In order to achieve the SDG 12, which aims to ensure sustainable consumption and production patterns, the fashion industry needs to shift. This industry accounts for 10% of the total global carbon emissions and if no change is made, this number will be 26% by 2050. Particularly on the outdoor fashion industry, many initiatives have already been taken to reduce the ecological footprint such as increasing the durability of products. For a product to be durable, its functionality must prevail over time. This study investigates the functionality of membrane laminate fabrics exposed to artificial weathering, focusing on their performance in terms of water repellency, air permeability, breathability, and water penetration resistance. The method involves evaluating the original and the aged fabrics to measure changes in their functional properties, following ISO standards, contributing to understand the durability of the fabrics. Results demonstrate that ePTFE membrane is the least affected by weathering whereas PET and PU have a bigger decrease in functionality after the aging process. The study highlights the importance of developing more durable and PFC-free membrane laminate fabrics that can provide the same level of functionality as membranes that need PFCs in its production such is the case of ePTFE. The outcome of this research have implications for fabric manufacturers and sustainability-focused consumers specially outdoor enthusiasts, providing insight into sustainable production and consumption. The analysis also identifies possible future studies that ought to be done including an environmental assessment concerning durability of the material and hazardous substances presence.
