From the Sector

From April 2023, OEKO-TEX® will officially launch its new ORGANIC COTTON label. Two initial pilot customers have already been certified by the testing service provider Hohenstein: the Indian textile supplier Milan Group and the Turkish cotton producer Akasya.

The new organic label ensures that all requirements for labeling as organic cotton are met. In addition to testing in accordance with OEKO-TEX® STANDARD 100, it ensures that the cotton contains less than ten percent genetically modified material, complies with pesticide limits and guarantees its organic origin.

Textile companies whose products have been certified with the OEKO-TEX® STANDARD 100 can now have their certificates extended to an ORGANIC COTTON certificate after ensuring ecological production.

"A combination with OEKO-TEX® MADE IN GREEN is ideal," explains Ivonne Schramm, Head of OEKO-TEX® at Hohenstein. "This ensures environmental friendliness, transparency and socially responsible conditions in a single certification."

The certificate can be used for ready-made articles (e.g. T-shirt, bedspread, etc.) as well as for textile intermediate products (e.g. intermediate products such as raw fibers, yarns, etc.). Mixtures of organic and conventional cultivation are not permitted.

Within its TEXTILE SOLUTIONS, the CHT Group has developed solution approaches for manufacturing companies in the textile value chain that have to use a lot of energy for their production. This is intended to compensate high energy costs and make a positive contribution to climate protection.Application specialists work with customers to develop individual savings potentials that are specifically tailored to the production facilities and requirements. Thus, depending on the process, fabric and machine, energy savings of up to 30% can be achieved with the use of innovative CHT textile auxiliaries, dyes/pigments and the corresponding process optimisations. In addition, the numerous concepts and optimally matched products can minimise water consumption or shorten the process time.

Energy-efficient cold bleaching instead of pad-steam bleaching processes in continuous pretreatment and the 4SUCCESS process for energy-efficient and resource-saving pretreatment and dyeing of cotton help to save energy. Likewise, the use of polymer binders, which do not require energy-intensive fixation, saves energy.

Efficient pretreatment with the new polymer technology CPT (Comb Polymer Technology) achieves good cleaning effects even with low liquor ratios and thus less water to heat up. To save costs for energy-consuming heating, there is also the gentle low-temperature fixation in the easy care finishing. The OrganIQ EMS Jeans system enables jeans finishing with a reduced application temperature compared to standard processes.

With TIME BOOST, a process for fast polyester dyeing processes, not only significant energy but also time savings are achieved by omitting pre-washing and by shortening heating and migration times. SHORT CUT also leads to shorter process times when dyeing polyamide.

To avoid cost-intensive intermediate drying, the CHT Group offers the SCREEN-2-SCREEN with PRINTPERFEKT S2S which facilitates printing in a wet-on-wet technology.

In addition to numerous other products, the CHT Group also offers its customers digital tools to optimally support process optimizations. The "BEZAKTIV Soaping Advisor" calculation program within the CHT Textile Dyes app can be used to evaluate and improve dyeing and soaping processes in a simple and target-oriented way.

Over the past three years, a dedicated AI development team at BTMA member Shelton Vision has been developing tailored machine learning solutions for the textiles industry.

The aim has been to elevate the detection process and the accuracy of naming and grading subtle defects in textiles, in real time within production environments.

“Big Data ‘off-the-shelf’ systems such as those behind technolgies like facial recognition and Google Maps involve reading many thousands of single images each second and simply take too long to accumulate sufficient data for what’s required in this specific case,” says Shelton Vision CEO and Managing Director Mark Shelton. “A feature of the textile industry is that in many sectors, the product range changes several times within a year and it is not uncommon to have to inspect hundreds, if not thousands of different styles in a year based on precise settings.”

In terms of defect types, he adds, there may typically be over 100 that need to be accurately detected, classified (named) and graded in real time.

“Added to this is the need to ‘filter out’ the random occurrence of ‘non defects’, such as loose threads, lint and dust on the surface – the number of which can be higher than actual defects – and it is clear that a bespoke system is required.”
The development team has consequently established metadata for identifying defect properties, enabling the successful identification of faults from a much smaller number of images.

“The system employs a unique combination of machine learning for automated style training and novel algorithms for defect detection, to provide high quality images for the AI real time defect classification and grading software,” Shelton explains. “Due to the inherent variation in fabric features – raw materials, construction, texture, colour and finishes, as well as the differing product quality standards in value chains and the regional variations in what defects are called – our AI engine uses models built for each individual company or group of companies, or product value chain.”

