Milk fibre is made from leftover milk that can no longer be used for food production and would usually be discarded. Instead of disposing of it, companies such as QMilk turn the milk into a protein fibre which is suitable for the textile industry. Milk fibre has a soft and smooth feel and is beneficial for the skin, therefore making it an ideal choice for people with allergies or skin sensitivity. The fibre itself is biodegradable, and clothing made from milk fibre has antibacterial properties and absorbs moisture well.
