can process these fibers more effectively due to its larger drum diameter, which results in a 14 % extended carding length. The machine also has 35 % more active flats. It has one licker-in and its cylinder, doffer wire, flat tops and stationary flats are all designed for processing man-made fibers.

"We chose TC 30Si for its advanced features, such as its 1400 mm cylinder diameter, extended carding lengths, and the automatic T-GO gap optimizer," says Zafar Iqbal. "These attributes support our Industry 4.0 goals by enhancing technology integration, data use, and operational efficiency, making it ideal for modernizing production and staying competitive in the textile industry."

And Ibrahim Fibres has even more reasons for choosing the TC 30Si: "It has user-friendly software and an intuitive Human Machine Interface (HMI), making it easy to maintain with minimal adjustments. This card boosts productivity and reduces energy consumption, while also improving consistency and reducing defects."

Mimaki: Printing on non-polyester materials

Polyester has been the cornerstone of the textile printing industry for decades. Its compatibility with the digital sublimation process—a cost-effective, simple technology—has driven exponential growth in polyester printing. However, the very characteristics that make polyester well suited for sublimation printing render this printing technique unsuitable for other materials, such as cotton and some blended fibres, leaving a significant gap in the market.

This gap was, until recently, partially filled by direct-to-textile printing. However, this method requires substantial initial investments in equipment and heavily relies on the time- and resource-consuming pre- and post-processing of fabrics to ensure colourfastness, colour accuracy, and compatibility with different substrates. Consequently, a need arose for a more sustainable and cost-effective solution that could cater to a wider range of textiles.

This gap was, until recently, partially filled by direct-to-textile printing.

Consequently, a need arose for a more sustainable and cost-effective solution that could cater to a wider range of textiles.

In response to this demand, Mimaki spent six years developing a breakthrough technology, TRAPIS, a simple two-step textile transfer printing solution, consisting of only an inkjet printer and a high-pressure calender. The design of choice is printed by the inkjet printer onto the company’s groundbreaking Texcol® pigment ink transfer paper. This is then transferred to the application via the calender.

Entirely removing the treatment stages means that printing on non-polyester materials has gone from an expensive and time-consuming task to one that is simple, cost-efficient and more sustainable.

Ideal for home textiles and soft signage which often require vibrant colours but varied materials, this technology gives printers the ability to print on a wide variety of materials, including natural fibres like cotton and silk without losing stretchability or colourfastness. All this can be done with just one type of ink, making the process flexible and adaptable to customer demands.  

The pre-treatment and washing of the fabric is often needed in digital dye printing, producing a significant amount of wastewater in the process. TRAPIS eliminates those stages altogether and is almost entirely waterless, saving around 14.5 litres per square metre of water, an almost 90% decrease in comparison to digital dye printing .

Additionally, this eliminates the need for wastewater treatment facilities, which can be both expensive and constrictive when it comes to where the solution is installed.

Monforts and Uniferro join forces at Febratex 2024

Finishing machinery specialist Monforts will exhibit at the upcoming Febratex textile machinery exhibition taking place in Blumenau, Brazil, from August 20-23, along with Uniferro, its new regional partner.

This new alliance follows the retirement of Herbert Erdmann of the service agency Euro Texteis, who has worked with Monforts over more than 30 years to secure a leading position in the region for Montex stenter dryers, Thermex dyeing ranges and associated finishing technology.

With offices in Sao Paulo and Ceara and sub-agents across Brazil, Uniferro has been active in the textile industry for over 50 years.

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

For single-sided application with paste or foam, the versatile coater is suitable for both incorporation into existing finishing ranges as well as installation with new Monforts 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 black-out coating.

Denim hub
Brazil remains a buoyant hub for textile manufacturing with a particular stength in the denim dyeing and finishing sector and many Monforts Thermex hotflue dyeing systems are already operational in the region, reaping the benefits of the Econtrol® process.

Econtrol® is a continuous process for the dyeing of woven cotton and cellulosic fabrics, especially denim, in which reactive dyestuffs are fixed into the fabric in a one-step dyeing and drying process with a controlled combination of steam and air. The entire pad-dry process takes just two-to-three minutes.

“Differentiation is the key in the highly-competitive denim fabrics industry, whether through the successful incorporation of new fibres, accommodating new fabric constructions or exploring the many options for how to treat them at the finishing stage, to gain a market advantage,” says says Monforts Regional Sales Manager Achim Gesser. “Our lines allow users to be extremely versatile and respond quickly to market demand, while also allowing very short production runs.”

