A composite nonwoven fabric is formed by providing a synthetic fiber web (10 ) comprising staple length polymeric fibers, and a cellulosic fiber web (11), preferably comprising wood pulp fibers. Prior to integration of the webs, th e synthetic fiber web is subjected to hydroentangling to form a partially entangled web, with the cellulosic fiber web thereafter juxtaposed with the partially entangled web for hydroentanglement and integration of the web. Pr e- entanglement of the synthetic fiber web desirably acts to minimize the energ y input required for integration of the cellulosic fiber and synthetic fiber webs, and also desirably acts to abate loss of the cellulosic fibers during hydroentanglement and integration of webs. |
