ABSTRACT OF THE DISCLOSURE: Nonwoven fibrous non-elastic webs, reinfored nonwoven fibrous non-elastic webs and methods of forming the same are disclosed. The nonwoven fibrous non-elastic webs are a hydraulically entangled coform or admixture of non- elastic meltblown fibers and fibrous material, with or without particulate material. The fibrous material, (e.g., non-elastic fibrous material) can be at least on of pulp fibers, staple fibers, meltblown fibers and continuous filaments. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the more effective use of shorter fibrous material. The hydraulic entangling technique pro- vides a nonwoven fibrous material having increased web strength and allows for better control of other product attributes, such as absorbency, wet strength, printability and abrasion resistance. The coform can be hydraulically entangled with a reinforcing material, e.g., a melt-spun nonwoven, a scrim, screen, net, etc.
