| Processing - description | Traditional bleaching: After obtaining the fibre (through retting, soaking, and mechanical processing), nettle was often naturally bleached by exposure to sunlight and repeated washing in clean water. This process could take several weeks to months, during which the fibres gradually became lighter. Alkaline bleaching: Modern experiments as well as traditional methods use soaking in a strong alkaline solution (e.g. wood ash lye or sodium hydroxide) to remove remaining pectin, waxes, and green plant residues from the stem. After alkalisation, the fibres are thoroughly rinsed and often neutralised in vinegar water, resulting in a lighter or even white shade. Mechanical cleaning: After bleaching, the fibres are further combed and brushed to remove any remaining impurities and to achieve maximum fineness and whiteness. |
