Damaged Analysis of Silk
Reports on faults with silk fabrics are more common than would be expected from their share of the world fibre market (about 0.1%). One reason for this is that silk is particularly delicate. Mechanical treatment, especially in the wet state (dyeing and finishing as well as household laundering), causes irreparably abraded areas, the so-called blanched places. Defibrillation and splitting off of the silk filaments causes incident light to be scattered diffusely.
