Abstract
A hemp-based nonwoven material manufactured by an air bonding process comprising a temperature of 150° C. for two minutes; said nonwoven material comprising between 1% and 99% hemp and between 1% and 99% of at least a second fiber; wherein the at least a second fiber is a synthetic fiber having a melt temperature of above 150° C.
Claims37
A hemp based nonwoven material comprising between 1 and 100% by weight of hemp fibers and a second material comprising between 1 and 99% total weight of the nonwoven material;
- wherein said hemp fibers are saturated with a solvent and blended;
- wherein said solvent and fibers are filtered;
- and wherein the fibers can be processed into nonwoven materials via air-laid, carding, and wet-laid, and bonded via hydroentanglement, needle punching, or adhesive bonding.
