Hemp non-woven fabric

Hemp non-woven fabric is an eco-friendly technical textile composed of industrial hemp (Cannabis sativa) fibers that are not woven but mechanically, thermally, or chemically bonded into a non-woven web. The history of non-woven fabrics began in the 1940s when natural fibers such as cotton and linen were used, while hemp non-woven fabric started developing in the 1990s alongside the renewed interest in hemp within the textile industry. Production involves harvesting hemp stalks, mechanically separating fibers from the shives, cleaning them, and then processing them into felted or needled webs using carding, needle-punching, or thermal technologies. The resulting non-woven fabric is strong, vapor-permeable, breathable, absorbent, and exhibits good acoustic and thermal insulation properties. The combination of hemp's natural characteristics, low cultivation requirements, and high durability makes it a promising alternative to synthetic non-woven materials and a significant trend in the circular textile industry.
