Fibre Extrusion Technology Limited (FET) has been awarded £50,000 of grant funding to collaborate with the University of Manchester on complex spin pack and spinneret designs. This funding will provide FET with access to the expertise of four universities and the National Physical Laboratory to develop the next generation of machinery.

The grant is awarded by a consortium led by AMPI (The Advanced Machinery and Productivity Institute) and NPL (The National Physical Laboratory). AMPI’s Innovation for Machinery (I4M) programme supports businesses in West Yorkshire and Greater Manchester as part of an overall initiative to drive innovation for the UK’s advanced machinery manufacturers to meet the challenges of developing new technology and entering emerging markets.

In this project, FET will be working with the University of Manchester to conduct computational fluid dynamics (CFD) studies on a number of complex spin pack and spinneret designs. The aim of this work is to identify areas of improvement for FET’s spin packs and spinnerets and to use computer aided designs to develop significantly more efficient versions. The goal is that the research will improve the throughput of FET extrusion systems, thus reducing the amount of polymer lost through inefficient flow paths. This development, in turn, will reduce the environmental impact of synthetic polymer processing.

FET designs, develops, and manufactures extrusion equipment for a range of high value textile material applications worldwide. Established in 1998, FET’s major strength has always been to collaborate with customers in testing, evaluating and developing high value materials with diverse, functional properties. Efficiency and sustainability are key, so enhanced development of spinneret technology will contribute significantly to these objectives.

This year’s edition of ITMA ASIA + CITME proved to be a success for the exhibiting VDMA member companies. Measured by booked square metres, Germany had the largest contingent, among the foreign exhibitors. More than 40 VDMA member companies were exhibiting their innovative products in Shanghai.

Dr. Janpeter Horn, chairman of the VDMA Textile Machinery Association noted: “Although facing a difficult market situation, this year’s edition of ITMA ASIA + CITME has exceeded the expectations, both in terms of the number of visitors and the quality of the talks. The significant number of foreign visitors to the fair was particularly pleasing.”

Solutions were demonstrated for more sustainable textile productions by most of the exhibitors, and here the VDMA members presented their technologies for saving water, energy and raw materials under the heading “Smart technologies for green textile production.”  

Dr. Uwe Rondé, CEO, Saurer Intelligent Technology AG explained: “Saurer is satisfied with both the number of visitors and the quality of the discussions. Our booth was full from morning to evening with customers focused on latest technologies within the three mega trends: recycling, automation and digitalisation. Although machine utilisation in the spinning mills is still well below average, people are already gathering information and thinking about what to invest in once the market recovers.”

Benjamin Reiners, owner of Reiners + Fürst stated: „This year’s ITMA ASIA + CITME has exceeded our expectations by far. Especially the first day - a Sunday - has brought many high-quality customers and exclusively decision makers to our booth. We estimate about 20% international customers mainly from Bangladesh, Egypt, India, Iran, Pakistan, Uzbekistan and Vietnam. All customers agreed that the market situation at the moment is difficult, capacity usage is between 50-75% in the ring spinning sector and improvement is expected not before the 2nd half of 2024. Nevertheless the general spirit is very positive.“

“This ITMA ASIA was a great success for Trützschler. We welcomed a large number of Chinese visitors to our booth, as well as a significant number of interested international visitors”, said Dr. Bettina Temath, Head of Global Marketing Trützschler Group SE.

Georg Stausberg, CEO of the polymer processing solutions division and chief sustainability officer of the Oerlikon Group stated: „We can look back on a successful show where we were able to meet many of our customers not only from China, but also from Pakistan, India and Indonesia, for example.”

“A very well-attended trade fair, with interesting discussions, great innovative topics, in line with the modern and rapidly developing China" noted Wolfgang Schöffl, head of product line weaving machines and member of the extended management, Lindauer Dornier.

The VDMA Textile Machinery Association and VDMA China were present at the fair, to support the members e.g. with regard to IPR. With the help of a VDMA expert and a contracted law firm, the member company Sahm submitted a complaint application for patent infringement disputes during the exhibition to the onsite IPR office. Both parties, Sahm, and the Chinese company, that used patented design without permission reached an agreement: The Chinese company had to stop displaying functions and designs involving patent infringement on site which meant the removal of some structural parts and the covering of key components protected by patent protection.

