摘要
选用珍珠纤维、莫代尔纤维、大豆纤维、竹纤维、聚乳酸纤维等新型再生纤维及普通棉共9种针织内衣织物进行对比实验。使用GB/T11048—1989平板式保温仪法与GB/Tl2704—1991透湿杯法等常规方法对试样进行测试,得出各试样的热湿舒适性能指标,并与ISO11092出汗热板仪法测出的试样热阻、湿阻结果进行了比较,运用灰色理论分析两者在评价织物热湿舒适性能方面的关联度。结果显示:热阻与克罗值的关联度最大,湿阻与当量透湿量的关联度最大,说明常规方法测得的克罗值和当量透湿量与用出汗热板仪测得的热阻和湿阻同样能够较好地反映织物的热湿舒适性能。在评价此类织物的热湿舒适性能时,可以考虑用常规方法测得的克罗值和当量透湿量来取代出汗热板仪法测得的热阻和湿阻,以降低测试成本。
Experiments of 9 knitting underwear fabrics making of cotton and new regenerated fibers,such as pearl fiber,modal fiber,soybean fiber,bamboo fiber and PLA fiber were made.The heat-moisture comfort performance was tested with GB/T 11048—1989 plate warmth retention instrument method and GB/T 12074— 1991 water vapor transmission dish method,and was compared with the thermal insulation and moisture vapor resistance values testing from ISO 11092 sweating hot plate.Then the experimental results with grey theory to study the correlation of them in evaluating heat-moisture comfort performance of fabrics were analyzed.The result was shown that thermal insulation was made the largest correlation with the＂clo＂value,moisture vapor resistance was made the largest correlation with＂equivalent water vapor transmission＂.It was shown that the conventional methods also can make the better reflection of heat-moisture comfort performance with fabrics compared with the sweating hot plate instrument.In evaluating the heat-moisture comfort performance of fabrics,it can take into account of using the＂clo＂value and＂equivalent water vapor transmission＂testing with conventional method to substitute the thermal insulation and moisture vapor resistance values from sweating hot plate in order to reduce testing costs.
