From the Sector

The Chairman of the Walter Reiners-Stiftung foundation of the VDMA Textile Machinery Association, Peter D. Dornier has awarded prizes to three successful young engineers. The award-winning works provide practical solutions on the topic of circular economy. For example, the recycling of carbon fibres, which are used to produce lightweight components for the automotive industry. Or the environmentally friendly production of yarns from crab shells. Another topic was medical applications: The processing of ultra-fine yarns into stents for aortic repair. The award ceremony took place online on 9 November as part of the Aachen-Dresden-Denkendorf International Textile Conference.  

With a creativity prize, endowed with 3,000 euros, the foundation honoured the diploma thesis of Irina Kuznik, TU Dresden. She used a creative approach to realise solutions for processing chitosan into fibre yarn.

Mr Kai-Chieh Kuo was awarded the diploma/master's thesis promotion prize of 3,500 euros. With his master's thesis, which was written at RWTH Aachen University, Mr Kuo contributes to the production of vital components used in medicine. The stents made of ultra-fine yarns are made possible by an innovative modification of the classic tube weaving process.

The Walter Reiners Foundation rewarded the doctoral thesis of Dr. Martin Hengstermann with the promotional prize in the dissertation category, endowed with 5,000 euros. The thesis deals with the production of recycled carbon fibres. These can be used to produce lightweight components for motor vehicle and aircraft construction or the wind energy sector.

New Prize Sustainability / Circular Economy
The environmental conditions of the textile industry and machine construction are changing. Topics such as climate protection and the circular economy are becoming central. From this perspective, the board of the Walter Reiners Foundation has decided to further develop the foundation's prize system.

In 2022, the foundation will for the first time offer a prize with a focus on design / sustainability. Peter D. Dornier, Chairman of the Foundation, explained: "Already in the design phase, one can set the parameters so that a textile product can be reintroduced after use into the economic cycle for a high-quality application. For example, through the appropriate use of materials and finishing. We are looking for solutions for resource-saving design, technology and manufacturing processes."   

Hexcel announces its latest HexPly® XF surface technology that reduces shell manufacturing time within the wind blade surface finishing process. HexPly XF increases overall blade manufacturing efficiency by reducing time in the mold by up to two hours and by banishing surface defects that require rework before painting.

Hexcel’s HexPly XF surface technology has been formulated to address the limitations of current blade shell surfacing techniques whereby pinholes and other surface defects have to be repaired by hand to achieve the perfectly smooth surface required for painting.

HexPly XF surface technology introduces a new material format as the surface finishing layer, eliminating the need for a traditional in-mold gel coating process. HexPly® XF for infused rotor blades, is a lightweight non-woven semi-preg construction, comprising an epoxy resin matrix, that co-cures with standard epoxy infusion systems. The product has a successful track record in prepreg blades and has now been adapted for infusion processes.

Easy to handle and supplied in a ready to use roll form, HexPly XF can be quickly applied by hand or with semi-automated layup equipment. It features one self-adhesive, surface finishing side - indicated by a removable protective foil. This side of the prepreg is placed against a release agent treated mold surface. Once the material has been positioned, the lay-up of the blade shell structure can start immediately, and the laminate can be infused. After curing, the blade is de-molded with the manufacturer benefitting from a pinhole-free surface that needs minimal preparation before painting.

HexPly XF material is less than half the weight of a typical gel coat per square meter, reducing the overall weight of the blade. Additionally, the consistent areal weight and thickness of the prepreg film provide a completely uniform surface coating, ensuring blade weight distribution and balance are maintained, which is critical as rotor diameters continue to increase. With no need to handle or mix liquid chemicals as in the gel coat process, HexPly® XF also improves the health and safety working conditions on the shop floor.

The material has a shelf life of six weeks at ambient temperature, which also minimizes cold storage requirements and helps to reduce scrap.

• Circularity at the centre

PG DENIM, the designer project by Paolo Gnutti, is ready for several important events scheduled for the autumn with ground-breaking interpretations and a new – increasingly green – business model. The occasion is its participation in the Blue Zone at Munich Fabric Start (Munich, 3-5 September 2019), a space which is increasingly often reserved for companies and projects with a high innovation rate in the world of denim.

PG DENIM at the German exhibition will be presenting important product innovations, but most notably new concepts developed for the S/S 2021 season. The focus here is on circularity, seen from a dual perspective: the product with the no longer traditional alternation of seasons, and a sustainabilityoriented approach.

Seasons meet

The new PG DENIM approach is geared towards overlapping seasonality, with less and less marked separations between projects dedicated to the spring-summer and fall-winter lines. The collections by PG DENIM can thus be increasingly defined as a “mix of products without seasonality”. Its focal points are innovation alongside the concept behind the initial idea, as opposed to just the season. This trend, explains Paolo Gnutti, CEO and R&D Head at PG DENIM, is also due to registering the fact that seasonality – in terms of environment and trends – is changing at an increasingly rapid pace. As a response to this situation, the choice has been made to design new collections starting from macro-trends and presenting fabrics for garments which are “easy to wear”, suitable for both warm and cold temperatures, in a true melting pot  of weights and sizes.

The lines for the previous season are thus reintroduced and restyled playing with weights and sizes, within a range where flock meets ultra-light fabric bases, or where vinyl is combined with typically summer weights which shift the fabric towards the world of “paper” with crispy touches, resulting in extraordinarily lightweight and strong items at the same time. Also the GARAGE DENIM has been upgraded with fluid and smoothed touched for garments which are easy to wear and have a strong personality.

