Abstract
Nonwoven textile fabrics in accordance with the present invention are formed primarily of individualized bast fibers substantially free of pectin. The nonwoven fabric 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 textile fabric is formed into a web while in a dry state and subsequently bonded to produce a nonwoven fabric.
