Abstract
Water dispersible nonwoven substrates in accordance with the present invention are formed primarily of individualized bast fibers substantially free of pectin. The nonwoven substrate can include staple fibers to a lesser extent than the individualized bast fibers. Individualized bast fibers include fibers derived from the flax and hemp plants. The nonwoven substrate is formed into a web in a wet or a dry state and subsequently bonded to produce a water dispersible nonwoven substrate. The nonwoven substrate can be a tissue or a wet wipe.

A water dispersible nonwoven substrate comprising a majority of individualized bast fibers which are substantially straight, substantially pectin-free, and have a mean length greater than 4 millimeters (mm).
A water dispersible nonwoven substrate comprising a majority of individualized bast fibers which are substantially straight, non-cotton, plant-based, and substantially pectin-free and have mean length greater than 4 mm.
A water dispersible nonwoven substrate comprising individualized bast fibers with less than 20% of the pectin content of the naturally occurring bundled bast fiber from which the individualized bast fibers are derived, the individualized bast fibers being formed into an unbounded web in the dry state, and the bast fibers having a mean length greater than 4 mm.