Because finishing is a particularly energy-intensive part of the textile production chain, it is exactly where convincing results can be achieved, he adds, and Monforts has developed a wide range of energy-saving. These included a range of heat recovery systems, such as the Universal Energy Tower and the ECO Booster. Both can also be retrofitted to existing ranges to make production more resource-efficient and economical, yet without having to invest in a new machine.

“Energy costs tend to be high in Brazil and can account for up to 70% of production costs for our customers, so there is great demand for ways of saving money,” says Gesser. “Cutting energy usage also helps in terms of global warming and reducing carbon footprint, of course, so these latest technologies are a win-win for fabric finishers. As we look forward to a promising partnership with Uniferro in Brazil, we would like to extend our thanks and best wishes for the future to Herbert Erdmann for his hard work over the years.”

Tintoria Finissagio 2000 also focused on innovation when equipping a new stenter frame. The company opted for the latest development from German machine manufacturer Mahlo GmbH + Co. KG: the Orthopac RXVMC-20 automatic straightening system. The new straightening concept is specially designed for processing textiles with high distortion dynamics, i.e. textiles with highly variable distortion. Two individually controlled and driven straightening modules with a total of three bow and four skew rollers ensure that bow and skew distortions are corrected in small steps. The control concept is also new. A scanner group at the infeed of the straightener detects distortions even before they reach the correction rollers. This means that the rollers are brought directly into position and the fabric is corrected from the very first centimetre. A scanner group at the outfeed also recognises any residual distortion, which is then corrected on the second straightening module.

Recycled fibres: Swiss manufacturers for circularity

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

Faster and cheaper carbon fibre production with CarboScreen

Faster and more cost-effective carbon fibre production - the technology of the start-up CarboScreen comes a good deal closer to this dream. The founders Dr. Musa Akdere, Felix Pohlkemper and Tim Röding from the Institut für Textiltechnik (ITA) of RWTH Aachen University are using sensor technology to monitor carbon fibre production, thereby doubling the production speed from the current 15 to 30 m/min in the medium term and increasing turnover by up to €37.5 million per year and system. This ground-breaking development also impressed the jury at the ITMF at their Annual Conference in Keqiao, China, and was honoured with the ITMF StartUp Award 2023 on 6 November 2023.

Dr. Musa Akdere accepted the award on behalf of the CarboScreen founding team.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Both types of damage cannot be optimally detected by current means or only become apparent after production, to name just two examples. This leads to higher production costs. In an emergency, faulty production can even lead to plant fires. For this reason, and to ensure good production quality, the system is run at 15 m/min below its production capacity for safety reasons. However, 30 m/min or more would be possible. With the sensor-based online monitoring of CarboScreen, the production capacity can be doubled to 30 /min. This would lead to higher production, resulting in lower manufacturing costs and wider use of carbon fibres in mass markets such as automotive, aerospace and wind energy.

Südwolle Group and KARL MAYER GROUP cooperate to unlock the potential of merino wool

The KARL MAYER GROUP and the Südwolle Group have joined forces in a project to explore the possibilities of merino wool for warp knitting technology. The project was triggered by the increasing demand for textiles made from sustainable and environmentally friendly materials. The cooperation was to develop innovative fabrics from renewable raw materials for use in underwear and functional sportswear. The focus of the work was on the use of wool as a material with excellent comfort properties and the look and feel of lightweight single jersey goods. The natural fiber fabric qualities are not typical for warp knitting processing, so the challenges during the project work were diverse.

The natural fiber fabric qualities are not typical for warp knitting processing, so the challenges during the project work were diverse.

Merino wool yarns with good running properties
Regarding the choice of material, the product development team of Südwolle Group recommended the Hidalgo yarn from their product portfolio. The yarn was created using the in-house developed Betaspun technology, in which a filament was twisted around a merino core. When natural fibres such as wool, cotton or silk are combined with sustainable fibres such as biodegradable polyamide as the filament, the spinning process can create durable, lightweight yarns that disintegrate completely without residue after use. The yarns made from the two components also have good running properties for use in warp knitting. "The polyamide content of the yarn increases its tenacity, reduces hairiness and makes it an excellent choice for warp knitting technology," confirmed Gabriela Schellner from KARL MAYER's Textile Product Development Department.

Shape stability paired with single jersey "look and feel"
The Hidalgo yarn, which is made from merino wool, was processed on a warp knitting machine using a carefully thought-out lapping selection to produce a light, soft fabric which, above all, retains its shape. The textile specialists at KARL MAYER had experimented with two different single bar fabric qualities beforehand and had thus adopted a new approach for jersey machines.

