Formation of leather sheet material using hydroentanglement

摘要

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