From the Sector

Fong’s Europe will showcase the advanced features of its THEN Smartflow TSF at ITMA 2023.

These include the machine’s smart fabric transport system which ensures extremely even dyeing of the fabric through accurate control of the nozzle pressure and pump power, with movement through the machine via an PLC-controlled plaiting system and variable chamber adjustment depending on fabric characteristics.

The machine is equipped with a heat exchanger enabling it to heat the dyeing liquor quickly and efficiently, to reduce energy consumption. Its bath preparation unit and chemical dosing system ensure accurate and precise dosing of chemicals, dyestuff and salt, reducing chemical waste and optimising results while reducing process times.

The Smartflow TSF operates with a low liquor ratio of down to 1:2.5 with full loading of synthetic fabrics, which means that it requires less water to dye a given amount of fabric compared to traditional dyeing machines. This not only reduces the consumption of water and steam, but also the amount of wastewater generated.

The machine's control panel is easy to use, allowing operators to programme and monitor processes with ease.

Mimaki Europe, a provider of industrial inkjet printers, cutting plotters, and 3D printers, has announced the introduction of two technologies at ITMA 2023: a Textile Pigment Transfer Printing System and the Neo-Chromato Process. These innovations are showcased for the first time, and ahead of commercial availability, at the exhibition in Milan, Italy, solidifying Mimaki's commitment to sustainable and environmentally friendly solutions in the textile printing industry.

Mimaki’s New Textile Pigment Transfer Printing System
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.

In the run-up to ITMA, VDMA is presenting an overview of the textile recycling technologies offered by member companies exhibiting at ITMA. VDMA and its members are committed to a responsible use of all resources used in textile production.

At ITMA 2023 in Milan from June 8-14, Fong’s Europe will introduce its latest THEN Synergy Airflow and THEN Airjetwin machines, which exploit the principle to provide high-quality, efficient and eco-friendly dyeing processes for a variety of fabrics.

“THEN introduced its first machines with Airflow technology in 1980 and since then we have had wide experience of pretreating and dyeing with Airflow transport systems on all kind of fabrics,” says Fong’s Europe Director of Sales and Marketing Richard Fander. “Our team of engineers has collected data on dyeing processes, results and consumption figures for years and constantly makes use of this accumulated know-how to optimise the processes of our customers.

“The THEN team understands Airflow dyeing processes and technology based on it guarantees the lowest liquor ratio on round shape machines. The transport of fabric by air reduces the liquor ratio compared to every kind of hydraulically driven transport system.”

He adds that while not every fabric can be dyed and treated on Airflow machines with the same handle and appearance as on hydraulic round shape or long shape machines, where it is applicable, it can lead to significant savings of up to 35% in water, 50% in salt, 20% in dyestuffs and 30% in process time.

The THEN Airflow dyeing machines have several features, including several parallel functions for reducing process time. The VPR system shortens the rinsing time and water usage and the robust and homogeneous spraying device in the nozzle ensures a uniform dyeing in the shortest process time. The very short liquor ratio also reduces the use of salt and chemicals.

Groz-Beckert will be presenting the latest innovations from its product area Carding to visitors at INDEX™23

The InLine card clothing series for the nonwovens industry will take center stage at the Groz-Beckert exhibition booth. A new and patented manufacturing process made the development of the innovative metallic card clothing series possible. It offers customers improved process reliability and increased uptime of the card. At the same time, the new process enables environmentally friendly and resource-saving production.

In addition to a controlled and precise hardening of the teeth, the wires are characterized by a reduced rib height and a completely scale-free surface. An exhibit at the booth will demonstrate what distinguishes the new process from the conventional production method and will highlight the differences between the new Groz-Beckert InLine card clothing series and its predecessor generation.

The first special geometry of the Groz-Beckert InLine card clothing series to be developed was the SiroLock™ plus worker and doffer wire. It impresses with a more effective fiber take-up, control and transfer. Augmented reality will allow visitors to experience the functionality and operating principle behind SiroLock™ plus at INDEX™23.

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.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its Hong Kong subsidiary SHIMA SEIKI (HONG KONG) LTD., will participate in the 40th Session of SPINEXPO in Shanghai, China from 12th - 14th April 2023.

At SPINEXPO, SHIMA SEIKI will offer visitors a choice between its "SDS®-ONE APEX4" apparel design system and its "APEXFiz®" subscription-based design software. Whereas SDS®-ONE APEX4 is offered as an all-in-one proprietary hardware + software package, APEXFiz® is subscription-based design software that can be installed on customers' individual computers. Both SDS®-ONE APEX4 and APEXFiz® software support the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes, replacing physical sampling and consequently reducing time, cost and material that otherwise go to waste. When a design is approved for production, knitting data is automatically generated for converting to machine data, allowing smooth communication for digitally bridging the gap between studio and factory. APEXFiz® thereby helps to realize sustainability while digitally transforming the fashion supply chain.

Also on display at SPINEXPO will be SHIMA SEIKI's "yarnbank®," an online web service for searching and viewing the latest yarns, developed with cooperation from yarn companies from around the world. Registered users can download yarn data for free, for use in fabric simulation and virtual sampling on APEXFiz®, avoiding the need to scan yarn on their own. By using yarn that is used in actual production, designers and apparel companies can furthermore rest assured that the simulations created using yarn from yarnbank® are not merely realistic images but accurate representations using yarn that can actually be purchased and used in production. With yarnbank®, the entire supply chain from yarn companies and apparel companies to knit manufacturers can be connected digitally.

SHIMA SEIKI will also display the latest collection of its knit samples, including WHOLEGARMENT® knitwear that is knit in its entirety on the machine without the need for linking or sewing afterward. Together with virtual sampling performed on APEXFiz®, WHOLEGARMENT® offers smart production for realizing a sustainable fashion supply chain.
