ITA at the ITMA 2023: Smart Circular Economy - Digital, sustainable, individual

Viola Siegl Presse- und Öffentlichkeitsarbeit
ITA – Institut für Textiltechnik der RWTH Aachen University

Experience smart circular economy - digital, sustainable and individual at the ITA exhibition booths H3-B304 und H3-A207 at ITMA 2023 from 8-14 June in Milan.

We will show a digital ring spinning texturer for spinning fine yarns with high recycled fibre content and take you on the Walk4Recycling.

"ITA Aachen and ITA Augsburg are part of the ITA Group International Centre for
Sustainable Textiles. Experience our textile innovations at two exhibition booths,"
explains ITA Institute Director Professor Dr. Thomas Gries. "See our ring spinning
tester at booth H3-B304, which spins recycled fibres sustainably and individually in a
previously impossible fineness. In addition, there is digital yarn monitoring, which
enables new market potentials. Get an idea of the Recycling Atelier of ITA Augsburg
at booth H3-A207 and see the textile cycle from used textile to solution steps for
industrial implementation together with industry partners. Join us on the
Walk4Recycling and follow the path from used textile to a new knitted pullover on a
tour of the trade fair. This is how we live up to our claim as the ITA Group:
sustainable - digital - individual."

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of
fine yarns with high recycled fibres content

The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a
digital ring spinning tester on its stand in Hall 3-B304, which spins recycled fibres
directly and conventionally with a particularly high content of 60-70 percent. Up to
now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in
rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring
spinning of recycled yarns now enables the spinning of finer yarns and thus a higher
application level for recycled materials.
A unique selling point of the ITA ring spinning tester is the simultaneous spinning in
the direct spinning process from the sliver and in the classic ring spinning process.
For this purpose, the strength and elongation of the spun yarn are determined online
and digitally for the first time. The real-time measurement allows process parameters
and yarn properties to be adjusted iteratively and quickly.

The ring spinning tester was upgraded from an existing tester to Industry 4.0
standard and is operated via a tablet. Operation via tablet enables the adjustment of
process parameters including online quality monitoring remotely from anywhere in
the world. For this purpose, the ring spinning tester is also able to produce fine ring
spun yarns. These yarns made from recycled material opens up a multitude of further
fields of application for woven and knitted goods. Now, for example, clothing and
technical textiles can be made from recycled material, the production of which was
not possible before - such as outerwear made from recycled material. The
development of new industries and fields of application opens up new market
potential for recycled yarns - also and especially for processing in Europe. This
creates the opportunity to preserve key technologies and jobs in cost-intensive
locations.
Other exhibits such as a smart glove and a smart needle show you how the use of
sensors in machine components and wearables makes daily work easier. Smart
Glove, for example, is a smart glove based on polymer optical fibres and quantum
dots. The quantum dots can be programmed to detect hazardous substances and
trigger a fluorescent effect on contact that changes the glove's luminous colour. In
addition, we will show other recycling demonstrators in garments and technical
textiles on our two stands H3-A207 and H3-B304, demonstrating the range of uses of
recycled fibres. One example is a jumper made from 65 per cent recycled carbon
fibres and 35 per cent virgin polyester fibres, produced from post-consumer textile
waste with ring-spun yarn.

ITA Augsburg - Recycling Atelier: Walk4Recycling

The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH (ITA
Augsburg) on booth H3-A207 presents the textile recycling from used textiles into
new products via the various process steps and, together with the industrial partners,
opens up solution paths for industrial implementation.
Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used
textiles from used knitwear into a new knitted pullover via a ring yarn made from a
blend of 65 percent recycled cotton and 35 percent virgin polyester. The key
innovation here is the high proportion of recycled fibres from post-consumer textiles
for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality
textiles are spun from these materials. The industrial partners participating in the
Walk4Recycling are partners of the Recycling Atelier and contribute with their
technologies to the fact that fibre material from old clothes can be processed in
various process stages into a yarn of new value and high-quality ready-made
garments.

The Walk4Recycling offers visitors the opportunity to experience a complete
recycling cycle with the numerous process stages from tearing the old textiles,
preparing and spinning the fibres and knitting a new jumper live during the fair. Get
detailed information on the mechanical recycling of clothing via QR code, website
and flyer about the participating exhibitors and their machines and technologies. A
short movie will give you additional insights into the various processes involved in the
production of the jumper.
The ring spinning tester of the Institut für Textiltechnik of RWTH Aachen University
also processes the fibre mixture of recycled and new fibres during the fair and is thus
part of the Walk4Recycling.
With its knowledge of these processes and technologies, the Recycling Atelier offers
training courses and workshops on recycling and the circular economy, as well as
concept studies with prototype production, support in industrial implementation and
the development of new business models.

Please visit our booths H3-B304 and H3-A207 and join the Walk4Recycling
together with us - we look forward to seeing you!
