Abstract
Abstract A cast lining fabric is prepared from hydrophilic synthetic material. The cast lining transports moisture from the skin and environment beneath a cast to the outside environment where the moisture is removed by evaporation providing a dry atmosphere beneath the cast. The resulting dry environment reduces the ill effects of bacterial, fungal and mildew growth, reduces odor, increases dryness and comfort, and allows the wearer to bathe and swim.
