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.
Claims135
A nonwoven fabric comprising a majority of full length natural individualized fibers which are substantially straight, plant-based, smooth and elongated, and substantially pectin-free and have a mean length greater than 6 millimeters (mm).
A nonwoven fabric comprising a majority of full length natural individualized fibers which are substantially straight, non-cotton, plant-based, smooth and elongated, and substantially pectin-free and are un-cut with a distribution of fiber lengths and a mean length greater than 10 mm.
A nonwoven fabric comprising a majority of full length natural individualized fibers which are substantially straight, plant-based, smooth and elongated, and have a mean length greater than 10 mm.
A nonwoven fabric formed of a majority of fibers comprising substantially straight, full length natural individualized bast fibers with less than 10% 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 being smooth and elongated and having a mean length greater than 12 mm.
A nonwoven fabric comprising about 85 weight percent individualized fibers and about 15 weight percent regenerated cellulose fibers, based upon total fiber weight, the fibers being full length natural individualized fibers which are substantially straight, plant-based, smooth and elongated, and substantially pectin-free and have a mean length greater than 6 mm.
