Abstract [en]
Global textile production and consumption have increased steadily over the past 15 years, leading to significant impacts on the climate and the environment. In 2022, the EU launched a strategy for sustainable and circular textiles, highlighting that extending the life of textile products is the most efficient way to reduce their climate and environmental impact. Shell jackets for outdoor use are textile products often discarded by their first users and resold on the second-hand market.
This thesis evaluates the perceived, assessed, and measured functionality of second-hand and end-of-life shell jackets. The perceived functionality data were collected through a survey, while the assessed functionality data were obtained using a visual inspection protocol. The measured functionality data were obtained through material testing of the key properties of the jackets’ membrane laminate.
By comparing the results with the jackets’ original performance, the thesis describes how the jackets’ functionality changes over time. The findings indicate that air permeability does not change significantly, while water repellency, water penetration resistance, and breathability decrease over time, although at different rates. The thesis also compares the jackets’ perceived, assessed, and measured functionality and price over time. The results reveal that price decreases more rapidly over time than assessed and measured functionality, but less rapidly than perceived functionality.
The findings of this thesis can contribute to efforts to enhance both the technical and emotional durability of shell jackets and other technical textile products, as well as to improve the evaluation of these products in the second-hand market.
