摘要
设计制备了3组不同混纺比的聚对苯撑苯并二噁唑(PBO)纤维/间位芳纶混纺水刺非织造布隔热层面料,PBO纤维与间位芳纶的质量比分别为10/90、20/80和30/70。将制备的PBO纤维/间位芳纶混纺水刺非织造布与市售常规芳纶隔热水刺非织造布(对位芳纶与间位芳纶质量比为20/80)进行性能测试对比,探究不同混纺比PBO纤维/间位芳纶混纺水刺非织造布的热防护性能和应用潜力。研究结果表明:3组PBO纤维/间位芳纶混纺水刺非织造布均表现出优异的热防护效果,没有因PBO纤维的高导热率而降低灭火服组合的热防护性能,其中,PBO纤维与间位芳纶混纺比为20/80时,混纺水刺非织造布的热防护性能最佳。
Three groups of poly(p-phenyl benzoxazole)(PBO)fiber/Meta-aramid blended spunlaced felts were designed and prepared as thermal insulation fabrics.The mass ratios of PBO fiber to Meta-aramid were 10/90,20/80 and 30/70,respectively.The performance of the prepared PBO fiber/Meta-aramid blended spunlaced felts was tested and compared with commercially available conventional aramid thermal insulation spunlaced felts(mass ratio of Para-aramid to Meta-aramid was 20/80).and t The thermal protection performance characteristics and practical potential of PBO fiber/Meta-aramid blended spunlaced felts with different blending ratios were investigated.The results indicated that the three groups of PBO fiber/Meta-aramid blended spunlaced felts showed excellent thermal protection effect,and the high thermal conductivity of PBO fiber did not reduce the thermal protection performance of the combined spunlaced felts combination of fire fighting suits.Among them,spunlaced blended spunlace felts with the mass ratio of PBO fiber to Meta-aramid fiber of 20/80 showed the best thermal protection performance.
