Polyester fiber sound-absorbing board is made of imported three-dimensional hollow polyester fiber yarn by high-temperature hot pressing and made in the shape of cocoon. The public heat treatment method realizes the density diversity, sound absorption, flame resistance, non-toxic and harmless, non-irritating, and non-odor , To become an excellent product in sound-absorbing and heat-insulating materials that replace glass fiber and asbestos fiber. The sound-absorbing body composed of polyester fiber sound-absorbing board not only has high sound absorption coefficient, wide sound absorption frequency, that is, excellent acoustic performance, but also has good physical and mechanical properties and interior decoration properties.
The second is that fabric soft-packed sound-absorbing panels are generally used on seats in movie theaters. It is a sound-absorbing panel that is very suitable for movie theaters. It is also a kind of sound-absorbing material for movie theaters.
The fabric soft-packed sound-absorbing board has a rich and colorful choice of finishes, which can be customized according to the individual requirements of users, providing the greatest possibility for achieving your goals. The fabric soft bag has a wide sound absorption spectrum and a high sound absorption coefficient, and has a better sound absorption effect for low, medium and high frequency noise. The fire protection level has reached the national approval level B and the environmental protection is the national E1 level. The above two materials are very suitable for sound absorption in movie theaters.
