Sustainability/house-sustainabilityThe new Freudenberg fusible interlinings for shirts and blouses have been developed in such a way that they are harmless to people and the environment at the end of their life cycle. With this innovation, the world’s leading specialist in woven, knitted, weft, and nonwoven interlinings further reduces the impact on the environment.
Approved by Hohenstein LaboratoriesGermany’s independent Hohenstein Laboratories performed biodegradation tests on the 46xx series, based on the Hohenstein method which draws on DIN EN ISO 11721-2:2003 and EN ISO 846, and approved it as biodegradable and eco-toxicologically harmless. The tests by Hohenstein showed no negative effects on either the germination of garden cress or on earthworms in the acute toxicity test.
The new biodegradable shirt interlinings also show significant potential for energy savings, as the fusing can be performed at a low temperature. Concretely, this means that the resulting temperature between the upper fabric and the shirt interlining during fusing is only 127°C which is significantly lower than the commonly used temperature of 143°C.
Certified to OEKO-TEX® STANDARD 100 Class II for successfully testing for no harmful substances, the shirt interlinings are washable at up to 40°C and resistant to dry cleaning. Freudenberg further proved in washing and degradability tests that the interlining is superior to conventional products in terms of quality. In addition, it has also passed all ecological-toxicological tests and is a perfect end-of-life cycle solution.
