According to performance and raw materials, sound-absorbing soft bags can be divided into several categories: fireproof sound-absorbing soft bags, fabric sound-absorbing soft bags, leather sound-absorbing soft bags, and non-woven sound-absorbing soft bags. 1. Fire resistant and sound-absorbing soft packaging is a new type of material with fire resistance performance. Its biggest feature is to meet the defensive properties that buildings and structures must achieve during use, while not affecting the performance of other functions. Currently, fire resistant and sound-absorbing soft packaging is widely welcomed in project engineering and public places. 2. Fabric sound-absorbing soft bag is a type of sound-absorbing material that uses fabric as raw material and is specially treated to block the propagation of sound sources. Fabric sound-absorbing soft bag has the basic characteristics of non toxicity and environmental protection, and also has a special decorative effect. Currently, the product is highly praised by the public. 3. Leather sound-absorbing soft bags are a type of sound-absorbing material made of artificial leather. Leather sound-absorbing soft bags have the functions of optional color, dust prevention, decoration, sound absorption, etc. They also have the basic properties of insulation. Currently, leather sound-absorbing soft bags are mainly used in places such as karaoke, KTV, cinemas, dance halls, etc. that require multi-color processing. 4. Non woven sound-absorbing soft bag is a type of sound-absorbing material made of non-woven fabric. Currently, the use of such sound-absorbing materials is not particularly widespread, but it can also be seen in special construction occasions (such as insulation and sound insulation).
