From the Sector

After four decades in the packaging industry, the Manjushree Group is entering the Indian nonwovens market. The entrepreneurs rely on a flexible RF Smart Composite line from Reifenhäuser Reicofil to meet very different customer requirements.

The Manjushree Group operated a blown film line for packaging materials for the tea industry in the eastern part of India as early as 1983. In the years that followed, Manjushree Technopack Ltd. developed into one of the largest suppliers of solutions for rigid plastic products in South Asia - and the family business grew into a group with several business segments. In 2018, the entrepreneurial family repositioned itself: it sold its previous core business to a financial investor and established Manjushree Ventures with footholds in start-up financing, real estate business, and manufacturing - the largest of which is Manjushree Spntek as a producer of high-quality spunmelted fabrics.

Since February 2023, Manjushree Spntek has been producing high-performance spunmelts on an RF Smart Composite line from Reifenhäuser Reicofil - benefiting both from many years of experience in the packaging industry and from experience with Reifenhäuser's blown film lines. "We know a lot about plastic extrusion, for example when it comes to line operating parameters such as temperature and pressure. Processing is similar in both industries," explains Rajat Kedia. "The main difference is the distribution of the products: In plastic packaging, we had an established customer base and sold a lot of material to the big consumer goods manufacturers. The nonwovens market in India, on the other hand, is still forming, with thousands of small companies currently getting involved." These serve customers in their regions, such as hospitals.

The RF Smart Composite line is a standardized spunmelt line for smaller and emerging markets. The line produces nonwovens of the highest Reicofil quality with appropriately adapted throughput. This makes it ideally suited for applications in hygiene and medical technology and, with typically 8,200 annual production hours, it is extremely reliable. In addition, operators can start production quickly because in many cases the line can be integrated into existing buildings.

Before production could start, Manjushree built a new production building in Bidadi, a town an hour's drive from Bangalore International Airport. The building is designed to be sustainable: It uses natural light and fresh air, has comprehensive contamination control, and obtains almost all of its energy from renewable sources. Reifenhäuser Reicofil then installed, commissioned and tested the RF Smart Composite line.

Since February 2023, Manjushree Spntek has been producing high-quality spunmelted nonwovens, including ultra-soft fabrics and fabrics with special coatings for customers in the hygiene and medical industries. The material can be used, for example, for baby diapers and feminine hygiene products, but also for medical articles ranging from surgical gowns to surgical drapes.

Monforts will be presenting its finishing technologies at the forthcoming Igatex textile machinery exhibition, which takes place from December 1-4 at the Lahore Expo Centre in Pakistan.

The importance of the textile industry to Pakistan’s economy cannot be overstated – it accounts for 60% of the country’s overall exports and some of its industry’s players are very major employers. In the year to June 2022, Pakistan’s textile exports climbed by 25% to a record value of $19.3 billion according to the country’s Bureau of Statistics, as security of deliveries – especially to Europe and the USA – worked in the country’s favour, in the light of the Covid-19 pandemic and subsequent supply chain issues. It has a key role to play in quickly getting the country back on its feet after the devastation.

Monforts customers in the regions around the country’s three biggest cities of Karachi, Lahore and Faisalbad include all of the main players in the fields of home textiles and denim production, including Afroze, , Al Karam Artistic Milliners, Azgard-9, Crestex, , Gul Ahmed, Interloop, Liberty Mills, Lucky Textile Mills, Mustaqim, Naveena (NDL), Rajby Industries, Sapphire Finishing, Soorty, Style Textile and US Denim.

These companies rely on established Monforts technologies including Montex stentering equipment, Monfortex sanforizing units and Thermex dyeing ranges. The company’s Matex Eco Applicator minimum application system has also proved a big hit in recent years.

Monforts has also achieved considerable success in Pakistan with its Econtrol®* dyeing system  – an effective and established dyeing process. More than 40 Thermex continuous dyeing ranges have been installed in Pakistan in recent years and operator training on the Econtrol®* process by sophisticated technologists is an additional service.