The first results are promising. Now more trials are needed to perfect the technique. Development partners are needed, including fabric producers, brands, and garment manufacturers, with whom the fabric qualities, machine equipment and orientation to the end applications can be refined. The KARL MAYER GROUP and the Südwolle Group are also unanimous in their desire to push the boundaries of what is possible with merino wool and knitting technology and to develop new solutions for the textile industry through further project work.

Discussing the event’s potential, Mr Le Hoang Tai, Deputy Director General of the Vietnam Trade Promotion Agency (VIETRADE), said: “Vietnam is one of the world’s leading textile producers and exporters, and going from strength to strength as one of Southeast Asia’s manufacturing hubs. Our establishment has many years of experience organising trade fairs throughout Vietnam, and together with Messe Frankfurt we are excited to help international fairgoers unlock the potential of the country’s fast-growing textile market. In addition, Ho Chi Minh City’s accessibility, and Vietnam’s proximity to other leading textile-producing nations such as Bangladesh, Cambodia, China and India, make it the logical venue to host an event of this nature.”

Many international textile manufacturers have been expanding operations into Vietnam, augmenting an already strong domestic industry. According to the Vietnam Textile and Apparel Association (VITAS), the country’s textile and garment industry achieved staggering annual growth of 20 – 26% from 2018 – 2022. Participation in international trade agreements such as the Regional Comprehensive Economic Partnership (RCEP), the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), the EU–Vietnam Free Trade Agreement (EVFTA), and the Indo-Pacific Economic Framework for Prosperity (IPEF)[2], bodes well for future growth.

As one of the world’s biggest importers of textile machinery, and a consistent importer of fabrics, yarns and fibres, garment production is the cornerstone of Vietnam’s industry. The country utilises cotton and functional materials to produce casualwear, childrenswear, swimwear, workwear, and much more, with sportswear an especially fast-growing category, and high-utility garments expected to achieve high exports.

By linking textile players from across Asia, Europe and beyond with this market, VIATT 2024 is willing to play an important part in shaping the future of Vietnam’s industry. Next year’s fair will host an extensive mix of international and domestic exhibitors covering multiple textile sub-sectors, including garments, apparel fabrics and accessories, yarns and fibres, digital printing, home textiles, technical textiles and nonwovens, textile processing, textile machinery, and more.

EREMA presents a new solution for PET fibre-to-fibre recycling

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

The transfer printing method is more sustainable than both analogue and digital textile dye printing methods with zero water consumption and substantially lower CO2 emissions. The system comprises three essential elements: the Textile Pigment Ink, the Transfer System and the Textile Pigment Transfer paper, Texcol®.

Texcol® is a transfer paper pioneered by Dutch paper manufacturer, Coldenhove that allows for transferring a digital print using an environmentally friendly 3-step transfer process to create a vibrant application on a wide range of materials, including natural fibres. The design is initially printed onto the paper using a customised TS330-1600 - Mimaki’s high-volume, high-quality dye sublimation printer - and Mimaki’s new pigment inks developed for the process. The module that adapts the TS330-1600 will be available as an option for existing and new Mimaki customers in Q3 2023 but is being previewed on the Mimaki stand at ITMA.

Mimaki’s new Textile Pigment Ink is undergoing bluesign certification before commercial availability. bluesign is a renowned certification programme that ensures the highest levels of safety, environmental friendliness, and sustainability within the textile and apparel industry.

As the final stage, the Texcol® paper undergoes a one-step waterless process, through an entry-level calendar machine onto the textile of choice.

Cyclical textile technology
Mimaki is also debuting its new, unique Neo-Chromato Process, which revolutionises the reuse of coloured polyester textiles.

By decolourising polyester textiles that have been dyed using dye sublimation technologies, this innovative process allows materials to be re-printed or dyed immediately, contributing to a smaller circular economy. There is no limit to how many times reused polyester can be treated with the Neo-Chromato Process and the process itself minimises water usage and pollution by enabling the disposal of the absorbent paper and decolouring solvents used in the process as burnable waste.

ITM at JEC 2023

From April 25th to 27th, 2023, the Institute of Textile Machinery and High Performance Material Technology (ITM) of TU Dresden will be exhibiting at the pavilion SAXONY! at JEC World 2023.

The ITM will provide a comprehensive overview of its current research in the field of machine and product development along the entire textile process chain.

The upcoming JEC 2023 exhibition will highlight innovative Customised Connective Cores (CCC), which are custom-made core-insert structures additively manufactured using cellular metal and a form-fit integrated insert. These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

This breakthrough opens up new possibilities for fastening lightweight panels.

