Formation of Leather Sheet Material Using Hydroentanglement

摘要

Leather sheet material is made by hydroentangling a web ( 4 ) of mixed reclaimed leather fibres and synthetic fibres. The synthetic fibres are meltable bicomponent fibres which are heated prior to entanglement to fuse and form a supporting network for the leather fibres. A sheet of tissue paper ( 1 a) is laid over the surface of the leather fibre web ( 4 ) and hydroentanglement jets ( 16 ) are directed through the tissue paper into the web.
