Sustainable clothing is manufactured using natural fabrics such as organic cotton, hemp fibre or unbleached wool. Besides being good for the environment, they are also good for your skin. Also materials like recycled polyester, which allow to give a new life to the tons of plastic that are discarded every year, are used in eco-sustainable fashion. In Spain, one of the pioneering brands in using recycled materials in Spain was Ecoalf.
Another key aspect in the manufacture of clothes is dyeing. The dyeing process is one of the most polluting in textile production, as it consumes large amounts of water and mostly uses chemicals that are toxic to both health and the environment. Unsustainable industrial dyeing processes consume around 150 litres of water to process 1 kg of fabric. In addition, their wastewater is highly polluting.
For a clothing brand to be considered sustainable, it must use low-aggressive and biodegradable pigments. But it's not just a question of what dyes it uses, but also the processes it uses to give its garments their colour. Dyeing the raw fabric roll has a much lower ecological impact because it consumes less water, while dyeing the garments one by one, although it is cheaper at the production level, has a very high cost for the planet.
