摘　　要：滩羊毛的隔热性能和吸声性能受多种因素影响。隔热性能受滩羊毛中静止空气含量的影响很大,其中,纤维的细度、比表面积和表面粗糙度都产生影响。吸声性能受滩羊毛含气量和纤维数量的影响很大,其中,纤维的细度、比表面积、孔隙率和孔径分布都产生影响。通过观察发现,纤维的细度、比表面积以及表面粗糙度的变化规律与材料隔热性能和吸声性能的变化规律一致。研究材料的隔热性能和吸声性能可为挖掘滩羊毛的应用潜力提供参考。The thermal insulation performance and sound absorption performance of Tan sheep wool are affected by many factors.The thermal insulation performance is greatly affected by the content of still air in the Tan sheep wool,among which the fineness,the specific surface area and the surface roughness of the fiber all have an effect on it.The sound absorption performance is greatly affected by the air content and the number of fibers in the Tan sheep wool,among which the fineness,the specific surface area,the porosity and the pore size distribution of the fiber are all have an effect on it.Through observation,it is found that the change law of fiber fineness,fiber specific surface area and fiber surface roughness is consistent with the change law of thermal insulation and sound absorption performance of the material.The research on the thermal insulation performance and sound absorption performance of the material can provide a reference for mining the application potential of Tan sheep wool.
