ABSTRACT:
Dry laid board comprising peat moss is provided and made by harvesting peat moss having a degree of decomposition of H-1 value as measured by the Modified Von Post Scale, individualizing the harvested peat moss, drying the individualized peat moss and entraining the peat moss in a gas stream. The entrained peat moss is then condensed to form a low density peat moss containing board which is subsequently calendered for use in such products as dressings, diapers and sanitary napkins.
