DIN SPEC 4872 is a standardized test method for determining and classifying the environmental impact of textiles during washing. The test method examines how many fibers are discharged when textiles are washed, how well these fibers degrade in wastewater and how harmful the fiber residues are to the environment.
Once the test has been completed, we assign a classification code, which reflects the degree of fiber discharge, the biodegradation rate and the ecotoxicological potential of the textile product.
The Hohenstein Quality Label - Tested Environmental Impact - transparently communicates the environmental impact during washing.
Using analytical methods, we quantify:
The DIN SPEC 19292 test procedure uses tabletop equipment and a defined amount of water to simulate a washing process on a fabric sample. The sample water is filtered, and the degree of fiber fragmentation is determined by visual evaluation with a microscope.
The method is designed to be as accurate and accessible as possible. It can be used by product developers throughout the supply chain.
In considering the environmental impact of textiles, there’s no way around microplastics. Hohenstein has been at the forefront of this research since 2016.
Along with the University of Leeds and other textile industry leaders, Hohenstein is a contributing research member of the Microfibre Consortium (TMC). We're working to minimize microplastic emissions from textiles and increase sustainability in textiles.
This test kit is designed to help textile companies develop/choose lower shedding materials.
