1. A premoistened nonwoven web, said web consisting essentially of at least 90% by weight of non-thermoplastic fibers comprising rayon fibers and pulp fiber, wherein at least 20% by weight of said non-thermoplastic fibers have a fiber length of at least 18 mm and wherein said web comprises a greater amount of rayon fibers than pulp fibers, wherein said web comprises: (a) a surface;(b) a plurality of visible compressed sites formed under a compressive stress of at least 200 N/mm2 located on said surface, said compressed sites comprising un-melted, weakened fibers providing a cloth-like texture that is maintained even when wet; and(c) lines of weakness; wherein the premoistened nonwoven web at least partially fails in tension along the lines of weakness when the premoistened nonwoven web is flushed into a plumbing system. 2. The nonwoven web of claim 1, wherein said web is carded and spunlaced. 3. The nonwoven web of claim 1, wherein said non-thermoplastic fibers further comprise fibers selected from the group consisting of: cotton, wool, silk, jute, linen, ramie, hemp, flax, camel hair, kenaf, and mixtures thereof. 4.

The nonwoven web of claim 1, wherein said rayon fibers are selected from the group consisting of: viscose, lyocell and mixtures thereof. 6. The nonwoven web of claim 1, wherein said web comprises from about 80% to about 20% by weight of said pulp fibers. 7. The nonwoven web of claim 1, wherein said web further comprises a binder. 8. The nonwoven web of claim 7, wherein said web comprises less than or equal to 10% by weight of binder. 9. A wipe comprising the nonwoven web of claim 1, wherein said wipe has a basis weight of from about 30 to about 150 grams per square meter and is pre-moistened with a lotion. 10.