Another highlight at the exhibition is the repair process for fibre-reinforced composites (FRP) developed at the ITM. Instead of mechanically grinding the damaged area, the matrix in the repair area is locally dissolved using a UV-rays-induced depolymerisation process. Damaged fibres can thus be replaced by a customized repair patch. Free yarn ends on the textile repair patches are spliced with the UV-exposed yarn ends in the repair area using an adapted splicing process. In this way, a very clean, simplified and mechanically improved repair area can be achieved compared to the state of the art.

The diverse possibilities offered by the structure and process simulation of textile high-performance materials and textile manufacturing processes will also be presented. By means of multi-scale modelling and simulation, a profound understanding of materials and processes is achieved at the ITM. Finite element models on the micro, meso and macro scale have been developed and validated for this purpose. Examples from current ITM research projects demonstrate the various possibilities and areas of application of modern simulation methods in the field of textile technology.

Moreover, an innovative process for the integral manufacturing of 3D rib-stiffened preforms with complexly arranged stiffeners in 0°, 90° and ± 45° orientation was developed and successfully implemented at the ITM. Due to the process-integrated structure fixation and the continuous fibre reinforcement between shell and rib structure, the 3D preforms are perfectly suited for the production of highly load-bearing FRP components with increased bending stiffness, which will be exhibited at JEC. Hence, the lightweight construction potential of high-performance fibres can be fully exploited.

A successfully established development are partially flowable 2D textile reinforcement fabrics that are continuously manufactured in one single process step. For this purpose, the entire process chain was developed at the ITM, which allows a cost-effective and high-volume production of load-bearing thermoplastic 3D FRP components with continuous fibre reinforcement between shell and stiffeners.

At JEC 2023, the ITM will also present a partially embedded textile latice girder as reinforcement for carbon concrete applications, which was produced by means of an innovative textile manufacturing process based on the multiaxial warp knitting technology. Through the development of a customized warp insertion, manipulation and take-off system as well as appropriate shaping methods, it is now possible to produce tailored textile semi-finished products, e.g. for use in wall and ceiling panels. These textile latice girders represent a resource-saving alternative to conventional steel girders due to the reduced among of concrete required and the additional cavity for media and cable guidance.

The integration of textile actuators and sensors in FRP provides structures with additional functionalities. The research and application of such interactive FRP with different matrix materials (e.g. with thermoset, elastomer or concrete matrix systems) for structural health monitoring or adaptive systems is one of the key research areas of the ITM.

Moreover, the development and implementation of innovative yarn constructions based on recycled high-performance fibres (e.g. rCF, rGF, rAR) for sustainable FRPs is successfully promoted at ITM. By use of a special carding machine, recycled fibres are opened up, separated and joined to form a wide, uniform ribbon. Subsequently, innovative hybrid yarn constructions made of evenly mixed recycled high-performance and thermoplastic fibres with variable fibre volume fractions can be manufactured by means of various spinning technologies. Selected yarn constructions and components will be showcased at JEC.

Mahlo at the INDEX 2023: Nonwovens in focus

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, Mahlo GmbH + Co KG awaits trade visitors from all over the world to inform them about the right measurement technology enabling more efficient and high-quality production of nonwovens.

With a wide range of sensors, different measuring techniques and the corresponding measuring bridges, practically all tasks regarding the control of basis weight, moisture, thickness, fibre content, and air permeability can be solved in a cost-efficient and practical way.

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, Mahlo GmbH + Co KG awaits trade visitors from all over the world to inform them about the right measurement technology enabling more efficient and high-quality production of nonwovens.

With a wide range of sensors, different measuring techniques and the corresponding measuring bridges, practically all tasks regarding the control of basis weight, moisture, thickness, fibre content, and air permeability can be solved in a cost-efficient and practical way.

As an example, Wulbeck mentions spunlace products. They mainly consist of fibres such as cotton, PE, PET or rayon. They absorb light in the near-infrared range. Water and all other materials have different spectral ranges and can thus be distinguished. The near-infrared sensor Infrascope NIR determines the moisture content and the basis weight of different materials by attenuating the light in certain wavelengths. Due to its very high spectral resolution, the sensor can distinguish between components with very similar but not identical IR absorption and achieves high measurement accuracy. "Up to 0.05 g/m2 of the respective coating weight is possible," says Wulbeck.

"We want to support manufacturers in optimising their production processes and thus also the end product," says Matthias Wulbeck, Mahlo product manager for QCS. Because, like many other industries, the nonwoven sector is struggling with challenges such as rising prices for energy and raw materials, long delivery times and uncertain supply chains. In order to continue to produce economically and on time, it is therefore necessary to save resources and avoid faulty production as well as unnecessary process times. "Our Qualiscan QMS measurement and control system helps to do just that."
