From the Sector

Monforts has installed and commissioned a new Montex finishing range at the Baltic Works of Halley Stevensons in Dundee, Scotland, to further boost the weatherproofing specialist’s highly flexible operations.

The range, with a working width of two metres, was built at the Montex assembly plant in Austria and consists of a Montex®Coat coating unit in knife execution for paste and foam coating and a Montex 8500 6F stenter.

Founded in 1864, Halley Stevensons has amassed unique technical know-how and manufacturing experience in the art of waxed cotton for weatherproofed fabrics and is able to provide international orders in custom colours and finishes to very low minimum quantities where required. The company exports worldwide and its premium brand customers include Belstaff, Barbours, Filson and J.Crew.

The range has replaced one of the company’s older stenter/coating lines and has already enabled Halley Stevensons to recreate various products with lower coating applications at higher speeds than was previously possible.

Waxed cotton was originally developed by sailors in the early 15th century when Scottish North Sea herring fleets began treating flax sailcloth with fish oils and grease in an attempt to waterproof their sails. Remnants of these sails were used by the sailors as capes to withstand the high winds and sea spray.

By the mid 1850s, sailcloth was being treated with linseed oil, but while initially highly effective, it would yellow and stiffen through weathering over time and eventually lose its waterproofing qualities.

In the years that followed, various treatments were applied to cottons in an attempt to find the most effective weatherproofing solution, and the combination of densely-woven cotton impregnated with a paraffin waxed coating proved most successful. For over 150 years, Halley Stevensons created many different variations of both woven constructions and finishing treatments and now supplies thousands of metres of waxed cotton every year, with each roll produced to custom specifications.

“The beauty of waxed cotton is its durability and longevity,” says Managing Director James Campbell. “The fabrics are breathable, with the wax adjusting to ambient temperatures to be softer and more breathable in warm weather and stiffer and more wind proof in cold conditions.”
While traditional waxes are petroleum or paraffin based, Halley Stevensons has always been comfortable about using a waste product from industry and reusing it to make products that last a lifetime.  

“We are always exploring different finishing techniques and one of our most popular finishes is our hybrid aero – an emulsified blend of waxes,” Campbell says. “This fabric is water repellent but has little wax in the mixture so the handle is much drier to touch than the traditional wet waxes.”

The company has also recently launched a new 100% plant-based wax – Ever Wax Olive – consisting of a blend of olive oil, rape seed and castor bean with comparable water repellence to petroleum and a far better rating than other natural waxes which have come before it.

“The high tradition of skills and fabric innovation imposed by our original guildsmen is still our benchmark standard of honest workmanship today,” Managing Director James Campbell concludes “We use responsibly sourced cotton fabrics and processes that are gentle to the product and low impact to the environment. Our dyeing methods use very low levels of water and our waxes are simply heated up for application and cooled down to store when not in use, meaning no waste discharges. Now, with this new Monforts line, we are also achieving running speeds two-to-three times faster than with the older stenter, combined with less gas usage. It’s proved a great partnership.”

The associations published a joint European textiles industry statement on the energy package claiming incisive actions with no further delay.
Here is the statement in full:

Last month, when gas wholesale prices reached the record level of 340€/MWh – triggering also sky-high electricity prices – the European textiles industry called on the European Union to adopt a wholesale price cap for gas, the revision of the merit-order principle in the electricity market, support for SMEs and a single European strategy. On 14 September 2022, on the occasion of the State of the Union address by President Von der Leyen, the Commission announced initiatives aimed at tackling the dramatic energy crisis that the Europe is facing.

We, the European associations representing the whole textiles’ ecosystem,  welcome these proposals by the Commission to change the TTF benchmark parameters and decouple the TTF from the electricity market and the revision of the merit-order principle for the electricity market, which is no longer serving the purpose it was designed for.

We also welcome the proposal to amend the state-aid framework that, in our view, should include the textiles finishing, the textiles services and the nonwoven sectors as well as a simplification of the application requirements. Furthermore, we call for a uniform implementation across the EU.

However, we acknowledge that the Commission proposal lacks in ambition and – if confirmed – it will come at the cost of losing European industrial capacity and European jobs. Ultimately, Europe will remain without its integrated textiles ecosystem, as we know it today, and no mean to translate into reality the EU textiles strategy, for more sustainable and circular textiles products.

