Context
Microorganisms are devastating for textile materials, when their number is not kept under control or in the event of a poor maintenance of e.g. bedding items (sheets, mattrass pads...).
Microorganisms in textiles cause several problems including deterioration of the fabric, aspect changes (spots, colour change and decoloration), odours, and may even induce health problems, such as allergies.
