The fibres we use to produce our textiles have considerable beneficial effects - suffice to think of bamboo charcoal, known to release anions that activate our surface cells, purifying the blood, reducing tiredness and improving our health (underwear ). The milk protein, casein, used to make yam, nourishes and softens the skin, it is anti-bacterial and healthy and can be used instead ofwool for certain articles. Soya, for fabrics with excellent breathability and the capacity to trap heat, is resistant to bacteria, comfortable and known as plant cashmere.
