From the Sector

The substance graphene can become increasingly important as a component in textile catalysts when purifying water from textile dyeing as has been shown in a recently completed doctoral project at the University of Borås.

In his project, Milad Asadi, a new doctor in Textile Technology, has modified conventional yarn by encapsulating iron particles in graphene and developed a multifunctional smart e-textile. The focus was on developing a method for purifying wastewater from textile dyeing. The smart e-textile acts as a catalyst that causes the substance hydrogen peroxide to be formed, which is needed in order to break down pollutants in wastewater.

The project has generated a complete textile reactor for the treatment of wastewater through the so-called electro-Fenton technology, which is mainly used industrially to purify wastewater. The novelty of the technology is to use the properties of both graphene and iron, which is the main catalyst.

“Previous research has mainly been about the treatment of wastewater by using chemicals to break down the textile dyes. My project is the first where graphene, which is electrically conductive, is used to encapsulate iron. The e-textile can also be used several times, unlike when chemicals are used and which are then rinsed off. The challenge in the project was to scale up the technology so that the treated yarn can be fed into automatic knitting machines”, explained Milad Asadi.

The e-textile catalyst can be reused and hydrogen peroxide is formed internally inside the reactor, which reduces the use of biological catalysts, making the technology more sustainable compared to chemical methods.

ANDRITZ will be presenting its innovative solutions for nonwovens production and textile manufacturing at INLEGMASH 2022 in Moscow, Russia, from March 14 to 17.

AIRLAY TECHNOLOGY
Protecting the environment and conserving natural resources require new technologies. In the textile-related industries, the current challenge is to develop industrially and economically viable solutions to use eco-friendly fibers in nonwovens. ANDRITZ focuses on the airlay nonwoven application for hemp fibers (used in mattress production, insulation, ...) and also geotextile end uses.

TEXTILE RECYCLING TECHNOLOGIES
ANDRITZ Laroche is a leading supplier of fiber processing technologies such as opening, blending, and dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses. ANDRITZ will present recycling technologies for end-of-life textile products that can be used in multiple applications, such as automotive, insulation, mattresses, and furniture felts.

Customer awareness and regulations are pushing apparel brands to recycle their textile waste and use the recycled textile fibers in their own products. To support ANDRITZ customers, a team with process know-how is available to conduct customized trials in our advanced technical center located at the ANDRITZ Laroche facilities in Cours, France.

BAST FIBERS
For the demanding Russian market for technologies based on bast fibers, ANDRITZ will present innovative products and the valorization of bast fibers, in particular hemp.
ANDRITZ Laroche is a player in the textile waste recycling sector, with airlay nonwoven technologies but also bast fiber decortication and cottonizing lines.

These eco-friendly fibers are used to spin yarn mixed with cotton, saving cotton as raw material, which reduces the consumption of water, pesticides applied in its cultivation and chemicals used during the dyeing and finishing processes.

Following the European Commission’s update of the 2020 New Industrial Strategy: ‘’Building a stronger Single Market for Europe’s Recovery’’, the European Social Partners for the Textile, Clothing, Leather, and Footwear (TCLF) sectors came together to call for support via a dedicated strategy.  The Strategy aims to help guide the TCLF industries through the current green and digital transition, while facing tough global competition, stressing the need to safeguard the industries and protect jobs in Europe.

On 25 May, employers’ and workers’ representatives for the European TCLF sectors met with the European Commission to discuss the current challenges facing the TCLF industries and potential EU action to help support the sectors and their workers.  Following discussions on the terrible impact of COVID-19 on the sectors and the need for a strong EU action, the Joint Statement: ‘’The future industrial strategy of the EU Textiles Ecosystem (TCLF sectors)’’ was adopted.

The Joint Statement highlights the need for a dedicated strategy with support at national and EU level to help the TCLF sectors survive following the COVID-19 pandemic, while they continue to face tough, and, sometimes unfair, global competition. The Social Partners of the TCLF industries fully support the EU’s ambitions for a green and digital transition of the sectors, but insist on concrete European measures to help the industries transform while the continues to suffer from an unlevel global playing field.

Specific joint demands include: full engagement with Social Partners in both the recovery and the transition of the industries, support for the EU Pact for Skills for the relevant ecosystem, a revision of the GSP which doesn’t negatively impact the sectors and its workers, support to decarbonise the sectors, careful consideration of the Due Diligence Legislation and quality dialogue with Social Partners ahead of the EU Sustainable Products Initiative and the Consumer Agenda to ensure that all policy gaps are addressed. Special attention must also be given to the forthcoming EU Textiles Strategy which should fully represent the needs of the EU’s entire textiles ecosystem.
