From the Sector

Just in time for ITMA 2023 in Milan, the flat knitting machine manufacturer STOLL has launched its new collection COLOR IN KNITTING. It holds a range of knitting techniques that were ideated for novel super fine machine gauges such as the E20.

In addition, STOLL reveals its internal design workflow, showcasing how digital software tools can speed up the design process. The core of this is k.innovation CREATE DESIGN. Through the utilization of STOLL’s jointly developed design software solution, k.innovation CREATE DESIGN, in collaboration with @KM.ON, the shape and structures of a garment, can be digitally created, allowing for its simulation before it is even knitted. The interfaces to various external 3D software tools, allow for a realistic representation of the garment facilitating faster design decisions. Once the virtual knits, made in the CREATE DESIGN software are ready for manufacturing, it will be send to a knitting technician for further processing in k.innovation CREATE PLUS, This significantly speeds up product development while reducing communication issues between designers and technicians.

Sustainability and responsible handling of precious natural resources were key factors driving the development of the latest trend collection, COLOR IN KNITTING. STOLL-knit and wear®, a technique that stands for seamless knitted garments, can play a significant role in reducing waste. In addition, fewer process steps are required in the production chain - with advantages for production efficiency.
For another highlight of COLOR IN KNITTING, the STOLL creatives have worked on imitating different yarn effects with knitting technology such as slub yarn optics or the simulation of fabrics like crepe de chine/crepe georgette

On the occasion of the 150th anniversary of STOLL, COLOR IN KNITTING features a selection of vintage pattern replicates. These patterns can be found in STOLL’s extensive sample archives in Reutlingen. It is impressive to learn that all these former fabric constructions can still be replicated today and also reinvented with todays machine features. This approach showcases the steep progression of technical advancements over the past 150 years.

STOLL´s latest trend collection culminates in the creation of an invaluable resource: the book “Color in Knitting: By Designers, for Designers”. This publication aims to cater to a diverse audience by presenting a comprehensive guide to designing with colors using various flat knitting technologies and will be presented in the chapter "Book release".

Mimaki Europe, a provider of industrial inkjet printers, cutting plotters, and 3D printers, is debuting the new Tiger600-1800TS, Mimaki’s most productive sublimation transfer printer, on its stand at ITMA 2023. This latest high-speed, compact and robust roll-to-roll inkjet printer has been designed to accelerate the analogue to digital transformation within the textile printing industry.

The Tiger600-1800TS boasts a maximum printing speed of 550 m2/h (143% faster than the previous model) owing to the renovated high-speed printhead and Mimaki’s proprietary image quality enhancement technologies. The printer’s size has also been halved compared to the previous system, with the paper mounting and winding system both located at the back of the machine. This smaller footprint enables customers to easily install multiple units to meet fluctuating demand, whilst also increasing overall production capacity.

A further environmental benefit of the Tiger600-1800TS will be the bluesign® certification of its MLSb510 series sublimation transfer inks. This certificate, expected to be awarded in June 2023, will provide assurance that these inks are of highest quality combined with due consideration for the safety of consumers and print operators, and environmental conservation, and therefore, contributing to the sustainability of the textile industry.

Mimaki’s expertise in developing reliable, easy-to-use and efficient solutions has also not faltered in the development of the Tiger600-1800TS. The printer’s ink tanks can be replaced without interrupting the printing process, minimising down time. Maintenance of the printer is also reduced with its roller paper feeding method eliminating the need for the application of adhesives onto a belt.

On June 1, EREMA hosted the EREMA Discovery Day focusing on the post consumer segment from a European perspective. Live demonstrations showcased the latest machine innovations for PET and polyolefin recycling.

The invitation was accepted by around 400 customers and partners, mainly from Europe, to find out about the wide range of recycling technologies for PO and PET plastic waste. The technology that was presented and explained by EREMA experts and guest speakers during lectures in the morning, could then be seen live in-action in the afternoon when the recycling machines were demonstrated in operation. A total of six innovative recycling technologies were on display: INTAREMA® TVEplus® DuaFil® Compact, INTAREMA® TVEplus® RegrindPro® + ReFresher, the COREMA® cascade extrusion system, a VACUREMA® Inline Sheet line equipped with new EcoGentle technology, the new INTAREMA® FibrePro:IV machine, and the PCU-
TwinScrew. These allowed visitors to witness their performance and the high quality of recycled pellets that they produce.

"This wide range of technologies is necessary because the recycling process each of our customers choose depends on the type of plastic, the level of contamination of the input material, and which product will be made using the recycled pellets. Following the expansion of our Ansfelden site and with the new site nearby in St. Marien, we can now demonstrate all these processes, carry out test runs with customers' material and focus on development work independently of our Customer Centre," says EREMA's Managing Director Markus Huber-Lindinger.

EREMA is driving forward research and development work in the company's new R&D Centre. Two halls with a total area of 1,550 square metres and a new office building offering space for 50 workplaces has been built. Here, the company bundles cross-departmental test machines and laboratory facilities for post consumer and inhouse recycling applications. R&D is decentralised at EREMA. Employees from different departments handle process engineering challenges, innovations in mechanical engineering and automation technology - all with the aim of meeting customer requirements and achieving the highest possible quality of recycled pellets.  

On the evening before Discovery Day, EREMA celebrated its 40th anniversary together with customers and partners. A review covered the company's history - from the first workshop in a garage in 1983, to its position today as a innovation pioneer and one of the market leaders.

From April 25^th to 27^th, 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.

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.

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.

DiloGroup will be attenting India ITME 2022 (December 8 – 13, 2022), an exhibition for the textile industry, which offers a central forum for dialogue within the textile production sector, including textile machine building, fibre production, ancillaries and accessories. For DiloGroup this event is a good oppportunity to inform customers and interested parties about new developments aimed at improving production technologies with a focus on needlefelts.

Focal points of the development work are:

1. Intense Needling:
   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.
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. It is also suited for 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.