Dr. Harald Weber, managing director of VDMA Textile Machinery concluded: “Asia, and China in particular, represent the primary foreign markets for the VDMA member companies in the sector. The Chinese market is the main destination for their exports. Other major export destinations in Asia include India, Pakistan, Bangladesh and Uzbekistan. ITMA ASIA + CITME provides a unique platform to showcase technologies for customers directly in Asia. The VDMA member companies are looking forward to the coming edition of the fair from 14 to 18 October 2024 in Shanghai.”

The latest survey of VDMA members' subsidiaries in China gives reason to hope that the economic situation in the Chinese textile industry could also improve significantly in the second half of the year. In addition, European textile machinery manufacturers are urged to be present on the most important market and at the trade fair and to offer Asian customers most advanced technology for their demanding challenges.

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK is celebrating a year of achievements since its new Fibre Development Centre was first opened. This period has shown a marked acceleration in the number of client technical trials conducted, involving the ever-increasing development of new polymers.

FET designs, develops and manufactures extrusion equipment for a range of high value textile material applications worldwide, offering melt spinning, wet spinning and spunbond/meltblown options. Since its inception in 1997, a major part of FET’s service portfolio has always been to collaborate with industrial and research establishments in testing, evaluating and developing high value materials with diverse, functional properties. FET’s previous Process Development Laboratory presided over the development of about 60 new polymer types in multifilament, monofilament and nonwoven formats.

Since the new Fibre Development Centre came on stream, this process has accelerated and the number of new polymers has now increased to over 70, with considerably enhanced facilities more than doubling capacity and increasing efficiency. Clients frequently spend several days on site participating in development trials and technical sales meetings, so the new Centre is designed to make their stay even more efficient and comfortable.

With more new trials booked for the rest of the year and well into 2024, it is expected that many more new polymers will be developed, with sustainable fibres leading the way.

Technological progress often results from close collaboration, and industries that rely on continual improvement stand to benefit from the return to in-person business. Cinte Techtextil China’s first edition since eased pandemic measures is set to reflect a 27.9% increase in exhibitor numbers, with a rejuvenated international contingent further supplemented by the return of the European Zone.

In its latest project it has further introduced BioHome3D – the first 3D-printed house made entirely with bio-based materials developed in a partnership with Oak Ridge National Laboratory. The 182-square-metre prototype features 3D-printed floors, walls and roof which are fully recyclable and highly insulated with 100% wood insulation and customisable R-values. Construction waste was nearly eliminated due to the precision of the printing process.

Riri, which became part of Oerlikon Group on March 1, presents its FW 24-25 collection, which embraces plastic and metal trends.

Metal Trends: GALACTIC SHINE, TEXTURIZED BLACK and AMBER GLAZE
As a result of joining the Oerlikon Group, specializing in surface engineering, polymer processing, and additive manufacturing, Riri is accelerating its transition to new processes related to surface treatments, particularly the PVD (Physical Vapour Deposition) technology, a physical process that significantly reduces impacts on the environment. PVD processes can be appreciated particularly on sliders and buttons where gold and shiny black finishes stand out. Silver textures, science fiction-inspired surfaces and shapes, and glossy, brushed finishes in shades of gray and very light gold: GALACTIC SHINE brings to earth a sidereal experience, witness from a journey where the atmosphere becomes rarefied and elegance takes shape among metalized leather tapes, gold PVD pullers, organic cotton, and gleaming inox. Black also shines in the TEXTURIZED BLACK selection, in tone-on-tone contrasts that create plays of light and shadow, thanks to metallic effects, glossy black PVD treatments, tapes and galvanic in shades of black. The atmosphere becomes warmer by varying on amber tones, the absolute protagonists of the AMBER GLAZE mood, which offers a different interpretation of elegance through bright amber tones, rose gold, diamond prints and geometric patterns.

Plastic Trends: GHOSTLY ICE and SPRAY VANISHED
GHOSTLY ICE features accessories that refer to the skiing theme, offering an algid beauty made up of transparent surfaces and icy effects, a theme in which the sustainability of mono-materials coexists with the elegance of the end result. The color inspirations are totally different, but sustainability and elegance remain unchanged in the SPRAY VANISHED zipper selection, in which vibrant multicolored effects communicate joy and vitality through iridescent PVD effects and the use of recycled materials, such as the polyamide of the patented B.Lock button.
