摘要
以再生聚酯纤维与双组分低熔点聚酯纤维为原料,利用非织造生产工艺,采用针刺及热风加固方法,制备再生聚酯纤维吸声板材,探究其结构与吸声性能的特点,并利用C6环保型氟系低温整理剂TG-5502对其进行防污整理。结果显示:再生聚酯纤维吸声板材是一种多孔轻质材料,孔隙率为82.04%～84.81%,密度为209.60～247.84 kg/m^3,孔径分布主要集中在20.00～60.00与75.00～100.00μm;再生聚酯纤维吸声板材的平均吸声系数为0.30～0.43,在4 000 Hz及以上高频段具有较好的吸声性能;经防污整理后,再生聚酯纤维吸声板材的接触角提升到137.0°,水滴移动的倾斜角下降到19.0°,材料耐沾污、易去污。
The regenerated polyester fiber sound-absorbing plates were prepared with recycled polyester fibers and bi-component and low-melting polyester fibers as raw materials, by using nonwovens production process with needling and hot air reinforcement methods. Their characteristics of structure and sound absorption performance were explored, and then anti-fouling finishing was done by using the environmental fluorine-based low-temperature finishing agent TG-5502. The results showed that, the regenerated polyester fiber sound-absorbing plate was a kind of porous and lightweight material with porosity of 82.04%~84.81%, the density of 209.60 ~ 247.84 kg/m^3, and the pore size distribution mainly concentrated in 20.00~60.00 and 75.00~100.00 μm. The average sound absorption coefficient of the regenerated polyester fiber sound-absorbing plate was 0.30~0.43, whose sound absorption performance was better in high frequency band of 4 000 Hz and above. After anti-fouling finishing, the contact angles of the regenerated polyester fiber sound-absorbing plate raised to 137.0°, the inclination angles at which water droplets moved reduced to 19.0°. The materials were stain-resistant and easy to decontaminate.