The AI models are constructed so that the user operatives can populate them with their own data produced by the vision system or by obtaining defect images from another imaging source (eg a mobile phone camera).  

The occurrence of defects is sporadic and many defect types occur infrequently, although when they do, they can have severe consequences. These scenarios re-enforce the need for the AI engine to be quickly set up and able to operate accurately with limited data sets of typically between 30 and 50 good quality images per defect type.

A further feature is a tool enabling the user to periodically ‘clean up’ the AI data during the set up phase. This is used to resolve conflicting data and to correct mis-named images.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

“There is a need for the real time detection of defects that are being created in separate processes, such as printing or coating and for real time automated systems that can accurately determine the defects and their severity and provide a reliable signal for an operative to rectify the issue, This can result in considerable savings.

Prior to Shelton introducing powerful customised machine vision and real time defect classification, the only systems available were those that required manual sifting through vast numbers of images, which included both real defects and ‘non defect’ images. The task was very often overwhelming and did not provide much benefit beyond manual fabric inspection.

January, 3rd, ZDHC announced the release of the updated ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines Version 2.0, and its supporting document. By publishing these documents the industry shall be pushed forward increasingly innovative and sustainable fibre production.

The ZDHC MMCF Guidelines V2.0 now include the Responsible Fibre Production Guidelines, Wastewater Guidelines and Air Emissions Guidelines as three separate chapters in a single document.

Fibres are key components of production processes in the textile and fashion value chain and it is crucial to reduce the environmental impact of their manufacture. ZDHC guidelines give suppliers producing MMCF unified criteria for measuring output indicators like wastewater, sludge, air emissions and other process-related parameters.

Among other changes, this update reflects the expansion of the scope to accommodate Viscose Filament Yarn, Lyocell, Cuprammonium Rayon (Cupro) and Cellulose Acetate (Acetate). The ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0 provide an aligned approach for included fibres, including defined chemical recovery, wastewater and sludge discharge, and air emission discharge.

ZDHC continues to advocate for the improvement of processes which minimise emissions while also working towards the recovery of input substances and by-products. These dual goals, reduction and recovery, directly address the negative impact of outputs arising from MMCF production.

ZDHC MMCF Guidelines Industry Standard Implementation Approach Version 2.0: Additional Industry Support for Implementation
Along with the ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0, ZDHC has also updated its ZDHC MMCF Guidelines Industry Standard Implementation Approach. This document aims to support the implementation process of the ZDHC MMCF Guidelines V2.0, and features new implementation timelines that assist suppliers in setting their goals to achieve Foundational, Progressive or Aspirational Level on the ZDHC Supplier Platform.

Over the past year, TMAS, the Swedish Textile Machinery Association, has been working with ClimatePartner on a corporate carbon footprint (CCF) mapping project with its member companies, as a natural step towards supporting a more sustainable textile industry.

Over half of the members of TMAS are participating in the project, which involves calculating each operation’s Scope 1, 2 and 3 emissions in order to identify the current climate impact and areas where reductions can be made.

“Integrating climate action into strategies is becoming increasingly important in Europe and we have decided to take a pro-active role,” says TMAS secretary general Therese Premler-Andersson. “There is growing pressure from customers to be more transparant in this area and forthcoming legislation will soon make it necessary for all to take climate actions. TMAS members, however, recognise the benefit of taking action now, not least in terms of taking responsibility and demonstrating credibility.”

The CCF project’s scope examines all aspects of a business split into five areas:

• Facility Management (heating, electricity, water, cooling agents and waste disposal).
• Employee Mobility (commuting and company cars).
• Business Travel (flights travel by train, rental cars).
• Procurement (production, packaging and office materials).
• Logistics (inbound and outbound).

Primary data is being used wherever possible and emission factors originate from internationally recognised databases such as ecoinvent and GEMIS.

The ClimatePartner measurement programme is based on the guidelines of the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard (GHG Protocol), and factors in all greenhouse gases covered by the Kyoto Protocol. These are carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulphur hexafluoride (SF₆) and nitrogen trifluoride (NF₃).

Each of these gases affect the atmosphere differently and remain in the atmosphere for different lengths of time. Rather than reporting on each gas separately, they are expressed as a CO₂ equivalent (CO₂e) for the sake of simplicity. A CO₂e is essentially a conversion into a ‘global warming potential’ value that enables the influence of different gases on global warming to be compared.
