Sound absorption and noise reduction fabric
The invention discloses a sound absorption and noise reduction fabric, and belongs to the technical field of sound absorption fabrics, the sound absorption and noise reduction fabric comprises flannelette, the flannelette comprises a base fabric, a high-flannelette layer and a low-flannelette layer which are uniformly distributed are arranged at the top of the base fabric, sound absorption cloth is bonded and fixed at the bottom of the flannelette, the sound absorption cloth comprises a sound absorption layer, and ePTFE films are bonded and fixed on two sides of the sound absorption layer; according to the flannelette, the base cloth is heightened, the low fluff layer is arranged, so that the flannelette has the sound absorption performance, noise is collided and attenuated between fluff of the high fluff layer and the low fluff layer, the noise which is not absorbed penetrates through the flannelette and enters the sound absorption cloth to be absorbed by the sound absorption layer, the sound absorption effect is good, the sound absorption material in a fabric form is convenient to add in the later period, and the practicability of the fabric is high.
本发明公开了一种吸声降噪面料，属于吸声面料技术领域，包括绒布，绒布包括底布，底布顶部设有均匀分布的高绒层、低绒层，绒布底部粘结固定有吸音布，吸音布包括吸音层，吸音层两侧均粘结固定有ePTFE膜；通过将绒布设置为底布加高、低绒层，使绒布具备吸声性能，噪声在高、低绒层的绒毛间碰撞衰减，未能吸收的噪声透过绒布进入吸音布内，被吸音层吸收，吸声效果好，面料形式的吸声材料，便于后期加装，面料的实用性高。