An ambitious and meaningful European price cap on the wholesale price of natural gas is absolutely necessary. Europe is running out of time to save its own industry. It is now time to act swiftly, decisively in unity and solidarity at European level. We understand a very high price cap has been so far discussed among Ministries and that is not reassuring for companies across Europe: if any cap is, as expected, above 100/MWh, these businesses will collapse.

Already in March 2022, with EU gas wholesale prices at 200€/MWh, the business case for keeping textiles production was no longer there. To date, natural gas wholesale prices have reached the level of 340€/MWh, more than 15 times higher compared to 2021! Currently, many businesses have suspended their production processes to avoid the loss of tens of thousands of euros every day. We hope this will not become the new normal and – to reduce the likelihood of such a scenario – we call on the Commission, the EU Council and the Parliament to swiftly adopt decisive, impactful and concrete actions to tackle the energy crisis and ensure the survival of the European industry.

Given the dire international competition in which the EU textiles industry operates, it is not possible to just pass on the increased costs to consumers. Yet, with these sky-high prices, our companies cannot afford to absorb those costs. The EU textiles companies are mainly SMEs that do not have the financial structure to absorb such a shock.  In contrast with such reality in Europe, the wholesale price of gas in the US and China is 10€/MWh, whereas in Turkey the price is 25€/MWh. If the EU does not act, our international competitors will easily replace us in the market, resulting in the de-industrialisation of Europe and a worsened reliance on foreign imports of essential products.

Specific segments of the textile industry are particularly vulnerable:

• The man-made fibres (MMF) industry for instance is an energy intensive sector and a major consumer of natural gas and electricity in the manufacturing of its fibres. Not only is it being affected by higher energy process, it is also experiencing shortages and sharply rising costs of its raw materials.
• For the nonwovens segment, production processes – which use both fibres and filaments extruded in situ – are also highly dependent on gas and electricity. Polymers melting and extrusion, fibres carding, web-forming, web-bonding and drying are energy-intensive techniques. Nonwoven materials can be found in many applications crucial to citizens like in healthcare (face masks) or automotive (batteries).
• It also is to be noted that for some segments the use of gas has no technological substitute: for example, the dyeing and finishing production units make very intense use of gas. These production units are mainly composed by boilers and driers, which only work on gas and there is no alternative technology.
• The textile services sector is also struggling: with the critical nature of the service they provide, they require a considerable amount of energy to keep services, particularly hospitals and care homes stocked with lifesaving material as well as clothing and bed linens for the patients themselves. Losing these businesses would cause a lack of clothing for healthcare professionals, including protective sanitary gowns for surgeons, nurses and doctors, uniforms including other forms of personal protective equipment.

Shorter product life cycles and rapid technological progress are changing the product landscape at an ever-faster pace. The ability to anticipate future changes and to proactively shape the change is therefore an increasingly decisive competitive factor for modern companies. Trends are considered to be important indicators of impending

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, stands out in the industry not least for its innovative strength, as evidenced by numerous awards such as the Techtextil Innovation Award 2022 in the “New Concept” category. At this year’s Global Fiber Congress Dornbirn, Innovation Manager Ilka Kaczmarek will give an insight into the innovation management of the Bavarian fibre experts in her presentation “Trend Management meets Open Innovation: Best Practice Examples from Kelheim”. Ilka Kaczmarek will show how successful product solutions were developed in a short time by focusing on customer needs and working closely with partners along the value chain.

Natalie Wunder, Project Manager at Kelheim Fibres, will explain one of these examples in detail in her presentation “Development of Menstruation Pants using Speciality Viscose Fibres”. Based on the current trend and the desire of end customers for reusable products, Kelheim Fibres was able to develop a washable and thus reusable, yet bio-based solution for feminine hygiene products.

A new fabric inspection technique for accurately detecting the most subtle of defects on patterned fabrics during high speed production has been developed by BTMA member Shelton Vision, of Leicester, UK.

The patent-pending system has been integrated into the company’s WebSpector platform and validated through factory trials on a purpose-built full scale in-house demonstration system with sophisticated fabric transport capabilities. As a result, a first system has already been ordered by a manufacturer of both plain and patterned fabrics, including camouflage, in Colombia. This follows the successful conclusion of a 21-month Innovate UK project in which techniques for the resolution of complex pattern deformations were developed by machine vision and computer scientists in the company, backed up by the machine vision and robotics department at Loughborough University.

