柔性吸声隔音降噪纺织复合材料

柔性吸声隔音降噪纺织复合材料由于能够提供比传统纺织品更宽的吸声域，比传统降噪材料轻薄、柔软、透气和易加工而备受关注。开发基于纺织材料的聚合物复合材料是近年来噪声控制领域的热点研究方向之一。本文从新型纤维、降噪功能填料和柔性降噪纺织复合材料3个方面综述了国内外柔性吸声隔音纺织品的研究进展，并归纳总结了柔性降噪纺织品的制备方法，进一步对柔性吸声隔音降噪纺织品的发展趋势进行了展望。

Sound-absorbing and sound insulation soft composite materials of textile for noise reduction

Soft composite materials of sound-absorbing and sound insulation textiles as a new-type noise reduction materials have drawn much attention because they can provide wider sound absorption band than traditional textiles and lighter, more softer, more breathable and easier to process than traditional noise reduction materials. Consequently, significant research interest in the field of noise control has been directed into the research of polymer composites based on textile materials. In this paper, a review of the research progress of soft textiles of sound-absorbing and sound insulation materils from three aspects of novel type fiber, functional fillers of noise reduction and soft noise reduction composites was presented. Furthermore, the preparation method and the developing trend of soft noise-reducing textiles were summarized.