Partnership with The Denim Window

The PG DENIM season is also enhanced by its partnership in The Denim Window project, which has resulted in a limited series of Creative Capsule Collections, derived from the idea of bringing together companies which had already worked or were working together, trying to highlight – through small capsule collections – the best of what had already been produced by traditional businesses. This has resulted  in three trailblazing capsules, two of which designed in partnership by PG DENIM and companies the likes of M&J Group, Cadica and Greenwear. Several copies of these collections have been made to travel the world, and – after the official presentation in July – they will have a special corner, The Denim Window, in the Bluezone at Munich Fabric Start.

The “Circular Programme” and the five “Rs” of sustainability

Also the PG DENIM approach to accountability in production processes has been enhanced by implementing the “Circular Programme”. As part of our corporate vision, Italian-style production is combined with compliance with what have become known as “the five Rs”, that is to say key concepts underlying the design and manufacturing model: Reduce (everything you are not using), Repair (everything you can), Reuse (anything available to you), Recycle (all that is left), Respect (everything around you).

This is the philosophy underlying each individual process at PG DENIM, and leading to new specific programmes which have been its business focus over the past few months:

1) Reducing the environmental impact during the fabric dyeing phase in reaction and sulphurbased processes, where the use of chemicals has been reduced by 40%, water consumption by 50% and CO2 emissions by 60%, which has also resulted in better penetration and a better result in the crocking process. This has led to producing 10 new articles which will be launched on the market.

2) Recycling all waste from processing and after use, creating a range of garments where cotton is actually obtained from regenerating these two kinds of waste. In this regard, PG DENIM for now is the only company on the market able to process with a percentage of recycled product exceeding 60% of the total, whereas the average for this kind of manufacturing is generally about 35%.

As regards regular production, on the other hand, PG DENIM follows stringent international standards, including Dtox, Reach and Gots in all its processing phases, also using BCI cottons and the Organic Cotton Standard for raw materials. Last but not least, it was recently awarded the GRS (Global Recycled Standard) certification.

IPC, the Industrial Technical Centre with expertise dedicated to plastic and composite innovation, is presenting two prototypes on its stand: an intelligent motorcycle helmet and a multifunctional windturbine blade. "With these two prototypes, IPC demonstrates its ability to functionalize composites, particularly with printed electronic components. Live demos will be organized during the three days of the show on our booth," explains Bertrand Fillon, General Manager of Research at IPC. The helmet was manufactured in partnership with the technical and creative paper manufacturer Arjowiggins, and the wind turbine blade, with the CEA. These two demonstrators will also be exhibited in Germany at the LOPEC exhibition 2019 in Munich on 20-21 March.

IMPROVE THE USER EXPERIENCE
The objective is to add new features to improve the user experience, without impacting security. The motorcycle helmet is equipped with sensors and NFC communication functions. "Here, printed organic electronics are used in the helmet to allow remote temperature changes," adds Lionel Tenchine, Program Line Manager for "Technologies for Intelligent Products" at IPC. The helmet manufacturing process is based on the use of composites and the infusion process.

DETECTING POTENTIAL DAMAGE IN ADVANCE
Developing predictive maintenance is an important issue when it comes to avoiding sudden, serious accidents. A recent McKinsey study estimates that by 2025 it will save $630 billion for companies, for example. The wind turbine blade presented at JEC World detects potential damage that could occur on the blade structure beforehand, making it possible to carry out preventive repairs on the one-meter-long blade. Printed organic electronics are used in the demonstrator to integrate strain gauges and the temperature detection function.

Lectra has leveraged more than 10 years of experience in connected manufacturing to offer Versalis®, an innovative digital solution designed to cut leather without compromise on quality. Featuring a powerful automatic nesting system for overall improvements in efficiency, the fully automated solution enables automotive leather suppliers to cut costs, improve productivity and minimize waste while also establishing a pathway to value-added Industry 4.0 processes.

Currently, almost 90% of leather used for automotive applications is cut using manual die presses, which require designers to build a physical prototype and finalize the design through trial and error. Lectra offers a fully digitalized leather solution from prototyping to cut parts—when used in combination with Lectra’s 3D prototyping and pattern-making software, Versalis digital leather cutting solution enables a 12-16 week reduction in development and launch cycles for vehicle seating models.
During the leather-cutting phase, the latest release of Versalis LeatherSuite allows automotive leather suppliers to achieve up to 15% greater productivity. Lectra’s end-to-end automotive leather offering furthermore guarantees optimal uptime through an extensive worldwide support network of field engineers and technical experts.
"Lectra focuses on a consultative approach that allows it to fully understand the customer’s needs before building a solution comprising software, hardware, consulting, training, and after-sales support,” said Frost & Sullivan Industry Analyst Kamalesh Mohanarangam. "Lectra’s equipment is fitted with more than 200 sensors that predict failure and immediately report issues to its call centres. This product feature and service has resulted in 98% uptime and very fast mean time to repair."

Although digital leather cutting solutions are an investment, leather cutters and Tier-1 suppliers have begun to recognize the value of these products. On average, Lectra’s solutions help customers achieve up to 7% savings on leather compared to manual die-press methods by minimizing human error and variability in the cutting room. A benchmark test of leather trim cutting for door panels demonstrated a 3.5% gain in material made possible by Versalis’ superior nesting capabilities compared to the customer’s yield using manual nesting with die press machines, representing potential savings of €9 million per year.
Versalis is the fruit of significant R&D investment for the company, which has always made re-investment of capital a priority. As part of a transformational plan, Lectra spent more than €50 million in investments between 2011 and 2015. With Lectra’s new strategy focusing on supporting their customers’ transition to Industry 4.0 standards, Lectra will increase the share of revenues dedicated to R&D to 10% for the period from 2017 to 2019, representing a rise of about 50% between 2016 and 2019.
