Apparel as a resource – results of a literature review and laboratory textile tests of garments subjected to the laundry

Heller, Claudia; Fuchs, Monika; Thamsen, Paul U.

The objective of the study was to obtain an overview of existing literature on the ageing of apparel on the one hand and to carry out its own series of tests on the other. Almost 30 relevant scientific studies were evaluated. All the authors approached their studies differently and were able to gain many insights into the effects of the laundry care process, but no study explicitly deals with household circumstances. Therefore, the present study highlights this part. Two trousers are washed in the gentle washing program and dried in the air. Evaluations of the laundry load were conducted prior to washing, as well as after various wash and dry cycles. The test methods air permeability, colour range, dimensional stability (thickness and measurements of the trousers), subjective hand-feel and total mass were used. The main differences between the trousers in the tests are the substrates and the textile manufacturing methods. This is reflected in the results of the test methods. Trousers with a higher cotton content are more susceptible to the washing process parameters, i.e. the time, temperature, mechanics and chemistry. Overall, the study documents a status quo on the behavior of an average garment in the care phase of 20 washing cycles.
