酚醛纤维织物热湿舒适性的灰色聚类分析

Gray clustering analysis on thermal-moisture comfort of phenolic fiber fabrics

为了解酚醛纤维织物的热湿舒适性,将酚醛纤维织物应用于消防领域,以酚醛纤维织物及消防服常用的阻燃棉布、芳纶1313织物、聚酰亚胺织物为研究对象,对隔热性、保温性、透湿性、透气性和输水性这5个指标进行测试,研究相同面密度的不同种类织物的热湿舒适性。利用灰色聚类分析理论对5个指标进行聚类分析,对这4种织物在不同环境下的热湿舒适性能做了综合评价。结果表明:在高温条件下,酚醛纤维织物具有较好的热湿舒适性,聚酰亚胺织物与阻燃棉布次之,芳纶1313织物最差;在低温条件下,酚醛纤维织物也具有良好的热湿舒适性,聚酰亚胺织物次之,芳纶1313织物与阻燃棉布最差。

The phenolic fiber fabrics and the flame retardant cotton,aramid 1313 and polyimide fabric which are commonly used in the fire-fighting suit field were taken as research objectives with a view to understand the thermal-moisture comfort of phenolic fiber fabrics and apply it in the fire fighting field.The heat insulation,thermal insulation,moisture permeability,air permeability and water permeability of fabrics were tested,and the thermal-moisture comfort of fabrics with same weight and different kinds were studied. By using the gray cluster analysis,the integrated evaluation of thermal-moisture comfort of the four fabrics under different environmental conditions were conducted. The results show that： under the high temperature conditions,the phenolic fiber fabric has good thermal-moisture comfort,the polyimide fabric and flame retardant cotton fabric are the second,and the aramid 1313 fabric is the worst; and under the low temperature condition,the phenolic fiber fabric has good thermal-moisture comfort,the polyimide fabric is the second,and the flame retardant cotton fabric and the aramid 1313 fabric are the worst.
