Non-woven fabric tape is a type of tape that is made from fibers that are bonded together using heat, chemicals, or pressure, rather than being woven together. It is often used as a water-blocking tape in cables to prevent water ingress into the cable. The non-woven fabric tape is typically impregnated with a water-blocking material, such as a superabsorbent polymer, to enhance its water-blocking properties. The tape is wrapped around the cable core and serves as a barrier against water, preventing it from entering the cable and potentially causing damage.
