Improvements in or Relating to Pressed Felts

摘要

A method of making a pressed felt is disclosed wherein a batt including animal and heterofibres is formed and the animal fibres felted together mechanically to interlock to form a matrix supporting the heterofibres. The batt can be subsequently heated to cause the heterofibres to interlock to form a second cohesive matrix adding further strength to the felt. The matrices can be intimately interlaced or arranged in discrete layers.
