Zusammenfassung: | The invention discloses a sound-absorbing fabric enabling materials to be in contact electrification based on vibration and a preparation method of the sound-absorbing fabric, and belongs to the field of sound-absorbing materials. The sound absorption fabric is composed of a ground weave unit layer, a consolidation unit layer and a vibration unit layer, and the three units form a single-layer, double-layer or multi-layer fabric containing a simply supported beam vibration string structure or a cantilever beam vibration arm structure through different preparation methods. The static sequences of at least two materials including a vibration unit yarn material in the fabric are different, sound energy is converted into electric energy through contact separation and charge transfer, meanwhile, the sound energy is converted into heat energy through the porous structure of the fabric, and the multiple sound absorption effect is achieved. On the basis of the porous sound absorption principle, the fabric has an addit |
