Abstract
Disclosed herein is a reflectively patterned, fibrous, sided nonwoven material comprising a first set of fibers hydraulically needled with a web of a second set of fibers, the first set of fibers primarily containing short fibers and the second set of fibers primarily containing one of (a) substantially continuous filaments, (b) long fibers, and (c) short fibers having an average fiber length at least twice the average fiber length of the first set of fibers. The material has a first surface predominately comprising the first set of fibers and an opposing second surface predominately comprising the second set of fibers. A method of patterning a sided nonwoven web and a reflectively patterned, sided nonwoven material also are disclosed.
