Technological progress often occurs by accident. Once overlooked resources can become instrumental parts of a new way forward for an entirely different industry. Used coffee grounds have a lot of interesting chemical properties that so far have not been put to use. Analysis of these properties has led to innovation and vast improvements in performance.
But this unlikely ingredient is just one that’s helping us clean up fashion - currently one of the most polluting and unsustainable industries on the planet - while also creating garments that perform better than traditional fabrics. The farming of cotton alone accounts for 24% of global insecticide sales and its production also demands massive amounts of fresh water (a staggering 6,000-10,000 litres per kilo of cotton). This is why innovative textiles are so important.
Enter S.Cafe® - a fabric made from recycled polyester fibres infused with roasted coffee grounds, which give it superior odour-control properties. One gram of the coffee grounds, which would otherwise go to landfill, can have a surface area of several square metres. The naturally present caffeine is rich in nitrogen compounds, which act as a magnet to airborne odour particles and are also known to suppress the metabolism of bacteria and viruses. These two surface chemical effects combine to help S.Cafe® capture body odours about three times more efficiently than other fabrics.
The benefits go on. The surface of coffee particles is also highly non-uniform and reflective, enhancing UV ray blocking. And all that microporosity gives S.Cafe® garments superior hygroscopic (water absorbing) properties compared to cotton or polyester fibres, drying 200% faster than their cotton counterparts - making them incredibly effective at wicking moisture away from the surface of the skin.
Better performance, lower output. Train hard, tread soft.