Restrictions
Traditional methods for defect detection rely on human inspection which is ineffective, with detection rates under 65%, while the Shelton WebSpector machine vision system offers a sophisticated platform for automated defect detection of over 97%, but until now has been restricted to plain textiles.

While pattern matching and neural network approaches have previously been tried for patterned textiles, they have failed to provide a practical solution due to the extreme complexity associated with pattern matching on deformable substrates like textiles, as well as the time required to train a neural network for each pattern type.

Challenges
The challenge is that fabrics are not rigid and can be creased or stretched and are also subject to local distortion,” says Shelton Vision Managing Director and CEO Mark Shelton. “As a result, inspection without the technique we have developed, would lead to thousands of false positives. Our sophisticated pattern inspection software techniques ensure a clean image, allowing the detection of faults on fabrics running at speeds of up to a hundred metres a minute.”

The full system consists of:

• A camera and lighting system for optimum image capture at high speed and associated image processing hardware.
• Self-training software utilising statistical analysis to automate the system configuration for new textile products.
• An advanced suite of defect detection algorithms for the detection of all textile defect types.
• An AI-driven defect classification system which learns and automates defect naming in real time, as well as a real time defect grading capability based on client decision rules.
• A system for recording and retrieving complete roll map images for subsequent review and quality control.

The generation of textile roll maps with complete defect data allows for an optimised textile cut plan, improved downstream processing and quality assurance.

• European Textile Industry calls for immediate action to tackle the energy crisis;

The European textile & fashion in Europe, represented by EURATEX, calls for a single European strategy to tackle this energy crisis. To safeguard the future of the industry, a revision of the electricity price mechanism is necessary and an EU wide cap on gas prices at 80€/MWh. Special company support needs to be granted to avoid bankruptcy and relocation of textile production outside Europe.

Gas and electricity prices have reached unprecedented levels in Europe. Due to severe global competition in the market that characterizes the European textile & clothing industry, these cost increases are impossible to pass on to customers. This has already led to capacity reductions and production stops. Closures and the shift of production outside Europe are being forecasted should the current situation persist, leading to further de-industrialization of our continent and increased dependency on external suppliers.

Specific segments of the textile industry are particularly vulnerable. The man-made fibres (MMF), synthetic and cellulose-based fibres, industry for instance is an energy intensive sector and a major consumer of natural gas in the manufacturing of its fibres. The disappearance of European fibre products would have immediate consequences for the textile industry and for society at large. The activities of textile dyeing and finishing are also relatively intensive in energy. These activities are essential in the textile value chain in order to give the textile products and garments added value through colour and special functionalities (e.g. for medical applications).

The European textile industry calls for an EU-wide cap on gas prices at €80/Mwh, and a revision of the price mechanism for the electricity market, to reduce the huge price gaps with our foreign competitors.

Governments should ensure that critical industries, such textiles and all its segments, are able to ensure gas and electricity contracts towards the end of the year at an affordable price. Stable and predictable energy supply is of the utmost importance. Gas restrictions and rationing must only be used as a last resort. No mandatory consumption cuts should be foreseen.

In addition to these measures under discussion, currently a proliferation of contradictory, uncoordinated national initiatives to tackle the energy crisis is observed. This has led to a de facto fragmentation of the Single Market, resulting in a chaotic policy and regulatory environment that adds a further strain on our supply chain, which is fully integrated at European level. Measures that guarantee a level playing field in the EU are utmost important.

EURATEX President Alberto Paccanelli explained: “Given the current situation, a scenario where entire segments of the textiles industry will disappear can no longer be excluded. This would lead to the loss of thousands of companies and tens of thousands of European jobs and would further aggravate the dependency of Europe to foreign sources of essential goods. This applies specifically to SMEs who need temporary support measures (e.g. state aids, tax relieves, energy price cap) to survive the current crisis and to prepare for the green transition in the longer run.”

The world’s largest fashion brands and retailers must increase transparency to tackle the climate crisis and social inequality, according to the latest Fashion Transparency Index.

The seventh edition of the Fashion Transparency Index ranks 250 of the world’s largest fashion brands and retailers based on their public disclosure of human rights and environmental policies, practices, and impacts, across their operations and supply chains.

