Porous structure and in built capillary ducts of wool felt enhances suction capability of felt which helps in transmission of liquids. These absorbed liquids are slowly released allowing the felt to also act as an efficient medium of lubrication. Dry & wet filtration of suspended particles in air & gas is also due to the porous structure of wool felt. Characteristic like elasticity and resistance to wear helps wool felt to be used as “Pressure Pads” in steel service centres during slitting & shearing operations. It also acts as “coolant wiper” thus serving a dual purpose in an industry. Resilience, an inherent characteristics of sheep wool fibre, results in a good sealing agent. It can prevent leakage of dust, noise, heat, cold etc. Air trapped in the porous structure of wool felt makes this material an excellent insulation material. High porous structure makes wool felt a poor conductor of sound waves & vibrations.
