Abstract
A reinforced hydroentangled nonwoven fabric having small thickness and weight, draping characteristics and flexibility, and improved balance of longitudinal and transverse strength, and more particularly a thin, light-weight, reinforced, hydroentangled nonwoven fabric (9) obtained by entangling the fiber of a reinforcing support base (2) or the fiber of a fiber web laminated on the fiber of the support base (2) with the support base (2) and uniting them by ejecting high-pressure thin water jet streams (5a, 5b) against these materials, characterized in that the reinforcing support base (2) comprises a stretched unidirectionally oriented nonwoven fabric obtained by stretching a nonwoven fabric of long fiber, which is produced by spinning a thermoplastic resin, in the direction with the fiber oriented substantially in one direction, or stretched, crossed, laminated, nonwoven fabric obtained by cross-laminating the stretched unidirectionally oriented nonwoven fabric; and a method of producing the same.