• Brands achieved an average score of just 24%, with nearly a third of brands scoring less than 10%
• The majority of brands (85%) do not disclose their annual production volumes despite mounting evidence of clothing waste around the world
• Most major brands and retailers (96%) do not publish the number of workers in their supply chain paid a living wage

The Index reveals insights into the most pressing issues facing the fashion industry, like:

• As new and proposed legislation focuses on greenwashing claims, almost half of major brands (45%) publish targets on sustainable materials yet only 37% provide information on what constitutes a sustainable material.
• Only 24% of major brands disclose how they minimise the impacts of microfibres despite textiles being the largest source of microplastics in the ocean.
• The vast majority of major brands and retailers (94%) do not disclose the number of workers in their supply chains who are paying recruitment fees. This paints an unclear picture of the risks of forced labour as workers may be getting into crippling debt to accept jobs paying poverty wages.
• While many brands use their channels to talk about social justice, they need to go beyond lip service. Just 8% of brands publish their actions on racial and ethnic equality in their supply chains.

Despite these results, Fashion Revolution is encouraged by increasing supply chain transparency among many major brands, primarily with first-tier manufacturers where the final stage of production occurs, e.g. cutting, sewing, finishing and packing. Nine brands have disclosed their first-tier manufacturers for the first time this year. It is encouraging to see significant progress across market segments including luxury, sportswear, footwear and accessories and across different geographies.

Fashion Revolution’s co-founder and Global Operations Director Carry Somers says: “In 2016, only 5 out of 40 major brands (12.5%) disclosed their suppliers. Seven years later, 121 out of 250 major brands (48%) disclose their suppliers. This clearly demonstrates how the Index incentivises transparency but it also shows that brands really are listening to the millions of people around the world who keep asking them #WhoMadeMyClothes? Our power is in our persistence.”

More key findings from the Fashion Transparency Index 2022:

Progress on transparency in the global fashion industry is still too slow among 250 of the world’s largest fashion brands and retailers, with brands achieving an overall average score of just 24%, up 1% from last year
For another year, the initiative has seen major brands and retailers publicly disclose the most information about their policies, commitments and processes on human rights and environmental topics and significantly less about the results, outcomes and impacts of their efforts.

Most (85%) major brands still do not disclose their annual production volumes despite mounting evidence of overproduction and clothing waste
Thousands of tonnes of clothing waste are found globally. However, brands have disclosed more information about the circular solutions they are developing (28%) than on the actual volumes of pre- (10%) and post-production waste they produce (8%). Brands have sat by as waste importing countries foot the bill, resulting in serious human rights and environmental implications.

Just 11% of brands publish a responsible purchasing code of conduct indicating that most are still reluctant to disclose how their purchasing practices could be affecting suppliers and workers
Greater transparency on how brands interact with their suppliers ought to be a first step towards eliminating harmful practices and promoting fair purchasing practices. The poor performance on transparency in this vital area is a missed opportunity for brands to demonstrate they are serious about addressing the root causes of harmful working conditions, including the instances where they themselves are the key driver.

Despite the urgency of the climate crisis, less than a third of major brands disclose a decarbonisation target covering their entire supply chain which is verified by the Science-Based Targets Initiative
Many brands and retailers rely heavily on garment producing countries that are vulnerable to the impacts of the climate crisis, yet our research shows that only 29% of major brands and retailers publish a decarbonisation target covering their operations and supply chain which is verified by the Science Based Targets Initiative.

Only 11% of brands publish their supplier wastewater test results, despite the textile industry being a leading contributor to water pollution
The fashion industry is a major contributor to water pollution and one of the most water intensive industries on the planet. Only 11% of major brands publish their wastewater test result, and only 25% of brands disclose the process of conducting water-related risk assessments in their supply chain. Transparency on wastewater test results is key to ensuring that brands are held accountable for their potentially devastating impacts on local biodiversity, garment workers and their communities.

Most major brands and retailers (96%) do not publish the number of workers in their supply chain paid a living wage nor do they disclose if they isolate labour costs
Insufficient progress is being made by most brands towards ensuring that the workers in their supply chain are paid enough to cover their basic needs and put aside some discretionary income. Just 27% of brands disclose their approach to achieving living wages for supply chain workers and 96% do not publish the number of workers in their supply chain paid a living wage. In response, we have joined forces with allies across civil society to launch Good Clothes, Fair Pay. The campaign demands groundbreaking living wage legislation across the garment, textile and footwear sector.