The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step. Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

An immediate wash off is also unnecessary, allowing for flexible production planning. The process is suitable for pale to dark shades with very good fastness properties. Also waste water treatment is improved by this technology.

*Econtrol is a registered mark of Dystar Colours Distribution GmbH.

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

1. Intense Needling
   Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
   Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

Digitalization is a big story in the world of business. It’s all about change, making use of technology to transform attitudes and create new opportunities to grow revenue. At its heart is innovation, with new systems and intelligent use of data. In textiles, the entire value chain is going digital, as evidenced by the commitment of Swiss Textile Machinery Association member firms. Their story – presented here in six ‘chapters’ – spans industry sectors through spinning, weaving, finishing and nonwovens.

Cost savings and more
The process of digitalization in the textile industry today is continuous – faster in some segments than others – but noticeable everywhere. Automation is promising in many areas of finishing and making-up, where initial investments are being made. An example is folding of finished goods, previously a slow manual operation. Now, high-performance automatic folding machines from Swiss company Espritech deliver the potential for cost savings, unlocking new options for positive change at this most labor-intensive stage of production. For manufacturers in low-cost areas, the benefit results from its volume and is a simple financial one. In higher-cost segments, the application of this technology can be part of a completely new business model, taking production closer to the end customer.

Better process, better workplace
Pioneering in the field of digitalization embraces social responsibility along with the introduction of bold new technological innovation. That’s a commitment made by Uster, as it aims to shape future working practices in the textile industry in areas where its systems are applied. In fabric inspection, that means combining the strengths of human capabilities with the performance of Artificial Intelligence. Automatic defect classification with machine learning technology is the next leap in digitalization for fabric manufacturers, following on from automated detection of fabric faults, which is already well established in weaving and finishing mills. This will bring benefits in profitability for the manufacturer – as well as an improved working environment for their operatives, freed from repetitive tasks.

Information, flexible and fast
Access to data is critical in the digitalized world of textiles. It must be flexible, fast and secure, and available to all levels of the company – worldwide. Jakob Muller serves the narrow fabrics industry ideally with a digitalization portal, perfectly developed to provide essential production information. The portal is a browser-based production data acquisition system, with direct access to the machine controls. The system offers unique data monitoring and communication on a global framework. Digitized weave rooms present information 24/7 on desktops at the customer’s plant, as well as on tablets and smartphones remotely.

Making the most of it
Rieter takes advantage of latest digital technology to offer customers a unique experience. Their digital spinning suite helps spinners overcome their daily challenges and manage costs and efficiency more effectively. This all-in-one mill management system connects all the machinery, giving quick access to the right information and a holistic view, from bale to yarn. Users profit from full transparency, and are presented with recommendations based on long-standing experience and know-how. This is digitalization at its most practical, applied to allow spinners to make the most of their installed machinery.

Production, service, training – digital everything
As a solutions provider, Saurer puts digitalization at the core of business, integral to its technology offering to customers. Some latest examples include self-optimization of spinning machines, and a fully automated transport of cylindrical or conical cross-wound packages. These are automatically stored in an internal buffer system, for later feeding to subsequent processes. Of course after-sales service is also digital: the e-shop and machine information hub, together with the web-based training centre, ensure that knowledge is transferred to customers – turning employees into experts.

See the future system today
Autefa Solutions uses the concept of digital twinning, visualizing any real-world concept of a nonwovens line to make it easier for potential customers to grasp the idea. It’s also a big help for training and servicing needs. Most of all they digitalize important parts e.g. of a baling press line with perfectly interconnecting software tools. This is an excellent method for reducing commissioning times. Ordered bale presses reach technical readiness in the form of a digital twin, before they are commissioned in the real world. This typically halves the total time to get the line up and running.
Speaking on behalf of Swiss Textile Machinery Association members, André Imhof, CEO of Autefa Solutions Switzerland AG, says: “Making digitalization our friend opens doors for business model innovations, which is essential for our industry competitiveness. The approach is to digitalize everything that can be digitalized. We won’t stop.”

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.
