Description

Textiles made of synthetic fibres can lose microparticles during household washing, which can then enter rivers, lakes and oceans. The goal of Textile- Mission is to reduce the related environmental impact. The project is pursuing an interdisciplinary approach with partners from the Sport Goods Industry, research, the detergent and household aplliance sectors, and environmental protection. On the one hand, sport and outdoor textiles with significantly lower microplastic emissions than at present will be developed through textile technology research and the optimisation of production processes. Textile researchers and the sportswear manufacturers involved are also testing biodegradable fibres as an environmentally friendly alternative. With the support of the WWF, care is taken to ensure that other aspects of sustainability are considered. On the other hand, a contribution will be made to optimise wastewater treatment plant technology. Practical innovations at this level could also help to reduce microplastic inputs from non-textile sources. In parallel, data on the extent and range of microparticle emissions from different textiles are systematically collected through tests of washing and laboratory wastewater treatment plants to improve the understanding of the respective material flows.

Main areas of work

  • Status quo analysis: the microplastic output of marketable textiles
  • Wastewater treatment plant technology: the retention capacity of different cleaning or purification steps
  • Holistic perspective: sustainability aspects of alternative materials
  • Textile research: biodegradable materials and new cutting and processing possibilities
  • Product development: production and testing of prototypes

Short description
The Federal Association of the German Sport Goods Industry e.V. (BSI) will coordinate the project and is responsible for public relations in consultation with the WWF. In addition to maintaining the website and sending out press releases, this also includes organising multi-stakeholder events. The BSI will conduct a study on the spread of microparticles and the polyester-based microparticle emissions associated with household laundry and collect data on the annual emissions of textile polyester microparticles. Moreover, recommendations will be given on how new materials, manufacturing processes, optimised wastewater treatment plant technology, etc. can help to sustainably reduce microparticle emissions.

WP 2 Development of textile structures for sports and outdoor applications with reduced particle emission in textile washing and based on biodegradable polymers

Short description
Starting with a status quo analysis, the risk of microparticle emissions from textiles during household laundry will be determined in cooperation with the Technical University of Dresden and the BSI. For this purpose, standard articles from German households, problem articles made of fleece and ”top sellers” from the industrial partners involved are washed to quantify the microparticles released. Another focus lies on the development of alternative materials, cutting and processing possibilities. For this purpose, low-emission construction, processing and finishing methods are researched and materials made of or in combination with biopolymers are produced. Finally, as a recommendation for the textile industry, a method for predicting the emission risk of newly developed textile articles will be presented.

WP 3 Microplastics of textile origin – A holistic approach: optimised processes and materials, material flows and environmental behaviour.

Hilke Anna Patzwall, VAUDE Sport GmbH & CO. KG, VAUDE Straße 2, 88069 Tettnang, e-mail: hilke.patzwall@vaude.com

Short description
The outdoor clothing specialist VAUDE will provide materials and finished products for status quo analysis and assist in the selection of other test materials and products. Niederrhein University of Applied Sciences will develop new materials and construction methods to be tested in coordination with the partners. After passing the performance test, the materials will then be assembled into prototypes. The knowledge gained during the manufacturing process will in turn be reflected into the research network - here the question is about i.a. the processability of the materials using conventional sewing machines, among other things.

WP 4 Polyester fibres: Reduction of microparticle release and material flow analysis in the environment

Contact person
Prof. Dr. Stefan Stolte, Technical University of Dresden, Institute of Water Chemistry, Chair of Hydrochemistry and Water Technology, 01062 Dresden, e-mail: stefan.stolte@tu-dresden.de

Short description
At the TU Dresden, an analysis and sample preparation method is established that makes it possible to quantify microparticles from wastewater streams and fractionate them according to size. In addition, the researchers will investigate the retention capacity of textile (fluorescence-labelled) microparticles in the different stages of a laboratory wastewater treatment plant and identify efficient retention possibilities. Material flows are analysed including a first estimate of the Germany-wide textile microplastic emission from wastewater into water bodies /soils is made. In addition, biopolymer-based microplastics (obtained from washing tests with alternative materials at the Niederrhein University of Applied Sciences) will be tested according to their environmental stability to derive design proposals.

WP 5 Consideration of other environmental issues related to the project, stakeholder involvement and communication at the end of the project

Contact person
Dr. Bernhard Bauske, WWF Germany, Kaiserstraße 70, 60329 Frankfurt e-mail: bernhard.bauske@wwf.de

Short description
Throughout the course of this project, WWF Germany will ensure that sustainability aspects are taken into account even though they are not directly linked to the topic of microplastics. WWF will conduct a study about possible areas of tension that may arise with alternative fibres made of bio-based plastics and wood. For example, the cultivation of textile raw materials vs. cultivation of foodstuffs. Another study will focus on the retention of textile microfibre particles through various purification stages in wastewater treatment plants. At the same time, the WWF wants to involve important stakeholders from NGOs, consumer associations and academia in the project.

Associated partners and their contributions

adidas AG will provide materials and finished products for status quo analysis and assist in the selection of additional test materials and products. The sporting goods manufacturer will examine the newly developed materials at the Niederrhein University of Applied Sciences, University of Applied Sciences for general marketability and participate in the production and testing of prototypes. The company will also support the BSI in its press and public relations work.

Henkel AG & Co. KGaA will advise the Niederrhein University of Applied Sciences on the construction of the test bench. The company will also support household laundry and wearing test by contributing its expertise on typical household washing and drying parameters.

Miele & Cie KG will provide the Niederrhein University of Applied Sciences with four household washing machines for the course of the project. In cooperation with Henkel AG & Co. KGaA, the washing machine manufacturer will accompany the household laundry tests and support the modification of the washing processes with its expertise.

Polartec LLC: The world‘s largest fleece manufacturer Polartec LLC will support the project with its expertise in the production of fleece and provide standard products for comparisons. In addition, materials developed by the Niederrhein University of Applied Sciences will be prototyped and tested for scalability at the Polartec production sites.
