ABSTRACT:
Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed. The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can be hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers. The hydraulic entangling technique provides a nonwoven fibrous elastic material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance. A smooth surfaced and/or highly absorbent elastic web material, with isotropic strength and recovery in both machine- and cross-directions, can be provided according to the present invention.
