【摘要】 为了更好地利用酚醛纤维的热学性能开发适合应用的隔热织物，基于其纤维规格及性能，以聚酰亚胺纤维与其进行混纺，详述其原料处理、混纺比例、流程设计、梳理成条、粗纱、细纱工序的工艺要点，在尽可能提高酚醛纤维含量的基础上，纺制出酚醛纤维含量为40%～70%的4种32 tex混纺纱线，并对混纺纱的指标进行测试与分析。指出：在酚醛纤维/聚酰亚胺纤维混纺纱中，随着酚醛纤维含量增大，纱线的断裂强度、毛羽指数、条干CV值以及千米节结等质量指标均呈恶化趋势；酚醛纤维的含量最高能达到约70%水平。更多还原

【Abstract】 In order to make better use of the physical properties of phenolic fiber to develop thermal insulation fabric suitable for application, on the basis of its fiber specifications and properties, polyimide fiber is blended with phenolic fiber, and the technological points of its raw material treatment, blending ratio, process design, carding into sliver, roving and spinning are described in detail.With the content of phenolic fiber as high as possible, four kinds of 32 tex blended yarns with phenolic fiber content of 40%～70% are spun, and the indexes of blended yarns are tested and analyzed.It is pointed out that in phenolic fiber/polyimide fiber blended yarn, with the increase of phenolic fiber content, the yarn quality indexes such as breaking strength, hairiness index, the value of evenness CV,thousand-meter knot and so on are deteriorating.The content of phenolic fiber can reach about 70% at the highest level.更多还原
