Felt is an excellent insulating material
The main characteristics of the felt are elasticity, which can be used as materials for shockproof, sealing, cushioning and elastic steel wire cloth felt. In addition, the felt products have good insulation and are excellent insulating materials.
Hair fiber is non-conductive and is an excellent insulating material. Therefore, some electrical instruments, meters, etc. are insulated with wool felt. Hair fibers rub against each other with static electricity. The electrostatic phenomenon of wool has little effect on the production of felt products, but it has a greater impact on the wool textile industry. Wool fibers are one of the less thermally conductive materials in textile fibers. A small thermal conductivity is good for warmth. Therefore, herders and geologists living in the grasslands all use felt as tents, and some also wear felt boots, felt cloths, and felt socks. The felt is not made of warp-knitted fabrics, so it has good filterability and can be used for sucking oil. Most of the tanks under the steamer use felt to keep the ship clean.
The use of felt: Felt is mainly used in light industry, can also be used for marble, stainless steel, precision furniture polishing, aircraft, automobiles, trains, ships, machine tools and other equipment dust, sealing, sound insulation, insulation, insulation, insulation and so on.