• Rising global demand for particularly high-performance silicon carbide (SiC)-based semiconductors

• Increase in production capacities at the Shanghai (China), St. Marys (USA) and Meitingen (Germany) sites

SGL Carbon will significantly increase capacities for the production of graphite products for the semiconductor industry by 2024. As part of the investment budget for the Business Unit Graphite Solutions set out in the medium-term planning, a mid-range double-digit million euro amount will be made available for the expansion of production over the next two years. The company is thus responding to the strong growth in demand in this sector and strengthening its commitment to the global megatrend of digitalization.

The expansion program will take place in several steps over the next two years. In St. Marys, North America, and at the Chinese site in Shanghai, capacities for purification and for high-precision, computer-controlled processing of graphite components and felts will be expanded. In Meitingen (Germany), a new plant for the production of carbonized and graphitized soft felt is under construction. Further capacity expansions at various locations are being planned.

According to the World Health Organization (WHO), cardiovascular disease is one of the most common natural causes of death. Every year, it is the cause of death of around 17 million people worldwide. The Peter Dornier Foundation Prize 2022 has now awarded a research work that is to improve the medical care of people with insufficient heart valve function in the future and prolong the patients' lives.

The human heart is a high-performance machine: over the course of a person's life, it beats almost three billion times, pumping around 200 million litres of blood through the body. Enormous stresses that can sometimes lead to life-threatening signs of wear and tear. If a heart valve gets out of step, patients usually get artificial-mechanical or biological valves as a replacement. However, mechanical solutions imply patients to take blood-thinning medication for the rest of their lives. In addition, there may be audible closing noises. For example, almost a quarter of patients with mechanical heart valves complain of sleep disturbances. Biological heart valves, on the other hand, such as those made from animal tissue, require a great deal of manual work and have a shorter lifetime.

Potential of weaving for medical products demonstrated
For this reason, Graduate Engineer Mathis Bruns at the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at the TU Dresden is researching an implant alternative made of fabric. As part of a research project that also involved heart surgeons from the Dresden Heart Centre and the University Hospital in Würzburg, Mr. Bruns provided important findings for weaving an artificial heart valve in his diploma thesis. For his work entitled "Development of tubular structures with integrated valve function", Mathis Bruns has now received the Peter Dornier Foundation Prize 2022, endowed with 5,000 euros. In his laudation, Dr. Adnan Wahhoud, former head of the development department of air-jet weaving machines at DORNIER in Lindau, said: "With his work, the winner of the award demonstrates very clearly the potential of weaving technology to produce fabrics of complex form, geometry and structure with the aim of prolonging and improving people's lives." The award-winning thesis enriches research into three-dimensional tissues for use in medicine.

Weaving replacement heart valves without seams
"A particular advantage of our approach is the integral production method", says foundation prize winner Mathis Bruns. “The geometry and function of a heart valve is that complex that woven heart valves could not be produced in this form previously. Through the combined use of a rigid rapier weaving machine with bobbin shield and a Jacquard machine, it is possible to weave the replacement heart valve in such a way that it no longer has be sewn together. Even the tubular structures for the blood vessels and the integrated valve function are ‘all of one piece’. Seams are always a weak point in textile medical products," Mr. Bruns adds. “Another advantage of the woven heart valve is the possibility to insert it by the help of minimally invasive surgery. Hence, the folded valve which is about the size of a tea light is to be pushed with a catheter via the bloodstream to the target position in the heart and unfolded there. The patient's chest and heart would then no longer have to be cut open”, explains prize winner Mr. Bruns.

Textile structure is similar to human tissue
A wide variety of medical products have always been produced on DORNIER weaving machines. Customers use them to produce fabrics for bandages, prostheses, blood filters and orthoses among other things. For Mathis Bruns, it is only evident that implants such as heart valves will more and more be woven on the machines from Lindau in the future. "Textile tissue is very similar to human tissue," he says. The human body consists largely of thread-like materials, just as a textile fabric is made up of thousands of individual threads. "Muscle fibres convey force impulses, nerve tracts send stimuli such as pain and brain cells convey information via thread-like dendrites and axons." Because of their ‘thread-like properties’, woven implants are therefore particularly suitable for medical applications.
