Abstract
Here are disclosed a composite non-woven fabric having a high dimensional stability and a process for preparing such non-woven fabaric. This non-woven fabric is prepared by a cross-stretching starting non-woven fabric obtained by a fiber entanglement treatment of a staple fiber web by fluid jets to form a substrate, then introducing short fibers onto this cross-stretched substrate and filling said cross-stretched substrate with said short fibers by further fiber entanglement treatment also by fluid jets. Such composite non-woven fabric is suitable particularly as cloth for disposable medican garments or the like.
