Abstract
A method for manufacturing a peat moss board suitable for use as an absorbent core in structures for absorbing body exudate. The method is characterized by conditioning a wet laid board to a specific water content and calendering the conditioned board at a predetermined pressure. The water content and the calendering pressure determine the density of the peat moss board in final form. The invention also extends to a peat moss board manufactured by the novel method.
